PURPOSE:To switch selectively the driving force of a motor to three driving systems with a simple mechanism by using a switch which starts the motor for the purpose of feeding a film, and a switch which starts the motor for the purpose of performing the other operations in common. CONSTITUTION:The contact piece 103 of the switch 100 of an electric circuit which rotates reversely the motor is depressed to be separated from a contact piece 101 and is brought into contact with a contact piece 102 temporarily and is brought into contact with the contact piece 101 again to hold the electric circuit of reverse rotation; and when a prescribed operation is terminated, the electric circuit is cut off by a signal accompanied with this termination to stop the motor. When an operation button 110 is depressed, the switch 100 is operated to start the reverse rotation of the motor, and therefore, the first clutch lever 15 is disengaged from a reel gear G1 and is rotated counterclockwise more than the case of lens moving thereafter to engage a planetary gear 17 with a rewinding gear 31, and the rewinding gear 31 is rotated counterclockwise. Thus, the operations of the camera other than film feeding are performed with the force of the motor by the simple mechanism and the film operation.
