Abstract

PURPOSE:To upgrade the probability of immediate communication with the opposite by giving, in case the communication with the opposite ends in failure due to a line error, another telephone number designating the same opposite as the last to an automatic dialing function to actuate it after the lapse of a prescribed time and letting the function perform redialing action. CONSTITUTION:A decision means 1 decides whether the communication with the opposite fails due to a line error after the line connection or not, and supplies the result of the decision to a telephone number conversion means 12. The means 12, in case the communication with the opposite ends in failure, gives the automatic dialing function 4 another telephone number designating the same opposite as the last. A redial control means 2, after the lapse of a prescribed time, actuates the function 4 to which another telephone number is given to let it perform a redialing action. As a result, in case a line connection line error occurrs and the communication fails, a redialing action can be perform by using another line, and thus the opposite can be immediately connected to execute the communication.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a facsimile machine with an auto-dial transmission function and a redial function, and particularly relates to a back-dial process in the event of a line error.

(Prior Art) Conventionally, this type of facsimile machine communicated using only one line, such as the NT1 line, but NCC (
With the entry of new Type 1 telecommunications carriers, it has become possible to select and use the lines of these new carriers. However, with conventional facsimile machines, if the transmission fails due to a line error after dialing using auto-dial, the redial function works and dialing is performed again using the same telephone number, that is, the same line network. However, there was a high probability that a line error would occur again, and it was difficult to communicate with the other party. However, if it is possible to use another line to dial the other party when redialing due to a line error, it is possible to avoid a line with many errors, increasing the probability of being able to communicate with the other party immediately.

However, at present, conventional facsimile machines do not have a function of redialing using a separate line.

(Problems to be Solved by the Invention) As mentioned above, in conventional facsimile machines, if transmission fails due to a line error after the line is connected by auto-dial, the same line is used again to redial.
The disadvantage was that it was impossible to avoid lines with many errors, and it was difficult to communicate with the other party, or it became impossible to communicate at all. SUMMARY OF THE INVENTION Therefore, the present invention aims to eliminate the above-mentioned drawbacks and to provide a facsimile device that can redial using another line network when transmission fails due to a line error after line connection. .

[Structure of the Invention] (Means for Solving the Problems) The present invention provides an auto-dial function that sends a dial corresponding to a specified telephone number, and a system that provides automatic dialing when communication with the other party fails after sending a dial. In a facsimile machine equipped with a redial function for re-dialing a destination after a predetermined period of time, a determination means for determining whether or not communication with the destination has failed due to a line error after line connection, and said line error. telephone number conversion means for giving the auto-dial function a different telephone number specifying the same destination as the previous time when communication with the other party fails; The present invention is configured to include a redial control means that is activated after a predetermined period of time to perform a redial operation.

(Operation) In the facsimile apparatus of the present invention, the determining means determines whether communication with the other party has failed due to a line error after the line is connected, and provides the result to the telephone number converting means. If communication with the other party fails due to the line error, the telephone number conversion means provides the auto dial function with another telephone number specifying the same party as the previous one. After a predetermined period of time, the redial control means activates an auto-dial function to which the different telephone number is given and performs a redial operation.

(Example) An example of the present invention will be described below with reference to the drawings. 1st
The figure is a block diagram showing an embodiment of a facsimile apparatus of the present invention. 1 is a main control unit that controls the entire device such as dialing, data transmission/reception, and redial control; in particular, a telephone number readout control unit 1 that controls reading out telephone numbers;
1 and a telephone number conversion section 1 that controls giving an additional telephone number to the auto dial sending section 4 in order to convert the sending dial.
It has 2. 2 is a communication control unit that performs modulation/demodulation, code/decoding processing, etc. of transmitted and received data; 3 is a network control unit (NCU) that performs line capture/release control; 4 is an auto-dial sending unit that automatically sends dials on the line; 5 1 is a telephone number storage unit that holds the telephone number of the communication partner, 6 is an input unit for inputting the other party's one-touch dial information, etc., 7 is a document reading unit that reads the transmitted manuscript, and 8 is a printout of received data, etc. However, the telephone number readout control unit 11
The telephone number converter 12 is one routine of a program running within the controller 1.

Next, the operation of this embodiment will be explained. When transmitting the original set in the original reading section 7, the operator inputs the input section 6.
Dial information such as one-touch dialing from the main control unit 1
Enter. The main control section 1 passes the input dial information to the telephone number readout control section 11. The telephone number reading control section 11 reads out the telephone number corresponding to the input dial information from the telephone number storage section 5 and provides it to the auto-dial sending section 4 . The auto-dial sending section 4 generates a dial corresponding to the given telephone number, and the communication control section 2 sends this dial onto the line via the NCU 3. After the line is connected in this way, if no line error occurs, the image data read by the document reading section 7 is transmitted to the other party by the communication control section 2. Here, line connection @
Afterwards, when a line error occurs, the main control section 1 detects this, releases the line once, and then begins a redial operation. If the main control section 1 determines that this device can use another line, the telephone number conversion section 12 sends the additional telephone number to the auto-dial transmission section 4. When redialing, the auto-dial sending unit 4 generates a dial corresponding to the telephone number obtained by adding this additional telephone number to the telephone number dialed immediately before, and the communication control unit 2 transmits the dial on the line via the NCU 3. Send to. This other phone number is a phone number that connects this device to the same destination using, for example, another line network other than the NTT line network, so when redialing, a different line network is used to confirm the previous line error. This device will be connected to the same destination where the error occurred. Note that after the auto-dial sending section 4 sends out the dial, if the line is not connected to the other party due to an emergency or the like, the back-dial operation is performed using the same telephone number, ie, the same line, as in the past.

FIG. 2 is a flowchart of the operation of the main control section 1 when transmitting a document. First, in step 201, the dial information input from the input unit 7 is passed to the auto-dial sending unit 4, and then in step 202, the dial information input from the input unit 7 is passed to the auto-dial sending unit 4.
This dial is sent out to the line. Next step 2
03, the process waits for a line connection, and when it is connected, it is determined in step 204 whether or not an error has occurred. If no error has occurred, the process proceeds to step 207, and if it has occurred, the process proceeds to step 205.

In step 207, image data transmission control is performed in step 20.
Processing is performed up to step 8, transmission end determination. On the other hand, after the line is released in step 205, it is determined in step 206 whether or not the redial operation has been performed a predetermined number of times. In step 209, it is determined whether another line can be used,
If it can be used, go to step 210; if not, go to step 211. In step 210, a different telephone number from the last time is given to the auto-dial sending section 4, and after waiting for a predetermined time in step 212, the process returns to step 202.

In step 211, the same telephone number as last time is given to the auto-dial sending unit 4, and after waiting for a predetermined time in step 212, the process returns to step 202.

According to this embodiment, if a line error occurs after the line is connected and communication fails, a redial operation is performed using another telephone number specifying the same destination, that is, another line. It is possible to avoid this and immediately connect the device to the intended destination and perform communication.

It should be noted that the present invention can be similarly applied to communication devices other than facsimile machines that have an auto-dial function or a dial function to obtain similar effects.

[Effects of the Invention] As described above, according to the facsimile apparatus of the present invention,
If transmission fails due to a line error after line connection, there is an advantage that redialing can be performed using another line network.
