DESCRIPTION:

BRIEF SUMMARY
FIELD OF THE INVENTION

The present invention relates to a recording disc reproducing device, wherein after a record case containing a recording medium (a record) in the shape of a disc is inserted to a predetermined position in the body of said device, said record is placed automatically on the turntable provided in said device by pulling out said record case, and when recovering said record an empty record case is inserted into the body of said device to thereby automatically recover said record case on the turntable.


BACKGROUND OF THE INVENTION

FIG. 1 through FIG. 3 show the structures of the disc case which can be used for the recording disc reproducing device according to the present invention, wherein a disc case 1 in the shape of a rectangle is composed of a disc case body 2 (hereinafter referred to as the case) and a cover 3 to be detachably combined with the opening 7 provided at the front side of the inserting direction X.sub.1 toward the device of the case 2. The case 2 and the cover 3 are formed for example from styrol resin.
The case 2 is formed by a pair of half bodies 4 which are molded by the same die and pasted together, the inside of which is provided with the disc holding space 5 (whose height is a little greater than the thickness of the disc 6) which is flat over its entire width and length, and the disc 6 (a recording medium) is held in this space 5. This space 5 has the opening 7 on the side of the inserting direction X.sub.1 and the sides of the remaining three directions are blocked.
Further, the same components of the case 2 are so disposed as to be positioned at right and left sides with respect to the centerline l as the center in the inserting direction.
Each half body 4 consists of a plate 8 having recessions 17 on the right and left sides (which serve to cause a hinge action as will be described below) and the ribs 9, 10, 11 provided along the three edges of this plate. With respect to the lower half body 4 shown in FIG. 1, the windows 12, with which the later described opening arms engage, are formed at right and left sides in the neighborhood on the side of the opening 7 and the holes 13, with which the later described bosses of the cover engage, are formed at the central portion in the neighborhood of the opening 7. A pair of tapers 14 are formed symmetrically on the edges of the opening 7. Such tapers are for guiding the insertion of the arms of the later described latching mechanisms. At the inner portion the stoppers 15, to which the disc 6 butts, are formed at the positions deviated toward right and left from the centerline l.
Furthermore, on the inside in the neighborhood of the opening of the ribs 9, 10, recessions 16 are provided with which the later described bosses of the cover 3 engage. The half bodies 4, thus formed, are bonded together with an adhesive which is wholly or partially applied to the periphery of the ribs 9, 10, 11.
At the end of the cover 3, a flange 18 is provided to close the opening 7 of the case 2 when the cover 3 is engaged and secured with the case 2. The cover includes notches 19 into which the later described opening arms can enter, slopes 27 which guide the later described disc holding arm in the reproducing device, and guide grooves 20 having thin portions 28 which are thinner than the glue guard of the disc 6 and are formed symmetrically to the centerline l on both faces. Bosses 21 are formed on the centerline l of both faces which engage with the holes 13 of said case 2. Furthermore, slopes 22 and tapers 23 are provided to guide the cover 3 as it enters the case 2. Protuberances 24 are provided which engage with said recessions 16 to thereby fix the cover 3 to the case 2. Arms 25, having the flexibility of resin, are provided at their ends with slopes 26 which engage with the releasing members of the cover 3.
FIG. 2 shows the conditions of the disc 6 and cover 3 as assembled into the case 2. Such conditions are illustrated with respect to FIG. 1, wherein the disc 6 butts against the stoppers 15 to be secured in the direction of depth
