摘要： An automatic document feeder, which is included in an image reading device and an image forming apparatus, includes first and second document trays, a document output tray, a document conveying passage, multiple document conveying bodies, a drive source, a detector, and a controller. The multiple document conveying bodies include a document holding and conveying body to convey and hold the original document sheet on the second document tray. On detection of the original document sheet on the second document tray while conveying a different original document sheet from the first document tray, the controller stops feeding the different original document sheet, causes the different original document sheet downstream from the document holding and conveying body in a document conveying direction to be conveyed to the document output tray, and stops the drive source after the different original document has been conveyed to the document output tray.

摘要： A document feeder, which may be incorporated in an image forming apparatus, includes a sheet conveying guide, at least one recess, a frame, and at least one protrusion. The sheet conveying guide is disposed facing an exposure glass on an apparatus body and guides an original document passing over the exposure glass when the document feeder is closed to the apparatus body. The recess is disposed on the apparatus body at both ends of the exposure glass in a lateral direction orthogonal to a document conveying direction. The frame is openably closable about one end side of the apparatus body in the lateral direction and vertically movably holds the sheet conveying guide. The protrusion is disposed on the frame facing the recess. The sheet conveying guide and the frame are secured to each other while the recess and the protrusion are engaged with each other in the closed state.

摘要： An automatic document feeding device includes a document tray, an ejection tray, and a document takeout port. The document tray is rotatably attached to a rotation fulcrum provided in a body of the automatic document feeder, to load a document. The document tray includes a first positioner and a second positioner. The first positioner is disposed at a front side of the body in a direction perpendicular to a document feed direction. The second positioner is disposed at a depth side of the body in the direction perpendicular to the document feed direction. The first positioner is disposed upstream from the rotation fulcrum in the document feed direction and above the document takeout port in the body. An upper portion and side surfaces of the first positioner in the direction perpendicular to the document feed direction are surrounded by the document tray in a closed state of the document tray.

摘要： An automatic document feeding device includes a conveyance unit, an image reading unit, a color reference member, a moving assembly, and a drive source. The drive source includes a rotation output shaft to drive the conveyance unit and the moving assembly. The drive source changes the rotation output shaft from a forward rotation direction to a reverse rotation direction to reversely rotate the rotation output shaft to a set reverse rotation angle set in advance, according to a condition of conveyance of the document. In a rotation transmission route from the rotation output shaft to the moving assembly, the movement regulator is disposed in a first reverse rotation drive region from when a rotation direction of the rotation output shaft is changed to the reverse rotation direction to when a rotation angle of the rotation output shaft after the change in the reverse rotation direction reaches the set reverse rotation angle.

摘要： An image reading device includes an image reader movable along an image reading face, a casing to house the image reader, including a restraint holder, and a restraint to be held by the restraint holder of the casing and configured to restrict movement of the image reader. The restraint includes an operation portion to be disposed outside the casing. The operation portion is operated to move the restraint, in the restraint holder, to: a restricting position to restrict movement of the image reader; a first unlock position to cancel restriction of movement of the image reader; and a second unlock position at which movement of the image reader is not restricted. At the first unlock position, movement of the restraint to the restricting position is allowed. From the second unlock position, movement to the restricting position is less smooth than movement from the first unlock position to the restricting position.

摘要： A sheet conveyance device includes a sheet mount on which a standard-sized sheet is mountable; a first conveyor to bring in the sheet from the mount, convey the sheet through a reverse conveyance path such that the sheet passes through a specific operation position, and eject the sheet into a sheet ejection area outside the mount; and a second conveyor to bring in a hard sheet with a higher bending rigidity than the sheet from one end of a straight conveyance path along a plane passing through the specific position of the reverse path, and eject the hard sheet conveyed along the straight path from another end of the straight path at a sheet ejection area side. The mount includes a hard sheet ejection port to let through at least a leading edge portion of the hard sheet to be ejected from the second conveyor in a sheet ejection direction.

摘要： There is provided a method of fabricating a three-dimensional object. The method includes supplying, flattening, and collecting. The supplying supplies, with a powder supplier, powder to a fabrication chamber. The fabrication chamber includes a fabrication stage to store powder and an outer edge portion outside the fabrication stage, the outer edge portion having one bottom surface. The flattening flattens, with a flattener, the powder supplied by the supplying. The collecting collects, with a powder collector, the powder having overflowed from the fabrication stage to the outer edge portion by the flattening into the fabrication stage.
