Abstract

According to the invention, when directed to slow down a driven device, the speed of a driving motor is reduced from a first speed to a slower second speed. In this state, a driving gear continues to rotate at said second speed, whereas a driven gear continues to rotate by inertia and gradually slows down from said first speed. Thus, the rear of a cog of the driven gear is separated from the front of a cog of the driving gear. When the speed of the driven gear is equal to the second speed, i.e., the speed of the driving gear, the front of another cog of the driven gear reaches the rear of said cog of the driving gear. Accordingly, both gears lightly make contact. Thereafter, the driving motor is rapidly braked by maintaining the contact of the driving gear and driven gear such that both gears slow down and stop. When slowing down a driven device, noise generated by the impact of both gears is reduced as much as possible, and the time for slowing down a driven device is reduced.
