Abstract
Abstract The tape cartridge is of the type utilized in automobile tape playback systems. The cartridge comprises a rotatable spool having a reel of magnetic tape in endless array. The spool is enclosed and rotatably mounted within a casing. The casing includes a base and a cover for the base. Lug means are provided on the base. Snap action fastening means are provided on the cover to engage the lug means. The snap action fastening means comprise a plurality of resilient blades arranged around the interior periphery of the cover and are spaced from the cover and extend generally parallel thereto. The blades resiliently engage the lug means to secure the cover to the base. Guide means are provided in the casing over which the loop portion of the tape passes for transportation past a reproducing head. The guide means result in positive guiding of the tape to assure accurate reproduction.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
171 words
In a tape cartridge containing a rotatable spool having a reel of magnetic tape in endless array, a casing enclosing and mounting the spool, said casing comprising a base and a cover therefor, guide means in the casing over which the loop portion of the tape is positively guided for transportation past a reproducing head snap action fastening means on the cover, said snap action fastening means comprising a plurality of resilient elongated blades spaced from the cover, said blades being spaced from each other around a central portion of the cover, a post extending from the cover to support each blade, each post having a generally teardrop shape, the portion of the blade extending immediately therefrom at the juncture thereof being enlarged thereby to provide for flexing of the blade along the length thereof, and a plurality of lugs on the base, one lug being provided between each blade and the cover, each lug being in pressure contact with an edge of its respective blade to frictionally engage the blade.
Claim 2
Dependent Claim
171 words
In a tape cartridge containing a rotatable spool having a reel of magnetic tape in endless array, a casing enclosing and mounting the spool, said casing comprising a base and a cover therefor, guide means in the casing over which the loop portion of the tape is positively guided for transportation past a reproducing head snap action fastening means on the cover, said snap action fastening means comprising a plurality of resilient elongated blades spaced from the cover, said blades being spaced from each other around a central portion of the cover, a post extending from the cover to support each blade, each post having a generally teardrop shape, the portion of the blade extending immediately therefrom at the juncture thereof being enlarged thereby to provide for flexing of the blade along the length thereof, and a plurality of lugs on the base, one lug being provided between each blade and the cover, each lug being in pressure contact with an edge of its respective blade to frictionally engage the blade.
Claim 3
Dependent Claim
79 words
A cartridge as defined in claim 1, and further characterized in the provision of at least three resilient blades, one lug being provided for each of the blades, one of said lugs being supported by a wall extending laterally across the base, each of the other of said lugs being supported by a wall extending at an angle to said laterally extending wall and diverging from each other, the respective blades being generally parallel to the lug supporting walls.
Claim 4
Dependent Claim
46 words
A cartridge as defined in claim 1, and further characterized in the provision of a spokelike wall structure extending from the cover, and notch means provided in the base receiving said spokelike wall means to lock the cover and base against relative twisting or lateral movement.
Claim 5
Dependent Claim
64 words
A cartridge as defined in claim 1, and further characterized in that the guide means in the casing over which the loop portion of the tape is positively guided for transportation past a reproducing head comprises a plurality of guide slot structures each including upper and lower guide surfaces and side guide surfaces to position the tape properly with respect to the reproducing head.
Claim 6
Dependent Claim
39 words
A cartridge as defined in claim 1, and further characterized in the provision of a hub on the base rotatably receiving the spool, and an arcuate ringlike projection structure on the base serving as a bearing for the spool.
Claim 7
Dependent Claim
65 words
A cartridge as defined in claim 1, and further characterized in that said spool includes a hollow cylindrical projection extending beyond the reel of magnetic tape, a pair oF hollow concentric cylindrical wall structures extending from the cover and receiving therebetween but not touching said hollow projection of the spool to act as a guide and stop structure for the spool and reel of tape.
Claim 8
Dependent Claim
46 words
A cartridge as defined in claim 6, and further characterized in the provision of a projection on the cover in alignment with the center of the spool to act as a stop member to limit axial movement of the spool on the hub of the base.
