Abstract
PURPOSE:To eliminate troubles of the switching of the film advancing mode and the manual film advancing for film loading, by detecting the presence or the absence of a cartridge by a detecting lever to advance the film containuously for film loading and rewinding to the film frame by frame for no-film loading. CONSTITUTION:A sprocket 19, a spool 13, and a cartridge 35 are turnable through a prescribed gear row by a driving motor 1, and the presence or the adsence of the cartridge 35 is detected by a deteting lever 37 to switch prescribed switches. In this constitution, when the cartridge 35 is not loaded, the motor 1 is rotated clockwise by the shutter operation, and the cartridge 35 is turned in the rewinding direction frame by frame. When the cartidge 35 is loaded, the motor 1 is rotated counterclockwise through the detecting lever 37 to advance the spool 13 continuously. When the changeover knob 39 is set to a direction A after completion of advancing, said no-loading state is set, and the film is rewound frame by frame while photographing. Thus, troubles of the switching of the film advancing mode and the manual film advancing for film loading are eliminated.
