Abstract

Abstract A disc case is constructed for receiving releasably a disc on which information data are recorded and for supporting the disc rotatably in the disc case, and can be set into a reproducing apparatus with the disc received in the disc case. The disc case comprises: a first case member having a disc receiving area on its central portion; a second case member associated with the first case member to be able to open and close the disc receiving area; and a locking means having first and second locking members, a first locking member being formed integrally on one of the first and second case members and a second locking member being formed integrally on the other of the first and second case members and locks the first and second case members in a closed state with the disc receiving area closed in cooperation with the first locking member. The second locking member has an opening button which elastically deforms the second locking member and release the locking of the first and second case members when operated. The second locking member further comprises a spacing member which space the first and second case member from each other in the direction to open when the oprating button is operated.

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 182 words
A disc case for receiving a disc on which information data are recorded and for supporting said disc rotatably in said disc case, said disc case being able to be set into a reproducing apparatus with said disc received in said disc case and receiving said disc releasably, wherein said disc case comprises: a first case member having a disc receiving area on its central portion; a second case member (an upper case) associated with said first case member to be able to open and close said disc receiving area; and locking means having two locking members, a first locking member of which is formed integrally on one of said first and second case members and a second locking member of which is formed integrally on the other of said first and second case members and locks said first and second case members in a closed state with said disc receiving area closed in cooperation with said first locking member, said second locking member having integrally an operating part which release the locking of said first and second case members when operated.
Claim 2
Dependent Claim 182 words
A disc case for receiving a disc on which information data are recorded and for supporting said disc rotatably in said disc case, said disc case being able to be set into a reproducing apparatus with said disc received in said disc case and receiving said disc releasably, wherein said disc case comprises: a first case member having a disc receiving area on its central portion; a second case member (an upper case) associated with said first case member to be able to open and close said disc receiving area; and locking means having two locking members, a first locking member of which is formed integrally on one of said first and second case members and a second locking member of which is formed integrally on the other of said first and second case members and locks said first and second case members in a closed state with said disc receiving area closed in cooperation with said first locking member, said second locking member having integrally an operating part which release the locking of said first and second case members when operated.
Claim 3
Dependent Claim 32 words
A disc case according to claim 1, wherein said operating part consists of an operating button, and wherein said second locking member comprises an elastic arm member connected to said operating button.
Claim 4
Dependent Claim 68 words
A disc case according to claim 2, wherein said elastic arm member consists of at least two arms arranged in line, and wherein the locking of said first and second case members is released by elastic deformations of said two arms in the direction of such line in accordance with the movement of said operating button which is produced by its operation in the direction of said line.
Claim 5
Dependent Claim 80 words
A disc case according to claim 2, wherein said disc case further comprises: a spacing member for spacing said first and second case member, which is arranged on one of said first and second case member on which said first locking member is arranged, and which spaces said first and second case member from each other in the direction to open in accordance with the elastic deformation of said arms which is produced by the operation of said operating button.
Claim 6
Dependent Claim 101 words
A disc case according to claim 1, wherein said first case member consists of: a frame with a recess, which forms said disc receiving area, on its central portion, and a magazine plate applied to a surface of said frame, said magazine plate being provided with an inserting aperture through which a turntable of the reproducing apparatus for driving to rotate said disc is introduced in a region of a position corresponding to said recess of said frame, and another inserting aperture through which a reproducing head of the reproducing apparatus accesses a portion of information data recorded on said disc.
Claim 7
Dependent Claim 16 words
A disc case according to claim 5, wherein said magazine plate is made of metal plate.
Claim 8
Dependent Claim 80 words
A disc case according to claim 5, wherein said frame of said first case member is made of plastics and provided with a plurality of bosses disposed on said frame for connecting said frame to said magazine plate; wherein said magazine plate is provided with a plurality of holes for engaging said bosses; and wherein said frame and said magazine plate are connected by press said bosses with heat in the state inserted into said holes of said magazine plate.
Claim 9
Dependent Claim 16 words
A disc case according to claim 7, wherein said magazine plate is made of metal plate.
Claim 10
Dependent Claim 46 words
A disc case according to claim 5, further comprising: a shutter plate, which is interposed and supported rotatably between said frame and said magazine plate of said first case member, for opening and closing said another inserting aperture provided on said magazine plate by its rotation.
Claim 11
Dependent Claim 49 words
A disc case according to claim 9, wherein an axis of rotation of said shutter plate is eccentric to the center of said shutter plate, and wherein an operating part for operating said shutter plate to open and close is formed in a region near said axis of rotation.
Claim 12
Dependent Claim 56 words
A disc case according to claim 10, wherein said shutter plate has a substantially elliptical inserting aperture through which the turntable for driving to rotate said disc is introduced, and another inserting aperture of slit form through which the reproducing head accesses a portion of information data recorded on said disc when said shutter plate opened.
Claim 13
Dependent Claim 87 words
A disc case according to claim 1, wherein, during set into the reproducing apparatus, while said disc case is fixed in position within the reproducing apparatus, said disc is driven in rotation, and wherein said disc case further comprises: at least a pair of holes, arranged on at least one surface of said disc case, for positioning said disc case by engaging projections arranged on the reproducing apparatus during set into the reproducing apparatus, one hole of said pair of holes being formed as a loose hole.
Claim 14
Dependent Claim 20 words
A disc case according to claim 12, wherein said holes is formed asymmetrically with the center of said disc case.
