Next, the operation of this circuit will be explained with reference to FIGS. 2 and 3.

G1 recording mode (Figures 1 and 2) First, in the case of normal recording, before recording on the terminal (8), the recorded information is summarized in any type, such as report type or letter type. I want the applicant, but I also use the IO key to input an identification number indicating who the applicant is. Then, a tone signal corresponding to this key is generated by the tone encoder in the terminal (8) and transferred to the tone decoder (33) on the recorder (deck) side. The tone decoder (33) decodes the transferred tone signal and sends it to the discriminator (34). However,
In this case, since it is a normal recording that does not require emergency processing, the tone decoder (33) is connected to the terminal T of the system control circuit (7).
The signal supplied to L2 causes the system control circuit (7)
operates the low frequency oscillator (11) and also operates the operation unit (
The mechanical deck part (29) and the motor (30
) to work.

After the audio signal as unit information input from the microphone (8a) of the terminal device (8) is amplified by the amplifier (9), it is supplied to one input side of the adder 0ω, and is also supplied to the low frequency oscillator ( 11) to the other input side of the adder (lO).
A low frequency signal of 0 Hz is supplied and summed. The audio signal on which the low frequency signal has been superimposed is amplified by an amplifier (12) and then supplied to a recording head (11), whereby it is recorded on a recording medium such as a magnetic tape.

While this audio signal is being recorded, the system control circuit (7)
) contains various information about the audio signal, such as recording time and identification (I

), thereby recording data information on the data track. Further, when the recording of the audio signal described above is completed, the operation of the low frequency oscillator (11) is stopped under the control of the system control circuit (7). After recording the data information, the tape is rewound to the leading edge of the data information, that is, after recording of the audio signal is completed, and then stopped. In other words,
All heads are located at the boundary between audio signals and data information. Therefore, the recording state of the tape at this time is as shown in FIG. 2A. In the figure, AT represents an audio trunk, DT represents a data track, and audio signals (MSG
It is shown that a low frequency signal is superimposed on I) and recorded on the audio track AT, and data information is recorded as data 1 for this audio signal.

works, the low frequency signal from the low frequency oscillator (11) is superimposed on the audio signal in the adder 0ω, and the recording head (1)
recorded on the audio track.

At this time, the erasing head (6) passes through the part where the data information in FIG. 2A is recorded, so once this data 1
will be deleted. Further, when an audio signal is recorded on an audio track, various information regarding this audio signal is stored in the memory (20) as data information by the system control circuit (7), as described above.

Then, when the recording of the audio signal is finished, the memory
(20) Along with the previous data, that is, the data for the audio signal (MSGI), the next audio signal (
Data for MSG2) is read from the memory (20), converted into a recording formant by a data generator (22), and recorded on a data track via a driver (23) and a recording head (4). At this time as well, after recording the data information, the tape is rewound to the leading edge of the data information and then stopped, waiting for the next audio signal to be recorded. The state of the tape at this time is shown in FIG. 2B. From the figure, the data information for the audio signal (MSCI) and the data information for the next audio signal (MAG2) are combined with data 1 and data 2, and data track D corresponds to the end of the next audio signal (MSG2).
It can be seen that it is recorded on the T side.

In this way, each audio signal is sequentially recorded as unit information on the audio track of the tape, and the data information corresponding to each of these audio signals is collected and recorded on the data track side corresponding to the end of the last recorded audio signal. recorded in

The state of the tape at this time is shown in FIG. 2C.

Note that the above is for normal recording, but for recording that requires emergency processing, the following procedure is performed. That is, a predetermined priority number is input using the 10 key on the terminal (8). Then, a tone signal corresponding to this key is generated by the tone encoder, and the tone signal is generated by the tone decoder (33) on the recorder (deck) side.
) will be forwarded to. The tone decoder (33) decodes the transferred tone signal and sends it to the discriminator (34). 8
The m-separator (34) determines that the record requires urgent processing, and supplies its output to the terminal T11 of the system control circuit (7). The system control circuit (7) uses a priority lamp (see Fig. 5) included in the display section (21c) of the display device (21) to indicate that what is currently being recorded is of content that requires urgent processing.

Then, the playback head (2) scans the audio track, and the low-frequency signal (20Hz) superimposed on the audio signal supplied through the amplifier (13) is detected by the low-pass filter (15), and this low-frequency signal is recorded. Wrap tape around the unmarked areas. At this time, the head will be located at the boundary between the audio signal and data information.

Then, by scanning the data track with the playback head (5), the playback signal of the playback head (5) is extracted via the amplifier (24) and the waveform shaper (25).
Data information is read out using this reproduction signal and stored in the memory (20) via the system control circuit (7). As shown in FIG. 3, the memory (20) stores all data information for each audio signal and unit data information for each audio signal. That is, as the total data information, the number of calls indicating how many times the audio signal was recorded as unit information and the total recording time are stored. In addition, the unit data information includes the recording time of the audio signal,
