본 고안은 VTR의 예약녹화 순서 제어회로에 관한 것이다.The present invention relates to a reservation recording sequence control circuit of the VTR.

종래의 VTR은 예약녹화순서가 복잡하고 어려워서 예약녹화를 하기가 힘들었을 뿐만 아니라 VTR에 별다른 지식이 없는 경우에 설명서를 보고도 VTR을 사용하기 힘들었다.In the conventional VTR, not only is it difficult to make reservation recording because the reservation recording order is complicated and difficult, but it is also difficult to use the VTR even if the user does not have much knowledge in the VTR.

또한, 예약녹화 순서중 하나만 빠뜨려도 그내용이 테이프에 기록되지 않는 문제점이 있었다.In addition, there is a problem that the contents are not recorded on the tape even if one of the reserved recording procedures is omitted.

본 고안은 상기한 문제점을 해결하기 위해 안출된 것으로서, 푸시 스위치로 펄스를 발생하고 시프트 레지스터의 출력으로 트랜지스터를 구동시켜 예약녹화순서를 표시하고 버퍼를 통해 예약녹화기능 키이를 스위칭하여 예약녹화 순서를 제어하는 예약녹화 순서제어회로를 제공함에 그 목적이 있다.The present invention was devised to solve the above problems, and generates a pulse with a push switch, drives a transistor with an output of a shift register to display a reservation recording sequence, and switches a reservation recording function key through a buffer to change the reservation recording sequence. It is an object of the present invention to provide a reservation recording sequence control circuit for controlling.

이하에 첨부된 도면에 의거하여 본 고안의 실시예를 상세히 설명한다. 제1도는 본 고안의 실시예에 따른 회로도를 나타낸 것이다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. 1 is a circuit diagram according to an embodiment of the present invention.

전원(Vcc)과 접지에 각각 접속된 푸시 스위치(SW1)와 저항(R1)의 접속됨을 4-비트 시프트레지스터(SR)의 클럭단자(CLK1)에 연결하고, 시프트레지스터(SR)의 출력(O1-O4)을 전원단자(Vcc)에 콜렉터가 접속된 트랜지스터(Q1-Q4)의 베이스에 각각 연결하며, 에미터를 밭광다이오드(LED1-LED4)를 통해 저항(R2-R5)에 연결하고, 트랜지스터(Q1-Q4)의 에미터 출력에 의해 제어되는 버퍼 스위치(SW2-SW7)의 일단을 기능키(FK)에 연결하며, 타단을 시스템 콘트롤러(SC)에 연결구성하였다.Connect the push switch SW 1 and the resistor R 1 connected to the power supply Vcc and ground to the clock terminal CLK 1 of the 4-bit shift register SR, respectively. output (O 1 -O 4) via the power supply terminal (Vcc) of the transistors (Q 1 -Q 4) connected respectively and batgwang an emitter diode (LED 1 -LED 4) to the base of the collector is connected to the resistance ( R 2 -R 5 ), one end of the buffer switch (SW 2 -SW 7 ) controlled by the emitter outputs of transistors (Q 1 -Q 4 ) to the function key (FK), the other end of the system Connected to the controller (SC).

상기 구성된 본 고안의 동작을 설명하면 다음과 같다.Referring to the operation of the present invention configured as described above are as follows.

예약녹화를 하기 위해 푸시 스위치(SW1)를 누르면 시프트레지스터(SR)의 클럭단자(CLK1)에 펄스가 입력되어 출력단자(O1)를 통해 "H"레벨의 비트가 출력된다. 이 출력이 트랜지스터(Q1)의 베이스에 인가되어 트랜지스터(Q1)가 온이 되므로 프로그램 체크표시인 발광다이오드(LED1)가 온이 되고, 또한 버퍼스위치(SW2)가 온이 되므로 기능키이(FK)중 프로그램 체크 키이(P-PHECK)로 프로그램 체크를 세팅시킬 수 있다.When the push switch SW 1 is pressed to perform the reserved recording, a pulse is input to the clock terminal CLK 1 of the shift register SR, and a bit having an “H” level is output through the output terminal O 1 . This output is applied to the base of the transistor (Q 1) and the transistor (Q 1) the so the whole program check a light emitting diode (LED 1) on, and also since the buffer switch (SW 2) on function key You can set the program check with the Program Check Key (P-PHECK) in (FK).

