Abstract
A vibration damping member, for dampening vibration triggered by movement of a carriage, is driven to move by a vibration-damping drive motor that is a different drive source from a drive source of the carriage. The vibration-damping drive motor includes a stepping motor which may be controlled by an input of a pulse. A carriage-position detecting unit for detecting the position of the carriage in a moving direction updates the position count each time the carriage is moved by a predetermined amount. Each time the position count of the carriage-position detecting unit is updated by a predetermined amount, a first pulse generating unit generates a pulse that causes the vibration-damping drive motor to move by one step. The vibration-damping drive motor is driven with the pulse, thereby causing the vibration damping member to move.
