Claims

[Claims for Utility Model Registration] 1. A take-up spool that is rotationally driven by a driving means and winds up the ribbon; a supply spool that supplies the ribbon; a resistor that applies rotational resistance to the supply spool; A resistance applying means is provided in the supply path and applies a smaller resistance to the ribbon when it passes as the outer diameter of the stacked ribbons wound around the supply spool becomes smaller. Features a ribbon cassette. 2. Utility model registration claim 1, characterized in that the resistance imparting means comprises two guide members that are protruded at intervals in the ribbon supply path and guide the ribbon.
Ribbon cassette as described in section.
