Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera structure applied to a rear confirmation camera for a vehicle and attached to the outside, and more particularly to a camera structure having an improved camera body.

[0002]

2. Description of the Related Art In a conventional camera structure of this type, a camera body 30 has a lens section 3 which is an image reading apparatus using a solid-state image pickup device such as a CCD device as shown in FIGS.
1, an iris motor 32, an iris cover 33, a lens holder 34, and a substrate 35. The lens portion 31, the iris motor 32, and the iris cover 33 of the camera body 30 are connected to each other and integrated,
These form the lens unit A.

On the front surface of the lens holder 34, a lens unit mounting portion 36 and a boss mounting portion 3 which is positioned on the left and right sides sandwiching the lens unit mounting portion 36.
7, 38 are formed. Since the lens unit 31, the iris motor 32, and the iris cover 33 are integrated, the lens unit A is attached to the lens unit mounting unit 36.
For mounting the lens unit A, the lens unit A is inserted into the lens unit mounting portion 36 from the optical axis direction (immediately above the lens holder 34).

Therefore, the lens holder 34 is
The lens unit A is designed so as to avoid the portion into which the lens unit A is inserted, and the left boss mounting portion 37 is arranged so as to protrude outside while avoiding the lens unit mounting portion 36.

[0005]

As described above, in the camera body 30 having the conventional camera structure, the lens holder 34 is designed so as to avoid the portion into which the lens unit A is inserted, and the left boss mounting portion. Since 37 is arranged so as to project to the outside, the outer dimension L2 of the camera body 30 becomes large, and there is a problem that the overall structure is made smaller and lighter.

The present invention has been made in view of the above problems, and an object of the present invention is to enable downsizing and weight reduction of a camera body, and downsizing of the entire structure.
It is to provide a camera structure that enables weight reduction.

[0007]

In order to achieve the above-mentioned object, the present invention comprises a camera body, which is composed of a lens holder and a lens unit mounted on the lens holder, and a lens unit mounting portion is mounted on the lens holder. To form
The lens holder is provided with boss mounting parts that are located on the left and right sides of the lens unit mounting part, and one boss mounting part is provided on the end of the boss holding arm that rises from the peripheral surface of the lens holder. The lens unit mounting portion, the lens unit mounting portion is positioned in front of the lens unit mounting portion, the protruding portion of the lens unit is avoided from the boss holding arm, and the lens unit is inserted into the lens unit mounting portion. The lens unit is mounted on the lens unit mounting portion with the protruding portion positioned behind the boss mounting portion. It is preferable that the lens unit includes a lens portion, an iris motor, and an iris cover, and the protruding portion of the lens unit includes the iris motor and the iris cover.

[0008]

With this structure, the boss mounting portion of the boss holding arm is located in front of the projecting portion of the lens unit, and the boss mounting portion of the boss holding arm does not protrude outside the projecting portion of the lens unit. Therefore, the outer dimension of the lens body is smaller than the dimension in the outer direction of the lens body in the conventional camera structure, and the camera body can be made smaller and lighter, and the entire structure can be made smaller and lighter. To do.
