Abstract
A winding and rewinding apparatus for a camera comprises a winding mechanism, a detector, a rewinding mechanism, a selector and a controller. The winding mechanism winds the film frame by frame, and the detector detects the completion of exposure of the roll of film which is wound by the winding mechanism. The rewinding mechanism rewinds the film automatically in response to the detection of the detecting means. The selector includes a selecting switch which is operable manually, for selecting in response to the operation of the selecting switch one of a first mode in which the operation of the rewinding mechanism is permitted and a second mode in which the operation of the rewinding mechanism is inhibited irrespective of the detection of the detector. The controller controls the rewinding mechanism in accordance with the mode selected by the selecting switch. According to such arrangement, the user can select a manual rewinding mode or an automatic rewinding mode by a simple operation.
