The communication modem 31 has a single frequency signal generation function in addition to the conventional facsimile signal generation function by modulation / demodulation. That is, the communication modem 31 previously associates a single frequency signal with a plurality of digital data, and outputs a single frequency signal corresponding to the digital data when designated by the digital data. In this embodiment, as the scale data, 4-bit digital data and a single frequency signal are associated as shown in Table 1. And in this case, each single-frequency signal corresponds to a scale like'do're'mi '....

By operating a predetermined button on the operation panel 41, the two functions of the communication modem 31 are mode-switched and one function is set.

The control circuit 32 has a storage section. The memory area stores 8-bit melody data DN from address n to address m as shown in FIG.
The upper 4 bits and the lower 4 bits of the melody data DN are scale data dn, dn +1, ... dm (hereinafter collectively referred to as dn) and tone length data ln, ln + 1, ... lm (hereinafter collectively referred to as ln). Has become.

[0015]

[Table 1] In this case, the scale data dn corresponds to the 4-bit digital data of the communication modem 31 (see Table 1). Further, the sound length data ln has a one-to-one correspondence with the signal transmission times ta, tb, ... (Hereinafter, collectively referred to as t), as shown in Table 2. By adjusting the position of the scale data dn or the position of the tone length data In with respect to the digital data DN, a desired melody can be freely generated as a result.

Further, the control circuit 32 is provided with a program for sequentially extracting the melody data DN in accordance with the address and sending the extracted melody data DN to the communication modem 31 to control the communication modem 31. The operation of the facsimile apparatus configured as described above is shown in FIG.
This will be described below with reference to the flowchart shown in FIG.

First, a telephone call is made while the telephone set 43 is connected to the telephone line 42. At this time, when a hold button provided on the operation panel 41 is pressed, the control circuit 32 closes the relay 34, and the telephone line 42 is connected to the telephone set 43 side. To line transformer 3
Switch connection to 3 side (step (hereinafter referred to as ST)
1).

Next, the communication modem 31 is set to the single frequency signal transmission mode (ST2). Then, the head address n of the memory in which the melody data DN shown in FIG. 2 is recorded is written in the counter N on the program (ST
3). In subsequent ST4, the control circuit 32 reads the 8-bit melody data DN recorded in the memory address written in the counter N.

[Table 2]

Then, the control circuit 32 obtains the single frequency signal fN from the read 4-bit scale data dn of the read melody data DN and the conversion table of Table 1 (ST).
5) On the other hand, the transmission time tN in the single frequency signal fN is obtained from the sound length data ln of the lower 4 bits and the conversion table of Table 2 (ST6). Thereafter, the control circuit 32 sets the communication modem so as to generate the single frequency signal fN, and f
The N signal is transmitted (ST7). At this stage, the single frequency signal fN is output to the partner terminal via the relay 34 and the telephone line 42, while the relay 37 and the amplifying circuit are closed if the relay 37 is closed. It is sent to the speaker 35 via 36 to generate a predetermined single sound.

The generation of this single frequency signal fN
The transmission is continuously performed until the transmission time tN obtained by conversion in ST6 is reached (ST8), and when the transmission time tN is reached, the transmission is stopped (ST9).

At this stage, the control circuit 32 is operated by the operation panel 41.
It is checked whether or not the hold stop switch is operated to make a hold stop request (ST10). If a stop request is made, the relay 34 is opened and the telephone line 4
2 is switched from the line transformer 33 side to the telephone set 43 side (ST11), and the operation ends.

When it is determined in ST10 that the stop request is not issued, the memory address stored in the program counter N is incremented by "1" (ST12), and the value of the counter N is stored in the melody data DN. It is checked whether or not the final address m of the memory area has been exceeded (ST13).

At ST13, the value of the counter N is the final address m.
If it is determined that the value does not exceed, the process returns to ST4 and the above-mentioned ST4 to ST12 are performed for the scale data dn + 1 and the note length data ln + 1 of the memory address n + 1.
The above process is repeated until the value of the counter N exceeds the final address m. When it is determined that the value of the counter exceeds the final address m, the process returns to ST3 and the leading scale data dn and the tone length data ln of the melody data DN is returned.
On the other hand, the processes of ST3 to ST12 described above are repeated.

In this way, a plurality of types of single frequency signals fN are sequentially output to the other party's terminal in accordance with a preset procedure to generate a holding tone to notify the other operator of the holding of telephone communication. In this embodiment, the operator on the other side is notified of the hold of the telephone communication, while the operator of the authority is also notified via the speaker 35 so that the hold can be appropriately confirmed.

[0025]

As is apparent from the above description, according to the present invention, digital data is selected in accordance with the procedure that has been set and designated to the communication modem, and a plurality of types of single data are selected from the communication modem. Since the frequency data is generated according to a predetermined procedure, it is possible to generate a melody signal without providing a dedicated melody generating circuit, which has the effect of not increasing cost or space. Further, while the other operator is notified that the telephone communication is on hold, the melody sound is output through the speaker, so that the operator of the own station can appropriately confirm the hold.
