PURPOSE:To realize a compact and low-priced drive mechanism by providing a witching mechanism composed of one drive source, a planetary gear for driving and switching, a clutch gear, a clutch solenoid and so on and switching and driving three drive systems. CONSTITUTION:Before the device starts its operation, a cam gear 26 stays at an upper dead point where a clamp arm 27 is fixed, and a keep pate 29 stays at an elevating position. As a motor 1 rotates counterclockwise, a planetary arm 4 turns clockwise due to the action of a friction spring and the planetary gear 5 meshes with a gear 6. Hence a pressurizing roller 10 rotates, and simultaneously a color developing sheet 44 and a pressure- and photo-sensitive recording sheet 19 are fed. When the motor 1 rotates clockwise, the planetary arm 4 rotates counterclockwise. The planetary gear 4 meshes with a gear 24, and the keep plate 29 goes down. When the clutch solenoid 33 is excited, the rotation of the motor 1 is transmitted to a pully gear 39, and exposure is executed by moving a lamp 41.
