본 고안은 전자기기에서 전압의 레벨이나 가변저항의 변화상태를 지시계용 LED에 표시하는 회로에 있어서 그 구성적 간단함과 가변적 용도를 부여하도록 한 모드셀렉터에 관한 것이다.The present invention relates to a mode selector which provides a simple configuration and a variable use in a circuit for displaying a voltage level or a change state of a variable resistor in an LED for an electronic device.
현재까지 알려진 제4도와 같은 종래의 모드 셀렉터에 있어서는 가변저항의변화에 따라 저항값이 변하고 이 상태에서의 임의의 출력단자 중 비교값에 이상되는 상태에서 1개의 비교기가 출력을 발하여 모드 동작신호를 얻도록 하고 있다, 여기서 배타오어게이트와 전압비교기 및 기준전압 설정용 저항 접속부의 3부분으로 나누어지며 이러한 회로에서 얻어지는 모드는 일정간격 또는 임의간격 계단식 출력변화를 나타내고 있었다.In the conventional mode selector as shown in FIG. 4, the comparator outputs a mode operation signal when the resistance value changes according to the change of the variable resistor and the output value exceeds the comparison value among any output terminals in this state. Here, it is divided into three parts, the exclusive or gate, the voltage comparator and the resistor connection part for setting the reference voltage. The mode obtained in such a circuit shows a stepped output change at a constant interval or at an arbitrary interval.
그러나 이러한 종래의 것에 있어서는 논리회로부는 배타논리구성으로써 다수의 직접된 IC 부품 또는 개별부품이 사용돼야 하고, 또 계단식 전압 검출 레벨에 의하여 선형적인 상태의 가변변화를 특정하게 얻기 어려운 모드로 된다는 결점이 있었다.However, in this conventional case, the logic circuit portion has an exclusive logic structure, in which a large number of direct IC components or individual components have to be used, and a step in which the variation of the linear state is difficult to be specifically obtained due to the stepped voltage detection level is a disadvantage. there was.
즉, VTR의 경우는 특정모드사이, 즉 정지(STILE)와 저속재생() 사이에 변속기능에 대한 가변저항을 동일측의 저항으로 구성해야 할 필요가 있으나, 이러한 모드에 적용하기 어려웠던 것이었다.That is, in the case of the VTR, between specific modes, that is, stop (STILE) and slow playback ( It was necessary to configure the variable resistance for the shift function with the same resistance, but it was difficult to apply to this mode.
본 고안은 종래의 이러한 불편에 착안하여 안출한 것인데, 이는 입력부의 가변저항을 사용코자 할 때 임의 간격에서 별도의 모드 선택신호를 출력케 하는 회로 구성과 각각의 간격마다 모드 선택 출력용 비교기 접속을 새롭게 하므로써 구성적 간단함과 임의의 선택신호한개를 선정하여 선형적 가변모드를 얻을 수 있도록 한 목적이 있는 것이다.The present invention has been devised in view of the above-mentioned inconveniences, which is a circuit configuration for outputting a separate mode selection signal at random intervals when a variable resistor of the input unit is used, and a comparator connection for mode selection output at each interval is newly renewed. Therefore, the purpose of the present invention is to provide a linear variable mode by selecting a simple structure and an arbitrary selection signal.
이하에서 이를 상세히 설명하면 다음과 같다.This will be described in detail below.
입력전원의 가변을 위한 가변저항(R1)과 저항(Ra)을 거쳐 병렬로 n개의기준전압 설정용 저항(Rb, R10, R11, RF, RG, RH, R13……Ry, Rx)을 직렬로 하여 접속하고, 이를 n개의 비교기(OP1-OPn) 일단에 각기 접속한다.N sets of reference voltages in parallel (R b , R 10 , R 11 , R F , R G , R H , R 13 ) in parallel through a variable resistor (R 1 ) and a resistor (R a ) for varying the input power; connected to the ...... R y, R x) in series, and each of them connected to one end n of the comparator (OP 1 -OP n).
