PURPOSE:To shorten a detecting time even if a failure such as motor lock is generated and to reduce damage to be applied to parts by checking respective steps of control for a cleaning member driving motor. CONSTITUTION:A cleaning member movable member guide 3 arranged along the longitudinal shaft on the inner bottom of a casing 1 is loosely engaged with a plastic-made movable part 8 fitting a member 6 for holding a cleaning member (cleaning pad) 7 and a center shaft 16 for the rotation of the moving part 8 Both ends of a driving wire 5 for moving the movable part 8 along the guide 3 are deflectively coupled with both the sides of the moving part 8 and endlessly formed. One end of the wire 5 is laid to a driving pulley 12 with a worm wheel pivoted around an end block 9 and the other end is connected to a subdriving pulley pivoted in an end block 2 and the both end are held with tensile force. A home position detecting sensor 13 for the movable part 8 interlocks with a detecting filler for the movable part 8 to open the electric circuit of a driving motor 10. |
