Field of the Invention The present invention relates to a waterproof structure for a rotary operation section of a camera, and more particularly to an improvement of a waterproof structure for a rotary operation section of a camera, which has both operability and waterproofness.

Description of the Related Art Usually, a rotation operating member for switching modes such as hoisting and rewinding is provided on an exterior member of a camera, for example, an upper lid, and a mounting member for inserting a rotation transmitting portion of the rotation operating member. A hole is drilled in the top lid.
Since there is always a gap in the camera body due to the mounting hole provided on this type of lid, water droplets etc. may enter the camera through this gap and cause electrical system and mechanical system failures inside the camera. Become.

In the technical means disclosed in 7-88121, a viscoelastic material such as rubber is used for the mounting seat to obtain waterproofness, and a sliding washer made of a resin material having a low friction coefficient is used as the viscoelastic material and the operating member. It is designed to secure the slidability of the rotary operation part by being clamped by.

いる。このように、部品が１点でも多いことは、カメラ

かりでなく、製造時の組立作業が増えるなどマイナス要
因となる。By the way, the waterproof structure in the rotary operation portion of the camera disclosed in Japanese Utility Model Laid-Open No. 57-88121 is constructed by two parts of viscoelastic material such as rubber and low friction coefficient resin material. It has a structure that is approved for the first time. As described above, the fact that the number of parts is even one is a negative factor in that not only the proportion of the cost of parts and materials in the configuration cost of the camera rises, but also the assembly work during manufacturing increases.

化させないために挟持する力を弱くすると、今度は密封
度が低下してしまい、本来の目的である防水効果が劣化
することになってしまう。However, if one of these two parts is used to form the waterproof structure, a problem will occur. That is, when only a viscoelastic material is used, the elasticity of the material is used to seal the gap between the rotary operation member and the exterior member, so that the viscous resistance of the material increases the force for rotating the rotary operation unit, resulting in an increase in operability. Significantly deteriorates. On the other hand, when only the sliding washer is used, it does not have the elasticity of a viscoelastic material, so it is necessary to clamp it more firmly to ensure the sealing property between the rotary operation part and the exterior. Remarkably deteriorates the operability of the operation part. Therefore, if the clamping force is weakened in order not to deteriorate the operability, then the degree of sealing will be reduced, and the original waterproof effect will be deteriorated.

必要とする。Further, when the viscoelastic material is adhered and fixed in the mounting hole of the camera body as in the conventional case, this adhering work is required for assembly. Furthermore, when this part deteriorates, it is necessary to remove the adhered viscoelastic material at the time of replacement, and there is a risk of damaging the exterior of the camera. In addition to this, in order to achieve both waterproofness and operability, it is necessary to accurately adjust the sandwiching force between the viscoelastic material and the resin material having a low coefficient of friction when attaching the rotary operation member. It is necessary to design the clamping method and maintain the part processing accuracy while taking into account variations in accuracy.

The screw ring 9 is screwed on. This cam 5 is provided with an oval hole so as to follow the mode dial 1a. Further, the cam 5 is provided with several grooves for stopping the mode dial 1a at a predetermined position, and the spring 6 is provided with the exterior member 2a so that the convex portion of the mode dial 1a may jump into the grooves.

By inserting only one washer made of an elastic porous PTFE sheet between the exterior member and the exterior member 2a, a waterproof structure having both operability and waterproofness can be obtained. This washer 3a is made of PTFE having elasticity as described above.
This is a sheet, which is a material that has been widely used as a fixed seal material for flange joints in the piping system of large plants, and was limited to use in the fixed part.
Therefore, although the water repellency and elasticity of PTFE have been utilized, the low coefficient of friction has not been utilized. The present invention pays attention to this point, and by sandwiching the washer 3a between the mode dial 1a and the exterior member 2a, the elasticity of the washer 3a keeps the gap between the mode dial 1a and the exterior member 2a in a stopped state and also in a rotating state. At the same time as obtaining the effect, the property as a low friction coefficient material is utilized to improve the operation performance during rotation.

が少ないことで自由度も高まる。Since the washer 3a is attached to the mode dial 1a by its elasticity, the bonding work is not necessary. Therefore, even if the washer 3a needs to be replaced,
Since it is not adhered, it is not necessary to forcibly remove it, so that there is no risk of damaging the mode dial 1a. Also, 1
Since it is a component, the structure is simplified and the assembling work is facilitated, which leads to a reduction in assembly time and a reduction in assembly mistakes, and thus has an effect of cost reduction. Further, the amount of force that holds the washer 3a between the mode dial 1a and the exterior member 2a changes only by the dimensional tolerance of the washer 3a, and the waterproof effect can be obtained without finely adjusting the holding force.
High precision is not required for the design of the rotary operation part, and the flexibility is increased due to the small number of parts.

である。It is not necessary to finely adjust the clamping force in this way, because when the clamping force becomes strong due to variations in the dimensional accuracy of the parts, the operability is not impaired by the low friction coefficient of PTFE. On the contrary, the waterproof effect is maintained by the water repellency of PTFE even when the holding force is weakened.

In the embodiment shown in FIG. 2 above, the washer 3a made of an elastic porous PTFE sheet is held between the mode dial 1a as a rotary operation member and the exterior member 2a of the camera body, and the cam 5 is pushed up by the screw ring 9. I was doing it. On the other hand, in this modification,
