An image reading apparatus includes a platen, a frame for holding the platen, an installation device disposed to the frame so that the platen can be held in a substantially vertical state, and a scanning device for reading a document along the platen substantially vertically held. The reading of the document is carried out by elevating or lowering the scanning device.

A document feeder is formed of a reading section for reading an original document while the original document is being transferred; a transfer roller having a transfer path therearound with an inlet located near the reading section and an exit so that the original document is transferred from the inlet to the exit through the reading section; and first and second rollers pressed against the transfer roller. The first and second rollers are located respectively in upstream and down stream sides of the transfer path relative to the reading section. A guide member is overlapped with the transfer roller at one end so that the original document from the second roller is guided from the one end to the other end.

Compact automatic document feeder with compact document reversing device

A document feeder of the invention is formed of a platen for reading and scanning original documents, a document tray for placing the original documents to be processed situated above the platen, and an ejection tray for receiving the original documents after being processed situated between the platen and the document tray spaced apart from each other in a vertical direction. A transfer path is formed for transferring the original documents from the document tray to the ejection tray through a reading position on the platen. An exit of the document tray, an entrance of the ejection tray and the reading position on the platen are arranged laterally in this order above the platen with a predetermined distance spaced apart from each other. A separating portion for separating the original documents one by one is situated between the exit of the document tray and the entrance of the ejection tray to be laterally spaced apart from each other. The document feeder is made compact in size.

A document feeder is formed of a reading section for scanning an original document while the original document is being transferred at a predetermined speed; a feeding stacker for supplying the original document to the reading section; a transfer roller having a transfer path therearound for guiding the original document transferred from the feeding stacker to the reading section; and first and second rollers located respectively in upstream and down stream sides of the transfer path for transferring the original document. A sensing device is located in the transfer path between the first and second rollers for detecting a front edge of the original document. A driving device is connected to the transfer roller to control a rotational speed of the transfer roller based on a detecting signal of the sensing device.

There is provided a transfer path for receiving a document fed, sheet by sheet, from a document placing device, and for leading the document toward a document reading portion for reading the document placed on a stationary platen of an image forming device. In a space between the document reading portion and the document placing device disposed above the document reading portion, there is provided a switchback path for leading the document ejected from the transfer path toward an inlet side of the transfer path by a switchback-transfer. Therefore, a structure of the image forming device can be compact, front and back surfaces of the document can be automatically reversed, and an image on the document can be read while the document is being transferred.

An electrophotographic apparatus of this invention includes a stacking section for cut sheet; a stacking section for fanfold paper; a feed section for supplying printing paper which is cut sheet or fanfold paper from one of the stacking sections via one of different supplying paths; an exposure unit for forming an electrostatic latent image on a photosensitive drum; a developing unit for developing the latent image into a toner image; a belt conveyer for conveying the printing paper received from the feed section along common feeding path, a transferring unit for transferring the toner image on the photosensitive drum onto the printing paper; a fixing unit for fixing the transferred toner image on the printing paper; an ejecting section for receiving the printed printing paper from the belt conveyer; and a cutting device for cutting apart the printed fanfold paper at the perforation line thereof. The fanfold paper left behind on the common feeding path after the cutting operation is set back to a position which does not obstruct supply of cut paper in the feed section.
