DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to facsimile communication.
In particular, the present invention relates to a facsimile apparatus that transmits data to a receiving facsimile apparatus again when transmission of a message to the receiving facsimile apparatus is impossible.

[0002]

2. Description of the Related Art A conventional facsimile apparatus of this type will be described with reference to a facsimile storage / broadcast apparatus .

[0003] In recent years, as the use of facsimile communication has increased, facsimile storage and broadcasting devices have been increasingly used.

A conventional facsimile storage / broadcasting device of this type temporarily stores a broadcast message received from a terminal and performs a broadcast process in accordance with the control contents of the message. At the time of transmission, if the terminal device of the other party enters an abnormal state due to power off, out of recording paper, busy or line error, etc., it is judged that transmission has failed and retransmission processing is repeated multiple times. I have.

[0005] In the retransmission process, the interval until a recall is always constant. That is, retransmission is started after waiting for a predetermined interval (time).

[0006]

[0005] It is pointed out that the conventional F
The facsimile machine has a recovery time from the cause of transmission failure,
Despite the length of the cause, the interval between recalls was always set constant.

For this reason, retransmission is performed before recovery from the cause of the transmission failure, thereby causing a transmission failure again. For example, a problem unfavorable in line utilization efficiency has occurred.

In addition, the interval until a re-call is always constant.
Therefore, re-calls are made every time a certain time elapses.
Further increase the number of recalls to the same terminal
There was a problem. On the other hand, it is necessary to prevent the number of recalls from increasing.
Therefore, if you limit the number of recalls, the
A problem that the operation is completed.

[0009] Therefore, the present invention provides a method for the same destination terminal.
Recalling count consideration and as can be determined finely the call interval of, improve and unsent split number utilization efficiency that
It is an object of the present invention to provide a facsimile apparatus capable of reducing the number of cases.

[0010]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention transmits image information to a designated destination terminal and, when transmission to the destination terminal is impossible, makes a plurality of repetitions. a transmission processing unit that performs transmission processing, transmission impossible der

By the above structure [action], can be recalling at <br/> call intervals in consideration of recalling number of times, as a result, recalling times
By changing the call interval according to the number, the busy increase can be prevented.
This makes it possible to use the line efficiently.

Also, since the call interval taking into account the number of recalls is preset, the call interval is carefully determined.
Thus , the above-described effects can be obtained with a very simple configuration.

[0013]

An embodiment of the present invention will be described with reference to the drawings. This embodiment is also an example of a facsimile machine as in the prior art.
A facsimile storage and broadcasting device will be described as an example.

FIG. 1 is a schematic block diagram showing an embodiment of a broadcast communication system including a facsimile apparatus according to the present invention. In FIG. 1, FAX1, FAX2,. S may be a reception-only device.), S is an exchange connected to each of the facsimile terminal devices FAX1 to FAXn via a facsimile communication line, and M is a plurality of reception and transmission lines (FIG. Is a facsimile apparatus of the present invention connected via two lines. Note that MIN is a connection end of the reception line, and Mout is a connection end of the transmission line.

In this embodiment, a known broadcast instruction mark sheet (although an OCR sheet or the like can also be used) as input means of control information for controlling broadcast communication.
Is used.

As shown in FIG. 1, a broadcast apparatus M includes a facsimile reception control unit (increases or decreases according to the number of lines) 1 for controlling facsimile reception and a reception channel control unit 2 for controlling the entire reception channel. A message reception management unit 3 for receiving and managing the broadcast message; a message storage unit 4 for storing the content of the broadcast message; and a message management for storing and managing information other than the content of the broadcast message, for example, the reception date and time. An information storage unit 5;
A message delivery management unit 6 for extracting a broadcast message when transmission is required; a transmission channel control unit 7 for controlling the entire transmission channel; and a facsimile transmission control unit 8 for controlling transmission of the broadcast message to a destination. A mark sheet recognizing unit 9 for recognizing control information necessary for broadcast from information on a broadcast instruction mark sheet input together with a broadcast message, and terminal information for storing terminal information (described later) in advance. Storage unit 1
In addition to 0, the calling interval (time) according to the situation (failure cause) at the time of broadcast transmission failure and the number of recalls in advance
And a call pattern number (which is stored in advance in the terminal information storage unit 10 as described later) when broadcast transmission fails from the call interval storage unit 11. ), A call interval control unit 12 for extracting a call interval at the time of the transmission failure determined by the failure status and the number of recalls.

As shown in FIG. 2, the terminal information storage unit 10 is composed of a plurality of storage units 10a, 10b,... Each of these storage units is configured to be searchable.

