Abstract
A rotary plate has an eccentric shaft and a recessed portion which are spaced from a rotary shaft. A shutter is connected to the eccentric shaft by a swing arm which is rotatable about the eccentric shaft. A pin is provided on the swing arm. When the rotary plate starts rotating from a closed condition of the shutter, the swing arm moves linearly to release the shutter even when the shutter freezes to the casing. When the swing arm further rotates, the pin engages with the recessed portion of the rotary plate. The swing arm is integrated with the rotary plate. The shutter is quickly opened. When the shutter is fully opened, the pin disengages from the recessed portion. As the eccentric shaft is located adjacent to the rotary shaft, a large force is transmitted to the shutter. Thus, it becomes possible to use a low-power motor to release the shutter from the camera casing even when they freeze together.
