Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile apparatus for storing set document information in a memory and for making a call based on a preset telephone number and automatically transmitting the stored document information.

[0002]

2. Description of the Related Art In a conventional facsimile machine of this type,
When the original is set and the dial operation is performed, this dial number is stored in the memory, and when the start key is pressed subsequently, the information of the set original is read and encoded and stored in the memory. It The information of the original set in this way is sequentially stored in the memory for each page, and when the storage of all the original information is completed, the line is automatically captured, and the dial number stored in the memory is sent to the capture line. An automatic call is made, and the original information stored in the memory is sequentially transmitted to the other device for each page in response to the response from the other facsimile device.

[0003]

Conventionally, in this type of facsimile apparatus, if a communication error occurs during the transmission of document information, an error state occurs, the subsequent facsimile transmission is terminated, and the document with the error occurs. The original information including the pages of the following is deleted from the memory. Therefore, if a transmission error occurs, the operator must call the other party to confirm that it will be retransmitted, and then set the originals of the subsequent pages including the abnormal page and send them again. However, there is a problem that the load on the operator increases.

[0004]

In order to solve such a problem, the present invention relates to a communication abnormality detecting means for detecting a communication abnormality based on an abnormality of a facsimile machine or a line at the time of transmitting document information, and the communication abnormality detecting means. When a communication abnormality is detected by the detection means, the control means stores the page of the document information being transmitted, disconnects the line for a certain period of time, and retransmits from the stored document information of the page. ..

[0005]

When the communication abnormality is detected, the page of the document information being transmitted is stored, and after a predetermined time, the document information of the stored page is automatically retransmitted.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of a facsimile apparatus according to the present invention. In the figure, 1 is a CPU for controlling the entire facsimile apparatus, 2 is a line such as a telephone line, 3 is a DP generation circuit for generating a DP (dial pulse) signal to be transmitted to the line 2, and 4 is a facsimile information transmission / reception. A modem, 5 is a voice message circuit for transmitting a voice message to the line 2, 6 is an incoming call detection circuit, and 7 is 1
6H _Z ringer generation circuit, 8 is a hook switch.
Further, 9 is an image sensor for reading the information of the set original, 10 is a thermal head for recording the received original information on a recording sheet, 11 is a dial key, 12 is a communication key for starting facsimile communication, and 13 is a receiving key. A memory for storing document information to be transmitted or document information to be transmitted, 14 is a display circuit, 15 is a speaker, 16 is a recording paper detection sensor for detecting the presence or absence of recording paper, and 17 is a black end mark marked on the recording paper. Black end mark detection sensor, 1
8 to 20 are contacts, 21 is a transformer, and 22 is a built-in telephone. The built-in telephone 22 is composed of a contact point 30, a ringer 31, a communication circuit 32, and a handset 33 that interlock with the operation of the hook switch 8.

This facsimile apparatus can automatically switch between a call mode and a facsimile mode. In the telephone mode, the contacts 18, 19 and the contact 30 are provided.
Are switched to the b side, and the contact 20 is switched to the a side. In this case, when the incoming signal comes from the line 2, it is sent to the built-in telephone 22 via the contacts 18 and 19, and as a result, the ringer 31 rings. Then, the off-hook of the built-in telephone 22 causes the contact 30 to be switched to the side a so that a call with the other party becomes possible.

Further, in the facsimile mode, the line 2
When an incoming signal comes from the incoming call signal, it is detected by the incoming call detection circuit 6 and notified to the CPU 1. When the CPU 1 receives the notification of the incoming call, it switches the contact 19 to the side a and responds to this, drives the voice message circuit 5 to send out a predetermined message, and then transmits the facsimile information from the partner device via the modem 4. It is supposed to be received.

Further, in the case of performing facsimile transmission in the facsimile mode, when a manuscript is set and the dial key 11 is operated, the manuscript is stored as a dial number in a predetermined area of the memory 13, and the manuscript described above is also stored. Is read for each page, encoded, and stored in the memory 13. When the communication key 12 for starting the facsimile communication is pressed, the contacts 18 and 19 are switched to the side a to capture the line, and the dial signal from the DP generation circuit 3 is generated based on the stored dial number. Is transmitted to the line 2. When the partner device responds, the document information stored in the memory is transmitted to the partner device via the modem 4 and the line 2.

Next, FIGS. 2 and 3 are flow charts showing the operation of the CPU 1 in the facsimile apparatus. That is,
When performing facsimile transmission using this facsimile transmission, first set the original and dial,
“Pressing start button” in step 100 is “N”,
And "pressing the dial button" in step 101 is determined to be "Y", and "document is present" in the following step 102.
Is "Y", the dial number is stored in the memory 13 in step 103. In this case, if no original is set, a reject sound is generated in step 104 and the process returns to step 100.

When the start button (communication key 12) is pressed to start facsimile communication after the dial number is stored in the memory 13 in this way, the "press start button" in step 100 is "Y", and step 105
Since it is determined that "already pressed the dial button" is "Y", the process proceeds to step 110. If the dial number is not stored in the memory 13 by pressing the dial button 11, it is determined as "N" in step 105. In this case, a rejection sound is generated in step 106 and the process returns to step 100.

