Abstract

PURPOSE:To execute recording so that image data can be put into one sheet of cut paper by thinning out the number of residual lines at an equal interval from a main scanning line of the image data, in the case a white line is thinned out in accordance with a prescribed condition and the number of thinned-out white lines is less than a calculated difference number. CONSTITUTION:A count value of a page line counting means 12 is compared with the number of main scanning lines stored in a storage means 4, by which whether received image dat of a l-page portion can be recorded into one sheet of cut paper or not is discriminated. Subsequently, in the case the number of lines exceeding the number of main scanning lines which can be recorded into one sheet of cut paper is below a numerical value determined in advance, first of all, a white line is thinned out. The white line is thinned out under the prescribed condition, for instance, such as one piece per two pieces of white lines. In the case thinning-out is insufficient, the main scanning line of the image data is thinned out at an equal interval. In such a way, the number of main scanning lines of the image data after being thinned out becomes the number of main scanning lines which can be recorded into one sheet of cut paper.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a facsimile machine that uses cut paper of regular size as recording paper.

<Prior Art> In conventional facsimile machines that use cut sheets as recording paper, when the received image data for one page exceeds the amount that can be recorded on one sheet of cut paper, the image data in the excess portion is It is now recorded on the next cut sheet.

However, most cases where one page of received image data cannot be recorded on one cut sheet are, for example, when the length of the original document sheet on the sending side is a little longer than the specified size. In such a case, the received 1
When image data for a page is recorded on two sheets of cut paper, the second cut sheet is almost blank, resulting in a disadvantage that the cut sheets are wasted. Also, for example 2
If even a small amount of image is recorded on the second cut sheet, the second cut sheet cannot be thrown away, so in the end, it is necessary to check the received data across two sheets. Another drawback was that it was difficult to handle.

Therefore, in order to eliminate such drawbacks, Japanese Patent Application Laid-open No. 1-
Publication No. 130662 states that when the received image data for one page has the number of lines exceeding the number of main scanning lines that can be recorded on one sheet of cut paper, and the number of lines exceeding the number is below a certain value, , a facsimile apparatus has been proposed that does not record received data beyond this range.

In addition, in Japanese Patent Application Laid-open No. 1-137880, the received 1
When the image data for a page has more lines than the number of main scanning lines that can be recorded on one cut sheet,
A facsimile apparatus has been proposed in which, when the data to be recorded on the second cut sheet is completely white data, the data is not recorded.

<Problems to be Solved by the Invention> Among the facsimile machines described in each of the above-mentioned publications, in the former, even if there is a line that includes an image among the lines that cannot be recorded on a single sheet of cut paper, the number of lines cannot be recorded. If it is less than a certain value, it will not be recorded, so if relatively important data is included in the line that is not recorded, this may cause problems.

On the other hand, the latter type of facsimile machine does not have such a drawback, but if the data to be recorded on the second cut sheet is not all white, that is, if it contains even a small amount of black data, the image data may be Recording is performed on two sheets of cut paper, and the disadvantage that handling of the recording paper is inconvenient remains unresolved.

This invention was made based on this background, and is applicable when the received image data for one page exceeds the amount of data that can be recorded on one sheet of recording paper, and when the second cut sheet is To provide a facsimile device capable of satisfactorily recording received image data on one sheet of cut paper without worrying about data loss when there is little data to be recorded.

Means for Solving the Problems> The present invention provides a facsimile machine that uses cut paper of standard size as recording paper, and a page line counting means for counting the number of main scanning lines of one page of received image data. , an own line detection means for detecting a white line in which all pixels are white among the main scanning lines of one page of received image data; and a white line count for counting the number of white lines detected by the own line detection means. means, a storage means in which the number of main scanning lines that can be stored on one sheet of cut paper is stored in advance, and a count value of the page line count means is compared with the number of lines stored in the storage means to calculate the difference, and the number of lines stored in the storage means is calculated. A discrimination means for discriminating that the count value of the line count means is greater than the number of stored lines and the difference is less than or equal to a predetermined value; A white line deletion means thins out white lines that have been thinned out according to predetermined conditions, and when the number of white lines thinned out by the white line deletion means is less than the calculated difference number, the remaining number of lines is removed from the main scanning line of the image data. The facsimile apparatus is characterized in that it includes a second line deletion means for thinning out lines at intervals, and a recording means for recording the image data thinned out by the line deletion means on one sheet of cut paper.

