ABSTRACT:
A copier has an operating mode in which copying is performed upon closing the cover of a platen and use is made of the size of an original to copy the original. An example is a mode in which the image of an original is divided up into a plurality of blocks and the images of the respective blocks are enlarged and each is copied on a separate sheet of copy paper. In such a scenario, it is determined whether the size of the original is capable of being sensed by sensors. If it is determined that sensing is not possible, processing for inferring the shape of the original is executed. In accordance with this processing, the size and orientation of the copy paper as well as the currently prevailing copying mode are checked, then the size and orientation of the original are inferred based upon the results of the check. Even if the size of the original is cannot be sensed, therefore, it is possible to infer the size and execute copying accordingly.
