Abstract: The present invention is a type of office automation machine that is capable of copying a large size drawing by using an electronic photo method. The invention is designed to provide general printing function, a standard copying function, and a function of copying large size manuscripts such as design drawings. These functions are made possible by using a continuous printing paper in a reel form and by severing and discharging print output by an appropriate length. The printing paper is designed to refilled by a removable cassette. The transporting blades orbitally rotate to retrieve the developing agent from its container, so that the copying machine can be used efficiently and economically.
