제2도의 (a)에 도시한 바와 같이 비디오헤드가 비디오 트랙과 일치하지 않을 때(b), (c)에 따라 비디오트랙에 대해 비디오헤드를 우측 또는 좌측으로 움직여 (a)의 경우와 같이 일치되도록 트래킹을 해야 한다. 그러나 일반적으로 트래킹 동작이 우측 또는 좌측으로 되고 있는지와 트래킹 상태, 즉 우측 또는 좌측으로 어느정도 되었는지를 알 수 없이 리모콘으로 트래킹을 할 때 불편한 점이 많았다.As shown in (a) of FIG. 2, when the video head does not coincide with the video track (b), the video head is moved to the right or left side with respect to the video track according to (c) to match as in the case of (a). You should track as much as possible. However, in general, there were many inconveniences when tracking with a remote controller without knowing whether the tracking operation is going to the right or left and the tracking state, that is, to the right or left.
이러한 불편함을 없애기 위하여, 본 고안은 트래킹 동작방향 및 상태를 사용자가 눈으로 쉽게 확인할 수 있도록 안출한 것으로서, 이를 첨부한 도면을 이용하여 상세히 설명하면 다음과 같다.In order to eliminate this inconvenience, the present invention is designed to make the user can easily check the tracking operation direction and state, described in detail using the accompanying drawings as follows.
제1도는 본 고안의 트래킹 동작 및 상태 표시회로도로서, 이에 도시한 바와같이 마이콤(3)의 좌측 및 우측 출력포트(PL)(PR)를 좌측 및 우측동작 표시부(42),(41)에 각기 접속함과 아울러, 상기 마이콤(3)의 우측 출력포트(PR)를 다이오드(D1)를 통해 우측 적분부(51) 및 좌측신호 뮤팅부(61)의 입력측과 공통접속하고, 상기 마이콤(3)의 좌측 출력포트(PL)를 다이오드(D3)를 통해 좌측 적분부(52) 및 우측신호 뮤팅부(62)의 입력측과 공통접속하여 상기 우측적분부(51)와 우측신호 뮤팅부(61) 출력측의 접속점 및 좌측적분부(52)와 좌측신호뮤팅부(62)출력측의 접속점을 다이오드(D8),(D7)를 각기 통해 우측 및 좌측상태 표시부(71), (72)의 입력측에 접속하여 구성한 것으로, 상기 좌측 및 우측상태 표시부(72), (71)의 비교기(CP5-CP8), (CP1-CP4)에는 저항(R21-R24), (R13-R16)으로 분압된 기준전압이 인가되고, 좌측 및 우측동작표시부(42)(41)의 발광다이오드(LED9), (LED10) 색깔은 좌, 우측 동작을 구별하기 위해 다르게 하며, 상기 도면중 미설명부호 SWA는 좌측동작키이, SWB는 우측동작키이이다.FIG. 1 is a tracking operation and status display circuit diagram of the present invention, and as shown therein, the left and right output ports P L (P R ) of the microcomputer 3 have left and right operation display parts 42 and 41. And the right output port P R of the microcomputer 3 are commonly connected to the input side of the right integrating unit 51 and the left signal muting unit 61 through the diode D 1 . The left output port P L of the microcomputer 3 is commonly connected to the input side of the left integrating unit 52 and the right signal muting unit 62 through the diode D 3 to connect the right integrating unit 51 and the right signal. The connection point on the muting section 61 output side and the connection point on the left integrating unit 52 and left signal muting section 62 output side are connected to the right and left status display sections 71 and 72 through diodes D8 and D7, respectively. The comparator (CP 5 -CP 8 ) and (CP 1 -CP 4 ) of the left and right status display sections 72, 71 are connected to the input side of the resistors (R 21 -R 24 ), (R 13 -R The reference voltage divided by 16 ) is applied, and the colors of the light emitting diodes LED9 and LED10 of the left and right operation indicators 42 and 41 are different to distinguish the left and right operations, which are not described in the drawings. The symbol SWA is the left operation key, and the SWB is the right operation key.
이와같이 구성한 본 고안의 작용 및 효과를 첨부한 도면을 이용하여 상세히 설명하면 다음과 같다.If described in detail with reference to the accompanying drawings the operation and effects of the present invention as follows.
