It is equipped with an optical pick-up that reciprocates to reproduce or record records on disks, and furthermore, each disk mounting plate in the magazine rack is sequentially selected and swung at a predetermined angle to continuously record and reproduce data from a plurality of disks. In the above-mentioned magazine rack, the same number of rotating levers as the plurality of disk mounting plates are pivotally supported to detect the presence or absence of disks on each disk mounting plate from the presence or absence of rotational movement when the magazine rack is loaded into the housing. It is characterized by the fact that

[Effect]

According to this invention, the disk mounting plate in the magazine rack is continuously swung to the recording/reproducing position, and after reproduction, the next disk mounting plate repeats the same operation, making it possible to continuously record and reproduce. Further, since the rotary lever, which is a detection mechanism in the magazine rack, detects the presence or absence of a disk on the disk mounting plate, continuous recording and reproducing operations are facilitated.

〔Example〕

Hereinafter, a description will be given based on the embodiment shown in FIGS. 1 to 5, with the same reference numerals assigned to the same or equivalent parts as in the conventional art. In each figure, 16 is a magazine rack that is loaded onto the transfer table 2, and 17 is a disk mounting section that is pivotably mounted on a shaft 16b at a corner of the top plate 16a of the magazine rack.
The rotation of the drive mechanism is transmitted to each disk mounting plate through partial teeth 17a (area I in Figure 4) formed at the base of each plate, and the desired mounting plate is pointed one by one. It is designed to swing in the L direction. In addition, each mounting plate has a recess 1 as a mounting part.

A protrusion 18a is formed on the proximal end side of the disk holder attached to the disc holder, and a pin 19 hanging down from the protrusion 18a and a pin 2 erected on the rack bottom plate 16c.
When the magazine rack 16 is placed on the transfer table 2, the pin 19 slides on the slope of the trapezoidal protrusion 2a on the transfer table 2, and the disk holder 18 moves in the direction of arrow G with the spring 21. It swings against the spring force of the top plate 16a and retreats from the opening 16d for inserting the disk 2 and the notch 16e protruding from the top plate 16a, thereby facilitating the insertion of the disk 2. When the magazine rack 16 is removed from the transfer table 2, the disk holder 18 is returned to its original position by the force of the spring. Therefore, 22 is the notch 16
A rotary lever for detecting a disk is rotatably supported on a shaft 16f near e, corresponding to each disk mounting plate, and each protrusion 22a is a disk detection switch ( (not shown) and rotates around the shaft 16f in the direction of arrow S against the spring force of the spring 23. If there is a loading disk 3, the lever 22 The rotation of the disk 3 is regulated and the disk 3 is detected. 24 is magazine rack 16
It is arranged along the front surface and normally locks the disk mounting plate, and when one end portion 24a is pressed and biased, it slides in the direction of the arrow, and the hook portion 24b at the other end locks the disk mounting plate on each plate side of the disk mounting portion 17. This is a stopper that releases the recessed notch 17d formed on the edge so that each disk mounting plate can swing around the shaft 16b. Note that 16g is a recording section in which the recorded contents of the disk 3 are recorded.

Further, reference numeral 25 denotes an intermediate gear located between the gear 7 meshing with the loading motor 8 and the gear 6 meshing with the rack 5, which are meshed as gears 7 and 6 on both sides. The transfer table 2 is guided on the rails 26, 26 by. 27 meshes with the intermediate gear 25 on the back side of the rack 5 (on the left side in FIG. 3) and connects the loading motor 8.
This gear receives the rotational motion of the disk via the gear 7 and the intermediate gear 25, and rotates the gear 29 attached coaxially above the gear 28, thereby rotationally driving the disk mounting plate as shown by the imaginary line in FIG. pick up 9
It is made to be playable. Moreover, the gear 29 is moved up and down in the J direction by a lifting means (not shown). It should be noted that the partial gear 17a of the disk mounting plate is located only in the range I in the same figure, and is designed not to mesh with the gear 29 when it is raised or lowered. 30 is a cam that shares the shaft attached to the lower side of the intermediate gear 25, and a pin 3 that is installed outside the transfer table 2.

In other words, 38 is a lifting base mounted on rollers 37 located at four points of a rectangle, and 39 is a reproduction base tilted and supported by a cut-and-raised part 38a of the lifting base 38 via a pin 42. It is equipped with a playback mechanism such as Pickup 9. When the disk mounting plate is positioned in the playback mechanism as shown in FIG. 4, together with a lever 40 extending from the center of the end side of the device in the lifting base 38, the lever 40 cooperates when holding and playing the disk 3. The reproduction base 39 is configured. Note that 41 is a base on which the entire mechanism is placed.

When the stopper 24 of the magazine rack 16 is slid to open the disk mounting plate 17 and six disks 3 are mounted, and then loaded onto the transfer table 2, the disk presser 18 is retracted from the opening 16d. Insertion of the disk 3 becomes easier. Next, the loading motor 8 is driven to guide the transfer table 2 through the rack 5 into the player along the rails 26, 26, and to a predetermined position, that is, the magazine rack 1.
