摘要： PROBLEM TO BE SOLVED: To provide a paper conveying device or the like capable of performing stable conveying of paper in the state that suction force is relatively enhanced at the maximum at a desired area in a rotation shaft direction of a conveying belt when conveying of a constant section is performed while performing adsorption by performing intake suction on an outer peripheral surface of the conveying belt with a ventilation hole for rotating the paper. SOLUTION: An intake duct 3 includes an intake surface part in which a plurality of intake ports opened so as to be opposed to an inner peripheral surface passing through a paper adsorption section of the conveying belt are formed with an interval in the rotation shaft direction of the conveying belt; and a ventilation pipe part connected to an inner surface side of the intake surface part and passing air taken-in from the intake port. In the intake duct 3, the ventilation pipe part is formed in the shape that an intake collection port for collecting/passing the sucked air is arranged at a position included in an area where the intake port for relatively making the suction force highest of the plurality of intake ports is present and a position left from an inner surface side of the intake surface part and an opening cross section area of the ventilation pipe is made relatively narrow as it is left from the intake collection port in the rotation shaft direction of the conveying belt.

摘要： PROBLEM TO BE SOLVED: To provide an image forming device in which the life of a fixing roller is extended without affecting sheet handling. SOLUTION: A pair of register rollers 30 are laterally moved in such a manner that the side end of a sheet lies within a predetermined range in the lateral direction based on the sheet side end information from a side register detection sensor 35 which detects the lateral side end of the sheet S conveyed to an image forming section. When the sheet on which an image is formed is conveyed to a sheet handling section without inverting the sheet, the pair of register rollers 30 are moved in such a manner that the side end of the sheet lies within a first lateral range. When the sheet on which the image is formed is conveyed to the sheet handling section after the sheet is inverted by a sheet re-conveying section, the pair of register rollers 30 are moved in such a manner that, before the inversion, the side end of the sheet comes within a second lateral range which is different from the first lateral range and, after the inversion, the slide end comes within the first lateral range.

摘要： PROBLEM TO BE SOLVED: To provide a paper feed cassette whose operability is improved by aligning a pressing direction for unlocking with an operating direction for a fence member and reducing the pressing force for unlocking. SOLUTION: In this paper feed cassette, when the operating part 33 of a lever 20 fixed to a side fence 9a is pressed in the direction of an arrow 34 (moving direction of the side fence 9a), a stopper 21 installed rotatably around an axis 23 in the direction generally perpendicular to the moving direction of the side fence 9a is rotated to the right side through a tilted part 28. A claw 27 installed at the end of the arm 26 of the stopper 21 comes out of a not-shown groove by displacing upward (in the direction generally perpendicular to the moving direction of the side fence 9a), and the locking is released. The claw 27 is displaced from the vertical wall surface of the groove parallel with each other. COPYRIGHT: (C)2007,JPO&INPIT
