PROBLEM TO BE SOLVED: To realize the reduction of cost by alternatively switching the movement of a lens, the normal rotation of a developing roller and the reverse rotation of the developing roller by utilizing a single motor. SOLUTION: A driving system is constituted of a lens driving transmission system 41, a roller driving transmission system 42 and a driving switching mechanism 44. The system 41 transmits the rotational driving to a lens moving mechanism for circularly moving a moving barrel holding a photographing lens between a collapsing position and a photographing position. The system 42 transmits the rotational driving to a pair of developing rollers 27. The mechanism 44 is switched to a position where the driving in a normal rotation direction by a motor 40 is transmitted to the system 41 when such driving is transmitted, and switched to a roller driving system transmission position where the driving in a reverse rotation direction by the motor 40 is transmitted to the system 42 when such driving is transmitted. When a cleaning button 51 is pressed for operation, the mechanism 44 is switched to the roller driving system transmission position regardless of the direction of the driving transmitted from the motor 40, and a switch member 52 is turned on so that the motor 40 is driven to rotate normally by a control part 56.
