DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disk drive such as an optical disk drive, and more particularly to a disk transfer means for transferring a disk for recording and reproduction between a disk rotating means and the outside, and a disk transfer for transferring a disk. The present invention relates to a disk device provided with elevating means for vertically moving a chassis provided with rotating means or a frame elastically supporting the chassis.

[0002]

2. Description of the Related Art In an optical disk drive, a transfer means for transferring a disk to a disk rotating means in the apparatus or discharging the disk to the outside of the apparatus is necessary for exchanging a disk for recording and reproducing. is there.

As an optical disk device which can be exchanged in a single disk state, there is, for example, one proposed in Japanese Patent Application Laid-Open No. 3-248467. In the prior art disclosed in this prior application, a rotatable guide roller portion for holding the disc from above and below is provided immediately after the disc insertion slot, and the disc is sandwiched from above and below on the back side in the insertion direction. And a driving roller unit that is driven to rotate with
When a disc is inserted, the disc is first sandwiched between guide roller portions and guided by a drive roller portion on the back side. When the disk reaches the drive roller unit, the disk is nipped by the drive roller unit, and the disk is pulled further inward by the rotation of the drive roller unit. Thereafter, the guide roller unit and the roller on the disk lower surface side of the drive roller unit Are respectively lowered, and the disk is mounted on a spindle which is disk rotating means. On the other hand, when the disc is ejected, the rollers on the lower surface side of the guide roller section and the drive roller section are respectively raised, the disc is sandwiched between the guide roller section and the drive roller section, and the drive roller section is inserted in the opposite direction to the insertion. By rotating, the disc is sent out.

In addition, it is necessary to prevent interference between the disk and the disk rotating means on which the disk is mounted at the time of inserting / ejecting the disk. Therefore, for example, at the time of inserting / ejecting the disk, the disk rotating means is required. It was lowered by the lifting means.

Japanese Patent Application Laid-Open No. Hei 5-144150 proposes an example of this type of elevating means in consideration of thinning. In the prior art disclosed in this prior application, the disk is transported using a tray on which the disk is placed and moves in the front-rear direction with respect to the housing. A support pin as a rotation axis extending in the left-right direction with respect to the housing is provided on a side of the support plate, which supports the rotation drive mechanism with the elastic body, away from the spindle motor, and the support pin as the rotation axis of the support plate is provided. A support pin for supporting the support plate is provided on the other end of the provided side, and the support plate is mounted so as to move back and forth in conjunction with the operation of the tray. Furthermore, a cam groove for changing the height is provided on the inner side of the side surface of the housing, and the support pin and the cam groove are engaged. When the disc is inserted / ejected, the support plate moves back and forth in conjunction with the operation of the tray. Thus, relative movement occurs between the cam groove and the support pin. As a result, the support height of the support pin changes according to the groove shape of the cam groove, and the support plate moves up and down to raise and lower the disk table.
The disc and the disc table do not interfere with each other during ejection.

[0006]

In an optical disk apparatus, if the disk is damaged, there is a possibility that recording and reproduction may be hindered.

However, Japanese Patent Application Laid-Open No. 3-24836 discloses
According to the proposal of the disk transfer means described in Japanese Patent Application Publication No. 7 (1994), at the time of insertion / ejection of the disk, the rollers pinch a part of the disk surface and transport the disk by its rotation, thereby damaging the disk surface. There were concerns.

Further, in order to be able to be built in a portable personal computer or the like, it is necessary to reduce the size and thickness of the device, and it is necessary to effectively use the space in the housing. For this reason, the pickup for recording and reproducing data on and from the disk is transported in a substantially diagonal direction of the housing.

[0009] However, Japanese Patent Application Laid-Open No. Hei 5-14415 discloses
According to the proposal of the lifting means described in Japanese Patent Publication No. 0, when the pickup is arranged so as to be transported in a diagonal direction, the pickup moves closer to the side surface of the housing at the position for recording / reproducing the outermost periphery of the disk. The distance between the chassis provided so that it can be provided or the frame that elastically supports it and the housing becomes narrower, and the rotating shaft for rotating and supporting the chassis or the frame is located at a position away from the disk rotating means that drives the disk to rotate. The arrangement is difficult, and the shaft must be arranged on the side close to the disk rotating means. Therefore, in this case, in order to prevent interference between the transferred disk and the disk rotating means, it is necessary to increase the tilt angle of the chassis or the frame,
There is a problem that the thickness of the device is increased.

[0010] The present invention has been made in view of the above points,
The purpose thereof is to use a disk alone as a recording medium when exchanging a disk, and to insert / eject the disk without damaging the disk surface, and to raise and lower the disk suitable for miniaturization and thinning. It is an object of the present invention to provide a disk device having means.

[0057]

As described above, according to the present invention, since the disk is held from the side, there is no risk of damaging the surface of the disk when inserting / ejecting the disk. Further, compared to a configuration in which the disk is sandwiched from above and below, it is easier to make the mechanism flat. Further, a disk device capable of handling a plurality of disk diameters can be realized only by adding a disk diameter detecting means for detecting the disk diameter. In addition, since the pickup transfer direction is oblique to the disc insertion direction, and the rotation axis for vertically moving the frame on which the pickup is mounted is arranged so as to be orthogonal to the pickup transfer direction, the insertion direction is Since the rotating shaft can be accommodated within the width of the frame as viewed from above, there is no need to take extra device width, and the device can be made more compact.
