Abstract

PROBLEM TO BE SOLVED: To reduce the running cost by combining plural pages of image data while arranging their main scanning length within a range not in excess number of recordable lines so as to form an image by one page and sending the resulting image. SOLUTION: In the case of storing read image data into an image memory once and sending the stored data depending on a reception number, image data of plural consecutive pages are combined within a range not in excess number of recordable lines of a receiver side facsimile equipment and the resulting data are sent as image data by one page. In this case, when main scanning line length of the image data of the plural consecutive pages is different, left and right blank image data are added to arrange the main scanning length (S307) and then lower blank image data are added so that the image data of the plural consecutive pages are recorded on equally distributed positions on recording paper (cut paper) (S306) and the result is transmitted (S311). In the case of recording the data onto one recording paper at a receiver side, since the data by two pages are sent as one page, the blank part of the recording paper is reduced.

That is, in the present embodiment, when the read image data is once stored in the image memory 13 and transmitted by reception number, as shown in FIG. 2, within the range that does not exceed the recordable line number of the receiving side facsimile apparatus. The image data of a plurality of consecutive pages is combined and transmitted as image data for one page.

At this time, when the main scanning lengths of the image data of a plurality of consecutive pages are different, the left and right margin image data are added to make the main scanning lengths uniform, and the image data of a plurality of consecutive pages are recorded. Lower margin image data is added and transmitted so that the data is recorded at equally divided positions on a sheet of paper (cut sheet).

In this embodiment, facsimile transmission / reception is performed by a signal sequence conforming to the binary code control procedure of ITU-T Recommendation 30.

Next, the memory transmission operation in this embodiment will be described with reference to the flowcharts of FIGS. It should be noted that this flow is a flow assuming that the resolution is the same for all pages.

First, the CPU 1 executes a signal sequence conforming to the binary code control procedure to obtain a DIS signal (digital initial identification signal) containing the size and resolution capability of the recording paper on the side of the facsimile machine of the transmission destination. ), The maximum recording main scanning length W and the number of recordable lines Y are determined and set (step S30 in FIG. 3).
1). For example, if the reading document width is A4 size, the recording paper width and length of the receiver are A4 size, and the reading resolution is standard, the maximum recording main scanning length W that can be recorded on the A4 size recording paper at the standard resolution is "1728. “1144” is set, and “1144” is set as the recordable line number Y.

Next, "1" is initialized to the page counter i as the page number, and W is set to the main scanning length W1 of the image data of the first page among the plurality of image data associated with the receipt number (( Step S302). And
From the image data stored in the reading buffer of the image memory 13, the image data of the page of the number indicated by the page counter i (hereinafter referred to as i) is read out and is transmitted to the transmission buffer (formed in the image memory 13). Stored) (step S303).

The next page, that is, (i + 1)
It is determined whether or not the image data of the page is stored in the image memory 13 (step S304). as a result,
If the image data of the (i + 1) th page is stored,
The sum (Xi + Xi + 1) of the reading line number Xi of the i-th page and the reading line number Xi + 1 of the (i + 1) th page is less than or equal to the recordable line number Y, and the reading line number X of the i-th page.
It is determined whether or not the number of read lines Xi + 1 of the i, (i + 1) th page is both 1/2 or less of the number of recordable lines Y (step S305).

As a result, if the above conditions are satisfied,
The lower margin image data for Y / 2-Xi lines (that is, the line number obtained by subtracting the line number of the image data from the half line number of the recording paper) is added to the image data of the i-th page. (Step S306), right and left margin image data is added (step S307). Then, the image data of the (i + 1) th page is read and stored in the transmission buffer (step S308). next,
Similar to the i-th page, Y / 2-Xi + 1 lines for the image data of the (i + 1) -th page (that is, lines obtained by subtracting the number of lines of the image data from half the number of lines on the recording paper). The lower margin image data is added (step S309), and the left and right margin image data is added (step S310). The details of the lower margin image data addition processing and the left and right margin image data addition processing will be described later with reference to the flowcharts of FIGS. 4 and 5, respectively.

