  • Cassette case and index sheet
    Patent number: 5186325
    Abstract: A cassette case is constructed such that a tape cassette is supported to a lid side by utilizing guiding protrusions provided on the side portions of the tape cassette. Also, a recess portion is formed on the inner surface of the casing so as to accommodate therein a thick portion which forms a front opening portion of the tape cassette, thereby a thickness of the entirety of the cassette case being reduced. Further, in an index sheet inserted into the cassette case, a portion corresponding to the recess portion formed in the inside of the casing is formed as a recess-shaped portion, and thus this index sheet is suitably applied to the above-mentioned thin cassette case.