트래킹을 우측으로 하기위해 리모콘(1)의 우측동작키이(SWB)를 누르면 그에서 발생하는 신호가 수광부(2)를 통해 마이콤(3)에 인가되어 그의 우출력포트(PR)에서 트래킹동작 정도에 따른 레벨의 신호가 출력된다. 이 출력신호에 의해 다이오드(D9)가도통되고 트랜지스터(Q7)가 온되며 트랜지스터(Q8)가 온되어 발광 다이오드(LED9)가 점등된다. 또한 이때 마이콤(3)의 우출력포트(PR)에서 출력되는 여러 레벨의 신호는 다이오드(D1)를 통해 트랜지스터(Q1)의 베이스에 인가되어 그가 온되며 트탠지스터(Q2)가 온됨에 따라 다이오드(D2) 및 저항(R4)을 통해 캐패시터(C1)에 인가된다.When the right operation key (SWB) of the remote controller 1 is pressed to make the tracking to the right, the signal generated therefrom is applied to the microcomputer 3 through the light receiving unit 2 and the tracking operation degree at the right output port P R thereof . A signal of the level corresponding to the signal is output. The diode D 9 is turned on by the output signal, the transistor Q 7 is turned on, the transistor Q 8 is turned on, and the light emitting diode LED 9 is turned on. In addition, at this time, the signal of various levels output from the right output port P R of the microcomputer 3 is applied to the base of the transistor Q 1 through the diode D 1 so that it is turned on and the transistor Q 2 is turned on. And is applied to capacitor C 1 via diode D 2 and resistor R 4 .
따라서 상기 캐패시터(C1)는 충전되며, 그 충전전압은 다이오드(D8)를 통해 비교기(CP1-CP4)의 반전입력단자에 인가되므로 트래킹 동작 정도에 따라, 즉 우측으로 많이 조정할수록 높은 레벨의 신호가 마이콤(3)의 우출력포트(PR)에서 출력되므로 이에따라 비교기(CP1), (CP2), (CP3), (CP4)의 출력단자는 이 순서대로 저전위상태가 되어 우측으로의 트래킹 상태를 표시하는 발광다이오드(LED1), (LED2), (LED3), (LED4)가 점등된다. 또한 이때 리모콘(1)의 우측작동작키이(SWB)를 간헐적으로 누르면 상기 캐패시터(C1)의 충전전압이 다이오드(D8)를 통해 방전 되었다가 다시 충전되므로 상기 발광다이오드(LED1), (LED2), (LED3), (LED4)의 점등상태가 유지되나다.Accordingly, the capacitor C 1 is charged, and the charging voltage is applied to the inverting input terminals of the comparators CP 1- CP 4 through the diode D 8 , and accordingly, the higher the adjustment is made to the right, the higher the tracking operation. Since the signal of the level is output from the right output port (P R ) of the microcomputer (3), the output terminals of the comparators (CP 1 ), (CP 2 ), (CP 3 ), and (CP 4 ) accordingly have low potential in this order. The light emitting diodes (LED 1 ), (LED 2 ), (LED 3 ), and (LED 4 ) indicating the tracking status to the right side light up. In addition, when the right operation key (SWB) of the remote controller 1 is intermittently pressed, the charging voltage of the capacitor C 1 is discharged through the diode D 8 and then recharged, so that the light emitting diodes LED 1 , ( LED 2 ), (LED 3 ) and (LED 4 ) remain lit.
그 후에 트래킹을 좌측으로 하기위해 리모콘(1)의 좌측 동작키이를 누르면 트래킹 동작정도에 따른 여러레벨의 신호가 마이콤(3)의 좌출력포트(P2)로 출력되어 그 신호가 다이오드(D10)를 통해 트랜지스터(Q9)의 베이스에 인가되어 그가 온됨에 따라 트랜지스터(Q10)가 온되므로 발광다이오드(LED1)가 점등된다. 한편 마이콤(3)의 우출력포트(PR)에서 신호가 출력되지 않으므로 다이오드(D9)가 도통되지 않아 트랜지스터(Q7)가 오프되며 그에 따라 트랜지스터(Q8)가 오프되어 발광다이오드(LED9)가 소등된다.Thereafter, when the left operation key of the remote controller 1 is pressed to turn the tracking to the left, signals of various levels according to the tracking operation degree are output to the left output port P 2 of the microcomputer 3 and the signal is output to the diode D 10. ) it is applied to the base of the transistor (Q 9) through the lights a light emitting diode (LED 1) since the transistor (Q 10) as he came on. On the other hand, since the signal is not output from the right output port P R of the microcomputer 3, the diode D 9 is not conducting and the transistor Q 7 is turned off. Accordingly, the transistor Q 8 is turned off and thus the light emitting diode LED is turned off. 9 ) is turned off.
