Abstract
A conveying apparatus includes a sheet conveyance path including a curved portion, and a roller pair that is located along the conveyance path and conveys a sheet. At least one of rollers of the roller pair moves such that the orientation of conveying force exerted onto the sheet by the roller pair at its nip point is changed after the roller pair pinches the sheet.
Claims11
A conveying apparatus, comprising:
- a sheet conveyance path including a curved portion having an inner guide and a outer guide;
- a roller pair including a first roller located on the inner guide and a second roller located on the outer guide and configured to pinch a sheet;
- and
- a mechanism configured to move the first roller to an upstream side with respect to a sheet conveying direction by a first amount and move the second roller to the upstream side with respect to the sheet conveying direction by a second amount which is smaller than the first amount after the roller pair pinches the sheet,
- wherein the first roller is a drive roller that is supported by a swing member and rotates by a drive force transmitted from a drive source, and when conveyance resistance of the sheet increases, the drive force swings and swing member.

A recording apparatus comprising:
- a recording head configured to record images on a sheet;
- a conveying roller located upstream of the recording head in a sheet conveying direction and configured to convey the sheet;
- a feeding roller located upstream of the conveying roller in the sheet conveying direction and configured to feed the sheet;
- a sheet conveyance path located between the feeding roller and the conveying roller and including a curved portion having an inner guide and an outer guide;
- a first roller located on the inner guide, the first roller being a drive roller that rotates by a drive force transmitted from a drive source;
- a first swing member configured to support the first roller, wherein the drive force from the drive source swings the first swing member when conveyance resistance of the sheet increases;
- a second roller located on the outer guide;
- and
- a moving unit configured to move the first roller to an upstream side with respect to the sheet conveying direction by a first amount and move the second roller to the upstream side with respect to the sheet conveying direction by a second amount which is smaller than the first amount.
