본 발명은 브이씨알 구동중 테이프의 잔량을 사용자가 쉽게 인지할 수 있도록 한 테이프 잔량 표시장치에 관한 것으로, 특히 녹화중 유용하게 활용할 수 있게 한 테이프 잔량 표시방법 및 장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a tape remaining amount display device that enables a user to easily recognize the remaining amount of tape during V-real driving, and more particularly, to a method and apparatus for displaying a remaining amount of tape which can be usefully used during recording.

종래 탑로딩(Top-Loading) 방식의 브이씨알에서는 테이프 잔량이 어느정도인지를 육안으로 대강 알 수 있었으나, 근래의 프론트로딩(Front-Loading) 방식의 브이씨알에서는 테이프를 볼 수 없기 때문에 테이프 잔량 정도를 알 수 없었다.In the conventional top-loading method, the amount of tape remaining can be roughly determined by the naked eye. However, in the case of the front-loading method, the amount of tape remaining is not available. I didn't know.

따라서 사용하던 테이프로 녹화할 때, 특히 예약녹화 할 때 녹화하려는 프로그램시간에 대해 테이프 잔량이 충분한지를 알수 없어 불편함이 많았다.Therefore, it was inconvenient to know whether the remaining tape was enough for the program time to be recorded, especially when recording with the used tape.

또한, 최근에는 테이프의 잔량에 따라 달라지는 공급릴의 회전주기를 감지한 후 파형 정형회로, 미분기, 분주기, 카운터 및 디지탈/아날로그 변환기를 순차로 통해 샘플링/홀드하고, 그 신호값에 따라 제어마이컴에서 테이프 잔량시간을 계산한 후 그 잔량시간을 표시하여 주는 기술이 알려졌으나, 이는 그의 구성이 복잡할 뿐 아니라 그 처리 과정이 복잡하고, 테이프의 잔량을 시간으로 표시하여 주므로 시각적인 효과가 떨어지는 문제점이 있었다.In addition, recently, after detecting the rotation cycle of the supply reel, which is dependent on the remaining amount of tape, the waveform shaping circuit, the differentiator, the divider, the counter, and the digital / analog converter are sequentially sampled and held. The technique of displaying the remaining time after calculating the remaining tape time has been known, but it is not only complicated in its composition, but also complicated in the processing process, and shows the remaining amount of tape in time, thereby reducing the visual effect. There was this.

본 발명은 이러한 종래의 문제점을 감안하여, 공급릴 펄스수 및 권취릴 펄스수의 차이로부터 테이프의 잔량을 검출하고, 그 테이프 잔량 검출신호에 따라 발광다이오드를 순차 누적 점등시켜 시각적 효과를 향상시키게 창안한 것으로, 이를 첨부된 도면을 참조하여 상세히 설명하면 다음과 같다.In view of such a conventional problem, the present invention detects the remaining amount of tape from the difference between the number of supply reel pulses and the number of winding reel pulses, and sequentially accumulates and emits light-emitting diodes in accordance with the remaining signal detection signal to improve visual effects. If it is described in detail with reference to the accompanying drawings as follows.

브이씨알의 권취릴 및 공급릴에 제3a도에 도시한 바와 같은 릴센서를 설치하면, 릴플레이트(1)가 회전함에 따라 발광다이오드(LED10)의 빛은 릴플레이트(1)에 의해 반사 및 투과되어 포토트랜지스터(PT1)가 온, 오프되므로 각각의 릴센서에서 릴펄스가 발생한다.When the reel sensor as shown in FIG. 3a is installed on the winding reel and supply reel of V-CAL, the light of the light emitting diode LED 10 is reflected and transmitted by the reel plate 1 as the reel plate 1 rotates. As the phototransistor PT1 is turned on and off, reel pulses are generated at each reel sensor.

