Abstract

PURPOSE:To omit troubles of the operator in the transmission side even if transmission from plural facsimile equipments is concentrated to a center facsimile equipment, by repeating polling to facsimile equipments without interruption unless the center facsimile equipment detects a reset signal indicating that the polling operation is stopped. CONSTITUTION:A center facsimile equipment 1 transmits a transmission instruction DTC to a facsimile equipment 2. The facsimile equipment 2 performs training after transmitting a reception instruction DCS to the center facsimile equipment. When the center facsimile equipment 1 confirms that the facsimile equipment 2 terminates all message preprocedures and can start the message transmission, picture information is transmitted from the facsimile equipment 2 to the center facsimile equipment 1 and is recorded in a recording part 26. After this transmission, the center facsimile equipment 1 disconnects a line to the facsimile equipment 2 and calls a facsimile equipment 3. Thus, the center facsimile equipment 1 repeats polling to facsimile equipments 2, 3, 4, 5, and 6 successively.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] In the present invention, a center facsimile device sequentially connects one line to a plurality of facsimile devices.

The present invention relates to a polling method for a facsimile machine that receives a document.

[Technical background of the invention]

In recent years, office automation of office processing 6X,
! It is rapidly spreading. One of these office automation devices is a facsimile machine, which is widely used.

As a form of use of the facsimile machine, it is possible to consider branch offices 2 scattered throughout the country and document transmission capabilities between the branches and the head office. For example, there is a case where manuscripts created at a branch office are collected at the head office.

In such a case, you can either send the manuscript one by one from one branch office to the main office, or decide on a predetermined time slot, set the manuscript at the branch office during this time slot, and then send the manuscript one by one from one branch office to the main office. The head office must collect messages by polling.

[Problems with background technology]

With the spread of facsimile machines, the amount of manuscripts that the head office must collect has increased dramatically. In other words, most of the time, the center facsimile machine at the head office
It is extremely difficult to find out when one of the facsimile machines at a certain branch office or branch office is in communication with one of them, and the center facsimile machine at the main office, where another branch office or branch office is sending documents, is not in communication state. It is time-consuming and difficult to do so.In order for the central facsimile machine at the head office to poll for a specified period of time, the operator at the branch office must set the document on the facsimile machine at the branch office or branch office within a predetermined time period. In addition, you need to know the time when the document will be sent, and you need to operate it depending on the situation, such as setting the original when polling is in progress, but having to perform two transmission procedures yourself when polling is not in progress. Therefore, it took time and effort to operate the facsimile machine.

Thus, from multiple fax machines.

When transmissions are concentrated to a center facsimile machine located at a head office, etc., the problem that the operator on the sending side takes time and effort to send data is reduced to zero. An object of the present invention is to provide a polling system for a facsimile machine that can save the labor of an operator on the transmitting side even when transmissions to the machine are concentrated.

[Summary of the invention]

The above object of the present invention can be achieved by repeating intermittent polling (vc, J) unless the center facsimile device detects the reset signal Y to stop the polling operation.

[Embodiments of the invention]

The present invention will be described in detail below based on embodiments of the present invention.

Fig. 141 is a diagram showing an embodiment of the present invention, and Fig. 2 shows facsimile machines 2, 3, 4, and 5 installed at a branch office from the center fax machine l used in the embodiment of the present invention.
．． Consider the case of transmitting data to 6.

The center facsimile device is constructed as shown in FIG. Operation unit 21. Jl, the restart signal is the control unit 22r
When this is sent, the open side 1 section 22 stores the destination information 1 of the facsimile machine 2.3゜4.5.6 stored in the storage section 23.
For example, within the phone number.

The storage unit 23 is controlled so that the telephone number of the facsimile machine 2 is sent to the automatic dialing unit 24.

Automatic dialing unit a Based on this telephone number, the network control unit 25
facsimile machine 2 and makes a call to the facsimile machine 2.

On the other hand, only when the facsimile device 5 is in a polling wait state and a document is set, the center facsimile device 1 responds to the Rano call and transmits the contents of the set document to the center facsimile device 1. The procedure for transmitting and receiving signals at this time is shown in FIG. Facsimile machine 2
Assume that the printer is in a polling wait state and a document is set. Center facsimile device 1 (CALL
5TATION), facsimile machine 2 (CALI, i5TATION) automatically receives the call, connects a line with center facsimile machine 1, and sends a function identification signal DISi to center facsimile machine 1. Next, the center facsimile machine 1 transmits a transmission command DTC to the facsimile machine t2. Next, the facsimile machine 2 sends the receiving command DC8-g to the center facsimile machine, and then performs training. From center facsimile device 1 to facsimile device 2.

After all pre-message procedures are completed and a reception preparation confirmation CFR is sent, which confirms that it is OK to start sending a message, image information is sent from the facsimile device 2 to the center facsimile device 1 and recorded in the recording unit 26. Ru.

When the transmission is completed, the line to the facsimile machine 2 is disconnected, and then a call is made to the facsimile machine 3.

If the 1L document is not set, the facsimile machine 2 will not automatically receive the call, and the center facsimile machine L side will also send the call to the primary facsimile machine if the other party does not respond to the call for a predetermined period of time, that is, if it does not receive the call automatically. Make a call to 3.

In this way, the center facsimile machine 1 repeatedly polls the facsimile machines 2.3, 4.5.6 in sequence. FIG. 4 shows a processing flowchart for explaining one embodiment of the present invention.

In other words, the center facsimile device polls only the facsimile device after the document is set, and when communication with one facsimile device is completed, it starts communication with the next facsimile device, and the facsimile device 2 → 3 →
Polling is repeated in the order of 4 → 5 → 6 → 2 → 3.

In the figure, MOD (n, 5) divided by lffni75 1. r
, - indicates the remainder.

Further, when the reset button of the operation unit 21, which is the reset signal generation source, is pressed, a reset signal is sent to the control unit 22,
The above processing flow is interrupted and the processing is stopped. That is, the endless polling mode in which polling is performed repeatedly in sequence is canceled and switched to the normal transmission/reception mode. It is assumed that the reset signal has a higher execution priority than the instructions in the processing flow. Also, when a reset signal is sent, a flag is set, and a routine to reference this flag is provided in the processing flow.

If the flag is set, it may be reset.

In such a case 1 In the normal transmission/reception mode, the reading section 2 is sent from the center facsimile device l to another facsimile device.
It is possible to transmit the image information that is read at 7, or it is also possible to receive the image information that is transmitted from another facsimile machine without polling. The identification number may be sent to the control unit 22 by inputting the identification number.

According to this embodiment, unless a reset signal is sent, 1
The center facsimile machine at the head office repeatedly polls multiple facsimile machines at branch offices without interruption. However, there is no special need for the facsimile machine at the branch office to send the original document as soon as it is generated. The document can be sent to the center facsimile machine simply by setting it on the facsimile machine.

Also, in this embodiment, if no original is set in the facsimile machine at the branch office, v'

Since the communication moves on to the next facsimile device, the line is not used unnecessarily, making it economical.

It doesn't take much time.

〔Effect of the invention〕

According to the present invention, even when transmissions from a plurality of facsimile machines to a center facsimile machine are concentrated, unless the center facsimile machine detects a reset signal, polling is repeated. It can be omitted.
