본 고안은 비디오 테이프 레코더의 빨리감기나 되감기등의 테이프 주행시 소요되는 공백시간 동안 멜로디음을 들을 수 있도록한 멜로디 발생장치에 관한 것으로서 특히 빨리감기의 멜로디음과 되감기의 멜로디음을 구별하여 이용자로 하여금 멜로디음에 의해서도 어떠한 모드가 진행중인가를 판별할 수 있도록하는 비디오 테이프레코더의 멜로디 발생장치를 제공하려는 것이다.The present invention relates to a melody generating device that allows the user to hear the melody during the empty time required for tape driving such as fast-forwarding or rewinding a video tape recorder. It is an object of the present invention to provide a melody generating device of a video tape recorder capable of determining which mode is in progress by a melody sound.
종래의 비디오 테이프 레코더에 있어서는 되감기가 빨리 감기의 모드 수행시 각 모드가 선택되어지면서 시스콘 제어부(도시생략)에서 전달되어지는 신호에 의해 한 곡조의 멜로디음이 발생되어 짐으로서, 비데오 테이프 레코오더의 모드가 되감기 또는 빨리감기의 동작중인 것을 알 수 있게 한 것이나 때로는 이용자의 실수나 혹은 다른 일로인하여 원하지 않은 모드가 수행되어질때 이용자는 멜로디음만 듣고 정상적인 모드 수행중인 것으로, 오판하는 경우가 종종 발생 되어졌다.In a conventional video tape recorder, when a mode of rewinding is fast-forwarded, each mode is selected and a melody sound of one tune is generated by a signal transmitted from a scissor control unit (not shown). When the mode of rewinding or fast forwarding is activated, or sometimes an unwanted mode is performed due to a user's mistake or other work, the user hears only the melody sound and is in the normal mode. It was done.
따라서 본 고안은 비데오 테이프 레코오더의 빨리감기나 또는 되감기 모드 수행시 발생되어지는 멜로디음을 각기 구분 함으로서 이용자가 그 모드 선택시 발생되는 멜로디 음에 의해서 정상모드 선택중인 것을 판별할수 있도록 하는 장치를 제공하는데 목적이 있는 것이다.Therefore, the present invention provides a device for distinguishing the normal mode by the melody sound generated when selecting the mode by distinguishing the melody sound generated when the video tape recorder is fast-forwarded or rewinded. The purpose is to.
상기 목적을 달성시킬 수 있는 본 고안의 구성을 첨부된 도면에 의하여 설명하면 다음과 같다.Referring to the accompanying drawings the configuration of the present invention that can achieve the above object is as follows.
TV/VTR 단자(TV/VTR)에 에이터 접지된 트랜지스터(Q1)의 에이스를 연결하고 그 콜렉터에 저항(R1)을 통한 공급전원(Vcc)을 연결하되 그 단에 베이스에 재생단자(PLAY)가 접속된 트랜지스터(Q2)의 콜렉터를 접속하여서 그 에미터는 병렬연결되는 저항(R2, R3)을 통해 트랜지스터(Q1, Q4)와 멜로디부(M1, M2) 및 피에조(P1, P2) 되감기 단자(REW)와 빨리감기 단자(FF)를 연결하여 구성한다.TV / VTR terminal (TV / VTR) Actuator connecting one of the grounding transistor (Q 1) to and but connected to the power supply (Vcc) via a resistor (R 1) to the collector reproduction terminal to the base to the end (PLAY ) Is connected to the collector of the transistor (Q 2 ) connected to the emitter through the resistors (R 2 , R 3 ) connected in parallel to the transistors (Q 1 , Q 4 ) and melody parts (M 1 , M 2 ) and piezo (P 1 , P 2 ) It is composed by connecting the rewind terminal (REW) and the fast rewind terminal (FF).
이와같이 구성된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention configured as described above are as follows.
먼저 이용자가 VTR을 보기 위해 비디오 태이프 레코더의 기능중에서 TV/VTR단자 (TV/VTR)중 VTR을선택하였을 경우에는 도시되지 않은 시스콘 제어부로부터 로우신호가 TV/VTR단자 (TV/VTR)에 입력이 되어 트랜지스터(Q1)은 턴 오프 된다.First, when the user selects the VTR among the TV / VTR terminals (TV / VTR) among the functions of the video tape recorder to view the VTR, a low signal is inputted to the TV / VTR terminal (TV / VTR) from a system controller not shown. The transistor Q 1 is thus turned off.
