본 고안은 종속기능스위치를 이용하여 카세트 테이프 레코더의 기능을 다양하게 선택할수 있도록 하는 카셋트 테이프 레코더의 기능선택 회로에 관한 것이다.The present invention relates to a function selection circuit of a cassette tape recorder that enables the user to select various functions of a cassette tape recorder using a subordinate function switch.
일반적인 카세트 테이프 레코더의 기능은 더빙(Dubbing)기능, 플레이백기능, 튜너녹음(방송녹음)기능으로 크게 분류되며, 사용자가 기능선택스위치를 더빙모드, 튜너모드, 플레이백모드에 스위칭하여 원하는 기능을 선택한다.General cassette tape recorder functions are divided into dubbing function, playback function, and tuner recording (broadcast recording) function.The user can switch the function selection switch to dubbing mode, tuner mode, and playback mode to select the desired function. Choose.
이러한 기능을 가지는 종래의 회로는 제 1 도에 도시된 바와 같이, 재생용 데크의 재생헤드(H2)가 프리앰프(1)를 통하여 출력앰프(3)에 연결됨과 아울러 녹음/재생용 데크의 녹음/재생헤드(H2)의 일측단자에 연결된 가동(a)이 연결된 기능선택스위치(4)의 더빙단자(b)에 연결되고, 녹음/재생 헤드(H2)의 타측단자가 프리 앰프(2)를 통하여 출력앰프(3)에 연결되며, 수신된 방송신호가 튜너(5)를 통하여 출력앰프(3)에 인가됨과 아울러 기능선택스위치(4)의 튜너단자(d)에 연결된다.In the conventional circuit having this function, as shown in FIG. 1, the playback head H 2 of the playback deck is connected to the output amplifier 3 through the preamplifier 1, A movable (a) connected to one terminal of the recording / playing head (H 2 ) is connected to a dubbing terminal (b) of the function selection switch 4 connected thereto, and the other terminal of the recording / playing head (H 2 ) is connected to a preamplifier ( 2) is connected to the output amplifier (3), the received broadcast signal is applied to the output amplifier (3) via the tuner (5) and is connected to the tuner terminal (d) of the function selection switch (4).
이와같이 구성된 종래의 기능선택회로의 동작을 설명한다.The operation of the conventional function selection circuit configured as described above will be described.

이하 첨부된 도면을 참조하여 본 고안의 실시예를 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
제 2 도는 본 고안의 실시예를 보인 회로도이다. 이에 도시된 바와 같이 일측단자가 접지된 재생헤드(H2)의 타측단자가 저항(R1), 콘덴서(C1)및 외부 마이크단자(6)가 연결된 스위치(SW7)를 통하여 프리앰프(1)에 연결되고, 프리앰프(1)의 출력단자는 기능선택스위치(4)의 더빙단자(b)에 연결됨과 아울러 종속기능스위치(SW3)를 통하여 출력앰프(3)에 연결된다. 녹음/재생헤드(H2)의 일측단자가 기능선택 스위치(4)의 가동접점(a)에 연결되고, 녹음/재생헤드(H2)의 타측단자는 저항(R2)및 외부 마이크단자(7)가 접속된 스위치(SW6)를 통하여 프리앰프(2)에 연결됨과 아울러 콘덴서(C2)를 통하여 일측단자가 저항(R2)에 연결된 스위치(SW8)에 연결된다. 상기 프리앰프(2)의 출력단자는 종속기능스위치(SW4)를 통하여 출력앰프(3)에 연결된다. 수신된 방송신호가 튜너(5)를 및 종속기능스위치(SW5)를 통하여 출력앰프(3)에 인가됨과 아울러 기능선택스위치(4)의 튜너단자(d)에 연결된다. 상기 기능선택스위치(SW)의 플레이백단자(e)는 접지되어 있다.2 is a circuit diagram showing an embodiment of the present invention. As shown therein, the other terminal of the playhead H 2 having one terminal grounded is connected to the preamplifier through a switch SW 7 to which a resistor R 1 , a capacitor C 1 , and an external microphone terminal 6 are connected. 1), the output terminal of the preamplifier (1) is connected to the dubbing terminal (b) of the function selection switch (4) and to the output amplifier (3) through the subordinate function switch (SW 3 ). One terminal of the recording / playback head (H 2 ) is connected to the movable contact (a) of the function selector switch 4, and the other terminal of the recording / playback head (H 2 ) is connected to the resistor (R 2 ) and the external microphone terminal ( 7) is connected to the preamplifier 2 through the connected switch SW 6 , and one terminal is connected to the switch SW 8 connected to the resistor R 2 through a capacitor C 2 .

The received broadcast signal is applied to the output amplifier 3 via the tuner 5 and the slave function switch SW 5 , and is connected to the tuner terminal d of the function selection switch 4. The playback terminal e of the function selection switch SW is grounded.
