Technical Field

One embodiment of the present invention relates to an imaging device and the like.

Background

Conventionally, there is an imaging device in which a lens barrel that holds a lens and a substrate on which an imaging element is mounted are housed in a case. In recent years, such an imaging device is increasingly mounted in an automobile, and in such a case, a waterproof seal member is sometimes disposed between a front case and a rear case constituting a case in order to improve the waterproof property. For example, patent documents 1 to 3 disclose conventional configurations of such a camera (imaging device) having a waterproof performance.

Disclosure of Invention

Problems to be solved by the invention

In recent years, further miniaturization has been demanded in the conventional imaging apparatus having a waterproof performance as described above, but there is a limit to miniaturization in the conventional configuration.

Means for solving the problems

In order to solve the above problems, the present invention adopts the following means. In the following description, reference numerals in the drawings and the like are shown in parentheses for easy understanding of the present invention, but the respective constituent elements of the present invention are not limited to these reference numerals and should be interpreted broadly to a level that can be understood by those skilled in the art.

One aspect of the present invention is an imaging apparatus including: a 1 st case (3, 31 or 7, 71); a 2 nd housing (7, 71 or 3, 31) coupled to the 1 st housing; substrates (51, 52) that are housed in an internal space formed by the 1 st case and the 2 nd case and on which electronic components are mounted; a lens barrel (1) that holds a lens and is supported by the 1 st housing or the 2 nd housing; and a waterproof seal (4) held in a waterproof seal holding space formed between the 1 st case and the 2 nd case, wherein the 1 st case has 1 st surfaces (3d, 71d) substantially perpendicular to an optical axis, 2 nd surfaces (3c, 71c) substantially parallel to the optical axis, and inner surfaces (3e, 71e) extending in the optical axis direction from the 1 st surface, the 1 st and 2 nd surfaces forming the waterproof seal holding space, the inner surfaces facing the end portions of the substrate, the 2 nd case has 3 rd surfaces (7d, 31d) substantially perpendicular to the optical axis and 4 th surfaces (7e, 31e) substantially parallel to the optical axis, and the 3 rd and 4 th surfaces forming the waterproof seal holding space.

Another aspect of the present invention is an imaging apparatus including: a 1 st case (3, 31, 32 or 7, 71, 72); a 2 nd housing (7, 71, 72, or 3, 31, 32) coupled to the 1 st housing; substrates (51, 52) that are housed in an internal space formed by the 1 st case and the 2 nd case and on which electronic components are mounted; a lens barrel (1) that holds a lens and is supported by the 1 st housing or the 2 nd housing; and a waterproof seal (4) held in a waterproof seal holding space formed between the 1 st case and the 2 nd case, the 1 st case having: a 1 st surface (32c, 3d, 71d) having a portion substantially perpendicular to the optical axis; and inner surfaces (32d, 3e, 71e) extending in the optical axis direction from the 1 st surface, the 1 st surface forming the waterproof seal holding space, the inner surfaces facing the end portions of the substrates, the 2 nd housing having a 3 rd surface (72d, 7d, 31d), the 3 rd surface having a portion substantially perpendicular to the optical axis, the 3 rd surface forming the waterproof seal holding space.

According to the imaging device of any of the above configurations, the inner surface facing the substrate is configured to extend outward of the housing as compared with the conventional configuration, and therefore, even when the housing has the same size as the conventional one, the space for disposing the substrate can be relatively large. Thus, when a structure using a substrate having the same size as that of the conventional one is adopted, the imaging device can be configured to be relatively small.

In the above imaging device, it is preferable that the 1 st housing is disposed at a position forward in the optical axis direction than the 2 nd housing, and the lens barrel is supported by the 1 st housing.

According to the image pickup apparatus configured as described above, the lens barrel is supported by the front housing (1 st housing) positioned forward in the optical axis direction, and a relatively large substrate arrangement region can be secured inside the front housing.

In the above imaging apparatus, it is preferable that the 1 st housing is disposed rearward in the optical axis direction than the 2 nd housing, and the lens barrel is supported by the 2 nd housing.

According to the image pickup apparatus configured as described above, the lens barrel is supported by the front housing (2 nd housing) positioned forward in the optical axis direction, and a relatively large substrate arrangement region can be secured inside the rear housing (1 st housing).

In the imaging device, it is preferable that the substrate has an imaging element mounted thereon.

According to the imaging device having the above configuration, it is possible to achieve a relatively small configuration and a relatively large configuration in which the space for disposing the substrate on which the imaging element is mounted is secured.

In the above imaging device, it is preferable that the imaging device further includes an imaging element substrate that is housed in the internal space and on which an imaging element is mounted.

In the imaging device, the inner surface preferably faces an end portion of the imaging element substrate.

According to the imaging device having the above configuration, the imaging device having the plurality of substrates can be configured to be relatively small, and the space for disposing the plurality of substrates can be relatively large.
