Abstract

PURPOSE:To eliminate undersired retransmission number of times by deciding a re-transmission number of times in response to type of a return signal from an opposite party when an automatic dialing function is in use to make line connection with the opposite party. CONSTITUTION:When a multiple address control section 5-1 reads a destination number sequentially when the time reaches a time stored in a communication management storage section 1 to control an automatic dialing section 7-1 thereby sending sequentially and automatically the destination. Then a called party reply is detected by a called party response detection section 7-2 and it is informed a communication management control section 5-2, which makes line connection. At the end of picture transmission, a normal flag is set to a flag column in the storage section 1 and stored. On the other hand, after the line connection, when a wrong phone call analysis section 5-3 does not send a FAX procedure signal within a prescribed time via a control section 7, it is discriminated to be a wrong phone call and a flag representing it is set. When the retrial indicates the similar result, a flag representing it is set and the result is stored without reproduction. Thus, number of times of connection is reduced.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is unnecessary by determining the number of retransmissions according to the type of signal returned from the other side when connecting a line to the other side using a facsimile machine, especially an automatic transmission function. The present invention relates to a facsimile device that minimizes retransmission.

[0002]

2. Description of the Related Art Conventionally, in the case of facsimile transmission of the same image to a plurality of destinations, whether the operator individually dials the telephone numbers of the destinations and is connected to the destination facsimile machine, or a person answers the telephone. After judging whether it was
The predetermined image signal was transmitted.

However, recently, a facsimile machine having an automatic transmission function or an automatic timer function, and a broadcast function has been used. When the designated time comes, the facsimile apparatus having the automatic transmission function automatically sends out the telephone number designated in advance and tries to establish a line connection with the other party. When the line is connected, the line may not be connected due to a temporary communication error or the like, so that it has been conventionally retransmitted up to 10 times, for example.

[0004]

In this case, if the line is not connected as in the case where the mode of repeatedly retransmitting is busy or in the case of a temporary communication failure, etc. If the call was made normally but the other party's telephone number is wrong, or if the line is shared with the telephone and facsimile lines and the line is set to receive calls, the above 10 times are repeated. However, the telephone charges may be undesirably increased, and a wrong call may be made at midnight, which may lead to social problems.

An object of the present invention is to solve the above-mentioned problems, and when the line is connected to the other party by using the automatic transmission function, the number of retransmissions is determined according to the type of the signal returned from the other party. This minimizes the number of unnecessary retransmissions.

[0006]

A facsimile apparatus according to the present invention comprises a number storage unit for storing a destination number, and a line connection unit for automatically reading a predetermined number from the number storage unit for line connection. , A called party response detecting section for detecting whether or not the line connecting section is connected by the line connecting section, and a line for transmitting an image signal when the called party response detecting section detects that the line connecting is made. And a communication management control unit that issues a command to the line connection unit and repeats line connection n times when the called party response detection unit detects that the line is not connected. The provided facsimile apparatus further includes a wrong call analyzing unit that determines that a FAX procedure signal is not detected for a predetermined time through the line from the time when the line is connected by the line connecting unit, and the wrong call analyzing unit. Therefore FAX procedure signal is characterized in that less than n times the line connection number by the communication management control unit if not detected even after the lapse of a predetermined time.

[0007]

In the case of the present invention, the number of reconnections can be reduced in case of a wrong telephone call.

FIG. 1 is a configuration of an embodiment of a facsimile apparatus having a broadcast function, FIG. 2 is an example of a flowchart for explaining the operation of the configuration shown in FIG. 1, and FIG. 3 is an example of a reception record list obtained by the configuration shown in FIG. FIG. 4 shows an example of flag contents used in the configuration shown in FIG.

