일반적으로 기록매체의 주행량을 표시하기 위해 디지탈카운터를 구비한 기록재생장치는 기록 또는 재생등 기타 기록매체를 주행시킬시 주행량을 카운트 사용자에게 알려주는 기능을 갖고 있다.In general, a recording and reproducing apparatus having a digital counter to display the traveling amount of the recording medium has a function of notifying the counting user of the traveling amount when the other recording medium such as recording or playback is run.
상기 기록재생장치는 기존에 기록모드시 기록위치를 저장하기 위하여 사용자로하여금 카운트키(Count key) 및 레세트(Reset)키와 메모리키(Memory key)를 각각 순차적으로 선택하도록 제작되어 있다. 그러므로 사용자는 기록재생장치가 기록모드로 작동할시 기록할 프로그램의 기록위치를 저장하라는 명령을 지정하기 위하여 상기와 같이 카운트키 및 리세트키와 메모리키를 순차적으로 선택하여야 함으로 번거로움을 겪어야 했다.The recording and reproducing apparatus is designed to sequentially select a count key, a reset key, and a memory key, respectively, for the user to store the recording position in the recording mode. Therefore, the user had to suffer from having to sequentially select the count key, the reset key and the memory key as described above in order to designate a command to store a recording position of a program to be recorded when the recording / playback apparatus operates in the recording mode. .
따라서 본 고안의 목적은 기록재생장치에 있어서 기록모드시 자동으로 여러개의 키를 순차적으로 선택되도록 하여 사용자가 위치저장용 명령지정을 쉽게 할수 있는 기록모드시 위치저장 자동지정회로를 제공함에 있다.Accordingly, an object of the present invention is to provide an automatic position storage designation circuit in recording mode in which a user can easily designate a position storing command by automatically selecting a plurality of keys sequentially in the recording and reproducing apparatus.
상기 목적을 달성하기 위하여 본 고안은 기록재생장치에 있어서, 시스템을 제어처리하기 위한 마이크로 콤퓨터(Micro Computer;이하 마이콤이라함)과, 상기 마이콤에 접속된 키메트릭스와, 상기 키메트릭스중 소정수의 키를 순차적으로 강제선택하기 위해 상기 키들에 대한 키스캔통로들을 순차적으로 도통시키는 강제키선택수단과, 기록모드시 사용자의 선택에 의해 상기 키강제선택수단을 동작시키는 자동지정선택스위치를 포함함을 특징으로 한다.In order to achieve the above object, the present invention provides a recording / playback apparatus comprising: a microcomputer (hereinafter referred to as a microcomputer) for controlling and controlling a system, a key matrix connected to the micom, and a predetermined number of key metrics; And a forced key selection means for sequentially conducting kisscan passages for the keys to force the key to be sequentially selected, and an automatic designation selection switch for operating the key force selection means by the user's selection in the recording mode. It features.
이하 본 고안을 첨부한 도면을 참조하여 상세히 설명하기로 한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
제1도는 본 고안에 의한 실시예의 회로도로서 이를 설명하면 다음과 같다.1 is a circuit diagram of an embodiment according to the present invention.
다수의 키(K1∼K9)를 구비한 키메트릭스(20)는 마이콤(10)의 제1∼3스캔펄스출력라인(1∼3)과 마이콤(10)의 제1∼3스캔펄스입력라인(4∼6)에 접속된다. 그리고 강제키선택수단(30)은 상기 제1스캔펄스출력라인(1)을 공통으로 상기 제1∼3스캔펄스입력라인(4∼6)에 각각 접속된 제1∼3제어용스위치(CSW1-CSW3)와 상기 제1∼3제어용스위치(SW1∼SW3)를 순차적으로 제어하기 위한 스위치제어부(31)로 이루어진다. 자동지정선택스위치(SW1)는 다이오드(D1)을 통해 마이콤(10)의 기록모드제어단자에 한쪽단자를 접속하고 나머지 한쪽단지는 상기 스위치제어부(31)에 접속한다.The key metrics 20 having a plurality of keys K1 to K9 include the first to third scan pulse output lines 1 to 3 of the microcomputer 10 and the first to third scan pulse input lines of the microcomputer 10. 4 to 6). The forced key selection means 30 has first to third control switches CSW1 to CSW3 connected to the first to third scan pulse input lines 4 to 6 in common with the first scan pulse output line 1. ) And the switch control unit 31 for sequentially controlling the first to third control switches SW1 to SW3. The automatic designation selection switch SW1 connects one terminal to the recording mode control terminal of the microcomputer 10 through the diode D1, and the other terminal is connected to the switch control unit 31.
