If the ADRS is not the final address, that is, if the reading has not been completed up to the lower right position of the reading page in FIG. 12 (YES in S217), S2
At 18, the ADRS is incremented by 1 and the CPU 10
3 repeats the processing from S214. If ADRS is the last address (NO in S217), it is determined in S219 whether the next page exists. If the next page exists (YES in S219), the page number P is set in S220.
4 is added to the page, and if the next page does not exist (NO in S219), the initial value 1 is substituted for the page number Page in S221. After these processes, this subroutine ends.

FIGS. 12 and 13 are diagrams for supplementing the description of the flowchart of FIG. FIG. 12 is a schematic diagram showing addresses of the image memory 31 where print data is stored.

The image memory 31 stores the image data such that the upper left of the copy paper is the start address and the lower right of the copy paper is the last address. Further, as the address moves to the right side of the copy sheet, the address increases by one. When the address reaches the right end, the line feed starts with the increase of the address and the image data is stored so as to move to the left end of the copy sheet.

The page print area is provided between the start address and the end address of the image data, and a page number is printed on a copy sheet at a position corresponding to the page print area.

FIG. 13 is a diagram showing an example of font data stored in the font ROM 35.

The font for one character composed of 8 × 8 dots is converted into a hexadecimal number in units of one line arranged horizontally. One character is constituted by arranging those numerical values vertically in eight columns. These are taken in as addresses in the page print area of the image memory 31 as print data and are printed.

FIG. 14 is a diagram showing the correspondence between a copy obtained when the page printing mode and the 4-in-1 copy mode are simultaneously selected and copied in the copying machine 1, and the original. Copies 309 and 310 are output according to the input originals 301 to 308. The copy 309 is the first copy and the page number is 1. In addition, the originals of the first to fourth pages are output side by side in the upper left, upper right, lower left, lower right of the sheet, respectively. Copy 310
This is the second copy, and the page number is 5. Also,
For this, the originals of the fifth to eighth pages are output side by side at the upper left, upper right, lower left, and lower right of the sheet, respectively.

Similarly, the page number (4n-3) (n = 3, 4, 5,...) Is printed on the nth copy. In this case, the originals of the pages (4n-3) to (4n) are output side by side at the upper left, upper right, lower left, and lower right of the sheet, respectively.

With the processing by the CPUs 101 and 103 as described above, the copying machine 1 outputs the data on one copy.
Only the smallest page number of the original on the front side is printed as data specifying the order of output copies.
As a result, the correspondence between each document and the output document image is clear, and the page numbers can be added so that the output image is easy to read.

Note that the image processing apparatus according to the present invention is not limited to the copying machine in the above-described embodiment.
Various changes can be made within the scope of the gist.

For example, the configurations of the optical system 60, the image forming system 70, and the sheet conveying system 80 are arbitrary. In particular, as an image print head, besides a laser beam scanning optical system, a liquid crystal
An optical shutter element using LZT may be used, or an image may be formed on a photoconductor.

Further, for example, the image processing apparatus may be a facsimile transceiver.
