Abstract

PURPOSE: To send a transmission waiting original surely for an intended transmission time by informing it to a sender when a call is received while the transmission waiting original is in existence so as to allow the sender to stop the transmission. CONSTITUTION: A sender side facsimile equipment 10 makes a call to a receiver side facsimile equipment 20 in the case of its transmission. Upon the receipt of the call, the facsimile equipment 20 sends data representing the presence of a transmission waiting original and transmission start time data of the transmission waiting original to the facsimile equipment 10 when the transmission waiting original is stored in a storage section 26. When the facsimile equipment 10 acquires the data representing the existence of the transmission waiting original and the transmission start time data, the facsimile equipment 10 calculates the transmission end time of its transmission waiting original and stops the transmission when the transmission start time is earlier than the transmission end time and sends a transmission interrupt notice to the facsimile equipment 20 and interrupts its channel. The facsimile equipment 10 redials the facsimile equipment 20 after lapse of a prescribed time when the transmission of its image information is stopped to send again the image information of the transmission original whose transmission has been stopped.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile communication system, and more particularly, to a facsimile communication system for properly performing facsimile communication when a receiving facsimile device has an original document for transmission.

[0002]

2. Description of the Related Art In general, a facsimile machine responds to an incoming call, executes a facsimile communication procedure, and receives image information transmitted from a transmitting facsimile machine.

However, the facsimile machine, when receiving a call,
If communication is already in progress, the call is not answered and the transmitting side facsimile device cannot perform facsimile transmission.

In such a case, the transmitting facsimile machine temporarily suspends the transmission operation, shifts to the re-call waiting state, redials after a predetermined time, and performs the transmission operation.

However, in the conventional facsimile apparatus, when the call is waiting for a recall, the display only displays "waiting for redial" or "waiting for a recall" on the display unit. However, there is a problem that the usability of the facsimile device is poor.

[0006] Therefore, the present applicant has previously proposed that, in a facsimile apparatus having a recalling function, when a transmission document is set in the document reading device and waiting for a recalling call, a call is made until the next call is made. A facsimile machine is proposed which is provided with a control means for displaying the time.

According to this facsimile apparatus, the time until the call is recalled is displayed while waiting for the call to be recalled, so that the remaining time until the call can be recalled can be known. The waiting time can be shortened.

[0008]

However, in such a conventional facsimile machine, although the remaining time until the recalling call can be known while waiting for the recalling call, there is an incoming call while waiting for the recalling call. When the number of pages of the received document is large and the reception process is long and the reception is not completed by the recall time, the transmission time due to the recall call is delayed. There was a problem that it could not be sent at the intended sending time.

The above-mentioned problem is not limited to the above-mentioned re-call waiting,
The same occurs in the time designation transmission in which the image information of the transmission document is temporarily stored in the image memory and then the image information of the transmission document is read from the image memory at the designated transmission time and transmitted.

That is, when the image information of the time-specified transmission document is stored in the image memory and a call is received while waiting for the transmission, the facsimile apparatus waiting for the transmission responds to the reception process. However, when the reception time is prolonged and the reception process is not completed at the designated transmission time, there is a problem that the transmission time of the designated transmission time is delayed and the transmission cannot be performed at the intended transmission time.

When such incoming calls occur one after another, the received image information is accumulated in the image memory one after another, the remaining capacity of the image memory is reduced, and the image information of a new transmission original can be accumulated. However, there is a problem that the availability of the image memory is poor.

Therefore, according to the present invention, when an incoming call is received while there is a transmission standby document, the transmission side notifies the transmission side, and the transmission side suspends the transmission operation, so that the image information of the transmission standby document is intended. It is an object of the present invention to provide a facsimile communication system that can be transmitted at any time and can effectively use an image memory.

[0013]

A facsimile communication system of the present invention is a facsimile communication system in which a facsimile communication procedure is executed between facsimile devices to send and receive image information, and a receiving facsimile device receives an incoming call. If there is, at least a transmission document presence / absence notifying means for notifying the transmission side facsimile device of the presence / absence of a transmission standby document,
Upon receiving a notification from the receiving-side facsimile device that there is a document waiting to be transmitted, the transmitting-side facsimile device stops transmission of image information of the transmitting document, and transmission of image information of the transmitting document by the transmission-terminating device. The above-mentioned object is achieved by providing a transmission stop notification means for notifying the reception side facsimile apparatus of the above.

