Patent ID: 8181957

Claim:
A sheet conveying apparatus comprising: first and second rollers that are arranged in positions different from each other in a direction orthogonal to a sheet conveying direction and can be driven to rotate independently from each other; a first skew detecting unit that is arranged on a downstream side of the first and second rollers in the sheet conveying direction and detects a skew of a sheet with a first skew detection accuracy, the first skew detecting unit comprising sensors which are arranged in positions different from each other in the direction orthogonal to the sheet conveying direction; a second skew detecting unit that is arranged further on the downstream side than the first skew detecting unit in the sheet conveying direction and detects a skew of the sheet with a second skew detection accuracy which is higher than the first skew detection accuracy, the second skew detecting unit comprising sensors which are arranged in positions different from each other in the direction orthogonal to the sheet conveying direction and comprising more sensors than the first skew detecting unit; a skew determining unit that determines a skew amount of the sheet on the basis of detection results of the respective first and second skew detecting units; and a driving control unit that controls to drive, to reduce the skew amount determined by the skew determining unit, the first and second rollers independently from each other and convey the sheet.
