RECIPROCAL MECHANISM, CONTROL METHOD THEREFOR, TICKET CUTTING DEVICE EQUIPPED WITH RECIPROCAL MECHANISM, AND SHEET PROCESSING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a reciprocal mechanism, a control method therefor, a ticket cutting device equipped with the reciprocal mechanism, and a sheet processing device, for stopping a movable member driven with a DC motor at a target position while suppressing wearing of a brush of the DC motor when stopping the movable member driven with the DC motor at a target position.;SOLUTION: The control method is for a reciprocal mechanism, wherein a movable member is reciprocated within a predetermined range by a DC motor equipped with a commutator and a brush, and the movable member is stopped at a predetermined standby position within a predetermined range. It includes a motor deceleration step S20 of stopping an operated DC motor by detecting that the movable member reaches a preset reference position and gradually decreasing an input to the DC motor for deceleration based on the detection result, and a motor stop step S30 of detecting that the movable member reaches a standby position after reaching the reference position and stopping an input to the DC motor for stopping the DC motor based on the detection result.;COPYRIGHT: (C)2010,JPO&INPIT
