description PURPOSE: A device for detecting remaining amount of paper in a printer is provided to detect remaining amount of paper as well as existence of paper. CONSTITUTION: In the case that lots of paper is loaded in a loading plate(122), a gap between a magnet installed on a pickup roller(130) and a magnetic sensor(140) become wide, so the strength of magnetism decreases. In the case that little paper is loaded in the loading plate, the magnet becomes close to the magnetic sensor, so the strength of magnetism increases. An amount calculator(160) calculates the remaining amount of paper from the strength of the magnetism. 개시된 인쇄기기의 기록지 잔량 검출장치는, 기록지에 접촉되어 회전하는 픽업롤러를 이용하여 기록지가 적재된 적재부로부터 기록지를 인출하여 인쇄하는 인쇄기기의 기록지잔량검출장치로서, 픽업롤러에 설치되는 마그넷과, 적재된 기록지를 사이에 두고 마그넷과 대향되는 위치에 마련되어 마그넷으로부터 방출되어 적재된 기록지를 투과한 자기량을 검출하는 자기검출부와, 이 자기의 세기로부터 기록지의 잔량을 산출하는 잔량산출부를 포함한다. 이와 같은 구성에 의해, 기록지를 투과한 자기량을 검출함으로써 기록지의 유무뿐 아니라 잔량까지도 검출할 수 있다.
