During the REVERSE or AMS, the recording progress is continuously recorded in the recording playback deck, and the recording information of the playback-only deck cannot be recorded, and the playback, recording, and recording are performed even in the double speed status, FF, REW, and AMS. There was a problem such that the playback side gave a tape to the tape at the double speed and the recording side proceeded without recording at double speed.

따라서 상기와 같은 문제점을 해결하기 위하여 이루어진 본 고안은 리프스위치에 의하여 전원을 공급, 또는 차단하여 재생전용데크가 재생상태일때만 재생데크에 녹음이 진행되도록 하고, 재생데크가 재상상태가 아닐 경우에는 녹음측 데크의 녹음상태를 정지시킬 수 있게하며, 또 녹음, 재생데크 모우터가 동시 더빙시 녹음, 재생데크 모우터의 배속회전을 속도조정부에 의해 저속으로 회전되게 하여 녹음, 재생데크 모우터가 배속회전시 모우터를 정속 상태로 자동변속되게 한 것으로, 이를 첨부도면에 의하여 본 고안을 상세히 설명하면 다음과 같다.Therefore, the present invention made to solve the above problems is to supply or cut off the power by the leaf switch so that the recording proceeds to the playback deck only when the playback-only deck is in the playback state, when the playback deck is not in the re-state It is possible to stop the recording status of the deck on the recording side, and the recording and playback deck motors are rotated at a low speed by the speed control unit when the recording and playback deck motors simultaneously dub. The motor is automatically shifted to the constant speed state when the double speed rotation is described.

It is configured by connecting to the connection point (A).

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

먼저, 기능선택스위치(SF3)를 더빙접점단자(D)위치에 놓고 녹음/재생데크의 녹음버튼을 누르면 리프스위치(SL5), (SL6)가 "온"되고 재생/녹음절환스위치(SR2)는 녹음접점단자(R)로 접속되어 트랜지스터(Q4)의 베이스단자에는 리프스위치(SL3)가 "오프"상태에 있으므로 B전원이 인가되지 않아 트랜지스터(Q4)가 턴"오프"되고 트랜지스터(Q4)의 턴"오프"에 의하여 녹음데크모우터(MB)는 정지상태가 된다.First, when the function selection switch (SF3) is set to the dubbing contact terminal (D) position and the recording button of the recording / playback deck is pressed, the leaf switches SL5 and SL6 are “on” and the playback / recording switching switch SR2 is turned on. Since the leaf switch SL3 is in the " off " state to the base terminal of the transistor Q4, and the B power supply is not applied to the recording contact terminal R, the transistor Q4 is turned off " off " The recording deck motor MB is stopped by turning " off ".

이때 재생측의 테이프에 수록된 정보를 고속감기(FF) 또는 되감기(FEW)로 찾은 후 재생전용데크의 재생버튼을 누르면, 리프스위치(SL3), (SL4)가 모두 "온"되어 B 전원은 "온"된 리프스위치(SL3)와 (SL6)를 통해 흐르게 되는데 리프스위치(SL3)를 통한 B+전원은 녹음접점단자(R)에 위치한 재생/녹음절환스위치(SR2)와 저항(R7)을 통하여 트랜지스터(Q4)의 베이스단자에 가해져 트랜지스터(Q4)가 턴온된다.At this time, if the information recorded on the tape on the playback side is found by fast forward (FF) or rewind (FEW) and then the play button of the playback dedicated deck is pressed, the leaf switches SL3 and SL4 are both "on" and B power is " ON "flows through the leaf switch SL3 and SL6. The B + power supply through the leaf switch SL3 is connected to the regeneration / recording switch SR2 and the resistor R7 located at the recording contact terminal R. The transistor Q4 is turned on by being applied to the base terminal of the transistor Q4.

트랜지스터(Q4)가 턴온됨에 따라 리프스위치(SL6)를 통한 B 전원은 다이오드(D1)와 더빙접점단자(D)에 위치한 기능선택스위치(SF1)를 통해 유니트(UNIT)에 B 전원이 공급됨과 동시에 턴온된 트랜지스커(Q4)의 콜렉터와 에미터단자 및, 더빙 접점단자(D)에 위치한 기능선택스위치(SF1)를 통해 녹음데크모우터(MB)에 인가되어 녹음데크 모우터(MA)가 회전되고, 이와 동시에 B 전원은 다이오드(D2)와 기능선택스위치(SF1)를 통해 유니트(UNIT)에 공급됨과 동시에 재생데크 모우터(MA)에 인가되어 재생데크모우터(MA)가 회전되므로 동시 더빙이 수행된다.As the transistor Q4 is turned on, the B power supply via the leaf switch SL6 is supplied to the unit UNIT through the function selection switch SF1 located at the diode D1 and the dubbing contact terminal D. The recording deck motor (MA) is applied to the recording deck motor (MB) through the collector and emitter terminal of the turned-on transistor (Q4) and the function selection switch (SF1) located at the dubbing contact terminal (D). At the same time, the B power is supplied to the unit (UNIT) through the diode (D2) and the function selector switch (SF1) and simultaneously applied to the regeneration deck motor (MA) to rotate the regeneration deck motor (MA). Dubbing is performed.

