Abstract
An ink ribbon cassette includes an elastic engaging portion configured to engage with a rotation regulating portion of a supply bobbin or a rotation regulating portion of a winding bobbin to regulate rotation of the supply bobbin or the winding bobbin. The elastic engaging portion is elastically deformable in a direction of rotation axes of the supply bobbin and the winding bobbin.
Claims30
An ink ribbon cassette comprising:
- a supply bobbin around which an ink ribbon is wound;
- a winding bobbin configured to wind the ink ribbon supplied by the supply bobbin;
- a housing configured to support the supply bobbin and the winding bobbin in such a manner that the supply bobbin and the winding are substantially parallel to each other and are rotatable;
- and
- an engaging member configured to engage with a rotation regulating portion of the supply bobbin or a rotation regulating portion of the winding bobbin to regulate rotation of the supply bobbin or the winding bobbin, and to be elastically deformable in a direction of rotation axes of the supply bobbin and the winding bobbin.

A printer to which an ink ribbon cassette is attachable, the printer comprising:
- an ink ribbon cassette including a supply bobbin around which an ink ribbon is wound, a winding bobbin configured to wind the ink ribbon supplied by the supply bobbin, a housing configured to support the supply bobbin and the winding bobbin so that the supply bobbin and the winding are substantially parallel to each other and are rotatable, and an engaging member elastically deformable in a direction of rotation axes of the supply bobbin and the winding bobbin and configured to engage with a rotation regulating portion of the supply bobbin or a rotation regulating portion of the winding bobbin to regulate rotation of the supply bobbin or the winding bobbin;
- an insertion opening to allow the ink ribbon cassette to be attached or removed in the direction of the rotation axis of the supply bobbin;
- and
- a contact portion configured to come into contact with the engaging member when the ink ribbon cassette is attached to the printer so that the engaging member is elastically deformed to disengage from the supply bobbin or the winding bobbin, to release regulation of the rotation of the supply bobbin or the winding bobbin,
- wherein the engaging member projects from a surface of the housing that is substantially parallel to the rotation axis of the supply bobbin, and
- wherein a side wall portion, which is a surface of the housing that is substantially orthogonal to the supply bobbin, projects beyond the engaging member.
