Abstract:
1. A label cassette comprising: a housing having a base and a top; a first opening in the base; a second opening in the top; and a locking member positioned inside the housing, said locking member comprising at least one guide rib extending on an inner surface of said locking member from a lower portion of said locking member towards an upper portion of said locking member, said locking member comprising a central axis extending in a direction from said lower portion of said locking member to said upper portion of said locking member and at least one projection on an inner surface of the locking member, the projection having a sloped surface, said sloped surface in a plane that projects outwardly from said inner surface of said locking member towards said central axis, configured to abut a correspondingly sloped surface on and thereby cause rotational movement of a locking part of a cassette-receiving bay of a label printer about said central axis of said locking member, as said correspondingly sloped surface on said locking part of said label printer passes over said sloped surface of said projection during insertion of the cassette in the label printer, the locking member comprising a second surface configured to engage a surface of the locking part of the cassette receiving bay of the label printer and thereby prevent movement of said cassette in a direction parallel to said central axis of the locking member after correct insertion of said cassette in said label printer, wherein a plane of the second surface of the projection is perpendicular to said central axis.
