Abstract

PURPOSE:To make the conversion calculation of time difference unnecessary by identifying an installation country identification code sent by an opposite communication equipment, and sending an outgoing time in outgoing origin information after correcting the time to that of the installation country of the opposite communication equipment. CONSTITUTION:A time difference conversion table part 6 calculates the time difference of its own equipment and the opposite communication equipment by a holding table set in advance, and outputs it to a control circuit part 8 by a signal line 107 as a time difference information signal. The control circuit 8 takes the sum of the time difference of its own equipment and that of the opposite communication equipment and the present time, and calculates the present time of the installation country of the opposite communication equipment, and outputs it to an outgoing origin information generation part 4 as the time information signal of the installation country of the opposite communication equipment via a signal line 103. The generation part 4 outputs the outgoing origin information to an encoder circuit 3 as an outgoing origin information output signal via a signal line 102. The circuit 3 outputs it to the opposite equipment via a modem 2 and a line control circuit 1. In such a way, it is possible to make the conversion calculation of the time difference unnecessary.

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a Glfi mode facsimile IJ device by CCITT, and particularly to its information transmission method.

(Prior art) Conventionally, in this type of CCITT GW mode 7Axim') device, even if the other party's machine is located in an overseas country with a time difference with the own machine, the sender information is included in the sender's information. It was configured to unconditionally convert the current time of the country in which it invaded as the transmission time into a picture signal and send it to the communication partner.

For example, FIG. 2 is an explanatory diagram showing an example of a received image of a G1 mode facsimile by CCITTK.

At the head of the image signal of the original to be transmitted, there is provided a column indicating the source name and transmission time as source information.

(Problems to be Solved by the Invention) In the conventional Gl mode facsimile ge# by CCITT described above, since there is no installation identification hood registration area in the non-standard signal NSF, it is difficult to recognize the installation of the communicating party. Unconditionally, the current time between the devices installed was converted into a J-plane signal as the transmission time in the source information, and the signal was sent to the other party's device.

Therefore, when checking the reception time on the communication partner side, there is a drawback that it is necessary to check the time difference with the installation 11 of the other party's device and convert the transmission time in the sender information.

An object of the present invention is to
It is necessary to eliminate the above drawback by identifying the official country identification code in F, correcting the sending time in the sender information to the time of the communication partner Isosetsu Kokuni, and then converting the sending time. Gl facsimile machine configured so that there is no It is about providing.

(Means for Solving the Problems) The Gl facsimile device according to the present invention can identify the non-standard signal NSF as a communication procedure signal in the GIN mode defined by T@IQ based on the CC Engineering TT Recommendation, and transmit The CCITT is capable of transmitting not only the source name but also the time of transmission as source information at the head of the image signal to be sent, and includes a code analysis section, a time difference conversion table section, a time circuit, and a source information creation section. The system is configured to include the following.

The code analysis unit has an inter-installation identification code registration area in the non-standard signal NSF that indicates installation, and is used to identify the inter-installation identification code in the non-standard signal NSF of the overly reliable partner device. be.

The time difference conversion table unit converts the installation country code of the identified overconfident partner device and its own installation country code to the built-in time difference conversion table to determine the installation of the communication partner device and its own installation.
This is to calculate the time difference between

The clock circuit is for calculating the current time at the installation of the other device from the current time indicated by the built-in clock and the calculated time difference.

The sender information creation unit is for inputting the calculated current time of installation of the communication partner device as the sender time in the sender information.

(Example) Next, the present invention will be described in detail with reference to the drawings.

Next, when the control circuit section B outputs the installation identification code of the communication partner machine as an installation information signal to the time difference conversion table section 6 via the signal @106, the time difference conversion table section 6 will The time difference between the
7, the signal is output to the control circuit section 8.

Is the control circuit section 8 the current time? In order to input the current time, a current time output request signal is output to the clock circuit 7 via the signal line 10B. As a result, the clock circuit outputs the current time to the control circuit unit 8 via the signal line 109 as a current time information signal.

The control circuit 8 calculates the current time by adding the time difference between the own device and the communication partner device that has already been input and the current time, and calculates the current time of the installation of the communication partner device, and calculates the time information of the country where the communication partner is installed. It is output as an individual number to the source information creation section 4 via the signal line 103. When the communication procedure protocol before transmitting the image signal is completed, the control circuit unit 8 transmits the source information output command signal to the signal line 1.
