Abstract
Abstract A magnetic tape carrier has a supply reel and a take-up reel on which a magnetic tape is wound, a tape guide for guiding the tape from the supply reel to the take-up reel, a first reel mount on which the supply reel is rotatably mounted, a second reel mount on which the take-up reel is rotatably mounted, and a holder for movably supporting the first mount and second mount. The magnetic carrier can thus be used for various magnetic tape apparatus having different distances between the reel drive shafts of the supply reel and the take-up reel.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
136 words
A magnetic tape carrier comprising: a supply reel and a take-up reel on which a magnetic tape is wound; a tape guiding means for guiding the tape from said supply reel to said take-up reel; first mounting means on which said supply reel is rotatably mounted; second mounting means on which said take-up reel is rotatably mounted; and a holder on which said first mounting means and said second mounting means are movably mounted for movement independently of each other between positions in which the reels are fixedly positioned close to each other at a center distance between said two reels of l 1 and positions in which the reels are fixedly positioned relatively far from each other at a center distance between said two reels of l 2 which is larger than l 1 .
Claim 2
Dependent Claim
136 words
A magnetic tape carrier comprising: a supply reel and a take-up reel on which a magnetic tape is wound; a tape guiding means for guiding the tape from said supply reel to said take-up reel; first mounting means on which said supply reel is rotatably mounted; second mounting means on which said take-up reel is rotatably mounted; and a holder on which said first mounting means and said second mounting means are movably mounted for movement independently of each other between positions in which the reels are fixedly positioned close to each other at a center distance between said two reels of l 1 and positions in which the reels are fixedly positioned relatively far from each other at a center distance between said two reels of l 2 which is larger than l 1 .
Claim 3
Dependent Claim
56 words
A magnetic tape carrier according to claim 1 in which said first mounting means and said second mounting means are hollow casings, each of which is adapted to have a corresponding one of said two reels rotatably mounted therein and which is pivotally supported on said holder for pivotal movement independently of the other hollow casing.
Claim 4
Dependent Claim
26 words
A magnetic tape carrier according to claim 2, wherein said holder is provided with a positioning hole for positioning said tape carrier at a predetermined position.
Claim 5
Dependent Claim
46 words
A magnetic tape carrier according to claim 2 in which said first mounting means and said second mounting means have opposed side walls contacting each other when the mounting means are in the position where the center distance between said two reels is l 1 .
Claim 6
Dependent Claim
26 words
A magnetic tape carrier according to claim 4, wherein said holder is provided with a positioning hole for positioning said tape carrier at a predetermined position.
Claim 7
Dependent Claim
26 words
A magnetic tape carrier according to claim 1, wherein said holder is provided with a positioning hole for positioning said tape carrier at a predetermined position.
Claim 8
Dependent Claim
167 words
In combination: a cassette casing; a magnetic tape carrier in said casing and comprising: a supply reel and a take-up reel on which a magnetic tape is wound; a tape guiding means for guiding the tape from said supply reel to said take-up reel; first mounting means on which said supply reel is rotatably mounted; second mounting means on which said take-up reel is rotatably mounted; and a holder on which said first mounting means and said second mounting means are movably mounted for movement independently of each other between first positions in which the reels are fixedly positioned close to each other at a center distance between said two reels of l 1 and second positions in which the reels are fixedly positioned relative far from each other at a center distance between said two reels of l 2 which is larger than l 1 , said holders being in said first positions; and means in said cassette casing positioning said holders in said first positions.
Claim 9
Dependent Claim
167 words
In combination: a cassette casing; a magnetic tape carrier in said casing and comprising: a supply reel and a take-up reel on which a magnetic tape is wound; a tape guiding means for guiding the tape from said supply reel to said take-up reel; first mounting means on which said supply reel is rotatably mounted; second mounting means on which said take-up reel is rotatably mounted; and a holder on which said first mounting means and said second mounting means are movably mounted for movement independently of each other between first positions in which the reels are fixedly positioned close to each other at a center distance between said two reels of l 1 and second positions in which the reels are fixedly positioned relative far from each other at a center distance between said two reels of l 2 which is larger than l 1 , said holders being in said first positions; and means in said cassette casing positioning said holders in said first positions.
Claim 10
Dependent Claim
167 words
In combination: a cassette casing; a magnetic tape carrier in said casing and comprising: a supply reel and a take-up reel on which a magnetic tape is wound; a tape guiding means for guiding the tape from said supply reel to said take-up reel; first mounting means on which said supply reel is rotatably mounted; second mounting means on which said take-up reel is rotatably mounted; and a holder on which said first mounting means and said second mounting means are movably mounted for movement independently of each other between first positions in which the reels are fixedly positioned close to each other at a center distance between said two reels of l 1 and second positions in which the reels are fixedy positioned relatively far from each other at a center distance between said two reels of l 2 which is larger than l 1 , said holders being in said second positions; and means in said cassette casing positioning said holders in said second positions.
