Abstract

PURPOSE:To prevent trouble to the call incoming side by clearing the number of times of call reorigination when a disconnect signal is detected before a response is received. CONSTITUTION:A control means 6 inputs an opposite side dial number operated by an operating means 10 and automatically sends this number to a telephone line 4 by controlling an automatic dial means 5. When the response of the party is detected through a tone receiving means 7, the image information of an original or the like passed through an image input/output means 1 is transmitted through a speaking circuit 3 and the line 4 by controlling an image data transmitting/receiving means 2. When the end of facsimile communication is inputted through the means 2, the means 6 outputs a report showing the normal end of instructed communication from the means 1 to a communicated result reporting means 8. When the facsimile communication is not performed with the opposite side equipment even by originating a call to the opposite side equipment, call reorigination is repeated just for the previously set number of times. When a call is originated to the other equipment, the call reorigination to the other relevant equipment is automatically recovered. Thus, the trouble to the call incoming side can be prevented by preventing repeated erroneous call incoming to the same terminal.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile machine having an automatic recall function, and more particularly to a facsimile machine with an automatic recall function for recovering the automatic recall function.

[0002]

2. Description of the Related Art A conventional facsimile machine of this type is disclosed in, for example, Japanese Patent Application Laid-Open No. 2-79548. That is, in this facsimile apparatus, when transmitting image information from the calling side to the receiving side, first, the caller dials the terminal number of the calling party, and the automatic re-calling section is activated. Then, when the other party's terminal which is the call destination does not respond, redialing is performed a predetermined number of times. Also,
If the callee is not the facsimile machine and the number of the ordinary telephone is mistakenly dialed, the corresponding ordinary telephone is called. The call is made. Here, when the operator of the called general telephone responds to the call, a dial tone or the like is heard from the facsimile apparatus on the calling side. When the operator hears this, it judges that the call is a facsimile call and dials a predetermined specific number. The dialed digit information is transmitted to the calling side facsimile machine and received by the numeral receiving monitoring section of the calling side facsimile machine. When the numeral reception monitoring section receives this numeral information, it sends a detection signal to the forced restoration section, and the forced restoration section forcibly restores the automatic re-sending section based on this detection signal, and the display and alarm sound The sender is notified of the mistaken dialing of the other party's terminal number by sending or the like. As a result, redialing to the same terminal based on an erroneously operated dial number is prevented, and the caller can redial the correct partner terminal number.

[0003]

However, the conventional method for recovering the redialing in the case of making an erroneous call by erroneous dialing is that the called called subscriber sends numerical information to the calling side device after answering the incoming call. However, there is a problem that automatic redialing to the same terminal cannot be restored if such a means for transmitting numerical information is not provided on the receiving side.

Therefore, it is an object of the present invention to restore automatic redialing even when the called side is not equipped with a means for sending numerical information when a call is made to another terminal by erroneous dialing.

[0005]

In order to solve such a problem, a first invention is a facsimile response signal receiving means for receiving a facsimile response signal from a terminal responding to a call, and a response to the call. A disconnection signal detecting means for detecting a disconnection signal of the terminal and a means for clearing the set number of recalls when the disconnection signal is detected before receiving the facsimile response signal are provided. A second aspect of the invention is to measure the time from the response of the terminal to the disconnection, and the time measuring means for detecting the disconnection signal before receiving the facsimile response signal and the time measured by the time measuring means is shorter than a preset predetermined time. In this case, a means for clearing the number of recalls is provided.

[0006]

When the disconnection signal of this terminal is detected before the facsimile response signal is received from the responding terminal, the number of recalled calls set by the recalled call setting means is cleared.
If the disconnection signal of this terminal is detected before the facsimile response signal is received from the responding terminal and the time from the response to the call from the terminal to the disconnection is shorter than the predetermined time, the number of re-calls is cleared.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of a facsimile device with an automatic recall call recovery function according to the present invention. The device calls (or makes) a call to a partner terminal prior to transmitting image information to the partner terminal. When the other terminal does not respond, a call can be made again, and if a call is made to another terminal by mistake, the recall operation for the other terminal can be automatically restored.

In FIG. 1, the image input / output means 1 is connected to the image data transmission / reception means 2, the image data transmission / reception means 3 is connected to the call circuit 3, and the call circuit 3 is connected to the telephone line 4. . The automatic dial means 5 is connected to the telephone line 4 and sends out the dial number (dial number of the other party) of the called subscriber via the telephone line 4 to a network (not shown) according to an instruction from the control means 6. The tone receiving means 7 also receives a tone signal from the network and sends it to the control means 6. The communication result reporting means 8 sends the communication result to the image input / output means 1 in response to the signal from the control means 6. The clock means 9 and the operating means 10 are respectively the control means 6
It is connected to the.

Here, when the image information is transmitted to the facsimile apparatus which is the partner terminal by using this apparatus, the control means 6 inputs the partner dial number operated by the operation means 10 to control the automatic dial means 5. Then, this dialed number is automatically transmitted to the telephone line 4. When the response of the partner device is detected via the tone receiving means 7, the image data transmitting / receiving means 2 is controlled to send the image information of the original or the like via the image input / output means 1 to the partner device via the communication circuit 3 and the line 4. Let When the control means 6 inputs the end of the facsimile communication via the image data transmission / reception means 2,
The communication result reporting means 8 is instructed to cause the image input / output means 1 to output a report indicating the normal termination of communication. If facsimile communication is not performed with the partner device even if the call is made to the partner device, re-calling is repeated for the same device a preset number of times. When a call is made to another device by mistake, the operation of re-calling the other device is automatically restored as described above.

