Abstract

PURPOSE:To execute polling communication again from a page on which a communication error takes place by sending a polling reception start page for retransmission to a called party at the restart of polling reception so as to interrupt the line once and redialing the called party. CONSTITUTION:When a communication error or the like rakes place during polling reception and a polling transmission page is designated in the polling transmission after the communication error, a called party uses a transmission/ reception means 34 to start polling transmission from the designated page. When a communication error or the like takes place in a caller side, a polling reception start page is indicated from page information of a count means counting a reception page and the caller sends the polling reception start page for retransmission to the called party at the restart of polling reception. The start page for polling transmission is commanded to the called party receiving the page information. Thus, the line is once interrupted when a communication error takes place and then the communication line is connected again.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a facsimile device having a polling communication function.

[Background of the Invention] Some facsimile machines are equipped with a polling communication function.

As is well known, the polling communication function, for example, the polling reception function, is a function that allows the originating RFF-side to automatically receive a document from the called side.

In this case, the called party's manuscript is usually stored in the memory means, and the data is transmitted in response to a request from the calling party.

[Problems to be Solved by the Invention] When, for example, a communication error occurs during such polling communication, the Tsujo Tsusho line is automatically disconnected. Therefore, when attempting to poll-receive a document after a communication error has occurred, it is necessary to set polling reception again and receive the document again from the calling side.

In this case, since this second polling reception is exactly the same as the normal polling reception ε, the reception start page for polling reception starts from page 1.

Therefore, if a communication error occurs and the line is disconnected during polling transmission, the document must be received again from page 1, which has the disadvantage of taking communication time and wasting recording paper. .

Therefore, this invention takes these points into consideration, and if a communication error occurs during polling call ε, the line will be disconnected, the call will be made again, and the page where the communication error occurred will be displayed. The polling communication is re-executed.

[Means for Solving the Problems] In order to solve the above-mentioned problems, in the present invention, as a called side function, a memory means for a document for polling transmission and whether or not to erase the memory contents after all pages are transmitted are provided. and determining means for determining the polling transmission designated page from the calling side, and when a polling transmission page is specified in polling transmission after a communication error, polling transmission is performed from that designated page. This feature is characterized in that it starts.

Roughly speaking, in this invention, the functions of the calling side include a counting means for counting the number of pages received during polling reception, a reception error detection means, and a means for instructing a polling reception start page from the page information of the reception error opening means. The present invention is characterized in that it has an instruction means and a means for restarting polling reception in the event of a reception error, and when restarting polling reception, the above-mentioned polling reception start page for retransmission is transmitted to the called party. It is something to do.

[Function 1] If a communication error or the like occurs during polling reception, the calling and called parties can complete the re-polling process by following the steps below.

First, on the called side, in polling transmission 8 after a communication error, if a polling transmission ε page is specified, polling transmission is started from that designated page (see FIG. 1).

On the calling side, when there is a communication error, the polling reception start page is specified from the page information of the counting means that counts the received pages, and when polling reception is restarted, the polling reception start page for retransmission is sent to the called side. (See Figure 2).

According to this, after an error occurs during polling reception and the line is automatically disconnected, the polling reception is disabled again.
mode is executed. At this time, the calling side specifies the polling reception 4g start page, and in response, the called side instructs the start page for polling transmission. As a result, polling transmission ε will not be exhausted for pages that have already been transmitted.

In addition, when a communication error occurs like this, the line is temporarily disconnected and then reconnected, so when the line is connected for the second time, the communication status may be different from the previous one. can be considered, and the probability that an error in communication will occur is reduced.

[Embodiment] Next, an example of a facsimile device having a polling function 4 according to the present invention will be described in detail with reference to FIG. 1 and subsequent figures.

1 and 2 show functional block diagrams of the present invention, with FIG. 1 showing a functional block diagram on the called side, and FIG. 2 showing a functional block diagram on the calling side.

In FIG. 1, 30 is a document reading means.

For example, a line sensor such as a CCD can be used for this. 32 is a memory means for storing read image information. As this memory means 32, a RAM or the like can be used. 34 is a transmitting/receiving means to which a communication line such as a general public line can be connected.

36 is means for determining a polling transmission designated page,
When there is a page designation at the time of polling transmission in the received signal obtained from the transmitting/receiving means 34, the memory means 32 is controlled based on information to that effect.

Further, 38 is a setting means for setting whether or not to erase the contents of the memory means 32, and this means to erase the contents after all the pages stored in the memory means 32 for polling transmission have been transmitted. This is for selecting whether to erase or not. Therefore, whether or not to erase the memory can be specified manually.

