Abstract
A sheet conveyance device comprises: a skew detector that detects a skewed amount with respect to a conveyance direction of a sheet to be conveyed; and a skew corrector that corrects skew feeding of the sheet, and the skew corrector includes a guide member that supports the sheet along a width direction, and displaces the guide member so as to rotate a region in the width direction of the sheet supported by the guide member about an axis parallel to a conveyance direction according to a skewed amount of the sheet.
Claims3
A sheet conveyance device comprising:
- a skew detector that detects a skewed amount of a sheet to be conveyed with respect to a conveyance direction of the sheet to be conveyed;
- and
- a skew corrector that corrects skew feeding of the sheet, wherein
- the skew corrector includes a guide member that supports the sheet along a width direction, and displaces the guide member so as to rotate a region of the sheet in the width direction of the sheet supported by the guide member about an axis parallel to the conveyance direction according to the skewed amount of the sheet detected by the skew detector,
- the skew corrector
- includes a first support shaft and a second support shaft that are respectively disposed on one side and another side of the sheet with respect to a conveyance path of the sheet in a direction orthogonal to a conveyance direction of the sheet and extend in a width direction of the sheet, and
- integrally rotates the first support shaft and the second support shaft about the axis parallel to the conveyance direction according to the skewed amount of the sheet,
- the guide member includes a first guide member that operates to follow the first support shaft and a second guide member that operates to follow the second support shaft, and
- both side surfaces of the sheet are supported by the first guide member and the second guide member.
