An image scanning machine includes a document feeder for feeding sheets into a first paper path from a stack one sheet at a time if a one-side scanning mode is selected. If a both-side scanning mode is selected, a sheet is introduced into a second paper path which is an inverting path that turns a sheet, which is fed from the document feeder, upside down prior to scanning. Rollers located at a downstream end of the inverting path reverse a transportation direction of the sheet and feed the sheet to a scanner through a return path. The transportation direction of the sheet is reversed after the scanner scans one side of the sheet, and the sheet is then fed to the scanner again to scan the other side of the sheet. This transportation direction reversal results in turning the sheet upside down. A guide member is located a bifurcation of the return path and the inverting path for opening one of the return and inverting paths and closing the other of the return and inverting paths. Another guide member is located a bifurcation of the first and second paper paths.

A both-face automatic original feeding apparatus wherein a plurality of originals having images on their first and second surfaces are successively supplied from an original stacking portion to a predetermined position for reading an original, and each original is reversely rotated through a switch-back path after the first surface of the original passes through the predetermined position, thereby supplying the original to the predetermined position again to direct the second surface of the original to the predetermined position. In such a feeding apparatus, there is provided an introduction path for directing the original supplied from the original stacking portion to the predetermined position; a first discharge path for directing the original to the switch-back path after the original passes through the predetermined position; a surface reverse path for directing the original from the switch-back path to the predetermined position after reversing a first surface and a rear surface of the original; and a controller for controlling the apparatus in such a manner that a preceding original is switched back to convey it in the surface reverse path while a succeeding original is being passed through the predetermined position, and, when a trailing end of the succeeding original leaves the predetermined position, a tip end of the preceding original reaches the predetermined position.

A copying system which has a copying machine for forming an image on a sheet, a circular transporting device for receiving a sheet which has obtained an image on one side from the copying machine and refeeding the sheet to the copying machine for image formation on the other side of the sheet, and an automatic document feeder with a document reversing mechanism. The automatic document feeder sets a document at a specified position on a document table and discharges the document from the document table. Further, in handling a double-side document which has images on both sides, the automatic document feeder turns over the document after scanning of an image of one side. When a number of copies over the capacity of the circular transporting device are to be made in a double-side document/duplex copy mode, the document is turned over every time a number of copies corresponding to the capacity of the circular transporting device has been made.

Documents stacked in a document tray are fed from the lowermost sheet by a feeding belt and then by a feeding belt to a light exposure station via feeding rollers, and after light exposure are recirculated onto the uppermost sheet of the document tray by a inverted feeding roller via an ejection roller. When the documents are double-sided, they are invertedly fed in the direction of a feeding path by the feeding roller, fed to the light exposure station, and each side of the documents presented for light exposure. Here, when trouble occurs in the copying unit, the document in the feeding path is returned to the document tray while recirculative feeding of the documents remaining in the document tray is performed for automatic restoration of the documents to their originally stacked state when returned to the tray. Therefore, only the minimum necessary number of documents are fed through the inverted feeding path. Thus, restoration of the initial stacked state of the documents may be carried out automatically for shortening of the time required therefor.

A plurality of double-faced originals in a series of pages are stacked on a tray with a first page faced upward. An original transport mechanism is arranged to transport a first sheet of original fed by a feed roller to an exposure position through an intermediate waiting position on a platen glass for image exposure of a first page. Then, the original transport mechanism forwards the first sheet of original to a reverse/discharge roller provided downstream side of a transport belt to invert the surface and reverse side of the original. Thereafter, the original is returned to the intermediate waiting position by the transport belt.Further, the original transport mechanism forwards a second sheet of original preliminarily fed to a position just before the transport belt to the exposure position by the transport belt side by side with the first sheet of original for an image exposure process without having a gap between second page of first original and third page of the second original to simultaneously expose images on one copy sheet. Thereafter, the original transport mechanism repeats the same procedures for a preceding original and a succeeding original to be fed preliminarily.

An image forming apparatus has a plurality of mixed input thereto including one-sided and two-sided documents, and then copied on sheets which are successively outputted in accordance with the supplied documents. The apparatus has a feeder to feed the documents to a reading station, and a discriminator to discriminate whether each of the documents is a one-sided or a two-sided document. Then the apparatus selectively outputs copied sheets in either a one-sided copy mode, a two-sided copy mode or a mixed copy mode in which one-sided and two-sided copy sheets are outputted in accordance with the mixed one-sided and two-sided documents.
