In the present embodiment, continuous unevenness is used as the anti-slip means 125.

The outer portion 200 is made of an elastic material. As the elastic material, an elastomer having rubber elasticity is used. Specifically, Super Tribrene (trade name) HD140 manufactured by Shinko Kasei Co., Ltd.
Cosmogel (trade name) HC04 manufactured by Cosmo Keiki Co., Ltd., with a composition of 70% by weight and molded at about 230 ° C. is used. The outer portion 200 is closely attached to the second main body 120 so as to cover the entire outer surface of the second main body 120 and the open end of the opening 121 (see FIGS. 1 to 4). The close contact between the outer portion 200 and the second main body 120 can be easily performed by forming the two portions in two colors. Therefore, the outer portion 200
It covers the outside of the weakened portion 200 and is closely attached to the cover main body 100 around the weakened portion 200. The outer portion 200 is extended to a contact portion between the first main body 110 and the second main body 120.

Next, a method of using the waterproof camera will be described.

First, to wind up the film, the lever 123 of the second main body 120 is rotated counterclockwise in FIG. Then, a pulling force is applied to the outer portion 200 at the portion corresponding to the wide cutout portion 122a via the lever portion 123. In this part, the outer part 20
Since 0 is not in close contact with the second main body 120, it can be easily extended according to the pulling force. Then, the lever portion 123 can rotate around the narrow notch portion 122b as a fulcrum. Then, the non-slip means 125 formed on the inner surface of the second main body 120 comes into contact with the film winding means 13, and the film winding means 13 can be rotated. Subsequently, when the force applied to the lever portion 123 is loosened, the lever portion 123 returns to the initial position by the elastic force of the outer portion 200. Then, when the lever is operated in the same manner as described above, the film winding means 13 can be further rotated. Thus, the film can be wound up.

Then, by pressing down the shutter from above the cover 20, the camera can be used in the same manner as a normal camera.

In the waterproof camera of this embodiment, the cover 20
Provided with the weakened portion 122 and the outer portion 200 in the cover 2
There is an advantage that the film can be easily wound by appropriately deforming 0.

In the waterproof camera according to the present embodiment, since the weakened portion 122 is completely covered by the outer portion 200, the cover 2 is separated from the weakened portion 122 by the outer portion 200.
0 can be prevented from infiltrating into the camera body 1
0 can be made waterproof.

Further, in the waterproof camera of the present embodiment, the cover body 100 is divided into the first body 110 and the second body 120, so that the camera body 10 is inserted into both of them and the openings 111 and 121 of each other. The camera main body 10 can be sealed inside the cover main body 100 only by fitting the camera body with the camera body, and there is also an advantage that the manufacturing operation is simple.

Further, in the waterproof camera of this embodiment, the outer portion 200 made of an elastic material is connected to the first main body 110 and the second main body 110.
Since the outer portion 200 is extended to the contact portion with the main body 120, the outer portion 200 can be interposed between the two, and the sealing effect of the outer portion 200 can improve the waterproof effect on the camera main body 10.

The amount of rotation of the film winding means 13 per one rotation can be increased. In the narrow notch 122b, the rotation fulcrum can be made substantially constant because the width is narrow. Therefore, with these configurations, the film winding operation can be performed more easily.

The waterproof camera according to the present embodiment has the following advantages because the side ribs 112 and the front ribs 113 are provided. That is, in general, in a resin molded product, the molded product is slightly inclined in consideration of the ease of removal from the mold after molding. For example, referring to the shape in FIG. 5, it is tapered so as to gradually and slightly spread from the right end to the left end (almost no appearance in the figure). In this situation, the camera body 10 is
When arranged parallel to the central axis of the main body 120 (horizontal line in FIG. 5), the lens 11 of the camera main body 10
The second main body 120 is slightly inclined. Then, the light that reaches the lens 11 through the second main body 120 is
There is a disadvantage that the image is unnaturally distorted by the second main body 120 and the image is distorted. On the other hand, in the waterproof camera of the present embodiment, the camera body 10 can be supported in an inclined state by the side ribs 112 and the front ribs 113, so that the lens 11 and the front surface of the second body 120 are substantially parallel. (When the lens is spherical, it is assumed that the lens is flat and parallel), so that the distortion of the obtained image can be reduced and the image quality can be improved.

The waterproof camera of the present embodiment has the following advantages since the front rib 113 is provided on the inner surface of the cover body 100. That is, when the strobe 15 emits light, if there is no front rib 113, light from the strobe is reflected by the inner surface of the cover body 100, and a part of the light may enter the lens 11. Then, the quality of the image obtained through the lens 11 may be degraded. In the present embodiment, since the front rib 113 is formed between the lens 11 and the strobe 15, light from the strobe can be blocked by the front rib 113, and therefore, it is possible to improve the quality of a photograph. Become.

Further, in this embodiment, since the relief portion 122c is formed in the weakened portion 122, when the shutter is pressed,
By simply pushing down the soft outer portion 200, the shutter can be pushed without being hindered by the hard cover body 100. Therefore, there is an advantage that operability as a camera is improved.

In this embodiment, the weakening section 12
Although 2 is constituted by a notch, it is not limited to this. The point is that the strength may be reduced so as to allow the rotation of the cover body 100 as described above.

In the present embodiment, the narrow cutout portion 122b is provided.
For example, a U-shaped or V-shaped groove may be formed on the inner surface of the second main body 120 along the up-down direction. By doing so, the rotation fulcrum is further fixed, so that improvement in operability can be expected.

Further, in the present embodiment, the side rib 112
Although the camera main body 10 is configured to be inclined and held by the front rib 113 and the front rib 113, the present invention is not limited to this. In other words, if a holding unit for holding the camera main body 10 is provided, It is good that distortion can be reduced.
