PURPOSE:To make the transmission of release signals sure by providing only one transmission system for release signals and constituting the transmission system in such a way that said system is operated by either of a blind feed signal or a rewinding signal. CONSTITUTION:Means of counting the rate of winding of a film 55 and generating a blind feed signal unit said rate attains a prescribed value are constituted of a counter 36, a shaft 41, a cam 43, etc. Means of generating the rewinding signal of the film 55 are constituted of a button 211, a sprocket 84, a circular conical part 214, a selection lever 215, etc. Further the transmission means for transmitting a release signal from a motor 30 to a photographing mechanism are constituted of gears 113, 115, 17 and a cam 16. The transmission system is so arranged as to be connected or disconnected when the connecting and disconnecting means consisting of a lever 13, a shaft 15, etc. are operated by either of the blind feed signal or the rewinding signal. |
