1. A camera device with a shutter button, the shutter button having an obverse face and a reverse face, for transmitting an externally-applied pressing force to a switch, the device comprising:
- a plate-like member including a flat portion disposed opposite to the reverse face of the shutter button,a coil spring disposed between the shutter button and the plate-like member and having a first winding portion and a second winding portion, the first winding portion being wound into a first shape about a central axis, the second winding portion being wound into a second shape about the central axis so as to include the first winding portion, anda boss portion provided on the reverse face of the shutter button, opposed to the switch, and inserted into the first winding portion and the second winding portion, wherein;
the flat portion of the plate-like member includes a hole for inserting the boss portion therein,the boss portion pushes the switch by way of the externally-applied pressing force transmitted through the shutter button in condition of being inserted in the hole of the flat portion,the first winding portion is provided so as to continue from one end of the second winding portion,the first winding portion and a winding of the second winding portion that continues therefrom are positioned roughly on a same plane at an end of the coil spring,ends of the second winding portion are in contact with the shutter button and the flat portion, respectively,the second winding portion has a larger diameter about the central axis than the first winding portion,the first winding portion is positioned proximal to the shutter button, andthe second winding portion has substantially the same diameter along its entire length, and its length is substantially equal to that of the coil spring.
