    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.

    摘要： This invention relates to a document transport device for use in an image forming apparatus. The document transport device has a first belt roller disposed above a document positioning member. A second belt roller is disposed away from the first belt roller in the document transport direction. An endless belt is wound around the first and second belt rollers. Plural presser rollers are arranged on a specified position between the first and second belt rollers to press the belt against a contact glass. The document transport device has a tension roller between the first belt roller and the presser roller closest thereto to apply a tension force to the belt so as to set the belt at the lowermost position of the tension roller below a common tangential line to the circumferences of the first belt roller and the presser roller and apart from the contact glass.

    摘要： A recycle document feeder includes a partitioning unit (17) and action plates (19, 20). The partitioning unit (17) includes a partitioning bar (18). When the partitioning bar (18) is lowered, the leading edges of discharged document originals are stopped by the partitioning bar (18). The action plates (19, 20) guide the discharged document originals toward an upper side of the trailing edges of document originals yet to be fed, and push the trailing edges of the discharged document originals to transport the document originals for re-feeding thereof. The partitioning unit (17) and the action plates (19, 20) are driven by a common motor (47). Further, a partitioning unit driving mechanism (110) and an action plate driving mechanism (111) are provided for driving the partitioning unit (17) and the action plates (19, 20), respectively.

    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 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： An opening for discharging toner is formed in a lower part of a cartridge body containing toner. A shutter mounting body is mounted on the opening. A first shutter is slidably mounted on the shutter mounting body. A second shutter is slidably mounted on the first shutter. A front end of a sealing member for sealing the opening is extended, the extended front end being inserted through a seal traction opening formed in a front end of the second shutter, and fixed to a front end of the first shutter. When the second shutter is pulled out of the shutter mounting body, the sealing member is towed by the seal traction opening. In addition, the first shutter is further towed by the sealing member, to be also pulled out. Consequently, nearly half of the sealing member from its front end is stripped. When the second shutter is further pulled out after the movement of the first shutter is regulated, the seal traction opening in the second shutter tows the sealing member while allowing the insertion of the sealing member. At this time, the sealing member is stripped while being so folded that a toner adhering surface is located in its inside. In this construction, the stroke for stripping is decreased, thereby to make it possible to prevent contamination by toner as well as prevent a large part of the sealing member from being ineffective.