FIG. 2 shows a functional block diagram of the calling side during polling reception, and 40 indicates a transmitting/receiving means, which is the same as the transmitting/receiving means 34 shown in FIG.

42 is a means for counting received pages. 44 is reception error detection means. Reference numeral 46 designates a reception start page, and the count contents of the counting means 42 when a reception error occurs are designated as the reception start page.

Reference numeral 48 denotes a polling reception restarting means, which is used to restart the apparatus so as to enter the polling reception mode again when a communication error or the like occurs.

By doing this, the polling reception mode can be restarted, and at that time, information indicating the reception start page is transmitted to the called party via the transmitting/receiving means 40.

As a result, the called side reads the corresponding page from the memory means 32 from the polling transmission designated page corresponding to the receiving (g start page) and enters the boring reception mode.

Among the above-mentioned means, all of the plurality of means except the transmitting/receiving means 34 are designed so that their functions can be achieved by software. Therefore, in order to achieve these functions, the facsimile machine is equipped with communication control means 1 as shown in Figure 3.
0 is set.

In the figure, 11 is a CPU that manages transmission and reception control as described above.

Reference numeral 12 designates a ROM 113 in which a control program for achieving the above-mentioned polling reception function is stored, and a RAM memory that can be used for storing image data.

Therefore, this RAM memory 13 is the memory means 3 mentioned above.
During polling reception, each page information (image data) read by the original reading means (original reading unit) 30 is stored in this RAM memory 13.

The image data read by the document reading means 30 is stored in the RAM 13 via the interface 15, and then
or directly to the modem and network control circuit (NCU) 16. The image data input from the line is sent via this modem and NCtJ 16, either directly or to the RAM 1.
3, and then supplied to the recording unit 18 via the interface 17 and recorded.

The telephone number of the destination party is supplied to the display section 20 via the interface 19, and is displayed thereon. Reference numeral 21 is an operation unit for inputting a telephone number, etc., and 22 is an interface thereof.

In order to achieve the above-mentioned polling communication function, the present invention stores a control program as shown in FIG. 4 and subsequent figures. For convenience of explanation, an example of the polling transmission function will be explained in detail from the called side.

FIG. 4 is a flowchart showing an example of the polling transmission set processing 50. When setting the polling transmission, first, the polling transmission 8 original is read, and the image data is stored page by page in the memory means 32 (
Step 51).

Thereafter, the presence of a polling transmission function from an arbitrary page is set in the function table as a called terminal communication function (step 52).

This enables polling transmission from the specified page.

Further, after all pages of the file for polling transmission have been sent, the user's selection for determining whether or not to automatically delete the file is set in the memory (step 53). As mentioned above, this is done by the memory erase setting means 38, and this is done by the operation section 21.
This is done by operating the keys provided above.

FIG. 5 is a flowchart illustrating an example of incoming call processing 60 on the called side.

When this incoming call processing is started, the information having the function set in the function table as described above, that is, the polling transmission function from any page, is sent as a procedure signal, that is, the NS
It is added to the F signal and sent to the calling side (ε) (step 6
1).

Thereafter, it is checked whether the transmission right has been transferred from the calling party to the called party (step 62).

To check whether the transmission right has been transferred to the called party, check the DC3C12NSS signal, D
This can be checked by identifying the TC48 or NSC signal.

That is, when the calling party has sent the DC5 signal or the N554g signal, the transmission right has not yet been delegated to the called party, so in this case step 63 is executed.
, and executes normal reception ε processing.

On the other hand, when a DTC signal or NSC signal is sent from the calling side, it is understood that the transmission right has been transferred to the called side. Check if there are any instructions (
Step 64).

If there is no instruction for the transmission start page, the transmission page number is set to page 1 (step 65) and the process moves to the polling transmission processing routine (step 70).
.

In a normal polling communication state where no communication error occurs, the transmission start page is normally set to 1 page.

On the other hand, when a communication error occurs and the transmission start page is specified, the transmission page number is set to the specified value (step 66).
The process moves to the polling send ε process routine (step 70), and the polling send process is executed again.

FIG. 6 is a flowchart illustrating details of the polling transmission process 70 shown in FIG.

When the control program for polling send 8 processing is activated, first the page in the RAM memory 13 corresponding to the set send page number is sent (step 71). Thereafter, it is checked whether a communication error has occurred in the transmitted page (step 72), and if a transmission page error has occurred, the polling transmission process is immediately terminated.

