PURPOSE:To stabilize the temperature of an apparatus including a pulse motor by making the whole calorific value constant, even if the number of excitation phases energized for maintaining the stop of the pulse motor is different at the time of stopping the motor, in the pulse motor having the function capable of controlling a current flowing through the whole excitation phase of the pulse motor having a plurality of coils as excitation phases. CONSTITUTION:The title apparatus controls a device for obtaining a signal 6 for knowing how many phases are excited at the time of stopping a pulse motor and for controlling the quantity of the total current 8 of the pulse motor according to the number of the excited phases, e.g. a reference voltage generation circuit for generating a reference voltage 7 for controlling the total current value of the pulse motor. |
