Abstract: PURPOSE:To reduce a torque necessary for a pulse motor and to attain reduction in cost of the motor by performing the current switching point of the pulse motor when load is stabilized at a constant speed. CONSTITUTION:In an optical system, the large torque is necessary at the time of starting driving, so that a current value to the motor 26 is made large and the motor is slowed up to a target speed by sequentially changing the speeds.

Now, the current switching point detection sensor 80 detects markers put on the optical system so as to detect that the optical system is in a stable state. Thus, the load can be driven with an inexpensive pulse motor without making the torque necessary for the pulse motor 26 so large.
