Abstract
Abstract The endless magnetic tape cartridge described contains a single reel of tape in spiral array on a rotatable platform. When in play operation, the inner turns are withdrawn causing the reel to rotate with the platform. The tape is transported beyond the transducer and thereupon presented as outer turns onto the reel. The housing of the cartridge is constructed of a mating rectangular base and cover, of tough molded material. Arrangements are herein provided along the sidewalls of the base and cover to maintain their assembly stable despite rough handling or drop onto a hard floor.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
135 words
A cartridge for a rotatable coil of tape in endless configuration, constructed with a housing enclosing therein the tape coil, a pinch roller and a guidepost, a loop portion of the tape extending around the guidepost and pinch roller for its transcription action, said housing comprising a base section and a cover section each of molded material, said sections being formed with sidewalls that project towards each other and mate therealong, said base section having a plurality of socket-posts extending integrally upwards from its interior region to respectively rotatably carry said tape coil and pinch roller and one of which forms said guidepost, said cover section having integral pins respectively extending into openings centrally of said socket-posts, said pins and socket-posts being arranged as pairs that interlock and thereby firmly secure the cartridge sections together.
