Abstract
A printer includes a carriage, a carriage moving mechanism including a motor, a motor driver that controls the motor, a stop instruction device, and an interlock device. The stop instruction device transmits a stop signal for the carriage or stops a driving permission signal for the carriage when a predetermined stop condition is satisfied. The interlock device is interposed between the motor and the motor driver and shuts off the motor from the motor driver after a lapse of a predetermined delay time of transmitting the stop signal or stopping the driving permission signal. The motor driver controls the motor to decelerate the carriage in at least a portion of a period before the delay time has elapsed.
