Embodiment Construction

[0053] like figure 1 and figure 2 As shown, the optical disc device 2 that has implemented the present invention is mounted on a vehicle and used, and possesses: an automatic loading optical disc 3 (refer to Figure 5 ) loading mechanism, a disc playback mechanism 4 for reproducing and recording data on the optical disc 3; a housing 5 for accommodating the disk playback mechanism 4;

[0054] The case 5 is thin and formed in a size capable of being built into a notebook computer (not shown), and is swingably held on the holding base 7 via a shock absorber 8 . figure 1 The figure is omitted, and on the top of the holding base 7, a box-shaped cover 9 capable of covering the left and right sides, the front and the back, and the top of the housing 5 is attached. An exposing opening 9 a exposing the front surface of the front cover 6 is formed on the front surface of the outer cover 9 . When the optical disc device 2 is mounted on a vehicle, the holding base 7 and / or the cover 9...

Abstract

An optical disc device capable of prohibiting thickness and width and absorbing external vibration is disclosed. The vehicle optical disc device (2) includes a disc playback mechanism and a casing (5). The casing (5) is mounted on a holding pedestal (7) via three vibration absorbers (8). The casing (5) is provided with an upper cover (11) and a lower cover (12). The lower cover (12) includes a mechanism receiving part (12a) and a wing part (12b). A left support plate (15), a right support plate (16) and a rear support plate (17) is mounted on the side of the mechanism receiving part (12a). The right support plate (16) supports the vibration absorbers (8) in a manner of being located below the wing part (12b). The casing (5) is mounted on the holding pedestal (7) in a shakable way via a coil spring (18). At the position where the casing (5) moves in both front and back directions, a left shaking restriction part (7e) is abutted to a first shaking restriction sheet (15c) or a second shaking restriction sheet (15d), thus restricting the shaking of the casing.

Description

technical field [0001] The present invention relates to an optical disc device for reproducing and recording information recorded on an optical disc by an optical pickup. Background technique [0002] An optical disc device that uses an optical disc such as a CD-R or DVD as a storage medium is equipped with a spindle motor that rotates the optical disc at high speed and irradiates laser light to the optical disc while moving in the radial direction of the optical disc to record data or receive laser light reflected from the optical disc to read data. out of the optical pickup. [0003] When the optical disc device is mounted on a vehicle, there is a problem that the optical pickup cannot record and read data due to external vibrations. As a technique for absorbing vibration, there is a technique that uses a vibration damper (for example, refer to Patent Document 1), and a technique for absorbing vibration of an optical disc device using a damper is proposed (for example, re...
