본 고안은 비디오 테이프 레코오더의 비디오 테이프에 영상 신호를 편집(Editing)기록하는 편집장치에 관한것으로, 특히 디지탈 카운터를 이용하여 편집하게 한 비디오 테이프 레코오더의 편집장치에 관한 것이다.The present invention relates to an editing apparatus for editing and recording an image signal on a video tape of a video tape recorder, and more particularly, to an editing apparatus for a video tape recorder, which is edited using a digital counter.

종래의 편집장치는 제1도의 타이밍도에 도시한 바와같이 일정기간(T1)동안 비디오 테이프에 영상신호를 기록한 후 시간(t1)에 일시정지시키면, 시스템 콘트롤러에 의해 일정시간(T2)동안 모우터의 구동을 정지시킨 후 곧이어 다음 기간(T3)동안 모우터에 역 전압을 인가하여 비디오 테이프의 되감기를 하면서 그 기간(T3)동안의 콘트롤 펄스의 수를 카운트하고, 시간(t2)에 비디오 테이프 레코오더를 일시정지상태로 만든다.In the conventional editing apparatus, as shown in the timing diagram of FIG. 1 , if a video signal is recorded on a video tape for a predetermined time T 1 and then paused at a time t 1 , the system controller makes a predetermined time T 2 by the system controller. Immediately after the motor is stopped for the next time T 3 , a reverse voltage is applied to the motor to rewind the video tape, counting the number of control pulses during the time T 3 , and time t 2 ) Pause the video tape recorder.

여기서, 일정기간(T3)동안 비디오 테이프를 되감기하는 이유는 비디오 테이프의 트랙이 헬리컬상으로 경사져있어 곧 바로 다음의 영상 신호를 기록 할 수 없으므로 15-20프레임(frame)정도 되감기 한 후 다음의 영상신호가 기록될 트랙을 이미 녹화된 트랙의 다음 트랙부터 사작하기 위한 것이다.The reason why the video tape is rewound for a certain period of time (T 3 ) is that the track of the video tape is helically tilted so that the next video signal cannot be recorded immediately. This is for starting the track where the video signal is to be recorded from the next track after the already recorded track.

그리고, 일정기간(T4)이 경과하고, 시간(t3)에 일시정질 해제하면, 시스템 콘트롤러에 의해 비디오 테이프 레코오더는 재생모우드로 되면서 일정기간(T5) 즉, 카운트된 콘트롤 펄스의 수가 검출될 때까지 비디오 테이프 레코오더 기록된 영상신호를 재생한 후 다음기간(T6)에 영상신호가 기록되지 않은 다음 트랙부터 수직동기신호에 의해 영상신호를 기록하기 시작한다.After a certain period of time T 4 has elapsed and at a time t 3 , the video tape recorder enters the playback mode by the system controller while the number of control pulses counted for a certain period of time T 5 . a reproducing the video signal recorded video tape recorder order until after detection and the next track is not the video signal recorded in the period (T 6) starts recording a video signal by a vertical synchronizing signal.

그러나, 이와같은 종래의 편집장치는 반드시 콘트롤 펄스만을 이용해야 되는 결함이 있었다.However, such a conventional editing apparatus has a defect in that only a control pulse must be used.

본 고안은 이와같은 종래의 결함을 감안하여, 콘트롤 펄스를 사용하지 않고, 카운터를 이용하는 간단한 구성의 편집장치를 안출한 것으로, 이를 첨부된 제2도의 도면에 의하여 상세히 설명하면 다음과 같다.The present invention, in view of such a conventional defect, devised a simple configuration of the editing device using a counter without using a control pulse, which will be described in detail with reference to the accompanying drawings of FIG.

It is connected to the input terminal of NAND 1 through the oragate (ExOR 0 , ExOR 1 , ...., ExOR N ), and the output side of the AND (AND 1 ) is connected to the system controller (1). Through the mono-multi (5) (6) through one side and the other fixed terminal (a 2 ) (b 2 ) of the electronic switch (SW 2 ) to which the control signal terminal (S 3 ) of Accessing and connecting to the movable terminal of the electronic switch (SW 2) of the control Shiho terminal (S 2) of the system controller 1, the movable terminal to the control terminal connection (SW 3) of the electronic switch (SW 3) One side and the other fixed terminal (a 3 ) (b 3 ) of the other fixed terminal (b 4 ) and the other terminal of the electronic switch (SW 4 ) in which the control terminal is connected to the control signal terminal (S 1 ) of the system controller (1) and It is connected to the input terminal of the servo circuit 7, respectively, and the movable switch SW 4 is connected to the latch terminal LP of the latch 4, and the fixed terminal a 4 is provided with a synchronization signal terminal ( VS is connected to each other. In the above, the electronic switch SW 1 causes the short circuit by applying a high potential to the control terminal by the system controller 1 during recording mode, and the up-down counter 3 is connected to the system controller 1. By applying high potential to UP terminal during recording mode, it operates as up counter and recording mode By applying a high potential to the down terminal (DO) when the pause operation and presented to the down-counter, the electronic switch (SW 2 -SW 4) is fixed to one side to be applied with the low potential movable terminal at the time of pause of the recording The mode control terminal Short the terminals (a 2-a 4 ).

