Technical Field

The present invention relates to a computing device, a display method for the computing device, and a recording medium for the computing device.

Background

Patent document 1 discloses a calculation device that includes an input unit for inputting an operand and an operand, and presents a first result and a second result, which are results obtained by performing arithmetic operations on the operand input through the input unit, to a user, and specifically, the calculation device disclosed in patent document 1 can perform a quotient and remainder calculation (div-remainder calculation) in which a quotient (first result) and a remainder (second result) of a division result are presented to the user in addition to a normal division operation.

However, although such a calculation device has a demand for calculation in which it is desired to know a first result total, which is a total of first results (for example, quotients) when a plurality of calculations are performed with a specific operand, and a second result total, which is a total of second results (for example, remainders), a calculation device having a function of easily displaying the first result total and the second result total has not been realized.

The calculation requirements described above are not limited to the above example, and include, for example, the following requirements. Assuming that a certain product is stored in a warehouse in a state that 7 pieces of the product are packed in one box and packed, an operator takes the product stored in the warehouse in accordance with the order received. In this situation, when 200 or 300 orders are received from different orderers, it is problematic for the operator to take several boxes and several products in bulk in the warehouse.

In this case, conventionally, when "2", "0", "div", "7" is entered, the quotient "28" is displayed on the display unit as a first result of the first operation, and the remainder "4" is displayed on the display unit as a second result of the first operation by pressing the "remainder" key, so that the operator records the quotient (28) and remainder (4) of the first operation. Next, when "3", "0", "÷", "7" is entered, the quotient "42" is displayed on the display unit as the first result of the second calculation, and the remainder "6" is displayed on the display unit as the second result of the second calculation, so that the operator records the quotient (42) and remainder (6) of the second calculation.

The operator calculates the total of the first and second quotients in order to calculate the number of boxes and the number of scattered items of the commodity taken out of the warehouse. Specifically, "2", "8", "plus", "4", "2" or "not" is typed to obtain a bin number "70". Similarly, the number of scatters "10" is obtained by entering "4" + "6" ═ or ". As described above, when it is desired to know a first result total which is a total of first results (for example, quotients) and a second result total which is a total of second results (for example, remainders) when a specific operand (here, "7") is operated a plurality of times, it is necessary to record the calculation results of the first operation first, and further, it is necessary to input each calculation result of the first operation and the second operation again at the calculation total time, which makes the operation very complicated.

In addition, as described above, since the divisor "7" must be input every time the first and second calculations are performed, the same divisor must be input repeatedly, which makes the operation of obtaining a desired calculation result complicated.

Detailed Description

Hereinafter, a mode for carrying out the present invention (hereinafter, referred to as "embodiment") will be described in detail with reference to the drawings.

In addition, like elements are denoted by like reference numerals throughout the description of the embodiments.

[ Overall Structure of computing device ]

Fig. 1 is a front view of a computing device 1 according to an embodiment of the present invention, and fig. 2 is a block diagram showing a configuration of the computing device 1 according to the embodiment of the present invention.

As shown in fig. 1 and 2, the CPU11 controls the operation of the computing apparatus 1.

The CPU11 is connected to the key input unit 12 (input unit), the memory 13, the display unit 14, and the recording medium reading unit 15.

The key input unit 12 includes numeric keys "0 to 9" for numerical value calculation, operator keys "+, -, ×, ÷", a quotient remainder calculation key "÷ remainder" (operation instruction key), a quotient remainder total key "quotient and remainder total", a clear key "C", a full clear key "AC", a calculation execution key "═ and the like.

Here, when performing the quotient and remainder calculation, that is, calculating the quotient (first result) obtained by dividing the operated number by the operated number and the remainder (second result) obtained by dividing the operated number by the operated number, the quotient and remainder calculation key "÷ remainder" is operated instead of the normal division operator key "÷ remainder".

The function of the quotient and remainder total key "quotient and remainder total" will be described below.

The memory 13 is composed of a ROM and a RAM.

The ROM of the memory 13 stores a calculation processing program for causing the CPU11 to function as a control unit, and the processing described later is executed by the CPU11 as a control unit, which will be hereinafter simply referred to as the CPU 11.

