ABSTRACT:
A copying apparatus is provided which makes collated duplex copies from the duplex original documents, first one side is copied by a necessary number of sheet, and then the other side is copied. The originals are put on a recirculating automatic document feeder with one side faced down, and are directly sent into the exposure region in the same face-back relation when copying the first set, and are inverted after exposure and returned. When copying the second and subsequent sets, the originals are inverted and conveyed into the exposure region, and are inverted after exposure and returned. When copying the final set, the originals are inverted and conveyed into the exposure region, and are directly returned in the same face-back relation, so that they are stacked up with the other side faced up. Therefore, when copying the other side, the originals are inverted and conveyed into the exposure region, and are inverted after exposure and returned. In this way, the switch-back route for conveying the originals while maintaining the face-back relation is used only twice, and the original feed speed is increased. Besides, it is not necessary to move the originals only for the purpose of inverting their sides, and the time required for copying operation is shortened.
