摘要： An image scanner includes a stationary original plate on which a stationary original is placed and a moving original plate, over which a moving original is conveyed, aligned with the stationary original plate in a sub-scanning direction and tilted relative to the stationary original plate by a given angle. A reader is movable in the sub-scanning direction between a stationary original reading span disposed opposite the stationary original via the stationary original plate to read an image on the stationary original and a moving original reading position disposed opposite the moving original via the moving original plate to read an image on the moving original. The reader pressingly contacts the stationary original plate and the moving original plate as the reader moves in the sub-scanning direction.

摘要： A sheet conveyance unit including a sheet tray on which a stack of sheets is placed, a sheet feed member to feed sheets from the stack of sheets, a separation/feed unit to separate a topmost sheet from the rest of sheets fed by the sheet feed member and feed the topmost sheet to a predetermined position, and a pre-separation unit disposed between the sheet tray and the separation/feed unit. The pre-separation unit includes a downward sloped portion to guide a leading edge of each sheet diagonally downward, and an upward sloped portion provided downstream from the downward sloped portion in a conveyance direction of the sheets to guide the leading edge of each sheet diagonally upward. Both ends of the upward sloped portion in a lateral direction are sloped upward more gently than the center of the upward sloped portion.

摘要： An image forming apparatuses includes an apparatus body configured to house a replacement part. The apparatus body includes a guiding face configured to guide a guided face of the replacement part. The guided face is on a side along a movement direction in which the replacement part moves between a set position in the apparatus body and an attaching and detaching position at which the replacement part is attached to and detached from the apparatus body. The apparatus further include a moving device configured to move the replacement part between the set position and the attaching and detaching position, and a pressing device configured to press the guided face of the replacement part against the guiding face of the apparatus body while the replacement part moves between the set position and the attaching and detaching position.