In the figure, 1 is a communication management storage unit, 2 is an operation panel, 3 is a reading / transmitting unit, 4 is a receiving / recording unit, 5 is a main control unit,
5-1 is a broadcast control unit, 5-2 is a communication management control unit, 5-3
Is a wrong telephone analysis unit, 6 is a clock, 7 is an NCU, 7-1 is an automatic dial unit, 7-2 is a called party response detection unit, 8 is a transmission control unit, and 9 is a modem unit.

FIG. 1 shows the configuration of an embodiment of a facsimile apparatus having a broadcast function. In the figure, reference numeral 1 denotes a communication management storage unit, which is an image signal obtained by scanning a document by using the telephone number of the destination key-input from the operation panel 2 in the illustrated destination number field or by using the reading / transmitting unit 3. Are stored in the illustrated image memory or the like. Further, the trial number column in the communication management storage unit 1 is for recording the number of times of retransmitting repeatedly to the destination number of the other party. The flag column is used to set flags (shown in FIG. 4) representing respective states when the other party's predetermined transmission is normally completed, or when it is determined that a person has come to the other party.

In the figure, the main control section 5 is composed of a broadcast control section 5-1, a communication management control section 5-2 and a wrong telephone analysis section 5-3. When the time notified from the clock 6 reaches the time described in the transmission time column in the communication management storage unit 1, the broadcast control unit 5-1 sequentially reads out the destination numbers and NCU.
(Line control unit) The automatic dial unit 7-1 in the unit 7 is controlled to automatically send the destination numbers to the line in sequence. And
When there is a called party response, the illustrated called party response detecting section 7
-2 detects the callee response signal, and notifies the communication management control unit 5-2 in the main control unit 5 to that effect. This allows
The line connection has been made.

Next, when the communication management control unit 5-2 receives a FAX procedure signal, for example, a signal of 300 bps, through the NCU 7 after the line connection is made, the facsimile machine concerned is normally operated by the facsimile machine of the other party. Then, the image signal stored in the image memory in the communication management storage unit 1 is read out and sent to the line via the transmission control unit 8, the modem unit 9 and the NCU 7. As a result, the image signals are sequentially transmitted to the facsimile device having the destination number.
When the transmission of all image signals has been completed, a flag indicating normal termination is set and stored in the flag column in the communication management storage unit 1. Then, similarly, the next destination number is also performed.

On the other hand, after the line connection is established, the wrong call analysis unit 5-3 sends the FAX procedure signal (300) via the NCU 7.
If a (bps signal) is not received within 40 seconds, for example, it is determined that a wrong call or a person has answered the other party, and a flag indicating a wrong call etc. in the flag field in the communication management storage unit 1. Set up. Then, if it is determined that the call is a wrong phone or the like even if the same destination number is retransmitted again, it is no longer retransmitted and a flag to that effect is set in the flag column in the communication management storage unit 1. Remember.

In this way, when the time of transmission is reached,
After the destination number is read out and the line connection is automatically performed, the image signal is automatically transmitted to the destination facsimile machine via the line. The transmitted result is stored in the flag column in the communication management storage unit 1 described above, and can be read out from the illustrated reception recording unit 4 in a form as shown in FIG.

FIG. 2 shows a state in which it is detected whether or not the call is a wrong phone. As described above, this is after the NCU 7 shown in FIG.
-3 is judged to be a wrong telephone when the FAX procedure signal is not detected within, for example, 40 seconds later. In the case of YES, the process below the state is executed. In the case of NO, the process below the state is executed.

The figure shows a state in which the wrong telephone flag is turned on (set). The figure shows a state in which the bit of the wrong call is set in the communication content column in the communication management record in the communication management storage unit 1 shown in FIG.

The figure shows a state in which it is detected whether or not the user is busy. This is determined by whether or not the called party response detection unit 7-2 shown in FIG. 1 detects the called party response signal. YES
If, execute the state. If no, execute state.

The figure shows a state in which the busy bit is set in the communication content column in the communication management record, and the number of trials in the trial number column (the number of attempts to connect to the other party) is incremented by 1.