상기 n개의비교기(OP1-OPn) 일단에 접속된 저항(Rb, R10, R11-Rx) 사이의 소정단위 비교기(OP3, OP4) 사이의 레벨검출 (1)의 저항(RF, RG, RH) 사이에서 인출한 라인에 비교기(OPa, OPb)일단을 접속하고, 이 비교기(OPa, OPb)타단은 다이오드(Da)를 거쳐 가변저항(Rb)과 저항(Ra) 사이에 접속하고, 상기 비교기(OPa, OPb)출력은 낸드게이트(G)를 거쳐 트랜지스터(Qb) 베이스단 및 모드신호출력단(As)과 접속하며, 상기 트랜지스터(Qb) 컬렉터단은 가변저항(R1) 및 저항(Ra) 사이의 라인을 한 입력으로 한 증폭기(OPc)의출력(AR)을 제어하는구성이다.Resistance of level detection 1 between predetermined unit comparators OP 3 and OP 4 between resistors R b , R 10 and R 11 -R x connected to one end of the n comparators OP 1 -OP n . One end of the comparator (OP a , OP b ) is connected to the line drawn between (RF, RG, RH), and the other end of the comparator (OP a , OP b ) passes through the diode (D a ) and the variable resistor (R b ). And a resistor (R a ), the comparator (OP a , OP b ) output is connected to the transistor (Q b ) base terminal and the mode signal output terminal (A s ) through the NAND gate (G), the transistor (Q b) a collector stage is configured to control the output (AR) of the amplifier (OP c) as input to a line between the variable resistor (R 1) and a resistor (R a).
또 상기 비교기(OP1-OPn)의 또 다른 입력인 비반전단자(+)엔 n개의 다이오드(D1-Dn)를 순차 접속하여 저항(Ra)과 가변저항(R1) 사이에 접속하고, 상기 비교기(OP1-OPn) 출력은 n개의 스위칭용 트랜지스터(T1-T4) 입력단과 모드신호 LED출력(A1-An)으로 연결되며, 상기 트랜지스터(T1-T4)의 출력단은 n개의 다이오드(D1-Dn) 각 사이에 접속시켜서 이 다이오드(D1-Dn)의 애노드에 바이어스 저항(Rz1-Rzn)을 연결하여 전원단자(B+)에 접속시킨다. 그리고 상기 증폭기(OPc)의 입력단은 가변저항(R1) 또는 독단의 가변저항(R1)과 연동되는 독단의 가변저항(R0)으로 접속한 구성이다.Further, n diodes D 1 -D n are sequentially connected to the non-inverting terminal (+), which is another input of the comparator (OP 1 -OP n ), between the resistor R a and the variable resistor R 1 . The comparator (OP 1 -OP n ) output is connected to n switching transistors (T 1 -T 4 ) input terminal and the mode signal LED output (A 1 -A n ), the transistor (T 1 -T) the output terminal of the 4) n diodes (D 1 -D n) by the connection between each diode (D 1 -D n), a bias resistor (Rz 1 -Rz n) connected to a power supply terminal (B + a) to the anode of the To. And an input terminal of said amplifier (OP c) consists of connecting a variable resistor (R 0) of the dogma that works with a variable resistor (R 1) or a variable resistance (R 1) of the arbitrariness.
또 제3도는 본 고안에 따른 가변저항기(R1)를 모드 선택별로 구분하고 선형변화부분을 예시하고 있다. 이러한 구성의 본 고안은 전원(B+)으로부터 각 저항(R1-Rx)에 전원이 공급되고 이에 따라 비교기OP1-OPn) 일단에 각기 다른 기준전압차가 설정된다.3 illustrates the variable resistor R 1 according to the present invention for each mode selection and illustrates a linear change portion. According to the present invention of this configuration, power is supplied from the power supply B + to each of the resistors R 1 -R x so that different reference voltage differences are set at one ends of the comparators OP 1 -OP n ).
또 바이어스 저항(Rz1-Rzn)과 다이오드(D1-Dn)와 트랜지스터(T1-T4) 및 비교기(OP1-OPn)로써 모드 판별회로측단 수단으로 하고 있으므로 가변저항(R1)의 가변전압치로 모드 신호 LED 출력단(A1-An)에 해당 출력이 나타난다.Since the bias resistors Rz 1 -Rz n , the diodes D 1 -D n , the transistors T 1 -T 4 , and the comparators OP 1 -OP n are used as the mode discrimination circuit measuring means, the variable resistor R 1 ) The output is displayed at the mode signal LED output terminal (A 1 -A n ) with the variable voltage value.
