본 고안은 더블데크 VTR에 관한 것으로 특히 테이프릴레이기능을 구비한 더블데크 VTR에 관한 것이다.The present invention relates to a double deck VTR, and more particularly to a double deck VTR having a tape relay function.
최근 VTR의 다기능화 다품종화 추세에 따라 더블데크 VTR이 보급되고 있다. 더블데크 VTR은 하나의 VTR에 한쌍의 데크를 구비하여 비디오 테이프의 복사를 하나의 VTR로 수행할 수 있도록 한 것이다.In recent years, the double deck VTR is spreading according to the trend of multifunctional and multi-functional VTR. The double-deck VTR is provided with a pair of decks in one VTR so that copying of the video tape can be performed in one VTR.
통상의 VTR은 하나의 데크를 구비하고 있는 바, 예약녹화를 할 때 테이프의 잔량이 부족한 상태에서 녹화에 들어갔을 경우 소비자가 녹화하고자하는 프로그램의 일부만 녹화되게 되므로 소정 프로그램의 전부를 예약녹화하는데 실패하게 된다. 따라서, 소비자는 예약녹화시 반드시 테이프의 잔량을 확인하여 예약녹화하고자 하는 프로그램의잔양에 맞는 테이프를 준비하여야 하기 때문에 불편하였고 테이프의 효율적인 이용을 할 수 없었다.Normal VTR is equipped with one deck, so if the recording is made when the remaining tape is insufficient during the scheduled recording, only a part of the program that the consumer wants to record will be failed. Done. Therefore, the consumer has to check the remaining amount of tape at the time of reservation recording and prepare a tape suitable for the remaining amount of the program to reserve recording, which is inconvenient and could not use the tape efficiently.
마찬가지로, 데블데크 VTR에 있어서도 각각의 데크에 장착된 테이프에 예약녹화를 하고자 할 경우에는 전술한 문제점을 가지고 있었다.Similarly, in the Devil deck VTR, the above-described problems were required when the recording of the tape mounted on each deck was to be performed.
따라서, 더블데크 VTR은 두개의 데크를 구비하여 단일데크 VTR에 비해 복사기능을 수행할 수 있으나 상술한 바와 같은 예약녹화시 테이프 잔량의 효율적인 이용면에 있어서는 단일데크 VTR과 마찬가지로 문제점을 가지고 있으므로 더블데크라는 장점을 충분히 활용할 수 없었다.Therefore, the double deck VTR is equipped with two decks and can perform a copy function as compared to the single deck VTR. However, the double deck VTR has the same problem as the single deck VTR in terms of the efficient use of the remaining tape amount in the reservation recording as described above. Could not take full advantage of the advantage.
본 고안의 목적은 테이프 릴레이기능을 구비한 더블데크 VTR을 제공하는 것이다.An object of the present invention is to provide a double deck VTR with a tape relay function.
본 고안의 다른 목적은 테이프 잔량을 효율적으로 이용할 수 있는 더블데크 VT R을 제공하는 것이다.Another object of the present invention is to provide a double-deck VT R that can effectively utilize the remaining tape.
본 고안의 또다른 목적은 예약녹화시 편리한 더블데크 VTR을 제공하는 것이다 .It is another object of the present invention to provide a convenient double deck VTR for reservation recording.
상기 목적들을 달서아기 위하여 본 고안은 제1 및 제2데크를 구비한 더블데크 VTR에 있어서, 상기 제1데크에 접속되어 상기 제1데크에 의하여 구동되는 테이프의 종단을 검출하기 위한 엔드센서(40) ; 상기 엔드센서(40)로 부터의 테이프 종단 검출신호를 반전시키기 위한 반전수단(50) ; 상기 반전수단(50)으로 부터의 출력신호와 상기 제1데크의 지연녹화 제어신호의 논리상태에 따라 상기 제1데크와 상기 제2데크중 어느 하나를 구동시키기 위한 제어신호를 출력하는 판단수단(60) ; 및 상기 판단수단 (60)으로 부터의 제어신호에 따라 상기 제1데크와 상기 제2데크중 하나의 동작을 제어하기 위한 제어수단(30)을 포함하는 더블데크 VTR을 제공한다.In order to achieve the above object, the present invention is a double deck VTR having a first deck and a second deck, the end sensor 40 for detecting the end of the tape connected to the first deck driven by the first deck ); Inverting means (50) for inverting the tape end detection signal from the end sensor (40); Determination means for outputting a control signal for driving one of the first deck and the second deck in accordance with a logic state of the output signal from the inverting means 50 and the delay recording control signal of the first deck ( 60); And control means 30 for controlling the operation of one of the first deck and the second deck in accordance with a control signal from the determination means 60.
첨부된 도면을 참조하여 본 고안을 보다 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
제1도는 본 고안에 의한 더블데크 VTR의 테이프릴레이 회로도이다.1 is a tape relay circuit diagram of a double deck VTR according to the present invention.
제1도에 있어서, 제1데크(10) 및 제2데크(20)는 제어수단(30), 예컨대 마이콤에 의해 제어되도록 연결되어 있다. 제1데크(10)에 결합된 엔드센서(40)는 제1데크( 10)에 의해 구동되는 테이프의 종단의 투명한 부분을 통해서 입사되는 광을 접수하기 위한 포토트랜지스터(PT)와, 이 포토트랜지스터(PT)의 콜렉터에 구동전압(Vcc)을 공급하기 위한 저항(R1)과 상기 포토트랜지스터(PT)의 에미터출력을 반전하기 위한 저항(R2) 및 트랜지스터(Q1)으로 구성되어 있다. 이 엔드센서(40)의 반전된 출력은 반전수단(50)에 입력된다.In FIG. 1, the first deck 10 and the second deck 20 are connected to be controlled by a control means 30, for example a microcomputer. The end sensor 40 coupled to the first deck 10 includes a phototransistor PT for receiving light incident through the transparent portion of the end of the tape driven by the first deck 10 and the phototransistor. A resistor R1 for supplying a driving voltage Vcc to the collector of PT, a resistor R2 for inverting the emitter output of the phototransistor PT, and a transistor Q1. The inverted output of this end sensor 40 is input to the inverting means 50.
