PURPOSE:To prevent a driving wire from being broken and to operate a motor at the start by holding a cleaner at a home position so that the motor is unlocked, a cleaning member does not contact a charge wire, and no tension is applied to the driving wire. CONSTITUTION:A detection member 17 detects the state before locking and a controller is so provided that the coupling projection 14a of a worm wheel 14 which presses the coupling projection 4a of a pulley 4 is reversed by reversing the motor 12 and the coupling projection 4a of the pulley 4 is stopped at a noncontact position. At this time, cleaning members 8-11 are positioned in parallel to the charge wire 3 without contacting. Therefore, while the cleaners are positioned at their home positions, no tension operates on the driving wire. Consequently, the driving wire is hardly broken and used for a long period, and the worm gear and a worm gear wheel are not locked at the start, so the motor is driven smoothly.
