ABSTRACT:
A cleanser feeding mechanism has a cleanser housing portion, a cleanser feeding member for feeding a cleanser housed in the cleanser housing portion, and a synchronous motor for applying a drive force to the cleanser feeding member, and feeds an amount of cleanser corresponding to the number of revolutions of the synchronous motor. A cleanser feeding amount-setting unit sets an amount of cleanser to be fed from the cleanser feeding mechanism. A driving unit applies an AC source voltage of an AC power source to the synchronous motor. A counter counts the number of cycles of the AC source voltage from a timing at which the AC source voltage is applied to the synchronous motor. A reference cycle number-setting unit sets a total cycle number of the AC source voltage which corresponds to a cleanser amount set by the cleanser feeding amount-setting unit. A motor controller compares a count output from the counter with a total cycle number from the reference cycle number-setting unit and stops application of the AC source voltage to the synchronous motor when the count output and the total cycle number coincide with each other.
