Abstract: A sheet processing apparatus includes an endless belt configured to convey the sheet by coming in contact with an upper surface of the sheet stacked on the sheet stacking portion, a shaft extending in a direction orthogonal to the sheet conveying direction, and a supporting portion rotatably supporting the drive rotating member and supporting the endless belt through the drive rotating member. The supporting portion is configured to be swingable about the shaft and the endless belt is raised and lowered by the supporting portion being swung by a lifting portion.

Abstract: A sheet feeder comprises a feed deck for supporting a stack of sheets (65) to be fed. The feed deck may be formed by a bed of freely spinning rollers. A feed block (62) comprises a friction pad (66) that projects from the bottom of the feed block (62) towards a drive belt (42) to define a gate therebetween. The drive belt (42) frictionally engages the underside of a bottom sheet of the stack (65) and urges the sheet towards the gate. The feed block (62) comprises a front face (72) immediately upstream from the gate, which is inclined at a sharp angle to the feed direction. The friction pad (66) comprises a lower face that is substantially parallel to the feed direction and does not intersect the plane of the feed block front face (72).

Abstract: A sheet conveying device, that can be included in an image forming apparatus, includes a first conveying unit to convey a sheet in a first sheet conveying direction, a second conveying unit to convey the sheet conveyed by the first conveying unit in a second sheet conveying direction that is different from the first sheet conveying direction, a first sheet conveying path provided between the first conveying unit and the second conveying unit, a belt-type sheet conveying unit to the holding section of the second conveying unit, and a positioning control mechanism to move and position the first supporting member and the second supporting member in respective directions different from each other. The belt-type sheet conveying unit includes a belt, a first rotary belt holding member, a second rotary belt holding member, a first supporting member, and a second supporting member.

Abstract: A tape transport system for printed products includes a tape having a tape width, a pulley, and a lever arm supporting the pulley, the lever arm having a first side and a second side. The pulley has a first section disposed on the first side of the lever arm and a second section disposed on the second side of the lever arm, the first and second sections supporting the tape so that the lever arm is within the tape width.
