Ribbon cassette having openable and closeable lid members

摘要

A ribbon cassette includes a lid member that is not abruptly opened when a cassette is loaded into a printing apparatus and/or a facsimile apparatus using the ribbon cassette. Retained parts are provided on both side faces of a supplying part main body of a ribbon supplying part in a ribbon cassette and retaining parts which are detachably engaged with the retained parts to retain a lid member by the supplying part main body are provided on side faces of the lid member. While each of the retained parts is a protrusion projecting sideward, each of the retaining parts on the side faces of the lid member via a hinge part and has an engagement hole with which the protrusion is detachably engaged. The ribbon supplying part has engaged parts provided near the retained parts and engagement projecting parts which are provided near the retaining parts and detachably engaged with the retained parts, thereby constructing the engagement relation countering the force acting in the direction of cancelling the retaining relation between the retained parts and the retaining parts.