The RAM of the memory 13 stores entered numerical data and numerical data of the operation result as needed.

For example, in the present embodiment, an operand storage area for storing a divisor of an operand calculated as a quotient remainder, and a quotient remainder storage area for storing a quotient total (first result total), a remainder total (second result total), and an operand (divisor), which will be described later, are secured in the RAM of the memory 13.

The display unit 14 displays operation numerical data, operation symbols, constant lock marks, and calculation result explanatory character strings corresponding to the key input operation of the key input unit 12.

As will be described later with reference to fig. 4 and 7, for example, when the operator remainder calculation key "÷ remainder" is operated, the operation symbol "÷ remainder" for the calculation of the quotient remainder is displayed, and when the operator remainder calculation key "÷ remainder" is continued, the operation symbol "÷ remainder" for the calculation of the quotient remainder and the constant lock symbol "K" are displayed, and in the result display state of the calculation of the quotient remainder, "quotient", "remainder" are displayed as the calculation result, and in the result display state of the total of the quotient and remainder, "total", "quotient", and "remainder" are displayed as the calculation result.

The recording medium reading unit 15 reads data and programs from a removable recording medium 16 such as a flash memory.

[ first embodiment ]

Next, a control procedure of the computing apparatus 1 according to the first embodiment shown in fig. 3 will be described with reference to an operation example shown in fig. 4.

In the following description, the quotient and remainder calculation is referred to as "÷ remainder" operation.

Fig. 3 is a flowchart showing a control procedure of the computing apparatus 1 according to the first embodiment of the present invention, and (a) to (m) of fig. 4 are explanatory diagrams showing operation examples of the computing apparatus 1 according to the first embodiment of the present invention.

Fig. 4 (a) to (m) show transition of the display screen of the display unit 14 and transition of the numerical value stored in the total quotient and remainder storage area in accordance with operation of the key input unit 12, the operated key being shown on the left side of the display screen, and the stored content of the total quotient and remainder storage area being shown on the right side of the display screen.

After the power is turned on, the computing apparatus 1 enters a state of monitoring which operation of step S101 to step S106 is being performed, as shown in fig. 3.

Then, if the numerical value "7" is input, the CPU11 determines "numerical value input? "yes" (step S102), then, the CPU11 displays "7" on the display unit 14 as shown in fig. 4 a (step S108).

Next, if the "÷ remainder" key is pressed, the CPU11 determines the "÷ remainder key? "yes (step S103)" means that the first operation is a "division remainder" key operation, and therefore, the CPU11 subsequently determines "this time is a continuous? "(step S109)" is NO.

Then, the CPU11 sets the display numerical value "7" as the operated number for the time being, and displays the operation symbol "÷ remainder" above the numerical value "7" on the display unit 14 as shown in fig. 4 (b) (step S111).

Next, when the "÷ remainder" key is pressed again, the input is continuously performed for the second time, and therefore the CPU11 determines that "this time is a continuous ÷ remainder key? "yes" (step S109), the display numerical value "7" is set as the operand, and the constant lock operation state is set as "÷ remainder", and as shown in fig. 4 (b), a constant lock symbol "K" is displayed on the upper left of the display unit 14 (step S110).

In step S110, when the display numerical value "7" is set as the operand, "7" is registered in the operand (divisor) memory of the memory 13 shown in fig. 2.

Next, if the value "200" of the operand is input, that is, the value "2" is input, the value "0" is input, and the value "0" is input, then the CPU11 inputs the "value" of fig. 3? "(step S102) is determined as yes" three times and the CPU11 repeats the process of step S108 three times, so that the numerical value "200" is displayed on the display unit 14 as shown in fig. 4 (c).

Next, when the "═ key is pressed, the CPU11 determines that" ═ key? "(step S104)" yes ", and" ÷ remainder "constant lock operation state" following this? "yes" (step S112) is also determined, so that CPU11 sets display numerical value "200" as a operand, performs "÷ remainder" calculation with constant-locked set operand "7", displays calculation result "28-4" on display unit 14, and displays calculation result explanatory character strings "quotient" and "remainder" at the corresponding positions on the upper side thereof, as shown in fig. 4 (d) (step S113).

