AUTOMATIC DOCUMENT FEEDER AND METHOD FOR THE FEEDER

摘要

PURPOSE: To automatically feed a document of twofold size of a document size which is regulated by the size of a platen glass on the platen glass. CONSTITUTION: This feeder automatically feeds the document to an electrophotographic device constituted so that the document placed on the platen glass PG on which the document of the specified size is placed so as to cover an almost entire surface is read and scanned along the longitudinal direction of the platen glass PG. The feeder is equipped with a carrying mechanism 26 carrying the document in a direction orthogonal to the longitudinal direction of the platen glass PG and feeding it to the platen glass PG, and a control unit not shown in figure and controlling so that the first half part of the document of twofold size may be fed onto the platen glass PG by driving the carrying mechanism 26 in the case of the document is twofold size of specified size. Then the later half part of the document of twofold size is fed to the platen glass PG by driving the carrying mechanism 26 after finishing image reading operation for the first half part.
