发明名称 Camera film feed control apparatus
摘要 A film feed control apparatus generates an output signal for instructing the rewinding of the film when a wind operation for a frame of a film is stopped before it is completed and the number of exposed frames has exceeded a nominal number of exposures. The film feed control apparatus stops the power supply to a wind motor when the wind operation is stopped before the number of exposed frames reaches the nominal number of exposures.
