There was a flaw in boredom during certain modes.

본 고안은 이러한 종래의 결점을 감안하여, 테이프를 넣거나 뺄때, 또는 빨리보내기, 되감기, 무녹화 부분에서의 재생등과 같은 특정모드에서는 멜로디를 발생시킬 수 있게 안출한 것으로, 이를 첨부된 도면에 참조하여 상세히 설명하면 다음과 같다.The present invention has been made in view of the above-mentioned drawbacks, and it is possible to produce a melody in a specific mode such as when inserting or removing a tape, or fast forwarding, rewinding, or playing back in a non-recorded part. When described in detail as follows.

첨부된 도면은 본 고안의 모드별 멜로디 발생장치 회로도로서 이에 도시한 바와같이, 재생영상신호단자(VS)를 동기 검출부(1)의 압력측에 접속하여 그의 출력측을 트랜지스터(Ql)의 베이스에 접속하고, 플레이신호단자(PS)를 저항(R5)을 통해 트랜지스터(Q2)의 베이스에 접속함과 아울러 저항(R6)을 통해 트랜지스터(Q3)의 콜렉터에 접속하며, 캡스턴드라이브신호단자(CS)를 저항(R8)을 통해 상기 트랜지스터(Q3)의 베이스에 접속하며, 레코드신호단자(RS) 및 뮤트신호단자(MS)를 다이오드(D4), (D5)를 각각 통한 후 저항(R9)을 다시통해 트랜지스터(Q4)의 베이스에 접속하여, 상기 트랜지스터(Q1),(Q2)의 콜렉터는 다이오드(Dl)를 통하고, 상기 트랜지스터(Q3)의 콜렉터는 다이오드(D2)를 통하여, 로딩신호단자(LS)는 저항(R7) 및 다이오드(D3)를 통해 상기 트랜지스터(Q4)의 콜렉터에 공통접속하고, 이 접속점을 스위치(SW1) 및 저항(Rl0)을 통해 트랜지스터(Q5)의 베이스에 접속하여 그의 콜렉터를 저항(R14)을 통해 트랜지스터(Q6)의 베이스에 접속하고, 이 트랜지스터(Q6)의 에미터를 전원단자(Vcc)에 접속함과 아울러 그의 콜렉터를 멜로디집적소자(2)의 전원단자에 접속하여 구성한 것으로, 상기 플레이신호단자(PS)에는 빨리보내기 및 되감기시에 고전위 신호가 인가되게 되어 있고, 로딩신호단자(LS)에는 테이프를 넣거나 뺄때 고전위 신호가 인가되게 되어있고, 캡스턴드라이브신호단자(CS)에는 빨리보내기 및 되감기 완료시에 고전의 신호가 인가되게 되어있으며, 레코드신호단자(RS)및 뮤트신호단자(MS)는 레코드 및 뮤트시에 각각 고전위 신호가 인가되게 되어있다.The accompanying drawings show a mode-specific melody generating device circuit diagram of the present invention, and as shown therein, the playback video signal terminal VS is connected to the pressure side of the synchronization detecting unit 1 and its output side is connected to the base of the transistor Q l . Connects the play signal terminal PS to the base of the transistor Q 2 through the resistor R 5 , and to the collector of the transistor Q 3 through the resistor R 6 , the capstan drive signal The terminal CS is connected to the base of the transistor Q 3 through a resistor R 8 , and the record signal terminal RS and the mute signal terminal MS are connected to the diodes D 4 and D 5 , respectively. After passing through, the resistor R 9 is again connected to the base of the transistor Q 4 , so that the collectors of the transistors Q 1 and Q 2 pass through the diode D 1 and the transistor Q 3 . the collector via a diode (D 2), the loading signal terminal (LS) via a resistor (R 7) and a diode (D 3) Commonly connected to a collector of the group transistor (Q 4), and connected to the base of the junction switch (SW 1) and a resistor (R l0) transistor (Q 5) through the transistor to its collector via a resistor (R 14) It is configured by connecting to the base of (Q 6 ), connecting the emitter of this transistor (Q 6 ) to the power supply terminal (Vcc), and connecting the collector thereof to the power supply terminal of the melody integrated device (2). A high potential signal is applied to the signal terminal PS at the time of fast forwarding and rewinding, and a high potential signal is applied to the loading signal terminal LS when the tape is inserted or removed, and quickly to the capstan drive signal terminal CS. The high signal is applied at the completion of the sending and rewinding, and the high potential signal is applied to the record signal terminal RS and the mute signal terminal MS at the time of recording and muting, respectively.

