摘要： A document feeder which picks up documents from a tray, separates/feeds a document with a feed roller and a separation roller and transports the document on a reading position with read rollers. The speed of feeding a document by the feed roller is higher than the speed of transporting a document by the read rollers. The reading position is at a distance from the nip portion between the feed roller and the separation roller, the distance being longer than the length in the document feeding direction of the document.

摘要： A document feeder which has a feed roller for feeding a document picked up from a tray toward a reading position, a first pair of rollers which is located immediately before the reading position, a second pair of rollers which is located immediately after the reading position, and a document sensor. After the leading edge of the document transported by the feed roller comes to the first pair of rollers, the feed roller keeps rotating for a specified time, whereby, registration of the document is carried out. In response to a signal which is generated when the document sensor detects the trailing edge of the document, feeding of a next document is started.

摘要： According to a document transport device of a preferred embodiment, when reading images of a plurality of one-sided documents, these one-sided documents are accommodated in a first accommodating portion with the document surface facing upward. The held documents are fed sequentially from the uppermost document to the first document transport path, inverted front-to-back, and transported with the document surface facing downward to the predetermined position, i.e., the document reading position. When the reading of the document is completed at the document reading position, the read document is transported to a second document transport path, inverted front-to-back, and accommodated in a second accommodating portion with the document surface facing upward. Thereafter, the document is transported to a third document transport path, inverted front-to-back, and accommodated in a third document accommodating portion with the document surface facing downward. The second and subsequent documents are similarly transported, and stacked in the third accommodating portion with the document surfaces facing downward.

摘要： A toner cartridge and a process cartridge, individually, have a shutter which makes sliding movement by opening and closing their toner inlet and toner outlet. When those cartridges are attached to a color printer and fixed together by a fixing lever, the shutters of both cartridges and the fixing lever can move together as one. When they make sliding movement together, both of the shutters are opened and toner supply becomes available. There are thus realized a toner cartridge, a process cartridge, an imaging cartridge, and an image forming apparatus to which those cartridges are attachable, all of which can prevent toner leakage from both a toner housing portion and a process portion and enables even an unaccustomed user to attach each cartridge without making surroundings dirty.

摘要： An image forming apparatus is provided with an automatic document feeder 20 having an original tray 2101, image reading sections 11 and 12 and a printer section P. The apparatus is provided with an insertion sheet detector for discriminating, when a composite original sheet group obtained by inserting between arbitrary pages of a first original sheet group comprised of original sheets of an identical size an insertion sheet of a size identical to that of the original sheets is set on the original tray 2101, whether the sheet fed to the image reading position is the original sheet of the first original sheet group or the insertion sheet. Through the process of forming the print group corresponding to the above composite original sheet group, the image of a second original prepared separately from the composite original sheet group is formed instead of the image of the insertion sheet. This image forming apparatus can automatically reliably form in a short time a print group corresponding to a state in which a certain original sheet group receives another original sheet to be inserted between arbitrary pages of the original sheet group.

摘要： An automatic document feeder (ADF) for feeding a document across a platen is attachable to different types of copying machines which have different copying speeds. The ADF has a detector for detecting the copying speed of the copy machine and a controller for adjusting the document feeding speed of the ADF to the copying speed of the copy machine. The controller also controls the feeding speed of the document at a standard speed in a condition which does not lower copying efficiency and at a higher speed in a condition which lowers copying efficiency. A condition which does not lower copying efficiency is feeding documents other than the last document from the platen. A condition which lowers copying efficiency is feeding the first document to the platen and ejection of the last document from the platen.

摘要： A sheet refeeding apparatus which comprises a belt laid between a first and a second shafts, wherein as the belt is wound around the first shaft, copy sheets ejected from a copying machine are wound around the first shaft together with the belt, and as the belt is wound around the second shaft, the sheets wound around the first shaft are fed out thereof back to the copying machine. In collecting sheets, the first shaft is rotated in the same direction as that of the rotation of a photosensitive drum, and a sheet turn-over section is disposed upstream of the belt with respect to sheet conveying direction. Marks are provided for the belt to recognize the position of the belt. An initial position mark is given to the belt, and the mark functions as a standard for a return of the belt to the initial position on a supply of power for the apparatus or on the completion of a sheet refeeding operation. Further, when a sheet is detected being fed out of the belt during the return of the belt to the initial position, it is judged that a paper jam has occurred, and the returning operation is discontinued. The sheet refeeding apparatus comprises an ejection path through which sheets are ejected directly outside of the apparatus, an ejection path cover which is capable of opening and closed, and a switch for requesting coercive ejection of sheets. The switch is operative from the outside only when the cover is in an open state, and when the switch is operated, sheets are ejected onto the cover. Furthermore, the drive of the belt is controlled, when collecting sheets, to reduce the intervals among the sheets, when feeding the sheets out of the collecting section back to the copying machine, to gain the intervals among the sheets and when ejecting the sheets outside of the apparatus, to keep the intervals among the sheets as they were collected. The coercive ejection is allowed only when a sheet which is unnecessary for the sheet refeeding is included.
