PURPOSE:To suppress the occurrence of noise by vibration to be transmitted from a carrier to the side frame by elastically supporting the carrier pulley to change the direction of a wire wound around the carrier pulley and serving to move the carrier. CONSTITUTION:A wire 8 to linearly move a carrier 2 is wound around a motor pulley 7, and its direction is changed by a guide pulley 10. The wire 8 is further wound around the carrier pulley 11 and its direction is changed. Both ends of the wire 8 are supported on the frame 9. Since the pulley 11 is elastically supported on the carrier 2 through a buffer, the vibration of the carrier 2, propagating in the wire 8, is absorbed, and noise caused by vibration in the frame 9, etc., can thus be suppressed. |