이와같이 구성된 본 고안 편집장치의 작용효과를 상세히 설명하면 다음과 같다.If described in detail the operation and effect of the present invention the editing apparatus configured as described above.

비디오 테이프 레코오더의 기록모우드시 시스템 콘트롤러(1)의 제어단자(S1)(S2)(S3)에 고전위가 출력되어 전자스위치(SW2)(SW3)(SW4)의 가동단자가 타측 고정단자(b2)(b3)(b4)에 단락되고, 또한 출력단자(Q1)(Q2)의 출력신호로 로직게이트(2)의 출력단자(Y1)(Y2)에 고전위가 출력되어 전자스위치(SW1)가 단락되게 함과 아울러 업다운카운터(3)가 업카운터로 동작되게 하면, 업다운카운터(3)전자스위치(SW1)를 통해 그의 클럭단자(CK)에 인가되는 클럭신호 단자(CLK)의 클럭신호를 가산 카운트하고,Operation of the tape control terminal of the records recorded in the order modal when the system controller (1) (S 1) ( S 2) is a high potential output on the (S 3) an electronic switch (SW 2) (SW 3) (SW 4) The terminal is short-circuited to the other fixed terminal (b 2 ) (b 3 ) (b 4 ), and the output terminal (Y 1 ) (Y) of the logic gate (2) by the output signal of the output terminal (Q 1 ) (Q 2 ). When the high potential is output to 2 ) and the electronic switch SW 1 is short-circuited and the up-down counter 3 is operated as an up counter, its clock terminal (3) is provided through the up-down counter 3 electronic switch SW 1 . The clock signal of the clock signal terminal CLK applied to CK is added and counted,

그 카운트된 수는 전자스위치(SW4)를 통해 래치(4)의 래치단자(LP)에 인가되는 동기신호단자(VS)의 동기 신호에 따라 래치(4)에 입력되어 저장되며, 또한 모노멀티(6)에는 30Hz 의 신호가 출력되고, 그 출력된 30Hz신혼는 전자스위치(SW2)(SW3)를 통해 서어보회로(7)에 입력되어 모우터를 제어한다.The counted number is input to and stored in the latch 4 in accordance with the synchronization signal of the synchronization signal terminal VS applied to the latch terminal LP of the latch 4 through the electronic switch SW 4 , and is also mono-multi. A signal of 30 Hz is output to (6), and the output 30 Hz honeymoon is input to the servo circuit 7 through an electronic switch SW 2 (SW 3 ) to control the motor.