On the other hand, if no error has occurred in the sent page, check the last page of the sent pages (step 73); if it is not the last page, increment the sent page number, set the next page number, and then step Returning to step 71, similar page transmission processing is executed again (steps 74 and 71).

When the transmission page reaches the final page, it is next determined whether automatic file deletion is specified (step 75), and if automatic file deletion is specified,
Even if the files of all the pages that have already been transmitted have been deleted (step 76), the polling transmission function mode is reset from the function table and returned to the initial state (step 7).
7). This completes the polling transmission process.

Therefore, as described above, if a communication error occurs during the process, the calling side specifies a transmission start page, and polling transmission is started from that page.

7 and subsequent figures show an example of a control program on the calling side, and FIG. 7 is a flowchart showing an example of the polling receiver 8 activation process 80 on the calling side.

In this polling reception startup routine, first the time for polling reception is set. If no polling reception time is specified, the polling reception state is immediately set (step 81).

Next, the reception start page for polling reception is set to page 1 (step 82). This is the designation of the reception start page in the normal polling reception mode, and is the same as the conventional one.

Subsequently, the number of error redials for polling reception is set to n times (step 83). It is usually preferable to set the number of error redials n to 2 to 3 times. When a communication error occurs as a result, a line connection request is made to the called party at least n times.

In that case, each time a line connection request is made, it is assumed that the connection route of the communication line with the other party will be different, and in this case, the status of the communication line will be different from before, so it is possible that a communication error occurred previously. However, the line condition often improves after the second line connection, so the probability of a communication error occurring is extremely low.

FIG. 8 is a flowchart showing an example of polling reception processing 90 on the calling side. First, it is checked whether the other party's machine, that is, the called side has a polling transmission function (step 91), and then the polling transmission is performed. If the function is not available, the polling communication process cannot be executed and the process ends with an error.

On the other hand, if there is a polling transmission function, which is a type of non-standard function, it is checked whether the other party's device has a polling transmission function from an arbitrary page (step 92).

Whether there is a polling transmission function from any page,
NSF <8 sent from the called party as described above.
It can be easily identified by looking at the contents of the number.

If this polling transmission function is not available, a normal polling transmission mode is instructed, and then a transition is made to normal polling transmission processing (steps 92, 93, and 94).
.

These steps are the current polling and sending processing functions.

On the other hand, if the polling transmission function from any page is available, the other party is instructed to perform polling transmission and the polling reception start page is simultaneously instructed (step 100). Thereafter, the polling reception (g start page) is set in the page counter (step 101).

Next, the mode goes to 1 page reception mode (step 10).
2) The received page is checked to see if there is a communication error (step 103), and if there is no communication error, the last page of the received page 8 is checked (step 1).
04), if it is not the last page, the page counter is incremented to the next number (step 105).

After that, the process returns to the one-page reception mode (step 102).

Then, when it is checked in step 104 that the received page is the last page, the operation for polling reception (ε) is completed, the polling reception start page is cleared, and the polling reception process ends (step 106).
).

In contrast to the above normal reception mode, if an error occurs in the received page, this is step 1.
In this case, the number of error redials for polling reception ε is incremented by 1 (step 107). In other words, when this communication error occurs, the communication line is immediately disconnected, and a line connection request is automatically sent to the called party.
(redial processing).

Then, line connection processing is automatically executed by such dialing processing, but in this case, it is determined whether a prescribed number of error redials has been exceeded (step 108), and if this prescribed number of times n has not been reached, After the polling reception operation is determined to be incomplete and a predetermined period of dialing standby time is given, polling reception is set again (step 109). As a result, the communication line is set again, and polling reception from the designated page is executed based on the designation of the reception start page described above.

On the other hand, if the communication line condition is very bad and the communication line does not return to normal even after exceeding the specified number of error redials, the polling reception operation is completed.
The polling reception start page is cleared and the polling reception 8 processing is ended (step 110).

In the above, when the calling side detects that a communication error has occurred, the calling side specifies the transmission start page, but when the called side detects that a communication error has occurred, , After automatically disconnecting the communication line, the calling side executes polling reception 8 processing from the called side to the called side, and at that time, the called side performs polling transmission ε from the page where the communication 8 error occurred. It is also possible to configure it as follows.

[Effects of the Invention] As explained above, in this invention, if a communication error occurs during polling communication, the line is disconnected once and then the call is made again, and the polling communication is restarted from the page where the error occurred. It was designed to be executed.

According to this method, unlike the conventional method, it is not necessary to perform polling transmission from the first page, so that it is possible to simultaneously save the communication time and the amount of recording paper, which is very convenient for practical use.
