본 고안은 VTR의 예약녹화시간 도중에 테이프를 재생시킴에 있어서 테이프 재생이 완료됨과 동시에 재생모드(P.B Mode)에서 타임모드(Time mode)로 자동전환되면서 예약된 시간에 녹화를 수행할 수 있도록 한 타이머(Timer)의 스탠드바이(Stand-by)유지장치에 관한 것이다.In the present invention, when the tape is played during the scheduled recording time of the VTR, a timer is provided so that recording can be performed at the scheduled time by automatically switching from the PB mode to the time mode at the same time as the tape playback is completed. (Stand-by) holding device of (Timer).

종래의 경우, VTR을 이용하여 예약녹화를 수행하기 위하여 설정된 시간도중 사용자가 테이프를 재생시키고자 하여 VTR에 테이프를 장착, 재생모드를 수행시켜 재생완료한 후에는 다시 타임머스위치(Timer switch)를 ON시켜야만이 예약된 시간에 녹화를 수행할 수가 있게되는데, 이때 사용자의 부주의로 인해 타이머스위치를 누르지 않고 전원차단스위치를 off시킬경우가 발생되면 설정된 예약녹화시간이 해제되어 할수가 없는등의 결점이 있었다.In the conventional case, a user inserts a tape into the VTR to play a tape during the set time to perform a reservation recording using the VTR, executes the play mode, and then presses the timer switch again. Only when it is turned ON, recording can be performed at the scheduled time, but if the user turns off the power switch without pressing the timer switch due to user's carelessness, it is impossible to set the scheduled recording time. there was.

따라서 본 고안은 상기와 같은 종래의 결점을 해소시키기 위해서 VTR의 예약녹화시간중에 테이프를 재생시켜, 수행완료됨과 동시에 자동으로 타이머가 구동되어 예약녹화를 수행할 수 있도록 안출된것으로 첨부된 도면에 의하여 그 구성과 작용효과를 상세히 설명하면 다음과 같다.Accordingly, the present invention is designed to relieve the above-mentioned drawbacks, and play the tape during the reservation recording time of the VTR, and at the same time, the timer is automatically driven to make the reservation recording. The configuration and the effect of the operation are described in detail as follows.

제1도는 본 고안의 회로도로서 예약녹화시간 설정후 키매트릭스(key matrix)(1)의 타이머스위치(T.SW) "ON"동작에 의해 마이컴(Micom)에서 출력되는 신호를 일시적으로 기억하여 출력시킬 수 있도록 쉬미트트리거(Schmidt trigger)(S), 콘덴서(C1), 저항(R1) 및 플립플롭(flip-flop)(FF)으로 이루어진 기억부(2)와, 마이컴(Micom)에서 출력된 파워(Power)신호를 받아 출력시키는 저항(R2-R5), 트랜지스터(TR1, TR2)로 이루어진 제어부(3)와 상기 기억부(2)와 제어부(3)의 출력신호를 비교출력하여 타이머마이컴(Timer Micom)에 인가시켜 타이머를 구동시킬 수 있도록 AND게이트(AND), 저항(R6, R7), 트랜지스터(TR3), OR게이트(OR)로 이루어진 타이머구동부(4)로 구성된 것으로 미설명부호 OUT. T와 OUT. P는 마이컴(Micom)의 출력단인 것이다.FIG. 1 is a circuit diagram of the present invention. After setting a reserved recording time, the signal output from the micom is temporarily stored by the timer switch (T.SW) " ON " of the key matrix (1). In the memory unit 2 consisting of a Schmidt trigger (S), a capacitor (C 1 ), a resistor (R 1 ) and a flip-flop (FF), and a micom The control unit 3 comprising the resistors R 2 -R 5 and transistors TR 1 and TR 2 for receiving and outputting the output power signal, and output signals of the storage unit 2 and the control unit 3. Timer driver (4) consisting of AND gate (AND), resistors (R 6 , R 7 ), transistor (TR 3 ), OR gate (OR) for comparison output and applied to timer micom to drive timer. ) And the notation code OUT. T and OUT. P is the output of Micom.

이와같이 구성된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention configured as described above are as follows.

