Abstract

PURPOSE:To feed a film by constant length with simple constitution by providing an information member, which reports the winding extent of a film, to a body of revolution which rotating in engagement with the winding operation of the film. CONSTITUTION:Once photographing operation ends, a motor 30 is driven. According to the drive of this motor 30, a take-up shaft 25 rotates to rotate a take-up drum 23. Therefore, a film 22 engaged with the drum 23 is wound. According to the winding of this film 22, a roller 36 coupling with it by friction also rotates and a reflecting plate fitted to the reverse surface of the roller 36 also rotates. When the reflecting plate reaches a position facing to the detection hole 38 of a bottom cover 20, light from a light emitting element 40 is reflected by the reflecting plate to strike a photodetecting element 41. According to this incidence, the element 41 outputs a pulse signal to a pulse counter circuit 34, which every time one pulse signal is inputted, outputs a stop signal to a motor controlling part 33. On receiving the stop signal, the controlling part 33 stops driving the motor 30.
