DETAILED DESCRIPTION OF THE INVENTION [0001] The present invention relates to a disk drive.
In particular, note-type personal computers are used as CD-ROM drive devices.
The present invention relates to a disk device incorporated in a computer or the like. [0002] 2. Description of the Related Art For example, databases and software
As a storage medium for storing
Compact disc (12cm in diameter)
Or 8 cm) is being used. As a result,
Inside the case so that it can be incorporated into a laptop computer
Development of built-in CD-ROM drive device
Has been done. In a conventional apparatus, a disk on which a disk is
The tray is driven by a motor and the tray moves
Then put the disc on the turntable in the tray,
Return the tray to the housing by the driving force of the motor again.
ing. However, drive the tray with a motor as described above.
In the moving method, a motor and a drive for driving the tray are used.
A transmission mechanism that transmits power to the tray is required,
It is difficult to make the device smaller and thinner,
It could not be incorporated into the housing of the computer. [0004] In addition, a burden is imposed on the motor that drives the tray.
It is necessary to reduce the weight of the tray to reduce
Spindle motor for rotating the disk and the disk
Pickup that reads stored information on chassis side
Had been provided. Therefore, the motor and the transmission device as described above
The tray is not required, and the tray inside the housing is manually operated.
To the disk mounting position or the disk replacement position outside the enclosure.
A disk device having a configuration is being developed. [0005] SUMMARY OF THE INVENTION However, the above disk
In the disk drive, the entire disk is placed in a circular
The disc is placed on the disc loading section of the
Of the disc is larger than the outer diameter of the disc.
Had been established. As a result, in the conventional disk drive,
The width of the tray is too large,
Because the pace needs to be secured, the entire device is
It was difficult to reduce the size. [0006] In addition, the conventional disk drive uses a disk.
Spindle motor to rotate and stored on disk
Pickup on the chassis side to read the information
The spindle motor, pickup and disk
Position when the tray stops.
It is necessary to increase the tray movement accuracy.
It was important. On the other hand, to make the tray move smoothly
Must provide clearance for the tray drive mechanism.
And improve the relative position accuracy between the pickup and the disc
It was difficult. Accordingly, the present invention has achieved a solution to the above problems.
It is intended to provide a disk device. [0008] Means for Solving the Problems To solve the above problems,
Therefore, the present invention has the following features. Claim 1
The described invention may be applied to the disk mounting position inside the housing or outside the housing.

The second storage portion is formed wider than the first storage portion for storing
And a storage sectionIt is characterized by having. Therefore, according to the first aspect of the present invention,
A part of the disc protrudes from the tray
And a motor for rotating the disk
Pickup to read information stored on the disc.
A tray on the trayThe first to store the tray in the chassis
Storage section and wider than the first storage section for storing the disc
And a second storage portion formed.The width of the tray
Reducing the dimensions to reduce the tray movement space
It is possible to reduce the size of the device.
Can be. In addition, the motor that drives the disk
The tray is integrated with the tray so that
The relative position accuracy between the disc and the pickup
The reading accuracy of the disc
Can be improved. [0010] [0011] BRIEF DESCRIPTION OF THE DRAWINGS FIG.
The form will be described. FIGS. 1 to 4 show the data according to the present invention.

You. The tray 2 has a part of a disk (not shown).
The width of the disc is larger than the outside diameter of the disc so that it protrudes from the disk 2.
Is formed to be small, and is manually operated.
Slide in the A and B directions to replace the disk
To the landing position. For this reason, the tray 1 is provided with A, B
Drive mechanism (motor and transmission mechanism, etc.)
Is not provided), and the number of parts decreases accordingly.
Therefore, miniaturization and thinning have been achieved. 10 is
Storage section that stores each of the above mechanisms in the chassis(Claim 1
(Corresponds to the "first storage unit")10a and from tray 2
A protruding disc to protect a protruding disc

Equivalent to)10b. In addition, cover part10b's
The lower part is a space, for example, a node where the device 1 is assembled.
Other devices in the laptop PC will be installed. Reference numeral 11 denotes a front bezel, which is fixed to the front end of the tray 2.
And slides in the A and B directions integrally with the tray 2. This
When pulling out the tray 2 in the center of the front bezel 11
Switch for releasing lock by lock mechanism 8
A button 12 is provided. Therefore, in the state shown in FIG.
When the switch button 12 is turned on, the
Surface bezel 11 protrudes forward (A direction) about 5 to 10 mm
To facilitate the operation of pulling out the tray 2. As shown in FIGS. 3 and 5, the tray 2

Opposite surface 2a and pick formed in disk opposite surface 2a
Opening and turntable opening 2b and disk pair
A finger is inserted when removing the disc placed on the facing surface 2a.
And an arc-shaped opening 2c for taking out a disk to be taken out.
You. The disk facing surface 2 a
The width dimension is larger than the outer diameter of the disc so as to cover the receiving portion 10a.
It is smaller and can cover about 2/3 of the disk
It is formed as follows. Therefore, as shown in FIG.
Disk D_AIs the right edge of the tray 2 facing the disk
It protrudes to the side from 2a. Therefore, disk D_ATake
When ejecting the disc, the disc protruding from the disc facing surface 2a
D_AOf the disk D
_AThere is no need to provide a recess in the tray 2 for gripping
In addition, the entire right side of tray 2 is disk D_AGrasp
It is a space to do. Therefore, disk D_AGrasp
When the finger touches the disk, one finger protrudes from the disk facing surface 2a.
Disk D_AThe other finger into the opening 2c.
Insert disk D_AOn the opposite edge
Apply The opening 2c is located in the left direction of the tray 2.
But not in the empty space at the corner of Tray 2.
So that the dimensions on the left side of tray 2 are as small as possible.
ing. Therefore, the width of the tray 2 is significantly smaller.
The tray 2 is much smaller than before.
ing. This makes it possible to reduce the size of the device 1,
As described above, the chassis 10 also corresponds to the width of the tray 2
As a result, the width of the storage portion 10a is reduced,
Cover to protect discs that protrude from Ray 2
The portion 10b projects laterally from the storage portion 10a. In FIG. 5, as indicated by a dashed line,
D_APart of the sheet protrudes from the disk facing surface 2a of the tray 2.
Since the tray 2 is formed like this,
The disc gripping direction is not restricted, it protrudes from the tray 2.
Disc D_AGrip the edge of the disk anywhere

Of course you can. In the above embodiment, the disk is
Although it is configured to be clamped to the turntable,
The present invention is not limited to a configuration in which a disc is placed on a tray.
Needless to say, this can also be applied. [0057] As described above, according to the first aspect of the present invention,
If the tray is part of the disc
And drive the motor to rotate the disk.
To read information stored on the disc.
Cup on trayPut the tray in the chassis
From the first storage section and the first storage section for storing a disk
And a second storage portion formed wide.Because the tray
The width of the tray to reduce the tray movement space
It is possible to reduce the size of the device.
Can be In addition, a motor that rotates the disk
And the pickup are provided integrally with the tray.
The relative position accuracy between the disc and the pickup
Disc reading is not affected by movement position accuracy
Accuracy can be improved. [0058]
