Abstract
A transporting roller is formed of a metal plate formed into a cylindrical shape so that a pair of end surfaces oppose each other and having a joint line extending in the axial direction formed by the pair of the end surfaces including: a high friction layer formed on a surface of the roller and configured to come into contact with a transported medium; an opening provided out of the high friction layer; and a gear member disposed so that an inner peripheral surface is located on the opening.
Claims4
A printing apparatus comprising:
- a transporting roller that includes a cylindrical shaft formed from a material and having a joint formed by two opposing end surfaces of the material bent and brought into abutment with each other, the joint extending between axial ends of the cylindrical shaft;
- a driven roller that, together with the transporting roller, nips a recording medium and transports the recording medium;
- a recording unit that records on the recording medium;
- a high friction layer formed on a surface of the transporting roller and configured to come into contact with the recording medium during its transport;
- wherein the joint further comprises:
- a first joint section extending along the axial direction of the cylindrical shaft, and
- a projection provided at one axial end of the cylindrical shaft, the projection projecting in a direction cross-wise to the direction of the first joint section,
- wherein a first spacing between opposing end surfaces in the projection is greater than a second spacing between opposing end surfaces in the first joint section;
- wherein the printing apparatus further comprises:
- a gear member disposed so that an inner peripheral surface of the gear member is located on the first spacing.
