Abstract
Abstract A continuous-driving apparatus is so constructed that a recording medium disks (30a) are mountable on loading sections (4a), (4c) through cut portions (6a), (6c) and openings (5), (9) formed at the outer circumferential parts of rotating bodies (1), (3) which have a common center of rotation and are arranged in a juxtaposition; and the rotating bodies (1), (3) are caused to relatively rotate so that the specified cut portions (6a), (6c) are brought into an overlapping position with respect to the openings (5), (9): and the recording medium disk (30a) is transferred to a predetermined position by means of an elevating unit (10).

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
168 words
A recording medium disk continuous-driving apparatus for recording data in a recording medium disk to be rotated and reproducing the data from said disk, characterized by comprising: a plurality of rotating bodies having a common center of rotation, each of which is provided at the outer circumferential part with a plurality of loading sections for receiving said recording medium disks and at least one opening formed between said loading sections so that a disk can be passed through the same, each of said loading sections being provided with a cut portion; a rotary drive unit which rotates said rotating bodies at predetermined angles independent of each other to bring said cut portion of the loading section of any one of said rotating bodies into an overlapping position to said openings of the other rotating bodies; and an elevating unit for raising and lowering any of said recording medium disks mounted on said loading sections in the overlapping positions by means of a lifter passing through said cut portions.
Claim 2
Dependent Claim
168 words

Claim 3
Dependent Claim
19 words
A recording medium disk continuous-driving apparatus according to claim 1, wherein said recording medium disk has optically recorded data.