이와같이 구성된 본 고안의 작용효과를 상세히 설명하면 다음과 같다.Referring to the effects of the present invention configured in this way in detail as follows.

재생영상신호단자(VS)에 재생영상신호가 입력되면, 이 재생영상신호는 동기검출부(1)에 인가되므로 그 동기검출부(1)에서 동기신호가 검출되어 그의 출력측에 고전위신호가 출력되고, 이 고전위 신호는 트랜지스터(Q1)를 온시키므로 그의 콜렉터에 저전위 신호가 출력된다. 마라서, 이때 트랜지스터(Q5), (Q6)는 오프상태를 유지하여 멜로디집적소자(2)에 전원이 공급되지 않으므로 그 멜로디집적소자(2)는 구동되지 않게된다.When a reproduced video signal is inputted to the reproduced video signal terminal VS, the reproduced video signal is applied to the synchronization detecting section 1, so that the synchronization signal is detected at the synchronization detecting section 1, and a high potential signal is output to the output side thereof. This high potential signal turns on the transistor Q 1 so that a low potential signal is output to its collector. Therefore, at this time, the transistors Q 5 and Q 6 remain off so that the melody integrated element 2 is not supplied with power, so that the melody integrated element 2 is not driven.

그러나, 테이프의 무녹화 부분 재생시에는 재생영상신호단자(VS)에 재생영상신호가 입력되지 않으므로 동기검출부(1)에서 동기신호가 검출되지 않아 그의 출력측에 저전위 신호가 출력되고, 이 저전위 신호는 트랜지스터(Ql)를 오프시키게 된다. 따라서, 이때 전원단자(Vcc)의 전원이 저항(R2) 및 다이오드(D1), 스위치(SWl), 저항(R10)을 통해 트랜지스터(Q5)를 온시키므로 트랜지스터(Q6)도 온되어 그의 콜렉터에 고전위 신호가 출력되고, 이 고전위 신호는 멜로디집적소자(2)의 전원단자에 인가되므로 그 멜로디집적소자(2)가 구동되어 멜로디음이 출력된다.However, during playback of the non-recorded portion of the tape, since the playback video signal is not input to the playback video signal terminal VS, no synchronization signal is detected by the synchronization detection unit 1, and a low potential signal is output to the output side thereof. Turns off the transistor Q l . Accordingly, at this time, the power supply of the power supply terminal Vcc turns on the transistor Q 5 through the resistor R 2 , the diode D 1 , the switch SW l , and the resistor R 10 , so that the transistor Q 6 is also used. It turns on and outputs a high potential signal to its collector, and this high potential signal is applied to the power supply terminal of the melody integrated element 2 so that the melody integrated element 2 is driven to output a melody sound.

또한, 테이프 카세트를 넣거나 빼는 경우에는 로딩신호단자(LS)에 고전위 신호가 인가되므로 이 고전위신호는 저항(R7) 및 다이오드(D3), 스위치(SW1), 저항(R10)을 통해 트랜지스터(Q5), (Q6)를 온시키게 된다. 따라서, 이때트 멜로디집적소자(2)가 구동되어 멜로디음이 출력된다. 이후 테이프 카세트를 넣거나 빼는 동작이 완료되면 로딩신호단자(LS)에 저전위 신호가 인가되므로 트랜지스터(Q5), (Q6)는 오프되어 멜로디집적소자(2)의 구동이 중지된다.In addition, since the high potential signal is applied to the loading signal terminal LS when the tape cassette is inserted or removed, the high potential signal is a resistor (R 7 ), a diode (D 3 ), a switch (SW 1 ), and a resistor (R 10 ). The transistors Q 5 and Q 6 are turned on. Therefore, at this time, the melody integrated device 2 is driven to output a melody sound. Since the low potential signal is applied to the loading signal terminal LS when the tape cassette is inserted or removed, the transistors Q 5 and Q 6 are turned off to stop the driving of the melody integrated device 2.

