ABSTRACT:
Upon operation of an erasure key for erasing a printed character, a correction ribbon is moved in an erasure position according to rotation of a motor, and then, the motor is continuously rotated forward at a current I2 larger than a current I1 in a print operation. Therefore, a print hammer is accelerated to a speed V2 higher than a speed V1 in the print operation, to strike a platen at the speed V2. In the erasing operation, no pressing operation is performed after the stroke. Rather, the print hammer is immediately returned and the ink is removed.
