In the case of an incoming call, first the handset of the telephone is off-hook, and if the other party is a voice terminal, the call is continued, and when the signal tone of the facsimile machine is recognized, the start button is pressed to start facsimile communication.

[Problem to be solved by the invention] In other words, in the past, the line was switched from the telephone to the facsimile machine as soon as the start button was pressed, so the start button was pressed only after the operator confirmed that the line was connected. In particular, there were the following drawbacks when making calls.

(1) Operator 08 action of pressing the start key is required.

(2) The operator must wait until dialing is complete, that is, until all dial signals have been sent out, and then press the start key, and this waiting time is particularly long in the case of the pulse dial system.

The RAM 3 stores the binary image data read by the reading unit 7 or the binary image data recorded in the recording unit 6, and outputs a signal modulated by the modem 8 to the telephone line 1o via the NCU 9. It stores the binary image data.

Further, the RAM 3 demodulates the analog waveform input from the telephone line 10 via the NCU 9 and the modem 8, and demodulates the analog waveform input from the telephone line 10.
It stores digitized data.

The non-volatile RAM 4 reliably stores data to be saved even when the power to the facsimile machine is cut off. Furthermore, the non-volatile RAM 4 is one of the registration means for registering the name of the other party and the telephone number of the other party in correspondence via the operation unit 12.

Then, based on the program stored in the ROM 2, the CPUI has a function as a transmitting means for transmitting the destination name corresponding to the input destination telephone number to the destination receiver.

CG5 is a ROM that stores characters such as JIS codes and ASCII codes, and extracts character data corresponding to a predetermined code using 2-byte data as necessary under the control of the CPU.

The recording unit 6 is composed of a DMA controller, sub CPU, thermal head, TTL logic IC, etc.
Under the control of I, the recording data stored in the RAM 3 is taken out and recorded and output as a hard copy.

The reading unit 7 is composed of a DMA controller, sub CPU, image sensor, TTL logic IC, etc.
The data read using the CCD is binarized under the control of I, and the binarized data is sequentially sent to the RAM 3. Note that the loading state of the original in the reading section 7 is as follows.
It can be detected by a document sensor such as a photosensor provided on the document conveyance path. The original detection signal is input to the CPUI.

The modem 8 has G3, G2, G1 . It consists of an FM modem and a clock generation circuit connected to these modems.
It modulates the transmission data stored in the RAM 3 under the control of the CPUI and outputs it to the telephone line 10 via the NCU 9.

Furthermore, the modem 8 converts the analog signal of the telephone line 10 into an NC
The data is introduced via U9, modulated and binarized, and the data is stored in the RAM3.

The NCU 9 switches and connects the telephone line to either the modem 8 or the telephone 11 under the control of the CPUI.

The telephone 11 is a telephone integrated with a facsimile device, and a dial operation section is integrated as an operation section 12 described below. Specifically, the telephone set 11 includes a handset, a speech network, a dialer, a numeric keypad or one-touch keys, and the like.

The CPUI detects the pressed states of these keys and controls the above-mentioned parts according to the pressed states.

The display unit 13 is a liquid crystal display that displays 16 digits.
Predetermined characters and the like are displayed under the control of the PUI.

FIG. 2 shows the structure of the line control section of the device shown in FIG.

In FIG. 2, reference numeral 10 is the above-mentioned telephone line, which is connected to the CML relay 22. The CML relay 22 connects the two-wire line 10 to either the hook switch 28 of the telephone or the facsimile side (inside the broken line in the figure).

Hook switch 28 is installed on the line after CML relay 22.
A paging signal detection circuit 27 on the facsimile machine side is also connected thereto. The calling signal detection circuit 27 detects a calling signal from the exchange, and is constructed using a photocoupler or the like.

The paging signal detection output is input to the CPUI.

The modem 8 is connected to the CML relay 22 via a conversion circuit 23 consisting of a hybrid circuit or the like that separates a two-wire transmission/reception signal into four wires.

A dialer 30 is connected via a speech network 29 to a hook switch 28 which is controlled by a handset (not shown). The dialer 30 is controlled by a numeric keypad or one-touch key 31 as a dialing means. Switch 32 and CML relay 22 are CP
Controlled by UI.

The control states of the speech network 29 and dialer 30 are configured to be detectable by the CPUI, and the configuration for this purpose is shown in FIG.

In FIG. 3, the speech network 29 is connected to the line on the hook switch 28 side via a bridge diode 55 for ensuring the polarity of the line. The + side of the diode output is connected to the power supply voltage, and the - side is connected to the ground potential of the device.

The dialer 30 is composed of a known IC or the like, and is capable of outputting a dial signal suitable for either a pulse signal or a DTMF (multifrequency dial tone) signal.

The dialer 30 has a function of outputting a mute signal TMUTE or PMUTE (both negative logic active) to the speech network 29 to mute the dialing signal so that it is not output to the handset connected to the speech network 29. have In the dialer 30 of this embodiment, the mute signal TMUTE is at a low level during the period when a dial signal based on a pulse signal or DTMF signal is output, as shown in FIG. Although not used here, the mute signal PMUTE similarly outputs the same low-level signal during the output period of the dial signal in any dialing method.

