Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a facsimile machine capable of providing a service in which the same image can be obtained as a plurality of hard copies on the receiving side according to an instruction from the sending side.

■Prior art In recent years, telematics services (
Teletex, G4FAX, mixed mode terminals), etc. have been researched, and their services and control procedures (protocols) are almost being decided.

In telematics services, conventional Gl, G2. G3
High-performance services that are difficult to achieve with fax machines are now possible.

Conventionally, when a plurality of hard copies received by facsimile communication are required, the reproduction images that have been received and printed out are copied by a copying machine to obtain the required number of copies.

■Purpose The present invention solves the above-mentioned conventional problems.The transmitting side sends to the receiving side data such as designation of the number of hard copies to be printed out of the received image, distribution destination, etc. It is an object of the present invention to provide a facsimile device that enables a new service of outputting multiple copies of the same received image using a receiving facsimile terminal.

■Configuration FIG. 1 shows the configuration of the facsimile terminal according to the present invention, where 1 is a transmitting step motor, 2 is a receiving step motor,
3 is a reading section, 4 is a recording section, 5 is a system control unit,
6 is a communication control unit, 7 is an operator interface unit, 8 is a line, 51 is a line memory, 52 is an encoding/decoding unit, 53 is a screen memory, 54 is a buffer memory, 55 is a character-code memory, and 61 is a flow buffer. It is.

In general, when trying to increase the efficiency of line usage in communications, it is necessary to send data to input/output devices and lines.

In facsimile, a line memory 51, a buffer memory 54, a flow buffer 61, etc. are required in a facsimile machine in which buffering is performed using a memory or the like in a system for receiving data from a line.

In the system shown in the figure, a system control unit 5 controls a communication control unit 6, a reading section 3. It controls the recording section 4 and operator interface unit 7. Also, within the system control unit 5, there is a coder that suppresses redundancy from the image information from the reading section 3 and generates encoded data, and a coder that decodes the encoded received data and converts it into the original image information. I have a decoder to play it. The coder and decoder are collectively referred to as an encoding/decoding section 52.

The above is sufficient for normal image information transmission and reception, but for high functionality, it has a screen memory 53 and a character code memory 55 for character communication.

The encoding/decoding section 52 includes a character generator that converts character codes into image information Pea.

Screen memory 53. The buffer memory 54 and the character code memory 55 are logical divisions, and are physically one.

The communication control unit 6 executes a control procedure for communicating with a partner device through the line 8 in response to a command from the system control unit 5.

The 64 procedure is a hierarchical procedure based on the ISO 7 layer O5I model.

FIG. 2 shows an example of a control procedure for transporting two normal documents in a G4 facsimile.

The flow of the control procedure for normal image signal transmission and reception will be described below.

■Call connection settings Generally, the procedure for establishing a call with the other party using the network provided by the carrier (in Japan, the Telephone and Telecommunications Public Corporation) is carried out.

Network used (PSTN, PSDN, C3DN
, l5DN, (INS)).

In Japan, INS is being tested in model areas.

■ Data link layer settings The data link layer is H
DLC (High 1 level Data Link
Control procedures).

A link layer connection is established using SABM (Sat ABM) mode and υA (Unnumbered Accept).

■ Transport layer settings The transport layer is TCR (Transport Connection
Request).

TCA (Transport Connection)
Establish a connection using (Accept).

Also, the data block size of each device is negotiated here, and the number of octets of the data block used during communication (
number of bytes).

■ Session layer settings CSS (CC55 (Co 5ession 5tart)
)R5SP(Response 5ession 5t

)) Add IEADER and pass it to the lower layer,
It is sent to the line as image information. (HEADER processing is executed in each layer even in the lower layer.) Transmission: Image data from the reading unit 3 enters the line memory 51, is encoded by the encoder/decoder 52, and stored in the buffer memory 54. . The data in the buffer memory 54 is sent to the communication control unit 6 and stored in its flow buffer 61. As a result, the communication control unit 6 passes the encoded data that has entered the flow buffer 61 to the document layer, processes the HEADER, and transfers it to the line 8.
send to.