또한 상기 마이콤(3) 좌출력포트(PL)의 출력신호는 다이오드(D3)를 통해 트랜지스터(Q3)의 베이스에 인가되므로 그가 온되어 캐패시터(C1)의 충전전압이 다이오드(D4)를 통해 방전되며 다이오드(D8)가 도통되지 못해 우측으로의 트래킹 상태를 표시하는 발광다이오드(LED1-LED4)가 소등됨과 아울러, 상기 출력신호가 트랜지스터(Q4)의 베이스에 인가되므로 그가 온되며 트랜지스터(Q5)가 온되고, 이의 에미터로 출력되는 신호는 다이오드(D5) 및 저항(R10)을 통해 캐패시터(C2)에 인가된다.In addition, since the output signal of the left output port P L of the microcomputer 3 is applied to the base of the transistor Q 3 through the diode D 3 , it is turned on so that the charging voltage of the capacitor C 1 is changed to the diode D 4. Since the light emitting diodes (LED 1- LED 4 ) are discharged through the diode D 8 and the LED D 8 is not turned on, indicating the tracking state to the right, the output signal is applied to the base of the transistor Q 4 . It is on and transistor Q 5 is on and the signal output to its emitter is applied to capacitor C 2 via diode D 5 and resistor R 10 .
그러므로 그 캐패시터(C2)가 충전되며 그 충전전압은 다이오드(D7)를 통해 비교기(CP5-CP8)의 반전입력단자에 인가되어 트래킹을 우측으로 할 때와 같이, 좌측으로의 트래킹의 정도에 따라 상기 비교기(CP5), (CP6), (CP7), (CP8)의 출력단자가 순차적으로 저전위상태가 되므로 이에 의해 좌측으로 트래킹 상태를 표시하는 발광다이오드(LED5), (LED6), (LED7), (LED8) 가 점등된다. 이때 리모콘(1)의 좌측동작키이(SWA)를 간헐적으로 눌러도 캐패시터(C2)의 충전전압에 의해 상기 발광다이오드(LED5-LED8)의 점등상태가 유지된다.Therefore, the capacitor C 2 is charged, and the charging voltage is applied to the inverting input terminal of the comparators CP 5- CP 8 through the diode D 7 so that the tracking on the left side can be performed. According to the degree, the output terminals of the comparators CP 5 , CP 6 , CP 7 , and CP 8 sequentially become a low potential state, whereby a light emitting diode (LED 5 ) indicating a tracking state to the left by this, (LED 6 ), (LED 7 ), (LED 8 ) light up. At this time, even if the left operation key SWA of the remote controller 1 is intermittently pressed, the lighting state of the light emitting diodes LED 5 to LED 8 is maintained by the charging voltage of the capacitor C 2 .
다시 우측으로 트래킹을 하게되면 마이콤(3)의 우출력포트(PR)에서 출력되는 신호가 다이오드(D1)를 통해 트랜지스터(Q8)의 베이스에 인가되어 그가 온되므로 캐패시터(C2)의 충전전압이 다이도드(D6)를 통해 방전되며 상기 발광다이오드(LED5-LED8)는 소등되는 동시에, 마이콤(3)의 좌출력포트(PL)에서 신호가 출력되지 않기 때문에 다이오드(D10)가 도통되지 않으므로 트랜지스터(Q9)가 오프되어 트랜지스터(Q10)가 오프되며 발광다이오드(LED10)는 소등된다. 이때 발광다이오드(LED1-LED4)의 점등상태는 상기의 설명과 같다.When tracking again to the right, the signal output from the right output port P R of the microcomputer 3 is applied to the base of the transistor Q 8 through the diode D 1 and is turned on so that the capacitor C 2 Since the charging voltage is discharged through the diode D 6 and the light emitting diodes LED 5 to LED 8 are turned off, no signal is output from the left output port P L of the microcomputer 3. Since the transistor 10 is not conducting, the transistor Q 9 is turned off so that the transistor Q 10 is turned off and the light emitting diode LED 10 is turned off. At this time, the lighting state of the light emitting diodes (LED 1- LED 4 ) is as described above.
그러므로 상기의 설명과 같이 점멸하는 발광다이오드(LED1-LED10)를 제2도의 (b)와 같이 브이씨알의 전면부 일측에 설치하면 사용자가 트래킹 할 때 트래킹 동작 및 상태를 쉽게 알 수 있다.Therefore, when the light emitting diodes (LED 1- LED 10 ) flashing as described above is installed on one side of the front part of V-Cal as shown in (b) of FIG. 2, the user can easily know the tracking operation and state when tracking.
이상의 상세한 설명에서와 같이 본 고안은 트래킹 동작 및 상태를 눈으로 확인 할 수 있으므로 리모콘으로 트래킹 할 때 편리하다는 이점이 있다.As described in the above detailed description, the present invention has a merit of being convenient when tracking with a remote controller since the tracking operation and status can be visually confirmed.
