Abstract
According to one embodiment, a sheet conveying device includes a conveying path forming unit and an orthogonal movement permitting part. The conveying path forming unit forms a path for conveying a sheet. The orthogonal movement permitting part is provided in the conveying path. The orthogonal movement permitting part conveys the sheet along the conveying direction. The orthogonal movement permitting part allows the sheet to move in a conveying orthogonal direction orthogonal to the conveying direction.
Claims8
A sheet conveying device, comprising:
- a conveying path forming unit configured to form a conveying path of a sheet;
- and
- an orthogonal movement permitting device provided in the conveying path and configured to convey the sheet along a conveying direction and allowing the sheet to move in a conveying orthogonal direction orthogonal to the conveying direction;
- wherein the orthogonal movement permitting device includes a shaft extending in the conveying orthogonal direction, and wherein the shaft includes only one rubber roller or only one paddle arranged at a center position of the shaft in the conveying orthogonal direction,
- the shaft includes the one rubber roller,
- the one rubber roller has an anisotropic friction generation direction and a contact surface that abuts the sheet, and
- the contact surface has a first friction coefficient in the conveying direction and a second friction coefficient in the conveying orthogonal direction, wherein the second friction coefficient is smaller than the first friction coefficient.
