Abstract

본 발명은 프린터의 전원제어장치에 관한 것으로서, 프린트 수행 중 일정시간 이상 컴퓨터로부터 데이타스트로브 신호가 인가되지 않으면 프린터 전원회로의 콘트롤 회로를 리셋시켜 프린터 전원회로의 전원을 차단하며 프린터 전원회로의 전원차단시에도 재충전 가능한 바테리를 이용하여 계속하여 데이타 스트로브 신호를 검출하여 다시 컴퓨터로부터 데이타 스트로브 신호가 인가되면 프린터 전원회로의 전원을 공급하도록 하는 전원공급제어부를 구성하여 프린터 사용도중 인자할 데이타가 계속해서 일정시간 이상 인가되지 않을 경우 전원을 차단함으로써 프린터 사용시 불필요한 전원의 낭비를 줄일 수 있도록 한 것이다.The present invention relates to a power supply control apparatus for a printer. If a data strobe signal is not applied from a computer for a predetermined time during printing, the control circuit of the printer power circuit is reset to cut off the power of the printer power circuit, and the power supply of the printer power circuit is cut. Rechargeable battery continuously detects the data strobe signal, and when the data strobe signal is applied from the computer, the power supply control unit is configured to supply power to the printer power circuit. If it is not applied for more than the time, the power is cut off so that unnecessary waste of power can be reduced when using the printer.
