Description

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 battery cover of a drip-proof waterproof camera.

[0002]

2. Description of the Related Art Conventionally, a so-called drip-proof type is provided in which a sealing member such as an O-ring is provided on the back cover or the outer peripheral portion of the back surface of the camera body to prevent water from entering from the outside of the camera and to be usable underwater. Waterproof cameras are known. FIG. 4 is a sectional view showing a conventionally known waterproof camera, and FIG. 5 is a partially enlarged sectional view showing a battery cover of the camera.

In the conventional waterproof camera 1, as shown in FIGS. 4 and 5, the elasticity of the seal wall 2a of the outer box 2 and the elasticity of the back cover O-ring 4 mounted in the seal member mounting groove 3a of the back cover 3. It was sealed by the close contact by the repulsive force. Further, a waterproof glass 20 was provided on the front surface of the outer box 2, and a lens O-ring 21 was also mounted between the outer box 2 and the waterproof glass 20. The waterproof seal portion prevents water from entering the inside and protects the camera mechanism portion 5 and the photographing lens 22 housed in the outer box from water.

The camera mechanism 5 has a battery lid 31.
A battery compartment 6 which is partitioned from the outside by a means, a film chamber 7 for accommodating a film cartridge, a spool 8 for winding up a film after photographing, a film chamber and the spool for covering the photographing film from the outside. An inner lid 15 is provided.

[0005]

However, although this type of waterproof camera can prevent water from entering the inside when it is used in water, it requires replacement of the film or battery after use in water. It occurs and the user needs to open the back cover 3. At this time, water droplets adhering to the seal member mounting groove 3a and the back lid O-ring 4 drop into the outer box 2 and stay on the cover 9, and then from the gap between the battery lid 31 and the camera mechanism portion 5 to the inside. There were problems such as penetration to reach the battery housing 6 and short-circuiting the battery 14 and corrosion of the battery contacts 16 and the like in the battery housing 32.

[0006] In view of the above problems, the applicant of the present invention filed Japanese Patent Application No.
No. 32315 has been filed, but it may not be possible in some cases due to space problems inside the outer box. Therefore, in view of the above problems, the present invention prevents the water droplets dripping inside the outer box from entering the battery housing part of the waterproof camera inside the outer box even when the back cover of the outer box is opened. The purpose is to

[0007]

To achieve the above object, the present invention provides an outer box (2) having an opening, a lid member (3) for closing the opening, and an inside of the outer box. The camera mechanism part (5) housed and supported in the above, and the lid member (3) or the outer box (2) are disposed, and when the lid member (3) closes the opening, In a drip-proof waterproof camera including a seal member (4) for sealing a camera mechanism section (5), the camera mechanism section (5) allows a battery (14) to be housed therein, and the battery is inserted therein. A battery housing (6) having a battery opening for storing the battery, and a battery lid (11) for arranging an elastic member (12) on the outer periphery to open and close the battery opening. When the battery cover (11) is closed, the battery opening is sealed by the elastic member (12). It was constructed as that.

[0008]

According to the above construction, when the user takes a picture in water and then exchanges the film or the battery, water drops attached to the seal member mounting groove or the O-ring are put in the outer box 2. Even if dropped, it is blocked by the elastic member (12) arranged on the outer peripheral portion of the battery lid (11) and does not intervene in the gap between the battery lid (11) and the camera mechanism section (5). It does not enter the storage section (6) either.

[0009]

1 is a sectional view showing a waterproof camera according to the present invention, and FIG. 2 is a partially enlarged sectional view showing a battery lid portion of the camera. FIG. 3 is a perspective view of the waterproof camera seen from the rear with the back cover open. A battery cover rubber 12 is provided over substantially the entire outer peripheral edge of the battery cover 11.

The battery lid rubber 12 and the battery lid 11 are fixed to each other by a method such as adhesion with an adhesive. The fixing portion 11a between the battery lid rubber 12 and the battery lid 11 is a battery housing portion from the outside of the camera mechanism 15. 6 has a structure in which water droplets do not enter. In this embodiment, the adhesive is used for fixing, but other techniques such as double molding and vulcanization adhesion are also applicable.

Further, the battery lid rubber 12 is formed of a viscoelastic material, and in the state where it is fixed to the battery lid as described above, the outer peripheral portion thereof is substantially the same as the battery housing opening portion 6a or the opening portion of the battery housing portion opening portion 6a. Is also a large size shape. Next, the operation of this embodiment will be described. When the user uses the camera in water and opens the back cover 3 for film replacement or battery replacement, the seal member mounting groove 3a and the O-ring 4 are provided.
The water droplets that have adhered to the water drop inside the outer box 2 and the water is sealed to the seal wall 2a.
The water is accumulated on the cover 9 in the form of water droplets. Further, the water droplets move on the cover 9 and the battery lid 11 when an external force such as vibration is applied.

Here, when the battery 14 is inserted into the battery housing portion 6, the battery lid 11 is in a closed state,
It is locked to the camera mechanism section 5 by a known means. At this time, the battery cover rubber 12 is compressed and the boundary 12
The battery housing 6 is sealed from the outside by contacting the battery housing opening 6a at a. For this reason, even if water droplets move on the battery lid 11, the sealing effect of the battery lid rubber 12 prevents the water droplets from entering the inside of the battery housing portion 6.

[0013]

As described above, according to the present invention, even if the user uses the camera underwater to open the back cover for film exchange or battery exchange, and water droplets drop inside the outer box, From the gap of the camera mechanism part, it penetrates into the inside and reaches the battery compartment,
It is possible to prevent short-circuiting of the battery and corrosion of the battery contact or the like in the battery housing.
