PURPOSE:To dispense with a high-cost servo motor by controlling a pulse motor in feedback. CONSTITUTION:An encoder circuit 8 generates pulses in accordance with the rotation of a pulse motor 5. An encoder counter 9 counts the pulses outputted from the encoder circuit 8 and outputs this count value into a comparator 12. The comparator 12 compares the count value outputted from the encoder counter 9 with the count value outputted from a set counter 11 and when both values coincide with each other, it turns off a switching circuit 7 and cuts off the pulses outputted from a pulse generator 6 to the pulse motor 5. As a result, the rotation of the pulse motor 5 is stopped and with the count value set to the set counter 11 the rotation of the pulse motor is controlled. |
