Abstract
A tape cassette having a tape guide for contacting with a magnetic tape provided as a tape coil within a main cassette body, and guiding the running of the magnetic tape, is disclosed. The tape guide for guiding the magnetic tape is molded with a lower cassette half integrally from an ultra high molecular resin having a molecular weight ranging from 500,000 to 1,000,000 for simplifying the assembling process and reducing production costs as well as preventing adverse effects of deviation from true verticality of the tape guide on the magnetic tape during recording/reproduction or fast feed/rewind to assure stable tape running.
Claims4
A tape cassette in which a pair of tape reels are accommodated in a main cassette body formed by an upper cassette half and a lower cassette half abutted and connected to each other, and in which a magnetic tape is placed around said tape reels and adapted to be reeled out of said main cassette body by means of an aperture formed in the front side of said main cassette body,
- comprising the improvement of:
- a tape guide, provided within said main cassette body in the vicinity of said aperture for guiding said magnetic tape being reeled out of said aperture, is molded integrally with said lower cassette half, both said lower cassette half and said tape guide comprising an ultra high molecular synthetic resin material having a molecular weight ranging from 500,000 to 1,000,000.
