Abstract
A multi-mode copying apparatus includes a contact glass on which an original is placed facing downward, a scanning unit for scanning along the contact glass, a photosensitive drum, imaging unit for forming a copy image on the drum, at least one cassette for storing therein a quantity of copy sheets, a size detector for detecting the length of the copy sheets stored in the cassette, and a control system for controlling the operation of the apparatus in accordance with the length information detected by the size detector. In one mode of operation, the control system divides the original surface into two original surface sections, i.e., left and right half sections, based on the length information supplied from the size detector, and copies are produced from at least one of the left and right half sections using a home position of the scanning unit as a reference for each copying operation.
