Abstract

PROBLEM TO BE SOLVED: To realize a re-transmission method that is effective when data transmission is stopped on the way. SOLUTION: In the case that transmission is stopped during transmission of data of a plurality of pages, data of a plurality of pages whose transmission is normally finished are magnified/reduced to contain the size of the data within a transmission data size, a message for re-transmission is added to the data to generate a front cover for re-transmission. Then a remaining original image is added to the front over for re-transmission and the data are transmitted again. Furthermore, the number of pages of the data to be added to the re- transmission front cover is limited so as to prevent contents of the front cover from being too much detailed.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data communication apparatus for transmitting data in a storage medium to a partner communication apparatus, and more particularly to a configuration useful for a facsimile apparatus for transmitting a document image after storing the original image in the storage medium.

[0002]

2. Description of the Related Art In recent copiers, especially digital copiers, multifunctional devices such as facsimile machines, printers, and electronic filing devices have been remarkably advanced. In particular, multifunction machines with facsimile machines have become mainstream digital copiers. I have.

Further, the facsimile apparatus is provided with a memory transmission function for transmitting a transmission original after reading the transmission original into a memory, and after reading the transmission original by a scanner, an operator does not wait for the completion of transmission. It is possible to move away from the multifunction peripheral. In the memory transmission, even during transmission, the next transmission original is read and stored in the memory, and the next transmission reservation can be made. Depending on the amount of memory, the number of reservations can be 1000 or more. A large amount of reservations can be made.

[0004] In addition, even if the transmission is stopped halfway, the data of the transmission original is stored on the transmission side until the transmission is completely completed, so that retransmission can be performed. .

[0005]

By the way, there are two methods of retransmission after the transmission is stopped halfway as described above. One is a method of restarting the transmission again from the first page, and the other is a method of restarting the transmission from the page stopped halfway.

However, both of these methods have problems. That is, in the former method of re-transmitting all the pages, a normally transmitted page is also re-transmitted, so that the transmission cost of the page is increased.

[0007] In the latter method of retransmitting from an intermediate page, the first page of the transmission is usually a transmission cover, and even if it overlaps, each cover is used as a guide.
Although it is possible to sort received documents, for example, out of 10 pages of transmitted document A, after up to 4 pages have been transmitted, transmission stops for some reason, and the transmitted document A After the received originals up to the fourth page are output, another three-page original B is received next, and after being placed on the fourth page of the original A, the fifth to tenth pages of the original A are placed. When the received document is retransmitted and output on three pages of another document B, the receiving side intervenes three pages of the document B on the receiving side.
In some cases, it may be difficult to discriminate and sort a received document in which the page document A and the document B are mixed.

In the same example of a 10-page transmission original,
On the receiving side, when the first four pages are in the inbox,
After a recipient removes the four pages from the tray,
If the 5th to 10th pages are retransmitted and output to the Inbox, when another recipient tries to receive it, the received document from the 5th page with no transmission cover will be sent to the sender or destination. There is a risk of becoming unknown.

Accordingly, an object of the present invention is to provide an effective retransmission method when data transmission is stopped halfway.

[0010]

SUMMARY OF THE INVENTION The present invention provides a data communication means for communicating data, a storage means for storing a plurality of pages of transmission data in a storage medium, and a method for transmitting a plurality of pages of transmission data when transmitting the plurality of pages of transmission data. Page management means for managing, retransmission means for retransmitting when transmission stops for some reason in the middle, magnification means for scaling transmission data, and editing means for rearranging the scaled data, A message creation means for creating a message based on character information, and when transmission is stopped halfway during transmission of multiple pages of data, the data of the plurality of pages that have been successfully transmitted is reduced in size to the transmission data size. And a cover creation unit for creating a cover for retransmission and retransmitting by adding a retransmission message.

[0011] The present invention also provides a retransmission cover by adding the retransmission message to data arranged in the transmission data size by scaling down the data of the plurality of pages that have been normally transmitted. A feature is provided in that a restriction unit is provided to restrict and arrange the number of pages of the reduced data to be generated when the data is generated.

FIG. 6 is an explanatory diagram showing an example of a display screen (touch panel) for facsimile operation in this embodiment.

As shown in the figure, when the start key is pressed by inputting a numeric key, a one-touch dial, an abbreviated dial, or the like from a state where transmission is possible, the reading of the document is started. Here, in the case of memory transmission, the reception number is displayed when the document is read into the memory, and the facsimile unit 4 starts the transmission operation. At this time, the next original can be read and the next transmission reservation can be made.

An operation procedure for setting a mode in this embodiment will be described below with reference to FIGS.

First, when "registration management" for setting the mode of the apparatus is selected on the display screen shown in FIG. 6, selection items as shown on the left side of FIG. 7 are further displayed. Then, next, when "user software switch" is selected, FIG.
A selection screen as shown on the right side of is displayed.

Here, "retransmission" is selected, and "from the middle" is selected. Note that this “retransmission” is set to “from the beginning” in the standard mode, and if this setting is maintained, retransmission is performed for all pages.

Next, FIGS. 8 and 9 show the transition of the "user software switch" column when "from the middle" is selected. FIG. 11 is a flowchart showing the flow of control when a retransmission cover is created and retransmission is performed at the time of transmission when retransmission is set to “midway”.

