Abstract

PURPOSE:To generate an errorless recording picture by storing the transmission speed of the opposite party. CONSTITUTION:A reception terminal connects a line by call originating of a transmission terminal and analyzes a reception signal TSI by a main control part 3 to obtain a telephone number; and when it is registered in the telephone number area of an information storage part 4, the corresponding transmission speed is read out, and signals FTT and CFR are controlled to perform communication based on the read transmission speed. When the telephone number is not registered there, it is registered in the telephone number area of the storage part 4, and the normal reception processing is performed. After the end of communication, the communication information result is stored in the transmission speed information area corresponding to the telephone number in the storage part 4. When the signal TSI is analyzed to obtain the same number as preceding, communication is started at the same transmission speed as preceding. Since communication is performed at the transmission speed adapted to the line without the learning function of a transmitter in this manner at the time of next incoming, the errorless recording picture is obtained.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile machine, and more particularly to a fax machine having a management function of a transmission / reception side device in a reception side device.

[0002]

2. Description of the Related Art A conventional facsimile machine is CCITT
Recommendation T. In the communication means specified in No. 30, TC
The appropriate transmission rate is determined by returning the CFR signal and the FTT signal to the F signal. Also, as a function of the sending side, there was a learning function that remembers the capability of the other party when communicating using a speed dial number etc. and uses that information to determine the transmission rate etc. the next time when communicating. .

[0003]

The above-mentioned conventional facsimile machine, when the transmitting side does not have the learning function, has the CCITT recommendation T.264. TCF specified in 30
Since the transmission rate is determined using the signal, there is a problem that an error occurs during communication even if no error occurs in the TCF signal.

[0004]

A facsimile apparatus according to the present invention comprises an operation section for performing various operations, a communication control section connected to a line for transmitting and receiving a transmission procedure signal and an image signal, and an image signal read from an original. A reading unit that outputs the image signal, an encoder that encodes the image signal, a modulation and demodulation unit that demodulates the image signal received from the line that is modulated to send the image signal encoded to the line, A decoder that decodes the encoded image signal, a recording unit that records the decoded image signal, an information storage unit that stores various kinds of information, and a main unit that is connected to and controls each unit. In a facsimile apparatus having a control unit, a telephone number obtained from a TSI signal received from the line is stored in the information storage unit, and after the communication is completed, the transmission speed is set as the proper transmission capacity of the partner facsimile. Stored, then the telephone number obtained from the incoming TSI signal has means for initiating communication at a transmission speed of the same when the memory and the telephone number the stored.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings. FIG. 1 is a block diagram of an embodiment of the present invention.

The configuration of the present embodiment has a reading section 1 for reading an original document and outputting an image signal, an operation section 2 for various operations, a main control section 3 connected to each of them for controlling, and information for recording various information. It has a recording unit 4, a communication control unit 5 connected to a line 7 for transmitting and receiving a transmission control procedure signal, and a recording unit 6 for recording an image signal. Further, the communication control unit 5 includes a network control circuit 5a,
It has an encoder 5b, an encoder 5c, and a modulator / demodulator 5d.

2 and 3 are a flow chart and a communication sequence diagram for explaining the operation of this embodiment. The receiving terminal, which has received the Ringer signal by the calling of the transmitting terminal, establishes a line connection in step S1 and sends the NSF, CSI, and DIS signals after the CED signal. In step S2, the main control unit of the receiving terminal analyzes the received TSI signal to obtain a telephone number, and if it is already registered in the telephone number area of the information storage unit 4, in S3, the transmission rate corresponding to the telephone number. By reading the transmission rate from the area and controlling the FTT signal and the CFR signal, communication is performed at the transmission rate read from the transmission rate area. Step S
If the telephone number is not registered in 3, the telephone number is registered in the telephone number area of the information storage unit 4 in step S4, and normal reception processing is performed. When the communication is completed, the communication information result is stored in the transmission speed information area corresponding to the telephone number of the information storage unit 4.

[0008]

As described above, according to the present invention, means for analyzing the TSI signal and storing the telephone number information of the partner device,
After the communication is completed, the communication speed is stored as an appropriate transmission capacity of the partner fax machine, and when the next incoming call is received, the TS
Communication is performed at a transmission speed suitable for the line even if the transmitter does not have a learning function by having means for analyzing the I signal and starting the communication at the same transmission speed as the previous time when the same telephone number as the previous time Therefore, it is possible to obtain a recorded image without any error.
