Abstract
A printer includes a casing, a cover, a ribbon cassette and a ribbon spool. The casing has a space and an opening. The cover is pivotally connected to the casing, and configured to close the opening. The cover has a protruding portion facing the space. The ribbon cassette is detachably accommodated in the space. The ribbon cassette includes elastic arms, at least one of which has a first hooking structure. The ribbon spool is detachably and pivotally connected to the ribbon cassette. The ribbon spool includes a second hooking structure. Before the cover closes the opening, the second and the first hooking structures are mutually locked. When the cover closes the opening, the protruding portion inserts between the elastic arms, such that the first hooking structure detaches from the second hooking structure, allowing rotational freedom of the ribbon spool relative to the ribbon cassette.
