Description
제1도는 본 고안 장치의 회로도.1 is a circuit diagram of the device of the present invention.
제2도는 종래 더블 카세트의 작동 모드 절환장치의 개략 구성도.2 is a schematic configuration diagram of an operation mode switching device of a conventional double cassette.
본 고안은 더블 카세트 레코더의 작동 모드 절환 장치에 관한 것으로 특히 아날로그스위치와 단안정 멀티바이브레이터를 설치하여 더빙 모드중에도 튜너모드를 선택할 수 있는 더블 카세트 레코더의 작동 모드 절환장치에 관한 것이다.The present invention relates to an operation mode switching device of a double cassette recorder, and more particularly, to an operation mode switching device of a double cassette recorder capable of selecting a tuner mode even during a dubbing mode by installing an analog switch and a monostable multivibrator.
종래에는 제2도에서 도시된 바와 같이 A,B재생헤드(31,39)의 출력을 각각 증폭기(32,35)를 통하여 재생헤드 출력 선택 스위치(41)의 고정자(a,b)에 각각 연결하고, 스위치(41)의 가동자(c)는 증폭기(33)를 통하여 모드 선택스위치(42)의 고정자 (a)에 연결함과 동시에 튜너(37)의 출력은 모드 선택스위치(42)의 고정자(b)에 연결하며, 스위치(42)의 가동자(c)는 증폭기(34)를 통하여 스피커(38)에 연결함과 동시에 증폭기(36)를 통하여 녹음스위치(43)에 연결하여된 구성으로서 더빙모드를 선택하면 스위치(41)의 가동자(c)는 고정자(a)에 연결되고, 모드 선택 스위치(42)의 가동자(c)는 고정자(a)에 연결되므로 더빙 모드중에는 재생 카세트의 음을 들을 수 있으나, 튜너의 방송 음은 선택할 수 없게되는 단점이 있었다.Conventionally, as shown in FIG. 2, the outputs of the A and B playheads 31 and 39 are connected to the stators a and b of the playhead output selector switch 41 through the amplifiers 32 and 35, respectively. The actuator c of the switch 41 is connected to the stator a of the mode selector switch 42 via the amplifier 33 and the output of the tuner 37 is the stator of the mode selector switch 42. (b), the mover (c) of the switch 42 is connected to the speaker 38 through the amplifier 34 and simultaneously connected to the recording switch 43 through the amplifier 36. When the dubbing mode is selected, the mover (c) of the switch 41 is connected to the stator (a), and the mover (c) of the mode selection switch (42) is connected to the stator (a). You can hear the sound, but the tuner's broadcast sound was not selectable.
본 고안은 이러한 종래의 단점을 해결하기 위하여 모든 선택 스위치의 후단에 아날로그 스위치 및 단안정 멀티바이브 레이터를 설치하여 아날로그 스위치를 제어하므로서 더빙중에도 튜너 출력(방송출력)을 선택할 수 있는 더블 카세트 레코더의 작동 모드 절환장치를 제공하는 것을 목적으로 하는 것으로 이하 첨부된 도면을 참조하면서 본 고안의 구성 및 작용효과를 설명하면 다음과 같다.In order to solve this disadvantage, the present invention operates an analog cassette and a monostable multivibrator installed at the rear of all the select switches to control the analog switches while operating a double cassette recorder that can select a tuner output (broadcast output) during dubbing. It is an object of the present invention to provide a mode switching device will be described below with reference to the accompanying drawings, the configuration and operation of the present invention.
제1도를 참조하면 본 고안 장치는 더블헤드(1,9), 증폭기(2-6), 튜너(17), 재생헤드 출력선택 스위치(11), 모드 선택 스위치(12), 녹음 스위치(13) 및 스피커(8)로 구성된 더블 카세트 레코더에 있어서, 상기 모드 선택 스위치(12)의 가동자(c)를 아날로그스위치(14)의 고정자(a)에 연결하고, 튜너(17)의 출력은 스위치(12)의 고정자(b)와 아날로그스위치(14)의 고정자(b)에 연결하며, 아나로그 스위치(14)의 가동자(c)는 증폭기(4)에 연결하되, 아날로그스위치(14)의 제어단자(d)는 단안정 멀티바이브레이터(16)의 출력에 연결하고, 단안정 멀티바이브레이터(16)의 입력에는 터치스위치(15)를 연결하여된 구성으로서 이러한 본 고안 장치의 작용효과는, 단안정 멀티바이브레이터(16)를 사용하여 터치스위치(15)를 한번 누를때 마다 트랜지스터(TR2)의 출력이 하이 또는 로우로 동작된다.Referring to FIG. 1, the inventive device includes a double head (1, 9), an amplifier (2-6), a tuner (17), a playhead output selection switch (11), a mode selection switch (12), a recording switch (13). In a double cassette recorder consisting of a speaker and a speaker 8, the mover c of the mode selection switch 12 is connected to the stator a of the analog switch 14, and the output of the tuner 17 is switched. The stator (b) of the 12 and the stator (b) of the analog switch (14), and the mover (c) of the analog switch (14) is connected to the amplifier (4). The control terminal (d) is connected to the output of the monostable multivibrator 16 and the touch switch 15 is connected to the input of the monostable multivibrator 16. using a stable multi-vibrator 16 is pressed once each time the touch switch 15, the output of the transistor (TR 2) operating at high or low The.
