Abstract

PURPOSE:To save electric power and to improve the safety of operation in a camera wherein a film is wound preliminarily and then rewound in a patrone on every shot. CONSTITUTION:To the base of a transistor TR0 in a power source circuit, a WE switch SWw which turns off by winding one-frame, a mode switch SWc turning on by film loading and back-cover closure and turning off on preliminary winding, a photometric switch SWD turning on when a release button is depressed by one stage, and a timer TM2 turning on the power source circuit for 60 seconds after the photometric switch turns off are connected. Therefore, electricity feeding is stopped except during one-frame winding, preliminary winding and release-button depression to save power batteries and to prevent malfunction.
