Abstract
Abstract A multi-disk player according to the invention has a disk table (3) which comprises a large size disk mounting section (A) on which a large size disk is mounted, a turn table (4) rotatable about an axis (X₂) which is a predetermined eccentric distance ( X₁,X₂ ) away from the axis of the large size disk mounting section (A). The turn table includes thereon a plurality of small size disk mounting sections (B,C,D) on each of which a small size disk is placed. The eccentric distance is determined such that the axis of each small size disk mounting section is made to coincide with the axis of the large size disk mounting section by rotating the turn table (4). The player having such an arrangement has a disk driving device (6) whose circuit structure is simplified, and solely plays a plurality of types of disks having different diameters such as CDs and LDs. Further the player plays a disk arbitrarily selected from a plurality of small size disks and successively plays a plurality of small size disks.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
116 words
A multi-disk player having a disk table (3) which comprises a large size disk mounting section (A) on which a large size disk is mounted, a turn table (4) rotatable about an axis (X₂) which is a predetermined eccentric distance ( X₁,X₂ ) away from the axis (X₁) of the large size disk mounting section, wherein said turn table includes thereon a plurality of small size disk mounting sections (B,C,D) on each of which a small size disk is placed and said eccentric distance is determined such that the axis of each small size disk mounting section is made to coincide with the axis of the large size disk mounting section by rotating the turn table.
Claim 2
Dependent Claim
116 words
A multi-disk player having a disk table (3) which comprises a large size disk mounting section (A) on which a large size disk is mounted, a turn table (4) rotatable about an axis (X₂) which is a predetermined eccentric distance ( X₁,X₂ ) away from the axis (X₁) of the large size disk mounting section, wherein said turn table includes thereon a plurality of small size disk mounting sections (B,C,D) on each of which a small size disk is placed and said eccentric distance is determined such that the axis of each small size disk mounting section is made to coincide with the axis of the large size disk mounting section by rotating the turn table.

Claim 4
Dependent Claim
21 words
A multi-disk player according to claim 2, wherein said large size disk mounting section accommodates a 20cm LD and 30cm LD.
Claim 5
Dependent Claim
31 words
A multi-disk player according to any one of claims 1 to 3, wherein said small disk mounting sections respectively accommodate a plurality of types of small size disks having different diameters.
Claim 6
Dependent Claim
24 words
A multi-disk player according to claim 4, wherein said small size disk mounting sections respectively accommodate a 12cm CD, 12cm CD-V and 8cm CD-SINGLE.
Claim 7
Dependent Claim
23 words
A multi-disk player according to claim 4, wherein said turn table is used for a plurality of types of disks to be played.
Claim 8
Dependent Claim
24 words
A multi-disk player according to claim 1, which further comprises an optical pick-up for solely reading data from a plurality of types of disks.
Claim 9
Dependent Claim
23 words
A multi-disk player according to claim 1, further comprising a box-type frame in and from which said disk table is installed and removed.
Claim 10
Dependent Claim
61 words
A multi-disk player according to claim 1, wherein said large size disk mounting section includes a plurality of recessed areas for securely accommodating a plurality of types of disks having different diameters, said areas being concentrically formed in such a way that a corresponding disk fits to each area when the disk is placed on the large size disk mounting section.
Claim 11
Dependent Claim
61 words
A multi-disk player according to claim 1, wherein said small disk mounting section each include a plurality of recessed areas for securely accommodating a plurality of types of disks having different diameters, said areas being concentrically formed in such a way that a corresponding disk fits to each area when the disk is placed on the small size disk mounting section.
Claim 12
Dependent Claim
33 words
A multi-disk player according to claim 7, further comprising a disk driving section for rotating a disk and a guiding shaft for guiding the optical pick-up in a radial direction of the disk.
Claim 13
Dependent Claim
45 words
A multi-disk player according to claim 11, wherein said large disk mounting section comprises an opening which allows the relative upward/downward movement of the disk driving section and the movement of the optical pick-up along the guide shaft in a radial direction of the disk.
Claim 14
Dependent Claim
55 words
A multi-disk player according to claim 12, wherein each of said small size mounting sections comprises an opening which is overlapped with the opening of the large size disk mounting section when the small size mounting section is selected for use, so as to permit the movement of the optical pick-up along the guiding shaft.
Claim 15
Dependent Claim
77 words
A multi-disk player according to claim 1, wherein said turn table takes the form of a circle from which a D-shaped portion is cut away, when seeing from above, so that a cut end becomes flush with a forward end of the disk table and the turn table does not project but is fittingly installed within the disk table when the turn table is rotated to a predetermined position with the cut end in a reference position.
Claim 16
Dependent Claim
50 words
A multi-disk player according to claim 14, further comprising turn table resetting means by which the cut end is reset in the reference position automatically or upon receipt of an instruction issued by the user, when the cut end is not flush with the forward end of the disk table.
