Filed: 1985-10-07
Abstract: PURPOSE:To improve efficiency of copying by indicating an original area that can be formed on selected recording paper when recording paper that does not conform to the original size detected by an original size detecting means. CONSTITUTION:When a copy key is depressed, an original is set on an original platen 13 by an automatic original feeding device, and at the same time, the size of the original is detected by an original size detecting means 12a, and the size is decided by a CPU.

As the result, a cassette that contains recording paper P corresponding to the original size detected by the means 12a is not mounted, an original area that can be formed on the selected recording paper is displayed on a display device. Thus, an operator can judge by himself whether the direction of the original or the recording paper P is to be changed or copying is to be suspended. Accordingly, the operator can proceed to after processing quickly, and the efficiency of copying can be improved.
