ABSTRACT:
An improved video tape cassette is molded from a plastic having good elastic memory in primarily two pieces, namely a housing piece and a dust cover piece. The housing is provided with an inwardly movable latching flap which holds the dust cover in latched position, and which is backed up by an integrally molded spring. A second spring is integrally molded to the dust cover to bias it in a closed position. Rotatable guide sleeves are provided to reduce tape damage, and locking teeth keep the spools from moving when the cassette is not in a video player/recorder machine.
