Recently, audio signals recorded on cassette tapes
There are double cassette tape recording and playback devices on the market that are designed to allow easy dubbing in the first place. ◎There is a dubbing selector switch for dubbing, and when this dubbing selector switch is operated, the playback signal output end of the playback mechanism and the recording signal input end of the bell sound mechanism are connected. I'm trying to be like that. When dubbing, first the cassette tape on which the audio signal has been recorded is loaded into the playback mechanism Kli, and the cassette tape to be recorded is then loaded into the bell mechanism.
After setting the playback mechanism to playback mode and set the recording mechanism to recording mode, operate the dubbing switch.
By the way, the above-mentioned double cassette tape recording and playback device not only performs dubbing, but also outputs the audio signal played by the playback mechanism to the outside, and also outputs the audio signal that is input from the outside. It is also possible to record audio signals onto a cassette tape using a recording mechanism. However, when trying to output the audio signal reproduced by the reproduction mechanism to the outside, if the dubbing switch is switched to dubbing ilK, the reproduced audio signal cannot be output to the outside. When trying to record an audio signal, if the dubbing switch is set to dubbing, recording will not be possible.
Furthermore, when attempting to dub, dubbing cannot be performed unless the dubbing selector switch is set to dubbing mode. Therefore, in conventional double cassette tape recording and playback devices, dubbing switch operation is complicated. However, when dubbing, it is necessary to perform extremely complicated operations such as setting the playback mechanism to playback mode, setting the recording mechanism to record mode, and then operating the dubbing switch, which is a disadvantage in that the operability is poor. was there.

Therefore, the main purpose of the present invention is to provide a cassette chip recording system that allows dubbing and recording with extremely simple operations without requiring the above-mentioned complicated operations. To summarize the present invention, a recording command means and a copy recording command means are provided, and when the recording command means is operated, the auto-ringing mechanism is set to a state capable of making a bell sound. , connect the external signal input layer to the recording signal input end of the recording mechanism. In response to the operation of the copy recording command means, the playback mechanism is set to a playable state, the recording mechanism is set to a bell tone, and the playback waiaos raw signal is output. The object of this invention and other objects and features will become clearer from the detailed description given below with reference to the drawings. ◎ The diagram is of this invention! iI! In the @configuration, which is a schematic block diagram of Jull, playback mall is a mechanism for playing back audio signals recorded on a cassette tape, and is a well-known mechanism. A mechanism for recording audio signals onto a cassette tape, which is also conventionally known and common. A drive control 6 is provided in connection with the playback device and the recording@@2. This dofig control dial 6 is used to set the playback device to a playable state or to set the chime mechanism 2 to a recordable state in accordance with the command of the operation button 3. Although such a drive control 6 is conventionally known, it is constituted by, for example, a logic circuit.The operation button 3 is a dubbing switch 4 as a copying/recording command means, which is a feature of the present invention. and a recording switch 5 as a recording command means.When the dubbing switch 4 is operated, the drive control key 6 sets the playback mechanism 1 to the playback enabled state and also sets the recording mechanism 2 to the sickle enabled - general state jI.
When the recording switch S is operated, the drive control 6 sets only the recording mode w2 to a recordable state.

Next, I will explain Kla's work in detail. First, when dubbing, attach the cassette on which the audio signal has been recorded to the playback mechanism IK, and then attach the cassette you are about to record to the silver f mechanism 2. Then, operate the dubbing switch 4. The control 6 sets the playback mechanism 5 to the playable state M in response to a command from the dubbing switch 4, and sets the recorder m2 to the recordable state.Furthermore, in response to the dubbing switch 4 being operated, An H level signal is applied to the J input terminal of the Aritz flop 11. At this time, the tail input terminal is L
When the level reaches h0, the JK flip-flop is set and its Qa output terminal becomes H level.
The level signal is applied to the control input terminal C of the analog switch 9. Then, the analog switch 9 has a low threshold impedance between its input end Si and output end Si.
The contacts of the so-called mechanical switch are closed. Therefore, the audio signal played by the playback mechanism IK is given to the recording mechanism 2. This causes the playback mechanism I to play back and record the friend audio signal. Machine '11
You can dub with 12.

That is, by simply operating the dubbing switch 4, the player Ill is set to the re-disappearable state m and the recorder WZt is set to the active state liK, and the audio signal reproduced by the player Ill is input to the recording mechanism engineer. Therefore, it is possible to omit the complicated operation of operating the playback mechanism l and the recorder mar separately and operating the dubbing switch as in the past. When recording the input audio signal, the recording switch 5 is operated. Then, the drive control device turns the recording mechanism 20 into recording enabled state.
11 ◎At the same time, the input terminal KH level signal is input to JK7 flip flop 150 ◎At this time, the J input terminal is at L level ・This rounding, the Qb output terminal of JK flip 7 becomes H level, and the Qa output terminal becomes L level. When the Qb output terminal becomes H level, the threshold impedance between the analog switch 100 input terminal S1 and the output terminal 86 becomes low, and the external signal input terminal 7
A friend audio signal is input to the recording mechanism 2 via the analog switch 10'. Therefore, recording 1! #1
2 records the loud voice signal input from the outside into the seven cassettes 10. Therefore, even if you want to record, simply operate the recording switch S and the recording mechanism 2 will be activated. setting and the external signal input end can be connected to the recording mechanism 2vc. For this reason, when the dubbing switch is switched to dubbing@IIC as in the conventional case (when you operate the recording switch S, the %fh5!# making chair can be eliminated.

In the above embodiment, one has only a playback mechanism and the other has only a recording mechanism, but this is not restrictive, and it is also possible to use both as mechanisms capable of recording and playing.In this case, the dubbing switch 4 is provided, so that the audio signal played back by the recording and playback mechanism of -10,000 is recorded by the other recording and playback mechanism, and when one dubbing switch is operated, the other recording and playback mechanism plays back the audio signal. According to the present invention, in response to the operation of the copy bell sound commanding means, the reproduction mechanism is set to play the general state of aJ in response to the operation of the copying bell sound command means. The state is set and the recording mechanism is enabled for recording, and the reproduction signal output terminal of the reproduction mechanism is connected to the recording signal input terminal of the recording mechanism, so dubbing can be performed simply by operating the copy recording command Rt. When the recording command means is operated and the recording command means is operated, only the recording mechanism is set to the recording enable state 11 and the external signal input terminal is connected to the recording mechanism, so that the recording command is not activated. Recording can be performed simply by operating R.Therefore, there is no need for the complicated operation of operating each mechanism individually and then operating the dubbing switch as in the past.
