Patent ID: 8608164

Claim:
A sheet conveying apparatus, comprising: a sheet conveying unit configured to convey a sheet, including: a driving roller; and a driven roller configured to rotate by being driven by the sheet while conveying the sheet by sandwiching the sheet between the driving roller and the driven roller, wherein a conveying amount measurement unit counts a pulse of a rotary encoder that is provided on a rotation axis of the driving roller or the driven roller; an upstream side guiding member that is provided in an upstream side of a conveying direction of the sheet conveying unit, and that forms an upstream side conveying route of the sheet; a downstream side guiding member that is provided in a downstream side of the conveying direction of the sheet conveying unit, and that forms a downstream side conveying route of the sheet; an upstream side detection unit configured to detect the sheet conveyed in the upstream side conveying route; and a downstream side detection unit configured to detect the sheet conveyed in the downstream side conveying route, wherein a detection position of the sheet for the upstream side detection unit is set between the sheet conveying unit and a position where the sheet is in contact with the upstream side guiding member, in a conveying state where the sheet is conveyed by the sheet conveying unit and the sheet is in contact with the upstream side guiding member and the downstream side guiding member, and wherein a detection position of the sheet for the downstream side detection unit is set between the sheet conveying unit and a position where the sheet is in contact with the downstream side guiding member in the conveying state.
