Patent ID: 8480080

Claim:
A sheet processing device comprising: a conveyance member to convey a sheet of recording media with the sheet attached thereon, the conveyance member having a circumferential portion to separate the sheet from the conveyance member by a curvature of the conveyance member; an elastic plate member having a fixed base end and an opposite end opposite the fixed base end, the opposite end contacting the circumferential portion of the conveyance member; a first conveyance path formed by the conveyance member to convey the sheet; and a second conveyance path disposed downstream from the first conveyance path in a sheet conveyance direction of the first conveyance path and including a reversal conveyance path to reverse the sheet sent from the conveyance member, wherein the sheet conveyed along the first conveyance path is separated from the conveyance member by the curvature and introduced to the second conveyance path, the sheet reversed along the second conveyance path is conveyed to the circumferential portion of the conveyance member from a direction of a first angle different from a second angle at which the sheet is introduced from the first conveyance path to the second conveyance path, and attached on the conveyance member, and a face continuous to a front edge of the elastic plate member, except for the front edge, is positioned in an attachment weakened area of the circumferential portion of the conveyance member in which an attachment force of the sheet on the circumferential portion of the conveyance member is weakened by separation of the sheet from the conveyance member by the curvature of the conveyance member.