Since the present operation is the first operation, the CPU11 displays the result of the? "no" (step S116), the quotient and remainder total memory is cleared, and the operand of this time and the operation result (quotient and remainder) are registered in the quotient and remainder total memory as shown on the right side of fig. 4 (d) (step S119).

Next, if the value "300" of the operand is input, that is, the value "3" is input, the value "0" is input, and the value "0" is input, then the CPU11 inputs the "value" of fig. 3? "(step S102) is determined as yes" three times and the CPU11 repeats the processing of step S108 three times, so that the numerical value "300" is displayed on the display unit 14 as shown in fig. 4 (e).

Next, when the "═ key is pressed, the CPU11 determines that" ═ key? "(step S104)" yes ", and the following" ÷ remainder "constant lock operation state? "yes" (step S112) is also determined, so that CPU11 sets display numerical value "300" as the operated number, performs the "÷ remainder" operation with the operated number "7" set by constant locking, displays the operation result "42-6" on display unit 14, and displays the calculation result explanation character string "quotient" and "remainder" at the corresponding position on the upper side thereof, as shown in fig. 4 (f) (step S113).

Since this time is the second operation, the CPU11 displays the result of the? "(step S116) is determined as" yes ", and" is the next operand of this time the same as the registered operand? "(step S117) is also determined to be YES.

Therefore, the CPU11 then adds the quotient and remainder calculated this time to the quotient and remainder count total memory and registers them as shown on the right side of (f) in fig. 4 (step S118).

Next, when the "total quotient" key is pressed, the CPU11 determines that "total quotient key? "(step S105) is" yes ", and its subsequent" is remainder total smaller than the operand registered in the quotient remainder total memory? "(step S120).

In the above example, since the remainder total value in the quotient and remainder total memory is "10" and is greater than the operand "7" registered in the quotient and remainder total memory, the CPU11 determines that the determination result in step S120 is "no", and the CPU11 recalculates the remainder total value by the operand and updates the quotient and remainder total memory (step S121) so that the remainder total (second result total) in the quotient and remainder total memory is smaller than the operand.

That is, in step S121, the following processing is performed: the remainder total value "10" is divided by an operand "7", the remainder "3" is used as the remainder total value, and the state after the carry added by the quotient "1" and the quotient total value is registered in the quotient and remainder total memory.

Thereafter, as shown in fig. 4 g, the CPU11 displays the quotient and remainder total value "71-3" on the display unit 14, displays the calculation result explanation strings "quotient" and "remainder" at the corresponding positions on the upper side thereof, and further displays the calculation result explanation string "total" on the left side thereof (step S122).

Next, when the "AC" key is pressed, the CPU11 determines that "AC key? "yes" (step S101), then, the CPU11 clears the display on the display unit 14 and releases the constant lock state (step S107), as shown in fig. 4 (h).

When the "AC" key is pressed, the constant lock state is released, and the operand (divisor) in the operand (divisor) memory of the memory 13 shown in fig. 2 is also reset, but the contents of the quotient and remainder count memory are not cleared.

Next, if the value "150" of the operand is input, that is, the value "1" is input, the value "5" is input, and the value "0" is input, then the CPU11 inputs the "value input" of fig. 3? "(step S102) is determined as yes three times and the CPU11 repeats the process of step S108 three times, so that" 150 "is displayed on the display unit 14 as shown in fig. 4 (i).

Next, if the "÷ remainder" key is pressed, the CPU11 determines the "÷ remainder key? "(step S103) is" yes ", and since the previous" AC "key was pressed, the CPU11 applies the following" this time is continuous? "(step S109) is determined as no, and the display numerical value" 150 "is set as the operated number, and as shown in fig. 4 (j), the arithmetic symbol" ÷ remainder "is displayed above the numerical value" 150 "on the display unit 14 (step S111).

Next, when the value "7" of the operand is input, the CPU11 determines "numerical value input? "yes" (step S102) indicates that "7" is displayed on the display unit 14 as shown in fig. 4 (k) (step S108).

