Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

[0002]

2. Description of the Related Art Disk drives of this type can be roughly classified into the following two types in terms of structure. The first type of disk drive is a type in which a disk drive / playback mechanism such as an optical pickup, a disk motor, and a turntable is incorporated (mounted) in a tray, and the second type of disk drive is a type in which only an optical disk is loaded into a tray. And the disk drive / playback mechanism is built in the unit (housing) side. Hereinafter, the former (the first type of disk device) is also referred to as a tray built-in type disk device, and the latter (the second type of disk device) is also referred to as a unit built-in type disk device.

[0003] A disk device with a built-in tray is, for example,
JP-A-7-254202 (hereinafter, referred to as "prior art document 1") and JP-A-9-44955 (hereinafter, referred to as "prior art document 1").
This is referred to as “prior art document 2”. ). Further, a disk drive with a built-in unit is disclosed in, for example,
No. 0-269666 (hereinafter referred to as “prior art document 3”).

[0004] Prior art document 1 discloses a disk device configured to manually move a tray in and out. In Prior Art 1, a CD-ROM drive device includes a sub-chassis for supporting a tray, a tray sliding mechanism for slidably supporting the tray, an optical pickup unit, and a disk (CD-ROM) for rotationally driving. A turntable, a locking mechanism for locking the tray when the tray is moved to the disk replacement position, and a locking mechanism for locking the tray when the tray is moved to the disk mounting position. The locking mechanism includes a first locking member that locks the tray by engaging a locking hole formed in the chassis when the tray moves to the disk replacement position, and the tray moves to the disk replacement position. And a second locking member that locks the tray by engaging with the concave portion of the tray.

[0005] Prior art document 2 relates to a disk device incorporated in a notebook personal computer or the like as a CD-ROM drive device, and prevents a tray lock mechanism from being accidentally unlocked even when an impact is applied. It is an issue. The disk device disclosed in Prior Art Document 2
It has a tray, a lock lever, and a solenoid. The tray is configured to be able to move the mounted disk between a disk mounting position in the chassis and a disk replacement position pulled forward from the chassis. The lock lever locks the movement of the tray by engaging with a lock pin formed on the chassis when the tray is inserted into the disk mounting position. The solenoid drives the plunger to release the locked state of the tray by operating the lock lever when releasing the lock. The solenoid is disposed such that the moving direction of the plunger is at an angle to the moving direction of the tray.

The prior art document 3 realizes a light-weight, small-sized, low-cost disk reproducing apparatus by eliminating a dedicated driving source for a tray lock mechanism. The disk reproducing device disclosed in the prior art 3 moves the light beam position of the optical pickup to the recording area of the disk to a fixed position on the outer peripheral side, and rotates the lock lever via an ejecting projection attached to the optical pickup. The tray is released by operating. That is, the tray is unlocked using the power of the pickup feed motor. For this reason, it is not necessary to separately provide a power source for releasing the tray lock, and it is possible to reduce the size, weight, power consumption, and cost of the entire apparatus.

[0007]

However, in each of the prior arts 1 and 2, a dedicated drive source such as a solenoid or the like is required to release the locked state of the tray by the lock mechanism. This has led to increased costs.

On the other hand, prior art document 3 provides a disk reproducing apparatus (disk apparatus) capable of realizing light weight, small size, and low cost by eliminating the above-mentioned dedicated driving source. However, as described above, the disk device disclosed in the prior art document 3 is a unit built-in type disk device in which a disk drive / playback mechanism is built in a unit (housing) side. Is difficult. This is because each time the tray is moved in and out of the unit (disk unit main body), the disk drive / reproduction mechanism must be moved up and down with one end as a fulcrum, and that much space is required. Further, in a disk device with a built-in unit, the groove of the disk device body is inevitably complicated due to its structure.
In any case, since the disk drive with a built-in unit is difficult to reduce in thickness, it is not suitable for being incorporated into a small electronic device such as a notebook personal computer.

Accordingly, an object of the present invention is to provide a disk device with a built-in tray that does not require a dedicated drive source such as a solenoid and can be made thin.

Another object of the present invention is to provide a disk device with a built-in tray capable of reducing costs.

