Abstract

PROBLEM TO BE SOLVED: To facilitate filing by detecting the size of the largest sheet out of two or more sheet-like originals and reading out all the sheets of the original set by the detected size. SOLUTION: An original set consisting of one or plural sheets is put on an original feed tray 32 of an ADF and set up on the center of the tray 32 by moving regulating plates 30L, 30R. After depressing a key for specifying the reading of all sheets by the maximum size of sheets of the original set, a start key is depressed. Consequently each original sheet is entered into a guide mechanism 34 and read out through an ADF type translucent plate 23. Namely a CPU detects the maximum size of a set of original sheets set up on the tray 32 and fixes the reading size of the originals to the detected size. Then the CPU starts the ADF to read out all the sheets of the original set by the size detected by a sensor S1.
