Abstract

Abstract A data storage case having a write/protect assembly includes a main body of the cartridge, a plurality of detection holes formed in the lateral side and on two flat sides of the main body of the cartridge adjacent a corner of the front side of the main body of the cartridge relative to the direction of insertion of the main body of the cartridge into the interior of the recording/reproducing apparatus, and mating detection elements inserted into these detection holes. The main body of the cartridge accommodates a disk-shaped recording medium, on which information signals can be recorded, and has apertures through which the signal recording section of the disk-shaped recording medium is exposed to outside. The mating detection elements may be moved between a first position and a second position within the detection holes.

Claim 3
Dependent Claim 94 words
A data storage case having a write/protect assembly according to claim 1 wherein a first of said mating detection elements engages said detection hole formed in said lateral side of said main body for facing outward relative to said interior and second and third ones of said mating detection elements engage a respective second and third one of said mating detection holes formed in said two major flat sides of said main body for facing outwards relative to said interior, said first and second mating detection elements being at right angles with each other.
Claim 4
Dependent Claim 105 words
A data storage case having a write/protect assembly according to claim 1 wherein one of said plurality of mating detection elements comprises a first mating detection element engaging in said detection hole formed in said lateral side of said main body for facing outwards relative to said interior and others of said plurality of mating elements comprise a second and third mating detection element engaged respectively in said detection holes formed in said two major flat sides of said main body for facing outwards relative to said interior, said first mating detection element being at right angles with said second and third mating detecting elements.
Claim 5
Dependent Claim 205 words
A data storage case having a write/protect assembly comprising a main body having two major surfaces and lateral surfaces for accommodating in an interior thereof a recording medium on which information signals can at least be recorded, a plurality of detection holes formed in at least one lateral surface and at least one major surface of said main body, and a write/protect member movably arranged in said main body, said write/protect member including a plurality of mating detection elements, said mating detection elements being movable together between first and second positions within respective ones of said plurality of detection holes, and wherein said write/protect member is located within a recess formed in said interior of said main body and wherein a slide guide formed on said write/protect member is pressed against a rear wall of said recess relative to a direction of insertion of the data storage case in to a recording and/or reproducing apparatus, and said slide guide is arranged on a side of said write/protect member opposite to the side provided with said mating detection elements and includes spaced-apart retention ribs, wherein corresponding mating retention ribs are provided in said recess for being selectively engaged by said retention ribs on said slide guide.
Claim 6
Dependent Claim 205 words
A data storage case having a write/protect assembly comprising a main body having two major surfaces and lateral surfaces for accommodating in an interior thereof a recording medium on which information signals can at least be recorded, a plurality of detection holes formed in at least one lateral surface and at least one major surface of said main body, and a write/protect member movably arranged in said main body, said write/protect member including a plurality of mating detection elements, said mating detection elements being movable together between first and second positions within respective ones of said plurality of detection holes, and wherein said write/protect member is located within a recess formed in said interior of said main body and wherein a slide guide formed on said write/protect member is pressed against a rear wall of said recess relative to a direction of insertion of the data storage case in to a recording and/or reproducing apparatus, and said slide guide is arranged on a side of said write/protect member opposite to the side provided with said mating detection elements and includes spaced-apart retention ribs, wherein corresponding mating retention ribs are provided in said recess for being selectively engaged by said retention ribs on said slide guide.
