Problems solved by technology

[0004] However, in the case of the disc player described above, the position of the chassis in the direction of the main surface of the disc is limited by the rotation shaft, while the position of the chassis in the direction of the main surface of the disc is also limited by the guide.
That is, the movement of the chassis is limited by the redundancy of the shafts and guides
Therefore, due to minute deformation of members such as the chassis or the guide, interference is generated between the shaft and the bearing or between the rail and the guide, so that the rotational movement of the chassis cannot be performed smoothly.

Embodiment Construction

[0042] Referring to the drawings, various embodiments of the invention will now be described.

[0043] Figure 1 to Figure 3 A disk player is shown as an embodiment of the present invention.

[0044] like figure 1 As shown in , a rectangular loading tray 1 is installed movably in the directions of an arrow a (ie, an opening direction) and an arrow b (ie, a closing direction) relative to a base 2 . On the loading tray 1, a disc-shaped rotary tray 3 is rotatably mounted with a rotating shaft 3a as its fulcrum. On the rotary tray 3, three disk accommodating cells 3b are prepared.

[0045] figure 2 A plan view showing the above disk player. In the loading tray 1, a driving motor 4 is provided so that the driving motor 4 rotates the rotatable tray 3 and moves the loading tray 1 in the directions of arrows a and b.

[0046] First, a driving mechanism of the rotary tray 3 will be roughly explained. The driving force from the driving motor 4 is transmitted to an internally too...

Abstract

A disc player is provided with: a turn table for rotating an information record disc, which is placed on the turn table; a clamper for holding the information record disc between the clamper and the turn table; a chassis on which at least one of the clamper and the turn table is mounted and which has a rotation shaft parallel to a main surface of the information record disc held between the clamper and the turn table; a driving device for transmitting a driving force to the chassis so as to rotate the chassis with the rotation shaft at a rotation axis; and an optical pickup for at least reading a signal from the information record disc held between the clamper and the turn table while the disc is rotated on the turn table. A gap is prepared between the rotation shaft and a bearing for the rotation shaft in a direction parallel to the main surface.

Description

technical field [0001] The present invention relates to a disc player, which clamps a disc by rotating a chassis on which a clamper or a turntable is mounted. Background technique [0002] A disc player clamps and holds a disc between a holder and a turntable mounted on a rotatable chassis. The chassis is configured with a central axis of rotation parallel to a major surface of the disc. The shaft is rotatably supported by a bearing provided on a tray or the like. By rotating the chassis relative to the tray about a rotating shaft as a center by means of an elastic member, a cam, etc. to swing the turntable, the disk is clamped and fixed between the turntable and the holder above the turntable. [0003] On the other side of the chassis, a guide is made. The guide member is capable of engaging a guide rail extending in a direction perpendicular to the major surface of the disk to guide rotational movement of the chassis. Thanks to this guide, it is possible to improve the...
