It relates to a recording mode change circuit during scheduled recording.
종래에는 예약녹화를 할 경우에 모우드 선택스위치를 절환하여 녹화모우드를 설정하면, 예약녹화가 안료될때까지 그 설정한 녹화모우드로 영상신호를 녹화하였으므로 예약 녹화시 프로그램의 변동 및 녹화할 영상신호에 따라 사용자가 임의로 녹화모우드를 변경할 수 없어 비디오 데이프를 효율적으로 사용할 수 없는 결함이 있었다.Conventionally, when the recording mode is set by switching the mode selection switch during the scheduled recording, the video signal is recorded in the set recording mode until the reserved recording is pigmented. There was a defect that the video tape could not be used efficiently because the user could not change the recording mode arbitrarily.
본 고안은 이와 같은 종래의 결함을 감안하여, 예약녹화시 임의의 시간에 녹화모우드를 변경하여 영상실호를녹화할 수 있게 안출한 것으로, 이를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.The present invention has been made in consideration of such a conventional defect, it is possible to record a video room by changing the recording mode at any time during the reservation recording, which will be described in detail by the accompanying drawings as follows.
첨부된 도면에 도시한 바와 같이 일측고정단자(al)(a2)가 접지된 녹화모우드스위치(SW1)(SW2)의 타측고정단자(b1)(b2)에 전원단자(Vcc)를 저항(R1)을 통해 접속하여 녹화모우드설정부(1)를 구성하고, 예약 녹화설정신호 및 녹화모우드 변경신호가 입력되는 타이머(2)의 출력단자(Q1)(Q2)를 버퍼(3) 및 기억부(4)의 입력단자에 접속하여, 버퍼(3)의 출력단자를 트랜지스터(TR1)(TR2)의 베이스에 접속하고, 트랜지스터(TR2)의콜렉터에는 상기 녹화모우드설정부(1)의 녹화모우드스위치(SW1) (SW2)의 가동단자를 다이오드(D3) (D4)를 통해 접속하며, 기억부(4)의 출력단자(OT1)(OT2)는 다이오드(D5) (D6)를 통해 트랜지스터(TR3)의 콜렉터에 접속하여 그 접속점을 저항(R2)을 통해 트랜지스터(TRl)의 클렉터 및 트랜지스터(TR3)의 베이스에 접속함과아을러 그 출력단자(OTl)(OT2)를 다이오드(D7)(D8)를 통한 후 마이오드(Dl)(D2)를 통한 상기 녹화모우드스위치(SW1)(SW2)와 함께 녹화모우드신호 출력단자(A)(B)에 접속하여 녹화모우드스위치부(5)를 구성한 것으로, 상기 에서 타이머(2)는 녹화모우드변경신호를 설정한 시간이 되면, 출력단자(Q1)(Q2)로 고전위를 출력하게 하고, 기억부(4)는 타이머(2)의 출력단자(Q2)에서 출력된 고전위가 입력되면, 그의 출력단자(OT1)(OT2)에 녹화모우드- 선정신호로 설정한 녹화모우드신호를 출력하게 한다.As shown in the accompanying drawings, the power supply terminal Vcc is connected to the other fixed terminals b1 and b2 of the recording mode switch SW1 and SW2 to which one fixed terminal al and a2 are grounded. The recording mode setting unit 1 is connected to the output terminal Q1 and Q2 of the timer 2 through which the reserved recording setting signal and the recording mode change signal are inputted. ), The output terminal of the buffer 3 is connected to the base of the transistors TR1 (TR2), and the collector mode of the recording mode setting unit 1 of the recording mode setting unit 1 is connected to the collector of the transistor TR2. The movable terminal of SW2 is connected through the diode D3 and D4, and the output terminal OT1 and OT2 of the storage unit 4 are the collectors of the transistor TR3 through the diode D5 and D6. Connected to the selector of the transistor TRl and the base of the transistor TR3 through the resistor R2, and the output terminal OTl OT2 is connected to the diode D7 and D8. After connecting to the recording mode signal output terminal (A) (B) together with the recording mode switch (SW1) (SW2) through the diode (Dl) (D2) to configure the recording mode switch unit 5, The timer 2 outputs the high potential to the output terminals Q1 and Q2 when the recording mode change signal reaches the set time, and the storage unit 4 outputs the output terminal Q2 of the timer 2 to the output terminal Q1. When the output high potential is input, it outputs the recording mode signal set as the recording mode selection signal to its output terminals OT1 and OT2.
