ABSTRACT:
An electrophotographic copying machine of an automatic magnification/reduction-controllable type comprises a measurement circuit, a comparison circuit, and a display. The measurement circuit is provided for measuring the lengths of a copy document along its horizontal side and a vertical side. The comparison circuit compares the length of the horizontal side with that of the vertical side. The display displays either a first type of copy paper suitable for longitudinal feed when the length of the horizontal side is longer than that of the vertical side or a second type of copy paper when the length of the horizontal side is shorter than that of the vertical side.
