The present invention relates to a control device for a copying machine having a so-called cover function, in which the image data is copied on special paper such as letter head paper, color paper, and thick paper.

[Conventional technology]

In the above-described copying machine, special paper is stored in any one of the plurality of paper feed trays, and when the first and last pages of the original are selected, this paper feed tray is selected and the other papers are selected. At the time of copying, another paper feed tray, that is, a paper feed tray containing plain paper is automatically selected.

When the cover function is selected, special paper and plain paper on which a series of copying operations are performed must be the same size.

[Problems to be solved by the invention]

However, conventionally, when the paper size of the currently selected paper feed tray is different from the special paper used for the cover, it is common to prohibit the copying operation, in which case the operator removes the paper in the paper feed tray. It has to be replaced or another paper feeder must be selected again, and there is a problem that copying efficiency and operability are poor.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a copying machine control device capable of improving the copying efficiency and the operability of an operator when a cover function (cover mode) is designated.

[Means for solving the problem]

The object is to select one of a plurality of paper feed trays capable of storing paper of an arbitrary size, copy only the first page, the last page, etc. of the original on special paper stored therein, In a copier control device which has a cover function for selecting another sheet feeder and copying it to plain paper stored in the page, and in which the cover function can be arbitrarily selected, a cover function is provided. If the paper size of the currently selected paper source and the special paper size are different when is selected, the paper source that automatically selects another paper source that contains paper of the same size as the special paper This is achieved by providing selection means.

[Action]

If the currently selected paper size is different from the size of the special paper used for the cover, the paper feed tray selecting means automatically selects a paper feed tray containing the same size paper, and furthermore, a plurality of papers of the same size. If so, the one with the larger number of stored sheets is automatically selected.
