Description

DETAILED DESCRIPTION OF THE INVENTION (Objects stated in Section 5) (Field of Application in Business B) The present invention relates to an improvement of a fuction machine having an automatic re-call function.

(Prior art) Conventionally, when transmitting a document, the image of the document to be sent is stored in an image signal memory, and then a call operation is performed, and after the line is connected, it is necessary to confirm that the called party is a facsimile device, etc. After checking the facsimile communication control procedure (CCITTV Notice T.30, etc.), when a call is made on the facsimile device that transmits the image of the original in the ffi memory, If the line is not connected within a certain period of time due to a child being in use, ■If the called party disconnects the line after the line is connected without responding according to the facsimile control procedure, ■If the calling party disconnects the line after the line has been connected, When the calling party disconnects the line, under any of the following conditions, there is a configuration in which an automatic re-calling operation is performed at fixed time intervals after a fixed period of time as a line connection error.

According to this device, even if the facsimile machine on the calling side is in use, if it returns to the receiving standby state during the subsequent re-calling operation, a normal line connection will be established and the message will be sent reliably. be able to.

However, if the called party is a regular subscriber telephone and not a facsimile machine, a certain number of useless re-call operations are performed, and the called party must also answer the incoming call in a corresponding manner to the number of re-calls. It turns out. Furthermore, on the B/L call side, communication charges will increase due to a certain number of double call operations. This problem can be solved to some extent by reducing the number of re-calls, but if the other party is using a facsimile machine and it is in use, the re-call operation will be quickly given up. There is a problem that the possibility of connection to the destination is reduced.

(Problem to be Solved by the Invention) As mentioned above, in conventional facsimile machines that automatically re-call a certain number of times, if the line is not connected correctly, the facsimile machine automatically re-calls a certain number of times at certain time intervals. Therefore, if the receiving party is a general subscriber phone, it is necessary to perform a fixed number of young call operations, making it troublesome to answer the call. There is a problem in that communication charges due to call operations increase.

The present invention provides a facsimile machine that eliminates the above-mentioned problems, prevents an increase in missed calls when the other party is not a facsimile machine, and can roughly reduce unnecessary responses on the called side. The purpose is to

[Structure of the Invention] (Means for Solving the Problems) Masaaki Moto has developed an unconnected number counter that counts the number of times that a J3 line connection is not possible within a certain period of time, and a
It is equipped with a connected number counter that counts the number of times facsimile communication could not be started normally after connecting to the other party's line. This is configured by varying the number of times when line connection is not possible and the number of times when facsimile communication cannot be normally started after line connection with the communication partner.

(Function) In the present invention, if a line connection cannot be detected even after a certain period of time has passed after a call operation, the line is disconnected and the unconnected number counter is updated, and a line connection is detected after the call operation. If the line is disconnected after the call has been made, the connected number counter is updated, and when the count value of the unconnected number counter or the connected number counter reaches a predetermined number of times, an automatic re-call operation is performed. stop. Therefore, if you set the count value of the connected number counter = 1 and the count value of the unconnected number counter = 3 as the conditions for stopping the automatic re-call operation, for example, the second call when the other party is not a facsimile machine. No needless re-calling operation will be performed thereafter. However, if the communication partner is a facsimile machine, the automatic calling operation is performed up to three times, increasing the possibility that the message will be sent.

3 is an encoding unit that encodes the read image signal; 3 is a modulation unit that modulates the coded image code 7 encoded by the code 1 Hi unit 2;
4 is a network control unit (which sends the signal modulated by the modulation unit 3 to the line 11 and receives the signal arriving from the line 11;
NCU>, 5 is a control unit, 6 is a memory for storing the encoded image signal -Ff1, 7 is a demodulation unit that converts the signal input from the NCU 4 into digital data, and 8 is demodulated by the demodulation unit 7. 9 is a recording unit that records and outputs the image signal decoded by the decoding unit 8 on recording paper; 10 is a key for the operator to input a telephone number, transmission instructions, etc.; It is a one-person team.

Here, the control unit 3 is equipped with, for example, a microcomputer, and performs facsimile communication control, reading control, recording control, etc., and also counts the number of times that line connection is impossible within a certain period of time. Number of times counter 5
1, and a connected number counter 52 which counts the number of times facsimile communication could not be started normally after the line connection with the communication partner.

The NCU 4 includes an @ line connection detection stage 41 that detects that the line is connected after sending out a dial pulse.