In this case, for example, as described in claim 2, when the transmission side facsimile device stops the transmission of the image information of the transmission original by the transmission stop means, the reception is stopped after a predetermined time has elapsed. A re-transmission unit may be further provided for re-calling the facsimile apparatus on the side and re-transmitting the image information of the transmission document whose transmission has been stopped.

Further, for example, as described in claim 3, the transmitting side facsimile device, when the transmission request operation of the transmission original is performed, selects whether or not the transmission original is an urgent transmission original. Even if the transmission canceling means receives a notification from the receiving side facsimile device that there is a transmission waiting document when the urgent selection means selects the urgent transmission document. The transmission of the image information of the transmission document may be continued.

Further, for example, as described in claim 4, the transmission document presence / absence notifying means of the reception side facsimile device also notifies the transmission side facsimile device of the transmission start time of the transmission standby document, and the transmission side facsimile device. The facsimile apparatus further includes a transmission time calculating means for calculating a transmission end time at which the transmission of the transmission original is completed, and the transmission stopping means has not selected the urgent transmission original by the urgent selecting means. However, when the transmission end time calculated by the transmission time calculating means is earlier than the transmission start time notified from the reception side facsimile device, the transmission of the image information of the transmission original may be continued.

[0017]

According to the facsimile communication system of the present invention,
Upon reception of an incoming call from the transmitting side facsimile apparatus, the receiving side facsimile apparatus checks the presence / absence of a transmission waiting original document, and at least notifies the transmitting side facsimile apparatus of the presence / absence of a transmission standby document by means of the transmission document presence / absence notifying means.

When the transmission side facsimile device receives a notification from the reception side facsimile device that there is a transmission waiting document, the transmission canceling means cancels the transmission of the image information of the transmission document and the transmission cancellation notifying means causes the transmission document to be transmitted. The facsimile machine on the receiving side is notified that the transmission of the image information has been stopped.

Therefore, the facsimile machine on the receiving side is
When there is a transmission standby document, the incoming call can be stopped and the transmission standby document can be surely transmitted at the intended transmission time.

Further, when the image information of the transmission waiting document is stored in the image memory for storing the image information, the incoming call is repeated one after another, and the image information of the received document is stored in the image memory one after another. Therefore, the image information of the transmission standby document that has been transmitted can be deleted from the image memory to effectively use the image memory.

In this case, for example, when the transmission side facsimile device stops the transmission of the image information of the transmission original by the transmission stopping means, the retransmitting means stops the transmission after a predetermined time elapses. By re-calling the received facsimile device and retransmitting the image information of the transmission original document whose transmission has been stopped, the image information of the transmission original document whose transmission has been stopped can be reliably transmitted by re-sending. The usability of the communication system can be improved.

Further, for example, as described in claim 3, when the transmission side facsimile apparatus requests the transmission of the transmission document, the operator selects the transmission document by the urgent selection means. If the transmission stop means selects the urgent transmission original by the urgent selection means, the transmission is performed even if the notification of the transmission standby original is received from the receiving facsimile machine. When the transmission of the image information of the original is continued, even if the receiving facsimile has an original waiting for transmission,
The image information of the transmission document which is urgently needed can be transmitted promptly, and the usability of the facsimile communication system can be improved.

Further, for example, as described in claim 4, when the transmission document presence / absence notifying means of the reception side facsimile device also notifies the transmission side facsimile device of the transmission start time of the transmission standby document, the transmission side facsimile device The transmission end time is calculated by the transmission time calculation means when the transmission of the transmission original is completed, and the transmission time calculation means is used even when the transmission stop means does not select the urgent transmission original by the urgent selection means. When the calculated transmission end time of is earlier than the transmission start time notified from the receiving side facsimile apparatus, if the transmission of the image information of the transmission original is continued, even if the transmission original is not an urgent original, the transmission original is When the transmission end time is earlier than the transmission start time of the receiving side facsimile device, the image information of the transmission original can be transmitted, and the transmission original can be efficiently transmitted. It can be sent to.

