ABSTRACT:
A copying apparatus includes a copy paper cutting device which is operated when an original document or an optical device for exposure reaches a predetermined position. The original document or the optical device is stopped when a trailing edge of a copy paper is detected. After at least the leading edge of the copy paper passes through the copy paper cutting device, the copy paper is fed out entirely from an apparatus frame without operating the copy paper cutting device. This results in that the last copy paper sheet of the roll of copy paper is not shorter than the distance between transport rollers in the copy paper passageway to prevent a copy paper jam.
