Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a drive device for a disk such as a compact disk, a video disk, an optical disk, etc.

[Background of the idea]

6 and 7 show a conventional disk drive device, FIG. 6 is a sectional view showing a large disk with an outer diameter of about 200 mm mounted on a tray in an operating state, and FIG. 7 is a perspective view of the tray. It is.

In FIG. 6, 1 is a tray, and 2 is a cylindrical storage portion of the tray 1 that can store a disk 3, and has a tapered portion that becomes smaller in diameter toward the bottom. Reference numeral 4 denotes a movable plate that can move up and down between the chassis 5 and the bottom surface of the storage section 2; 6 a disk receiver having three cylinders fixed to the upper surface of the movable plate 4; the disk receiver 6; When the moving plate 4 is set in the upper position, it projects upward from a hole 7 in the bottom surface of the storage section 2 of the tray 1. Reference numeral 8 designates a motor shaft rotatably supported by the chassis 5, and reference numeral 9 designates a slider at the tip of the motor shaft 8, which forms a tapered portion toward the front. Reference numeral 10 is a table formed integrally with the slider 9 on which the disk 3 is placed, and is positioned slightly above the bottom surface of the tray 1 and rotates with the rotation of the motor shaft 8.
In FIG. 7, reference numeral 11 indicates a guide hole through which a head (not shown) moves.

Next, to operatively mount the disk 3 in the storage section 2 of the tray 1, the disk 3 is placed on the disk receiver 6 using the inner edge of the storage section 2 of the tray 1 as a guide. Next, the moving plate 4 is lowered as shown in FIG. 6, and the hole 3a of the disk 3 is fitted into the tapered portion of the slider 9. Next, the disk 3 is pressed downward with a pressure bonding wheel (not shown), and the disk 3 is moved onto the table 10 using the tapered portion of the slider 9 as a guide.
Place it on top. The disk 3 is thus held between the pressure wheel and the table 10, and is driven to rotate by the rotational force applied to the table 10 via the motor shaft 8.

Nowadays, small disks with an outer diameter of about 120 mm, for example, have come out, and there is a desire to rotate these small disks by using the tray 1 for the conventional large disk 3.

However, in the conventional tray 1 shown in FIGS. 6 and 7, for example, a disk 3 smaller than the disk 3 shown in FIG.
When trying to insert the small disk, the dimension between the outer edge of the small disk 3 and the inner edge of the storage portion 2 of the tray 1 is too large, so there is a problem that positioning the small disk is troublesome.

[Purpose of invention]

The present invention is intended to solve the above-mentioned conventional problems, and an object of the present invention is to provide a disk drive device that can easily position a small disk as well as a large disk.

[Summary of the idea]

In order to achieve the above-mentioned conventional object, the present invention provides a disk drive device comprising a tray having a storage section for storing disks, and a disk receiver provided so as to be able to protrude into the storage section of the tray. It consists of a first disk holder for a large disk and a second disk holder for a small disk arranged inside the first disk holder, and the first disk holder also serves as a positioning means for the small disk. This feature allows for easy positioning of large and small disks in the tray storage section.

[Detailed explanation of the idea]

1 to 5 show embodiments of the present invention.
The figure is a sectional view showing the state before inserting a large disk into the tray storage area, Figure 2 is a sectional view showing the state after insertion, and Figure 3 is the state before inserting a small disk into the tray storage area. FIG. 4 is a cross-sectional view showing the state after insertion, and FIG. 5 is a perspective view of the tray.

In FIG. 1, 12 is a tray, and 13 is a cylindrical storage portion of the tray 12 that can accommodate a large disk 14, and has a tapered portion that becomes smaller in diameter toward the bottom. 15 is a movable plate that can be moved up and down between the chassis 16 and the bottom of the storage section 13; A is a composite disk holder fixed to the top surface of the movable plate 15; the disk holder A is composed of an arcuate projection. A disk receiver 18 for the large disk 14, and a disk for the small disk 19, which is comprised of a cylindrical protrusion located inwardly of the disk receiver 18 and whose height dimension is lower than that of the disk receiver 18 by X. Receiver 2
0, and the composite disk receiver A is a movable plate 1.
5 is set upward as shown in FIG.
The disk receivers 18 and 20 project upward from holes 21 and 22 in the bottom of the storage section 13 of the tray 12. 23 is a motor shaft rotatably supported by the chassis 16; 25 is a motor shaft 2;
The slider at the tip of No. 3 forms a tapered portion toward the front. 26 is a table on which the large and small disks 14 and 19 integrally formed with the slider 25 are placed; in FIG. 5, 27 is a guide hole through which the head (not shown) moves; , 19 is a hole formed in the center.

Next, a case in which the large disk 14 is mounted in the storage section 13 of the tray 12 in an operational state will be described.

First, as shown in FIG. 1, the large disk 14 is placed on the disk receiver 18 of the composite disk receiver A using the inner edge of the tray 12 as a guide. Next, the moving plate 15 is lowered as shown in FIG. 2, and the hole 28 of the large disk 14 is fitted into the tapered portion of the slider 25. Next, the large disk 14 is pressed downward by a pressure wheel (not shown). Then, the large disk 14 is guided by the tapered portion of the slider 25 and placed on the table 26. Therefore, the large disk 14 is held between the compression wheel and the table 26, and is driven to rotate by the rotational force applied to the table 26 via the motor shaft 23, thereby performing recording or reproduction.

Next, the case where the small disk 19 is mounted in the storage section 13 of the tray 12 in an operational state will be explained.
First, as shown in FIG. 3, the small disk 19 is placed on the disk receiver 20 using the inner edge of the disk receiver 18 of the large disk 14 as a guide. Next, the moving plate 15 is lowered as shown in FIG. 4, and the hole 29 of the small disk 19 is fitted into the tapered portion of the slider 25. Next, the small disk 19 is pressed downward using a crimping wheel (not shown). Then, the small disk 19 moves onto the slider 25 as shown in FIG.
is placed on the table 26 while being guided by the tapered portion of the table 26. Therefore, the small disk 19 is held between the compression wheel and the table 26, and is driven to rotate by the rotational force applied to the table 26 via the motor shaft 23, thereby performing recording or reproduction.

The disk drive device of the present invention has the above-described structure, and the large disk 14 is moved into the storage section 1 of the tray 12.
3, the position is determined by the inner edge of the tray 12, and when the small disk 19 is installed in the storage section 13 of the tray 12, the large disk 14 is positioned.
The positioning of both the large disk 14 and the small disk 19 is facilitated by the inner edge of the disk receiver 18, thereby improving the efficiency of recording and reproducing operations.

[Effect of idea]

According to the present invention, in a disk drive device comprising a tray having a storage section for storing a disk, and a disk receiver provided protrusively into the storage section of the tray, the disk receiver is provided with a first one for a large disk. It consists of a disk holder and a second disk holder for a small disk located inside the first disk holder, the large disk being positioned by the inner edge of the tray, and the small disk being positioned by the first disk holder for the large disk. Since the positioning is performed by the disk holder, it is easy to position both large and small disks, which has the effect of improving the efficiency of recording and reproducing operations.
