Description

Description: TECHNICAL FIELD The present invention relates to a multi-line response device having a function of creating a response tape for a multi-line response device from an already recorded tape.

[Conventional technology]

An example of a conventional multi-line response device will be described with reference to FIG.

In the figure, 1a to 1n are line connection terminals connected to a large number of telephone lines, 2a to 2n detect whether or not there is an incoming call at the line connection terminals 1a to 1n, and a control circuit 10 described later.
3a, 3b, an incoming call detection circuit that closes the line in response to a command from the computer, connects the line to the tape decks 3a, 3b described later, and detects whether the called party hangs up
Is a two-channel recording / reproducing tape deck for producing the tape shown in FIG. 4 or reproducing the produced tape in response to a command from the control circuit 10 when the incoming detection circuits 2a to 2n detect an incoming call. Here, tape deck 3a, created in 3b, or the tape T to be reproduced as shown in FIG. 4, with the message T ₁ is recorded on one channel, informs the end of message to other channels in the tape T The marker signal T ₂ is recorded.

4a and 4b are marker signals reproduced by the tape decks 3a and 3b.
A marker detection circuit 5 for detecting T ₂ is a marker signal generation circuit for recording the message T ₁ from one of the tape decks 3a and 3b from the external input terminal 6 to the marker signal T ₂ on the other channel, 7,8 is a recording selection switch for selecting one of the tape decks 3a, 3b to be in a recording state,
Reference numeral 9 is a recording start switch for starting recording of the tape decks 3a, 3b selected by the recording selection switches 7, 8.
0 is to drive the tape decks 3a and 3b when the incoming call detection circuits 2a to 2n detect an incoming call, stop the tape decks 3a and 3b when the other party hangs up the telephone, and select the recording. The tape decks 3a and 3b selected by the switches 7 and 8 are set in a recording state at the same time when the recording start switch 9 is turned on, and at the same time when the recording start switch 9 is turned off, the marker signal generating circuit 5 is operated to make a marker signal.
It is a control circuit that makes T ₂ record.

Next, to explain the operation based on the configuration described above,
When an incoming call arrives at any of the line connection terminals 1a to 1n, any of the incoming call detection circuits 2a to 2n detects it. This detection signal is input to the control circuit 10 and the control circuit 10
Sends a command to close the line by the incoming call detection circuits 2a to 2n which have detected the incoming call. At the same time, the tape deck
A command to drive the reproduction of either 3a or 3b is sent, and the message T ₁ is sent to the closed line.

If one line is closed and another line receives an incoming call, the same operation as above
The incoming call detection circuits 2a to 2n that have detected the incoming call are closed, and the other tape decks 3a and 3b are driven to be played back. Connecting.

Then, when the reproduction of the _first message T ₁ is completed,
Since the marker signal T ₂ recorded on another channel is reproduced, the mark detection circuits 4a and 4b detect this marker signal T ₂ and output it to the control circuit 10. When the control circuit 10 detects the marker signal T _{2 a} preset number of times, for example, twice, it controls the incoming call detection circuits 2a to 2n of the line where the same message T ₁ is heard twice to open the line. Further, when all the lines connected to the tape decks 3a and 3b are opened, the drive is stopped by a command from the control circuit 10.

By the way, the response tape T used in the above-mentioned multi-line response device is prepared as follows.

That is, in order to create two response tapes T, set them in the respective tape decks 3a and 3b, and record selection switches 7 and 8
To turn on. Next, when the recording start switch 9 is turned on, the tape decks 3a and 3b are set to the recording state. Therefore, the message T ₁
When you input a signal such as
It is recorded on one channel of the tape T by a and 3b.

When the recording is completed, the recording start switch 9 is turned off, and the control circuit 10 receives the signal and activates the marker signal generating circuit 5. As a result, the marker signal T ₂ is recorded on the other channel of the tape T, and when this recording is completed, the tape decks 3a and 3b are recorded.
To stop the operation of.

[Problems to be solved by the invention]

By the way, in the above-mentioned conventional example, when two response tapes are prepared at one time, there is no problem, but there is an already prepared response tape and this tape is used. To create a tape with the same contents,
The reproduction signal of this response tape must be input to the external input terminal 6 for recording. Therefore, another tape recorder has to be prepared, and there is a problem that the dubbing work is troublesome.

Further, when a tape recorded in stereo is used as a response tape, the stereo signal must be recorded in one channel (because it is necessary to record a marker signal in the other channel). There was a problem that it was more troublesome than the dubbing.

[Object of the Invention]

The present invention is intended to solve the above-mentioned problems, and when one of a plurality of tape decks is used as a recording source and another tape deck is used as a response tape and a stereo recording tape is used as a recording source. Mix stereo signals 1
It is an object of the present invention to provide a multi-line response device having a function of recording on one channel.

