Abstract
Abstract In a cartridge adapter in which torque is transmitted from the capstan of the tape recorder to the tape in the small-sized tape cartridge by means of an idler and a driving idler, the idler and the driving idler may be mounted on flexible shafts positioned so that they are forced into firm contact with each other by the pressure of the tape recorder capstan against the idler when the adapter is in use, but are not touching or are just barely in contact when the adapter is in use, thereby avoiding the risk that they will produce permanent deformation to each other when the adapter is not in use.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
149 words
In a cartridge adapter having external dimensions and configuration of a large-size cartridge and mounting internally a small-size tape cartridge, and further having a pair of side by side idlers for transmitting by peripheral, frictional contact, torque from the capstan external of the cartridge adapter to the tape within the small-sized tape cartridge, the improvement wherein: at least said idler contacting said capstan is mounted on a resilient, flexible shaft and said idlers are positioned relative to each other such that when the adapter is in use, said capstan presses on said adjacent idler to flex its shaft and to move that idler into firm contact with said tape contacting said idler, and when said adapter is not in use and contact with said capstan ceases, there is no more than bare contact between said idlers, and said flexible shaft and one face of the adapter are molded integrally.
Claim 2
Dependent Claim
149 words
In a cartridge adapter having external dimensions and configuration of a large-size cartridge and mounting internally a small-size tape cartridge, and further having a pair of side by side idlers for transmitting by peripheral, frictional contact, torque from the capstan external of the cartridge adapter to the tape within the small-sized tape cartridge, the improvement wherein: at least said idler contacting said capstan is mounted on a resilient, flexible shaft and said idlers are positioned relative to each other such that when the adapter is in use, said capstan presses on said adjacent idler to flex its shaft and to move that idler into firm contact with said tape contacting said idler, and when said adapter is not in use and contact with said capstan ceases, there is no more than bare contact between said idlers, and said flexible shaft and one face of the adapter are molded integrally.
Claim 3
Dependent Claim
22 words
The cartridge adapter of claim 1, wherein said flexible shaft fits loosely into a bearing on the opposite face of the adapter.
Claim 4
Dependent Claim
129 words
In a cartridge adapter having external dimensions and configuration of a large-size cartridge and mounting internally a small-size tape cartridge, and further having a pair of side by side idlers for transmitting by peripheral, frictional contact, torque from the capstan external of the cartridge adapter to the tape within the small-size tape cartridge, the improvement wherein: both idlers are mounted on resilient, flexible shafts, and said idlers are positioned relative to each other such that when the adapter is in use, said capstan presses on said adjacent idler to flex its shaft and to move that idler into firm contact with said tape contacting idler, but when the adapter is not in use and contact with said capstan ceases, there is no more than bare contact between said idlers.
Claim 5
Dependent Claim
129 words
In a cartridge adapter having external dimensions and configuration of a large-size cartridge and mounting internally a small-size tape cartridge, and further having a pair of side by side idlers for transmitting by peripheral, frictional contact, torque from the capstan external of the cartridge adapter to the tape within the small-size tape cartridge, the improvement wherein: both idlers are mounted on resilient, flexible shafts, and said idlers are positioned relative to each other such that when the adapter is in use, said capstan presses on said adjacent idler to flex its shaft and to move that idler into firm contact with said tape contacting idler, but when the adapter is not in use and contact with said capstan ceases, there is no more than bare contact between said idlers.
Claim 6
Dependent Claim
19 words
The cartridge adapter of claim 3, wherein both said shafts and one face of the adapter are molded integrally.
Claim 7
Dependent Claim
22 words
The cartridge adapter of claim 4, wherein both said shafts fit loosely into respective bearings on the opposite face of the adapter.
