DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waterproof structure for a camera.

[0002]

2. Description of the Related Art Conventionally, as shown in Japanese Utility Model Laid-Open Publication No. 61-50946, a waterproof camera window structure has a camera lens window formed on the front of a front cover which is divided into front and rear portions. The protective optical member and the Fresnel member are insert-molded into the window for the objective section and the flash emission section, and the counter window on the top of the front cover is coated with the double-sided tape on the inside and outside of the transparent member. The windows of the waterproof camera that adhered the windows had a waterproof structure.

[0003]

However, in the waterproof structure in which the cover forming the outer periphery of the camera can be vertically divided and opened and closed and the packing member of the divided portion is charged in the radial direction, the insert having the window waterproof structure is used. In molding, it is difficult to insert-mold the window member in a plane perpendicular to the drawing direction inside the cover. Further, in the waterproof structure using the double-sided tape, the inside and outside windows are required, and the number of parts of the window member increases.

Further, in this structure, as shown in FIG.
The packing member 41 is charged in the radial direction by a packing charge portion 39a of the upper cover 39 and a packing charge portion 40a of the lower cover 40. However, if the thickness of the upper cover 39 is not sufficiently increased to secure rigidity, the upper cover 39 is not provided.
Is bent outside of the camera due to the elasticity of the packing 41,
The charging power of the packing is lost, and the waterproof function is not achieved.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and does not increase the number of parts of the window member, does not lose the charging force of the packing, and furthermore, distorts the camera cover outside. It is another object of the present invention to provide a waterproof camera that does not have a sufficient waterproof function.

[0006]

In order to achieve the above-mentioned object, according to the first aspect of the present invention, a cover forming an outer periphery of a camera can be vertically divided and opened and closed, and a packing member of the divided portion is formed. In the waterproof camera to be charged in the radial direction, the front opening and the rear side of the upper cover, the substantially rectangular opening of the cover, the long side of the opening for the photographing lens window and the window opening for the liquid crystal display window, etc. are waterproofed. And at least one member of each of the plurality of members has a length of about half of the long side of the cover opening on each surface, and this member is provided on each of the upper cover front side and the rear side. The waterproof camera according to claim 1, wherein the waterproof camera is configured to be fixed to the surface from outside.
In each of the members, a plurality of windows are integrally formed.

With these configurations, the cover thickness can be reduced by increasing the rigidity of the cover and suppressing the deformation of the cover due to the elastic force of the packing of the cover.

A rear member in which the portion 33b is integrated, a packing member 34 charged by the liquid crystal display window 23d and the window 33a on the rear surface of the upper cover 23, and a finder eyepiece window 23e of the upper cover 23
And a packing member charged by the window 33b, 3
Reference numeral 6 denotes a screw for fixing the rear member 33 to the upper cover 23, and reference numeral 37 denotes an engaging member that engages with the claw portion 24a of the lower cover 24, and is always urged in a direction to engage with the claw portion 24a. Reference numeral 38 denotes a knob member that is interlocked with the engagement member 37 by an interlock mechanism (not shown).

In the above configuration, the lower cover 24
Is closed, the engaging member 37 is engaged with the claw portion 24a. When the knob member 38 is rotated from this state, the engaging member 37 interlocking with the knob member 38 comes off the claw portion 24a of the lower cover 24 while resisting the bias. At this time, the packing member 26 includes a packing charge portion 23f of the upper cover 23 and a packing charge portion 24b of the lower cover 24.

3, the waterproof structure of the windows on the front side and the rear side of the upper cover 23 makes it possible to secure the rigidity of the front side and the rear side (the long side of the opening) of the upper cover 23. The deflection of the front side and the rear side of the upper cover 23 is suppressed.

[0014]

As described above, in each of the inventions described in the claims of the present application, the cover forming the outer periphery of the camera can be divided vertically and can be opened and closed, and the packing member of the divided portion is charged in the radial direction and used. In the waterproof structure, when the windows (for the photographing lens window and the liquid crystal display window) on the front side and the rear side of the upper cover (the longer side of the substantially rectangular opening of the cover) are made waterproof, the front and rear for waterproofing are used. By making at least one member of each of the surface components approximately half the length of its long side and fixing it to the upper cover in the long side direction from the outside, rigidity in the long side direction of the upper cover can be secured. In addition, it is not necessary to increase the thickness of the cover in order to secure rigidity, and the weight of the camera can be reduced.
