Abstract
A sheet conveying apparatus includes a sheet conveying unit that conveys a sheet including a drive roller, a driven roller, and a rotary encoder provided on a rotational axle of one of the drive roller and the driven roller; a conveying amount measuring unit that measures a conveying amount of the sheet; a first detection unit positioned downstream of the sheet conveying unit, the first detection unit being positioned apart from the drive roller and the driven roller not to overlap with the drive roller and the driven roller in the conveying direction; a second detection unit positioned upstream of the sheet conveying unit; and a conveying distance calculation unit that calculates a conveying distance of the sheet based on the measured result by the conveying amount measuring unit and the detected results detected by the first detection unit and the second detection unit.