Next, the image data in the transmission buffer, that is, the image data of the i-th page and the (i + 1) th page (including the lower margin image data and the left and right margin image data) is set to 1
The image data for the page is transmitted (step S31).
1). Then, the page counter i is incremented by "2" (step S312), and the process returns to step S303.

When it is determined in step S305 that the above conditions are not satisfied, the left and right margin image data is added to the i-th page image data (step S313). Next, the image data in the transmission buffer, that is, the image data of the i-th page (including the left and right margin image data) is transmitted as image data for one page as usual (step S314). Then, the page counter i is incremented by "1" (step S31
5) and returns to step S303.

When it is determined in step S304 that the next page, that is, the (i + 1) th page is not accumulated, it means that the i page is the last page for one communication. Only the process of adding the left and right margin image data is performed on the image data of the page (step S316). Then, the image data of the i-th page (including the left and right margin image data) in the transmission buffer is transmitted (step S317), and the process ends.

Details of the lower margin image data addition processing in steps S306 and S309 will be described below with reference to the flowchart of FIG.

First, the number Z of lines of the lower margin image data in the ROM 2 designated by the operation of the keyboard 8 is set (step S401). Next, whether Y / 2−Xi = the number Z of lines of the lower margin image data related to the designation is added to the image data of the {(i + 1) th page,
Y / 2−Xi + 1 = whether or not it is the number Z of lines of the lower margin image data relating to the designation}, that is, the sum of the number of lines of the image data and the number Z of lines of the lower margin image data relating to the designation,
It is determined whether or not it is equal to 1/2 of the number of lines on the recording paper (recordable line number Y) (step S402).

As a result, if they are not equal, Y / 2-Xi
<Whether the number of lines of the lower margin image data according to the designation is Z or not {Y / 2−Xi + 1 when adding to the image data of page (i + 1) <the number of lines of the lower margin image data according to the designation Z or not}, that is, when the lower margin image data related to the designation is added as it is, the sum of the image data of the i-th page or (i + 1) th page and the lower margin image data is the line of the recording paper. It is determined whether or not it exceeds 1/2 of the number (recordable line number Y) (step S4).
03).

As a result, when the number of lines is over, the lower blank image data of the designated number Z of lines is read from the ROM 2 and reduced to (Y / 2-Xi) / Z image data ((i + 1) th page image data). To add, (Y / 2-Xi +
1) / Z reduction processing},
Alternatively, the sum of the image data of the (i + 1) th page and the lower margin image data is set to be equal to 1/2 of the number of lines on the recording paper (step S404). Then, the reduced lower margin image data is stored in the transmission buffer so as to be added (step S405), and the process ends.

On the other hand, if it does not exceed, the lower margin image data of the number of designated lines Z is read from the ROM 2 and added to the (Y / 2-Xi) / Z enlargement processing {(i + 1) page image data. If you do (Y / 2-Xi +
1) / Z enlargement processing},
Alternatively, the sum of the image data of the (i + 1) th page and the lower margin image data is set to be equal to 1/2 of the number of lines on the recording paper (step S406). Then, the enlarged lower margin image data is stored in the transmission buffer so as to be added (step S407), and the process is ended. When it is determined in step S402 that the sum of the number of lines of the image data and the number of lines Z of the lower margin image data related to the designation is equal to 1/2 of the number of lines of the recording paper (the number of recordable lines Y) Reads out the lower margin image data of the designated number of lines Z from the ROM 2 and stores it in the transmission buffer so as to add the lower margin image data that has been read out without performing reduction or enlargement processing (step S408), and ends. .

In any case, the main scanning length of the lower margin image data to be added is made to match the main scanning length W1 of the first page in the plurality of image data associated with the receipt number.

Next, in steps S307, S310,
The details of the left and right margin image data addition processing in S313 and S316 will be described with reference to the flowchart of FIG.

