DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to an apparatus capable of recording and reproducing of data in a recording medium disk. More particularly, it relates to a recording medium disk continuous-driving apparatus for continuously recording and reproducing a plurality of recording medium disks.
TECHNICAL BACKGROUND
Heretofore, as a recording medium disk, an audio compact disk has been known, for example. To record data in such compact disk or to reproduce the data from the disk, there has been proposed an apparatus such that a plurality of disks are arranged in an overlapping state with their surfaces to be recorded opposed and a disk among the disks is taken out by an arm-like carrier to transfer it in a desired position for reproduction as shown in Japanese Patent Application No. 78304/1981 (Japanese Unexamined Patent Publication No. 195363/1982). The conventional recording and reproducing apparatus of this kind has a problem that it is necessary to set each disk in the apparatus at every time of recording and reproducing, hence it takes much time of replacement of the disks when a plurality of disks are continuously driven.
DISCLOSURE OF THE INVENTION
In the present invention, there is provided a recording medium disk continuous-driving apparatus for recording data in a recording medium disk to be rotated and reproducing the data from the disk, which comprises 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 the recording medium disks and at least one opening formed between the loading sections so that a disk can be passed through the same, each of the loading sections being provided with a cut portion; a rotary drive unit which rotates the rotating bodies at predetermined angles independent of each other to bring the cut portion of the loading section of any one of the rotating bodies into an overlapping position to the openings of the other rotating bodies; and an elevating unit for raising and lowering any of the recording medium disks mounted on the loading sections in the overlapping positions by means of a lifter passing through the cut portions, whereby a plurality of recording medium disks can be continuously recorded and reproduced.
BRIEF DESCRIPTION OF THE INVENTION
FIGS. 1 to 10 show embodiments of the present invention in which FIG. 1 is a perspective view showing an important part of an embodiment;
FIG. 2 is a cross-sectional view of FIG. 1;
FIG. 3 is a diagram corresponding to FIG. 1 which shows a state that a compact disk is located in the apparatus as shown in FIG. 1;
FIG. 4 is a cross-sectional view of FIG. 3;
FIGS. 5 to 8 diagrams showing operations of the embodied apparatus;
FIG. 9 is a diagram showing the entirety of a compact disk player to which the apparatus of the present invention is applied; and
FIG. 10 is a cross-sectional view of an important part of another embodiment of the present invention.
BEST MODE FOR CARRYING OUT THE PRESENT INVENTION
In the following, the present invention will be described as to a reproducing apparatus (a disk player) using an audio compact disk. FIG. 1 shows an important part of a disk player in which a reference numeral (1) designates an upper table capable of receiving three compact disks (not shown), which is pivotted so as to be rotatable through a shaft 2. A lower table 3 having the same construction as the upper table is rotatably fitted to the shaft 2 at a position below the upper table 1. Reference numerals (4a), (4b), (4c) designate loading sections for the compact disks which are formed in the upper surface of the upper table (1), and each of the loading sections (4a), (4b), (4c) are so arranged that they are in a circle inscribed to the outer circumference of the table which is around the center of the upper table (1); they have a diameter slightly greater than that of the compact disk and have a recessed portion in the loading section in which the compact disk is fitted when the disk is mou
