BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image information recording apparatus suitable for application to a facsimile machine or the like.

[0002]

BACKGROUND OF THE INVENTION In a facsimile machine which uses cut sheets as recording sheets, three kinds of recording processes as shown in FIG. 9 are performed according to the length of received image information. That is, when the length L of the image information G is shorter than the recording area length K1 of the recording paper K as shown in FIG. 7A, the image information G is printed out as it is. When the image information length L is longer than the recording area length K1 and shorter than the page division threshold value K2 as shown in FIG. 8B, the image information length L is reduced at an appropriate reduction ratio before being printed out. Further, when the image information length L exceeds the page division threshold value K2 as shown in FIG. 7C, the image information G is divided and printed out on a plurality of recording sheets K. In this case, it is normally not reduced.

[0003]

When the image information G is divided and recorded by the above-mentioned facsimile apparatus, it is general to divide the image information G at a position corresponding to the recording area length K1 as shown in FIG. Therefore, in some cases, effective image information G such as characters and pictures may be divided from the middle. In this way, when characters etc. are divided in the middle,
It is difficult to determine this, and the determination may be erroneous.

Therefore, the present invention solves the above-mentioned problems, and proposes an image information recording apparatus capable of preventing the image information from being divided in the middle when the image information is divided and recorded. To do.

[0005]

In order to solve the above-mentioned problems, in the present invention, an image information length detecting means for detecting the length of input image information, an image information length and a recording area length of a recording paper are provided. When the division recording determination means for comparing and determining whether to perform division recording and the division recording determination means determines that division recording is performed, the margin portion in front of the position corresponding to the end of the recording area of the image information is displayed. A margin portion detecting means for detecting, an image information dividing means for dividing the image information based on an output from the margin portion detecting means; and a recording means for printing out the divided image information on a recording paper. To do.

Further, in the present invention, the image information length detecting means for detecting the length of the input image information is compared with the image information length and the recording area length of the recording paper to judge whether or not division recording is performed. Division recording determining means, and a margin portion detecting means for detecting a margin portion before a position corresponding to the end of the recording area of the image information when the division recording determining means determines that the division recording is performed, and a margin portion detecting means. The image information dividing means for dividing the image information based on the output of the image information and the recording means for printing the divided image information on the recording paper are provided. It is characterized in that the printout is duplicated over the pages.

[0007]

In FIG. 1, the image information G received by the receiving means 1
(FIG. 9) is stored in the storage means 2 and is supplied to the image information length detection means 3 for one page to detect the length L of the image information G. Next, the image information length L is supplied to the divided recording determination means 4, where the recording area length K of the recording paper K is as in the conventional case.
1 and whether to print out as it is (Fig. 9
(A)), reduction (FIG. 9 (b)), or divided printout (FIG. 9 (c)).

If it is judged that the divided recording is to be performed, the margin information detecting means 5 then outputs the image information G as shown in FIG.
A margin portion detection area A is set above the position B corresponding to the end of the recording area and it is determined whether or not there is a margin portion. Here, as shown in FIG. 8, the line pointer set at the bottom edge line of the margin detection area A is decremented line by line to find the number of black pixels in the line with the line pointer, and this is the margin determination threshold S. When it is smaller, this line is determined as a blank area.

When there is a blank area in the blank area detection area A, the image information dividing means 6 divides the image information G from the blank area as shown in FIG. Will be printed out. Image information G
It is prevented that the effective image information of is divided from the middle. When there is no blank area, for example, the blank area detection area A is double printed out on the previous page and the subsequent page after division as shown in FIG. As a result, it is possible to prevent the valid image information from being divided from the middle and being erroneously determined.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment in which the image information recording apparatus according to the present invention is applied to a facsimile machine will be described in detail with reference to the drawings.

FIG. 1 shows a functional block of a facsimile apparatus to which the image information recording apparatus of the present invention is applied. 1 in the figure
Is a receiving means, which is connected to the communication line and receives the image information transmitted from the other party. A storage unit 2 stores the received image information. 3 is an image information length detecting means,
The length of one page of the received image information is detected.

Reference numeral 4 denotes a division recording determination means, which is the same as shown in FIG. 9 when the image information length L is less than or equal to the recording area length K1, and the image information length L is longer than the recording area length K1 and the page division threshold is set. If the value is less than or equal to K2, it is determined to be reduced, and if the image information length L exceeds the page division threshold value K2, it is determined to be divided. The recording area length K1 is input in advance.

Numeral 5 is a margin portion detecting means, which detects a margin portion by searching a predetermined range immediately before the division position by a method described later when it is judged that the image information is divided and recorded. Image information dividing means 6 divides the image information based on the output of the margin portion detecting means 5. That is, when the blank space detection means 5 detects a blank space, the image information is divided from this blank space. If no blank area is detected, the image is divided at a position corresponding to the end of the recording area length K1, and the image information of the blank area detection area is output to the subsequent page immediately before the division position. A recording unit 7 prints out the divided image information on a plurality of recording sheets.

