Claims

[Scope of utility model registration request]

In a copying machine in which a light-shielding sheet defines an area corresponding to a document to be copied on a platen, means for detecting the size of a document by using movement of the light-shielding sheet, and a document whose size is detected. 1. A control device for a copying machine, comprising means for determining the set orientation of a document on a platen, and means for issuing a warning when the set orientation of the document is not compatible based on the output of the determining means.