[0011]

According to the present invention, there is provided a disk drive (10) with a built-in tray in which a disk drive / playback mechanism is built in a tray (12), wherein a disk mounted on the tray is provided. Pickup unit (23) for reading data from the disc, a pickup drive unit (26) for moving the pickup unit in a predetermined disc radial direction (C, D), and the tray is housed in a main chassis (11). A lock mechanism (40) for locking the tray in a fixed position in the main chassis when the tray
And a lock release mechanism for releasing a lock state by the lock mechanism, wherein the pickup driving section (26) further moves the pickup section (23) further than its data reading range. The pickup section (23) having a portion extending outwardly in the disk radial direction by the predetermined distance so as to be movable outward in the disk radial direction by a predetermined distance;
Has an engagement protrusion (36a) protruding toward the lock mechanism, and the lock release mechanism (50) is disposed between the pickup section (23) and the lock mechanism (40). By the release operation, the pickup unit is engaged with the engagement protrusion in response to an unlocking operation in which the pickup unit once moves outward in the disk radial direction from the data reading range and then moves inward in the disk radial direction,
A tray built-in type disk device characterized in that it is configured to release the locked state by the lock mechanism.

The reference numerals in parentheses are provided for easy understanding of the present invention, and are merely examples, and it is a matter of course that the present invention is not limited to these.

Further, the first passage portion 521 allows the first columnar projection 514 to move in the predetermined disk radial direction (C and D directions).
The movement of the first cylindrical projection 514 in the moving direction (outward in the disk radial direction) of the linear portion 521a and the first cylindrical projection 514 guided along a direction (hereinafter, referred to as “moving direction”) parallel to the moving direction is regulated by the regulating wall 524. In this state, an escape portion 521b that allows the first cylindrical protrusion 514 to escape in a direction away from the pickup unit 23 side, and the first cylindrical protrusion 51
And a bent portion 521c that moves the first cylindrical protrusion 514 in a direction gradually moving away from the pickup portion 23 as the 4 moves toward the partition wall 523 side.
The distance (length) of the linear portion 521a is, of course, selected to a length at which the locked state by the lock mechanism 40 can be released.

FIG. 9 shows a state in which the hook arm 51 and the guide / regulator 52 are combined. This figure shows a state where the tray 12 is locked to the main chassis 11 by the lock mechanism 40. In this state, the first cylindrical projection 514 is in contact with the regulating wall 524, and the second cylindrical projection 515 is in contact with the partition wall 523. In other words, the hook arm 51 is located at the position moved most outward in the disk radial direction.

On the other hand, in the locked state by the lock mechanism 40, since the pickup section 23 is moving within the data reading range shown in FIG. 512
Does not move outward in the disk radial direction. FIG. 9 shows a state in which the pickup unit 23 is at the outermost position in the disk radial direction in the data reading range. As is apparent from FIG. 10, at this time, although the engagement projection 36a of the pickup portion 23 comes closest to the projection 512 of the hook arm 51, they do not engage with each other.

Next, the unlocking operation by the unlocking mechanism 50 will be described with reference to FIGS.

First, the operator turns on (unlocks) the switch button 16 (FIG. 1). This allows
A switch-on command (that is, a lock release command) is transmitted from the switch button 16 to a controller (not shown). In response to this switch-on command (unlock command), the controller first stops the rotation of the disk motor 27. After confirming that the rotation of the disk motor 27 has stopped, the controller operates the pickup driving motor 2.
9, the pickup unit 23 is moved outward of the data reading range in the disk radial direction as shown in FIG.

At this time, the engaging projection 36a of the pickup section 23 collides with the projection 512 of the hook arm 51, and as a result, as shown by the arrow F in FIG.
A force acting in a direction away from the pickup unit 23 acts on the reference numeral 12. The first cylindrical projection 514 of the hook arm 51 escapes to the escape portion 521b in the first passage portion 521 of the guide / restriction portion 52. As a result, as shown in FIG. 10, the arm main body 511 of the hook arm 51 bends away from the pickup section 23 against the urging force of the resin spring section 513.

When the pickup portion 23 further moves outward in the radial direction of the disc, the engagement protrusion 3 of the pickup portion 23
6a gets over the projection 512 of the hook arm 51.
At this time, the hook arm 512 returns to the original state by the urging force of the resin spring portion 513. This state is shown in FIG.