이상태에서 FF나 REW보턴을 눌러 CUE(재생중 전진고속), REVIEW(재생중 되감기)시 또는 자동선곡을 행할경우 리프스위치(SL3)는 "오프"되고 리프스위치(SL3)가 "온"이 되므로 녹음 데크모우터(MB)는 "오프"된 리프스위치(SL3)에 의하여 트랜지스터(Q4)의 베이스단자로 B+전원이 차단되어 트랜지스터(Q4)가 턴오프되고 턴오프된 트랜지스터(Q4)에 의해 녹음데크 모우터(MB)는 정지되고, 재생데크모우터(MA)는 리프스위치(SL4)를 통한 B+전원에 의하여 계속 회전하게 된다.In this state, when pressing FF or REW button to perform CUE (forward forward during playback), REVIEW (forward during playback) or auto selection, the leaf switch (SL3) is "off" and the leaf switch (SL3) is "on". The recording deck motor MB is cut off by the + terminal of the transistor Q4 to the base terminal of the transistor Q4 by the leaf switch SL3 turned off, and the transistor Q4 is turned off and turned off by the transistor Q4. The recording deck motor MB is stopped, and the playback deck motor MA continues to rotate by the B + power supply via the leaf switch SL4.

이와 같이 재생전용데크가 재생상태일 때만 재생데크에 녹음이 진행되고, 재생측 데크가 재생상태가 아닐경우에는 녹음측 데크의 녹음상태를 정지시키게 된다.In this manner, recording is performed on the playback deck only when the playback-only deck is in the playback state, and when the playback deck is not in the playback state, the recording state of the recording deck is stopped.

한편 녹음, 재생데크 모우터(MB), (MA)가 동시더빙중에 정, 배속스위치(S1)가 배속위치에 있을 경우 녹음, 재생데크 모우터(MB), (MA)의 배속으로 회전하게 되는데 모우터(MB), (MA)의 배속회전을 저속으로 회전시키기 위해서는 구동부(3)내의 트랜지스터(Q2)를 "온"시켜야 한다.On the other hand, when the recording and playback deck motors (MB) and (MA) are simultaneously dubbing, and the speed switch (S1) is in the double speed position, the recording and playback deck motors (MB) and (MA) rotate at double speed. In order to rotate the double speed rotation of the motors MB and MA at a low speed, the transistor Q2 in the driving unit 3 needs to be turned "on".

그러나 트랜지스터(Q2)의 베이스에는 이미 "온"상태인 리프스위치(SL1)를 통해 B-전원이 가해진 상태이기 때문에 트랜지스터(Q4)가 턴온상태이므로 다이오드(D3)를 통한 B+전원은 즉 "온"상태인 리프스위치(SL5)와 재생, 녹음절환스위치(SR1) 및 기능선택스위치(SF2), 배속접점에 위치한 정, 배속스위치(S), 다이오드(D3)를 통한 B-전원이 녹음데크모우터의 속도 조정부(1)내의 다이오드(D4)와 재생데크 모우터의 속도조정부(2)내의 다이오드(D5)를 통해 흐르지 못하고 턴온된 트랜지스터(Q2)의 콜렉터와 에미터단자 및 저항(R3)을 통하여 그라운드됨으로 접속점(A)에는 노우(LOW)레벨이 되어 속도 조정부(1), (2)내의 트랜지스터(Q3), (Q1)는 접속점(A)의 로우레벨에 의해 턴온되어 녹음, 재생데크모우터(MB), (MA)는 정속으로 자동 변속된다.However, since the transistor Q4 is turned on because B - power is applied to the base of the transistor Q2 through the leaf switch SL1 that is already in the "on" state, the B + power supply through the diode D3 is "on". B - power supply through the leaf switch (SL5) and playback, recording changeover switch (SR1) and function selector switch (SF2), the positive speed switch (S), diode (D3) The collector, emitter terminal, and resistor R3 of the transistor Q2 turned on and not flowing through the diode D4 in the speed adjusting section 1 of the rotor and the diode D5 in the speed adjusting section 2 of the regeneration deck motor. It is grounded through the connection point A to the low level, and the transistors Q3 and Q1 in the speed adjusting units 1 and 2 are turned on by the low level of the connection point A to record and play the deck. (MB) and (MA) are automatically shifted at constant speed.

이상과 같이 본 고안은 리프스위치에 의하여 재생전용데크가 재생상태일때 재생데크에 녹음이 진행되게하고, 재생데크가 재생상태가 아닐 경우에는 녹음체크의 녹음상태를 정지되게 하였으며, 또 녹음, 재생테크모우터가 동시 더빙시 녹음, 재생데크 모우터의 배속회전을 속도조정부에 의해 저속으로 회전시켜 주므로써 재생측데크가 테이프에 무리를 주지 않게 하였으며, 또 테이프에 무녹음이 진행되지 않게하여 제품의 품질을 향상시켜 줌은 물론 제품의 기능을 다양화 시킬 수 있는 이점이 있는 것이다.As described above, the present invention allows recording to be played on the play deck when the play-only deck is in the playing state by the leaf switch, and when the play deck is not in the play state, the recording state of the recording check is stopped. When the woofer simultaneously dubs, the double-speed rotation of the recording and playback deck motor is rotated at a low speed by the speed adjusting unit so that the playback deck does not overload the tape and the recording does not progress on the tape. In addition to improving the performance of the product has the advantage that can be diversified.
