Abstract
A conveying apparatus includes: a rotation shaft; a conveying roller secured to the rotation shaft; a driven roller that cooperates with the conveying roller to convey a sheet at a nip position; a supporter supporting the rotation shaft rotatably; and a first guide and a second guide opposed to each other and defining a conveyance path guiding the sheet toward the nip position. The first guide and the second guide respectively have first and second guide surfaces defining the conveyance path. The first guide and the second guide respectively have first and second engaging portions engaged with the rotation shaft at positions different from a position of the supporter in the axial direction of the rotation shaft.
Claims15
A conveying apparatus, comprising:
- a rotation shaft configured to be driven to rotate;
- a conveying roller secured to the rotation shaft;
- a driven roller opposed to the conveying roller and configured to cooperate with the conveying roller to nip a sheet at a nip position to convey the sheet;
- a supporter supporting the rotation shaft such that the rotation shaft is rotatable;
- and
- a first guide and a second guide defining a conveyance path that guides the sheet from an upstream side of the nip position in a conveying direction toward the nip position, the first guide and the second guide being opposed to each other in an opposed direction orthogonal to each of the conveying direction and an axial direction of the rotation shaft,
- wherein the first guide comprises:
- a first guide surface defining the conveyance path;
- and a first engaging portion engaged with the rotation shaft at a position different from a position of the supporter in the axial direction of the rotation shaft, and
- wherein the second guide comprises:
- a second guide surface defining the conveyance path;
- and a second engaging portion engaged with the rotation shaft at a position different from the position of the supporter and a position of the first engaging portion in the axial direction of the rotation shaft.
A conveying apparatus, comprising:
- a rotation shaft configured to be driven to rotate;
- a conveying roller secured to the rotation shaft;
- a driven roller opposed to the conveying roller and configured to cooperate with the conveying roller to nip a sheet at a nip position to convey the sheet;
- a bearing supporting the rotation shaft such that the rotation shaft is rotatable;
- a supporter on which the bearing is mounted;
- and
- a first guide and a second guide defining a conveyance path that guides the sheet from an upstream side of the nip position in a conveying direction toward the nip position, the first guide and the second guide being opposed to each other in an opposed direction orthogonal to each of the conveying direction and an axial direction of the rotation shaft,
- wherein the first guide is supported by the supporter and comprises a first recess having a U-shape in cross section and opening upward,
- wherein the second guide is supported by the supporter and comprises a second recess having a U-shape in cross section and opening upward, and
- wherein the rotation shaft is supported by the bearing in a state in which the rotation shaft is inserted in the first recess and the second recess.
