PURPOSE:To improve the reliability of a photosensitive body by processing said body by an electrical operation. CONSTITUTION:When an operation start switch SW4 is turned on upon completion of a preparation for driving a motor M, the signal of an operation start signal circuit 5 is emitted to a motor driving circuit 6 to start the revolution of a motor M, by which the winding of a tape coated thereon with a processing agent and a film is started. When the winding ends, a winding end detecting circuit 9 emits the signal for the winding end to an instructing circuit 10 for the revolving direction of the motor upon receiving the output from a revolution detecting circuit 8. The circuit 10 emits the signal for reversing the revolving direction to the circuit 6 and a timer 20. The timer 20 stops the revolution of the motor M and starts the reverse revolution thereof after a specified time to rewind the tape and the film. A signal is emitted, upon ending of the rewinding, from a rewinding end detecting circuit 21 to the circuit 10 to stop the revolution of the motor M; at the same time, a signal is emitted to an operation end buzzer circuit 22 to sound a buzzer BZ. The completion of the treatment is known from the sounding buzzer BZ. The user opens a cover 12 and takes out the film and all the operations are completed. |
