Embodiment Construction

[0030] refer to Figure 2 to Figure 8 , the mechanism unit 10A of the optical disc drive device according to the first embodiment of the present invention will be described. The mechanism unit 10A of the optical disk drive device shown in the figure is as described later, except that the shape (structure) of the counterweight is different, it is the same as the figure 1 The mechanism unit 10 of the shown conventional optical disk drive device has the same structure and has the same function. Therefore, a reference sign of 18A is attached to the balance weight. In addition, the same reference numerals are attached to the components having the same functions as those of the structural elements of the mechanism unit 10 of the conventional optical disc drive.

Abstract

The invention relates to an optical disc drive device for playing or recording and playing an optical disc, in particular to a mechanism unit of the optical disc drive device. It is used to increase the strength of the base plate against torsion and bending. The mechanism unit (10A) has the base plate (11), the base plate (11) is supported on the base frame at 4 points by means of 4 insulators made of elastic materials, and has a front (111) and a back (112), There is a substantially rectangular opening (11a) in the central part, and the counterweight (18A) disposed on the back side (112) of the base plate extends between and is mounted on both side ends of the base plate. Thereby, the structure of the bottom plate becomes a box shape.

Description

technical field [0001] The invention relates to an optical disc drive device for playing or recording and playing an optical disc, in particular to a mechanism unit of the optical disc drive device. Background technique [0002] An optical disc drive is a device for playing or recording / playing back an optical disc such as a DVD (digital versatile disc). In addition, DVD includes DVD-Video for digital video recorders, DVD-Audio for music, DVD-ROM for external storage devices such as computers, recordable DVD-R (Recordable), rewritable DVD-RAM, etc. . [0003] Such an optical disc drive device, as disclosed in Japanese Patent Document 1, Unexamined Patent Publication No. 2003-217210, includes: a disc tray for transporting an optical disc on the device main body; The chassis and the mechanism unit loaded on the chassis; the chassis includes: a load mechanism that withdraws from or feeds into the disc tray and moves the mechanism unit up and down. [0004] figure 1 It is a ...
