Claims (1)

수치로서 표시부에 시간을 포시하는 디지틀 시계를 구비한 전자 제품에 있어서 : 평시에는 상기의 표시부를 구동시키는 제1신호를 발생시키고, 24시간 마다 한번씩 소정의 시간에 디지틀 시계의 시각을 정확히 셋팅하기 위한 제2신호를 발생시키기 위한 제어부와 : 상기 제어부에서 발생된 제2신호를 입력으로 소정의 시간동안만 동작하여 각부에 전원을 인가시키기 위한 타이머와 : 상기 타이머의 동작에 의해 전원이 인가될 경우 라디오 수신기로부터 수딘되는 라디오 방송을 적정한 레벨로 증폭하기 위한 완충 증폭부 및 : 상기 타이머의 동작에 의해 전원이 인가될 경우 동작하여 라디오 방송중 매시 정각에 발생되는 시보음과 동일한 주파수의 시보음을 연속적으로 발생시키기 위한 시보음 발생부와 : 상기의 완충증폭부에서 출력되는 라디오 방송신호와 시보음 발생부의 출력신호를 비교하며, 비교한 두 신호의 주파수가 같을 경우 하이신호를 출력시키기 위한 비교부와 : 상기의 비료부에서 출력되는 하이신호를 입력으로 동작하여 상기의제어부에 리세트신호를 제공하여 상기의 표시부에 표시되는 시각을 정각으로 리세트 시키기 위한 리세트부로 구성시켜서 됨을 특징으로하는 시각 자동 조정회로.In an electronic product having a digital clock for displaying a time on a display part as a numerical value, the electronic device comprising: generating a first signal for driving the display part in a normal time and setting the time of the digital clock accurately at a predetermined time every 24 hours. A controller for generating a second signal; a timer for supplying power to each unit by operating the second signal generated by the controller only for a predetermined time; and when power is supplied by an operation of the timer A buffer amplifier for amplifying the radio broadcast received from the receiver to an appropriate level; and operating when the power is applied by the operation of the timer to continuously generate a signal having the same frequency as that produced at the hourly time during the radio broadcast. Time signal generator for making and: radio broadcast signal output from the buffer amplifier And a comparator for outputting a high signal when the frequencies of the two compared signals are the same, and a comparator for outputting a high signal: the high signal output from the fertilizer is operated as an input and reset to the controller. And a reset section for providing a signal to reset the time displayed on the display section at a right angle. ※ 참고사항 : 최초출원 내용에 의하여 공개되는 것임.※ Note: This is to be disclosed by the original application.
