Claims (1)

고정단자(a2-a5)에 각기 그 값이 상이한 저항(R12-R15)이 접속되고, 고정단자(a6)는 접지된 선택 스위치(SW12-R15)이 접속되고, 고정단자(a6)는 접지된 선택스위치(SW11)의 가동단자를 저항(R11) 및 중앙처리장치(11)의 아날로그신호 입력포트(AN11)에 접속하여, 중앙처리장치(11)가 인자 프로그램을 수행하면서 입력포트(AN11)에 인가된 신호를 입력하고, 그 입력한 신호의 크기에 따라 상기 스위치(SW11)의 절환상태를 판별하여 카세트 모드 및 테스트 모드, 온라인 모드, 현상 모드, 매뉴얼 모드를 선택적으로 수행하게 함을 특징으로 하는 입력포트 감소방법.The fixed terminals a 2-a 5 are connected to resistors R 12- R 15 having different values, and the fixed terminals a 6 are connected to a grounded selector switch SW 12- R 15 . The terminal a 6 connects the movable terminal of the grounded selection switch SW 11 to the resistor R 11 and the analog signal input port AN 11 of the central processing unit 11 so that the central processing unit 11 is connected. Inputting the signal applied to the input port (AN 11 ) while performing the printing program, and determines the switching state of the switch (SW 11 ) according to the magnitude of the input signal to cassette mode, test mode, online mode, development mode And selectively performing a manual mode. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
