Claims

[Claims for Utility Model Registration] A carriage that supports a printing mechanism and moves in the printing direction, a printing ribbon cassette mounted on the carriage and containing a printing ribbon, the printing ribbon and erasing printing by the printing ribbon. An erasing ribbon cassette for use in a printing device, comprising a ribbon selection mechanism for selectively positioning an erasing ribbon to a working position opposite to a print line, and an erasing ribbon feeding mechanism for feeding the erasing ribbon, the erasing ribbon cassette comprising: A supply spool formed at a position corresponding to one side of the carriage with respect to a plane perpendicular to the direction of movement, and holding a supply spool wound with an erasing ribbon in a rotatable state about an axis parallel to the direction of movement of the carriage. A supply spool holder and a take-up spool formed at a position corresponding to the other side of the carriage and connected to the erasing ribbon feeding mechanism for winding the used erasing ribbon are arranged along an axis parallel to the moving direction of the carriage. a take-up spool holding part that is rotatably held around the main body; a plate-shaped connecting part that connects the supply spool holding part and the take-up spool holding part beyond the printing ribbon cassette on the carriage; and the printing part. An erasing ribbon cassette for a printing device, comprising: an engaging portion that removably engages with the ribbon cassette.