Mute signal TMUTE is gate (transistor) 50
The logic is inverted and input to the speech network 29 via . Therefore, the speech network 29 performs a mute operation when the mute input is at a high level.

A photocoupler LED 51 is installed on the collector side of the gate 50.
a is inserted, and notifies the facsimile machine side of the state of the mute signal TMUTE in an insulated state. That is,
The collector and emitter of the phototransistor 51b of this photocoupler are connected to the power supply voltage (+5V) and the ground potential via a resistor, and the potential on the emitter side is set to the transistor 52.
input to the base of The collector potential of the transistor 52 is input to an input/output port 53 connected to the bus of the CPU 1. Therefore, the CPUI knows the state of the mute signal via the input/output port 53 and can identify whether dialing is being performed on the telephone side.

Next, the operation in the above configuration will be explained.

When making a call for voice communication or facsimile communication, the operator performs a dialing operation using the numeric keypad or one-touch key 31 of the telephone.

The numeric keypad or one-touch key 31 outputs a dial signal according to a mode setting of using a pulse signal or a DTMF signal by a switch (not shown) or the like.

At this time, the dialer 30 sends the control signal PMU TE,
Outputs the TMUTE signal to the speech network,
Among these, the mute signal TMUTE becomes low level in synchronization with the dial signal as shown in FIG. The state of this mute signal can be detected by the CPU 1 via the photocoupler and transistor 52 shown in FIG.

Therefore, the CPU detects the dialing operation, and if the document to be sent is loaded in the reading section 7, switches the CML relay 22 to the facsimile device side without detecting the operation of the start key, etc., and starts the facsimile. Start communication.

Next, the above operation will be explained with reference to FIG.

FIG. 5 shows the control procedure of the control program stored in the ROM 2, which is executed by the CPUI of FIG. When starting this procedure, it is assumed that the CPUI connects the CML relay 22 to the hook switch 28 side.

In step St of FIG. 5, C of the facsimile machine is
The PUI first detects the presence or absence of the mute signal TMUTE. When dialing is performed, the LED 51a of the photocoupler shown in FIG. Ru.

If the mute signal TMUTE is present, the process advances to step S2 and waits until the mute signal disappears.

When the mute signal TMUTE disappears, in step S3, a timer constructed from software or the like is set to 10 seconds and started.

In step S4, it is determined whether the mute signal TMUTE continues. If the mute signal continues and the dial signal is in the sending state, the process returns to step S2. When the mute signal is deactivated, the process moves to step S5, and it is determined whether the timer started in step s3 has timed out. If 10 seconds have not elapsed, the process returns to step S4. That is, after dialing is completed, the process moves to step S6 after waiting 10 seconds.

In step S6, the presence or absence of a document is detected. The presence or absence of a document is determined by a document sensor provided in the reading section 7. If no original is loaded, the connection of the CML relay 22 is not changed (connected to the hook switch 28 side) because it is being used as a normal telephone, and the process returns to step Sl.

On the other hand, if there is a document, the CML relay 22 shown in FIG. 2 is switched to the facsimile machine side, and the process moves to step S7 to perform a transmission operation. That is, the reading section 7 reads the image of the original, encodes it, and transmits it via the modem 8.

In addition, the telephone number data used for tire ringing is input from the numeric keypad (31), or when a one-touch key operation or speed dial operation is performed, the telephone number data is input from the non-volatile RA.
The corresponding telephone number data stored in the memory built into M4 or dialer 30 is used.

As described above, use the numeric keypad or one-touch key 31.
By simply performing normal dialing or one-touch dialing, facsimile image transmission can be performed automatically if the document to be transmitted is loaded in the reading section 7.

Furthermore, according to Kimio, it is only necessary to add a photocoupler for detecting the mute signal of the dialer 30 and its peripheral circuit to the conventional configuration, so there is no increase in cost.

Although a facsimile device has been exemplified above, it goes without saying that similar control is possible when combining other data communication devices and telephones. In this case, the data transmission state can be detected through various controls or operating states, such as the loading of a floppy disk containing data to be transmitted or the execution state of software.

Moreover, although the case where the data communication device and the telephone are integrated has been described above, the same technique can be implemented even if these are separate devices and are installed adjacent to each other.

[Effects of the Invention] As is clear from the above, according to the present invention, the telephone is configured of a telephone and a data communication device of a predetermined data communication system integrated with or attached to the telephone, and a call can be made using the dialing means of the telephone. a switching means for connecting a telephone line to either a line on the telephone side having a dialing means or a line on the data communication device side;
Means for detecting whether the telephone is performing tire ringing and means for detecting whether a predetermined member of the data communication device is in a state for transmitting data are provided, and when a call is made, the switching means switches the telephone line to the telephone. in which the dialing of the telephone is detected by the dialing detecting means, and the predetermined member of the data communication device is in a state of performing data communication by the transmitting state detecting means. If a certain condition is detected, the switching means switches the telephone line to the line on the data communication device side and starts data communication.This simple and inexpensive structure allows the state of the data communication device and the timetable to be changed. It is possible to provide an excellent communication device that can automatically start data communication, subject to ring operation, without requiring any more troublesome operations.
