Abstract

PURPOSE:To secure the reception by a specific facsimile equipment matching a sent document by knowing information on the sent document from a SETUP message and ignoring the SETUP when previous specification is performed. CONSTITUTION:When a document to be sent is set on a facsimile equipment 100 on a transmission side, document setting is detected and a central control circuit 2 drives a display control circuit 6 to display the kind of the sent document on a display 7. When a cursor is moved to select a corresponding number, e.g. an item of 'important document', its information is sent out to the other equipment. The facsimile equipment 103 on a reception side, on the other hand, is so set that the equipment is actuated when a document is 'important document' or 'photograph', and the equipment sends ALERT back for SETUP when receiving the code or ignores the SETUP when not. A facsimile equipment 104 is so set that the equipment is actuated when the document is 'confirmation item document' or 'memo-like document'.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile machine using ISDN.

[0002]

2. Description of the Related Art A general call setting for circuit switching in a facsimile apparatus using ISDN is first activated by sending a SETUP (call setting request) message from a calling side. CALL PR with meaning during call setup process
When the call on the called side starts after the transfer of OC (notification of processing for call setup), an ALERT (notification of calling of the called party) message is sent to the caller, and then When the called side responds, a CONN (notification that the called party has answered) message is sent to the calling side, the channel is connected, and communication is started.

The procedure of call setup on the receiving side when the receiving side has a passive bus structure and two or more facsimile devices are connected to the bus will be described. First, the first SET
The UP message is sent from the network side to the terminal side in a broadcast mode unnumbered information (UI) frame. Upon receiving this SETUP, each terminal checks whether or not it can communicate with the facsimile device on the sending side in the first place, that is, the possibility of receiving a call. If the terminal device is a telephone or the like, the communication possibility is not confirmed, so SETUP is ignored. However, the facsimile device confirms the communication possibility, returns ALERT to SETUP, and starts calling. Here, of the two or more facsimile devices, the one that actually communicates is determined by the one with the quickest response and the win. That is, a CONN ACK (confirmation for CONN) is sent from the network to the facsimile apparatus that first issued CONN, and communication is permitted. On the other hand, other facsimile machines that have issued ALERT earlier will be released to these facsimile machines by the exchange of REL and REL COMP.

[0004]

By the way, when two facsimiles are attached to the bus, one of them is of a thermal recording type and the other of them is a plain paper recording type. It may be If it is known in advance that an important document will be sent, it may be desired to receive it with a plain paper recording type facsimile apparatus in which yellowing of the paper is unlikely to occur.

However, as described above, which of the facsimile machines will actually perform communication depends on the win of the quick response, so that the reception by the specific facsimile machine cannot be ensured. In view of the above circumstances, it is an object of the present invention to provide a facsimile device that can ensure reception by a specific facsimile device.

[0006]

In order to solve the above-mentioned problems, a facsimile apparatus according to the present invention determines whether a user operates a reception refusal key or what document is to be transmitted. Characterized by providing means for obtaining the information shown by the SETUP message and ignoring the SETUP when the document to be transmitted corresponds to the document designated in advance as rejecting the reception. There is.

[0007]

According to the above construction, when two or more facsimile machines are attached to the bus and, for example, an important document is to be received by the plain paper facsimile machine, the facsimile machine concerned is required. By turning on the reception refusal key for other facsimile machines, only plain paper facsimile machines will return ALERT to SETUP and the call will be started, so that plain paper facsimile machines will receive important documents without fail. Can be made With respect to a facsimile machine other than the plain paper facsimile machine, for example, by designating an important document as a document whose reception is rejected, the important document is surely received by the plain paper facsimile machine.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The following will describe one embodiment of the present invention with reference to FIGS. FIG. 2 shows a configuration of a line network connecting facsimile machines. The facsimile machine 100 is connected to a DSU (network terminating device) 101, and an ISDN is interposed between this DSU 101 and another DSU 102. In addition, a passive bus configuration is adopted as the wiring form in the DSU 102, and the bus is
Two facsimile devices 103 and 104, a TEL (telephone) 105, and a personal computer 106 are connected.

