본 고안은 타이머를 이용하여 사용자가 세팅시킨 시간에 자동으로 기록할 수 있게 함은 물론 비디오 테이프에 기록된 영상신호를 재생할 수 있게한 비디오 테이프 레코오더의 예약회로에 관한 것이다.The present invention relates to a reservation circuit of a videotape recorder that enables recording of video signals recorded on a videotape as well as automatic recording at a time set by a user using a timer.

종래의 비디오 테이프 레코오더는 타이머를 이용하여 사용자가 세팅시킨 시간에 기록만 할 수 있게 하였으므로 사용자가 원하는 시간에 비디오 테이프를 재생시켜 영화감상 또는 시청각 교제등을 시청할 수 없는 결함이 있었다.In the conventional video tape recorder, only a user can record at a time set by a user using a timer, so that the user can play a video tape at a desired time to watch a movie or an audiovisual companionship.

본 고안은 이와 같은 종래의 결함을 감안하여, 하나의 타이머를 이용하여 세팅시킨 시간에 원하는 프로그램을 녹화할 수 있게 함은 물론 세팅시킨 시간에 영화감상 또는 시청각 교재등을 시청할 수 있게 안출한 것으로 이를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.The present invention allows for recording a desired program at a set time using a single timer in consideration of such a conventional deficiency, as well as for watching a movie or an audio-visual textbook at a set time. When described in detail with the accompanying drawings as follows.

제1도에 도시한 바와 같이 전원단자(Vcc)를 저항(R1) 및 예약기록/재생스위치(SW1)를 통해 저항(R2) 및 트랜지스터(TR1)의 베이스에 접속하여 트랜지스터(TR1)의 콜렉터를 제어단자(S)에 타이머(1)가 접속된 제어부(2)의 입력측 및 저항(R3)에 공통접속하고, 제어부(2)의 출력측은 인버터(I1) 및 다이오드(D1)를 통한 후 재생스위치(SW2)를 통한 전원단자(Vcc)와 함께 플레이(play) 신호출력단자(P)에 접속하며, 또한 그 제어부(2)의 출력측을 기록스위치(SW3)와 함께 기록신호출력단자(REC)에 접속함과 동시에 그 접속점을 다이오드(D2)를 통해 플레이 신호출력단자(P)에 접속하여 구성한 것으로 상기에서 제어부(2)는 타이머(1)가 세팅된 일정시간동안 그의 입력측에 인가된 전위를 출력하고, 플레이 및 기록신호출력단자(P)(REC)는 고전위가 출력될때 플레이 및 기록하게 된다.As shown in FIG. 1, the power supply terminal Vcc is connected to the base of the resistor R 2 and the transistor TR 1 through the resistor R 1 and the reservation recording / reproducing switch SW 1 to connect the transistor TR. 1) connected in common, and the output side of the control unit 2, an inverter (I 1) and a diode to the input side and a resistor (R 3) of the control terminal (S), a collector-timer (1) the control unit (2) connected to the ( D 1 ) and then to the play signal output terminal P together with the power supply terminal Vcc through the regeneration switch SW 2 , and the output side of the control unit 2 to the recording switch SW 3 . And the connection point is connected to the play signal output terminal P through the diode D 2 , and the control unit 2 has the timer 1 set therein. The potential applied to its input side is output for a predetermined time, and the play and record signal output terminals P (REC) are used when the high potential is output. Will be locked.

이와같이 구성된 본 고안의 작용효과를 상세히 설명하면 다음과 같다.Referring to the effects of the present invention configured in this way in detail as follows.

전원단자(Vcc)에 전원이 인가되고, 예약기록을 하기 위하여 예약기록/재생스위치(SW1)를 개방시키며, 타이머(1)를 원하는 시간에 세팅시키면, 트랜지스터(TR1)의 베이스 전위는 저전위가 되어 오프되므로 제어부(2)의 입력측에는 고전위가 인가된다.When the power is supplied to the power supply terminal Vcc, the reservation recording / reproducing switch SW 1 is opened for reservation recording, and the timer 1 is set at a desired time, the base potential of the transistor TR 1 is low. Since the potential is turned off, a high potential is applied to the input side of the control unit 2.

이와 같은 상태에서, 사용자가 세팅시킨 시간이 되면 제어부(2)의 제어단자(S)에 고전위가 인가되어 그의 출력측에는 입력측에 인가된 고전위가 출력되고, 그 고전위는 기록신호출력단자(REC)로 출력됨과 동시에 다이오드(D2)를 통해 플레이 신호출력단자(P)로 출력되므로 비디오 테이프 레코오더는 기록상태로 되어 입력되는 신호를 비디오 테이프에 기록하게 된다.In this state, when the time set by the user is reached, a high potential is applied to the control terminal S of the control unit 2, and a high potential applied to the input side is output on the output side thereof, and the high potential is recorded on the recording signal output terminal ( At the same time as the output to REC, the output signal is output to the play signal output terminal P through the diode D 2. Thus , the video tape recorder is in a recording state and records the input signal on the video tape.