As a result, the usability of the facsimile communication system can be further improved.

Next, the operation will be described.

Facsimile communication system 1 of this embodiment
When a call is made from the sending side facsimile device 10 to the receiving side facsimile device 20, the receiving side facsimile device 20
If there is a document waiting to be sent to the receiving facsimile machine 20,
Notifies the transmitting side facsimile device 10 of that fact and the transmission time of the transmission standby document, and the transmitting side facsimile device 10
When receiving the notification that there is a transmission standby document and the transmission time from the reception side facsimile device 20, the transmission is continued / stopped based on the urgency of the transmission document.

The transmission canceling process and the transmission waiting document presence / absence notifying process will be described below with reference to the flowchart of FIG.

When transmitting an original, the operator of the facsimile apparatus 10 on the transmitting side sets the original to be transmitted on the reading section 13 and sets the destination telephone number, that is, the telephone number of the facsimile apparatus 20 on the receiving side, on the key of the operation display section 12. Input by operation.

When the transmission original is set in the reading unit 13 and the transmission destination telephone number is input (step S1), the transmission side facsimile device 10 prompts the user to select whether or not the transmission of the transmission original requires "urgent". The display is performed on the display of the operation display unit 12 (step S2), and when a selection operation for urgent transmission is performed, the selection result is displayed by the control unit 11.
Stored in the RAM or the like.

Next, the transmission side facsimile device 10 drives the reading unit 13 to read the image information of the transmission original set in the reading unit 13, decodes it by the encoding / decoding unit, and then sequentially. The storage unit 16 stores the data in the storage unit 16.
The data amount of the image information of the transmission original stored in is calculated and stored in the storage unit 16 in association with the image information of the transmission original (step S3).

When the transmission side facsimile apparatus 10 completes the storage of the image information of the transmission original in the storage section 16 and the calculation of the data amount, it calls the reception side facsimile apparatus 20 to call the reception side facsimile apparatus 20, When the receiving side facsimile device 20 responds, the facsimile communication is started (step S4).

On the other hand, when the facsimile machine 20 on the receiving side receives an incoming call from the facsimile machine 10 on the transmitting side, the facsimile machine 20 responds to the call, starts the facsimile communication procedure, and transmits it to the storage section 26 when the facsimile communication is not already in progress. It is checked whether or not the image information of the standby document is accumulated. When the image information of the document waiting to be transmitted is accumulated in the storage unit 26, the fact that there is the document waiting to be transmitted is stored in the storage unit 26 or the RAM of the control unit 21. The information of the transmission start time of the transmission waiting original document which has been transmitted is a facsimile communication signal, for example,
It is added to the NSF signal (non-standard function identification signal) shown in FIG.

When the transmission side facsimile apparatus 10 receives the facsimile signal to which the transmission standby document presence / absence information and the transmission start time information are added from the reception side facsimile apparatus 20 (step S5), the transmission side facsimile document is transmitted. The presence / absence information and the transmission start time information are taken out and it is checked whether or not there is a transmission standby document in the reception side facsimile device 20 (step S6).

When the receiving-side facsimile apparatus 20 has no transmission-waiting original document, the transmitting-side facsimile apparatus 10 performs a normal facsimile communication procedure to read the image information of the transmitting original document stored in the storage unit 16, and then the receiving-side facsimile apparatus. 20 (step S7).

After transmitting all the image information of the transmission original, the transmission side facsimile device 10 performs post-processing of a normal facsimile communication procedure and ends the facsimile transmission processing (step S8).

If there is a document waiting to be transmitted in step S6, the facsimile apparatus 10 on the transmission side checks whether or not "urgent" is selected in step S2, that is, whether the document to be transmitted is an urgent document (step S6). S9) If the transmission original is an urgent original, the normal facsimile communication procedure is performed to read the image information of the transmission original accumulated in the storage unit 16 and transmit it to the receiving side facsimile device 20 (step S7).

