Abstract
파워 락 스위치와; 인가되는 키신호 입력이나 파워 락 스위치의 작동 여부를 판단하여, 그에 해당하는 파워락 신호를 출력하는 전원 공급 제어부와; 상기 전원 공급 제어부에서 출력되는 파워 락 신호에 따라 작동 상태가 가변되어 인가되는 전원을 각 작동 회로로 공급하는 전원 유지부를 포함하여 이루어지는 파워 락 장치는, 전자 기기에 있어서, 사용자의 부주의나 외부의 충격으로 인하여 전원 공급 스위치가 오프되어도, 전원 공급 상태를 유지하여 데이타 손실 등을 방지할 수 있으며, 현재 작업중인 기능을 계속하여 수행할 수 있다.A power lock switch; A power supply control unit which determines whether an applied key signal input or a power lock switch is operated and outputs a corresponding power lock signal; The power lock device including a power holding unit for supplying power to each operation circuit in which an operation state is changed according to a power lock signal output from the power supply control unit is an electronic device. Therefore, even if the power supply switch is turned off, it is possible to maintain the power supply state to prevent data loss, and to continue to perform the function currently being worked on.
