Image forming apparatus with selective operation in document-fix reading mode and document-move reading mode

摘要

A copying apparatus has a recirculating document feeder; an exposure device for scanning and exposing the fed document sheets fed onto the document table by the document recirculating device; an image forming device for forming the images on the scanned and exposed document sheets; and a sheet receiving device for receiving and storing the recording medium sheets carrying images formed by the image forming device. The copying apparatus provides a first selecting device for selecting one of a first exposure mode in which the document recirculating device temporarily stations the document sheets on the document table while the exposure device is moved to scan and expose the stationary document sheets and a second exposure mode in which the document recirculating device continuously moves the document sheets on the document table to cause the document sheets to be scanned and exposed; a second selecting device for selecting one of a first receiving mode in which a set of recording medium sheets corresponding to the stack of documents are received and stored in each of a plurality of trays and a second receiving mode in which each of the trays receives and stores a plurality of recording medium sheets corresponding to one of the document sheets; and a control device for controlling the timing of change of the tray into which sheets are ejected in accordance with the modes selected by the first and second selecting devices.
