FIG. 3 is a block diagram showing the configuration of this system. In this embodiment, the mode for sorting is selected using the operation section A. There is a mode for setting the number of copies to be made, and a mode for setting a pattern to serve as a mark for sorting and a position to attach the pattern. If this pattern and pattern position are not specified, the pattern written in memory B in advance will be output.

The set number of copies is written as a counter in the memory B, and is counted down each time a plurality of originals on the automatic document feeder C complete one cycle. As the countdown progresses, the central processing unit (CPU) D reads out the pattern in the memory B, combines it with the analog image of the document, and outputs it. The automatic document feeder C continues to feed the document until the set number of copies are completed.

FIG. 4 shows the flowchart of this embodiment. In the 0-paper flowchart, if the sorting mode is selected, even if the set number of copies is 1, the first or last document on the document feeder will be placed on the copy paper. The sorting pattern shall be copied.

FIG. 5 shows the state of copies and printed sheets that have been discharged from the paper discharge section and sorted.

The sorting mode can be used at the same time as the conventional combining mode for multiplex/compound copying, and the sorting mode for multiple copying is the one used for this purpose.

If you do not want to combine the colors or patterns for sorting on some of your printouts, add an extra sheet of paper to the top or bottom of multiple documents on the automatic document feeder, and then By combining the colors or patterns for sorting in the mode, the same results as in the case of using special paper for conventional sorting can be obtained. Further, by doing so, there is an advantage that sorting does not require special paper, and sorting of different sizes does not require paper either.

Trap 5 ■ 1 When automatically feeding documents of different sizes, it is possible to handle different sizes of documents by specifying at which position on the document the sorting pattern is to be attached.

East] 1 Eoka Oka The top or bottom document placed on the automatic document feeder is sorted by combining patterns that serve as marks for use, so the paper periphery is stored as a pre-memorized pattern. 4
It is also possible to add a border or pattern to the sides to create a cover.

[Effects of the Invention] As explained above, according to the present invention, by copying a color or pattern for sorting onto a part of the recording material, sorting can be easily performed without installing an automatic sorter. It becomes like this. This also reduces the cost of automatic sorters.

In addition, the present invention enables sorting without the need for conventional partition paper or operator involvement.
Sorting efficiency is greatly improved.

In addition, even if there is only one size of output paper, marks can be added for sorting, so partition paper of different sizes is not necessary.

Moreover, according to the present invention, even when mixed documents are loaded, the position of the sort can be determined at a glance by specifying the printing position of the partition mark.
