Abstract

Abstract A tape cartridge having a supply and takeup reel in which the reels can be located so as to vary the distance between them. An adapter fits around the periphery of the tape cartridge which permits the cartridge to be used in both large and small enclosures. The reels are adjustable to be accommodated on spindles which are relatively proximate or distal in the small and large enclosures respectively.

Claims Analysis

Total Claims: 19
Claim 1
Independent Claim 53 words
In a tape cartridge adapted for use with a tape recorder comprising, a. a supply reel and a takeup reel which are spaced apart, for receiving and holding a magnetic tape, b. a housing holding said reels and having means thereon for selectively varying the distance between said spaced supply and takeup reels.
Claim 2
Dependent Claim 53 words
In a tape cartridge adapted for use with a tape recorder comprising, a. a supply reel and a takeup reel which are spaced apart, for receiving and holding a magnetic tape, b. a housing holding said reels and having means thereon for selectively varying the distance between said spaced supply and takeup reels.
Claim 3
Dependent Claim 41 words
In a tape cartridge adapted for use with a tape recorder as defined in claim 1 further comprising a boss on each reel which serves to maintain said reels in the means for selectively varying the distance between said spaced reels.
Claim 4
Dependent Claim 49 words
In a tape cartridge adapted for use with a tape recorder as defined in claim 1 further comprising adapter means to conform at least one dimension of said housing with a tape recorder having a tape cartridge receiving opening therein thereby enabling said cartridge to fit within said opening.
Claim 5
Dependent Claim 34 words
In a tape cartridge adapted for use with a tape recorder as defined in claim 1 in which said means for selectively varying the distance between said reels comprises said housing having apertures therein.
Claim 6
Dependent Claim 20 words
In a tape cartridge as defined in claim 4 in which said apertures are elongated and their longitudinal axes intersect.
Claim 7
Dependent Claim 92 words
In a tape cartridge adapted for use with a tape recorder comprising, a. a supply reel and a takeup reel which are spaced apart for receiving and holding a magnetic tape, b. a housing enclosing said reels and having means therein for maintaining them in a predetermined spaced relationship, c. at least one removable member on said housing for selectively allowing or preventing the insertion of an actuating member on said tape recorder which actuates the power supply for said tape recorder thereby preventing the accidental erasure of a recorded magnetic tape.
Claim 8
Dependent Claim 92 words
In a tape cartridge adapted for use with a tape recorder comprising, a. a supply reel and a takeup reel which are spaced apart for receiving and holding a magnetic tape, b. a housing enclosing said reels and having means therein for maintaining them in a predetermined spaced relationship, c. at least one removable member on said housing for selectively allowing or preventing the insertion of an actuating member on said tape recorder which actuates the power supply for said tape recorder thereby preventing the accidental erasure of a recorded magnetic tape.
Claim 9
Dependent Claim 44 words
In a tape cartridge adapted for use with a tape recorder as defined in claim 7 in which two spaced removable members are located on said housing which members can be removed from said housing upon retracting said tape cartridge from said tape recorder.
Claim 10
Dependent Claim 53 words
An adapter for use with a tape cartridge and a power supply comprising, a. a member having at least two legs of a predetermined thickness adapted to be removably attached to a tape cartridge, whereby said legs adapt said tape cartridge to be used with said power units having various sized cartridge-receiving openings.
Claim 11
Dependent Claim 53 words
An adapter for use with a tape cartridge and a power supply comprising, a. a member having at least two legs of a predetermined thickness adapted to be removably attached to a tape cartridge, whereby said legs adapt said tape cartridge to be used with said power units having various sized cartridge-receiving openings.
Claim 12
Dependent Claim 44 words
An adapter for use with a tape cartridge and a power unit as defined in claim 8 in which said adapter further comprises a bight connecting said legs so as to form a U-shaped member which conforms to three sides of said tape cartridge.
Claim 13
Dependent Claim 38 words
An adapter for use with a tape cartridge and a power unit as defined in claim 8 in which said adapter further comprises a resilient detent on each leg to firmly maintain said legs on said tape cartridge.
Claim 14
Dependent Claim 51 words
An adapter for use with a tape cartridge and a power unit as defined in claim 8 in which said adapter further comprises a spring biased lever fixed to each leg in which one end of the lever has a portion thereon adapted to engage in an opening on said cartridge.
Claim 15
Dependent Claim 39 words
In a tape cartridge as defined in claim 1 in which said means for selectively varying the distance between the reels comprises, a. said housing having a pair of spaced elongated apertures thereon the form of the figure ''''8.''''
Claim 16
Dependent Claim 32 words
In a tape cartridge as defined in claim 12 further comprising means located between the oval portions of said figure ''''8'''' for preventing a reel from moving from one oval to another.
Claim 17
Dependent Claim 54 words
In a tape cartridge as defined in claim 13 in which said means comprises a resilient tang depending from an opening in the housing in which pressure exerted by said reel on said tang will bend the tang and thereby permit said reel to move from one oval of said figure ''''8'''' to another.
Claim 18
Dependent Claim 45 words
In a tape cartridge as defined in claim 1 in which said supply and takeup reels each have an arm rotatably mounted thereon in which said arm moves the respective reel to a fixed position as a result of being actuated by an external member.
Claim 19
Dependent Claim 40 words
In a tape cartridge as defined in claim 15 further comprising an adapter having a pair of depending arms thereon in which said depending arms actuate said arms in said reels when said adapter is placed on said tape cartridge.