VTR을 이용 예약녹화를 위한 예약녹화시간을 설정한후 키매트릭스(1)의 타이머스위치(T. SW)을 ON동작시키면, 마이컴(Micom)의 출력단(OUT. T)에서 high레벨상태의 신호가 출력되어 기억부(2)의 쉬미트트리거(S), 콘덴서(C1), 저항(R1), 다이오드(D1)를 통해 플립플롭(FF)에 임의시간 동안 기억되면서 예약된 녹화시간이 진행된다.When the timer switch (T. SW) of the key matrix (1) is turned ON after setting the reservation recording time for the reservation recording using the VTR, a high level signal is output from the output terminal (OUT.T) of the micom. It is output and stored in the flip-flop (FF) for a predetermined time through the Schmitt trigger (S), the capacitor (C 1 ), the resistor (R 1 ), the diode (D 1 ) of the storage unit 2 is reserved recording time Proceed.

이와같은 상태 VTR에서 예약녹화를 수행하기 위해서 설정된 시간이 흐르고 있는 상태에서 사용자가 테이프를 재생시키기 위해 파워(Power)을 ON할 경우, 설정된 예약녹화시간은 해제가 됨과 동시에 VTR는 테이프 재생모드기능을 일정시간동안 수행하게 되어 테이프재생이 완료된후, 사용자가 부주의로 타이머스위치를 누르지 않고 전원을 차단시킬 경우에는 마이컴(Micom)의 출력단(OUT.P)에서 "Low"레벨상태의 신호가 제어부(3)로 출력되어 저항(R2), 트랜지스터(TR1)를 통해 트랜지스터(TR2)의 콜렉터단에서 "High"레벨상태의 신호가 출력되면서, 예약녹화시간이 입력되어 있는 기억부(2)의 플립플롭(FF), 출력단(Q)이 일측에 연결되어 있는 구동부(4)의 AND게이트(AND)에 인가됨에 따라 즉, 기억부(2)및 제어부(3)로부터 AND게이트(AND)에 인가되는 출력이 각각 High레벨상태의 신호이므로 AND게이트(AND)의 출력은 High레벨상태의 신호로 되어 저항(R6)을 통해 트랜지스터(TR3)의 베이스단에 인가되면서 트랜지스터(TR3)의 에미터단을 통하여 OR게이트(OR)의 일측단으로 인가되고, OR게이트(OR)의 입력단 타측에는 키매트릭스(1)의 타이머스위치(T. SW)신호가 인가되어 OR게이트(OR)에서 타이머 구동신호를 출력시켜 마이컴으로 인가시켜주면 타이머는 다시 구동되어 설정된 시간이 되면 마이컴은 "REC"(녹화모드)신호를 출력하여 예약된 시간에 사용자가 원하는 녹화를 수행하게 된다.In this state, if the user turns on the power to play the tape while the set time has elapsed in order to perform the reservation recording in the state VTR, the set reservation recording time is released and the VTR operates the tape playback mode function. After the tape playback is completed for a certain period of time, and the user inadvertently shuts off the power without pressing the timer switch, the signal of the "Low" level state is output from the output terminal OUT of the Micom. ) Is outputted to the collector terminal of the transistor TR 2 through the resistor R 2 and the transistor TR 1 , and the signal of the high level state is outputted. As the flip-flop FF and the output terminal Q are applied to the AND gate AND of the driving unit 4 connected to one side, that is, the storage unit 2 and the control unit 3 are applied to the AND gate AND. Output level is high The output of the AND gate AND is a high level signal and is applied to the base terminal of the transistor TR 3 through the resistor R 6 while the OR gate OR is applied through the emitter terminal of the transistor TR 3 . ) Is applied to one side of the OR gate (OR), the timer switch (T. SW) signal of the key matrix 1 is applied to the other side of the input terminal of the OR gate (OR) to output a timer driving signal from the OR gate (OR) to the microcomputer If the timer is restarted and the set time is reached, the microcomputer outputs the "REC" (recording mode) signal and performs the recording desired by the user at the scheduled time.

이상에서 본 바와같이 본 고안은 VTR의 예약녹화시간 도중에 테이프재생모드를 수행, 완료한후 자동적으로 타이머 수행모드로 전환되면서 타이머가 구동되어 설정된 시간이 되면 예약녹화기능을 수행하므로 사용이 편리함등의 장점이 있다.As seen above, the present invention performs the tape play mode during the reserved recording time of the VTR, and automatically switches to the timer execution mode after completion of the timer. There is an advantage.
