Abstract

PURPOSE:To improve the generality of facsimile equipment, by providing a control section which performs transmission and reception in a procedure following an international standard and another control section which performs transmission and reception in its own peculiar procedure and switching the control sections to each other in accordance with the answer to a call. CONSTITUTION:At the time of data transmission, a timer is started after a calling processing is made to a called subscriber and presence/absence of the reception of a DIS signal or DTC signal from the called subscriber is checked. When either one of the signals is received, it is judged that the called subscriber has a communication system of an international standard and the control system is switched to G3. Then a MODEM for FAX 22 is selectively controlled. When none of the signals is received from the called subscriber, the standard of the called subscriber is judged as that other than the international one. Then the SNRM of a specific signal is transmitted and, when a UA responding signal is received before the time T1 of a timer has come, it is judged that the called subscriber has the same communication system as its own peculiar transmitting system and another MODEM 23 is selectively controlled. Moreover, when no UA signal is received even when the time T1 has elapsed, it is judged that the called subscriber has a transmitting receiving system of a procedure different from that of its own communicating system and the telephone circuit is disconnected.

Description

[Detailed description of the invention] [Industrial Application Field J This invention relates to improvements in facsimile machines.

[Prior Art] A generally known data transmission method for facsimile machines is Recommendation T, 3 of the CCITT (International Telegraph and Telephone Consultative Committee).
This is done in a manner determined by 0. For example, when transmitting data, first call the other party, receive a DIS signal or DTC signal from the other party in this state, and press the send button in this state to send a response signal to the other party. Data transmission is now started.

In addition, when receiving data, when there is a call from the other party, a DIS signal or a DTC signal is transmitted, and when a response signal is received from the other party, data reception processing from the other party is performed.

In contrast, recently, facsimile machines with communication procedures different from those of CCITT are being developed, but conventional facsimile machines of this type have different communication procedures than those of the CCITT. Although it was possible to send and receive data, it was not possible to send and receive data to and from a facsimile machine, which sent and received data according to the CCITT communication system procedures.

[Problems to be Solved by the Invention] As described above, facsimile machines that transmit and receive data using communication method procedures that do not comply with the recommendations of the CCITT in the past, cannot transmit and receive data using communication method procedures that do not comply with the recommendations of the CGI TT. There was a problem that data could not be sent and received with the facsimile machine.

This invention was made in view of the above points, and it is not only a facsimile machine that transmits and receives data using the same communication method procedure as its own, but also a facsimile machine that transmits and receives data using the international standard communication method procedure recommended by CCITT. The present invention aims to provide a facsimile device which can transmit and receive data with other facsimile devices and which can improve its versatility.

[Means for Solving the Problems] The present invention includes a first transmission/reception control means that transmits and receives data to and from the other party using a communication method procedure that conforms to international standards, and a first transmission and reception control means that transmits and receives data to and from the other party using its own unique communication method procedure.

The main processor 11 also includes a FAX modem 22 for transmitting and receiving data with the other party using the international standard communication procedure according to the recommendations of the CCTTT, and a modem 23 for transmitting and receiving data with the other party using its own unique communication procedure.
, telephone circuit 24, etc. are connected. Note that the modem 22 has a speed of 300 bps.

2.400bps, 4,800bps, 7,2
The modem 23 transmits and receives data at 1,200 bps.

The telephone line 24 is connected to a telephone line via one contact of a switching contact circuit 25. A bell detection circuit 26 is connected to this telephone circuit 24.
When a calling signal is input to the telephone circuit 24 via the telephone line, it is detected and the main processor 11 is notified. Further, a handset 27 and a speaker 28 are connected to this telephone circuit 24.

Each modem 22, 23 is connected to a telephone line via the other contact of the switching contact circuit 25.

The main processor 11 is programmed to perform the call processing shown in FIG. 2 when transmitting data. After making a call to the other party, the t-nose first starts a timer and checks whether a DIS signal or DTC signal is received from the other party. When a DIS signal or a DTC signal is received from the other party, the other party receives the CC signal.
It is determined that data is to be transmitted and received using the international standard communication procedure according to the ITT recommendation, and the FAX modem 22 is selectively set to transmit and receive data using the G3 procedure. Further, if no DIS signal or DTC signal is received from the other party, it is determined that the other party follows a communication method procedure of a standard other than the international standard, and an SNRM signal, which is a specific signal, is sent to the other party.

If the UA double signal, which is a response signal, is received from the other party before the timer reaches T1, the other party determines that it can send and receive data using the same communication method procedure as its own unique transmission method. and select modem 23

Further, the main processor 11 is programmed to perform the called process shown in FIG. 3 when receiving data. In other words, when there is a call from the other party, first the timer is started and the other party receives a DIS signal or DTC.
Send a signal. Then, it is checked whether a DCS signal or an SNRM signal is received from the other party.

When a DCS signal is received, the G3 determines that data is to be sent and received using the international standard communication procedure.
The FAX modem 22 is selectively controlled so as to transmit and receive data according to the procedure. Further, when an SNRM signal is received from the other party, it is determined that the other party follows the same communication procedure as the own communication method, and the modem 23 is selected and controlled.

Also, before the timer expires 71 hours, the opponent receives a DO3.
If neither the signal nor the S N RM signal is received, it is determined that the other party is transmitting and receiving data using a communication method procedure different from the own communication method procedure, and the telephone line is cut off.

In this embodiment with such a configuration, when data is to be sent to the other party, the other party requests DIS after calling.
It is checked whether a signal or a DTC signal is received, and if this signal is received, it is determined that the other party complies with the international standard, and the modem 22 is controlled to transmit data to the other party using the 03 method. Furthermore, if no DIS signal or DTC signal is received from the other party, an SNRM signal is sent to the other party to check whether the other party has the same communication method procedure as its own. That is, it is checked whether or not there is a UA double signal received from the other party. If the UA double signal is received, it is determined that the other party is the same device, controls the modem 23, and transmits data to the other party using its own unique communication procedure. Furthermore, if it is determined that the other party is transmitting and receiving data using a communication method procedure that does not comply with international standards or its own unique communication method procedures, the connection with the telephone line is cut off.

In addition, when receiving data from the other party, if there is a calling input from the other party, the other party receives a DIS signal or DTC.
Send a signal. Then, it is checked whether a DCS signal or an SNRM signal is received from the other party. When the DCS signal is received, the modem 22 is controlled and the G3
