Abstract
A tape cartridge having a housing structure. The housing structure includes a base plate and a cover having an open-ended box shape and secured to the base plate. The cover includes a top wall, a front wall and a side wall which extend substantially perpendicular to each other to define a corner portion of the cover. A notch is formed at the corner portion of the cover to be thereby prevented from failing to be detected.
Claims3
A tape cartridge including a housing accommodating therein two rotatable tape reels, a magnetic recording tape wound on the tape reels, a plurality of tape guides, an endless drive belt engaging the tape, a belt driving roller around which the drive belt is wrapped, said housing comprising:
- a base plate;
- a cover secured to said base plate, said cover having an open-ended box shape and including therein first, second and third plane walls which extend substantially perpendicular to each other to define a corner portion of said cover;
- and
- means for preventing inadvertent writing on the magnetic recording tape by a tape recording/reproducing apparatus comprising a notch defined at the corner portion of said cover by:
- a first wall portion which is mutually perpendicular to said first and second plane walls, and
- a second wall portion which is mutually perpendicular to said first and third plane walls, said second wall portion intersecting said first wall portion at a predetermined angle to form a corner line of said notch which is normal to said first plane wall and parallel with said second and third plane walls.
A tape cartridge including a housing accommodating therein two rotatable tape reels on which a magnetic recording tape is wound and which are driven by an endless drive belt, comprising:
- a box-shaped cover secured to a base plate, said box-shaped cover including a top plane wall and first and second side walls which extend substantially perpendicular to each other and which meet to define a corner portion of said cover;
- and
- means for preventing inadvertent writing on the magnetic recording tape by a tape recording/reproducing apparatus, comprising a constantly exposed notch which removes a portion of each of said top wall and said first and second walls respectively, and which is so configured as to prevent ready masking.