In step 110, "1" is set in the memory page counter, and subsequently, in steps 111 to 113, reading of the original, encoding processing of the read original information, and storage in the memory 13 are sequentially executed. When the processing is executed for one page of the manuscript, “1
“End of page” is determined to be “Y”. Then, in this case, the process proceeds to step 115 to further determine "all page end", and if the reading / storing process of all pages of the document is not completed, the process returns to step 111 to start reading the document of the next page.

When the information of all pages of the original is read and stored in the memory 13, the process proceeds to step 120. In this case, the communication abnormality flag is set to "0" (step 120), the value of the recalling counter that defines the number of outgoing calls is set to "3" (step 121), and the line 2 is captured in step 122. .. Then, after capturing the line, a wait (wait) for 3 seconds is performed (step 12).
3) After that, the dial call processing for sending the dial number stored in the memory 13 to the line 2 is executed (step 124).

Then, in step 125, it is determined whether or not a communication abnormality has occurred in facsimile communication. In this case, since facsimile communication has not been performed yet, the determination in step 125 is "N", the transmission page counter indicating the page of the transmission original is set to "1" (step 126), and the header transmission flag is set to "0". "
(Step 127), and the process proceeds to the "pre-communication procedure" process of step 130 of FIG. If a communication error occurs due to facsimile communication, step 12
The determination in 5 is "Y", and in this case, the value of the abnormal page counter indicating the page of the original that has become abnormal is set in the transmission page counter (step 128), and in step 129 the header transmission flag described later is set to "1. Set to.

Next, in step 130 of FIG. 3, a "pre-communication procedure" process is executed with the partner device, and if this process is normally performed, it is determined as "N" in steps 131 and 132, In step 133, it is determined whether the header transmission flag is set. This header is for notifying the fact when the original document in which the communication is abnormal is retransmitted, and its format is shown in FIG. Then, if the communication is normally performed, step 13
The judgment of No. 3 is “N”, and in this case, the document information of the page designated by the value of the transmission page counter is stored in the memory 13
In step 134, the process of reading out the image data and transmitting it to the line 2 (image signal transmission process) is executed. Then, after the manuscript information of the pertinent page is transmitted, the process proceeds to step 135 to execute the "post-communication procedure" processing, and if this communication is normally performed, the value of the step memory page counter is determined in step 136. Compare with the value of the transmission page counter. Then, if the values of these counters do not match, it means that the transmission original of the next page exists, so that step 13
In step 8, the transmission page counter is incremented by "1", and then the document information of the next page is transmitted. Therefore, the image signal of the next document is transmitted in step 134 through "N" in step 133.

In this way, the information of the transmission original is transmitted for each page, and when all the transmissions are completed, it is judged as "Y" in step 137. In this case, step 140
The recalling counter is set to "0" at step 141, the line is disconnected at step 141, and "callback counter = 0" at step 142 is determined to be "Y". State ".

Further, as a result of the "pre-communication procedure" processing in step 130, the response from the partner device is a time T1 of about 30 to 40 seconds.
If it cannot be detected and the result is “Y” in step 131, the process proceeds to step 141 and the line is immediately disconnected. Further, when a communication abnormality is detected in the process of communication processing performed after the response of the partner device (in the case of “Y” in step 132), and “post-communication procedure” executed after the transmission of the image signal.
When a communication error is detected in the process of processing (step 13
In the case of "Y" in 6), the value of the transmission page counter is set to the abnormal page counter (step 150),
The communication error flag is set to "1" (step 151) and the line disconnection process of step 141 is executed. Then, in this case, it is determined in step 142 whether or not the value of the recalling counter is "0". If it is not "0", the value of the recalling counter is decremented by "1" in step 152, and then step 153.
And wait for 2 minutes. When the time of 2 minutes elapses in this way, the process returns to step 122 of FIG. 2 to capture the line 2 again and retransmit the document information.

When a communication error occurs and the document information is retransmitted, the "communication error flag = 1" in step 125 becomes "Y", and as a result, the transmission page counter indicates the page of the document in which the error occurred. The value of the abnormal page counter is set (step 128), and the header transmission flag is set to "1" in step 129. As a result,
Since the determination of “header transmission flag = 1” in step 133 is “Y”, the above header is transmitted (step 154), the header transmission flag is set to “0” (step 155), and communication is performed. The image signal is retransmitted from the original of the page where the abnormality is detected.

As described above, when a communication error occurs during the transmission of the document information, the line is disconnected and after 2 minutes elapses, the line is captured again to call the facsimile machine of the other party, and the header is transmitted. An untransmitted document is automatically transmitted sequentially from the page of the document in which the abnormality has occurred. In the present embodiment, the number of re-calls when a communication abnormality occurs is set to 3 (because the re-call call counter value is set to "3"), but it may be set to any number. Time until dialing after capturing the line, and
The time after disconnecting the line until the next line is captured is 3 seconds and 2 minutes, respectively, but these may be set to arbitrary times.

[0020]

As described above, according to the present invention,
When a communication abnormality is detected, the page of the document information being transmitted is stored, and after a certain period of time, the document information of the stored page is automatically retransmitted, so that the burden on the operator can be reduced.
