Abstract

PURPOSE:To exactly position the homing of a carriage and a type wheel with a high accuracy by a method in which the type wheel is coupled with a wheel stopper at the place where the carriage is forcibly stopped by a stopper. CONSTITUTION:Restore command RS is put in a control circuit 8, a carriage 1 is moved to the left by a direction indicating signal SP-DIR, a motor drive signal SP-DRV, and a speed indicating signal SP-Vl and contacted with a carriage stopper 5, and the carriage 1 and the motor M1 are forcibly stopped. Then, signals SL-DIR, SL-DRV, and SL-Vl are output from the circuit 8, a motor M2 is turned in a given direction by a section positioning finger 7, the type wheel is forcibly stopped by coupling it with the wheel stopper 6 fixed to the frame 3 side, and the carriage 1 and the type wheel are positioned.