이어서 제1도에 도시된 회로의 작동을 상세히 설명한다. 설명에 앞서 키메트릭스(20)중 K1은 카운트키라 가정하고 K2∼K4는 각각 리세트키 및 메모리키와 기록키라 가정한다.Next, the operation of the circuit shown in FIG. 1 will be described in detail. Prior to the description, it is assumed that K1 in the key metrics 20 is a count key and K2 to K4 are reset keys, memory keys, and write keys, respectively.
사용자가 키메트릭스(20)중 기록키(K4)를 압압할 시 마이콤(10)은 제3스캔펄스입력라인(6)을 통해 인입되는 제2스캔펄스출력라인(2)상의 스캔펄스에 의해 기록모드가 지정되었음을 인식하여 기록모드제어단자에 접속된 라인(7)을 통해 하이논리상태의 기록모드제어신호를 저변장치로 출력함으로 기록모드로 주변장치를 제어한다.When the user presses the recording key K4 in the key metrics 20, the microcomputer 10 writes the scan pulse on the second scan pulse output line 2 which is introduced through the third scan pulse input line 6. Recognizing that the mode is specified, the peripheral mode is controlled in the recording mode by outputting the high logic state of the recording mode control signal through the line 7 connected to the recording mode control terminal.
상기 라인(7)상에 하이논리상태의 기록모드제어신호가 유기될 순간에 사용자에 의해 자동지정선택스위치(SW1)가 온(ON)되어 있을 경우 라인(7)상에 유기된 하이논리상태의 기록모드제어신호는 다이오드(D1) 및 자동지정선택스위치(SW1)을 통해 강제키선택수단(30)의 스위치제어부(31)에 공급된다. 그러면 스위치제어부(31)는 하이논리상태의 기록모드제어신호가 인가될 때 제1제어용스위치(CSW1)을 온(ON)시켰다가 오프(Off)시킨 다음 제2제어용스위치(CSW2)를 온시켰다가 오프시키고 다시 제3제어용스위치(CSW3)를 온시켰다가 오프시킨다. 상기 스위제어부(31)에 제어되는 제1∼3제어용스위치(CSW1∼CSW3)는 각각 온 될때 제1스캔펄스출력라인(1)상의 제1스캔펄스를 해당접속라인인 제1∼3스캔펄스입력라인(4∼6)을 통해 마이콤(10)에 공급한다. 그러면 마이콤(10)은 상기 강제키선택수단(30)의 제1∼3제어용스위치(CSW1-CSW3) 및 제1~3스캔펄스 입력라인(4∼6)을 통해 제1스캔펄스가 순차적으로 인입될때 카운트키(K1) 및 리세트키(K2)와 메모리키(K3)가 지정됐음을 인식하여 위치저장기능을 수행한다.When the automatic designation selection switch SW1 is turned ON by the user at the moment when the high logical state recording mode control signal is released on the line 7, the high logic state induced on the line 7 The recording mode control signal is supplied to the switch control section 31 of the forced key selection means 30 through the diode D1 and the automatic designation selection switch SW1. Then, the switch control unit 31 turns on and off the first control switch CSW1 when the recording mode control signal in the high logic state is applied, and then turns on the second control switch CSW2. OFF and turn on the third control switch CSW3 again. The first to third control switches CSW1 to CSW3 controlled by the switch control unit 31 respectively input first scan pulses on the first scan pulse output line 1 to the first to third scan pulse inputs as corresponding connection lines. It supplies to the microcomputer 10 via the lines 4-6. Then, the microcomputer 10 sequentially enters the first scan pulse through the first to third control switches CSW1 to CSW3 and the first to third scan pulse input lines 4 to 6 of the forced key selection means 30. When the count key (K1), the reset key (K2) and the memory key (K3) is assigned to perform the position storage function.
상술한 바와 같이 본 고안은 기록재생장치에 있어서 기록모드시 위치저장을 하기위한 위치저장명령지정용키들을 순차적으로 자동선택하게하여 사용자에게 주었던 여러개의 키를 조작하여야 하는 번거로움을 해소할 수 있는 이점이 있었다.As described above, the present invention enables to automatically select the position storage command designation keys for position storage in the recording mode in the recording mode, thereby eliminating the trouble of manipulating several keys given to the user. There was an advantage.