이와 같이 구성된 본 고안의 작용효과를 상세히 설명하면 다음과 같다.Referring to the effect of the present invention configured in this way in detail as follows.
전원단자(Vcc)에 전원이 인가된 상태에서 영상신호를 녹화할 경우에 녹화모우드스위치(SW1)(SW2)를 절환하면, 그 절환에 따라 녹화모우드스위치(SW1)(SW2)의 가동단자 전위는 고전위 또는 저전위로 되어 다이오드(D1)(D2)를 통해 녹화모우드신호 출력단자(A)(B)로 출력되므로 기기는 녹화모우드스위치(SW1)(SW2)를 절환하여 설정한 녹화모우드로 영상신호를 녹화하게 된다.If the recording mode switches SW1 and SW2 are switched when recording a video signal while power is supplied to the power supply terminal Vcc, the movable terminal potential of the recording mode switches SW1 and SW2 is changed according to the switching. The device is output to the recording mode signal output terminal (A) (B) through the diode (D1) (D2) at high potential or low potential, so the device switches the video signal to the recording mode set by switching the recording mode switch (SW1) (SW2). Will be recorded.
그리고, 예약녹화를 하기 위하여 통상의 에약녹화신호인 예약녹화설정신호를 입력시켜 기억시키게 되면, 예약시간이 될매까지 그 기억상태를 유지하게 되고, 녹화모우드를 변경하기 위하여 변경시간 설정신호인 녹화모우드 변경신를 타이머(2)에 입력시키면, 그 타이머(2)에 상기 예약녹화 설정신호를 다시 기억시킬 수 있게된다.When the reserved recording setting signal, which is a normal weak recording signal, is inputted and stored for the reserved recording, the recording state is maintained until the reserved time, and the recording mode which is the changing time setting signal is used to change the recording mode. When the change signal is input to the timer 2, the timer 2 can be stored in the reservation recording setting signal again.
그리고, 기억부(4)에 녹화모우드, 설정신호를 입력시켜 기억시키게 되면 상기 타이머(2)에 기억원 예약녹화설정신호의 설정시간이 되었을때 그 기억부(4)에서 녹화모우드설정신호가 그의 출력단자(OT1, OT2)로 출력된다.When the recording mode and the setting signal are inputted and stored in the storage unit 4, the recording mode setting signal is stored in the storage unit 4 when the set time of the storage source reserved recording setting signal reaches the timer 2. It is output to the output terminals OT1 and OT2.
