Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a CD-ROM,
The present invention relates to an optical disk drive such as a DR and a CD-RW, and more particularly to an optical disk drive having a tray-type loading mechanism.

[0002]

2. Description of the Related Art At present, personal computers and the like have C
An optical disk drive device such as a D-ROM is mounted almost as a standard, and the loading method of the optical disk drive device is a tray type because of operability when handling a bare recording medium such as a CD-ROM disk. The adoption of a loading mechanism is dominant. In this tray-type loading mechanism, a tray portion on which an optical disk is placed is provided with a concave disk guide portion which is set slightly larger than the outer shape of the disk. The optical disk is drawn into the apparatus from the front panel opening and transported to the recording / reproducing position in the apparatus, the mechanical chassis provided with the spindle motor is raised, and the spindle motor turntable is inserted into the reference hole provided in the optical disk. The center portion is fitted, and the optical disk is set in such a manner as to be sandwiched by the clamp mechanism provided at the upper part in the drive device, and the loading is completed.

[0003]

By the way, it is necessary to reduce the vertical movable stroke of the mechanical chassis due to the restriction of the form factor in the height direction of the drive device. ,
It is set to about several mm. For this reason, if the optical disc is carelessly (rapidly) placed on the tray, the optical disc may be loaded with the optical disc protruding from the disc guide portion. , Deform the mechanical part,
In the worst case, there is a possibility that the important optical disk of the user will be damaged.

In an optical disk drive device having a tray-type loading mechanism, a low friction member is provided on a turntable in the device so as to be able to come and go with respect to the disk carrying surface, and the low friction member is used to load an optical disk during loading. There has been proposed an auto-loading disc player in which the misalignment is corrected so that the disc is centered on the turntable with high precision (Japanese Patent Publication No. 6-75325). However, in this conventional technique, when the optical disk is lifted from the tray by the disk clamp mechanism and pressed against the disk holding surface of the turntable, the optical disk is placed in an inclined state on the tapered surface of the centering hub. It corrects the slight inclination and misalignment of the optical disk during clamping, as described above, and assuming that the optical disk is correctly placed on the disk guide of the tray, the optical disk protrudes from the disk guide of the tray. However, it is not possible to cope with a large positional deviation in a case where the load is performed in a loaded state, and the above-described problem cannot be solved.

The present invention has been made in view of the above circumstances. Even if an optical disk is loaded without correctly placing the optical disk on the disk guide portion of the tray, the optical disk can be returned to the disk guide portion, and the failure of loading or the like can be prevented. It is an object of the present invention to provide an optical disk drive device that can prevent such an error.

[0006]

To achieve the above object, the invention according to claim 1 has a tray provided with a disk guide portion on which an optical disk is mounted, and the tray is mounted on the optical disk mounting surface. A tray-type loading mechanism is provided for moving in substantially parallel directions to load / unload inside / outside of the front panel opening. At the time of loading, an optical disk placed on the tray is transported to a recording / reproducing position in the apparatus by the loading mechanism. And record information on the optical disc /
In a reproducing optical disk drive device, when a tray of the loading mechanism moves, a disk position correcting member for returning an optical disk whose mounting position is shifted with respect to the disk guide portion to the disk guide portion while passing near the tray. Is provided in the housing of the drive device. That is, in the optical disk drive device of the first aspect, even when the optical disk is loaded without correctly placing the optical disk on the disk guide portion, the disk position correcting member provided in the housing of the drive device accompanies the movement of the tray. The optical disk can be returned to the disk guide portion by contacting the end surface.

In the optical disk drive device of the first aspect, the disk position correcting member provided on the housing of the drive device is not particularly limited, but the disk position correcting member comes into contact with the end surface of the optical disk and the optical disk guides the disk. It is desirable that the optical disk be made of a material that is not easily scratched.

Therefore, in the invention according to claim 2, claim 1
In the optical disk drive device described above, the disk position correcting member that passes near the tray when the tray moves is a resin member. As described above, by using the resin member as the disk position correcting member passing near the tray, it is possible to more safely return the optical disk protruding from the disk guide portion (without damaging the optical disk) to the disk guide portion. it can.