프로그램 체크 세팅후 푸시 스위치(SW1)를 한번 더 누르면 펄스가 발생되어 클럭단자(CLK1)에 인가되므로 시프트레지스터(SR)는 출력단자(O1)를 통해 "H"레벨을 출력한다. 따라서 트랜지스터(Q2)가 온이 되므로 발광다이오드(LED2)가 온이되어 날짜(DAY)를 표시하고, 버퍼 스위치(SW2)가 온이 되므로 기능키이(FK)중 날짜키이(DAY)로 날짜를 맞출수 있다.When the push switch SW 1 is pressed once more after the program check setting, a pulse is generated and applied to the clock terminal CLK 1 , so the shift register SR outputs an “H” level through the output terminal O 1 . Therefore, since the transistor Q 2 is turned on, the light emitting diode LED 2 is turned on to display the date DAY, and the buffer switch SW 2 is turned on, so that the date key DAY is selected from the function keys FK. You can set the date.

날짜를 맞춘후 푸시 스위치(SW1)를 누르면 상기한 바와같이 시프트레지스터(SR)는 출력단자(O3)를 통해 "H"레벨을 출력하여 트랜지스터(Q1)가 온이되므로 발광다이오드(LED3) 가 온이 되어 시간(TIME)을 표시하고, 버퍼 스위치(SW4, SW5)가 온시키므로 시간키이(TIME+, TIME-)로 시간을 맞출수 있다.After setting the date and pressing the push switch (SW 1 ), as described above, the shift register (SR) outputs the "H" level through the output terminal (O 3 ) so that the transistor (Q 1 ) is turned on. 3 ) The time is turned ON to display the time and the buffer switches SW 4 and SW 5 are turned on to set the time with the time keys TIME + and TIME-.

시간을 맞춘 후 푸시 스위치(SW1)를 누르면 시프트레지스터(SR)는 출력단자(O3)를 통해 "H"레벨을 출력하여 트랜지스터(Q1)를 온이되므로 발광다이오드(LED4)가 온이되어 채널(CHANNEL)을 표시하고, 버퍼 스위치(SW6, SW7)가 온이되므로 채널을 맞출 수 있다.After pressing the push switch SW 1 , the shift register SR outputs the “H” level through the output terminal O 3 to turn on the transistor Q 1 so that the light emitting diode LED 4 is turned on. Then, the channel CHANNEL is displayed, and the buffer switches SW 6 and SW 7 are turned on so that the channel can be tuned.

상기한 푸시 스위치(SW1) 동작에 의해 예약녹화동작을 순서대로 수행할 수 있어 용이하게 예약녹화를 할 수 있다.By the push switch SW 1 operation, the reservation recording operation can be performed in order, so that the reservation recording can be easily performed.

이때 푸시 스위치(SW1)를 한 번 더 누르면 맨 처음의 상태로 되돌아 간다.Press the push switch (SW 1 ) once more to return to the initial state.

VTR의 예약녹화시 순서가 복잡하고 까다로을 뿐만 아니라 예약녹화순서를 빠뜨릴 경우에 녹화가 안되는 종래의 문제점을 개선한 본 고안의 회로에 따르면, 푸시스위치로 펄스를 발생하고 시프트레지스터의 출력에 따라 트랜지스터를 구동시키므로서 트랜지스터의 스위칭 동작에 의해 예약녹화순서 표시용 발광다이오드를 시켜 예약녹화 순서를 표시할 뿐만 아니라 버퍼 스위치에 의해 기능키이를 제어하여 편리하게 예약녹화를 수 있으며, 따라서 제품에 대한 신뢰성을 높일 수 있다.According to the circuit of the present invention, which improves the conventional problem that the recording of VTR is complicated and difficult as well as the conventional recording, when the recording order is omitted, the pulse is generated by the push switch and the transistor is outputted according to the output of the shift register. By operating the transistor, the light emitting diode for displaying the reservation recording order is displayed by the switching operation of the transistor to display the reservation recording order, and the function keys are controlled by the buffer switch to conveniently reserve the recording. It can increase.
