Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 307 words
In combination, a pair of magnetic tape microcassettes and a magnetic tape cassette holder for receiving a pair of said tape microcassettes and for holding the tape microcassettes in their respective operable conditions without requiring removal from the holder; each tape microcassette including: a pair of tape hubs exposed outside the holder, a capstan insertion hole extending therethrough, cassette positioning holes formed at one surface thereof, a magnetic tape fixed at its ends to the hubs and adapted to run between the hubs, an open front end exposing the magnetic tape and a closed rear end opposite the front end; and said magnetic cassette holder comprising: a one-piece molded synthetic resin body having a pair of cassette receiving and holding chambers located adjacent each other in the same plane, said body having upper and lower panels which are dished toward each other and forming upper and lower surfaces of said chambers, said dished panels being adapted to elastically hold microcassettes therebetween, each chamber having an opening through which a respective microcassette is inserted, the microcassettes being received in their respective chambers in rear end-to-rear end relationship in the same plane, between said dished panels, said chambers further having at least one cutout for permitting all of the hubs, capstan insertion hole, and cassette positioning holes of a microcassette received in a chamber to be exposed for operation of the microcassette, and a stop member located between said pair of holding chambers and which is engageable with inserted microcassettes to limit insertion of said microcassettes into a chamber of the holder such that the front ends of the mirocassettes are operably exposed and said hubs, capstan insertion hole and cassette positioning holes are all operably exposed, whereby the microcassettes are held in said holder in their respective operable conditions without requiring removal from the holder for operation thereof.
Claim 2
Dependent Claim 307 words
In combination, a pair of magnetic tape microcassettes and a magnetic tape cassette holder for receiving a pair of said tape microcassettes and for holding the tape microcassettes in their respective operable conditions without requiring removal from the holder; each tape microcassette including: a pair of tape hubs exposed outside the holder, a capstan insertion hole extending therethrough, cassette positioning holes formed at one surface thereof, a magnetic tape fixed at its ends to the hubs and adapted to run between the hubs, an open front end exposing the magnetic tape and a closed rear end opposite the front end; and said magnetic cassette holder comprising: a one-piece molded synthetic resin body having a pair of cassette receiving and holding chambers located adjacent each other in the same plane, said body having upper and lower panels which are dished toward each other and forming upper and lower surfaces of said chambers, said dished panels being adapted to elastically hold microcassettes therebetween, each chamber having an opening through which a respective microcassette is inserted, the microcassettes being received in their respective chambers in rear end-to-rear end relationship in the same plane, between said dished panels, said chambers further having at least one cutout for permitting all of the hubs, capstan insertion hole, and cassette positioning holes of a microcassette received in a chamber to be exposed for operation of the microcassette, and a stop member located between said pair of holding chambers and which is engageable with inserted microcassettes to limit insertion of said microcassettes into a chamber of the holder such that the front ends of the mirocassettes are operably exposed and said hubs, capstan insertion hole and cassette positioning holes are all operably exposed, whereby the microcassettes are held in said holder in their respective operable conditions without requiring removal from the holder for operation thereof.
Claim 3
Dependent Claim 31 words
The combination of claim 1, wherein said cassette holder is fabricated of a substantially rigid material, the dished panels being resilient so as to yield upon insertion of a microcassette therebetween.
