Abstract
PURPOSE:To realize the convenience for snapping in an emergency or the photographing just for a specific number of frames, by carrying out the switching from the continuous winding mode to the rewinding mode at an optional position in addition to the automatic switching which is carried out when the continuous winding is over. CONSTITUTION:A film is continuously wound from a film container to a spool chamber prior to photographing, and then the photographing is carried out while rewinding the film to the film container by a frame. With such a motor-driven camera, a continuous winding end detecting means detects the change of torque when the continuous winding is over and moves a torque detecting lever 78 on a patrone detecting lever 76. As a result, the automatic switching is possible by a switching contact bar 79 between the winding mode and the rewinding mode. In case the continuous winding is discontinued at a point when a specific number of frames is wound, a push-button 82 is pushed to move the lever 78 to the left side to perform the switching.
