Problems solved by technology

Due to this structure, when the disk unit is impacted by falling or the like, the impact deforms the support portion and the biasing mechanism to cause the shaft portion to fall off. As a result, the entire assembly supported on the intermediate base (including Turntable and optical pickup, etc.) fall off from the base of the device

Embodiment approach 1

[0030] figure 1 It is a perspective view showing the disk drive of Embodiment 1. The disk device includes a main chassis 10 , a rotary chassis 20 rotatably supported by the main chassis 10 , and a tray 4 reciprocally supported by the main chassis 10 . The tray 4 has a mounting surface 40 that holds the disk medium 100 horizontally, and is horizontally conveyed between a storage position inside the disk device and a discharge position outside the disk device.

[0031] The following instructions are as figure 1 As shown, the direction perpendicular to the mounting surface 40 of the tray 4 is defined as the Z-axis, and the moving direction of the tray 4 is defined as the Y-axis. In addition, let the direction perpendicular to the Y axis and the Z axis be the X axis. Here, regarding the Z-axis, the direction from the tray 4 toward the disk medium 100 is defined as a positive side, and the opposite direction is defined as a negative side. In the Y-axis, the direction in which...

Embodiment approach 2

[0049] Figure 10 and Figure 11 It is a perspective view showing the negative side in the Z-axis direction as the upper side and the positive side in the Y-axis direction as the lower left side. Figure 10 Indicates the state in which the rotating assembly 2 is about to be assembled to the disk drive of Embodiment 2, Figure 11 It shows the state after the rotary unit 2 is assembled to the disk drive.

[0050] Such as Figure 10 and Figure 11 As shown, in the main chassis 10 , protrusion support portions 5 a , 5 b for supporting the protrusions 21 a , 21 b of the rotating chassis 20 are respectively formed on the outer side of the rotating chassis 20 in the X-axis direction. The protrusion support parts 5 a and 5 b each have side walls 6 a and 6 b extending in the Y-axis direction from the outer peripheral wall 103 of the main chassis 10 . The side walls 6a, 6b each have a horizontal end face (end face parallel to the XY plane) facing the negative side of the Z-axis dir...

Embodiment approach 3

[0060] Figure 13 and Figure 14 It is a perspective view showing the negative side in the Z-axis direction as the upper side and the positive side in the Y-axis direction as the lower left side. Figure 13 Shown is the state of the disk drive in Embodiment 3 just before the rotation unit 2 is assembled, Figure 14 Shown is a state in which the rotary assembly 2 is assembled to the disk drive. In the disk drive according to the third embodiment, the protrusion support portions 5a, 5b of the main chassis 10 are configured in the same manner as in the second embodiment. That is, the insertion direction of the protrusions 21a, 21b into the protrusion supports 5a, 5b is the Y-axis direction, whereby the structures of the protrusions 21a, 21b are not easily detached from the protrusion supports 5a, 5b. In addition, in this Embodiment 3, the same protrusion 22a, 22b as Embodiment 1 is formed in the front-end|tip part of the protrusion part 21a, 21b of the rotating chassis 20. As ...

Abstract

A disk device comprises a traverse chassis (20) for supporting a turntable (30) or the like, and a main chassis (10) for turnably supporting the traverse chassis (20). The traverse chassis (20) has a pair of bosses (21a, 21b) coaxial with each other, while the main chassis (10) has boss supports (1a, 1b) supporting the bosses (21a, 21b) of the traverse chassis (20). The front ends of the bosses (21a, 21b) are formed with projections (22a, 22b), which abut against the boss supports (1a, 1b), thereby inhibiting the boss supports (1a, 1b) from being deformed in the direction to move away from each other, thus preventing the bosses (21a, 21b) from falling off the boss supports (1a, 1b).

Description

technical field [0001] The present invention relates to a disc device for recording and / or reproducing information in a compact disc player or the like, and for writing and / or reading information on a disc-shaped information recording medium. Background technique [0002] It has long been known that a disk device has a loading mechanism for transporting a disk-shaped information recording medium (hereinafter referred to as a disk medium) between a storage position inside the device and an ejection position outside the device. Such a disc device is disclosed, for example, in Japanese Unexamined Patent Publication No. 2002-93013 (page 7, Figure 2 ~ Figure 4 ) is published. In such a disk device, in order to avoid interference with the conveyed disk medium, a turntable for rotating the disk medium, an optical pickup, and the like are mounted on a vertically movable base (referred to as an intermediate base). [0003] In such a conventional disk device, a pair of shaft portion...
