一种记录装置，其减小了电动机的速度变化和振动，使用步进电动机作为承载器的驱动源，该承载器用于承载安装有记录器或记录介质的滑架。所述装置包括控制器，所述控制器在加速所述步进电机时控制所述步进电机，使得当所述电机的旋转速度小于指定值时以比所述载体的机械时间常数短的周期驱动所述步进电机，并且使得当所述电机的旋转速度大于所述指定值时以比所述机械时间常数长的周期驱动所述电机。
A recording apparatus which has reduced the speed variation and vibration of the motor uses a step motor as a driving source for a carrier for carrying a carriage mounted with a recorder or a recording medium. The apparatus includes a controller that, on accelerating the step motor, controls the step motor so that the step motor is driven with a shorter period than the mechanical time constant of the carrier when the rotary speed of the motor is less than a specified value, and so that the motor is driven with a longer period than the mechanical time constant when the rotary speed of the motor is more than the specified value.