이와 같이 구성된 본 고안의 회로동작을 설명한다.The circuit operation of the present invention configured as described above will be described.
회로 동작을 설명함에 있어서, 더빙(Dubbing)기능, 플레이백기능, 튜너녹음기능으로 크게 구분하고 이세가지 기능에 종속된 기능들을 설명한다.In describing the circuit operation, the dubbing function, the playback function, and the tuner recording function are largely divided, and the functions dependent on these three functions are explained.
첫째, 기능선택스위치(4)의 가동접점(A)을 더빙단자(B)에 접속시켜 더빙기능을 선택하면, 양 데크(재생용 데크 및 녹음/재생용 데크)가 동시에 동작하여 재생용 데크에 장착된 카세트 테이프로부터 녹음/재생용 데크에 장착된 카세트 테이프에 기록되는 일련의 동작을 수행한다. 이때 더빙을 하면서 라디오 방송을 청취하고자할경우에 종속기능스위치(SW5)를 선택하면 안테나에 수신된 방송신호가 튜너(5), 종속기능스위치(SW5), 출력앰프(3)및 스피크(SP)를 통하여 라디오방송을 청취할 수 있다. 그리고 더빙되는 신호, 즉 재생용 데크에서 재생된 신호를 청취할 경우에는 종속기능스위치(SW3)을 선택한다.First, when the dubbing function is selected by connecting the movable contact (A) of the function selector switch (4) to the dubbing terminal (B), both decks (a deck for playback and a deck for recording / playback) are operated at the same time. Performs a series of operations recorded from the mounted cassette tape to the cassette tape mounted on the deck for recording / playback. At this time, if you want to listen to the radio broadcast while dubbing, if you select the slave function switch (SW 5 ), the broadcast signal received by the antenna is tuner (5), slave function switch (SW 5 ), the output amplifier (3) and the speaker ( You can listen to radio stations through SP). When listening to the signal to be dubbed, that is, the signal reproduced from the playback deck, the subordinate function switch SW 3 is selected.
둘째, 기능선택스위치(4)를 절환하여 가동접점(a)을 플레이백단자(c)에 접속시켜 플레이백기능을 선택하면 각 데크가 독립적으로 동작 하여 (사용중인 어느한 데크만이 동작)재생 또는 녹음 동작을 수행한다. 다시 말하면 재생용 테크가 동작중일 경우에는 종속기능스위치(SW3)를 선택하고, 녹음/재생용 데크가 동작중이면 종속 기능스위치(SW4)를 선택하여 재생음을 청취한다.Second, by switching the function selector switch 4, connecting the movable contact (a) to the playback terminal (c) and selecting the playback function, each deck operates independently (only one deck in use is played). Or perform a recording operation. In other words, if the playback tech is in operation, the slave function switch SW 3 is selected. If the recording / playback deck is in operation, the slave function switch SW 4 is selected to listen to the playback sound.
셋째, 기능선택스위치(4)를 절환하여 가동접점(a)을 튜너단자(d)에 접속시키면 수신된 방송신호가 튜너(5)를 통하여 녹음/재생용 데크에 정작된 카세트 테이프에 녹음이 된다. 이때 녹음과 동시에 방송신호를 청취하고자할 경우에 종속기능스위치(SW5)를 선택하면 튜너의 출력이 종속기능스위치(SW5), 출력앰프(3)및 스피크(SP)를 통하여 출력된다. 또한, 종속기능스위치(SW5)가 오픈된 상태에서 종속기능스위치(SW3)를 선택하면, 방송신호를 녹음/재생용 데크에서 녹음하면서 동시에 재생용 데크에서 재생된 신호를 청취하고자 할수 있다.Third, when the movable contact a is connected to the tuner terminal d by switching the function selection switch 4, the received broadcast signal is recorded on the cassette tape arranged on the deck for recording / playback via the tuner 5. . In this case, when the slave function switch SW 5 is selected when the broadcast signal is to be listened to at the same time as the recording, the output of the tuner is output through the slave function switch SW 5 , the output amplifier 3, and the speaker SP. In addition, one can want to listen to the dependent function switch (SW 5) is a Selecting dependent function switch (SW 3) in the open state, while recording a broadcast signal in a recording / playback deck for simultaneously played on playback deck signal.
이와같이 본 고안은 단순한 플레이백이나 녹음기능을 수해와는 종래의 방식과는 달리 종소기능스위치(SW3~SW5)를 사용하여 카세트 테이프 레코더의 기능선택을 다양하게 할수 있다.In this way, unlike the conventional method of performing simple playback or recording functions, the present invention can use a small function switch (SW 3 to SW 5 ) to vary the function selection of the cassette tape recorder.
