Problems solved by technology

Therefore, noise also tends to be generated due to shaking or vibration caused by the tilt or rotation of the disc
[0007] In the optical disc device disclosed in Japanese Patent Application Laid-Open No. 2000-21155, openings are plastically provided at several positions of the bottom plate (equivalent to the lower cover) opposite to the solenoid and the motor arranged on the disc tray bracket, but This is to dissipate the heat generated by functional parts such as solenoids and motors to the outside, not based on the technical idea of ​​reducing the overall thickness of the optical disc device
Moreover, there are no openings or cutouts in the case of the device itself, and it is not intended to be thinner from this point of view.

Embodiment Construction

[0032] First, use Figure 1 to Figure 6 A first embodiment of the present invention will be described.

[0033] like figure 1 As shown, the disc drive device 1 is equipped with an upper case 2 , a lower case 3 and a disc tray 4 . The upper casing 2 and the lower casing 3 are combined to form a casing 5 ( figure 2 ). Opposite to the housing 5 is a removable and insertable disc tray 4 .

[0034] figure 1 Indicates the state that the disc tray 4 has been pulled out from the housing 5. At the position of the disc tray 4 (the position where the disc is placed), the disc 6 can be installed on the disc tray 4, or the disc 6 can be removed from the disc tray 4. take it off.

[0035] on the other hand, image 3 It shows the state where the disc tray 4 is pushed into the casing 5, and information can be read from or written into the disc 6 at the position of the disc tray 4 (optical drive position).

[0036] Next, the direction in which the disc tray 4 is pushed into the casing...

Abstract

The present invention relates to an optical disk drive device used for loading and driving information recording optical disks such as CDs and DVDs, and for reading and writing information. In an optical disc drive, a part of the lower case is provided with a cutout or an opening in the upper and lower case housing functional parts such as a spindle motor inside to expose a part of the functional parts that are difficult to reduce in size in the vertical direction. In this way, the thickness dimension of the lower case and the necessary gap dimension in the case of no hole are all used as part of the vertical dimension of the above-mentioned functional components, so that they can be reduced without reducing the performance of the functional components. The vertical dimension of the entire device.

Description

technical field [0001] The present invention relates to an optical disk drive device used for loading and driving information recording optical disks such as CDs and DVDs, and for reading and writing information. Background technique [0002] Among the optical disk drives, there are products that can be installed in host computers such as notebook computers. However, since the main frame has been configured with several mechanisms in high density, this disc drive consists of a housing made of two housings up and down and a disc tray that can enter and exit the housing. A driving mechanism is arranged on one side of the frame. On the other hand, along with the reduction in thickness and miniaturization of the host computer, there is an increasing demand for reducing the size of the optical disk drive device, especially its thickness (dimension in the vertical direction). For example, the current average thickness of such an optical disc drive including the upper and lower c...
