ABSTRACT:
In a machine which uses cassettes, a compartment is provided for receiving the cassette. Examples of such machines are printing machines using an inked ribbon cassette. In the compartment there is a V-shaped toggle spring which is pivotally mounted at its vertex with two arms and extending forward so that when a cassette is inserted and pushed in against both arms, the latter are splayed apart and the spring pivots and snaps the cassette into a "home" position in which it is retained by a cooperating means on the cassette and the compartment.