Reference numeral 8 denotes a reduction ratio calculating means, which calculates the reduction ratio by dividing the recording area length K1 by the image information length L when the division recording determining means 4 determines to reduce the image information. If it is determined that the image information is left as it is, the reduction rate is 100%. Reference numeral 9 denotes a reduction means, which reduces the image information at the calculated reduction rate. The reduced image information is printed out on the recording paper by the recording means 7.

FIG. 2 shows the system of this facsimile machine. In the figure, 11 is a CPU that manages transmission / reception control,
A program ROM 12 stores various control programs such as a transmission / reception program, and a RAM 13 stores image information to be transmitted. The image information read by the image reading unit 14 is read via the interface 15 as R
After being stored in the AM 13 or directly, it is supplied to a modem and a network control circuit (NCU) 16 which functions as a transmitting / receiving means.

The image information input from the communication line is stored in the RAM 13 via the modem and the NCU 16 or is directly supplied to the recording unit 18 functioning as a printer via the interface 17 to record the content. It The telephone number of the transmission destination is displayed by being supplied to the display unit 20 via the interface 19.

The operation unit 21 is provided with a plurality of keys (not shown), and when these keys are operated, the contents thereof are taken into the CPU 11 via the interface 22. Each of the above-mentioned means is achieved by the CPU 11 operating according to the control program.

FIG. 3 is a flow chart showing the procedure of the printout processing 30 in this facsimile apparatus. First, the image information length L is compared with the page division threshold value K2 (step 31). If the image information length L is longer,
Next, as shown in FIG. 4, the detection area A of the margin is set (step 32). The blank area detection area A is set to a predetermined length immediately before the recording area end equivalent position B of the image information G.

Next, a blank area detection process is performed in the blank area detection area A (step 33). Details of this processing will be described later. Next, it is judged whether or not there is a blank portion in the blank portion detection area A (step 34). If there is a blank portion, then the blank portion is determined as a page dividing position as shown in FIG. Performed (steps 35-3)
6). The divided image information is printed out on the plurality of recording sheets K by the recording unit 18 (step 37), and the printout process 30 is completed.

If it is determined in step 34 that there is no margin, the position B corresponding to the end of the recording area is determined as the division position and the image information is divided (steps 38 to 39), as shown in FIG. Then, double output of the blank area detection area A is performed (step 40). That is, in this case, the previous page after division is output from the leading end of the image information G to the division position, and then the subsequent page is output from the upper end of the margin detection area A to the last or next division position of the image information G, This is printed out on the recording paper K in step 37, and the printout processing 30 ends.

That is, in this case, the blank area detection area A
Image information G is printed out twice over the preceding and following pages. This makes it possible to prevent the image information G from being divided in the middle and being erroneously determined.

When it is determined in step 31 that the image information length L is shorter than the page division threshold value K2, the reduction ratio is calculated and the image information reduction process is performed (step 41).
42), the image information reduced here is printed out at step 37, and the printout process 30 ends.

FIG. 7 is a flow chart showing the procedure of the blank space detection processing 50 performed in step 33 described above.
The margin detection process 50 will be described below with reference to FIG. First, the line pointer is set to the line at the position B corresponding to the end of the recording area of the image information G (step 5
1) Then, the end pointer is set to the leading line of the blank area detection area A (step 52).

Subsequently, the number of black pixels of the line in which the line pointer is set is calculated, set in the table of the RAM 13 (step 53), and then the line pointer is decremented (step 54). Next, it is judged whether or not the line pointer has crossed the end pointer (step 55). If it is judged that the line pointer has not crossed the end pointer, the number of black pixels of the line with the line pointer is calculated in step 53, and the same as the above. Processing is performed.

When it is determined in step 55 that the line pointer has exceeded the end pointer, the line pointer is next reset to the position B corresponding to the end of the recording area (step 56), and then the accumulator is reset to "0". (Step 57). Next, the number of black pixels of the line having the line pointer is read from the RAM 13 and set in the accumulator (step 58).

Subsequently, it is judged whether or not the value of the accumulator is equal to or more than the margin judgment threshold S (step 59). If it is judged here that it is smaller than the margin judgment threshold S, then the line pointer is next. It is determined that the line with "" is a blank portion (step 60), and the blank portion detection processing 50 ends.

If it is determined in step 59 that the value of the accumulator is greater than or equal to the blank space determination threshold value S, the line pointer is decremented (step 6).
1). Next, it is judged whether or not the line pointer has crossed the end pointer (step 62). If it is judged that the line pointer has not crossed the end pointer, then in step 57 the accumulator is reset to "0", and the above-mentioned steps are carried out. Processing similar to is performed.

When it is determined in step 62 that the line pointer has crossed the end pointer, it is next determined that there is no margin in the margin detection area A of the image information G (step 63). Margin detection processing 5
0 ends.
