Detailed Description

First, the present invention will be briefly described.

In order to solve the above problem, a first aspect of the present invention provides a recording apparatus including: a recording head that performs recording by ejecting liquid onto a recording medium; a discharge unit configured to discharge the recording medium on which recording is performed by the recording head; a discharge tray that receives the recording medium discharged from the discharge unit in a discharge direction from a lower side in a vertical direction; a first blowing unit arranged vertically above the discharge unit and blowing air from an upstream side toward a downstream side in the discharge direction toward one surface of the recording medium discharged to the discharge tray; a second blowing unit arranged between the discharge unit and the discharge tray in a vertical direction, and blowing air from the upstream side to the downstream side with respect to another surface of the recording medium discharged to the discharge tray; and a control unit that controls the first and second air blowing units, and discharges the recording medium by suppressing deformation of the discharged recording medium by the air of the first and second air blowing units.

According to this aspect, the first blowing unit blows air from above in the vertical direction toward the one surface of the recording medium from the upstream side in the discharge direction toward the downstream side, and the second blowing unit blows air from below in the vertical direction toward the other surface of the recording medium from the upstream side in the discharge direction toward the downstream side. That is, the recording medium discharged to the discharge tray is guided to the downstream side so as to be sandwiched between the air from above by the first air blowing unit and the air from below by the second air blowing unit. Therefore, the recording medium discharged to the discharge tray can be prevented from being deformed in the discharge direction, and the stacking property of the recording medium can be improved.

Here, "the other surface of the recording medium" means a surface of the recording medium opposite to the one surface.

In a recording apparatus according to a second aspect of the present invention, in the first aspect, the blowing direction of the first blowing unit and the second blowing unit is changeable, and the control unit blows air from the first blowing unit and the second blowing unit so that an airflow is generated from a width direction center side, which intersects the discharge direction, toward the downstream side and toward the width direction end side with respect to the recording medium discharged to the discharge tray.

According to this aspect, the recording medium can be discharged to the discharge tray while spreading in the width direction in the direction from the upstream side to the downstream side by the airflow from the center side to the end side in the width direction. Therefore, the recording medium discharged to the discharge tray can be prevented from being deformed in the width direction.

A recording apparatus according to a third aspect of the present invention is the recording apparatus according to the first or second aspect, wherein the blowing direction of the first blowing unit and the second blowing unit is changeable, and the control unit causes the first blowing unit and the second blowing unit to blow toward the downstream side and an end portion in a width direction intersecting the discharge direction with respect to the recording medium discharged to the discharge tray.

According to this aspect, the first blowing unit and the second blowing unit blow air toward the downstream side and the width direction end portion of the recording medium discharged to the discharge tray, and therefore, deformation of the recording medium after discharge to the discharge tray, in particular, bending of the downstream side and the width direction end portion of the recording medium can be suppressed.

A recording apparatus according to a fourth aspect of the present invention is the recording apparatus according to any one of the first to third aspects, wherein the recording apparatus includes a third air blowing unit that is disposed between the discharge unit and the discharge tray in a vertical direction and blows air toward an end portion on the upstream side with respect to the recording medium in a state discharged to the discharge tray.

According to this aspect, since the third blowing unit is provided to blow air toward the upstream end of the recording medium in a state discharged to the discharge tray, deformation of the recording medium after discharge to the discharge tray, in particular, bending of the upstream end of the recording medium can be suppressed.

A recording apparatus according to a fifth aspect of the present invention is the recording apparatus according to the fourth aspect, wherein the controller causes the third blowing unit to blow air toward an end portion in a width direction of the recording medium, the end portion being orthogonal to the discharge direction.

According to this aspect, the third blowing section blows air toward the end portion in the width direction of the recording medium, and therefore, the end portion in the width direction can be prevented from being bent while the recording medium is discharged to the rear upstream side of the discharge tray.

In the recording apparatus according to the sixth aspect of the present invention, in the fourth or fifth aspect, the controller causes the first air blowing unit and the third air blowing unit to continuously blow air while the recording medium is discharged from the discharge unit.

According to this aspect, since the first and third air blowing units continuously blow air while the recording medium is discharged from the discharge unit, for example, when a plurality of recording media are discharged from the discharge unit, the effect of suppressing deformation of the recording medium discharged into the discharge tray state can be enhanced.

A seventh aspect of the present invention is directed to the recording apparatus of the sixth aspect, wherein the control unit stops the first air blowing unit and the third air blowing unit from blowing air based on removal of the recording medium from the discharge tray or a predetermined time period after the recording medium is finally discharged from the discharge unit when the recording medium is continuously discharged from the discharge unit.

According to this aspect, unnecessary air blowing can be suppressed when the recording medium is not easily deformed after the recording medium is removed from the discharge tray or after a predetermined time has elapsed since the recording medium is finally discharged from the discharge unit.

A recording apparatus according to an eighth aspect of the present invention is the recording apparatus according to any one of the first to seventh aspects, wherein the recording apparatus includes a fourth air blowing unit that is disposed above the discharge unit in a vertical direction and blows air toward an end portion on the upstream side with respect to the recording medium in a state discharged to the discharge tray.

According to this aspect, since the fourth blowing unit is provided to blow air toward the upstream end of the recording medium in a state discharged to the discharge tray, deformation of the recording medium after discharge to the discharge tray, in particular, bending of the upstream end of the recording medium can be suppressed.

