Abstract
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.
