PURPOSE: Provided is an automated developing processor of a printed board which allows an ultrasonic vibrator set at a nozzle part to spray developing solution from the nozzle part and to generate ultrasonic wave so that it helps to improve developing power. CONSTITUTION: In the developing processor which consists of a developing room(10), a washing room(9), a coating room for rubber solution(8) and a drying room(7), the automated developing processor of the printed board comprises the parts of: a nozzle pipe(4) which is connected by more than two supply lines to circulate the developing solution; the ultrasonic vibrator which is set at both sides of the nozzle pipe to jet the developing solution and the ultrasonic wave at the same time; and a washing pipe(2) which is set at the washing room to let washing water sprayed with uniform pressure.
