본 고안은 일정 시간후 설정된 시간동안 전원 공급하도록 한 노아게이트를 이용한 타이머회로에 관한 것이다.The present invention relates to a timer circuit using a noah gate to supply power for a set time after a certain time.

종래에도 여러가지 기계식, 전자식타이머들이 제안되었으나 이와같은 타이머들은 단지 설정된 시간동안만 지연시켜주는 기능을 행하는 것으로 로직 콘트롤 회로에 사용하기에는 적합하지 못하는 것이었다.Various mechanical and electronic timers have been proposed in the past, but these timers are only suitable for use in logic control circuits because they perform a delay function only for a set time.

로직 콘트롤 회로는 논리 소자를 사용하기 때문에 전원공급후 즉시 구동되면 노이즈로 인한 오동작을 방지할 수가 없는 것으로 전원 공급후 일정 전압이 인가될때까지 지연시켜야만 되는 것이었다.Since logic control circuits use logic elements, they cannot be prevented from malfunctioning immediately after they are powered. They had to be delayed until a certain voltage was applied.

본 고안의 목적은 전원 공급후 일정시간 지연시켜 각 회로에 정전압을 공급시키고서 설정된 시간동안 전원을 공급시키는 타이머회로를 제공하고자 하는 것으로 논리소자인 노아게이트 전후단에 각각 충방전회로를 구성시킨후 스위칭 트랜지스터로 로직 콘트롤 회로를 제어하고자 하는 것이다.The object of the present invention is to provide a timer circuit for supplying a constant voltage to each circuit by supplying a constant voltage to the circuit after a certain time delay after power supply. The switching transistor is to control the logic control circuit.