상기 반전수단(50)은 상기 엔드센서(40)의 테이프 종단검출신호인 "L"신호를 받아서 그 출력단자 A에 반전된 신호인 "H"신호를 출력한다. 본 고안의 실시예에서는 상기 반전수단(50)을 저항들(R3∼R5)과 트랜지스터(Q2)로 전류, 전압귀환형 트랜지스터 증폭회로로 구성하고 상기 트랜지스터(Q2)의 에미터출력을 그 출력신호로 한다. 이 출력신호는 판단수단(60)에 공급된다.The inverting means 50 receives the "L" signal which is the tape end detection signal of the end sensor 40 and outputs the "H" signal which is an inverted signal to its output terminal A. In the embodiment of the present invention, the inverting means 50 is composed of a current and voltage feedback transistor amplifying circuit with resistors R3 to R5 and transistor Q2, and emitter output of the transistor Q2 is an output signal thereof. Shall be. This output signal is supplied to the judging means 60.
본 고안의 실시예에서는 상기 판단수단을 제1데크의 지연녹화 제어신호의 "H"상태에서 게이트되는 AND게이트 회로로 구성하고 이 AND게이트 회로(60)의 출력은 상기 제어수단(30)의 테이프 릴레이 입력포트에 공급하도록 연결한다. 따라서, 제어수단(30)에서는 테이프 릴레이 입력포트에 "H"신호인 테이프 릴레이신호가 공급되면 제1데크(10)는 자동정지모드를 수행하도록 하고 제2데크(20)는 자동녹화모드를 수행하도록 하여 계속하여 예약된 프로그램을 제2데크(20)에 장착된 테이프에 녹화되도록 한다.In the embodiment of the present invention, the determining means is composed of an AND gate circuit gated in the " H " state of the delay recording control signal of the first deck, and the output of the AND gate circuit 60 is a tape of the control means 30. Connect to supply relay input port. Therefore, when the tape relay signal, which is the "H" signal, is supplied to the tape relay input port by the control means 30, the first deck 10 performs the auto stop mode and the second deck 20 performs the auto recording mode. The reserved program is continuously recorded on the tape attached to the second deck 20.
이와 같이 구성한 본 고안의 작용 및 효과는 다음과 같다. 먼저 제1데크 및 제2데크에 각각 테이프를 장착하고 제1데크에서는 장착된 테이프의 중간부위에서부터 녹화가능하도록 되어있고 제2데크에서는 테이프의 처음부터 녹화가능하도록 되어있다고 가정한다. 그리고 예약녹화모드로 VTR을 세트시켜 놓으면 예약된 시간에 제1데크를 통하여 제1테이프의 중간부위부터 예약된 프로그램의 녹화가 시작된다. 녹화도중 제1테이프의 종단이 엔드센서(40)에 의해 검출되면 이는 반전수단(50)에 의하여 반전되어 반전수단(50)의 출력단자 A에는 "H"신호가 출력된다.The operation and effects of the present invention configured as described above are as follows. First, it is assumed that the tape is mounted on the first deck and the second deck, respectively, and the first deck is capable of recording from the middle of the mounted tape, and the second deck is capable of recording from the beginning of the tape. When the VTR is set in the reserved recording mode, recording of the reserved program is started from the middle of the first tape through the first deck at the reserved time. When the end of the first tape is detected by the end sensor 40 during the recording, it is inverted by the inverting means 50 so that an "H" signal is output to the output terminal A of the inverting means 50.
이때 판단수단(60)에서는 "H"인 제1데크의 지연녹화 제어신호가 공급된 상태이므로 그 출력단자에는 테이프 릴레이 입력포트에 공급된다. 이에 제어수단(30)은 제1데크(10)를 정지모드로 하고 제2데크(20)를 녹화모드로 하여 제2데크(20)를 통하여 제2테이프에 계속 예약된 프로그램을 녹화하게 된다.In this case, since the delay recording control signal of the first deck of "H" is supplied by the determination means 60, the output terminal is supplied to the tape relay input port. Accordingly, the control means 30 records the program continuously reserved on the second tape through the second deck 20 with the first deck 10 in the stop mode and the second deck 20 in the recording mode.
이상과 같이 본 고안에서는 더블데크를 이용하여 예약녹화시 테이프 부족으로 인한 예약녹화실패를 방지할 수 있다. 따라서, 테이프를 보다 능률적으로 사용가능하게 하며 더블데크 VTR의 장점을 십분 향상시킬 수 있는 것이다.As described above, the present invention can prevent a reservation recording failure due to lack of tape during reservation recording using a double deck. Therefore, the tape can be used more efficiently, and the advantages of the double-deck VTR can be improved by ten minutes.
상술한, 본 고안의 실시예에서는 제1데크에만 테이프 릴레이회로를 결합한 것으로 기술하고 있으나 제2데크에도 결합 가능하다.In the above-described embodiment of the present invention, the tape relay circuit is coupled to only the first deck, but may be coupled to the second deck.
또한, 제1데크 및 제2데크의 각각에 테이프 릴레이회로를 결합하고 제어수단에 각 테이프 릴레이 입력포트를 설정하여 본 고안을 달성할 수도 있음을 유의하여야 한다 .In addition, it should be noted that the present invention may be achieved by coupling a tape relay circuit to each of the first deck and the second deck and setting each tape relay input port to the control means.