초기에 전원이 온 상태가 되면 전원(B+)은 저항(R7)과 콘덴서(C3)를 순간적으로 통한후 다이오드(D4)를 통과하여 트랜지스터(TR2)의 베이스에 하이 상태로 인가되므로 트랜지스터(TR2)가 도통되어 그의 콜렉터 출력은 로우가 되며 이때 아날로그 스위치(14)는 카세트 모드로 되어 접점(c,a)이 상호 접속되며 이때 사용자가 더블 카세트를 녹음 또는 재생 상태로 하면 재생헤드(1)에서 검출된 신호는 증폭기 (2)→스위치 (11)→증폭기(3)→스위치(14)→증폭기(4)를 거쳐 스피커(8)를 구동시키게 된다.When the power is initially turned on, the power supply B + is instantaneously passed through the resistor R 7 and the capacitor C 3 , and then applied to the base of the transistor TR 2 in a high state through the diode D 4 . The transistor TR 2 is turned on so that the collector output thereof is low. At this time, the analog switch 14 is in cassette mode, and the contacts c and a are interconnected. The signal detected by the head 1 drives the speaker 8 via the amplifier 2 → switch 11 → amplifier 3 → switch 14 → amplifier 4.
이때 녹음 카세트는 재생헤드(1)에서 검출된 신호를 증폭기(2,3)를 거쳐 녹음 카세트용 증폭기(6)에서 재생신호를 재차 증폭하여 녹음헤드(9)에 녹음된다.At this time, the recording cassette amplifies the playback signal from the recording cassette amplifier 6 again through the amplifiers 2 and 3 and detects the signal detected by the playback head 1 and records the recording head 9.
또한 사용자가 더블 카세트로는 녹음만하고 스피커(8)의 출력을 튜너(방송)음을 선택하고자 할때 터치스위치(15)를 한번 누르면 콘덴서(C1)에 충전된 전압이 방전하여 트랜지스터(TR1)의 콜렉터 전위가 로우가 되고 트랜지스터(TR2)에 베이스 전위도 로우가 된다.In addition, when the user only wants to record with the double cassette and selects the tuner (broadcast) sound of the output of the speaker 8, pressing the touch switch 15 once discharges the voltage charged in the capacitor C 1 to the transistor (TR). The collector potential of 1 ) becomes low and the base potential of the transistor TR 2 also goes low.
따라서 트랜지스터(TR2)의 콜렉터는 하이가 되어 아날로그스위치(14)의 제어단자(d)에 하이 신호가 가해져 아날로그스위치(14)의 가동자(c)가 고정자(b)측으로 절환되어 증폭기(4)에서 튜너(12)의 출력을 증폭하여 스피커(8)를 구동하게 된다.Accordingly, the collector of the transistor TR 2 becomes high, and a high signal is applied to the control terminal d of the analog switch 14 so that the actuator c of the analog switch 14 is switched to the stator b side so that the amplifier 4 Amplifies the output of the tuner 12 to drive the speaker (8).
이때 재생 카세트에서 재생음은 녹음 카세트에만 녹음 되게 되고 튜너(17)의 출력은 녹음 되지 않는다.At this time, the playback sound from the playback cassette is recorded only in the recording cassette, and the output of the tuner 17 is not recorded.
이상에서 설명한 바와 같이 본 고안 장치에 의하면 더빙중에도 튜너의 출력을 선택할 수 있어 중요한 방송내용을 놓치지 않고 청취할 수가 있다.As described above, according to the device of the present invention, the output of the tuner can be selected during dubbing, so that important broadcast contents can be missed.
