The disc player includes a driving device, a chassis and a cover. The driving device is for driving a disc. The chassis, which accommodates the driving device, has a bottom surface for supporting the disc player and a top surface opposite to the bottom surface. At least a portion of the driving device protrudes on the top surface. The cover, movably connecting to the chassis, is selectively in an open state or a closed state in relation to the chassis. When the cover is in the open state, it is capable of holding and accommodating the disc and separates the disc from the driving device. When the cover is in the closed state, it overlaps the top surface and engages the driving device with the disc. ## Claims ### Claim 1 A disc player for operating a disc, comprising: a driving device for driving said disc; a chassis for accommodating said driving device, the chassis having a bottom surface for placing said disc player on a supporting surface, and a top surface opposite to said bottom surface, at least a portion of said driving device protruding on said top surface;

and when said cover is in said closed state, said cover substantially overlaps said top surface and said driving device engages with said disc. ### Claim 2 (depends on 1) The disc player of claim 1, wherein said cover further comprises: a protrusion, wherein when said cover moves to said open state, said protrusion supports said disc; and when said cover is in said closed state, said disc is not in contact with said protrusion. ### Claim 3 (depends on 1) The disc player of claim 1, wherein said cover further comprises: a clamper for fastening said disc, said clamper being located below said cover and having an annular flange, said annular flange having a first diameter, wherein when said cover is in said closed state, said clamper and said driving device respectively fasten said disc. ### Claim 4 (depends on 3) The disc player of claim 3, wherein said cover further comprises: a clamper holder being located below said cover and attached to said cover, said clamper holder having an annular protrusion for supporting said clamper, and said annular protrusion having an inner diameter smaller than said first diameter, wherein when said cover is in said open state, said clamper holder supports said clamper. ### Claim 5 (depends on 3) The disc player of claim 3, wherein a portion of said clamper corresponding to said driving device is made of a first material and a portion of said driving device corresponding to said clamper is made of a second material, and said first material and said second material attract each other. ### Claim 6 (depends on 3) The disc player of claim 3, wherein said annular flange is made of a third material and a portion of said cover corresponding to said annular flange is made of a fourth material, and said third material and said fourth material attract each other. ### Claim 7 (depends on 2) The disc player of claim 2, wherein a portion of said protrusion for supporting said disc comprises a lubricant material. ### Claim 8 (depends on 1) The disc player of claim 1, wherein said cover is either rotatably or vertically movably connected to said chassis. ### Claim 9 A disc player for operating a disc, comprising: a driving device for driving said disc; a chassis for accommodating said driving device, said chassis having a bottom surface for placing said disc player on a supporting surface, and a top surface opposite to said bottom surface, at least a portion of said driving device protruding on said top surface; and a cover movably connected to said chassis, the cover being selectively in an open state or in a closed state relative to said chassis, and comprising a positioning device for positioning said disc, wherein when said cover is in said open state, said cover accommodates said disc and said disc and said driving device are separated from each other; and when said cover is in said closed state, said cover substantially overlaps said top surface and said driving device engages with said disc. ### Claim 10 (depends on 9) The disc player of claim 9, wherein said cover further comprises: a protrusion; wherein when said cover is in said open state, said protrusion supports said disc; and when said cover is in said closed state, said disc is not in contact with said protrusion. ### Claim 11 (depends on 9) The disc player of claim 9, wherein said cover further comprises: a clamper for fastening said disc, said clamper being located below said cover and having an annular flange, said annular flange having a first diameter, wherein when said cover is in said closed state, said clamper and said driving device respectively fasten said disc. ### Claim 12 (depends on 11) The disc player of claim 11, wherein said cover further comprises: a clamper holder located below said cover and attached to said cover, said clamper holder having an annular protrusion for supporting said clamper, and said annular protrusion having an inner diameter smaller than said first diameter, wherein when said cover is in said closed state, said clamper holder supports said clamper. ### Claim 13 (depends on 11) The disc player of claim 11, wherein a portion of said clamper corresponding to said driving device is made of a first material and a portion of said driving device corresponding to said clamper is made of a second material, and said first material and said second material attract each other. ### Claim 14 (depends on 11) The disc player of claim 11, wherein said annular flange is made of a third material and a portion of said cover corresponding to said annular flange is made of a fourth material, and said third material and said fourth material attract each other. ### Claim 15 (depends on 10) The disc player of claim 10, wherein a portion of said protrusion for supporting said disc is made of a lubricant material. ### Claim 16 (depends on 9) The disc player of claim 9, wherein said cover is either rotatably or vertically movably connected to said chassis. ### Claim 17 A disc player for operating a disc, comprising: a driving device for driving said disc; a chassis for accommodating said driving device, said chassis having a bottom surface for placing said disc player and a top surface opposite to said bottom surface, at least a portion of said driving device protruding on said top surface; and a cover movably connected to said chassis, the cover being selectively in an open state or a closed state relative to said chassis, said cover including: a protrusion; a clamper for fastening said disc, said clamper being located below said cover and having an annular flange, said annular flange having a first diameter; and a clamper holder located below said cover and attached to said cover, said clamper holder having an annular protrusion for supporting said clamper, and said annular protrusion having an inner diameter smaller than said first diameter, wherein when said cover is in said open state, said protrusion supports said disc and said clamper holder supports said clamper, and said disc and said driving device are separated from each other; and when said cover is in said closed state, said cover substantially overlaps said top surface, said disc is not in contact with said protrusion, and said clamper and said driving device respectively clamp said disc. ### Claim 18 (depends on 17) The disc player of claim 17, wherein a portion of said clamper corresponding to said driving device is made of a first material and a portion of said driving device corresponding to said clamper is made of a second material, and said first material and said second material attract each other. ### Claim 19 (depends on 17) The disc player of claim 17, wherein said annular flange is made of a third material and a portion of said cover corresponding to said annular flange is made of a fourth material, and said third material and said fourth material attract each other.
