Abstract
Abstract A cassette device contains information bearing articles and includes two substantially flat cover portions mounted to pivot with respect to each other about an axis of rotation. A means projects outwardly from each cover portion toward the other cover portion and each said projecting means is interconnected with respect to each other at the axis of rotation thereby providing a pivot joint for the cover portion. Edge protecting means extend substantially perpendicularly from each cover portion. Each of the edge protecting means is disposed along a complementary peripheral section of each cover portion so that the device is substantially enclosed around the information bearing articles when the cover portions are registered with respect to each other.

Total Claims: 11
Claim 1
Independent Claim
242 words
A cassette device for containing information bearing articles, said device comprising: a. two substantially flat cover portions mounted to pivot with respect to each other about an axis of rotation that is normal to said cover portions and the information bearing articles being disposed between the cover portions, b. means projecting outwardly from each cover portion toward the other cover portion, c. each said projecting means being eccentrically located on the cover portions and interconnected with respect to each other and said information bearing articles at said axis of rotation thereby providing a pivot joint for the cover portions, d. edge protecting means extending substantially perpendicularly from each cover portion toward the other cover portion to protect the edges of the information bearing articles, e. each said edge protecting means including a first wall section extending along a first peripheral section of one cover portion and a second wall section extending along a second peripheral section of the other cover portion, f. said first peripheral wall section being in complementary relationship with respect to said second peripheral wall section to substantially enclose the information bearing articles when the cover portions are registered with respect to each other, g. said peripheral wall sections being at different non-overlapping locations around the periphery of the device whereby the information bearing articles may be selectively pivoted about said pivot joint, h. said cover portions being rectangular and having the same size with respect to each other.
Claim 2
Dependent Claim
242 words
A cassette device for containing information bearing articles, said device comprising: a. two substantially flat cover portions mounted to pivot with respect to each other about an axis of rotation that is normal to said cover portions and the information bearing articles being disposed between the cover portions, b. means projecting outwardly from each cover portion toward the other cover portion, c. each said projecting means being eccentrically located on the cover portions and interconnected with respect to each other and said information bearing articles at said axis of rotation thereby providing a pivot joint for the cover portions, d. edge protecting means extending substantially perpendicularly from each cover portion toward the other cover portion to protect the edges of the information bearing articles, e. each said edge protecting means including a first wall section extending along a first peripheral section of one cover portion and a second wall section extending along a second peripheral section of the other cover portion, f. said first peripheral wall section being in complementary relationship with respect to said second peripheral wall section to substantially enclose the information bearing articles when the cover portions are registered with respect to each other, g. said peripheral wall sections being at different non-overlapping locations around the periphery of the device whereby the information bearing articles may be selectively pivoted about said pivot joint, h. said cover portions being rectangular and having the same size with respect to each other.
Claim 3
Dependent Claim
45 words
A device as defined in claim 1 wherein: the projecting means are placed eccentrically at the periphery of the cover portions so that the information bearing articles are exposed when the cover portions are rotated with respect to each other about the axis of rotation.
Claim 4
Dependent Claim
31 words
A device as defined in claim 2 wherein: each of the information bearing articles has a hole through which the projecting means extend to hold said articles between the cover portions.
Claim 5
Dependent Claim
33 words
A device as defined in claim 1 wherein: each projecting means comprises a sleeve member, each said sleeve member having a size and shape effective to fit together for forming the pivot joint.
Claim 6
Dependent Claim
27 words
A device as defined in claim 4 wherein: a quick coupling means is disposed at the pivot joint to provide a detachable connection between the cover portion.
Claim 7
Dependent Claim
44 words
A device as defined in claim 1 wherein: said projecting means being located at a corner of the cover portions and each said wall section extends along one short side and one long side of each cover portion thereby enclosing the information bearing articles.
Claim 8
Dependent Claim
46 words
A device as defined in claim 6 wherein: the information bearing articles are card members having substantially the same shape as the cover portions, the peripheral wall sections are adjacent the edges of the cards when the cover portions are registered with respect to each other.
Claim 9
Dependent Claim
28 words
A device as defined in claim 1 wherein: each of the projecting means is attached to a respective cover portion and detachably interconnected with respect to each other.
Claim 10
Dependent Claim
47 words
A device as defined in claim 8 wherein: the information bearing articles are card members having openings through which the projecting means are removably disposed, the peripheral wall sections are adjacent the edges of the cards when the cover portions are registered with respect to each other.
Claim 11
Dependent Claim
16 words
A device as defined in claim 1 wherein: the cover portions are composed of transparent material.
