<p>A control unit for controlling a motor (1) for use in a printer includes a position counter (6a) to count output pulses of an encoder (13) that rotates to follow rotation of the motor and detect a position of a printing medium transferred by the motor; a feed-amount modifying and calculating part (90) to calculate a modified target value of a feed-amount of the printing medium based on a target value of a feed-amount of the printing medium and a previous stop position of the printing medium detected by the position counter, and set a counted value of the position counter to the modified target value; and a position control part (6c, 6e, 6f, 6g, 6h, 6i) to control the motor so that the counted value of the position counter falls into a predetermined range including zero. The control unit provides precise feeding of paper in a printer. <IMAGE></p> |
