Recording apparatus

摘要

A recording apparatus in which a stepping motor is used as a driving source to reciprocate a carriage on which a recording head is mounted and recording is executed by the recording head in accordance with the timing when the stepping motor rotates. The apparatus includes a rotational position detector to detect a rotational position of the stepping motor; a current switching circuit to switch energization currents to the stepping motor on the basis of a detection signal from the rotational position detector; a motor speed control circuit to closed loop control a rotational speed of the stepping motor through the current switching circuit; and a controller for detecting a load corresponding to the stepping motor by a speed control output from the motor speed control circuit and for controlling the motor so as to change output torque of the stepping motor in accordance with the load.