Next, when the "═ key is pressed, the CPU11 determines that" ═ key? "(step S104) is yes", and since the previous "AC" key was pressed and the constant lock state was released, the CPU11 will have its subsequent "÷ remainder" constant lock operation state? "(step S112) is determined as NO.

Then, the CPU11 determines the further subsequent operation state of "÷ remainder"? "yes" (step S114), the display numerical value "7" is set as the operand, and the operation of "÷ remainder" is performed with the operand "7" with respect to the immediately preceding set operand "150", and as shown in fig. 4 (l), the operation result "21-3" is displayed on the display unit 14, and the calculation result explanation character strings "quotient" and "remainder" are displayed at the corresponding positions on the upper side thereof (step S115).

On the other hand, as described above, in the previous operation of pressing the "AC" key, since the contents of the quotient and remainder count total memory are not cleared, the CPU11 judges that the result of the "÷ remainder" operation is displayed (step S115), and then "the operand is registered in the quotient and remainder total memory? "(step S116)" is YES.

Then, since the present operand is "7", the CPU11 sets "the present operand is the same value as the registered operand? "(step S117) is also determined as yes", and the CPU11 adds the quotient and remainder calculated this time to the quotient and remainder total memory and registers them as shown on the right side of (l) in fig. 4 (step S118).

Next, when the "total quotient" key is pressed, the CPU11 determines that "total quotient key? "(step S105) is" yes ", and its subsequent" is the remainder total smaller than the operand registered in the quotient remainder total memory? "(step S120).

In the above example, as shown on the right side of (l) in fig. 4, the remainder total value in the quotient remainder total memory is "6" and is smaller than the operand "7" registered in the quotient remainder total memory, and therefore the determination result in step S120 by the CPU11 is "yes".

Therefore, as shown in fig. 4 (m), the CPU11 displays the quotient and remainder total value "92-6" on the display unit 14, displays the calculation result description string "quotient" and "remainder" at the corresponding positions on the upper side thereof, and further displays the calculation result description string "total" on the left side thereof (step S122).

However, in the above example, since "7" is input as shown in (k) of fig. 4 as the operand after the "AC" key is pressed, and when an operand other than "7" is input, the CPU11 determines no in step S117, and therefore the quotient and remainder, which are the results of a new operation after the "AC" key is pressed in step S119, are registered in the quotient and remainder total memory.

According to the control procedure described above, the total of the quotient and the total of the remainder when a plurality of operands are operated with a specific operand can be easily displayed.

Specifically, as described above in a series of flow, when the "÷ remainder" key is input consecutively after an operand is input, the state shifts to a constant lock state in which the operand is fixed, and the "÷ remainder" operation is performed on each of the subsequently input operands by the fixed operand, and the quotient sum and remainder sum obtained by summing up the plurality of quotients and the plurality of remainders that are the result of the calculation is displayed.

In the first embodiment, when the remainder total is greater than the operand, recalculation (carry processing) is performed so that the remainder total is smaller than the operand, and the result is displayed, so that it is not necessary for the user to perform recalculation.

However, even when the remainder total is larger than the operand, it is considered that the following may occur: when the quotient and remainder before recalculation (carry processing) are viewed at once and then the quotient and remainder after recalculation (carry processing) are desired to be viewed, the flowchart of fig. 3 may be performed as in the flowchart of fig. 5.

Fig. 5 is a flowchart for explaining a modification of the first embodiment in which the quotient and remainder after recalculation (carry processing) are visible after the state of the quotient and remainder before recalculation (carry processing) is visible as described above.

The flowchart of fig. 5 differs from the flowchart of fig. 3 in that step SA1 is added between step S120 and step S121.

After step SA1 is added in this manner, when the "total quotient" key is pressed for the first time, the process proceeds to step S122 as the processing after step S120, in accordance with any one of the flows of yes at step S120 or no at step SA 1.

Therefore, the total quotient and remainder values can be displayed on the display unit 14 without performing the step of recalculating (carry processing), i.e., step S121.

On the other hand, the "quotient and remainder sum" key is pressed again thereafter, and "is this time the consecutive quotient and remainder keys? If "yes", in a state where recalculation (carry processing) is possible, the process proceeds to step S121, which is a step of recalculation (carry processing), and then proceeds to step S122, so that the total quotient and remainder value after recalculation (carry processing) is displayed on the display unit 14.

