Embodiment Construction

[0030] Hereinafter, one embodiment of the disk drive device of the present invention will be described based on the drawings. In the following, an optical disk drive device is taken as an example for description, but the structure of the main part can also be applied to other disk drive devices. In addition, the same code|symbol is attached|subjected to the same or equivalent structural part among each figure, and the overlapping description is abbreviate|omitted.

[0031] figure 1 It is a perspective view showing the configuration of an optical disk drive device according to an embodiment of the present invention.

[0032] The optical disk drive device 1 has a structure in which a tray 40 in a state where an optical disk is loaded can be introduced into and drawn out from a thin box-shaped casing (device casing) 10 .

Abstract

A disk drive device that can prevent warping deformation in upward and downward directions of a disk tray and can prevent vibration in a warping deformation mode without producing a rattle vibration is provided. A disk drive device has a casing and a disk tray on which the spindle motor and the pickup are mounted; and a pair of parallel first and second guide mechanisms that slidably supports the disk tray so as to eject the disk tray from the casing to the outside. In the disk drive device, in a center part in a width direction along the disk mount surface of an introduction side distal end part of the disk tray, an introduction side abutment part having a groove section or a protruding portion is formed, and an inner part abutment part formed on an elastic member is installed on an inner side inner wall part.

Description

technical field [0001] The present invention relates to a disk drive device for recording and reproducing information, and more particularly to a tray-type disk drive device in which disks are mounted on trays drawn out from a device case and each tray is introduced into the device case. Background technique [0002] As a tray-type disk drive device, Patent Document 1 (Japanese Patent Application Laid-Open No. 2002-279717) discloses a structure in which, on the back side of the disk mounting surface (surface) of the tray, the height (thickness direction (vertical direction) )) is protrudingly provided with a rib-shaped contact portion, which is located in the central part of the width direction (left-right direction) on the introduction side (rear side in the front-rear direction) of the tray in the import-export direction (front-rear direction) of the tray, and in the tray The chassis on the fixed side, where the fixed position is opposite to the contact portion, is provide...
