Abstract

PURPOSE:To achieve the photographing operation of a camera, wherein a film is all wound first and then rewound in a cartridge on every shot, by releasing all proof members without a film loaded. CONSTITUTION:A mode switch SWc turns on with film loading and back-cover closure and turns off with film unloading, back-cover opening, and preliminary winding operation completion. A counter switch SWs turns on only when a film is loaded and a counter indicates an E (End: start of ordinary camera). Therefore, when no film is loaded, a film advance type motor never operates and a gate AND2 generates an H-level output except during release operation and before one-frame winding completion, so that the H-level signal is inputted to an AE circuit with a release switch closed.
