ABSTRACT:
A method of releasably attaching a filmstrip to the spool of a film cassette. The method includes inserting the filmstrip into a slot until an aperture in the filmstrip engages with a protrusion located in the slot of the spool. Subsequent withdrawal of the filmstrip is achieved by further inserting the filmstrip into the slot to disengage the aperture and the protrusion, moving the filmstrip in a direction transverse to the direction of insertion into the slot to misalign the aperture and the protrusion and then withdrawing the filmstrip from the slot in a direction which is reverse to that of insertion.