A recording apparatus according to a ninth aspect of the present invention is the recording apparatus according to the eighth aspect, wherein the fourth blowing unit is disposed further toward an outside than the first blowing unit in a width direction intersecting the discharge direction, and the control unit causes the fourth blowing unit to blow air toward an end of the recording medium in the width direction.

According to this aspect, the fourth blowing section blows air toward the end portion in the width direction of the recording medium, and therefore, the end portion in the width direction can be prevented from being bent on the upstream side after the recording medium is discharged to the discharge tray.

A tenth aspect of the present invention is directed to the recording apparatus of the eighth or ninth aspect, wherein the control unit starts the blowing by the fourth blowing unit as the upstream end of the recording medium is discharged from the discharge unit.

According to this aspect, since the fourth blowing section starts blowing air as the upstream end portion of the recording medium is discharged from the discharge section, the fourth blowing section blows air to the upstream end portion as the upstream end portion is discharged from the discharge section, and the effect of suppressing deformation of the recording medium during discharge from the discharge section can be improved.

A recording apparatus according to an eleventh aspect of the present invention is the recording apparatus according to the tenth aspect, wherein when the recording medium is continuously discharged from the discharge unit, the control unit stops the air blowing by the fourth air blowing unit until the discharge from the discharge unit is started from the end of the downstream side of the succeeding recording medium discharged from the discharge unit following the preceding recording medium.

When the fourth blowing unit continues blowing air even after the recording medium is discharged from the discharge unit first and the downstream end of the subsequent recording medium starts to be discharged from the discharge unit, the downstream end of the subsequent recording medium may be deformed by blowing air from the fourth blowing unit. However, according to this aspect, after the recording medium is discharged from the discharge unit first, the fourth blowing unit stops blowing until the end portion on the downstream side in the succeeding recording medium starts to be discharged from the discharge unit, and therefore, the deformation of the end portion on the downstream side in the succeeding recording medium can be suppressed.

A recording apparatus according to a twelfth aspect of the present invention is characterized in that, in the tenth or eleventh aspect, the control unit stops the fourth air blowing unit from blowing air based on removal of the recording medium from the discharge tray or a lapse of a predetermined time from the last discharge of the recording medium from the discharge unit when the recording medium is continuously discharged from the discharge unit.

According to this aspect, unnecessary air blowing can be suppressed when the recording medium is not easily deformed after the recording medium is removed from the discharge tray or after a predetermined time has elapsed since the recording medium is finally discharged from the discharge unit.

A recording apparatus according to a thirteenth aspect of the present invention is the recording apparatus of any one of the eighth to twelfth aspects, wherein the control unit changes the blowing direction of the first blowing unit and the fourth blowing unit in accordance with a position of an end portion in a width direction intersecting the discharge direction of the recording medium in a state discharged to the discharge tray.

According to this aspect, the first blowing unit can suppress deformation of the downstream side end portion in the width direction of the recording medium, and the fourth blowing unit can suppress deformation of the upstream side end portion in the width direction of the recording medium.

A recording apparatus according to a fourteenth aspect of the present invention is the recording apparatus of any one of the first to thirteenth aspects, wherein the control unit causes the second blowing unit to blow air from the downstream end of the recording medium from the discharge unit to the upstream end of the recording medium from the discharge unit, and causes the second blowing unit to stop blowing air as the upstream end of the recording medium is discharged from the discharge unit.

According to this aspect, the second blowing section blows air from the discharge section to the discharge section from the end on the downstream side of the recording medium, and to the discharge section from the end on the upstream side of the recording medium, and therefore the effect of suppressing deformation of the recording medium during discharge from the discharge section can be improved. Further, since the air blowing is stopped as the upstream end of the recording medium is discharged from the discharge portion, unnecessary air blowing that would interfere with the loading of the recording medium onto the discharge tray can be suppressed.

A recording apparatus according to a fifteenth aspect of the present invention is the recording apparatus of any one of the first to fourteenth aspects, wherein the first air blowing unit and the second air blowing unit are disposed vertically above an upper limit of a loading height of the recording medium loaded on the discharge tray.

According to this aspect, since the first air blowing unit and the second air blowing unit are disposed vertically above the upper limit of the loading height of the recording medium loaded on the discharge tray, the deformation of the recording medium can be suppressed even when the loading height of the recording medium reaches the upper limit.

A sixteenth aspect of the present invention is directed to the recording apparatus of any one of the first to fifteenth aspects, wherein the control unit changes the blowing directions of the first blowing unit and the second blowing unit according to a length of the recording medium discharged to the discharge tray in the discharge direction.

According to this aspect, since the first and second blowing sections change the blowing direction in accordance with the length of the recording medium discharged to the discharge tray in the discharge direction, the deformation of the recording medium can be appropriately suppressed in accordance with the length of the recording medium to be used in the discharge direction.

A recording apparatus according to a seventeenth aspect of the present invention is the recording apparatus according to the sixteenth aspect, wherein the controller causes the first and second air blowing units to change an air blowing direction so as to follow a position of the downstream end of the recording medium discharged to the discharge tray.

According to this aspect, the first air blowing unit and the second air blowing unit change the air blowing direction in accordance with the position of the downstream end of the recording medium discharged to the discharge tray, and therefore, it is possible to suppress especially deformation of the downstream end of the recording medium.

Hereinafter, a recording apparatus 1 according to an embodiment of the present invention will be described in detail with reference to the drawings. In the following, an ink jet printer is exemplified as an example of the recording apparatus 1 of the present invention.
