copying device

Abstract

Abstract PURPOSE:To improve copying efficiency by juxtaposing one unit of documents in a specific position on a contact glass, receiving a signal from detecting member and stopping the drive of an automatic document feeder, and driving an optical scanner and an automatic transfer paper feeder. CONSTITUTION:Plural documents 4 are fed as one unit from the automatic document feeder 2, and are juxtaposed in their feeding direction in the specific position on the contact glass 28; there are detected by the detecting members 23 and 25-27. On receiving the detection signal from the detecting members, the automatic document feeder is stopped driving, and then the optical scanner 40 and the automatic transfer paper feeder 42 are driven. As a result, the scanner 40 is moved to succeedingly expose the plural juxtaposed documents. The automatic transfer paper feeder 42 succeedingly feeds transfer paper in number the same as the documents 4 to the position corresponding to the documents 4, which are copied. Copying efficiency is thus improved.