Further, in the first embodiment, in a new operation after the "AC" key is pressed and the operand is reset, the quotient and remainder sums added to the quotient and remainder sum memory as a result of the operation are added as long as the operation of "division by remainder" using the same operand as the previous operation is continued, and the quotient and remainder sums can be displayed in accordance with the operation of the "quotient and remainder sum" key.

In the first embodiment, in a new operation after the "AC" key is pressed and the operands are reset, the quotient and remainder sums added to the quotient and remainder sum memory as a result of the operation are continued by the operation of "division remainder" using the same operand as the last operand, and the quotient and remainder sum memory is cleared by inputting a different operand.

[ second embodiment ]

Next, a control procedure of the computing apparatus 1 according to the second embodiment shown in fig. 6 will be described with reference to an operation example shown in fig. 7.

However, since the second embodiment has many portions that are the same as those already described in the first embodiment, the following description will be mainly given of portions different from those of the first embodiment, and the description of the portions that are the same may be omitted.

Fig. 6 is a flowchart showing a control procedure of the computing apparatus 1 according to the second embodiment of the present invention, and (a) to (m) of fig. 7 are explanatory diagrams showing operation examples of the computing apparatus 1 according to the second embodiment of the present invention.

Fig. 7 (a) to (m) show transition of the display screen of the display unit 14 and transition of the numerical value stored in the total quotient and remainder storage area in accordance with the operation of the key input unit 12, the operated key being shown on the left side of the display screen, and the stored content of the total quotient and remainder storage area being shown on the right side of the display screen.

The control procedure and the display screen in fig. 7 (a) to (f) are the same as those in fig. 4 (a) to (f) according to the first embodiment, and therefore description will be made starting from fig. 7 (g).

When the "total quotient" key is pressed in the state of fig. 7 (f), the CPU11 determines that is the "total quotient key? "yes" (step S105), the process proceeds to step S122, and as shown in fig. 7 (g), the total quotient and remainder value "70-10" is displayed on the display unit 14, and the calculation result explanation character strings "quotient" and "remainder" are displayed at the corresponding positions on the upper side thereof.

That is, the present embodiment is different from the first embodiment in that step S120 and step S121 in fig. 3 of the first embodiment are omitted, and the sum of only the quotient and the sum of only the remainder are directly displayed without performing the recalculation (carry processing).

In addition, regarding the processing from (h) of fig. 7 to (l) of fig. 7, the contents of the quotient and remainder total memory of (g) of fig. 7 are different from those of the quotient and remainder total memory of (g) of fig. 4 because there is no recalculation (carry processing), but the processing contents themselves are the same as those of (h) of fig. 4 to (l) of fig. 4.

In the state of fig. 7 (l), when the "total quotient" key is pressed, the CPU11 determines the "total quotient key? "yes" (step S105), the process proceeds to step S122 again, and the CPU11 displays the quotient and remainder total value "91-13" in a state where recalculation (carry processing) is not performed on the display unit 14, and displays the calculation result caption character strings "quotient" and "remainder" at the corresponding positions on the upper side thereof, as shown in fig. 7 (m).

According to the control procedure of the second embodiment described above, even when the remainder total is larger than the operand, the quotient total and the remainder total can be displayed without carrying out the carry processing by recalculation.

In the second embodiment, if the operation of "÷ remainder" using the same operand as the last operation is continued in the new operation immediately after the "AC" key is pressed, the quotient and remainder sums added to the quotient and remainder sum memory as a result of the operation are cleared by inputting a different operand, but the quotient and remainder sum memory may be cleared in accordance with the operation of the "AC" key.

Although the computing apparatus 1 of the present invention has been described above based on the embodiments, the present invention is not limited to the above embodiments.

For example, the computing apparatus 1 may be allowed to select a mode, and the operation described in the first embodiment may be performed in the case of mode 1, and the operation described in the second embodiment may be performed in the case of mode 2.

As described above, it is obvious to those skilled in the art that various modifications and improvements are possible within the technical scope of the present invention based on the description of the claims.