After transmitting all the image information of the transmission document, the transmission side facsimile device 10 performs post-processing of a normal facsimile communication procedure and ends the facsimile transmission processing (step S8).

In step S9, when the transmission original is not an urgent original, the time required for completing the transmission of all the transmission originals in the arithmetic unit 17 is calculated from the data amount of the transmission originals stored in the storage unit 16. , The transmission end time is calculated (step S10).

Next, the control unit 11 compares the transmission end time calculated by the calculation unit 17 with the transmission start time received from the receiving side facsimile device 20 (step S11),
It is checked whether the transmission end time of the transmission document is earlier than the transmission start time of the transmission standby document (step S1).
2).

At step S12, when the transmission end time is later than the transmission start time of the document waiting to be transmitted by the reception side facsimile apparatus 20, the transmission side facsimile apparatus 10 adds a transmission interruption notice to the facsimile signal and receives it. After transmitting to the facsimile device 20 (step S13) and disconnecting the line, the transmission process ends (step S1).
4).

That is, the transmitting side facsimile machine 10
At the time of transmission, as shown in FIG. 3, the receiving side facsimile device 20 makes a call, and when the receiving side facsimile device 20 receives an incoming call, it sends a CED signal (callee terminal identification signal) and then transmits. When the standby document (stored document) is stored in the storage unit 26, the fact that it is a document waiting to be transmitted and the transmission start time data (next transmission time data) of the document waiting to be transmitted are added to the NSF signal and the transmission side facsimile apparatus is added. Send to 10.

When the transmission side facsimile apparatus 10 obtains the existing data of the transmission waiting original and the transmission start time data from the received NSF signal, it calculates the transmission end time of the transmission original and compares it with the received transmission start time. When the transmission start time is earlier than the transmission end time, the transmission is stopped, the transmission interruption notification is transmitted to the reception side facsimile device 20, and then the DCN signal (disconnection command signal) is output to disconnect the line. .

At this time, the sending facsimile machine 10
Displays on the display of the operation display unit 12 that the transmission has been stopped.

Then, the transmitting side facsimile machine 10
When the transmission of the image information of the transmission original is stopped by the transmission canceling process, the retransmitting function causes the receiving side facsimile apparatus 20 which has stopped the transmission after a predetermined time has elapsed to recall the image information of the transmission original whose transmission has been stopped. Resend.

Therefore, the image information of the transmission original whose transmission has been stopped can be reliably transmitted by retransmission, and the usability of the facsimile communication system can be improved.

In step S12, the sending side facsimile device 10 determines that the receiving side facsimile device 20 precedes the sending start time of the sending standby document when the sending end time is earlier than the sending start time of the sending standby document. When it is determined that the transmission of the transmission document can be completed, the image information of the transmission document is read from the storage unit 16 and transmitted to the reception side facsimile device 20 by a normal transmission procedure (step S7).

When all the image information of the transmission original has been transmitted, the transmission side facsimile device 10 carries out post-processing of a normal facsimile communication procedure and ends the facsimile transmission processing (step S8).

As described above, according to the present embodiment, when the sending side facsimile device 10 calls the receiving side facsimile device 20, the receiving side facsimile device 20 checks the presence or absence of the sending waiting original document and checks the sending waiting original document. Presence or absence and the transmission start time are notified to the transmitting side facsimile device 10, and the transmitting side facsimile device 10 is notified by the receiving side facsimile device 2.
When the notification indicating that there is a transmission standby document is received from 0, the transmission of the image information of the transmission document is stopped, and the reception side facsimile device 20 is notified that the transmission of the image information of the transmission document is stopped.

Therefore, the transmitting side facsimile machine 10
When the facsimile machine 20 on the reception side has a transmission standby document, the transmission can be stopped, and the facsimile machine 20 on the reception side can reliably transmit the transmission standby document at the intended transmission time, and one after another. It is possible to prevent the image information of the received originals from being accumulated in the storage unit 26 one after another due to repeated incoming calls, and the image information of the transmission standby originals that have been transmitted is deleted from the storage unit 26 and stored. The part 26 can be effectively used.