Each of the storage units 10a, 10b,..., 10n includes a terminal number (each FAX _{1 to} FAX _n number) storage unit, a terminal name (distribution destination name, a management unit name, etc.) storage unit, a telephone number storage unit, and a call. A pattern number storage unit and the like are provided, and each of these storage units stores and manages destination information for broadcast communication separately.

The counterpart ground information of each of the storage units 10a, 10b... 10n is taken into the message reception management unit 3, the message distribution management unit 6, and the mark sheet recognition unit 9 as required.

In particular, the calling pattern number (counterparty information) in the calling pattern number storage unit is taken into the calling interval control unit 12 as described later.

As shown in FIG. 3, the call interval storage unit 11 stores the same number of storage units 11a and 11b in correspondence with each call pattern number stored in the terminal information storage unit 10.
.. 11n are arranged in series, and each of these storage units can be sequentially searched.

Each of the storage units 11a, 11b,... 11n is appropriately determined according to the number of re-calls and the situation at the time of failure in broadcast transmission (for example, classified into busy, line error, communication error, etc.). call interval N ₁₁ to N _nm is previously stored for each calling pattern number.

The calling interval can be further finely modified by subdividing the number of recalls and the failure status. This enables more efficient broadcast communication.

Next, the operation of the broadcasting device M having the above configuration will be described. If a broadcast command mark sheet and a broadcast message are set in FAX ₁ shown in FIG. 1 and a transmission operation is performed, these messages are transmitted via the exchange S in accordance with a general-purpose facsimile transmission procedure. The image is received by the unit 1 as image information.

The received image information is input to the message storage unit 4 and the message management information storage unit 5 via the reception channel control unit 2 and the message reception management unit 3 line by line, and at the same time, the mark sheet recognition unit 9 Is input to

Based on the input data input to the mark sheet recognizing section 9, the recognizing section 9 detects the presence or absence of a mark, that is, the presence or absence of control information necessary for broadcast communication. When the presence of the control information is confirmed, the terminal number information of the destination is extracted from the control information, and the terminal number information is compared with each information (terminal number) in the terminal information storage unit 10.

As a result of the comparison, when it is determined that the two information do not match, information indicating that the registration has been completed is returned to the transmitting side, and when it is confirmed that they match, the broadcast communication is performed. The possible information is output from the mark sheet recognition unit 9 to the facsimile reception control unit 1.

The facsimile reception control unit 1 having received the broadcast enabling information transfers the broadcast message to the message reception management unit 3 via the reception channel control unit 2. Then, the management unit 3 accumulates the content of the broadcast message in the message storage unit 4 and, at the same time, accumulates information such as the reception date and time other than the message content in the message management information storage unit 5. Here, a series of reception operations ends.

When transmission is required, the message distribution management unit 6 retrieves terminal information (terminal number, terminal name, telephone number, etc.) from the terminal information storage unit 10 and sends it to the transmission channel control unit 7. Via the facsimile transmission control unit 8 Hereinafter, a broadcast message is transmitted from the transmission control unit 8 to the destination (FAX _{2 to} FAX _n ) sequentially or simultaneously according to a transmission procedure based on the broadcast control.

On the other hand, when the transmission fails, the transmission control unit 8 notifies the message distribution management unit 6 via the transmission channel control unit 7 of the transmission failure status (busy, line abnormality, communication error, etc.).

The message distribution management unit 6 further notifies the transmission interval control unit 12 of the transmission failure status. The calling interval control unit 12, which has received the transmission failure state, extracts the calling pattern number of the other party from the terminal information storage unit 10, and stores the calling pattern number corresponding to the calling pattern number in the storage unit of the calling interval storage unit 11 ( for example, from the storage unit 11a), the pull out the call interval (e.g. N ₂₂₎ determined by the transmission failure situation and the recalling count, during the call interval (time), reserves the transmission.

Thereafter, the calling interval control unit 12 supplies a re-calling start signal to the message distribution management unit 6. Thereafter, the broadcast message is transmitted again to the destination according to the above procedure.

Although the present embodiment has described the communication between the facsimile storage / broadcasting apparatus and the general facsimile apparatus, it goes without saying that the present invention can be applied to the communication between general facsimile apparatuses.

[0034]

As is apparent from the above description, according to the present invention, when performing the re-call processing, the destination where transmission was impossible is performed.
The number of retransmission processes to the same terminal as the terminal is determined, and this
By performing a retransmission process to the destination terminal based on the call interval set in advance corresponding to the number, Runode can be recalling the calling interval in consideration the number of times recalling,