그리고, 예약재생을 하기 위하여 비디오 테이프 레코오더에 재생할 비디오 테이프를 내장하고, 예약기록/재생스위치(SW1)를 단락시키며, 타이머(1)를 원하는 시간에 세팅시켜 놓으며, 전원단자(Vcc)의 전원이 저항(R1) 및 예약기록/재생스위치(SW1)를 통해 트랜지스터(TR1)의 베이스에 인가되어 그를 온시키게 되므로 전원단자(Vcc)의 전원이 저항(R3) 및 트랜지스터(TR1)를 통해 접지로 흘러 제어부(2)의 입력측에 저전위가 인가된다.Then, the video tape recorder has a built-in video tape to be played back, the reservation record / play switch SW 1 is short-circuited, the timer 1 is set at a desired time, and the power supply terminal Vcc Since the power is applied to the base of the transistor TR 1 through the resistor R 1 and the reservation recording / reproducing switch SW 1 to turn it on, the power supply of the power supply terminal Vcc is connected to the resistor R 3 and the transistor TR. The low potential is applied to the input side of the control unit 2 by flowing to ground through 1 ).

이와 같은 상태에서 일정시간이 경과하여 세팅시킨 시간이 되면, 제어부(2)의 제어단자(S)에 고전위가 인가되어 그의 출력측에는 입력측에 인가된 저전위가 출력되고, 그 저전위는 인버터(I1)를 통해 고전위로 반전된 후 다이오드(D1)를 통해 플레이신호출력단자(P)로 출력되므로 비디오 테이프 레코오더는 재생 상태로 되어 내장된 비디오 테이프를 재생하게 된다.When a predetermined time has elapsed in such a state, a high potential is applied to the control terminal S of the control unit 2, and a low potential applied to the input side is output to the output side thereof, and the low potential is converted into an inverter ( After inverting to high potential through I 1 ) and outputting to the play signal output terminal P through the diode D 1 , the video tape recorder is in a playback state to play the embedded video tape.

그리고, 사용자가 재생스위치(SW2)를 단락시키면, 전원단자(Vcc)의 전원이 재생스위치(SW2)를 통해 플레이신호출력단자(P)로 출력되므로 비디오 테이프 레코오더는 그 즉시 재생상태로 되고, 기록스위치(SW3)를 단락시키면, 전원단자(Vcc)의 전원이 기록스위치(SW3)를 통해 기록신호출력단자(REC)로 출력됨과 동시에 다이오드(D2)를 통해 플레이신호출력단자(P)로 출력되어 비디오 테이프 레코오더는 기록 상태로 된다.When the user short-circuits the play switch SW 2 , the power supply of the power supply terminal Vcc is output to the play signal output terminal P through the play switch SW 2 , so that the video tape recorder immediately returns to the play state. When the recording switch SW 3 is shorted, the power of the power supply terminal Vcc is outputted to the recording signal output terminal REC through the recording switch SW 3 and at the same time the play signal output terminal through the diode D 2 . The video tape recorder is output to (P), and the video tape recorder is in a recording state.

한편, 제2도는 본 고안을 실시함에 있어서, 예약 재생할 경우에 세팅시킨 시간이 되면 부저를 울려 이를 알려주게 한 다른 실시예를 보인 것으로 이에 도시한 바와 같이 인버터(I1) 및 다이오드(D1)의 접속점에 콘덴서(C1) 및 저항(R4), 부저(3)를 병렬로 접속하여 구성한 것이다.Meanwhile, FIG. 2 shows another embodiment in which the buzzer sounds when the time is set in the case of reserved reproduction in the implementation of the present invention, as shown in the inverter I 1 and the diode D 1 . The capacitor C 1 , the resistor R 4 , and the buzzer 3 are connected in parallel to the connection point of.

이와 같이 구성된 본 고안의 다른 실시예는 예약 재생시 세팅시간이 되면 제어부(2)의 출력측에는 일정시간동안 저전위가 출력되고 그 저전위는 인버터(I1)를 통해 고전위로 반전되므로 상기와 같이 플레이신호출력단자(P)로 고전위가 출력됨과 동시에 콘덴서(C1)에 충전되고, 콘덴서(C1)에 일정전압이 충전되면 부저(3)가 울려 예약재생시간이 되었음을 알리게 되며, 일정시간이 경과하여 제어부(2)의 출력측에 저전위가 출력되지 않으면, 콘덴서(C1)에 충전된 전압이 저항(R4)을 통해 방전되면서 부저(3)의 구동이 차단된다.In another embodiment of the present invention configured as described above, when the set time at the time of the reserved reproduction, the low potential is output to the output side of the controller 2 for a predetermined time, and the low potential is inverted to high potential through the inverter I 1 as described above. soon as the high-potential output to the play signal output terminal (P) are simultaneously charged to the capacitor (C 1), when a predetermined voltage is charged in the capacitor (C 1) is informed that the scheduled playback time the buzzer 3 ring, a period of time When the low potential is not output to the output side of the controller 2 after this time, the voltage charged in the capacitor C 1 is discharged through the resistor R 4 , and the driving of the buzzer 3 is interrupted.

여기서, 저항(R4)의 값을 조정하면, 플레이신호출력단자(P)로 고전위가 출력되고, 그 고전위에 의해 비디오 테이프 레코오더의 기계장치가 구동되어 재생을 시작하기 전까지 부저(3)가 구동되게 할 수 있다.Here, when the value of the resistor R 4 is adjusted, the high potential is output to the play signal output terminal P, and the high potential is driven by the mechanism of the video tape recorder to start the play of the buzzer 3 until the playback starts. Can be driven.

이상에서 설명한 바와 같이 본 고안은 비디오 테이프 레코오더의 예약기록은 물론 예약재생도 할 수 있으므로 비디오 레코오더를 보다 편리하게 사용할 수 있는 효과가 있다.As described above, the present invention can make reservation recording as well as reservation recording of the videotape recorder, so that the video recorder can be used more conveniently.