The figure shows a state in which a bit indicating good or abnormal communication is set in the communication content column in the communication management record and the number of trials is incremented by one. The figure shows a state in which it is determined whether or not the transmission has been completed up to the last page. If YES, the process ends (END). In the case of NO, the states below are executed.

The figure shows a state in which it is judged whether or not the telephone number of the wrong telephone number is the same as the telephone number of the telephone number flagged in the above state. In the case of YES, the following states are executed. In the case of NO, the state (10) and below are executed.

In the figure, the bit for wrong call is set and the number of trials in the trial number column is set to n. As a result, the number of trials n, which is in a state of not forcibly retransmitting when a wrong telephone is connected, is set to, for example, 10 times.

In the figure, (10) shows a state of detecting whether or not the user is busy. If YES, state (11) is executed. NO
In the case of, the state (12) is executed. In the figure, (11) shows a state in which the busy bit is set and the trial number is incremented by one.

In the figure, (12) shows a state in which a good bit is set and the trial number is incremented by one. In the figure, (13) shows a state where it is determined whether or not the transmission up to the last page is completed. YES
In case of, it ends (END). If NO, state (1
Execute 4).

In the figure, (14) shows a state in which it is judged whether or not the number of trials is equal to n. If YES, the process ends (END). In the case of NO, the state and the following steps are repeated.
At this time, if the wrong telephone is connected, the number of trials is set to n depending on the state, so that the result is YES and the process ends.

FIG. 3 shows an example of the reception record list. The "item" on the left end of the figure shows the number of telephone numbers (destination numbers) of the communication destinations input from the operation panel 2 or the number of retransmitted communication destinations arranged in the order of input or retransmission.

In the figure, "file" indicates the file name of the transmitted image signal. In the figure, "communication destination" indicates the telephone number of the other party to which the image signal is transmitted. In the figure, "communication start time" indicates the time when the transmission of the image signal is started.

In the figure, "required time" indicates the time required to transmit the image signal. In the figure, the "communication number" indicates the number of completed transmissions. When the entire original is transmitted at one time, the number of transmitted sheets is shown, and when the transmission is stopped midway due to some communication failure or the like, the number of sheets already transmitted is described. Then, at the next opportunity, the remaining number of sheets is transmitted and the number of sheets retransmitted is added.

In the figure, "communication mode" indicates a communication system of a facsimile machine for communication. The illustrated "G3 Broadcast" is the so-called G
It indicates that the data is transmitted by the three methods and the broadcast function. In the figure, "communication content" indicates the state of communication as described with reference to FIG. For example, “good” in the figure indicates that the transmission of the image signal is normally completed. On the other hand, the “wrong phone” shown in the figure is recorded when the wrong phone status occurs, and when the wrong phone status occurs at the communication destination, it is no longer resent. Further, the "#" mark at the right end of the communication content column indicates that the time is designated. That is, the image signal is transmitted at the time designated by the broadcast controller 5-1 shown in FIG.

FIG. 4 shows the communication management storage unit 1 shown in FIG.
The example of a state for storing the illustrated communication content is shown. When the called party response signal is not detected after calling, "00" is stored in (a) in the figure.

After the calling, the above-mentioned wrong telephone is detected,
When the flag is set (shown in FIG. 2), “01” is stored in (a) in the figure. B = in the figure (b) after calling
When it becomes A (when all the communication numbers have been normally transmitted), “10” is stored in (a) in the figure. Here, "B" in (b) in the figure indicates the number of sheets actually communicated, and "A" indicates the total number of sheets to be communicated. The A and B are composed of 1 byte.

When A <B in the figure (b) after the call is made (when a communication error occurs in which all the sheets are not communicated), "11" is stored in the figure (a). It In the figure, (c) shows the operating state of the broadcast function shown at the right end of the communication content column in FIG. “1” indicates an operating state, and “0” indicates a non-operating state.
