Abstract
PURPOSE:To enable the accurate decision of a position even if hunting happens to a motor, by a method wherein, in a pulse motor-driven printer, the number of pulses generated during a period ranging from a detection of a carrier to stoppage is counted, and a printing start position is decided based on the counting value. CONSTITUTION:With a reverse direction start signal BW brought to (1), a pulse motor 6 is caused to run reversely to move a carrier 1 leftward. If a shielding plate 3 is inserted into a recess in a leftmost sensor 11 and a change deciding phase output signal PHA, indicating a change in the phase of the pulse motor, is outputted, an inrush detecting circuit outputs an output signal to a counter 14 to count step pulses generated until the pulse motor stops running. Then, if a positive direction start signal FW (1) is aoplied to the pulse motor 6, an up- down counter 14 counts down a counting value to output an output signal to a detecting counter 15 at a time when brought to a zero. When a carrier 1 is moved in a positive direction until the detecting counter 15 counts a given value and attains a given value, the counter 15 outputs a printing start signal.
