Abstract
An electrophotographic copying machine including a copy enabling device, a mode switch, a detection device, and a control device. The mode switch is actuated to select a dual copy mode for copying at least two parts of a single document on one or more copy papers. The detection device is responsive to the mode switch for detecting whether the size of a copy paper to be used is within a predetermined range, for example, about half or less than the maximum size of a document to be disposed on a document table. The control device is responsive to the detection device for controlling execution of the dual copy mode.
