Claims (2)

마이크로콤퓨터를 이용한 비디오시스템 잠김장치에 있어서, 사용자의 키조작에 의하여 숫자와 확인, 해제, 변경, 잠김의 신호를 발생시켜 출력하는 키보드(1)와, 상기 키보드(1)에서 입력되는 n자리의 10진수를·차례로 변환하여 n비트 2진수 n바이트를 출력하는 인코우더(2)와, 상기 키보드(1)에서 입력되는 확인. 잠김, 해제, 변경신호와 다른 제어신호를 입력하고 이를 처리하여 제어신호를 출력하는 마이크로콤퓨터회로(3)와. 상기 키보드(1)에서 숫자키가 펀칭될 때 마다 입력되는 클릭펄스와 마이크로콤퓨터회로(3)에서 입력되는 클럭펄스 신호를 카운팅하므로 n개의 어드레스를 발생하여 출력하는 n비트의 2진 카운터(4)와, 상기 마이크로콤퓨터 회로(3)에서 인가되는 리드와 라이트신호와 리셀트 신호에 따라 인코우더(2)에서 입력되는 n바이트의 n비트 2진 정보와 2진 카운터(4)에서 입력되는 n기의 어드레스를 저장하거나 어드레스에 해당하는 저장된 정보신호를 출력하며 저장된 정보를 삭제하는 램 회로(5)와. 상기 인코우더(2)에서 입력되는 n바이트의 n비트 2진 정보와 램 회로(5)에서 입력되는 n바이트의 n비트 2진 정보를 비교하여 출력하는 비교회로(6)으로 구성됨을 특징으로 하는 장치.In a video system locking apparatus using a microcomputer, a keyboard (1) for generating and outputting a number, a confirmation, a release, a change, and a lock signal by a user's key operation, and an n-digit input by the keyboard (1). The encoder (2) which converts a decimal number in turn, and outputs n-bit binary n bytes, and the confirmation input from the said keyboard (1). And a microcomputer circuit (3) for inputting lock, release, change signals and other control signals and processing them to output control signals. Each time the numeric key is punched in the keyboard 1, the click pulse inputted and the clock pulse signal inputted in the microcomputer circuit 3 are counted, so that the n-bit binary counter 4 generates and outputs n addresses. And n bytes of n-bit binary information input from the encoder 2 and n input from the binary counter 4 according to the read and write signals and the receptacle signal applied from the microcomputer circuit 3. A RAM circuit 5 for storing an existing address or outputting a stored information signal corresponding to the address and deleting the stored information; And a comparison circuit (6) for comparing and outputting n-byte binary information of n-bytes inputted from the encoder (2) and n-bit binary information of n-bytes inputted from the RAM circuit (5). Device. 마이크로콤퓨터를 이용한 비디오 잠김 장치에서 VTR을 잠그는 방법에 있어서. VTR의 잠김 상태를 확인하는 제 1단계와, 상기 제 1단계에서 잠겨있지 않은 경우 사용자가 잠글 것인가를 결정하는 제 2단계와, 상기 제 2단계에서 잠글 경우 비밀번호를 저장시키는 제 3단계와. 상기 제 1단계에서 잠겨있을 시발광다이오드(31)을 점등시키는 제 4단계와 제 4단계 수행후 키보드(1)의 숫자키를 눌러 비밀번호를 입력하고 저장된 정보와 같은가를 비교하여 다를시 제 4단계로 되돌아가는 제 5단계와, 상기 제 5단계에서 같을 시 사용자가 해제할 것인가 변경할 것인가를 결정하여 변경할 시 3단계로 되돌아가는 제 6단계와, 제 3계에서 잠그지 않을 시 비디오테이프 구동부를 온(ON)시키는 제 7단계와, 제 6단계에서 해제할 치 비디오테이프 구동부를 온(ON)시키는 제 8단계를 이루어짐을 특징으로 하는 VTR시 스템 잠금 방법.A method of locking a VTR in a video locking device using a microcomputer. A first step of checking a locked state of the VTR, a second step of determining whether the user locks if it is not locked in the first step, and a third step of storing a password if the second step is locked in the second step; After performing the fourth and fourth steps of turning on the time light emitting diode 31 to be locked in the first step, enter a password by pressing the numeric keys of the keyboard 1 and compare the stored information with the stored information. The fifth step of returning to the same step, the sixth step of returning to step 3 when the user decides to release or change the same time in the fifth step, and the videotape driving unit when the third system is not locked, And an eighth step of turning on the chi videotape driver to be released in the sixth step. ※ 참고사항 : 최초출원내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