이와 같이 발생하는 권취릴펄스 및 공급릴펄스를 소정시간동안 계수한 값을 각각 권취릴펄스수(B), 공급릴펄스수(A)라 할 때, 테이프의 주행속도는 일정하기 때문에 권취릴 및 공급릴에 감겨있는 테이프의 양이 달라지면 권취릴펄스수(B) 및 공급릴펄스수(A)의 값이 변하게 된다.When the winding reel pulses and the supply reel pulses generated in this manner are counted for the predetermined time, the winding reel pulse number (B) and the supply reel pulse number (A), respectively, the running speed of the tape is constant. When the amount of tape wound on the supply reel is changed, the value of the winding reel pulse number (B) and the supply reel pulse number (A) is changed.

따라서 공급릴에 감겨있는 테이프의 양, 즉 테이프의 잔량에 따라 공급릴펄스수와 권취릴펄스수의 차(A-B)가 달라지므로 A-B의 값을 일정간격으로 8등분하여, 그 각각을 테이프 잔량 설정값

이를 참조하여 본 발명의 표시방법 및 표시장치를 살펴보면 아래와 같다.Looking at the display method and the display device of the present invention with reference to this.

제1도 및 제2도는 각각 본 발명의 표시방법 흐름도 및 표시장치 회로도로서, 이에 도시한 바와같이 브이씨알의 구동시 테이프 잔량 표시장치를 구동시키기 위해 제4도에 도시한 것과 같은 표시장치 스위치를 테이프의 종류에 따라 온시키면, 그 테이프종류에 따라 테이프 잔량 설정값(

Figure kpo00005
)이 얽혀져 소정시간동안의 공급릴펄스수(A)와 권취릴펄스수(B)의 차, 즉 A-B가 어느 테이프 잔량 설정값(
Figure kpo00006
)에 해당되는지 판단된 뒤 테이프 잔량 설정값(
Figure kpo00007
)의 K에 대한 2진데이타(xyz)2가 마이콤의 각 비트신호 출력단자(X), (Y), (Z)로부터 출력된다.1 and 2 show a display method flow diagram and a display device circuit diagram of the present invention, respectively. As shown in FIG. 1, a display device switch as shown in FIG. If it is turned on according to the type of tape, the remaining tape setting value (
Figure kpo00005
) Is intertwined so that the difference between the supply reel pulse number A and the reel reel pulse number B during a predetermined time, i.
Figure kpo00006
), Then the remaining tape setting value (
Figure kpo00007
Binary data (xyz) 2 for K of) is output from the respective bit signal output terminals X, Y, and Z of the microcomputer.

또, 테이프 잔량을 시각적으로 알 수 있게 제2도에 도시한 것과 같은 표시장치를 구성한다. 즉 출력단자(X)의 비트(x) 신호는 오아게이트(OR1-OR3) 및 앤드게이트(AND2-AND4)의 입력단자에, 출력단자(Y)의 비트(y)신호는 오아게이트(OR1, OR2, OR4) 및 앤드게이트(AND1, AND3, AND4)의 입력단자에 출력단자(Z)의 비트(z)신호는 오아게이트(OR11, OR4) 및 앤드게이트(AND1, AND4)의 입력단자에 각기 인가되게 접속함과 아울러 상기 앤드게이트(AND1)의 출력신호 및 오아게이트(OR4)의 출력신호가 상기 오아게이트(OR3) 및 앤드게이트(AND2)의 입력단자에 각각 인가되게 접속하여, 상기 오아게이트(OR1),(OR2),(OR3)의 출력단자측에 발광다이오드(LED1),(LED2),(LED3)를 각기 접속하고, 출력단자(X)에 발광다이오드(LED4)를 접속하여, 상기 앤드게이트(AND2),(AND3),(AND4)의 출력단자측에 발광다이오드(LED5), (LED6), (LED7)를 각각 접속하여 구성한다.In addition, the display device as shown in FIG. 2 is constituted so that the remaining tape amount is visually known. That is, the bit (x) signal of the output terminal (X) is the input terminal of the OR gate (OR 1- OR 3 ) and the AND gate (AND 2 -AND 4 ), the bit (y) signal of the output terminal (Y) is The bit (z) signal of the output terminal (Z) at the input terminals of the gates (OR 1 , OR 2 , OR 4 ) and the AND gates (AND 1 , AND 3 , AND 4 ) is the oragate (OR1 1 , OR 4 ) and the aND gate (aND 1, aND 4) and also each is to be connected to the input terminal as well as the output signal of the output signal and Iowa gate (OR 4) of the aND gate (aND 1) the Iowa gate of the (OR 3) and end Connected to the input terminals of the gate AND 2 , respectively, and connected to the output terminals of the OR gates OR 1 , OR 2 , and OR 3 , the light emitting diodes LED 1 , LED 2 , and ( LED 3 ) are connected to each other, and the light emitting diode LED 4 is connected to the output terminal X, and the light emitting diode LED is connected to the output terminals of the AND gates AND 2 , AND 3 , and 4 . 5 ), (LED 6 ), and (LED 7 ) are connected respectively.