그런데 상기 변경모우드 설정신호의 변경시간이 되지 않았을 경우에는 타이머(2)의 출력단자(Q1)에 저전위가 출력되고, 이 저전위는 버퍼(3)를 통해 트랜지스터(TR1,TR2)의 베이스에 인가되므로 트탠지스터(TR1)(TR2)는 모두 오프되어 다이오드(D3)(D4)가 오프되고, 이에 따라 녹화모우드스위치(SW1)(SW2)의 선택에 따른 녹화모우드선택신호는 다이오드(D1) (D2)를 통해 녹화모우드신호 출력단자(A)(B)로 출력되여, 또한 이때 기억부(4) 의 출력단자(QT1) (OT2)에서 어느 한 단자라도 고전위가 출력되면, 그 고전위는 다이오드(D5)(D6)를 통하고, 저항(R2)을 통해 트랜지스터(TR3)의 베이스에 인가되어 그가 온되므로 기억부(4)의 출력단자(○T1) 또는(OT2)에서 출력된 고전위는 다이오드-(D5)(D6)를 통하고, 트랜지스터(TR3)를 통해 접지로 흐르게 되며, 녹화모우드-신호 출력단자(A)(B)에는 상기와 같이 스위치(SW1)(SW2)의 선택에 따른 녹화모우드선택 신호가 출력되어 기기는 그 스위치(SW1)(SW2)의 절환에 따라 설정한 녹화모우드로 영상신호를 녹화하게 된다.However, when the change time of the change mode setting signal is not reached, the low potential is output to the output terminal Q1 of the timer 2, and the low potential is transmitted to the base of the transistors TR1 and TR2 through the buffer 3. Since the transistors TR1 and TR2 are all turned off, the diodes D3 and D4 are turned off. Accordingly, the recording mode selection signal according to the selection of the recording mode switches SW1 and SW2 is converted to the diode D1 ( D2) is output to the recording mode signal output terminal (A) (B), and at this time, if any terminal is output at the output terminal (QT1) (OT2) of the storage unit 4, the high potential is The high potential output from the output terminal (○ T1) or (OT2) of the storage section 4 is applied to the base of the transistor TR3 through the diodes D5 and D6 and applied to the base of the transistor TR3 through the resistor R2. Is passed through the diode (D5) (D6), through the transistor (TR3) to ground, and to the recording mode signal output terminal (A) (B) As described above, the recording mode selection signal according to the selection of the switches SW1 and SW2 is output, so that the device records the video signal in the recording mode set according to the switching of the switches SW1 and SW2.
이와 같은 상태에서 일정시간이 경과하여 녹화모우드 변경신호로 설정한 시간이 되면, 타이머(2)의 출력단자(Q1)(Q2)에서 고전위가 출력되어 버퍼(3) 및 기억부(4)에 입력되므로 버퍼(3)의 출력단자에는 고전위가 출력되어 트랜지스터(TR1) (TR2)의 베이스에 인가되고, 이에 따라 트랜지스터(TR1) (TR2) 가 모두 온되므로 녹화모우드스위치(SW1)(SW2)의 가동단자의 전위는 다이오드(D3)(D4)를 통하고, 트랜지스터(TR2)를 통해 접지로 흐르게 되며, 트랜지스터(TR3)의 베이스 전위는 저전위로 되어 그가 오프된다.In this state, when a predetermined time has elapsed and the time set as the recording mode change signal is reached, a high potential is output from the output terminals Q1 and Q2 of the timer 2 to the buffer 3 and the storage unit 4. Since it is input, a high potential is output to the output terminal of the buffer 3 and applied to the base of the transistors TR1 and TR2. Accordingly, since the transistors TR1 and TR2 are all turned on, the recording mode switches SW1 and SW2 are turned on. The potential of the movable terminal of is passed through the diodes D3 and D4, and flows to the ground through the transistor TR2, and the base potential of the transistor TR3 becomes low and is turned off.
따라서, 기억부(4)에 기억되어 있는 녹화모우드 설정신호가 그의 출력단자(OT1)(OT2)로 출력되어 다이오드(D7) (D8)를 통해 녹화모우드신호 출력단자(A)(B)로 출력되므로 기기는 녹화모우드설정신호로 설정한 녹화모우드를 영상신호를 녹화하게 된다.Therefore, the recording mode setting signal stored in the storage section 4 is output to its output terminals OT1 and OT2, and outputs to the recording mode signal output terminals A and B through the diodes D7 and D8. Therefore, the device records the video signal of the recording mode set as the recording mode setting signal.
이상에서 설명한 바와 같이 본 고안은 에약녹화를 할경우에 원하는 시간에 녹화모우드를 변경하여 녹화할수 있으므로 사용자가 녹화할 프로그램에 따라 녹화모우드를 변경할 수 있음은 물론 비디오 테이프를 효율적으로 사용할 수 있는 효과가 있다.As described above, the present invention can change the recording mode at a desired time in case of weak recording, so that the user can change the recording mode according to the program to be recorded as well as the effective use of video tape. have.