When "from the middle" is selected on the screen in FIG. 7, the screen shown in FIG. 8 is displayed. When "from the beginning" is set, the selection is disabled, and "from the middle" is selected. Allows the user to select the "number of displayed pages" that can be set.

Here, the significance of setting the “number of displayed pages” is that if all transmitted documents are to be placed on the retransmission cover, for example, 100 documents are transmitted,
If 99 pages can be sent and the page stops at the last page and you try to load all 99 pages, the size of one reduced page will be too small, and the content will be indistinguishable. Since it becomes meaningful, the number of pages whose contents can be determined is determined.

In the example shown in FIG. 8, options 1, 2, 4, and 8 are displayed, and the number of pages to be displayed is selected from these options. Note that the reduction ratio of the transmitted document image to be inserted into the resend cover is determined according to the number of displayed pages.

That is, when 1 is selected as the number of displayed pages, one transmitted original image is reduced by about 20% and placed on the cover for retransmission, and when 2 is selected as the number of displayed pages. In other words, the two transmitted original images are reduced to an image slightly smaller than １ ／ and mounted on the resend cover. When 4 is selected as the number of display pages, the four transmitted original images are reduced to an image slightly smaller than 1/4 and placed on the cover for retransmission, and the number of display pages is reduced to 8
Is selected, the eight transmitted original images are reduced to an image slightly smaller than 1/8 and placed on the resend cover.

By such a reduction, an additional area for a message is secured on the cover for retransmission together with the already transmitted original image, and an easy-to-understand cover for retransmission is provided.

Next, the screen shown in FIG. 9 is displayed, and "YES" or "NO" of "hollow display" which can be selected when "display page number" is selected.

This is a specification for selecting a page to be placed on the retransmission cover of the original from among the transmitted originals when the number of transmitted originals is larger than the number of pages set in the “number of displayed pages”.

For example, if “display page number” is set to 4 and the transmitted original is 7 pages, “no”
If you select, the 4 pages to be placed on the resend cover are 1
From page to 4 pages.

Here, when the receiving side receives the already received seven sheets, the retransmitted cover sheet in which the first to fourth pages have been reduced and re-transmitted by retransmission, and the original from the eighth sheet, the cover sheet is displayed. Since only the fourth sheet has been placed, it is conceivable that the connection between the eighth and seventh sheets may not be determined properly.

Therefore, if "Yes" is selected, a page having a value obtained by dividing the number of display setting pages by 2 is selected from the beginning and end. In this case, the setting display page 4 is divided by 2 and each of the two pages is selected, and the first first and second pages and the last six and seventh pages 1, 2, 6, and 7 are selected. The third, fourth, and fifth pages in the middle are removed and placed on the cover.

As a result, the sixth and seventh sheets are displayed on the cover, so that the connection between the eighth document and the seventh sheet can be easily determined.

FIG. 10 is an explanatory diagram showing a specific example of the resend cover created as a result of such selection.

In the illustrated example, the “number of displayed pages” is set to “4”.
Then, the “empty” is set to “Yes”, and the total number of pages of the transmission original is 10, and 7 pages have already been transmitted, and 1, 2, 6,
It has seven pages. Each image is assigned a page number.

The resend cover includes a message to the effect that the cover is a "resend cover" and that a subsequent document is being transmitted. This message is for appropriately reading out the character string information stored in the RAM or the like in advance and adding it to the resend cover.

In S1 of FIG. 11, when the transmission is started in a state where the mode setting at the time of the retransmission as described above is performed in advance (S2), the transmission is completed normally or interrupted due to an error or the like. Is determined (S3), and when the transmission is completed normally, the transmission operation is terminated (S1).
0).

If the transmission is interrupted, the interrupted page is stored and the retransmission mode setting state is referred to, and if retransmission from the beginning is selected (S4). Starts retransmission from the beginning (S
5), proceed to S3.

If retransmission from the middle is selected, it is determined whether or not the skip is selected (S6).
If the blank page is selected, the blank page of the transmitted document is determined based on the specified number of display pages and the information of the interrupted page, and the image of this page is scaled down, The reduced image is arranged at a predetermined address in a memory area for creating a resend cover. Further, a resend cover previously stored in the memory and message data for notifying the contents are called, and the message data is arranged at a predetermined address in a memory area for creating the resend cover. Thereby, for example, a cover for retransmission as shown in FIG. 10 is created (S7).

If the hollow area is not selected, 1
The image is scaled down to the specified number of pages from the first page, and the reduced image is arranged at a predetermined address in a memory area for creating a resend cover in the same manner as in the case of a blank area. Then, a resend cover and a message notifying the content thereof are added to a predetermined address in a memory area for creating the resend cover to create a resend cover (S8).

Then, transmission of the remaining original image is started together with the resend cover created in S7 or S8 (S10).
9) Go to S3. As described above, retransmission can be easily understood.

[0074]

As described above, according to the present invention,
At the time of retransmission, a retransmission cover in which the transmitted document is reduced and placed is created, and the remaining document is transmitted after being added to the retransmission cover, so that retransmission time and transmission cost can be reduced. .

On the other hand, on the receiving side, it is possible to easily and surely determine the connection of the received documents divided and received by stopping the transmission, thereby improving the work efficiency.
