Abstract

PURPOSE:To remove picture information, which are once received in one station, from another arbitrary facsimile station by transmitting the picture information, which are accumulated in a memory, to the station when a specified identifying code and a transmitting command are received from the other station in one facsimile station. CONSTITUTION:An ID code is set in advance and when a facsimile equipment 1 is set to a transferring mode, the receiving picture are once accumulated in an image memory 106. On the other hand, a calling is executed from the other facsimile equipment and the calling is incoming. Then, when the ID code and a transmitting request are received, the accumulated picture information are transmitted to the facsimile equipment. Thus, the picture information to be once received by the facsimile equipment 1 can be removed from the other facsimile equipment in an arbitrary place.

Description

[Detailed description of the invention] [Technical field] The present invention relates to a facsimile communication system.

[Prior Art] One of the methods of facsimile communication is a polling method in which a calling party sends a transmission command to a called party and image information is transmitted from the called party to the calling party. In this polling method, the called party must either set a document in the facsimile machine or store image information in its memory before receiving the transmission command.

Another method of facsimile communication is relay transmission, in which a transmitting station specifies a destination and transmits image information to a relay station, and the relay station transfers the received image information to the specified destination. In this relay transmission, the destination must be determined when the originating station transmits to the relay station.

By the way, for example, when the user is away from the office, there may be a case where the user wants to receive manuscripts sent from various locations to the facsimile machine at the office.

In this case, with the above-mentioned polling method, the document received by the facsimile machine in the office must be placed back into the machine or the image information must be stored in the memory, so it is not possible to receive the document on the go. On the other hand, in relay transmission, the sending side must specify the outgoing destination as the destination in advance, so this cannot be done if the outgoing destination is uncertain.

As described above, the conventional facsimile system has a problem in that image information once received by one facsimile station cannot be retrieved from any other facsimile station.

[Objective] It is an object of the present invention to provide a facsimile communication system that solves the above problems and allows image information once received by one facsimile station to be retrieved from any other facsimile station.

[Configuration] For this purpose, the present invention provides the following features in one facsimile station:
In addition to memorizing a specific identification code in advance, image information received from other facsimile stations is stored in the memory, while when a call arrives from another facsimile station and the above-mentioned specific identification code and transmission command are received, the memory This system is characterized in that the image information stored in a station is transmitted to that station.

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 1 shows a block diagram of a facsimile communication system according to an embodiment of the present invention. In the figure, a facsimile machine 1 is connected to a public telephone line network 2, and to the public telephone line network 2, facsimile machines 3 and 4 as communication destinations are connected. facsimile machine 3,
4 is a known facsimile machine that has been used conventionally. Further, the facsimile device 4 has a function of setting an arbitrary ID code and executing polling reception.

In the facsimile machine 1, the network control bag N101 is connected to a telephone line and performs predetermined call origination and incoming call operations by transmitting a line acquisition 2 selection signal 9 and detecting an incoming call. The modem 102 modulates and demodulates image information and transmits the same, and also transmits various procedure signals in transmission control procedures.

The buffer memory 103 temporarily stores image information to be transmitted and received. The data compression and reproduction bag 511o4 compresses the image information to be transmitted and reproduces the received image information into the original image information data.

The line buffer 105 temporarily stores image information. The image memory 106 stores image information of the transmitted original and received image information.

The data compression/reproduction device 107 compresses image information data when storing the image information in the image memory 106, and reproduces the image information data to the original image information data when reading it out.

The operation unit 108 is used to perform various predetermined operations on the facsimile machine. The system control unit 109
It is a microcomputer system equipped with U109a, RAM 109b, ROM 109c, etc., and controls the above-mentioned parts to execute predetermined operations of this facsimile machine. The RAM 109b is a nonvolatile memory, and stores an ID code arbitrarily set in advance. The ROM 109c stores fixed phrase information that is image information for recording a specific message.

The facsimile machine 1 is also provided with a scanner for reading original images, a plotter for recording images, etc., but these are not shown because they are not related to the operation of this embodiment.

When using the facsimile machine 1 of this embodiment with the above configuration, an ID code is first set. The operator inputs an arbitrary number with predetermined digits as an ID code to the operation unit 108.
Enter more information. The input code is stored in RAM1o9
stored in b.

