Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image forming apparatus used as, for example, a digital copying machine, and in particular, an original set on an original table and an original stored in a memory are printed in a designated page order. The present invention relates to an image forming apparatus.

[0002]

2. Description of the Related Art Generally, in a digital copying machine, image data obtained by reading with an image sensor such as a CCD can be stored (or stored) in a memory. Image data read from the original document (one original set) is stored in a memory, and the image data is read from the memory to copy (or print) a required number of images onto a sheet when necessary. So-called memory mode copying is possible (Japanese Patent Laid-Open No. 3-97372).

Further, there are provided a memory mode in which image data stored in a memory is read and copied onto a sheet, and a direct mode in which image data read from a document is directly copied onto a sheet, and these modes are synchronized. There is also proposed a copying machine which synthesizes an image on one sheet and makes a copy (JP-A-60-114080).

[0004]

However, in any of the conventional copying machines described above, for example, when copying a plurality of manuscript sets including common manuscripts as materials to be distributed to attendees of a conference, There is a problem that the document must be read many times even though it is a common manuscript.

That is, for example, the number of pages is a, b,
If there are three types of document sets A, B, and C consisting of the document c, and the documents for specific m pages are common to each other, copy 1 of these document sets
It was necessary to perform (a + b + c) readings in order to obtain copies. At this time, for each of the common m pages of originals, the same content must be read three times, and (m × 2) times are eventually wasted.

Further, for example, when there is a document set D having a page number d, and there is a document set E different only in the x-th page and a document set F different in only the y-th page, those document sets In order to obtain one copy, it was necessary to perform (d × 3) readings in the same manner as described above, although the pages having different contents were only two pages and most of them were the same.

In order to eliminate such waste, each original set is sorted into a common original and a non-common original, a common original is subjected to multi-copy three times by one reading, and a non-common original is respectively separated. 1
It is conceivable to make the copies one by one and rearrange and insert the sheets so that the copies are prepared for each document set after the entire copy is completed.

However, in this case, it takes a lot of time and labor to rearrange the sheets after copying, and there is a problem that a place for the work must be secured.
In particular, when the common part is different depending on the document set, it is easy to make a mistake in the order of the sheets and the insertion position, which puts a lot of burden on the operator.

In view of the above problems, the present invention eliminates the need to read the common document many times when copying a plurality of document sets having a common document, and rearranges or inserts sheets after copying. It is an object of the present invention to provide an image forming apparatus that does not need to perform.