Function> By comparing the count value of the page line counting means with the number of main scanning lines stored in the storage means, it is determined whether the received image data for one page can be recorded on one sheet of cut paper. A determination will be made. If it is not possible to record on one sheet of paper, and the number of lines exceeding the number of main scanning lines that can be recorded on one sheet of paper is less than a predetermined value, first, the white line is I am drawn to it.

Own line is under certain conditions, for example, 1 for every 2 white lines.
It is thinned out like a book. Then, when the number of thinned white lines reaches the calculated excess line, the thinning ends. If all the white lines are thinned out under the above conditions but thinning is not sufficient, the main scanning lines of the image data are thinned out at equal intervals.

Therefore, the number of main scanning lines of the thinned image data is the number of main scanning lines that can be recorded on one sheet of cut paper.

Furthermore, since the white lines are thinned out and the lines are further thinned out at equal intervals, the image data recorded on the cut paper is almost never missing or distorted when viewed with the naked eye.

FIG. 1 is a block diagram showing the main structure of this embodiment, showing the detailed structure of the recording control section 11 and the flow of received image data.

The recording control section 1l includes a page line counter 12, an own line detection circuit 13, a white line counter 14, a comparison/calculation section 15, and a recording operation control section 16.

The received image data is applied to the page line counter 12, white line detection circuit 13, and page memory 4 in units of pages. Page line counter 12
Then, the number of main scanning lines of the received image data for one page is counted. The white line detection circuit 13 detects a white line in which all pixels are white among the main scanning lines of the received image data for one page. In addition, at this time, it is preferable to be able to detect the appearance of the white line, that is, the white line pattern, which is how many consecutive white lines and how many consecutive lines other than white lines. A white line counter 14 counts the number of white lines detected by the white line detection circuit 13. The comparison/calculation section 15 outputs the output of the page line counter 12 and the white line counter 14.
It performs a predetermined process based on the output of , and the number of lines that can be recorded on the cut paper, and provides a control signal to the recording operation control section 16 .

Further, the image data that has been applied to the page memory 4 and temporarily stored is applied to the recording unit 3 via the recording operation control unit 16 and is recorded on a cut sheet.

In this embodiment, the recording control section 11 is divided into components such as a page line counter 12, a white line detection circuit 13, a white line counter 14, a comparison/calculation section 15, and a recording operation control section 16. If the entire control section 1 is configured with a microcomputer, the above-mentioned specific circuits and the like do not exist individually, and these processes are accomplished by software.

FIG. 3 is a flow chart showing the recording operation of the facsimile machine according to this embodiment. Next, the recording operation of this apparatus will be explained in accordance with the flow shown in FIG. 3 and mainly referring to FIG.

When the image data is received by the facsimile machine (
Step S1), the received image data is first stored in the memory 8.
(Step S2).

Next, one page of image data is retrieved from the image data stored in the memory 8 (step S3), and the retrieved one page of image data is decoded (step S4).
, the decoded image data for one page is stored in the page memory 4.
(step S5).

Further, as described above, the decoded image data for one page is given to the page line counter 12, and the number A of main scanning lines of the image data for one page is counted by the page line counter 12 (step S6 ).

Further, the decoded image data for one page is given to the own line detection circuit 13, and it is determined for each main scanning line whether or not it is a white line in which all pixels are white pixels, and when a white line is detected, The white line counter 14 counts the number B of its own lines (step S7).

