Abstract

PURPOSE:To decrease both the number of times of communication of an input-side terminal for originals and the number of times of communication at the time of distribution after storage by providing a holding means which holds transmission address data and data for readout time in correspondence relation and retrieving the data for readout time allowed to correspond to the same transmission address data on the basis of the transmission address data held in the holding means. CONSTITUTION:A CPU 10 monitors whether or not a PB-MF signal arrives within a prescribed time by using its internal timer and receives transmission address data of each image signal of each original from a PB-MF signal detection part 102 when the PB-MF signal arrives. The CPU 104 determines ID data (data for readout time) so that an area of a storage part 107 for storing image signals of respective originals can be found, and generates a contrast memory table 106A containing the ID data and transmission address data. When there is transmission address data in the contrast memory table 106A, the ID data of the same transmission address data are collected. Then, a changeover switch 101 is placed on the side of a communication control part 103 and a call is made based on said same transmission address data. The PB-MF signal detection part 102 converts the data into data indicating a corresponding number, the start, pause, and end and supplies the converted data to the CPU 104.

Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field 1 of the Invention The present invention relates to a facsimile 5-product exchange device.

[Technical Background of the Invention] Facsimile storage and forwarding devices having a broadcast function have been known in the past. According to this facsimile storage and forwarding device,
Image signals of the same original document are sequentially distributed to a plurality of different destinations.

[Problems with the background art] However, four manuscripts 1 to 1 with contents A, B, C, and D
Regarding No. 4, if the respective transmission destinations are different but sometimes overlap as shown in FIG. 2, it was necessary to input the information four times. When input in this manner, the facsimile storage and forwarding device sends the image signal of document 1 to destination a.

Communication is performed 3 times to destinations c and d, and then communication is performed 6 times to destinations a to f in order to send the image signal of document 2, and so on. No image signals were transmitted. For this reason, the facsimile storage and forwarding device described above has to make calls to the same destination many times, resulting in many unnecessary operations, which is not preferable from the point of view of line utilization.

To deal with this, it is conceivable to select and input documents for each destination at a terminal on the input side for documents 1 to 4. In this way, the number of calls made by the facsimile storage and forwarding device having the broadcast function can be reduced, but the input terminal needs to perform six communications, which increases the number of communications.

In addition, it is necessary to input the same original document many times, and there is a drawback that efficient communication cannot be performed.

[Object of the Invention] The present invention was made in view of the above-mentioned shortcomings of the conventional facsimile storage and forwarding device.The purpose of the present invention is to calculate the number of communications between the terminal on the input side of the document and the number of communications during distribution after storage. The purpose of the present invention is to provide a facsimile storage and forwarding device that can reduce the number of users.

[Summary of the Invention] Accordingly, the present invention includes: a storage unit; a storage control unit that creates readout data for each received image signal corresponding to one page of a document and stores the received image signal in the storage unit; a holding means for detecting transmission destination data of a received image signal corresponding to a one-page original sent from a partner terminal, and holding the transmission destination data and reading data in correspondence with each other; Based on the communication destination data, the readout data associated with the same transmission destination data is searched, and the image signal corresponding to the searched readout data is sent in one communication to the destination indicated by the same transmission destination data. The facsimile storage and forwarding device is configured by including a transmitting means for transmitting data, and the above object is achieved.

[Embodiment of the Invention] FIG. 1 is a block diagram of a communication system including a facsimile storage and forwarding device 100 according to an embodiment of the invention. In the figure, 10 indicates a switching network, 201202,...

01n ~70. is provided. Switches 501-50. is usually placed on the side of the telephones 601 to 60n. Also, telephones 601 to 60. sends out a Pa-MF multiplied signal by button operation.

A changeover switch 101 of a facsimile storage and forwarding device 100 is connected to the line 30 . Changeover switch 101
includes a Pa-MF signal detection section 102 and a communication control section 103.
is connected. The changeover switch 101 is switched under the control of the CPU 104, but is turned to the PB-MF signal detection unit 102 side when not communicating.

CP tJ 104 has ROM105, R, A, M
A storage unit 107 consisting of 2O3, a disk device, etc. is connected.

