Abstract

PURPOSE:To transmit a message even from an outside public telephone set by receiving a DTMF signal by push buttons. converting the DTMF signal, etc., into prescribed characters by a character selecting means and outputting them. CONSTITUTION:When a voice band signal (for example, the DTMF signal) is received from a terminal which is not a facsimile equipment and message input processing is terminated, first, a code string stored in a RAM 3 is read out and converted into a JIS code corresponding to the combination of the DTMF signal. In this processing, two successive numeric value of the code string are paired and the JIS code corresponding to each pair is determined based on a conversion table. When the JIS code corresponding to the DTMF signal is determined like this, the JIS code is converted into character data based on CG data stored in a ROM 2, recorded in every line by a recording part 6 and printed out. Thus, the message can be easily sent from the outside public telephone set to the facsimile equipment and outputted.

[Operation] In the facsimile apparatus of the present invention, by receiving a DTMF signal from a button on a public telephone, for example, the DTMF signal or the like is converted into a predetermined character by a character selection means and output.

Therefore, messages can be sent to this facsimile machine even from an external public telephone or the like.

Figures 2 to 4 show the operation of the facsimile machine configured as described above in the message mode, that is, the mode in which a voice band signal (DTMF signal in this example) is received from a terminal other than the facsimile machine and printed out. It is a flowchart.

This operation is performed in accordance with CCITT Recommendation T.30, and is similar to normal facsimile reception operation.
First, after the NCU 16 receives the CI double signal, it returns an identification signal to the calling party and selects the message mode by receiving a response signal thereto.

That is, in this embodiment, as shown in FIG. 2, by detecting the DTMF "#" signal twice in succession instead of the response signal (Sl), the mode is shifted to the message mode (
S2).

In this message mode, the received DTMF signal is
Performs message input processing to be stored in AM3. As shown in Figure 3, first, 10 seconds is set in the timer as the maximum waiting time for the DTMF signal (S l 1), and when this waiting time exceeds the timer (S
12), CML is turned off and line 17 is released from the facsimile machine (Sl, 9).

Also, if a DTMF signal is received before the waiting time elapses (
S13), make sure that this is not a "#" signal twice in a row S14.315), and send this DTMF signal to R
It is stored in a predetermined address of AM3 (S16).

Specifically, among the DTMF signals, "O" to "9" are stored in RAM3 as numerical values as they are, and "1" is stored as "
"A" and "I" are converted to r13J and stored in the RAM3.

Then, advance the address of RAM3 by one (S17
) Return to Sll and repeat the DTMF signal input process,
As a result, a code string of data from rQJ to rBJ is stored in the RAM 3.

In addition, if sis determines that it is a "#" signal twice consecutively, the end code data FFulcRA
Store in M3 (51 B) and turn off CML (S 1
9).

When the message input process is completed as described above, the message input is then printed out.

As shown in FIG. 4, the code string stored in the RAM 3 is first read out and converted into a JIS code corresponding to the combination of DTMF signals (S21). and JIS corresponding to each group.
The code is determined based on the conversion table shown in FIG. In other words, the conversion table shown in Fig. 5 sets the first numerical value of each set of two numerical values as upper data and the latter data as lower data, and converts the JIS corresponding to these combinations.
Select code.

Once the JIS code corresponding to the DTMF signal is determined in this way, this JIS code is converted into character data based on the CG data stored in the ROM 2, recorded line by line by the recording section 6, and printed out.