First, the main scan length WL of the left and right margin image data in the ROM 2 designated by the operation of the keyboard 8,
When WR is set (step S501) and the main scanning length Wi of the image data of the i-th page is added to the image data of the {(i + 1) th page, the main scanning length Wi of the image data of the (i + 1) th page Wi +1} is set (step S
502).

Next, the main scanning length Wi of the image data of the i-th page {When adding to the image data of the (i + 1) th page, the main scanning length Wi + 1 of the image data of the (i + 1) th page} Is equal to the main scanning length W1 of the image data of the first page (step S503). As a result, if they are not equal, the main scanning length Wi of the image data of the i-th page {If the image data is added to the image data of the (i + 1) th page, the main scanning length Wi + of the image data of the (i + 1) th page 1} is the main scanning length W1 of the image data of the first page
It is determined whether it is shorter (step S504).

As a result, when the length is short, the main scanning lengths WL, W
The left and right margin image data of R is read from the ROM 2, the total value of the main scanning lengths WL ′ and WR ′ after the addition of the left and right margin image data, and the main scanning length Wi of the image data of the i-th page Wi
{When adding to the image data of the (i + 1) th page, the main scanning length Wi of the image data of the (i + 1) th page
+1} and the main scanning length W1 of the image data of the first page are equal to each other, and the number of lines after the addition of the left and right margin image data is equal to the number of lines of the image data. The left and right margin image data is compressed or expanded (step S505). Then, the left and right margin image data are converted to the image data of the i-th page {(i +
1) When adding to the image data of the page,
It is stored in the transmission buffer so as to be added to the (i + 1) th page image data} (step S506), and the process is ended.

When the left and right margin image data are added, the main scanning lengths WL 'and WR' of the left and right margin image data after the addition may be different as shown in FIG. It may be.

On the other hand, when the main scanning length Wi of the image data of the i-th page is added to the image data of the (i + 1) th page, the main scanning length Wi + 1 of the image data of the (i + 1) th page is When it is longer than the main scanning length W1 of the image data of the first page, the image data of the i-th page from the transmission buffer {(i + 1) th page of the image data when the image data of the (i + 1) th page is processed. } Is read,
The number of lines of the image data is reduced so that the main scanning length Wi or Wi + 1 is kept equal to the main scanning length W1 of the image data of the first page ( In step S507), the data is stored in the transmission buffer (step S508), and the process ends.

In step S503, if the main scanning length Wi of the image data of the i-th page {(i + 1) th page image data is to be processed, the main scanning length Wi + 1 of the (i + 1) -th page image data is set. } Is determined to be equal to the main scanning length W1 of the image data of the first page, the processes of steps S504 to S508 are skipped and the process ends.

As described above, in this embodiment,
If two pages of image data to be transmitted can be recorded on one recording sheet on the receiving side, the image data for two pages is transmitted as one page of image data on the transmitting side. It is possible to reduce the running cost such that the margin portion of the paper can be reduced as much as possible, and it is not necessary to feed the paper extra for the margin portion, and recording can be performed quickly. Further, when the image data for two pages is transmitted as the image data for one page, the lower margin image data is added so that the image data of each page is recorded at the equally divided positions. The image data according to the above is easy to read, and the left and right margin image data is added so that the main scanning length matches the image data of the first page. Therefore, the blank portion is not mistaken as some information. .

The present invention is not limited to the above-mentioned form, and it is also possible to transmit image data of, for example, three pages or more as one page. Also, CC
It is possible to perform similar transmission control not only on image data read and input by a D scanner or the like but also on image data input by a computer or the like. Further, the addition processing of the lower margin image data and the left and right margin image data may be generated and added as needed without using the previously stored margin image data. Instead of reducing and adding the blank image data, the blank image data of the reduced size may be cut out and added.

Further, when a plurality of image data are combined and transmitted as described above, the main scanning lengths are made uniform, or the image data of each page is recorded at equally divided positions. It is also possible to perform only one of the processes. In addition, the image data serving as a reference when aligning the main scanning length is not the image data of the first page,
