Abstract
PURPOSE:To prevent malfunction at the film loading by controlling a change-over operating member by way of a back cover sensing member to automatically reset it to a rewinding state and interrupting the revolution transmission between a driving source and a rewinding shaft when the back cover is opened. CONSTITUTION:Breaking of a switch 12 by a change-over operating member 1 interlocking to a driving knob 2, controlling of a clutch 28 transmitting the driving force of a motor 8 to a rewinding shaft 7 by means of a rotor 10 integral with the member 1 and a clutch pin 9, etc. are accomplished and the film rewinding after photographing of the entire length of the film is accomplished by the easy operation upon stopping of the winding of the film. Thence, when a back cover 22 is opened, a back over sensing member 20 turns, and the member 1 disengaged from the pin 18 of the detaining member 17 turning cooperatively with said member is moved by the elastic force of a spring 5 and is reset to the winding state. At the same time, the clutch 28 is changed over by the pin 18 of the member 17, whereby the transmission of the driving force to the rewinding shaft 7 is interrupted. Hence, even if the user makes wrong operation at the film loading, the rewinding takes place but the occurrence of winding-in of the film and the like is prevented.
