Abstract
A printing cassette to be attached to and detached from a printing apparatus main body is provided. The printing apparatus main body includes a drive shaft rotatable around an axis. The printing cassette includes: a first tape; a spool around which the first tape is wound or is to be wound and rotatable around a rotational axis parallel to a first direction; a first engaging portion of the spool configured to transmit a driving force of a drive shaft to the spool; and an input gear disposed at a different position from the spool in the first direction and engageable with another gear. The first engaging portion and the input gear engage with the drive shaft at different positions in the first direction when the printing cassette is attached to the printing apparatus main body.
Claims18
A printing cassette, comprising:
- a case;
- a supply spool located in the case;
- an ink ribbon wound around the supply spool;
- an input spool rotatable about a rotation axis extending in a first direction, the input spool is configured to take up the ink ribbon from the supply spool, the input spool having a first hollow defined by an inner peripheral surface of the input spool, the input spool including first spline teeth located at the inner peripheral surface of the input spool;
- and
- an input gear rotatable about the rotation axis, the input gear including gear teeth, the input gear having a second hollow defined by an inner peripheral surface of the input gear, the input gear including second spline teeth located at the inner peripheral surface of the input gear,
- wherein the second spline teeth are in the first hollow, and
- wherein the input gear is located in the case.