이와같은 상태에서 기록모우드의 일시정지상태가 되면, 시스템 콘트롤러(1)에 의해 구동을 정지시킨 후 역전압을 인가시켜 역구동시키면서 되감기를 시작함과 아울러 시스템 콘트롤러(1)에 의해 업다운카운터(3)의 다운단자(DO)에 고전위를 인가하여 다운카운터로 동작하게 하고, 또한 전자스위치(SW2-SW4)의 제어단자에 저전위를 인가하여 가동단자가 일측고정단자(a2-a4)에 각기 단락되므로 업다운카운터(3)는 전자스위치(SW1)를 통해 그의 클럭단자(CK)로 인가되는 클럭신호단(CLK)의 클럭신호를 감산하고, 이때 업다운카운터(3)감산카운트된 수가 래치(4)에 저장된 수와 일치되면, 익스클루시브 오아게이트(ExOR0,ExOR1,....,ExORN)의 출력측에 모두 저전위가 출력되어 낸드게이트(NAND1)의 입력단자에 각기 인가되므로 낸드게이트(NAND1)의 출력측에는 고전위가 출력되어 모노멀티(5)의 입력단자에 인가되고, 이에 따라 모노멀티(5)의 출력단자에는 고전위가 출력되어 시스템 콘트롤러(1)가 출력되는 고전위의 수를 카운트함과 아울러 그 고전위가 전자스위치(SW2-SW4)를 통해 래치(4)의 래치단(LP)에 인가되므로 래치(4)에는 계속 동일한 수가 저장된다.In this state, when the recording mode is in the pause state, the system controller 1 stops driving and starts reverse rewinding while applying reverse voltage to reverse drive and up-down counter 3 by the system controller 1. A high potential is applied to the down terminal (DO) of the C1) to operate as a down counter, and a low potential is applied to the control terminal of the electronic switch (SW 2 -SW 4 ) so that the movable terminal is fixed at one side of the terminal (a 2 -a). 4 ) the up-down counter 3 subtracts the clock signal of the clock signal terminal CLK applied to the clock terminal CK thereof through the electronic switch SW 1 , and at this time, the up-down counter 3 subtracts the counter. When the number is matched with the number stored in the latch 4, the low potential is output to the output side of the exclusive oragate (ExOR 0 , ExOR 1 ,..., ExOR N ) so that the input of the NAND gate NAND 1 applied to each terminal, so the output side of the NAND gate (NAND 1) and The potential is output and applied to the input terminal of the monomulti 5, so that a high potential is output to the output terminal of the mono multi 5 so that the system controller 1 counts the number of high electric potentials to be output. the high potential is applied to the latch stage (LP) of the latch (4) through the electronic switch (SW 2 -SW 4), because the latch (4) is still the same number of storage.

여기서, 업다운카운터(3)의 카운트 속도는 상기와 동일하게 하고, 모노멀티(5)는 30Hz의 주기로 고전위를 출력하게 그이 시정수를 조절한다.Here, the count rate of the up-down counter 3 is the same as above, and the monomulti 5 adjusts its time constant to output a high potential at a period of 30 Hz.

그리고, 일정시간이 경과하여 되감기를 중지하고, 그 되감기를 하는 기간동안 시스템 콘트롤러(1)가 모노멀티(5)에서 출력되는 30Hz의 고전위 수를 카운트한 상태에서 기록모우드의 일시정지가 해제되면, 시스템 콘트롤러(1)는 비디오 테이프 레코오더를 재생시키면서 업다운카운터(3)를 업카운터로 동작시켜 클럭신호단자(CLX)의 클럭신호를 카운트하고, 또한 전자스위(SW2-SW4)의 가동단자를 타측 고정단자(b2-b4)에 각기 단락시켜 동기신호단자(VS)의 동기신호에 따라 업다운카운터(3)의 카운트된 수를 래치(4)에 입력저장하고, 서어보회로(7)에는 모노멀티(6)에서 출력되는 30Hz의 신호가 전자스위(SW2)(SW3)를 통해 입력되어 모우터의 구동을 제어하며, 이때 시스템 콘트롤러(1)는 모노멀티(6)에서 출력되는 30Hz 신호의 고전위를 카운트하여 그 카운트된 수가 상기의 되감기시 모노멀티에서 출력된 30Hz 신호의 고전위수와 일치될 때 비디오 테이프 레코오더를 기록 모우드로 만들어 영상신호를 기록시킨다.When the rewinding stops after a certain time, and the pause of the recording mode is released while the system controller 1 counts the high frequency of 30 Hz output from the monomulti 5 during the rewinding period. The system controller 1 operates the up-down counter 3 as an up counter while reproducing the video tape recorder to count the clock signal of the clock signal terminal CLX, and also operates the electronic switch SW 2 -SW 4 . The terminals are short-circuited to the other fixed terminals b 2- b 4 , respectively, and input and store the counted number of the up-down counters 3 in the latch 4 according to the synchronization signal of the synchronization signal terminal VS, and the servo circuit ( 7) 30Hz signal output from the mono-multi (6) is input through the electronic switch (SW 2 ) (SW 3 ) to control the driving of the motor, wherein the system controller (1) at the mono-multi (6) Count the high potential of the output 30Hz signal and count the number When the match classical percentile of the 30Hz signal output from the mono-multi during the rewinding of writes a video signal to create a video tape recorder to the recording order modal.

이상에서 설명한 바와같이 본 고안은 업다운카운터를 이용하는 편집장치로 종래와같이 반드시 콘트롤펄스를 이용해야 되는 필요성을 배제할 수 있는 효과가 있다.As described above, the present invention has an effect of eliminating the necessity of using a control pulse as a conventional editing apparatus using an up-down counter.