Next, the controller drives the pickup driving motor 29 to move the pickup section 23 inward in the disk radial direction as shown by an arrow F as shown in FIG. Thereby, the pickup unit 23
When the hook projection 51a of the hook arm 51 and the projection 512 of the hook arm 51 are engaged (coupled),
As shown by, the disk moves inward in the moving direction parallel to the disk radial direction. Since the engaging portion 511a of the hook arm 51 is engaged with the distal end portion 433a of the second arm portion 443 of the lock plate 44, the arm 511a is opposed to the urging force of the coil spring 45 as shown by the arrow H. Plate 44
Rotates clockwise around its arm axis 441. Since the first arm portion 442 of the lock plate 44 is connected to the distal end of the connection arm 424 of the lock plate 42, the lock plate 42 rotates around its lock shaft 421 counterclockwise as shown by the arrow I. To rotate.

As shown in FIG. 13, the optical pickup 2
When the disk 3 is further moved inward in the disk radial direction, the engagement between the cylindrical portion 422 of the lock plate 42 and the lock portion 41 is released, and the locked state of the lock mechanism 40 is released. At this time, the first cylindrical projection 514 of the hook arm 51 is
At the innermost end of the straight portion 521a of the passage portion 521 in the disk radial direction.

By the way, the tray 12 is mounted on the main chassis 1.
It is constantly urged by an urging means (not shown) in a direction (arrow A direction) that projects forward from 1. Therefore,
When the lock state by the lock mechanism 40 is released, FIG.
As shown in FIG. 4, the tray 12 moves in the direction of arrow A. With the movement of the tray 12 and the movement of the pickup unit 23 inward in the disk radial direction, the hook arm 5
The first cylindrical projection 514 moves along the bent portion 521c of the first passage portion 521, and as a result, the hook arm 5
The one protrusion 521 moves in a direction away from the pickup unit 23. Thereby, as shown in FIG. 14, the connection (engagement) between the projection 521 of the hook arm 51 and the engagement projection 36a of the pickup unit 23 is released.

When the tray 12 protrudes further forward (in the direction of arrow A) from the main chassis 11, the urging force of the urging means 44 (coil spring 45) is applied to the tray 12, as shown in FIG.
The lock plate 41 and the hook arm 51 return to the normal position. That is, the arm plate 44 of the urging means 44 rotates counterclockwise around the arm axis 441 as indicated by the arrow J. As a result, the lock plate 42 of the lock mechanism 40 has its lock shaft 421
Is rotated clockwise as shown by the arrow K direction, while the hook arm 51 moves outward in the movement direction as shown by the arrow L direction. In this way, the locked state by the lock mechanism 40 is released by the lock release mechanism 50.

As described above, in the present invention, the pickup driving section 26 extends outward by a predetermined distance in the radial direction of the disk, and the pickup section 23 is provided with the engagement projection 36a.
The lock state by the lock mechanism 40 can be released only by disposing the lock release mechanism 50 between the pickup unit 23 and the lock mechanism 40. Therefore, as in the related art (prior art documents 1 and 2), a dedicated power source such as a solenoid for releasing the locked state of the lock mechanism can be omitted, and the cost can be reduced. Further, a dedicated circuit for driving the solenoid is not required, and a driving circuit for driving the pickup driving motor 29 can be used, so that the cost of the circuit can be reduced. Also, the disk device 10 according to the present invention
Since it is a disk device with a built-in tray instead of a disk device with a built-in unit as disclosed in Prior Art Document 3, it can be made thinner.

As described above, the present invention has been described with reference to the preferred embodiments by way of example. However, it is needless to say that the present invention is not limited to the above embodiments. For example, in the above-described embodiment, a case where the present invention is applied to a CD-ROM drive device has been described as an example. However, the present invention is not limited to this, and a CR-R drive device or a CR-RW
Needless to say, the present invention can be applied to a drive device and a DVD-RAM drive device.

[0047]

As is apparent from the above description, according to the present invention, the pickup drive section extends outwardly in the radial direction of the disk by a predetermined distance, and the pickup section is provided with an engagement projection. The lock state by the lock mechanism can be released only by arranging the lock release mechanism between them. Therefore, a dedicated power source such as a solenoid for releasing the locked state of the lock mechanism, as in the conventional disk device with a built-in tray, can be eliminated, and the cost can be reduced. Further, a dedicated circuit for driving the solenoid is not required, and a driving circuit for driving the pickup driving motor 29 can be used, so that the cost of the circuit can be reduced.
