Abstract

PURPOSE:To prevent malfunction of a camera, by avoiding the operation of a magnet for shutter opening, if a trigger switch is not set to an operationable prescribed state. CONSTITUTION:In the operation of release, if a trigger switch TG is not in an operationable initial state, since the trigger switch TG is turned off, even if a release switch S2 turns on with a winding up switch WE turned on, a switch signal output circuit GC does not output a release signal to a control circuit SC. Thus, the control circuit SC does not turn on shutter opening magnets beta and alpha with a driving circuit DR, does not output a sequence end signal, and does not keep on-state by grounding the base of a transistor T2. That is, no exposure sequence is made. Thus, the malfunction of a camera can be prevented.
