Abstract: An input device for zooming and shutter releasing includes a shutter release button; a pressing protrusion; a tact switch located on a substrate and configured to be pressed when the shutter release button is pressed downward; a rotary member rotatably supported at the periphery of the shutter release button; a magnet configured to be rotated in association with rotation of the rotary member, the magnet having a through hole at the center thereof, the pressing protrusion supported to extend through the through hole; and a magnetic sensor located at a position to face the through hole in the height direction and configured to detect a rotational magnetic field that is generated by the magnet because of the rotation of the rotary member, the tact switch and the magnetic sensor arranged side by side on the substrate.

Abstract: An upper radiating layer is formed around a lower core layer without making contact with the lower core layer, and each of first and second coils has a portion facing the lower core layer and a portion facing the upper radiating layer so that heat of the first and second coils is released to the upper radiating layer.

Abstract: An arrangement structure of optical elements is characterized in that light emitting and/or light receiving optical elements are mounted on a substrate in a zigzag fashion, whereby the resolving power of the arrangement can be enhanced.
