Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 273 words
A multidisk containing player comprising playing means including a turntable, a pickup, and a disk clamp mechanism, said playing means being provided within a player housing, a magazine accommodating a plurality of disks and being removably mounted on a mounting portion as installed within said player housing, and a transfer mechanism for transferring said playing means toward a disk to be played and loading said playing means to said disk to be played, wherein said magazine comprises: a housing including an upper half portion and a lower half portion, both portions being separable from each other; and a plurality of plate-like trays having main surfaces and being arrayed within said housing and ejectable from and retractable into said housing along the main surfaces of said trays, said trays respectively carrying data recording disks on the main surfaces, and said transfer mechanism comprises: separating/positioning means for separating the upper and lower half portions, selecting a tray carrying a desired disk from among said trays, holding the selected tray, and separating the selected tray from the remaining trays in a tray separation direction orthogonal to the main surface of said tray to position said selected tray; movable carrying means for carrying said playing means; a support shaft supporting said movable carrying means, said movable carrying means being swingable about an axis between an insertion position, which allows said movable carrying means to be inserted between said trays, and a noninsertion position in a direction orthogonal to said tray separation direction, and said movable carrying means being movable along the axis of said support shaft; and drive means for swinging and moving said movable carrying means.
Claim 2
Dependent Claim 273 words
A multidisk containing player comprising playing means including a turntable, a pickup, and a disk clamp mechanism, said playing means being provided within a player housing, a magazine accommodating a plurality of disks and being removably mounted on a mounting portion as installed within said player housing, and a transfer mechanism for transferring said playing means toward a disk to be played and loading said playing means to said disk to be played, wherein said magazine comprises: a housing including an upper half portion and a lower half portion, both portions being separable from each other; and a plurality of plate-like trays having main surfaces and being arrayed within said housing and ejectable from and retractable into said housing along the main surfaces of said trays, said trays respectively carrying data recording disks on the main surfaces, and said transfer mechanism comprises: separating/positioning means for separating the upper and lower half portions, selecting a tray carrying a desired disk from among said trays, holding the selected tray, and separating the selected tray from the remaining trays in a tray separation direction orthogonal to the main surface of said tray to position said selected tray; movable carrying means for carrying said playing means; a support shaft supporting said movable carrying means, said movable carrying means being swingable about an axis between an insertion position, which allows said movable carrying means to be inserted between said trays, and a noninsertion position in a direction orthogonal to said tray separation direction, and said movable carrying means being movable along the axis of said support shaft; and drive means for swinging and moving said movable carrying means.