따라서 테이프 잔량이 최대일 때 발광다이오드 (LED1-LED7)는 모두 소등되고, 최소일 때 발광다이오드 (LED1-LED7)가 모두 점등된다. 예를 들면, 소정시간동안의 공급릴펄스수가 권취릴펄스수의 차, A-B가 T3일 때 K=3이므로 (xyz)2=(Φ11)2이다. 이때 오아게이트(OR1-OR3)의 출력단자로만 고전위신호가 출력되어 발광다이오드(LED1-LED3)가 점등된다. 또 A-B=T6일 때 K=6이므로 (xyz)2=(11Φ)2이다. 따라서 발광다이오드(LED1-LED6)에 고전위신호가 인가되어 그들이 점등된다.Therefore, when the tape remaining amount up to the light emitting diode (LED 1 -LED 7) are both turned off, and is turned on when all of the at least one light emitting diode (LED 1 -LED 7). For example, K = 3 when the supply reel pulse number for a predetermined time is different from the winding reel pulse number, AB is T3, so that (xyz) 2 = (Φ 11) 2 . At this time, the high potential signal is output only to the output terminals of the OR gates (OR 1- OR 3 ) so that the light emitting diodes (LED 1- LED 3 ) are turned on. In addition, when AB = T 6 , K = 6, so (xyz) 2 = (11Φ) 2 . Therefore, a high potential signal is applied to the light emitting diodes LED1-LED6 and they are turned on.

이와 같은 표시장치에 있어서, 제3b도와 같은 종래의 릴플레이트를 제3c도와 같은 릴플레이트로 교체하면 릴플레이트의 1회전에 대한 릴펄스수가 증가되므로 소정시간동안의 공급릴펄스수와 권취릴펄스수의 차, A-B가 정확해져 표시장치가 보다 더 정확하게 동작한다.In such a display device, when the conventional reel plate as shown in Fig. 3b is replaced with the reel plate as shown in Fig. 3c, the number of reel pulses for one revolution of the reel plate is increased, so that the number of reel pulses and the number of winding reel pulses for a predetermined time period are increased. , The AB becomes accurate, and the display device operates more accurately.

이상에서 상세히 설명한 바와 같이 본 발명은 녹화시 시간배분이 용이하고, 특히 예약녹화시에 방송프로그램을 모두 녹화할 수 있으며, 2개의 릴센서로 일정주기 릴카운트하여 테이프 잔량 범위를 정확히 검출할 수 있으며, 그 테이프 잔량을 발광다이오드의 순차 누적 점등으로 표시하게 되므로 시각효과가 향상되는 효과가 있게 된다.As described in detail above, the present invention facilitates time distribution during recording, and in particular, can record all broadcast programs during scheduled recording, and can accurately detect the remaining amount of tape by reeling a predetermined period with two reel sensors. In addition, since the remaining tape amount is displayed as the sequential cumulative lighting of the light emitting diode, the visual effect is improved.
