A medium ejection device includes a housing, an ejection roller, an opposing roller, and a tray. The housing includes: a medium conveyance path tilted to be lower toward a downstream end of the path in a medium ejecting direction to eject a medium downward; and a wall portion disposed below a nip surface between the ejection roller and the opposing roller. The wall portion is not overlapped, when viewed from a direction perpendicular to the medium ejecting direction, with a circle that is centered at an intersection point between an extension line of the nip surface and a placement surface of the tray and passes through a point closest to the intersection point on outer circumference surfaces of the ejection roller and the opposing roller such that, when the ejected medium falls down, a rear end of the medium does not come into contact with the wall portion.

A sheet feed roller (1) is provided, which is formed of an elastomer composition containing a thermoplastic elastomer, a spherical filler and a low friction silicone compound, and has a friction coefficient of not greater than 0.5. A production method is also provided, which includes the step of extruding the elastomer composition through a die configured as corresponding to a sectional shape of the sheet feed roller.

A medium discharging device includes a paper discharging tray that is disposed below a height position of a discharging roller which discharges a medium and includes a placing surface on which the medium discharged by the discharging roller is placed, and a supporting member that is configured to be movable between a retreat position on an upstream side and an advance position on a downstream side between the discharging roller and the placing surface.

Disclosed is a post-processing apparatus couplable to an image forming apparatus. The post-processing apparatus comprises: a paper discharging roller to convey, from a conveying path, a first paper discharged from the image forming apparatus, to a standby path connected to the conveying path, and convey the first paper from the standby path and a second paper discharged from the image forming apparatus from the conveying path, to an intermediate loading part, in a state in which a leading end of the first paper toward the intermediate loading part protrudes more than a leading end of the second paper toward the intermediate loading part to process the first paper and the second paper.

Methods and apparatus for transporting either an entire web or discrete components of disposable products such as diaper components down the machine using mechanical forces to grip the nonwoven web and transfer it from one belt or roll to another without or reducing added vacuum. There is a carrier nonwoven web that goes down the length of the machine and other substrates are added on top of this layer, and the machine provides sufficient gripping to allow transport of diaper components through the fabrication process. Securing and releasing forces are supplied so that the components can be retained at some points and released at others.

A paper feed roller of the present invention comprises a roller body 2 integrally formed of elastic material in a cylindrical shape in which a plurality of protruding lines 6 are disposed on a peripheral surface 5 at even intervals, wherein the roller body 2 is formed so that crest portions 6a and trough portions 6b are continuously provided in a circumferential direction, an opening angle is equal to or more than 2 and is equal to or less than 8, a radial height h of the protruding line is equal to or more than 0.051 mm and is equal to or less than 0.1 mm, and a curvature radius r1 at a shoulder is equal to or more than 0.55 mm.

A medium winding device for winding a medium includes: a rotatable winding member; a driver configured to rotate the winding member to wind the medium around the winding member into a roll; a rotating friction member rotatably disposed upstream of the winding member in a conveying direction in which the medium is conveyed, the rotating friction member having a high friction member forming an outer surface of the rotating friction member, and being configured to apply tension to the medium when the medium is wound around the winding member; and a tension adjusting member connected to the rotating friction member and configured to maintain the tension applied to the medium constant.

A conveying apparatus includes: a casing formed with a first sheet-conveyance passage and a second sheet-conveyance passage positioned inwardly as compared with the first sheet-conveyance passage; a cover member including a first resin member having a first guide surface for defining the first sheet-conveyance passage, a second resin member attached to the first resin member and located on an inner side of the casing than the first guide surface and defining the first sheet-conveyance passage, and a third resin member attached to the second resin member at a position opposite to the first resin member with respect to the second resin member and having a third guide surface for defining the second sheet-conveyance passage; and a metal frame attached to the second resin member at a position between the second resin member and the third resin member.

A post-processing apparatus for post-processing paper discharged from an image forming apparatus comprises: a paper discharging roller for conveying both first and second paper sequentially discharged from an image forming apparatus to an intermediate loading part; a main paddle part for conveying the first and second paper loaded on the intermediate loading part to a compiling region; a reverse roller for conveying, together with the main paddle part, the first and second paper to the compiling region; and a binding part for processing the first and second paper conveyed to the compiling region, the paper discharging roller allows the first paper to stand by on a standby path, and conveys the first and second paper to the intermediate loading part in a state in which the leading end of the first paper protrudes further than the leading end of the second paper.