[Outline of Invention]

The present invention is intended to achieve the above-mentioned object, and the gist of the present invention is to switch the circuit depending on whether an already recorded tape is monaural recording or stereo recording, and reproduce the reproduced signal of this tape from another tape deck. It is possible to make a response tape by recording by.

Example of Invention

Hereinafter, an embodiment of the present invention will be described with reference to FIG. The same reference numerals as those in the block diagram of the conventional example described above indicate the same portions, and a description thereof will be omitted.

In this embodiment, the difference from the above-mentioned conventional example is that
A mixing circuit 11 for mixing signals from both channels of one tape deck 3b is provided, two relays 12 and 13 are provided, and a dubbing switch 14 and a copy switch 15 are provided.

That is, the mixing circuit 11 is connected to the output of the tape deck 3b, and the contact of the relay 13 is provided between the mixing circuit 11 and one channel of the tape deck 3b and the incoming detection circuits 2a to 2n.
13a is connected, and the contact 12a of the relay 12 is connected between this contact 13a and the contact detection circuits 2a to 2n and the contact 12b of the relay 12, and the input end of one channel of the tape deck 3a and the external input terminal. 6 and the contact 12a are connected to the contact 12a, and the control circuit 10 is connected to the coils of the relays 12 and 13.

The dubbing switch 14 connected to the control circuit 10 is a switch operated when a stereo recorded signal is used as a signal source of the response tape, and when this is operated, the relays 12 and 13 are excited.

In addition, a copy switch connected to the control circuit 10
Reference numeral 15 is a switch operated when the same response tape is created from the tape already created for the response, and when this switch is operated, the relay 12 is excited.

Next, the operation will be described based on the above configuration. First, a dubbing operation for creating a response tape using a stereo-recorded tape (for example, a commercially available music tape) as a signal source will be described.

A stereo recorded tape is set on the tape deck 3b and a new tape is set on the tape deck 3a. Next, when the dubbing switch 14 is turned on and then the recording start switch 9 is turned on, the control circuit
Detecting this, 10 puts the tape deck 3b in the rewinding state and at the same time, puts it in the waiting state. At the same time, the relays 12 and 13 are excited to switch their contacts 12a, 12b and 13a.

Then, the control circuit 10 sets the tape deck 3b in the reproducing state and the tape deck 3a in the recording state, so that the stereo signal reproduced in the tape deck 3b is mixed in the mixing circuit 11 and passed through the contacts 13a, 12a, 12b. Is recorded on one channel of the tape deck 3b. When this recording is completed or when the recording start switch 9 is turned off, the control circuit 10 detects this and stops the reproduction of the tape deck 3b and operates the marker signal generating circuit 5 to operate the marker signal generation circuit 5 so that the tape in the tape deck 3a Record the marker signal T ₂ on another channel. After that, the tape deck 3a is stopped and the dubbing operation ends.

Next, the copy operation for creating the same response tape from the already created response tape will be described. Also in this case, the prepared response tape is set on the tape deck 3b and a new tape is set on the tape deck 3a. Next, when the copy switch 13 is turned on and then the recording start switch 9 is turned on, the convolution circuit 10 is turned on.
When this is detected, the tape deck 3b is rewound and at the same time cueed to the expected state. At the same time relay
Only 12 is excited and its contacts 12a and 12b are switched.

Then, the control circuit 10 sets the tape deck 3b in the reproducing state and the tape deck 3a in the recording state, so that the message T ₁ recorded in one channel of the tape deck 3b is reproduced, and the tape is transmitted via the contacts 12a, 12b. Deck 3
It is input to one channel of a and recorded. At the same time as this copying, the control circuit 10 operates the marker detection circuit 4b to monitor the arrival of the marker signal T ₂ . When this copy is completed, that is, when the marker detection circuit 4b detects the marker signal T ₂ due to the end of the message, the control circuit 10b
Stops the reproduction of the tape deck 3b and operates the marker signal generation circuit 5 to record the marker signal T ₂ on the other channel of the tape in the tape deck 3a. After that, the tape deck 3a is stopped and the copy operation is completed.

In the above-mentioned embodiment, one-to-one dubbing and copying are explained, but as shown in FIG. 2, one tape deck 3b is used for reproduction, and two or more tape decks 3n are used for one-to-n. You can dubb and copy. In this case, the relay 12
Connect contact 12n of.

〔The invention's effect〕

As described above, according to the present invention, it is possible to record from one tape deck to one channel of another tape deck regardless of whether the already recorded tape is monaural recording or stereo recording. Can be created by the multi-line response device itself, and therefore, it is not necessary to prepare one tape deck as in the conventional case, so that the above-mentioned dubbing and copying can be easily and easily performed. is there.
