Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
139 words
A cartridge arrangement for permitting a relatively small cartridge containing at least one pack of tape-like recording medium to be used on a recording and/or playback apparatus designed for use with a relatively large cartridge, each said cartridge comprising two sections, hinge means pivotally connecting said sections together, and an automatically releasable locking member, and said apparatus having pivoting means for causing said sections to be spread apart, said arrangement comprising: an adapter frame dimensioned on the inside to receive said relatively small cartridge, having outside dimensions generally corresponding to those of the relatively large cartridge, and being provided with means for retaining said small cartridge as well as means carried by said retaining means and cooperating with the relatively short locking member of said small cartridge for releasing said cartridge upon insertion of said cartridge into said frame.
Claim 2
Dependent Claim