한편, 빨리 보내기가 되감기시에는 플레이단자(PS)에 고전위 신호가 인가되므로 그 고전위 신호는 저항(R5)을 통해 트랜지스터(Q2)를 온시키게 되고. 이에따라 그 트랜지스터(Q2)의 콜렉터에 저전위 신호가 출력된다.On the other hand, since the high potential signal is applied to the play terminal PS during fast forward rewinding, the high potential signal turns on the transistor Q 2 through the resistor R 5 . Accordingly, the low potential signal is output to the collector of the transistor Q 2 .

그러나, 이때 플레이신호단자(PS)에 인가된 고전위 신호는 저항(R6) 및 다이오드(D2), 스위치(SWI), 저항(R10)을 통해 트랜지스터(Q5), (Q6) 를 온시키므로 멜로디집적소자(2)가 구동되어 멜로디음이 출력된다.However, at this time, the high potential signal applied to the play signal terminal PS is applied to the transistors Q 5 and Q 6 through the resistor R 6 , the diode D 2 , the switch SW I , and the resistor R 10 . Since the melody integrated element 2 is driven to output the melody sound.

이후. 빨리보내기가 되감기를 완료하게 되면 캡스턴드라이브 신호단자(CS)에 고전위 신호가 인가되고, 이 고전위 신호는 트랜지스터(Q3)를 온시키므로 그의 콜렉터에 저전위 신호가 출력된다. 이에따라 트랜지스터(Q5), (Q6)가 오프되어 멜로디집적소자(2)의 구동을 중지시키게 된다.after. When the fast forwarding is completed, the high potential signal is applied to the capstan drive signal terminal CS, and the high potential signal turns on the transistor Q 3 so that the low potential signal is output to its collector. As a result, the transistors Q 5 and Q 6 are turned off to stop the driving of the melody integrated device 2.

그리고, 레코드시나 뮤트시에는 레코드신호단자(RS) 및 뮤튜신호단자(MS)에 고진위 신호가 인가되고, 이 고전위 신호는 트랜지스터(Q4)를 온시키므로 그의 콜렉터에 저전위 신호가 출력되어 트랜지스터(Q5), (Q6)를 오프상태로유지시킨다. 이에따라, 레코드시나 뮤티시에는 멜로디집적소자(2)는구동되지 않게된다.At the time of recording or muting, a high-potential signal is applied to the record signal terminal RS and the mute signal terminal MS. Since the high potential signal turns on the transistor Q 4 , a low-potential signal is output to its collector. The transistors Q 5 and Q 6 are kept off. Accordingly, the melody integrated element 2 is not driven at the time of record or mute time.

그리고, 메로디집적소자(2)를 구동시키지 않고자 하는 경우에는 스위치(SW1)를 오프시키면 된다.In the case where the melody integrated element 2 is not driven, the switch SW 1 may be turned off.

이상에서 상세히 설명한 바와 같이 본 고안은 테이프를 넣거나 뺄때, 빨리보내개, 되감기, 무녹화 부분에서의 재생등과 같은 특정모드에서 멜로디음이 출력되므로 사용자에게 보다 유쾌감을 줄 수 있는 이점이 있게된다.As described in detail above, the present invention has an advantage that the melody sound is output in a specific mode such as fast forwarding, rewinding, playing in a non-recorded part, or the like, when the tape is inserted or removed.
