Abstract
A method for controlling stopping of a vibration generating stepping motor is a method for controlling the stopping of an vibration generating stepping motor by a control unit, characterized in that the method includes: stopping a supply of a driving pulse to the vibration generating stepping motor while applying a driving voltage to the vibration generating stepping motor; applying the driving voltage to the stepping motor, which does not completely stop, for an optimum braking time according to a motor configuration of the stepping motor, so as to brake the stepping motor; and stopping the applying of the driving voltage to the stepping motor which is rotating under inertia after the elapse of the optimum braking time.
