Patent ID: 7571449

Claim:
A disk changer device comprising a magazine and a processing mechanism, said magazine comprising a plurality of disk holding members, said processing mechanism comprising a drafting unit, an elevating unit and an optical pick-up unit, said elevating unit being loaded with said drafting unit and said optical pick-up unit, said elevating unit being used to vertically move said drafting unit and said optical pick-up unit to a predetermined position corresponding to a predetermined disk holding member of the plurality of disk holding members, said disk changer device comprising: two wheels respectively installed on a top terminal and a bottom terminal on an edge of a disk insertion opening of said magazine; and a barrier belt loop for selectively traversing one of said plurality of disk holding members, said barrier belt loop being slidably engaged to said two wheels, wherein an inner section of said barrier belt loop comprises a traversing recess to be formed therein, said inner section being adjacent to said disk insertion opening of said magazine, mechanical coupling between said barrier belt loop and said processing mechanism enables said traversing recess constantly aligned with said optical pick-up unit, said traversing recess moving upwardly/downwardly following said processing mechanism wherein said processing mechanism vertically moves to a position that enabling said optical pick-up unit and said predetermined disk holding member to be horizontally coplanar, then said traversing recess being horizontally aligned with said predetermined disk holding member, thereby enabling said drafting unit to extract said predetermined disk holding member through said traversing recess into said optical pick-up unit.
