Abstract

PURPOSE:To rewind a film up to its leader part by electrically conducting to a motor continuously by detecting the film leader part by a counter during rewinding operation in a camera wherein the film is all taken up and then rewound on every shot. CONSTITUTION:In a preliminary winding type motor camera wherein a film drawn out of a cartridge is rewound, frame by frame, over photographing, a counter goes down during rewinding operation. Once the counter indicates 0, a switch SWs is closed and on exposure, a winding end switch SWw is closed. With a mode switch SWc turned off, a gate NOR holds itself at a level L in response to the inverted output of the counter COT and a final-winding inhibition signal having a level H to energize a relay RL1, permitting a motor M to turn normally and continuously. Namely, the film leader part is rewound without reference to a release signal, thus completing all operations regarding the film.