즉 비교기(OP1-OPn) 출력은 비교입력전압치와 기준치와의 차로써 그 출력이 발생하므로 비교치가 정(+)이면 논리 H, 비교치가 부(-)이면 논리 L로써 논리 H시에는 차단트랜지스터(Tn-1)가 동작하여 차단비교기(OPn-1)의 입력을 차단하므로 무조건 1개의 출력이 나타난다(이는 제2도의 계단파형이다).That is, since the output of the comparator (OP 1 -OP n ) is the difference between the comparison input voltage value and the reference value, the output is logical H when the comparison value is positive, and logic L when the comparison value is negative. Since the cutoff transistor T n-1 operates to cut off the input of the cutoff comparator OP n-1 , one output is unconditionally displayed (this is a stepped waveform in FIG. 2).
또 소정모드신호 LED출력단(A3, A4)은 가변저항의 선형적인 변화를 얻고자 하는 부분이어서 기준저항(RF, RG, RH)에 의한 전압변화상태에 따라 출력이 결정되고, 이는 비교기(OPa, OPb)와 낸드 게이트(G)로 레벨검출기(1)가 되어 상기 기준저항(RF, RG, RH) 중 저항(RG)에 해당하는 간격의 전압변화 범위에서 이의 출력이 발생되며, 이 출력이 모드신호출력단(As)에 가해진다. 그러므로 평상시 모드에서는 레벨검출기(1)의 게이트(G)출력이 논리 H로써 트랜지스터(Qb)가 언(ON)된 상태로서 가변저항(R1, R0)로 설정된 전압이 증폭기(OPc)로 가해지고 이 증폭기(OPc)의 출력을 차단하고 있으므로 평상시 계단적 모드가 되는 것이나, 상기 낸드 게이트(G) 출력논리가 L로 되므로써 트랜지스터는(Qb)는 오프되어 가변저항(R1, R0)에 의한 수조한 선형변화를 출력하게 되는 것이다.In addition, the predetermined mode signal LED output stages A 3 and A 4 are to obtain a linear change of the variable resistor, so the output is determined according to the voltage change state by the reference resistors RF, RG, and RH. OP a , OP b ) and the NAND gate G become the level detector 1, and its output is generated in the voltage change range of the interval corresponding to the resistance RG among the reference resistors RF, RG, and RH. this output is applied to the mode signal output (a s). Therefore, in the normal mode, the voltage set by the variable resistance (R 1, R 0) as the gate (G) the output of the level detector (1) as a logical H transistor (Q b) is frozen (ON) state amplifier (OP c) since the is applied to block the output of the amplifier (OP c) would be the normal staircase ever mode, the NAND gate (G) output logic doemeurosseo transistor L is (Q b) it is off the variable resistance (R 1, R 0 ) outputs a trillion of linear changes.
즉 이는 제2도의 계단파 중 선형부분으로 나타난다. 이 때는 가변저항(R1)이 VTR에 적용될 때 제3도와 같이 가변저항기(R1)로 구성되어 일반적인 모드 일예로 CUE(X15), CUE(X9), CUE(X5), FAST(X3), FAST(X2), REVERSE(X1), REVIEW(X5), REVIEW(X9) 외에 저속인 SLOW(X)에서 정지인 still(1/32) 모드까지는 슬라이드 형태의 선형변화가 이루어지는 것이다. 또 상기 가변저항(R1)은 본 고안에 예시된 바와 같이 별도의 선형변화용 가변저항(R0)을 증폭기(OPc) 입력단에 두어 독립적으로 운영할 수도 있는 것이다.That is, it appears as a linear part of the step wave of FIG. In this case, when the variable resistor R 1 is applied to the VTR, it is composed of the variable resistor R 1 as shown in FIG. 3. As a general mode, CUE (X15), CUE (X9), CUE (X5), FAST (X3), In addition to FAST (X2), REVERSE (X1), REVIEW (X5), REVIEW (X9), low-speed SLOW (X ), The linear change in the form of a slide occurs from still (1/32) mode to stop. In addition, the variable resistor (R 1 ) may be independently operated by putting a separate linear variable variable resistor (R 0 ) at the input terminal of the amplifier (OP c ) as illustrated in the present invention.
이러한 본 고안은 VTR 등의 모드셀렉터에 있어서 이를 비교적 간단한 단일소자에 의한 구성으로 하여 제작상의 용이함이 있으며, 특히 필요부위에 선형적인 변화모드를 설정할 수 있어 그 활용성이 매우 증대되며, 그 이용가치를 현저히 상승시킨 유익한 특징이 있는 것이다.The present invention is easy to manufacture by using a relatively simple single element in a mode selector such as a VTR, and in particular, the linear change mode can be set at a required part, and its usefulness is greatly increased. There is a beneficial feature that significantly increased.
