Abstract
A printer is provided comprising a carriage on which recording head is mounted. Drive mechanisms for moving carriage in reciprocating motions an encoder having openings provided contiguously in the circumferential direction at fixed intervals, attached thereto, and which rotates as carriage moves. A position detector is provided in proximity to the encoder for detecting the encoder's detection-target unit and generates timing pulses in response thereto. A shielding plate is attached to carriage for blocking the encoder from the position detector at the home position. A processor detects the home position for carriage based upon a timing pulse pause time.
