When different sizes of documents are set, the max. size is detected. Th e do cum ent wi dth is det ecte d by the doc ume nt w idth s ensors (W1, W2, W3), and the document length is detected by the document length s ensors (L1, L2 ) t o i dentify the docum ent size. Judg em ent of the docume nt size is made in a certain t iming after detecting the document with the document set sensor (W0).
