Facsimile apparatus having a mode selection function using the telephone according to the present invention for achieving the above object is a tone signal detecting means for detecting a tone signal, a voice data storage means for storing the voice data for mode selection, from the trunk line DTMF signal detecting means for detecting the input DTMF signal, mode switching means for switching to fax mode or telephone mode according to a predetermined control signal, and voice message about mode selection from the voice data storing means when a tone signal is detected from a trunk line And transmitting the control means for controlling the mode switching means to switch to the selected mode when the DTMF signal for mode selection is received through the DTMF signal detecting means.

According to the present invention having the above-described configuration, when the tone signal is detected through the tone signal detecting means, the control means sends out a voice message for selecting a desired mode from the voice data storing means, and then when the DTMF signal is detected from the trunk line. The mode switching means is controlled to switch to the corresponding mode corresponding to the received DTMF signal.

Therefore, the sender can select and execute a desired mode among the fax mode or the telephone mode through the telephone, thereby realizing a facsimile apparatus that can prevent communication errors due to the absence of the receiver.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 2 is a block diagram showing an internal configuration of a facsimile apparatus having a mode selection function using a telephone according to an embodiment of the present invention, and the same reference numerals are assigned to parts performing the same functions as those of FIG. The detailed description is omitted.

In Fig. 2, reference numeral 21 denotes a tone signal detector for detecting a facsimile tone signal, 22 denotes a DTMF signal detector for detecting a DTMF signal from a trunk line, and 23 denotes voice data in which voice data regarding mode selection is stored. It is a storage unit.

Reference numeral 24 denotes a speaker for outputting a telephone ringing sound, and 25 denotes a speaker for mode selection from the voice data storage unit 23 when a facsimile tone signal is detected through the tone signal detection unit 21. Then, when the DTMF signal for mode selection is received through the DTMF signal detection unit 22, for example, a high or low level signal corresponding thereto is applied to the switching unit 19 so that the relay 19a enters the telephone mode or the fax mode. Control unit to control the transfer.

Next, the operation of the device having the above configuration will be described with reference to the operation flowchart shown in FIG.

The control unit 25 normally applies a low level signal to the switching unit 19 to control the relay 19a so that the connection is connected to the trunk line port. Therefore, the switching unit 19 is external to the fax mode. The document reception standby state in which document data can be received from the server is maintained (step ST1).

Thereafter, when the facsimile tone signal is detected through the tone signal detecting unit 21 (step ST2), the control unit 25 faxes the first button to select a mode, for example, a telephone call from the voice data storage unit 23. If you want to read the voice data, please press the button 2, and then modulated through the modulation and demodulation unit 12 is sent to the trunk line (ST3 step).

Then, if the DTMF signal is not detected for a predetermined time, the control unit 25 returns to the fax mode standby state that can receive the original data (steps ST4 to ST5).

On the other hand, the control unit 25 determines whether the DTMF signal detected by the DTMF signal detection unit 22 is a DTMF signal relating to the telephone mode (step ST6). If it is a related DTMF signal, a low level signal is applied to the switching unit 19 so that the relay 19a is not operated (step ST7). Accordingly, the switching unit 19 is in the fax mode, and when the document data is received through the telephone line, the switching unit 19 is demodulated through the demodulation unit 12 and applied to the control unit 25. Thus, the control unit 25 performs the normal control process of printing the received data via the printing unit 17 (ST8 step).

However, if the signal detected by the DTMF signal detection unit 22 in the step ST6 is a DTMF signal for the telephone mode, the control unit 25 applies a high level signal to the switching unit 19 and the speaker Through 24, the ringing tone is output for a predetermined time, for example, 3 seconds (ST9 step).

The applied high level signal drives the relay 19a of the switching unit 19 so that the switching unit 19 is switched to the telephone mode.

Therefore, when a handset (not shown) is heard by the receiving user who hears the ringing sound through the speaker 24, a call path is formed to make a phone call, and the control unit 25 controls the normal call related to the phone call. Processing is performed (ST10 step).

In addition, the control unit 25 is switched to the original fax mode by applying a low-level signal to the switching unit 19 when the call is turned off due to the end of the call and the handset.

That is, according to the above embodiment, the facsimile apparatus which can arbitrarily select the mode selection of the facsimile apparatus connected to the telephone from the outside can be realized.

In addition, this invention is not limited to the said Example, It can variously deform and implement within the range which does not deviate from the technical summary of this invention.

As described above, according to the present invention, a facsimile apparatus that can cope actively with the reception of data even in the absence of the receiver by allowing the sender to select a telephone mode or a fax mode switching mode in the facsimile apparatus connected to the telephone can be realized. It becomes possible.