During transmission, the line memory 51 and buffer memory 54 perform buffering for reading speed and encoding/decoding speed, and the buffer memory 54 and flow buffer 61 perform buffering for encoding/decoding speed and line speed.

Reception: Data input from the line 8 is removed from the HEADHH at each layer within the communication control unit 6, and stored in the flow buffer 61 as encoded data.

The encoded data in the flow buffer 61 is transferred to the buffer memory 54, decoded by the encoder/decoder 52, and transferred to the line memory 51. Then, it is recorded and reproduced by the recording section 4.

During reception, the flow buffer 61 and buffer memory 54 perform buffering between line speed and encoding/decoding speed. And line memory 51
The buffer memory 54 performs buffering between the recording speed and the encoding/decoding speed.

■ Page boundaries and end of document ■ In image information transfer, when the transmission of the first page is completed If there are still documents to be sent, CDPB (Go

■ End of session C5E (Command 5ession End).

R5EP (Response 5ession End
The session connection is terminated using Po5itive.

The end of the transport layer is simultaneous with the end of the session layer.

■ Link layer end DISC (Dis Connect), U^ (IJnn
The link layer connection is released by ``Umbered Accept''.

[Phase] Call disconnection setting - When communication ends, the call on the held line is released. The procedure for this is defined depending on the network used.

The control procedure using C/R (command/response) for a normal document has been described above, and next, an example of a procedure for a service for copying and outputting an image signal according to specifications from the sending side will be described.

FIG. 3 shows an example of the procedure for the received image copy output service according to the present invention, and shows a case where a single sheet original is received and a copy is output.

In this example, when setting a session, (command session start C5S, !response session °
Start Positive R55P) executes this service if the partner terminal negotiates a parameter indicating the presence or absence of the screen memory 53.

To implement the above-mentioned service, the following specifications and notifications are required in one communication control procedure.

(a) Information specifying the number of hard copies to be made and the distribution destination of the received copied images.

(b) The sending side specifies which pages to copy during continuous sending;
That is, it is necessary to specify which page is to be stored in the screen memory 53 in FIG. 1.

In this example, (a) is an operator document (OP-DOC) using the document type parameter.

In other words, the operator document (OP-
DOC) and notify the other party, followed by CDUI.
(Command Document User Information) The number-of-copies parameter and the address name character code of the distribution destination section, such as the code indicating the copy-out distribution destination, are transmitted to the user area. This is data specified by the operator manually prior to transmission. This received data is once transferred to the character code memory 55 shown in Fig. 1, and then, when copying out (local mode), it is added to the beginning (predetermined position) of the image information stored in the screen memory 53 and printed out. do.

(b) is taken into consideration during transportation, and the above-mentioned service is performed by copying and outputting only the first page or, during this service, all pages. In some cases, it may not be necessary.

Here, one of the pages to be sent continuously is used as a copy output,
FIG. 3 shows the case of single feeding, which is an example of copying and outputting the first page.

During transportation, use the CDPB (Command Document Page Boundary) shown in Figure 2.

Then, a parameter indicating an attribute indicating whether to store the subsequent image information in the screen memory 53, print it out immediately, or print it immediately after storage is added and notified to the receiving terminal.

As a result, in the receiving terminal, if there are store parameters, they are stored in the ill-th screen memory 53, and after the end of communication (referred to as local mode), the encoded data stored in the screen memory 53 is first opened as an op-oooc. (operator
The contents of the character code memory 55 received and stored in the document are reproduced through the encoder/decoder 52, and the necessary number of hard copies are output.

At this time, the distribution destination data stored in the character code memory 55 is converted into image information Peg by C, . . . G (character generator) and added to the beginning of the reproduced image.

Furthermore, as described here, by notifying the attributes of the signal data following each page break, it can also be used for services such as confidential transmission and transfer.

(Effects) As explained above, in the present invention, the sending side sends data such as designation of the number of hard copies of the received image to be printed out and distribution destination to the receiving side.

It is possible to provide a facsimile device that enables a new service in which a receiving facsimile terminal outputs multiple copies of the same received image, and the practical effects are extremely large.
