Abstract

Abstract ABSTRACT OF DISCLOSURE A tape cassette for a magnetic recording and/or reproducing apparatus has a housing formed with an opening through which the tape can be withdrawn from the cassette housing for the recording or reproducing of signals thereon, as by one or more rotary magnetic heads, and a lid is provided to normally close the housing opening when the cassette is not in use and thereby protect the tape from damage thereto. The cassette housing is provided with guides thereon extending at right angles to each other, for example, parallel to the relatively long and short sides of the cassette housing when the latter is rectangular, for the purpose of guiding the cassette into a holder therefor in either of the directions parallel to the long and short sides, respectively, of the housing. A latch mechanism is provided for locking the lid in its closed position, and such latch mechanism is releasable in response to the insertion of the cassette into a holder in either of the foregoing directions. Locating members are provided on the cassette housing, pre-ferably as integral extensions of the bottom wall, and extend through corresponding cutouts in the lid for engagement with respective abutments provided on the holder so as to accurately locate the cassette in respect to the holder while avoiding interference with the opening of the lid. The lid is provided with one or more interior partitions extending parallel to the front wall of the lid to define a channel which, in the closed position of the lid, accommodates the run of the tape extending across the opening of the cassette housing for preventing contact with such run of the tape through the cassette opening.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 226 words
A tape cassette comprising a housing of generally rectangular configuration containing a supply of tape and having top and bottom walls and a peripheral wall extending between said top and bottom walls along three of the sides of the latter so as to leave an opening along the fourth side of the housing through which the tape can be withdrawn, said tape cassette being insertable into a cassette holder which is moved downwardly from its raised position to its lowered operative position to withdraw said tape; a lid pivoted on said housing for movement between a closed position in which a front portion of said lid extends along said fourth side of the housing and covers said opening, and an opened position in which said front portion of said lid is raised relative to said housing for exposing said opening; and a cutout in said bottom wall opening at said fourth side of the housing in back of said front portion of the lid in said closed position so that a lid opening member, which is engageable upwardly against the lower edge of said front portion for raising the latter and thereby moving the lid to its opened position in the course of the downward movement of the cassette holder, can extend at least partly into said cutout when engaging said front portion of the lid.
Claim 2
Dependent Claim 226 words
A tape cassette comprising a housing of generally rectangular configuration containing a supply of tape and having top and bottom walls and a peripheral wall extending between said top and bottom walls along three of the sides of the latter so as to leave an opening along the fourth side of the housing through which the tape can be withdrawn, said tape cassette being insertable into a cassette holder which is moved downwardly from its raised position to its lowered operative position to withdraw said tape; a lid pivoted on said housing for movement between a closed position in which a front portion of said lid extends along said fourth side of the housing and covers said opening, and an opened position in which said front portion of said lid is raised relative to said housing for exposing said opening; and a cutout in said bottom wall opening at said fourth side of the housing in back of said front portion of the lid in said closed position so that a lid opening member, which is engageable upwardly against the lower edge of said front portion for raising the latter and thereby moving the lid to its opened position in the course of the downward movement of the cassette holder, can extend at least partly into said cutout when engaging said front portion of the lid.
Claim 3
Dependent Claim 55 words
A tape cassette according to claim 1, wherein said housing comprises two tape guide members positioned at opposite sides of said opening in said bottom wall for guiding said tape along said fourth side, said cutout in said bottom wall being formed between one of said guide members and an end of said fourth side.
Claim 4
Dependent Claim 30 words
A tape cassette according to claim 2, wherein said bottom wall has corners at opposite ends of said fourth side and said cutout is formed adjacent one of said corners.
