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 1 automatically operates a tray depending on the operating conditions of the automatic document feeder. The automatic document feeder 1 has a set surface 7 on which originals to be conveyed are to be set. An original receiving tray 11 for receiving discharged originals is provided in the vicinity of an original discharge port 10. A lower end of the original receiving tray 11 is rotatable, and a tray driving device is connected to the back of the original receiving tray 11. The tray driving device rotates and displaces the original receiving tray 11 around the lower end depending on the operating conditions of the automatic document feeder 1. The original receiving tray 11 is raised almost perpendicularly until the originals are set on the set surface 7 (see FIGS. 4A and 4D). When the originals are conveyed, the original receiving tray 11 is rotated to an obliquely laid state (see FIGS. 4B and 4C) in order to receive the paper sheets discharged from the discharge port 10. When the originals are set on the set surface 7, the original receiving tray 11 does not interfere with the setting. Further, the original receiving tray 11 is automatically driven, whereby the automatic document feeder 1 is convenient for use.

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 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： In a paper transport device, a first roller serving as a separation roller is situated underneath a second roller serving as a document feed roller, together forming a roller pair. A rotary shaft of the separation roller is biased upward toward the document feed roller by means of an elastic element. One end of the rotary shaft is connected to a drive shaft via a coupler while a connecting bar is joined to the other end of the rotary shaft obliquely from above. An extreme end of the connecting bar opposite to the rotary shaft is attached to a support plate fixed to a main body of the paper transport device in such a way that the connecting bar can swing about pivot pin fixed to the support plate. In the paper transport device thus constructed, one end of the rotary shaft fitted to the coupler acts as a point of support, allowing the other end of the rotary shaft to move downward overwhelming an upward-lifting force of the elastic element when forced downward by the connecting bar. In this construction, the separation roller can be separated from and brought into contact with the document feed roller.

摘要： A sheet transport device is provided with a sheet inverting mechanism for performing a switchback operation in which a sheet transported along a main transport route enters a switchback route, and the sheet transport direction is inverted in the switchback route to return the sheet to the main transport route so as to turn the side of the sheet. A registration roller pair is disposed near the junction between the main transport route and the switchback route. The sheet inverting mechanism is operated in such a manner that the sheet transport is temporarily suspended until a skew correctable portion that enables correction of a skew transport state of the sheet is formed at a lead end of the sheet in the exiting direction from the switchback route after the lead end of the sheet comes into contact with the registration roller pair. Thus, the skew transport state of the sheet which is liable to occur during the switchback operation is corrected.

摘要： It is a major object of the present invention to break down and level a heap-up of toner built in the hopper through dropping from the cartridge when feeding toner into the hopper and to prevent toner from leakage from the cartridge due to erroneous operation with a remarkably simple and cheap construction. Namely, the leveling member moves a plurality of number of times in line with engaging and disengaging operation of the cartridge for the hopper and opening and closing operation of the cartridge in the same direction of the shutter, thereby causing a heap-up of toner built in the hopper housing of the hopper to be effectively broken down and leveled. Furthermore, only when the shutter is in its closed status for the cartridge, the cartridge can be removed from the opening of the hopper.