Next, the comparison/calculation unit 15 compares the number A of main scanning lines of the received image data for one page with the predetermined number C of main scanning lines that can be recorded on one cut sheet, and calculates the difference D. -A-C is calculated (step S8).

Note that the number C of main scanning lines that can be recorded on one sheet of cut paper is calculated based on the size signal of the cut paper detected by the sensor section 6 (see FIG. 2), which is given to the control section 1.
The corresponding number C of main scanning lines is read from the memory 8 and provided to the comparison/calculation section 15 .

Next, the comparison/calculation unit 15 determines whether "D≦o" (step S9), and if rD≦0, that is, the number of main scanning lines A of the received image data for one page.
is smaller than or equal to the number C of main scanning lines that can be recorded on one cut sheet, the recording operation control unit 16
All lines A of the page memory 4 are controlled to be provided to the recording section 3 (step S10).

Then, it is determined whether it is the last page or not (step S1
9) If it is not the last page, the process from step S3 is repeated.

In step S9, if D≦0, if there is a line that completely exceeds the record line of the epage,
Next, it is determined whether or not the resolution is high (step S11).
). For example, when a facsimile device receives image data in standard mode, it determines that the resolution is not high resolution, and in this case, it first scans the main scanning line out of the number A of main scanning lines of the received image data for one page. number C
is given to the recording section 3, and recorded on one cut sheet (step S12).Then, the remaining main scanning line number D is given to the recording section 3, and it is recorded on one cut sheet (step S12). It is recorded on paper (step S13).

Then, it is determined whether it is the last page or not (step S1
9) If it is not the last page, the process from step S3 is repeated.

In step Sll, if it is determined that the resolution is high, then the overline number D is set to "D≦0.05".
It is determined whether or not it is XCJ (step S14). That is, it is determined whether the number D of recording overlines is less than or equal to a predetermined value.

If the above formula is not satisfied, the main scanning line number C out of the main scanning line number A of the received image data for one page is first given to the recording unit 3, and then is recorded on one sheet of cut paper (step S12).
Then, the remaining main scanning line number D is given to the recording section 3, and is recorded on the second cut sheet (step S
13).

Then, it is determined whether it is the last page or not (step 51).
9) If it is not the last page, the process from step S3 is repeated.

If it is determined in step S14 that "D≦0.05 are compared, and the recording overline number D
It is determined whether or not the number B is less than or equal to one-half of the number B of white lines.

If it is determined as "D B/2", the received image data for one page is thinned out by one line for each B/D line in the recording operation control unit 16. When the number C of main scanning lines that can be recorded on one cut sheet is given to the recording unit 3 (step S16), the output process is ended (step S18).

On the other hand, if it is determined in step S15 that rD<B/2J is not true, the white lines are thinned out line by line,
And the lines other than the white line are ((A-B)/(D
-B/2)) One line is thinned out for each line (step S17). Then, when the number C of main scanning lines that can be recorded on one cut sheet is given, the output process is ended (step S18).

If it is determined in step S19 that the page is not the last page, the processing from step S3 is repeated.

In the above embodiment, the entire received image data is temporarily stored in the memory 8, but the image data is not stored in the memory 8, and each time one page of image data is received, It may be decoded and stored in the page memory 4.

Note that the cut paper may be so-called plain paper, or may be thermal paper or photosensitive paper.

Further, step Sll in the above embodiment may be omitted.

Effects of the Invention> The present invention is configured as described above, and when the received image data for one page is slightly larger than the amount of data that can be recorded on one sheet of paper, the white line portion is After the white line of the own line part is thinned out appropriately, or the white line is thinned out preferentially, all lines are thinned out evenly, and the image data is fit on one sheet of cut paper. Since the received data is recorded in such a manner, handling of the recorded received data is convenient, and it is possible to prevent the occurrence of cut sheets with large margins and on which only a small amount of data is recorded.