The operation of this embodiment will be explained below according to the operation flow shown in FIGS. 2 and 3.

First, in the standstill state, the system monitors the arrival of a call from the line 11 or the start of a calling operation based on an instruction from an operator, etc., and when an incoming call is detected, a normal call receiving operation is performed (steps 201 and 202). When the reading operation is started in response to an instruction from an operator, reading of the original is started by the reading unit 1 (step 203), and the pictures of the read original are encoded by the encoding unit 2 and stored in the memory 6. Thereafter, a calling operation is performed from the NCU 4 (step 2o4).

Therefore, if the line connection is established by the line connection detection step 41 and it is confirmed that the other party is using a facsimile, normal document transmission processing is performed (steps 205 and 20).
6.207).

For example, CCITT determines whether the other party is a fax machine or not.
Recommendation T. 3 0. The determination can be made based on whether or not the GC Yo80 1 S{i number (initial identification signal) etc. can be received. When the DIS signal can be received, it is determined that the communication partner is a facsimile machine.

If it cannot be confirmed in step 206 that the communication destination is a facsimile, the process continues in step 20 until a certain period of time set in a timer (not shown) has elapsed.
6,208.209 is looped (loop a). Then, when line disconnection is detected in this lube a, step 2
From step 08 to step 210, the connected number counter 52 is updated, and in step 211, it is checked whether the count 1 value of the already connected number counter 52 has reached the preset upper limit. If not, step 210 is performed. The process moves to step 204, and the process moves to a re-calling operation. However, if the count value of the connected number counter has reached the upper limit value in step 211,
It is determined that the other party is not a facsimile user, and in step 301, communication abnormality processing is performed, for example, a message indicating that the document could not be sent normally is outputted from the recording unit 9.

On the other hand, after the calling operation in step 204, steps 205 and 302 are looped until the line is connected (loop b). Therefore, when a certain period of time has elapsed in step 302 of Lube b, it is determined that the line cannot be connected due to the other party's line being in use, etc., the process moves from step 302 to step 303, the line is disconnected, and the unconnected number counter 51
Update. If the count 1 value of the unconnected number counter 51 has not reached the preset upper limit, the process moves to the calling operation in step 204, and a re-calling operation is performed (steps 304, 305). However, if the count value of the unconnected number counter 51 has reached the upper limit value in step 305, it is determined that there is little possibility of connection even if the call is made again, and the process moves to step 301. This occurs, for example, when the other party is not present and the other party's facsimile machine is not automatically designated for reception.

After the line is connected to the other party in this way, is it determined that the other party is not a facsimile machine? In this case, the number of connections counter is updated, and when the counter 1 value reaches a predetermined upper limit, the automatic re-calling operation is stopped, so the upper Wi value in this case is reduced. If you leave it there, the other party will not know what to do. This reduces unnecessary re-calls to places other than the Kushimi device, prevents unnecessary increases in communication charges, and reduces unnecessary responses on the called side. Furthermore, if there is a possibility of an erroneous connection due to exchange n, by setting the upper limit value of the unconnected number counter to "2" or more, it is possible to resolve the situation where a message is not sent due to an erroneous connection.

Note that in the above embodiment, the encoded image signal is stored in the memory.
Although the facsimile apparatus transmits data after sending an I, it can be similarly applied to a facsimile machine that does not have such a storage function.

[Effect of the invention] In the J; sea urchin described above, in the present invention, after the Sanskrit operation,
If a line connection cannot be detected after a certain period of time has passed, the line is disconnected and the unconnected count J counter is updated. Also, if the line is disconnected after a line connection is detected after 11 call operations. updates the connected number counter and sets the count 1 of the above unconnected number counter or connected number counter
・Since the automatic re-calling operation is configured to stop when the value reaches a predetermined number of times, the automatic re-calling operation can be stopped by setting, for example, the number of connected times counter l・value = 1, If the number of unconnected calls/Kunta's counter is set to 1/value = 3, wasteful re-calling operations will not be performed from the second time onwards when the communication destination is not a facsimile machine. However, if the communication partner is a facsimile machine, the initial call operation is performed up to three times, increasing the possibility that the message will be sent. Therefore,
Is the other party fu? It is possible to prevent an increase in communication charges in the case of a non-Kushimiri device, and to reduce unnecessary responses on the called side. Furthermore, when the line is not connected, such as when the other party is in use, re-calling can be performed in the same way as before.
