    摘要: An automatic document feeder includes first and second registration rollers for abutting the leading end of an original conveyed along a conveying path against their contact positions. The first registration roller is included in a plurality of reversing rollers arranged apart from each other along an axis of a supporting shaft of each of the reversing rollers. The reversing roller turn over the original along a reversing path that bypasses a part of the conveying path. There is provided a reversal guiding member arranged so as to cover a region between the adjacent reversing rollers. The reversal guiding member has guide surfaces curved along the peripheral surfaces of the reversing rollers as viewed along the axis of the supporting shaft. The reversal of the original is guided along the reversing path by the guide surfaces.

    摘要: A document fed from a document tray to a first transport path is guided to a document inverting unit to invert a transport direction of the document. Subsequently, the document is transported to an image reader unit along a second transport path for image data reading on the opposite side of the document opposite to a side facing upward when set on the document tray. Then, the document is guided to the document inverting unit again via a fourth transport path intersecting a third transport path at a first intersecting point to invert the transport direction of the document again. Thereafter, the document is transported to the image reading unit again via the second transport path for image data reading on the one side of the document. The document is discharged onto a discharge tray via the third transport path with the one side facing downward.

    摘要: A recycle document feeder according to the present invention includes a pair of document width regulating guides (9a, 9b) for guiding opposite edges of document originals (D) fed back onto a document placing plate (8) for alignment thereof with respect to the width thereof. With this construction, if the document width regulating guides (9a, 9b) each had a small length (A) as measured along a document transportation direction, the document originals (D) fed back onto the document placing plate (8) could not properly be aligned by the document width regulating guides (9a, 9b) thereby to be randomly stacked on the skew with respect to the document transportation direction. In view of this, the document width regulating guides (9a, 9b) are constructed so as to guide the document originals fed back onto the document placing plate (8) from a document discharge portion (30) over a distance equivalent to or greater than 60% of the length of a smallest document original (as measured along the transportation direction) which is to be possibly transported by the recycle document feeder.

    摘要: In an automatic document feeder, an original tray has an original platen on its upper surface. Originals put on the original platen are fed along a conveying path by conveying rollers and conveyance auxiliary rollers. The originals fed are separated one at a time by separating belts and separating rollers which are arranged above and below a conveying path. When a conveyance guide plate constituting a part of the original platen is removed upward, the separating rollers, the conveying rollers, and the conveyance auxiliary rollers and a portion for supporting the rollers are exposed upward, so that maintenance such as replacement of components such as the separating rollers, the conveying rollers and the conveyance auxiliary rollers can be performed.

    摘要: A sheet transport device is provided with a sheet inverting mechanism for retracting a sheet transported along a main transport route into a switchback route to invert the sheet transport direction and returning the sheet into the main transport route to turn the side of the sheet. The sheet transport device has a pair of sheet guides adapted in contact with respective opposite ends of the sheet set on a sheet setting portion to prevent a skew transport of the sheet. The sheet temporarily brought onto the sheet setting portion during a switchback operation from the switchback route is guided between of the sheet guides on the sheet setting portion. During the temporal appearance on the sheet setting portion, the opposite ends of the sheet are aligned by the respective sheet guides. Thereby, securely prevented is an occurrence of a skew transport state of the sheet during the switchback operation.

    摘要: A recycle document feeder according to the present invention includes a cover (251) covering a document discharge portion (30). The cover (251) is openably supported by a pivot shaft (256) between a pair of frames (255). A feed-back path (32) for guiding a document original onto a document placing plate is defined by a pair of guide members (257, 258) provided in an opposed relation. The upper guide member (258) is attached to the interior face of the cover (251). A switch claw (253) for switching the document traveling direction is attached to the pivot shaft (256) which supports the cover (251). Thus, there is no need for additionally providing a shaft for supporting the switch claw (253), thereby simplifying the construction of the document discharge portion (30).

    摘要: A conveying belt mechanism for an automatic document feeder, for conveying a document placed on a document bearing plate to a document exposure position on a transparent platen. The conveying belt mechanism includes a driving roller and a driven roller disposed above the transparent platen, with a predetermined spacing provided between the two rollers in a document feeding direction, an endless conveying belt looped over the driving roller and the driven roller, pressing rollers disposed between the driving roller and the driven roller for pressing the endless conveying belt against the transparent platen, and belt guides mounted at both ends of the driven roller. Each belt guide includes a boss portion mounted on a rotating shaft of the driven roller so as to be capable of relative rotation, a detachment-preventing portion which protrudes from the boss portion diametrically beyond an outer peripheral surface of the driven roller and which has a front end bent inwardly, and a rotation stopping portion provided in the boss portion, the rotation stopping portion being engaged with a rotation restraining member.
