Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
184 words
A magazine for magnetic tape cassets, comprising a trough which is U-shaped in cross section and possesses a plurality of transverse ribs on the bottom, the ribs being arranged at intervals corresponding to the thickness of a magnetic tape cassette, said trough is open at both ends and the two side members of the trough project above the inserted magnetic tape cassettes, said trough is designed so the two side members are capable of being resiliently bent apart for insertion of said cassets and are each provided on their inner surfaces over their entire length and nearly their entire height with a strip of resilient material, the clear width between the side members as covered by said strips being smaller, by an amount about equal to the reduction in the thickness of the strips in the compressed state, than the relevant dimension of the magnetic tape cassettes which are to be inserted, such that the cassettes, upon insertion into the magazine, are held for storage, in any attitude of said magazine, due to the combined holding action of said side members of said strips.
Claim 2
Dependent Claim
