Abstract

PURPOSE:To minimize the unnecessary number of times of retransmission by deciding the number of times of retransmission in response to kinds of signals returned from an opposite party in using an automatic calling function and connecting the circuit to the opposite party. CONSTITUTION:When a communication management control section 5-2 receives an FAX procedure signal, e.g., a 300bps signal via a line control section (NCU) after line connection, the corresponding facsimile equipment discriminates that the equipment is connected normally to the facsimile equipment of the opposite party, a picture signal stored in a picture memory in a communication management storage section 1 is read and transmitted to a line via a transmission control section 8, an MODEM section 9 and the NCU7. On the other hand, when a wrong call analysis section 5-3 does not receive the FAX procedure signal (300bps signal) via the NCU7 within, e.g., 40sec after the line connection, it is discriminated as a wrong call or the reply by the opposite party, a flag representing the state of wrong call is set to a flag column in the communication management storage section 1. When it is discriminated as a wrong call or the like after the same destination number is transmitted again, no signal is transmitted again at all.

Description

Detailed Description of the Invention (Technical Field of the Invention) The present invention relates to a facsimile machine, particularly when an automatic dialing function is used to establish a line connection with the other party, the number of retransmissions is determined according to the type of signal returned from the other party. The present invention relates to a facsimile machine that minimizes unnecessary retransmissions by determining the number of retransmissions.

(Technical background and problems) Conventionally, when transmitting the same image to multiple recipients by facsimile, the operator dialed the recipient's phone number individually and checked whether the recipient's facsimile machine was connected or if the telephone After determining whether someone was present, a predetermined image signal was sent.

However, recently, automatic call function or automatic timer function,
Furthermore, facsimile machines equipped with broadcast functions and the like have come into use. A facsimile machine equipped with the automatic dialing function automatically sends out a previously designated telephone number at a designated time and attempts to establish a line connection with the other party. Conventionally, for example, 10
Until then, the data had been retransmitted repeatedly.

In this case, it is sufficient if the repeated retransmission is due to the line not being connected, such as when the line is busy or due to a temporary communication failure, but for example, even though the line connection was established normally, the other party's If you enter the wrong phone number,
Or, if the telephone and facsimile lines are shared and the telephone reception status has been interrupted, the above-mentioned retransmission will be repeated 10 times, unnecessarily increasing telephone charges, or making a mistake in the middle of the night. This may lead to phone calls and may lead to social problems.

(Object and Structure of the Invention) An object of the present invention is to solve the above-mentioned problems. By determining the number of retransmissions, the number of unnecessary retransmissions can be minimized. Therefore, the facsimile apparatus of the present invention includes a number storage unit that stores the destination number, a transmission start time storage unit that stores the time to start transmission, an image memory that stores the read image signal, and the transmission start time. a broadcast control section that reads out the transmission time stored in the storage section and compares it with a clock to detect that a predetermined time has arrived; a line connection unit that reads out a predetermined destination number from and automatically establishes a line connection; a called party response detection unit that detects whether or not a line connection has been made by the line connection unit; a transmission control unit that transmits an image signal stored in the image memory via the line when the response detection unit detects that the line has been connected; and a transmission control unit that connects the line by the called party response detection unit. communication management control that issues a command to the line connection unit to repeat the line connection n times when it is detected that the line connection is not completed or when the transmission of all predetermined image signals is not completed while the line is connected by the line connection unit; In a facsimile machine equipped with
The wrong call analysis unit determines whether a procedure signal is not detected for a predetermined period of time, and if the wrong call analysis unit does not detect a FAX procedure signal even after a predetermined period of time, it issues a command to the line connection unit to disconnect the line. The present invention is characterized in that the number of times the connection is repeated and the number of times the connection is repeated is smaller than the number of times repeated by the communication management and control section.

(Example of the invention) The present invention will be described in detail below with reference to the drawings.

Figure 2 shows an example of the configuration of a facsimile machine equipped with a rerouting function. 1 in the figure is the communication management storage unit, and the operation panel 2
This is for storing the telephone number of the other party entered manually in the illustrated destination number field, or the image signal obtained by scanning the document using the reading and transmitting section 3 in the illustrated image memory, etc. be. In addition, the several types of attempts in the communication management storage unit 1 are used to record the number of repeated retransmissions to the destination number of the destination mentioned above. This is to set a flag (shown in FIG. 4) indicating the respective status when the process ends normally, or when it is determined that someone is present at the other end.

In the figure, the main control unit 5 includes a communication control unit 5-1 and a communication management control unit 5.
-2 and a wrong call analysis section 5-3.

When the time notified from the clock 6 reaches the time written 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 sends them to the NCU (line control unit).
The automatic dialing unit 7-1 in the mobile terminal 7 is controlled to automatically sequentially send out the destination numbers to the lines. When there is a called party response, the illustrated called party response detection unit 7-2 detects the called party response signal and sends a message to that effect to the communication management control unit 5-2 in the main control unit 5. to notify. This means that a line connection has been established.

Next, after the line connection is made, the communication management control unit 5-2
is a FAX procedure signal, for example 3QObp, via NCU7.
When the signal s is received, it is determined that the facsimile device has been successfully connected to the other party's facsimile device, and the transmission control section 8 reads out the image signal stored in the image memory in the communication management storage section 1. Modem section 9 and NCU
7 to the line. As a result, image letters are sequentially transmitted to the facsimile machines of the destination numbers. When the transmission of all image signals is completed, a flag indicating normal completion is set and stored in the flag column in the communication management storage unit 1. Then, do the same for the next destination number.

On the other hand, if the wrong call analysis unit 5-3 does not receive the FAX procedure signal (30Qbps signal) via the NCU 7 within, for example, 40 seconds after the line is connected, it is determined that there is a wrong call or there is no one at the other end. It is determined that the call has been received, and a flag is set in the flag column in the communication management storage unit 1 to indicate that the call is a wrong call or the like. If you resend the same destination number again and it is determined that it is a wrong call, etc.,
Instead of retransmitting, a flag to that effect is set in the flag column in the communication management storage section 1 and recorded.

In this way, when the call time arrives, the destination number is read out and line connection is automatically established, and then the image signal is automatically transmitted to the destination facsimile machine via the line. Ru. The transmitted result is stored in the flag column in the communication management storage section 1 described above, and can be read out from the illustrated reception recording section 4 as shown in FIG. 3, which will be described later, if necessary.

In FIG. 2, ■ indicates a state in which it is detected whether or not it is a mistaken call. As mentioned above, this is shown in Figure 1.