이와 같은 상태에서 VTR의 모든 데크 매카니즘의 기능수행(예 : 테이프장착)이 완료되어진 이후 재생버튼(도시생략)을 누르게 되면 시스콘 제어부는 재생단자(PLAY)에 로우신호를 인가시킨다.In such a state, when the play button (not shown) is pressed after the performance of all deck mechanisms of the VTR (eg, tape mounting) is completed, the sheath control unit applies a low signal to the play terminal PLAY.
따라서 트랜지스터(Q2)가 턴 오프됨으로써 재생모드시에는 멜로디음이 발생되지 않고 정상적인 동작을 하게된다.Accordingly, since the transistor Q 2 is turned off, the melody sound is not generated in the regeneration mode and normal operation is performed.
반면에 VTR의 재생모드가 작동되지 않는 경우에는 재생단자(PLAY)에 하이 신호가 인가되어 트랜지스터(Q2)가 턴온된다. 이런 상태에서 이용자가 버튼 스위치를 누르게될 경우에는 VTR의 데크 메카니즘은 되감기 모드가 수행이 됨과 동시에 그 되감기단자(REW)에는 시스콘 제어부로부터 로우 신호가 입력되어 트랜지스터(Q3)는 턴오프 된다.On the other hand, when the regeneration mode of the VTR is not activated, a high signal is applied to the regeneration terminal PLAY, thereby turning on the transistor Q2. In this state, when the user presses the button switch, the deck mechanism of the VTR performs the rewind mode and at the same time, a low signal is input to the rewind terminal REW and the transistor Q 3 is turned off.
이에 저항(R2)을 통한 공급전원(Vcc)이 멜로디부(M1)에 입력되어 동작을 하게되고 그 특성의 지정된 멜로디 신호가 피에조(P1)에 전달되어져 소정의 멜로디음이 발생하게 된다.The power supply Vcc through the resistor R 2 is input to the melody unit M 1 to operate, and a specified melody signal of the characteristic is transmitted to the piezo P 1 to generate a predetermined melody sound. .
또한 빨리감기 모드가 선택될시에도 상기와 마찬가지로 멜로디부(M2)가 동작하여 그 특유의 멜로디음이 피에조(P2)를 통해 발생하게 되는 것이다.In addition, when the fast-forward mode is selected, the melody part M 2 operates in the same manner as described above, and a unique melody sound is generated through the piezo P 2 .
단 여기에서 시스콘 제어부는 빨리감기 모드나 되감기 모드가 선택되어 지는 것에 관계없이 한 모드가 선택되면 선택어진 모드의 신호단자에는 로우신호가 입력됨과 동시에 다른 한 모드에는 자동적으로 하이 신호가 입력이 된다. 따라서, 두 멜로디부(M1, M2)가 동시에 작동하는 경우는 없는 것이다.Here, if the mode is selected, regardless of whether fast forward mode or rewind mode is selected, a low signal is input to the signal terminal of the selected mode and a high signal is automatically input to the other mode. . Therefore, no two melody parts M 1 and M 2 operate simultaneously.
이상에서와 같이 본 고안은 빨리감기와 되감기 모드에 각기 다른 멜로디부를 구성시킴으로써 TV/VTR에서 VTR모드가 선택되어진 상태일 경우에 빨리감기나 되감기 모드중 한 모드가 선택이 되이지면 그 선택된 모드 고유의 멜로디음을 말하게 함으로씨 이용자가 그 멜로디음에 의해 원하는 모드가 수행중임을 판단할 수 있으므로 기존 VTR의 기능을 한층더 높여수는 효과가 있는 것이다.As described above, the present invention configures different melody parts in the fast-forward and rewind modes so that when one of the fast-forward or rewind modes is selected when the VTR mode is selected in the TV / VTR, By letting the melody sound, the user can determine that the desired mode is being performed by the melody sound, which has the effect of further enhancing the function of the existing VTR.
