Abstract:
PURPOSE: To prevent a shutter chance from being lost by enabling shutter releasing operation in the case the power source battery of a camera is deteriorated and feeding film becomes impossible but the shutter releasing operation is possible.
CONSTITUTION: Whether or not the voltage of a secondary battery 2 in which electricity of a solar battery 1 is accumulated exceeds voltage required for performing the shutter releasing operation is compared in a comparator 10. In the case it is high enough to perform the shutter releasing operation but it is lower than the voltage required for feeding the film, which is compared in the comparator 11, only a shutter driving part 18 is operated.