Further, according to the present embodiment, in the transmission side facsimile apparatus 10, when the transmission request operation of the transmission original is performed, the operator operates the key of the operation display unit 12 so that the transmission original is "urgent". Is selected,
Even if a notification indicating that there is a transmission standby document is received from the reception side facsimile device 20, since the transmission of the image information of the transmission document is continued, it is possible that the reception side facsimile device 20 has a transmission standby document. Also, the image information of the transmission document which is urgently needed can be quickly transmitted, and the usability of the facsimile communication system can be improved.

Further, according to the present embodiment, the reception side facsimile device 20 notifies the transmission side facsimile device 10 of the transmission start time of the transmission standby document when the transmission standby document exists and the transmission standby document exists. Then, the transmission side facsimile device 10 calculates the transmission end time at which the transmission of the transmission document is completed, and even if the fact that the transmission document is urgent is not selected, the calculated transmission end time is the reception side facsimile device. If it is earlier than the transmission start time notified from 20, the transmission of the image information of the transmission original is continued. Therefore, even if the transmission original is not an urgent original, the transmission end time of the transmission original is the transmission start time of the receiving side facsimile device. When it is earlier, the image information of the transmission original can be transmitted, and the transmission original can be efficiently transmitted.

As a result, the usability of the facsimile communication system can be further improved.

Although the invention made by the present inventor has been specifically explained based on the preferred embodiments, the present invention is not limited to the above embodiments, and various modifications can be made without departing from the scope of the invention. Needless to say.

For example, in the above embodiment, the image information of the transmission original is stored in the storage unit 16 and the image information of the transmission standby original is stored in the storage unit 26, but the present invention is not limited to this. For example, even when the transmission standby document is set in the reading unit 23 and the transmission document is set in the reading unit 13, the same can be applied.

[0085]

The facsimile machine on the receiving side is notified that the transmission of the image information has been stopped.

Therefore, the receiving facsimile machine
When there is a transmission standby document, the incoming call can be stopped and the transmission standby document can be surely transmitted at the intended transmission time.

Further, when the image information of the transmission waiting original is stored in the image memory for storing the image information, the incoming call is repeated one after another and the image information of the received original is stored in the image memory one after another. Therefore, the image information of the transmission standby document that has been transmitted can be deleted from the image memory to effectively use the image memory.

In this case, as described in claim 2, when the transmission side facsimile device stops the transmission of the image information of the transmission original by the transmission stopping means, the retransmitting means stops the transmission after a predetermined time has elapsed. If the image information of the transmission document whose transmission has been stopped is retransmitted by re-calling to the facsimile device on the side, the image information of the transmission document whose transmission has been stopped can be reliably transmitted by retransmission, and the facsimile communication system The usability of can be improved.

Further, as described in claim 3, when the transmission side facsimile apparatus requests the transmission of the transmission document, the operator uses the urgent selection means to determine whether or not the transmission document is the transmission document which is urgent. Is selected and the transmission stop means selects the urgent transmission original by the urgent selection means, even if a notification indicating that there is a transmission standby original is received from the receiving facsimile machine, By continuing the transmission of the image information, the image information of the transmission document which is urgently needed can be promptly transmitted even when the reception side facsimile apparatus has the transmission standby document.
The usability of the facsimile communication system can be improved.

Further, as described in claim 4, when the transmission document presence / absence notifying means of the reception side facsimile device also notifies the transmission side facsimile device of the transmission start time of the transmission standby document, the transmission side facsimile device transmits the transmission start time. The transmission time calculation means calculates the transmission end time at which the transmission of the original is completed, and the transmission time calculation means calculates even if the transmission stop means does not select the urgent transmission original by the urgent selection means. When the transmission end time is earlier than the transmission start time notified from the receiving facsimile machine,
If you continue sending the image information of the transmission document, even if the transmission document is not an urgent document, if the transmission end time of the transmission document is earlier than the transmission start time of the receiving-side facsimile machine, the image information of the transmission document will be displayed. It can be transmitted, and the transmission original can be efficiently transmitted.

As a result, the usability of the facsimile communication system can be further improved.