The CPtJ 104 controls each section based on a program stored in the ROM 105. The PB-MF signal detection unit 102 includes an automatic response function. Further, the communication control unit 103 performs communication using a predetermined protocol under the control of the CP tJ 104. It is assumed that the communication control unit 103 includes coding compression/decoding expansion functions in addition to the modem and NCLJ functions. Accumulation section 107
Image signals and ID data are stored in the RAM 106.
A comparison memory table of ID data and transmission destination data is created.

Further, the PB-MF signal detection unit 102 receives the PB-MF multiplied signal transmitted via the line 30, converts it into data indicating a corresponding number, start, delimiter, and end, and converts the converted data. is given to the CPU 104.

The operation after documents 1 to 4 shown in FIG. 2 are input from the terminal unit 401 will be described below.

As shown in FIG.
), contrast memory table 1 in RAM 10B, which will be described later.
06A to detect whether there is a transmission image signal (202),
If YES, respectively, the reception control shown in FIG. 4 and the transmission control shown in FIG. 5 are performed.

Reception control is performed by making a call from the terminal unit 401.

The CPtJ 104 uses a built-in timer to monitor the arrival of the Pa-MF multiplied signal within a predetermined time (301.302). If the Pa-MF multiplied signal does not arrive within a predetermined period of time, the previous reception process will be performed. When the Pa-MF multiplied signal arrives, the transmission destination data for each image signal of each document is received from the Pa-MF signal detection unit 102 (303). Here, the button operations on the telephone 601 start with the operation of the "#" key, the "Synopsis" key, etc.
The end is indicated, then the number of the original is indicated by operating the numeric keys, the r%J key is operated as a separator, and the transmission destination data is entered by operating the numeric keys of the full dial number (also by facsimile). When the abbreviated dial data can be registered in the storage/exchange device 100, the numeric key operation for the abbreviated dial data is performed, and the same operation is continued using the "J" key as a break.

The CPU 104 determines ID data (data for reading) 8 so as to know the area of the storage unit 107 that stores the image signal of each original, and compares this with the transmission destination data in a memory table 106A as shown in FIG. Create as shown (304)
. In FIG. 6, #1 to #4 are ID data. Next, when "end" is detected (305), the selector switch 101 is moved to the communication control unit 103 side and the process moves to receiving the image signal (30B).
), at this time, the switch 501 is switched in the terminal section 40i. The image signals corresponding to one sheet of the original are stored one after another in a predetermined area of the storage unit 107 as shown in FIG. Pa-MF
Turn to the signal detection unit 102 side and return to the program in the flowchart of FIG.

Next, the transmission control shown in FIG. 5 will be explained. If there is transmission destination data in the comparison memory table 106A (Fig. 6), ID data of the same transmission destination data is collected (401).
). Next, the changeover switch 101 is turned to the communication control unit 103 side, and a call is made based on the same transmission destination data (402). If the other party responds within the specified time (403
), corresponding image signals are read out one after another from the storage unit 107 based on the collected ID data, and these are sent to the communication control unit 103.
(404).

When the transmission of image signals corresponding to all ID data is completed in this way (405), an instruction is given to disconnect the line, the changeover switch 1n1 is turned to the FB-MF signal detection section 102 side, and the data is transferred to the comparison memory table 106. The corresponding data is erased (406) and the process returns to the program shown in FIG.

In this way, according to the present embodiment, by sending the transmission destination data for each document in advance using the PB-MF signal, the terminal unit 40i can send the documents 1 to 4 shown in FIG.
can be transmitted to the facsimile storage and forwarding device 100 in one communication.

Furthermore, the facsimile storage and forwarding device 100 can obtain ID data of image signals to be sent to the same destination using the destination data, and can thereby transmit the corresponding image signals in one communication. Only one communication is required for the destination.

In addition, in the above embodiment, the CPU 104, the ROM 10
5 constitutes a storage means 150, which includes a Pa-MF signal detection section 102, a CPU 104, a ROM 105, and a RAM 1.
06 constitutes the holding means 160, and the communication control section 103, C
The PU 104 and the ROM 105 constitute a transmitting means 170.

Further, in the embodiment, the transmission destination data and the like are transmitted using a PBMF signal, but the above data may be included in a control signal for facsimile communication such as NSS or NSF and transmitted.

When doing this, the communication control unit detects the data and sends it to the CPU.

[Effects of the Invention] As explained above, according to the present invention, the number of communications at the terminal on the input side of the manuscript and the number of communications at the time of distribution after storage are reduced, and efficient facsimile communications can be performed.
