DOCUMENT SIZE DETECTION DEVICE

摘要

PROBLEM TO BE SOLVED: To reduce the probability of erroneous detection of a document size detection device caused by an operation habit of a user, as a result of switching a document cover to an automatic document feeder from a platen cover. SOLUTION: The document size detection device uses an opening/closing detection means for outputting a continuous value matching an angle at which the document cover is opened/closed. Based upon the output of the opening/closing detection means, a document size judgement means judges a document size. COPYRIGHT: (C)2006,JPO&NCIPI
