Abstract
Abstract A cassette storage device retains cassettes in arcuately spaced relation for rotation about a horizontal axis which provides visual access with the cassettes being received in channels that confine end portions. Retention is affected by the use of the bosses on the cassette which are retained in slotted openings in web surfaces of the channels and releasability is achieved by the resiliency of the material which forms the holder.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
87 words
A recording tape cassette container comprising a base member presenting horizontally spaced trunion supporting surfaces formed about a horizontal axis; a cassette retaining holder including horizontally spaced trunion projections mounted on said base member supporting surfaces for rotation about a horizontal axis; spaced opposed channels including web and flange surfaces formed in said holder for receiving tape cassettes in angularly spaced, spoke-like relation about said horizontal axis; and retaining means in said opposed channel web surfaces for releaseably securing said cassettes respectively in said spaced, opposed channels.
Claim 2
Dependent Claim
87 words
A recording tape cassette container comprising a base member presenting horizontally spaced trunion supporting surfaces formed about a horizontal axis; a cassette retaining holder including horizontally spaced trunion projections mounted on said base member supporting surfaces for rotation about a horizontal axis; spaced opposed channels including web and flange surfaces formed in said holder for receiving tape cassettes in angularly spaced, spoke-like relation about said horizontal axis; and retaining means in said opposed channel web surfaces for releaseably securing said cassettes respectively in said spaced, opposed channels.
Claim 3
Dependent Claim
90 words
The recording tape cassette container of claim 1 wherein said holder comprises a pair of identical parts each formed of resilient material with a generally radially extending surface portion and a frustoconical axially extending portion with an end surface at the reduced diameter end thereof said generally radially extending surface portion having channels formed therein said pair of identical parts being secured together with said end surfaces bonded to one another with said channels of one of said parts respectively aligned with the channels of the other of said parts.
Claim 4
Dependent Claim
38 words
The recording tape cassette container of claim 2 wherein said pair of identical parts further include alignment means comprising a projection and recess in each of said end surfaces that cooperate to effect said alignment of said channels.
Claim 5
Dependent Claim
50 words
The recording tape cassette container of claim 3 further comprising formed end enclosure members which are secured to the axial ends of the assembly said identical parts to form said cassette holder, said end enclosure members including the axially extending horizontally spaced trunion projections formed as an integral portion thereof.
Claim 6
Dependent Claim
68 words
The recording tape cassette container of claim 4 wherein said cassette retaining holder comprises an assembly including two pairs of said identical parts secured to one another in pairs with said pairs axially aligned and bonded together along confronting surfaces of said generally radially extending surface portions and said end enclosure members are secured to said two pairs of identical parts at each axial end of said assembly.
Claim 7
Dependent Claim
61 words
The recording tape cassette container of claim 1 wherein said retaining means comprises a slotted recess centrally disposed in the web portion of each of said channels and said channel web and flange wall portions are formed of resilient material, whereby a substantially rigid cassette may be inserted or withdrawn and retained by cooperation of bosses thereon and said slotted recesses.
Claim 8
Dependent Claim
54 words
The recording tape cassette container of claim 6 wherein said aligned channels extend radially from the axis of said holder and said frustoconical surface portion adjoining web surfaces of said channel wall portions provides stop means for limiting radially inward travel of a cassette inserted into the space defined by said spaced opposed channels.
Claim 9
Dependent Claim
107 words
A recording tape cassette container comprising a base member; a cassette holder assembly; and means for mounting said cassette holder assembly on said base member for rotation about a horizontal axis; said cassette holder assembly including a cassette holder formed of resilient material and presenting opposed, aligned channel pairs for receiving a cassette in each of said channel pairs in generally spoke-like fashion about said horizontal axis, and recess means in the web surface portion of each of said aligned channels to receive a boss projecting from the end surface of a cassette received in such channel whereby the cassette is releaseably retained by said cassette holder.
Claim 10
Dependent Claim
107 words
A recording tape cassette container comprising a base member; a cassette holder assembly; and means for mounting said cassette holder assembly on said base member for rotation about a horizontal axis; said cassette holder assembly including a cassette holder formed of resilient material and presenting opposed, aligned channel pairs for receiving a cassette in each of said channel pairs in generally spoke-like fashion about said horizontal axis, and recess means in the web surface portion of each of said aligned channels to receive a boss projecting from the end surface of a cassette received in such channel whereby the cassette is releaseably retained by said cassette holder.
Claim 11
Dependent Claim
81 words
A recording tape cassette container as in claim 8 wherein said cassette holder assembly comprises a pair of like parts each having a generally radially extending wall portion having arcuately spaced channels formed therein and a central axially extending portion, means joining the ends of said central axially extending portions with the channels of one of said pair respectively aligned with the channels of the other of said pair to define a series of arcuately spaced cassette receiving and retaining spaces.
Claim 12
Dependent Claim
38 words
The recording tape cassette container of claim 9 further comprising a transparent cover member which cooperates with said base member to enclose said holder assembly while permitting visual observation of arcuately spaced cassettes retained by said holder assembly.
