A ribbon cassette includes: a cassette case having first and second holes; an ink ribbon; first and second spools; an engaging part; and a spring member. The ink ribbon has one end wound on the first spool, and another end connected to a first end portion of the second spool. The spring member is wound around a second portion of the second spool. The spring member includes: a winding part wound around the second portion; and an extension part extending from the winding part and engaged with the engaging part. The winding part is wound in a direction opposite to a take-up direction of the second spool. A second draw-out load applied to the ink ribbon being pulled from the second spool through the second hole is smaller than a first draw-out load applied to the ink ribbon being pulled from the first spool through the first hole.

A tape support arrangement comprises a tape take up core (220) suitable for supporting a tape; and a tape supply core (210) suitable for supporting a tape (230). The supply core (210) comprises an inner surface (212), the inner surface defining an internal volume (240) of the supply core and being configured for engagement with a tape drive support. The take up core (220) is sized and shaped such that it can be located in the internal volume (240) of the supply core (210). Refer to FIG. 2

A ribbon cassette includes a case, an ink ribbon, a first spool, a second spool, a rotating member, a clutch spring, and an engaging part. The ink ribbon has one end portion wound over the first spool and another end portion connected to the second spool. The rotating member is engaged with a first inner surface of the first spool. The clutch spring includes a coil like annular part attached to the rotating member, and an extension part extending from the annular part. The engaging part is positioned on a locus of rotation of the extension part. The first spool has a protrusion provided at a second inner surface of the first spool. The case-hole is in communication with an interior of the first spool, and has a portion overlapped with an entire circular region surrounded by a path of rotation of the tip end of the protrusion.
