ENSEMBLE DE LANGUETTE DE PRESSION POUR CASSETTE A BANDE

LANGUETTE DE PRESSION POUR CASSETTE A BANDE, ENSEMBLE DE LANGUETTE DE PRESSION 72 ET DE BOITIER DE CASSETTE 86 ET PROCEDES POUR FABRIQUER LA LANGUETTE DE PRESSION ET POUR MONTER LA LANGUETTE DE PRESSION DANS LE BOITIER DE CASSETTE. LA LANGUETTE DE PRESSION 72 EST EN UNE MATIERE FLEXIBLE AYANT UN FAIBLE COEFFICIENT DE FROTTEMENT. UNE EXTREMITE DE LA LANGUETTE 76 COMPORTE DEUX RAINURES PERPENDICULAIRES ET PARALLELES 78, 80. LA LANGUETTE EST FIXEE DANS LE BOITIER DE CASSETTE 86 EN INTRODUISANT L'EXTREMITE NERVUREE ENTRE DEUX ELEMENTS SUPPORTS ADJACENTS 90, 96 FORMES DANS LE BOITIER DE CASSETTE. CETTE INVENTION ELIMINE LE RELACHEMENT DE LA BANDE ET LES INCONVENIENTS DES LANGUETTES DE PRESSION ANTERIEURES, QU'ELLES SOIENT FIXEES PAR ADHESIF OU NON. EN OUTRE, ELLE PROCURE UN PROCEDE DE FABRICATION ET UNE PROCEDURE D'INTRODUCTION AYANT UN MEILLEUR RENDEMENT ET PERMET UNE INTRODUCTION AUTOMATIQUE DE LA LANGUETTE DE PRESSION DANS LE BOITIER DE CASSETTE. A tape cassette pressure flap and pressure flap/cassette housing assembly and related methods for manufacturing the pressure flap and for assembling the pressure flap in the cassette housing. The pressure flap is generally flat and made of a flexible material. The flap has a first free end with a low coefficient of friction for normally urging a tape portion into contact with a guide member of the cassette housing so as to minimize slackness of the tape, and a second end for being fixedly attached to the cassette housing. At least one angled rectangular flange is formed at the fixed end. The fixed end is then inserted between at least one wall and a columnar support member formed in the cassette housing such that the pressure flap cannot be pushed out of position relative to the tape upon which it resiliently abuts. The at least one angled flange formed in the fixed end of the pressure flap abuts a columnar supporting member. This pressure flap and pressure flap/cassette housing assembly eliminates slackness and the disadvantages of the prior art adhesive-type and non-adhesive-type pressure flaps. Moreover, it provides a more efficient manufacturing process and inserting procedure and increased efficiency during automated insertion of the pressure flap into the cassette housing.