The facsimile device 1 also has two reception modes: a normal mode in which the received image information is recorded by a plotter, and a normal mode in which the received image information is temporarily stored in the image memory 106 and upon receiving a request from another facsimile device. There is a transfer mode for transferring to that facsimile machine.

The operator operates the operation unit 10g to set a desired reception mode. Here, it is assumed that the transfer mode is set.

In this transfer mode, for example, facsimile device 3
When a call is made to the facsimile device 1 to transmit image information, the network control device 101 detects the incoming call and establishes a line connection. Then, the modem 102 executes a predetermined transmission control procedure with the facsimile device 3 side and receives the image information.

The received image information is temporarily stored in the buffer memory 103, and is restored to the original pixel-by-pixel image information by the data compression/reproduction device 104 and temporarily stored in the line buffer 105. Furthermore, the image information is data compressed by the data compression/reproduction device 107 and stored in the image memo January 06.

After receiving the image information, the network control device 101 disconnects the line.

Next, the operation when transferring the image information stored in the image memory 106 to another facsimile device, for example, the facsimile device 4 will be described.

In this case, first, the facsimile device 4 is set with the same ID code as the ID code set in the facsimile device 1, and is set to polling reception mode, and a call is made to the facsimile device l.

When the facsimile machine 1 receives a call, it connects to the line and sends out a CHD signal and a DIS signal as shown in FIG. Since the facsimile machine 4 is set to polling reception mode, when it receives the DIS signal, the NSC, C
It sends out IG and DTC signals to request the facsimile device 1 to transmit image information.

At this time, the set ID code is transmitted using the CIG signal.

Next, the facsimile machine 1 confirms that the received ID code matches the ID code set in the RAM 109b, and sends out a DO3 signal and a modem training signal. The facsimile machine 4 executes modem training and sends out a CFR signal.

When the facsimile device 1 receives the CFR signal, it reads out the image information stored in the image memory 106 and restores it to the original image information using the data compression/reproduction device 107 .

Further, the image information is compressed by a line buffer 105 using an encoding method compatible with the facsimile machine 4. Then, the modem 102 sends out the modem training signal and the compressed image information PIX. When the transmission of this image information PIX is completed, an EOM signal is transmitted.

When the facsimile device 4 normally receives the image information PIX, it sends out the MCF signal, and the facsimile device 1 receives the DCN signal.
Send a signal to open the line. Further, the facsimile machine @4 receives the DCN signal and releases the line. As a result, the image information received by the facsimile device 1 is recorded in the facsimile device 4.

By the way, in the above operation example, when a transmission request is received from the facsimile machine 4 by polling, the image memory 10
A case may be considered in which a transmission request is received when image information has been stored in 6, but no image information has been stored.

In this case, the call receiving operation is performed in the same manner as above, and the fixed text information stored in the ROM 109c is read out. This fixed phrase information is image information for recording a message such as ``There is no accumulated image information.'' in characters, and this fixed phrase information that is read out is stored in the -time line buffer. 105, and then, like normal image information, the data is compressed and sent out as image information PIX. As a result, the facsimile device 4 records the message and determines that there is no image information.

As described above, according to this embodiment, when 10 codes are set in advance and the facsimile device 1 is set to the transfer mode, received image information is temporarily stored in the image memory 106, while other facsimile devices When a call is made and received from a facsimile machine and an ID code and transmission request are received, the stored image information is multiplied and sent to the facsimile machine.

This makes it possible to retrieve image information once received by the facsimile device l from another facsimile device located at an arbitrary location.

In the above embodiment, when the facsimile device 1 is set to the transfer mode, the received image information is stored in the image information memory and transferred.
Confidential reception is known in which transmitted image information is temporarily stored in an image memory and recorded by inputting an ID code. Therefore, this confidentially transmitted image information may be similarly transferred.

Further, although the ID code is transmitted using a CIG signal, it goes without saying that it can also be transmitted using other signals such as an NSC signal.

[Effects] As described above, according to the present invention, one facsimile station stores a specific identification code in advance, and the image information received from other stations is stored in the memory.
When a call arrives from another station and the above specific identification code and transmission command are received, the image information stored in the memory is sent to that station, so the image information once received by one station can be freely used. from another facsimile station.
