Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disk drive for rotating a disk, such as a compact disk (CD) or a digital video disk (DVD), mounted on the turntable, and more particularly to a turntable. The present invention relates to a disk drive device configured so that a disk mounted on the disk drive can be easily taken out.

[0002]

2. Description of the Related Art First, terms used in this specification are defined. The term "information recording disk" in this specification is a general term for disks represented by optical disks such as CDs and DVDs, magneto-optical disks, and the like. signal,
An information signal such as a data signal is transferred to the "information recording disc".
Recording information on an "information recording disk" or reproducing an information signal recorded on an "information recording disk" in advance, or recording an information signal on an "information recording disk" and reproducing the information signal; The “drive device” refers to a drive device that rotationally drives the “information recording disk”.

Next, a conventional disk drive will be described with reference to FIGS. 8 and 9. FIG. FIG. 8 is a conceptual diagram showing a cross section of an example of a conventional general disk drive device, and FIG. 9 is a conceptual diagram showing another example of a general disk drive device of the prior art.

First, a description will be given of a conventional disk drive device 1A shown in FIG. In the disk drive 1A, an information recording disk mounting recess 3 is usually formed in a part of a frame or cabinet (hereinafter, typically referred to as "cabinet") 2, and the information recording disk mounting recess 3 is provided with a turntable. 4 is provided and is driven to rotate at a predetermined rotation speed by a drive motor (not shown). An opening / closing lid 5 is pivotally supported on one end of the information recording disk mounting recess 3 around a shaft 6 so as to cover the information recording disk mounting recess 3.

Normally, the disk drive device 1A having such a configuration is mounted on an audio device such as a portable CD player and a CD radio cassette player, and an information device such as a CD-ROM player.
In this case, CD software in which information signals of data such as music and dictionaries are pre-recorded is mounted on the turntable 4, and the information recording disk mounting concave portion 3 is closed with the opening / closing lid 5, and thus mounted. When reading an information signal from the information recording disk D, the information recording disk D
, And is scanned by an optical pickup (not shown) to sequentially read out the information signal so that music and data can be viewed on headphones or a monitor.

When the information recording disk D mounted on the turntable 4 of the disk drive device 1A having the above-described configuration is to be taken out, the cover 5 is usually opened, and the user uses his / her own hand to obtain the information. The recording disk D is grasped and taken out. However, when the information recording disk D is taken out, it is difficult to take out the information recording disk D because the user's finger touches a part other than the information recording disk D because the information recording disk D is in the recessed information recording disk mounting recess 3.

This point is improved in another conventional disk drive device 1B shown in FIG. In the disc drive device 1B, the recess 7 is large enough to allow a finger to be inserted into the bottom surface of the information recording disk mounting recess 3 corresponding to the lower part of the periphery of the information recording disk D mounted on the turntable 4. To facilitate removal of the information recording disk D from the information recording disk mounting recess 3.

[0008]

However, in the above-mentioned disk drive device 1A, the information recording disk mounting recess 3 is provided.
There is a drawback in that the degree of freedom in design is limited, for example, a space for providing the recess 7 must be taken.

SUMMARY OF THE INVENTION The present invention has been made to solve these problems, and it is intended to remove an information recording disk from an information recording disk mounting recess of a disk drive device.
It is an object of the present invention to obtain a disk drive device from which the information recording disk can be easily taken out.

[0010]

Therefore, a disk drive device according to a first aspect of the present invention is provided with an information recording disk mounting recess formed in a cabinet and an information recording disk mounting recess provided in the information recording disk mounting recess. In a disk drive device comprising a turntable for mounting and rotating a disk and a drive motor for rotating the turntable, when the information recording disk mounted on the turntable is taken out, the turntable is rotated. Having a floating device for floating from the rotating surface during driving in the direction of the opening of the information recording disk mounting concave portion,
The above problem has been solved.

According to a second aspect of the present invention, there is provided a disk drive device comprising: a cabinet having an information recording disk mounting recess formed therein; and an information recording disk mounted on the information recording disk mounting recess. It comprises a rotating turntable, a drive motor for rotating and driving the turntable, and an opening / closing lid for covering the information recording disk mounting recess. During the rotation driving of the information recording disk, the opening / closing lid covers the information recording disk mounting recess. When the information recording disk mounted on the turntable is taken out, the information recording disk placed on the turntable is opened and closed when the information recording disk mounted on the turntable is taken out.

Therefore, according to the disk drive device of the first aspect, since the turntable floats above the opening of the information recording disk mounting concave portion, the information recording device in which the user's finger is mounted on the turntable. The information recording disk can be easily taken out without touching parts at the periphery of the disk. According to the disk drive device of the second aspect, the turntable can be automatically lifted in conjunction with the opening of the open / close lid,
Therefore, the information recording disk mounted on the turntable can be easily taken out by a simple operation. Furthermore, according to the disk drive device of the third aspect, since the open / close lid side of the block chassis to which the turntable or the like is attached is levitated, the disk drive device is mounted on the levitated turntable. Since the surface of the information recording disk appears inclined toward the user side, in addition to the above-described effects, the user can naturally attach his / her palm to the inclined surface, and the information attached to the information recording disk. The recording disk can be easily taken out without a sense of incongruity. Further, according to the disk drive device of the fourth aspect, the disk drive device of the second and third aspects is a relatively inexpensive part that allows the opening and closing of the open / close lid to be performed by a spring force. With this configuration, a relatively inexpensive disk drive device can be obtained in addition to the above-described functions and effects. Further, according to the disk drive device of the fifth aspect, since the disk drive device of the second and third aspects is operated by using the power of the drive motor that opens and closes the open / close lid of the disk drive device, It can be configured with almost no use of separate parts, and in addition to the above-mentioned effects, a relatively inexpensive disk drive can be obtained.
According to the disk drive device of the sixth aspect, since the chucking plate is attached to the inside of the open / close lid according to the first to fifth aspects,
When the opening / closing lid is closed, the information recording disk mounted on the turntable can be suppressed.
