Subsequently, the stored telephone number is read out from the telephone number storage means 5 and dialed by the dial means 7 (step 3). Next, the facsimile means 4
Is activated to detect a response signal from the facsimile of the other party (step 4). Without detecting the other party's facsimile signal,
When a predetermined time has elapsed, the control means 10 stops the facsimile means 4 and controls the line closing means 3 to open the line (step 5). Next, the control means 10 controls the line opening time measuring means 8 to start counting the open time (step 6), and after a predetermined time has elapsed, compares it with the redial number stored in the redial number storing means 9. If the number of redials has not been exceeded, the process returns to step 2 to dial again (step 7). If the number of redials is exceeded, the process ends without dialing (step 8).

[0006]

However, in the above-mentioned configuration, when the facsimile of the other party receives a large number of sheets at the time of transmitting the facsimile, it may be difficult to connect to the other party and the transmission cannot be performed. It is also possible to increase the probability of sending even if the other party is receiving by increasing the number of redials, but due to the characteristics of the telephone line, it is not possible to receive a facsimile while making a call, so the number of redials can be increased. By increasing the number, there is a problem that the risk of damaging the opportunity of facsimile reception is also increased.

The present invention has been made in view of the above prior art. In facsimile transmission, when the other party is busy due to receiving an original or the like, redialing is performed after a predetermined time, and when the other party is busy, (EN) Provided is a facsimile apparatus capable of performing facsimile transmission with a higher probability without increasing the number of redials by controlling a predetermined time so that redialing is performed after a certain processing time.

[0008]

To achieve this object, a facsimile apparatus of the present invention comprises a line closing means for closing a telephone line, a dial means for sending a dial signal to the telephone line, and a telephone line. After the busy tone detection means for detecting the busy tone, the facsimile means for transmitting and receiving the image signal, and the line closing means are controlled, and after the telephone line is closed, the dial means is controlled and the dial is executed. Controlling the facsimile means while monitoring the detection signal from the busy tone detecting means, and controlling the facsimile means to transmit the image signal when the response signal of the facsimile is detected. At the same time, after the dialing of the dialing means is completed, the detection signal from the busy tone detecting means is detected, or the facsimile means is operated by a facsimile machine at a predetermined time. If you do not find the response signal,
The line is closed by controlling the line closing means, and after a predetermined time is processed by a certain function, the line closing means and the dial means are controlled again to execute the dial The sound detecting means and the control means for controlling the facsimile means to perform facsimile transmission.

[0009]

With this configuration, in facsimile transmission, when the other party is busy due to receiving an original or the like, redialing is performed after a predetermined time, and when the other party is busy, the predetermined time is set by a certain function. By controlling the redialing to be performed after the processing time, the facsimile transmission can be surely performed without increasing the number of redialing.