When the disk position correcting member that passes near the tray when the tray moves is made of a resin member, when the housing of the drive device is made of resin, the disk position correcting member is integrally formed with the housing. Although it can be formed, if the housing of the drive device is made of sheet metal, a resin-made disk position correcting member is formed as a separate component and assembled to the housing. For this reason, parts costs and assembly costs are incurred, resulting in increased costs.

According to a third aspect of the present invention, in the optical disk drive device according to the first aspect, the disk position correcting member passing near the tray when the tray is moved is drawn directly from the sheet metal casing. It is characterized by being formed integrally with the tray in the vicinity of the tray by processing or cutting and bending. As described above, the disk position correcting member passing near the tray is integrally extended directly from the sheet metal housing to the vicinity of the tray by drawing or cutting and bending, thereby increasing the cost of parts and assembly. Can be suppressed.

In the optical disk drive of the first aspect,
A disk position correcting member passing near the tray is provided in the housing of the drive device. However, when the length of the disk position correcting member is short and the amount of the optical disk protruding from the disk guide portion is small, the optical disk May not be reliably returned to the disc guide. When the loading is completed, the optical disk is chucked (clamped) by the spindle motor at a position where a predetermined clearance is maintained with respect to the disk guide portion so as not to hinder rotation. It will move upward. If the amount of upward movement of the optical disk at the time of completion of the loading is small, the length of the disk position correcting member provided on the housing of the drive device is changed (for example, the length of the disk position correcting member is set closer to the tray surface). Length) can cope with the above-described problem of the return failure. However, if the amount of upward movement of the optical disk at the time of completion of loading is large, the optical disk that has moved upward may depend on the installation position of the disk position correction member. The disk position correcting member may come into contact with the disk position correcting member, and the disk position correcting member may not be provided.

Therefore, the invention according to claim 4 is based on claim 1,
4. The optical disk drive according to 2 or 3, wherein a groove is formed on the tray in parallel with a direction in which the tray moves, and the disk position correcting member traces the groove with a predetermined clearance as the tray moves. Is provided on the housing of the drive device at a position outside the disk guide when the loading is completed. In this manner, a groove parallel to the direction in which the tray moves is formed on the tray, and a member for tracing the groove with a predetermined clearance accompanying the movement of the tray as a disk position correcting member is provided outside the disk guide when loading is completed. Is provided in the housing of the drive device at a position where the disk position correction member is located outside the disk guide when the optical disk is moved upward upon completion of loading, and therefore does not contact the optical disk. The disk position correction member can be brought close to the vicinity of the optical disk, and the optical disk can be surely returned to the disk guide portion even if the optical disk is loaded without being correctly placed on the disk guide portion. Further, since the disk position correcting member is located outside the disk guide portion when loading is completed, even if the optical disk moves upward due to the loading operation, there is no trouble such as interference with the disk position correcting member. .

By the way, the structure of claim 4 is an effective means for preventing failure of loading or the like. However, when the disk position correcting member is a separate member from the housing of the drive device, the cost increases (the cost of parts and the cost of assembly are reduced). Up). In addition, when extending integrally from the sheet metal housing,
Since the material is metal, in the worst case, there is a concern that the optical disc may be damaged.

According to a fifth aspect of the present invention, in the optical disk drive according to the fourth aspect, a member for tracing the groove with a predetermined clearance is formed integrally with a front panel opening through which the tray moves back and forth. It is what it was. The optical disk drive device is provided with a front panel provided with operation switches, display LEDs, an eject button, and the like. Since the front panel is usually formed of resin, the groove is traced with a predetermined clearance. By forming the member integrally with the front panel opening where the tray moves back and forth,
There is almost no increase in the cost of parts, and the optical disk can be returned to the disk guide portion more safely because it is made of resin. In addition, it can be easily set at a position outside the disc guide portion when loading is completed, because of the mounting position of the front panel.
