Description

[Detailed description of the invention] "Industrial application field" This invention is a turntable equipped with a disk that records music or images as digital signals,
The present invention relates to a disk loading device such as a disk player that records or reproduces information on a disk by pickup.

"Prior Art" Conventionally, there was a technology in which a leather disk with a diameter of 30 cm or a compact disk with a diameter of 8 cm was placed on a tray and moved into and out of the turntable position.

``Problems to be Solved by the Invention'' The above-mentioned conventional technology has a set of turntable and pick-up and moves the tray only in the direction of entry and exit, so the overall structure is simple and can be constructed at low cost. However, there were problems in handling operations, such as the need to selectively select disks and place them on the tray.

``Means for Solving the Problems'' However, the present invention provides a device for moving a tray on which a plurality of disks of different diameters are placed into and out of the case of the machine. 1 forming a disk mounting surface, while forming the first disk mounting surface.
A small diameter second plate is placed between the disk mounting surface and the tray insertion end.
The tray is characterized in that a disk mounting surface is formed so that two small diameter disks can be placed on the tray at the same time.

``Function'' Therefore, two small-diameter disks can be alternately and continuously mounted on the turntable without the need for loading and unloading trays or replacing disks, simplifying the tray structure, turntable structure, etc., and simplifying handling operations. It is possible to easily improve sexual performance.

"Embodiments" Hereinafter, embodiments of the present invention will be described in detail based on the drawings. FIG. 1 is an external plan view of the disc player, and FIGS. 2 and 3 are plan explanatory views of the inside of the disc player, in which a turntable 1 and a laser pickup 2 are disposed inside the machine case 3.
It is equipped with a tray 4 that can be taken in and out of the machine case 3, and has a large-diameter disk mounting surface 6 on which a large-diameter leather disk 5 with a diameter of 30 cm is placed, and a small-diameter first surface 6 on which a small-diameter compact disk 7, 8 with a diameter of 8 cm is placed. Second disk mounting surfaces 9 and 10 are formed on the upper surface of the tray 4.

Further, a first disk mounting surface 9 is provided on the same axis as the large diameter disk mounting surface 6, and a second disk mounting surface 1 is provided between the first disk mounting surface 9 and the insertion end of the tray 4.
0, and two small-diameter disks 7 and 8 are placed on the tray 4 at the same time via the respective mounting surfaces 9 and 10. 2 and 3, and the length of the tray 4 in the in/out direction is made shorter than the diameter length (8 cm) of the disks 7 and 8, which have a smaller diameter than the machine case 3.
As shown in the figure, with the tray 4 inserted into the machine case 3, move the tray 4 in the in/out direction,
The small diameter disks 7 and 8 on the first and second disk mounting surfaces 9 and 10 are alternately and continuously placed on the turntable 1.
It is configured such that the information on each disk 7, 8 can be read by the pickup 2.

Furthermore, FIG. 4 shows a modified example in which the second disk mounting surface 10 is formed to a size on which a compact disk 11 with a diameter of 12 cm can be placed, and
cm and 12 cm discs 7 and 11 on each mounting surface 9 and 1
It is also possible to simultaneously place the discs 7 and 11 on the turntable 1 via the discs 0 and move the tray 4 in the direction of entry and exit within the machine case 3, thereby alternately and successively mounting the discs 7 and 11 on the turntable 1.

"Effects of the Invention" As is clear from the above embodiments, the present invention provides a device for loading and unloading a tray 4 on which a plurality of disks 5, 7, 8, and 11 of different diameters are placed in and out of the case 3 of the machine. A first disk mounting surface 9 of a small diameter is formed on the same axis as the surface 6, while a second disk mounting surface 10 of a small diameter is formed between the first disk mounting surface 9 and the insertion end of the tray 4, and two disks are mounted. It is configured so that the small diameter disks 7, 8, and 11 of
To enable the small diameter disks 7, 8, and 11 to be alternately and continuously mounted on the turntable 1, and to simplify the structure of the tray 4 and the turntable 1, and to easily improve handling and operability. This has practical effects such as the ability to