FIG. 1 shows the facsimile device 100.
1 is a diagram showing a schematic configuration of 103 and 104. This facsimile apparatus is connected to a protocol processing unit 1 connected to an ISDN network, a central control circuit 2 for controlling the entire facsimile apparatus, and a central control circuit 2. A memory 3 and a key identification circuit 4 connected to the central control circuit 2,
Various keys 5 connected to the key identification circuit 4, a display control circuit 6 connected to the central control circuit 2, a display 7 connected to the display control circuit 6, and a CCD line sensor read the contents of the original. The reading unit 8, the encoding unit 9 that encodes the read image data, the decoding unit 10 that decodes the received encoded image data, and the recording unit 11 that records on the recording paper based on the decoded image data. And a selection switch circuit 12 for switching between connecting the encoding unit 9 to the protocol processing unit 1 or connecting the encoding unit 9 to the protocol processing unit 1 in response to a command from the central control circuit 2. ..

The recording unit 11 of the facsimile apparatus 103 is a plain paper recording system for recording on plain paper by an electrophotographic system and has a resolution of 400 dp.
i's are installed while the facsimile machine 104
As the recording unit 11 in the above, a thermal recording type recording unit in which heat is applied to recording paper in dot units by a thermal head and recording is performed, and the resolution is 200 dpi is incorporated.

FIG. 3 shows a facsimile machine 1 on the transmission side.
It is explanatory drawing which shows the content of the individual part user / user information of the SETUP message which 00 issues, and in this message, the user / user information code, the size of content length, a company number, the presence / absence of a discrimination function , The content code of the transmitted document is incorporated. The procedure for inputting this transmission document content code will be described below. First, when the transmission document is set, this document set is detected,
The central control circuit 2 drives the display control circuit 6 to display the type of transmission document on the display 7, as shown in FIG. For example, 1. Send important documents, 2. Confirmation items, normal transmission, 3. Send memo, 4. Display as sending photos.
The user operates the cursor movement keys of the various keys 5 to move the cursor to the position of the corresponding number. Then, after inputting the destination telephone number and pressing the send key, the code corresponding to the number at which the cursor is positioned is incorporated into the individual section user / user information as the transmission document content code, Will be sent.

On the other hand, the facsimile machine 10 on the receiving side
3.104 is set in the user mode at the time of device setting so that it is activated only for a specific transmission document.
For example, the facsimile machine 103 is set to be activated when the transmitted document is "important document" or "photograph". That is, when the SETUP message is received, the transmission document content code in the message is examined, and if this code is a code indicating "important document" and "photograph", ALERT is returned to SETUP. If not, SETUP is ignored. On the other hand, the facsimile apparatus 104 is set so as to be activated when the transmitted document is a “confirmation document” or a “memo writing document”. That is, if the transmission document content code of the received SETUP message is a code indicating "confirmation document" and "document of memo writing level", ALERT is returned to SETUP. Otherwise, SETUP is returned.
Is supposed to be ignored. If no code is included in the transmitted document content code, both facsimile devices 103 and 104 respond, and the one with a quick response is activated and receives.

According to the above construction, by inputting the content of the transmission document at the transmission side, the reception side drives the facsimile apparatus suitable for the transmission document to receive the document. That is, when the transmitted document is an important document or a photograph, it is received by the facsimile device 103 having a high resolution in the plain paper recording method, and thus, the important document which is likely to be filed is less likely to be yellowed. Plain paper also allows photographs to be recorded in high resolution, which allows for proper reception of the transmitted document. On the other hand, when the transmitted document is a confirmation item document or a memo writing document, it is usually discarded after the received document is viewed, and recording is performed on the thermal recording paper at a low resolution.

In the above embodiment, only the specific facsimile machine automatically starts the receiving operation by the user's document selection operation in the transmitting facsimile machine and the document judgment in the receiving facsimile machine. However, only a specific facsimile apparatus may be driven manually by a key operation on the receiving side. That is, the facsimile machine 103.10 on the receiving side
4 is provided with a reception refusal key operated by the user, and when the reception refusal key is turned on, SETUP is intentionally ignored even if the communication possibility is confirmed. As a result, for example, when the user informs the user in advance by telephone or the like that "important documents will be sent from now", the user can send the facsimile data to the facsimile device 10.
By turning on the reception refusal key in 4, the plain paper facsimile apparatus 103 can receive the important document. To cancel the reception refusal mode, the user turns off the reception refusal key or the reception refusal key turns on.
The facsimile machine automatically turns off the reception refusal key after a certain period of time has passed, or the facsimile machine automatically turns off the reception refusal key after a while after intentionally ignoring SETUP. It can be carried out.
