Abstract

PURPOSE:To relieve the load of a receiver (host) side by reflecting the presence of multiple address communication onto an NSF signal so as to inform a transmitter of it from a receiver when originals arrives from plural transmitters. CONSTITUTION:An original read by a scanner 1 of a receiver (host) sent from plural transmitters (terminal equipments) periodically is stored in a memory SAF 3 as a multiple address communication document not having destination information. Every time the original is transferred from each terminal equipment, a transmitter identification (TSI) representing the end of multiple address communication is additionally stored in a system memory 4. Moreover, the host receives a token from each terminal equipment to make multiple address communication automatically without any transmission operation. When a prescribed time elapses, the host side prints out a report on which TSIs of the terminal equipments sending the multiple address communication documents and deletes the multiple address communication document. Thus, the confirmation of the multiple address communication transmission and reception is facilitated to relieve the load of the host.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication method for a facsimile device connected to another device via a network, and particularly to a facsimile device (host) for performing broadcast communication.
The present invention relates to a communication method of a facsimile apparatus suitable for reducing the load of the above.

[0002]

2. Description of the Related Art Conventionally, various methods have been proposed for efficiently transmitting a broadcast to each device in a network composed of a plurality of facsimile devices. For example, in the method described in JP-A-2-050650,
By registering the mail information in the mailbox and broadcasting the mail information of the mailbox according to the registered information of the broadcast destination number of the mailbox, it is possible to perform the broadcast communication in units of mailbox. by the way,
When a specific device among the facsimile devices on the network has a role as a host and that device broadcasts to a device having a role as a terminal device (for example, a facsimile device at the head office is regularly operated from a branch office). When the results are reported and the same notification is sent from the head office to each branch office), it is desirable to reduce the load on the host and communicate efficiently, but the above method does not take this point into consideration. Not done.

[0003]

In the above prior art, if a facsimile apparatus having a host-like function broadcasts sequentially or simultaneously to a terminal facsimile apparatus, a heavy load is imposed on the host apparatus. On the contrary, when the terminal side polls and confirms, if the document of the broadcast transmission is not on the host side, the operation becomes useless. An object of the present invention is to improve such problems, reduce the load on a facsimile device (host) that performs broadcast communication, and perform communication of the facsimile device that enables easy broadcast communication and receipt confirmation. To provide a method.

[0004]

In order to achieve the above object, a communication method for a facsimile apparatus of the present invention has a SAF memory for storing image information and a timepiece device.
When the receiver (host facsimile machine) stores image information (broadcast document) with no destination specified, and the receiver receives an incoming call, NSF (Non-Standard)
Facilities) signal to notify the transmitter (facsimile device of the terminal), and after the transmission of its own device, the transmitter passes the transmission right to the receiver to perform the broadcast transmission, and the receiver When the preset allowable time elapses, the transmitter identification (TSI: Transmitting Station Id
(entification) is printed and the broadcast document is automatically deleted.

[0005]

In the present invention, when an original is received from a plurality of transmitters (terminals), the receiver (host) notifies the transmitter by reflecting the presence of the broadcast document in the NSF signal, and the receiver By automatically receiving the transmission right from the transmitter, can perform broadcast transmission without transmission operation. Further, on the host side, after a predetermined time has elapsed, a report in which the TSI of the terminal to which the broadcast document is transferred is printed and the stored image information is deleted, so that the receipt confirmation of the terminal can be easily performed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. 2 is a block diagram of a facsimile apparatus according to an embodiment of the present invention, and FIG. 3 is a diagram showing a method of storing a broadcast document according to an embodiment of the present invention. In FIG. 2, 1 is a scanner for reading an original, 2 is a plotter for outputting received data and a copied image, 3 is a memory (SAF) for accumulating image information, 4 is a system memory, and 5 is encoding / decoding. A system control unit 6 for controlling the entire apparatus, an operation display unit 7 including a keyboard and a CRT, a network control unit 8 and a modem 9. In the present embodiment, a plurality of facsimile devices having the configuration shown in FIG. 2 are connected via a network so that a specific device has a host function. Further, it is assumed that another facsimile machine (terminal) side periodically transmits to the facsimile machine of the host. When the host uses the regular transmission from the terminal to perform the broadcast transmission, the host (receiver) side scans the original read by the scanner 1 with the image information without the destination information (multicast document).
Stored in the SAF 3 as
It stores the information that manages it. That is, as shown in FIG. 3, the file identification code 41 in the system memory 4 indicates that the document is a broadcast document.
2. Set the number of documents, TSI information address, file deletion time 43, etc. Further, the original document identification code 31, the image information address 32, etc. are set in the SAF 3 to store the broadcast document data. Using this document information address 42, the SAF image information of the corresponding document identification code 31 is taken out. The TSI storage area in the system memory 4 has a structure that can be added each time a transfer is performed.

Now, the communication method of this embodiment will be described. FIG. 1 is a sequence diagram showing a communication method of a facsimile apparatus in one embodiment of the present invention, and FIG. 4 is a diagram showing a document erasure report in one embodiment of the present invention. In this embodiment, as shown in FIG. 1, when a receiver (host) receives an incoming call, it searches the file information in the system memory 4 and judges the presence or absence of a broadcast document from the file identification code 41, If there is, it is reflected in the NSF signal in the communication mode setting procedure, and the transmitter (terminal) is notified. As a result, the transmitter stores the fact that there is a broadcast document in the receiver and directly transmits the self-transmitted document as it is. After the transmission is completed, the transmission right is passed to the receiver side, and the process proceeds to the broadcast document extracting process. If there is no broadcast document in the receiver, the transmitter performs call disconnection processing there. On the other hand, when the receiver acquires the transmission right, the TSI of the transmitter is added to the file information in the system memory and the broadcast document is transmitted.

Further, the receiver (host) of this embodiment periodically reads the time from a clock device (not shown in FIG. 2) such as a built-in timer when the broadcast document is created, and the receiver shown in FIG. Compare with the file deletion time 43. As a result, if the file is not in a call and it has reached the erase time,
First, the TSI of the transmitter that has received the broadcast document is read based on the file information, and is sequentially printed out on the plotter 2 as shown in FIG. And after the report output is completed,
Delete the broadcast document. According to the present embodiment, when a plurality of facsimile devices periodically transmit data to the host facsimile device via the network, the host uses the regular transmission and sends the data to each facsimile device without performing a transmission operation. A report document can be sent, and receipt confirmation can be automatically performed by outputting a report.

[0009]

According to the present invention, when a plurality of facsimile devices periodically send data to a host facsimile device via a communication network, the host can use this to facilitate broadcast transmission and receipt confirmation. Therefore, it is possible to reduce the load on the host side.
