Abstract
Abstract A disc cartridge having a cartridge main body and a shutter member is disclosed. The cartridge main body contains a disc-shaped recording medium and includes an aperture formed in one of a pair of planar portions for exposing at least an information recording area of the disc-shaped recording medium to outside. The shutter member opens or closes the aperture and is movably mounted on the cartridge main body. A braille representing portion for indicating the type of the disc-shaped recording medium is formed on a shutter member of the disc cartridge, a container casing containing the disc cartridge or an index sheet arranged between the disc cartridge and the packaging film sheet and acting as a sheath on which the braille representing portion is formed.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
170 words
A device for representing braille points on an information recording medium comprising: a cartridge main body, in the form of a rectangular casing for containing the information recording medium, having a pair of rectangular-shaped planar portions and plural lateral side sections provided along sides of said planar portions interconnecting said planar portions; sheathing means including a sheet having a free perimeter and which sheathes an outer surface of said cartridge main body, and a braille point representing means provided on said sheathing means at a position thereof readily touched by the hand or finger which indicates the type of the information recording medium contained in the cartridge main body, wherein said sheathing means comprises a lateral connecting web portion between first and second planar portions of said sheathing means which faces at least one of the lateral side sections of the cartridge main body; and wherein said braille point representing means is provided on said lateral connecting web portion which is narrower than said planar portions of the sheathing means.
Claim 2
Independent Claim
170 words
A device for representing braille points on an information recording medium comprising: a cartridge main body, in the form of a rectangular casing for containing the information recording medium, having a pair of rectangular-shaped planar portions and plural lateral side sections provided along sides of said planar portions interconnecting said planar portions; sheathing means including a sheet having a free perimeter and which sheathes an outer surface of said cartridge main body, and a braille point representing means provided on said sheathing means at a position thereof readily touched by the hand or finger which indicates the type of the information recording medium contained in the cartridge main body, wherein said sheathing means comprises a lateral connecting web portion between first and second planar portions of said sheathing means which faces at least one of the lateral side sections of the cartridge main body; and wherein said braille point representing means is provided on said lateral connecting web portion which is narrower than said planar portions of the sheathing means.
Claim 3
Dependent Claim
66 words
A device for representing braille points as claimed in claim 1, further comprising: a packaging film sheet wrapped around the sheathing means and the cartridge main body; wherein said film sheet is a thermally contractible thin sheet of synthetic resin which allows tactile identification of the braille point representing means provided on said sheathing means even when the sheathing means is wrapped with said film sheet.
Claim 4
Dependent Claim
42 words
A device for representing braille points as in claim 1, further comprising: first and second weakened portions formed at interconnecting regions between said first planar portion and the connecting web portion and said second planar portion and the connecting web portion, respectively.
Claim 5
Dependent Claim
66 words
A device for representing braille points as claimed in claim 3, further comprising: second and third weakened portions extending within the connecting web portion at right angles to both of the first and second weakened portions for enabling the braille point information representing portion to be removed as a separated portion for being affixed to one of the rectangular-shaped planar portions of the cartridge main body.
Claim 6
Dependent Claim
21 words
A device for representing braille points as claimed in claim 3 or 4, wherein said weakened portions are formed by perforations.
Claim 7
Dependent Claim
186 words
In combination, a printed sheet having a free perimeter and a cartridge main body containing an information signal recording medium, comprising the comprising: a first planar portion having edges which cover at least a part of one of a pair of rectangular-shaped planar portions of the cartridge main body having said planar portions and plural lateral side sections provided along sides of said planar portions interconnecting said planar portions, a second planar portion having edges which cover at least a part of the other of said planar portions of the cartridge main body, a lateral connecting web portion connected between a first edge of said first planar portion and a first edge of said second planar portion which faces at least one of the lateral side sections of the cartridge main body, and a braille point information representing portion formed on said connecting web portion which indicates the type of the information signal recording medium contained in the cartridge main body, wherein the connecting web portion is narrower than either of the first and second planar portions of the printed sheet and interconnects those planar portions.
Claim 8
Dependent Claim
186 words
In combination, a printed sheet having a free perimeter and a cartridge main body containing an information signal recording medium, comprising the comprising: a first planar portion having edges which cover at least a part of one of a pair of rectangular-shaped planar portions of the cartridge main body having said planar portions and plural lateral side sections provided along sides of said planar portions interconnecting said planar portions, a second planar portion having edges which cover at least a part of the other of said planar portions of the cartridge main body, a lateral connecting web portion connected between a first edge of said first planar portion and a first edge of said second planar portion which faces at least one of the lateral side sections of the cartridge main body, and a braille point information representing portion formed on said connecting web portion which indicates the type of the information signal recording medium contained in the cartridge main body, wherein the connecting web portion is narrower than either of the first and second planar portions of the printed sheet and interconnects those planar portions.
Claim 9
Dependent Claim
40 words
The printed sheet as claimed in claim 6 further comprising: first and second weakened portions formed at interconnecting regions between said first planar portion and the connecting web portion and said second planar portion and the connecting web portion, respectively.
Claim 10
Dependent Claim
63 words
The printed sheet as claimed in claim 7, further comprising: second and third weakened portions extending within the connecting web portion at right angles to both of the first and second weakened portions for enabling the braille point information representing portion to be removed as a separated portion for being affixed to one of the rectangular-shaped planar portions of the cartridge main body.
Claim 11
Dependent Claim
18 words
The printed sheet as claimed in claim 7 or 8, wherein said weakened portions are formed by perforations.
