Abstract
Abstract A tape cartridge for a tape recording system is described having a rectangular housing for rotatably supporting a pair of standard reels. The cartridge includes a cover which can be removed to permit access to the interior of the housing to repair the magnetic tape or remove the reels. The cartridge is adapted to expose the tape to capstan and magnetic head assemblies while permitting drive means to be inserted within the housing to engage the take-up and supply reels.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
143 words
A tape cartridge for receiving a supply reel and a takeup reel comprising: a cartridge housing formed by a bottom wall and peripheral side walls; means on said bottom wall for rotatably supporting the supply reel and the takeup reel; a pair of apertures formed in one of said side walls for receiving supply and takeup reel drive means; and brake means adapted to frictionally engage the peripheries of the supply and takeup reels for locking said reels during nonuse, said brake means further comprising trigger means adapted to be contacted by either of said rEel drive means for releasing said brake means, said brake means further comprising a pair of arms pivotally mounted on said bottom wall, one end of each arm including a shoe having a friction pad located therein for frictionally engaging the peripheries of the supply and takeup reels.
Claim 2
Dependent Claim
143 words
A tape cartridge for receiving a supply reel and a takeup reel comprising: a cartridge housing formed by a bottom wall and peripheral side walls; means on said bottom wall for rotatably supporting the supply reel and the takeup reel; a pair of apertures formed in one of said side walls for receiving supply and takeup reel drive means; and brake means adapted to frictionally engage the peripheries of the supply and takeup reels for locking said reels during nonuse, said brake means further comprising trigger means adapted to be contacted by either of said rEel drive means for releasing said brake means, said brake means further comprising a pair of arms pivotally mounted on said bottom wall, one end of each arm including a shoe having a friction pad located therein for frictionally engaging the peripheries of the supply and takeup reels.
Claim 3
Dependent Claim
47 words
The invention of claim 1 wherein said brake means further comprises spring means for biasing said arms against the reels and said trigger means being movably mounted adjacent said arms for pivoting said arms away from the reels when contacted by either of said reel drive means.
Claim 4
Dependent Claim
36 words
The invention of claim 2 wherein said trigger means further comprises a pair of lever arms extending toward said pair of apertures and through a second pair of orifices for engagement with said reel drive means.
Claim 5
Dependent Claim
57 words
The invention of claim 3 wherein said lever arms converge to form a boss portion, and said brake arms further comprise a pair of extensions extending from the pivotal axes of said arms and converging to contact said boss portion for pivoting said brake arms away from the reels upon a downward movement of said boss portion.
Claim 6
Dependent Claim
132 words
A tape cartridge for receiving a supply reel and a takeup reel having a quantity of tape mounted thereon comprising: a cartridge housing formed by a bottom wall and peripheral side walls; means on said bottom wall for rotatably supporting the supply reel and the takeup reel; and a pair of orifice means formed on two of the opposing side walls for defining an optical light transmission path cutting across the supply reel tangential to the hub thereof when the tape is substantially removed from the supply reel, said orifice means being adapted to cooperate with a photoelectric system on a tape transport to monitor the amount of tape on the supply reel by creating a light signal through the optical path when the tape is unwound below the light transmission path.
Claim 7
Dependent Claim
132 words
A tape cartridge for receiving a supply reel and a takeup reel having a quantity of tape mounted thereon comprising: a cartridge housing formed by a bottom wall and peripheral side walls; means on said bottom wall for rotatably supporting the supply reel and the takeup reel; and a pair of orifice means formed on two of the opposing side walls for defining an optical light transmission path cutting across the supply reel tangential to the hub thereof when the tape is substantially removed from the supply reel, said orifice means being adapted to cooperate with a photoelectric system on a tape transport to monitor the amount of tape on the supply reel by creating a light signal through the optical path when the tape is unwound below the light transmission path.
Claim 8
Dependent Claim
31 words
The invention of claim 5 wherein the portions of the bottom and side walls adjacent said orifice means further comprise means for blackening said portions to be impervious to outside light.
Claim 9
Dependent Claim
91 words
The invention of claim 1 further comprising a pair of orifice means formed on two of the opposing side walls for defining an optical light transmission path cutting across the supply reel tangential to the hub thereof when the tape is substantially removed from the supply reel, said orifice means being adapted to cooperate with a photoelectric system on a tape transport to monitor the amount of tape on the supply reel by creating a light signal through the optical path when the tape is unwound below the light transmission path.
Claim 10
Dependent Claim
31 words
The invention of claim 7 wherein the portions of the bottom and side walls adjacent said orifice means further comprise means for blackening said portions to be impervious to outside light.
