DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a thin disk drive, and more particularly, to a thin disk drive incorporated in a notebook personal computer or the like.

[0002]

2. Description of the Related Art Heretofore, as a thin disk device of this kind, a CD-ROM, -R, -RW, DVD-R, -RO
M and -RAM drive devices and FDD (floppy disk drive device) are known. The thin drive device is formed integrally with the housing or detachably mounted on the housing, and is formed so that each recording medium can be accommodated in the housing.

FIG. 6 is a perspective side view showing an example of a conventional thin disk device, and FIGS. 7 (a), 7 (b) and 7 (c) show FIG.
FIG. 4 is a perspective side view, a bottom view, and a top view showing a state where the tray of the thin disk device shown in FIG.

FIGS. 6 and 7 (a), (b) and (c)
Referring to FIG. 1, a conventional thin disk device 60 is a CD-R
This is an OM drive device, which is a device built in a housing of a notebook personal computer (not shown). The illustrated disk device 60 is a disk device with a built-in tray in which a disk drive / playback mechanism such as an optical pickup, a disk motor, and a turntable is mounted (mounted) on the tray 62. FIG. 6 shows a state in which the tray 62 has been moved to the disk mounting position stored in the main chassis (outer case) 61, and FIG.
2 shows a state in which the disk 2 has been moved to a disk replacement position pulled out of the main chassis (outer case) 61.

[0005] The disk device 60 is a disk (CD-R).
OM) (not shown).
The tray 62 is formed on one side of the tray 62.
Guide 63 formed continuously on the edge of the
And a tray sliding mechanism 64 for slidably supporting the tray.

The tray 62 is formed so that the width of the disk (not shown) is smaller than the outer shape of the disk so that a part of the disk protrudes from the tray 62. Further, the tray 62 is configured to be slidable in the front-rear direction with respect to the main chassis 61 as indicated by arrows A and B in the figure by manual operation by a tray sliding mechanism 64 including a guide 63. In FIG. 6, the tray 62 is inserted in the direction of arrow B and is located at the disk mounting position, and in FIG. ing.

As shown in FIG. 7 (a), the tray 62 has a disk facing surface 62a for forming a space for receiving the disk, and a pickup and turntable opening formed in the disk facing surface 62a. 62b. The disk facing surface 62a has a width smaller than the outer diameter of the disk, and is formed so as to cover an area of about ２ of the disk. As a result, the size of the disk device 60 can be reduced.

A front bezel (panel) 65 is fixed to the front end of the tray 62. Front tray 65 is tray 6
2 and slides in the front-rear direction indicated by arrows A and B. A switch button 66 is provided slightly to the right of the center of the front bezel 65 to release the lock by a lock mechanism described later when the tray 62 is pulled out. Therefore,
When the switch button 66 is turned on in the state shown in FIG. 6, the front bezel 65 is moved to the main chassis 6 as described later.
A predetermined amount protrudes in the direction A with respect to 1. This facilitates the operation of pulling out the tray 62.

At the rear (back) of the main chassis 61,
A circuit board 67 is provided, and a drive unit (not shown) is attached to the tray 62. As described above, since the tray 62 moves in the directions of the arrows A and B together with the drive unit, the connection between the drive unit and the circuit board 67 is performed using the flexible board 69. A circuit board side end of the flexible board 69 is connected to the circuit board 67.
Is connected to the connector 70 disposed in the connector. The drive unit side end of the flexible substrate 69 is connected to the motor base 7.
1 is connected to a connector (terminal section) 72 provided in the first section.

FIG. 8 is a partial view mainly showing a small substrate provided inside the switch button 66 or the like in FIGS. 6 and 7.
Is a side view, and (b) is a front view, showing a state in which the front bezel 65 is removed.

As shown in FIGS. 8A and 8B, the small substrate 50 is provided with a switch button 66 operated at the time of ejection.
Is provided with a switch contact 66a pressed by
An LED display lamp (not shown) for driving detection display is provided.

The small substrate 50 is fixed to a tray 62 by screws 51 or the like. Further, an adhesive is attached to the back surface of the small substrate 50 and fixed to the tray 62.

[0013]

However, in the above-described conventional small-substrate-incorporating structure, the small-substrate 50 and the like are fixed to the tray by screws. And it hindered space reduction.

In the method of attaching and fixing an adhesive to the back of a small substrate, the area of the small substrate can be reduced by the amount of no screw, but it takes time and effort for positioning and attaching.
There is also a problem in terms of mechanical strength such as adhesive strength.

Therefore, the technical problem of the present invention is that it does not require an adhesive or a screw, has excellent positioning and mechanical strength, is excellent in workability, and can be reduced in size and space because it can reduce the area and space. It is an object of the present invention to provide a built-in structure of a small substrate of a thin drive device which can be made smaller.

[0016]

According to the present invention, there is provided a thin disk device having a lower cover, a tray for moving a recording medium to a storage / discharge position, and an eject switch for enabling the tray to be pulled out of a locked state. In addition, a thin disk device in which the small substrate is fixed by mechanically sandwiching the lower cover and the tray is obtained.
