ABSTRACT:
A low cost video cassette has a base formed of a generally flat wall portion, with sloped converging front walls spaced inward from a front edge and with flat tape guiding walls extending upward from medial, generally rectangular projections of the base. Tape guide roller support pins are mounted on forward projections near lateral portions of the base. Tape reel guides are molded in the base. Integrally formed tape reel locks have operators extending into a groove formed in the plane of the base for receiving an actuator which extends into, but not beyond, the plane of the base. The rear wall has an upward-extending recess and a frangible anti-record tab extending downward within the recess. Rectangular openings are formed medially in the cover. Flaps are hinged to the openings. Cantilevered leaf springs connected along outer edges of the openings or to the flaps extend toward the base wall when the flaps close the openings to urge tape reels downward. A dust cover is connected to the short living springs. A spring connected to the cover and connected to another portion of the cassette holds the cover at a generally downward position. A latch integrally formed on a living hinge has an outward actuator-receiving portion for releasing the latch, and a parallel outward-extending latching portion for engaging an inner ledge on an inner end of a side wall of the dust wall. The latch has an upward extension for engaging an inner surface of the dust door and moving the latch outward as the dust door is closed.
