[Problem] To achieve a ribbon supply shaft with which subtle positional adjustment of a restriction member can be performed, and with which positional displacement does not readily occur. [Solution] The present invention is provided with: a pair of first engagement-groove rows (91c, 91d) comprising a plurality of consecutive grooves (61c, 61d) which are provided in rows along an axial direction of a holding shaft (91), which extend in a direction intersecting the axial direction of the support shaft (91), and which are formed in orthogonal surfaces (81c, 81d) orthogonal with respect to the axial direction of the holding shaft (91), and in inclined surfaces (71c, 71d) along the axial direction of the holding shaft (91), said inclined surfaces being inclined in mutually opposite directions; and second engagement-groove rows (92c, 92d) which are formed in a pair of lock members (92x, 92y) provided to a restriction member (92) to be fitted to the holding shaft (91), and which are provided with surfaces corresponding to surfaces formed in the pair of first engagement-grove rows (91c, 91d). |