Next, FIG. 2 is a flow chart of the control means 6. The detailed operation of the apparatus of the above embodiment will be described based on this flowchart. When the operation unit 10 receives the designation of the image information transmission time to the partner device, the incoming dial number (dial number of the partner device) and the number of re-calls (the number of re-calls; the number of re-originations), the control unit 6 omits them. Set in the internal memory that has been set and stored, and step S
At T1, the current time of the clock means 9 is compared with the transmission time,
If this is coincident and it is determined to be "Y", step ST
In step 2, the station line is closed, that is, the direct current loop of the telephone line 4 is closed, and in step ST3, the automatic dialing means 5 is controlled to perform dial transmission for automatically transmitting the incoming dial number.

After that, in step ST4, the signal sound coming from the network through the telephone line 4 is monitored for a predetermined time through the tone receiving means 7, and the signal sound is received during this time, and it is determined as "Y" in step ST4. Then, it is determined in steps ST5 and ST6 whether the received signal tone is a busy tone or a ring bank tone, the ring back tone is received, and the stop of this tone is detected, and the determination in step ST5 is "N". ] And step ST6
If the answer is “Y”, it means that the response from the other party has been detected and the call with the other party device has been started, and the call start time is stored in the memory in step ST7.

After the call is started, the answering party, that is, the other party's device is disconnected in step ST8, for example, the telephone line 4
If the line disconnection is not detected, it is judged whether the predetermined time timer started at the time of setting the call start time in step ST7 is time out.
Perform at 9. If a facsimile response signal such as a CED signal of a G3 facsimile is detected and "Y" is determined in step ST10 while the timer does not time out, a step of transmitting and receiving a FAX (facsimile) message indicating communication of image information is performed. It is performed in ST11, and when this is completed, the completion report indicating the completion of communication is instructed to the communication result reporting means 8 in step ST12, and in step ST13, the loop of the telephone line 4 is released and the process is terminated.

When the disconnection of the partner device is detected after the stop of the ringback tone is detected and the call with the partner device is started and the determination in step ST8 is "Y", the process proceeds to ST14 and the clock is started. The time information from the means 9 is obtained and the disconnection time is stored, and whether or not the communication time which is the difference between the call start time in step ST7 and the disconnection time in step ST14 is longer than a predetermined time (for example, 30 seconds) is determined. The judgment is made in step ST15. If the call time is shorter than the predetermined time, it is judged that the terminal, such as another telephone, has received a call due to an erroneous call, not the call to the facsimile machine, and the terminal that responded to the call has been disconnected, and step ST1
Go to 6 and clear the number of recalls, and step ST
In step 17, the communication result reporting means 8 is instructed to output a cancellation report indicating cancellation of facsimile communication, and in step ST13, the loop of the telephone line 4 is released and the processing is terminated. Therefore,
In this case, automatic redialing to the same terminal by sending the same incoming dial number is prevented.

Further, the call time is long and the step ST1
When it is determined to be "Y" in 5, or when the facsimile response signal is not detected from the partner device even if a predetermined time has elapsed after the start of the call, and it is determined to be "Y" in step ST9, and the predetermined time has elapsed after dialing. Even if the signal tone from the line 4 is not detected and it is determined to be "N" in step ST4, or if the busy tone from the line 4 is detected after dialing and the determination is "Y" in step ST5, and If the ring back tone is continuously detected because the other party does not answer the call after dialing and it is determined to be "N" in step ST6, the loop of the telephone line 4 is released and the processing of step ST18 and thereafter is executed. .

That is, in step ST18, the number of recalls is determined, and if the number of recalls does not reach a predetermined set value, the time of recall is set in step ST19, and step S19 is performed.
Return to T1. Then, at the time of re-call, the office line is closed again and re-calling to the same terminal is performed. In this way, the re-calling operation is performed for the same terminal a predetermined number of times until the partner terminal responds, and the number of re-calls becomes equal to or greater than the predetermined value.
If it is determined to be "Y" at T18, the communication result reporting means 8 is instructed to output the incompletion report indicating the incompletion of the facsimile communication at step ST20, and at the same time step ST1.
3, the loop of the telephone line 4 is released, and the process ends.

As described above, the dialing is performed to detect the response of the partner device, the disconnection signal is detected before receiving the facsimile response signal from the partner device that responded, and the time from the response to disconnection is less than the predetermined time. If not, the number of times of recall is cleared as an erroneous call due to erroneous dialing, and the same device is prevented from making a call again. As a result, erroneous dialing based on erroneous dialing is reliably detected, and subsequent redialing to the same terminal device can be prevented, so that it is possible to prevent annoyance to the called party due to erroneous incoming call and reduce telephone charges and network load. Will be possible. In addition,
In the present embodiment, when the disconnection signal is detected before the reception of the facsimile response signal from the partner device, if the time from the response to the disconnection is the predetermined time or more, redialing is performed. It may be configured to clear the number of re-calls and prevent re-calling even in the case of a predetermined time or more.

[0017]

As described above, according to the present invention,
When the disconnection signal of this terminal is detected before the facsimile response signal is received from the responding terminal, the number of recalled calls set by the recalling call setting means is cleared, so that the called party is called again. Even if the means for sending out numerical information for stopping is not provided, the subsequent re-call to the same terminal is restored, and therefore, repeated false call to the same terminal due to false call is prevented, and it is annoying to the called party. There is an effect that the telephone charge can be reduced and the load on the network can be reduced. Also, if the disconnection signal of the terminal is detected before receiving the facsimile response signal from the responding terminal and the time from the response of the terminal to the disconnection is shorter than the predetermined time, the number of recalled calls is cleared, so There is an effect that false calls can be detected to prevent re-calls.
