Abstract

The invention relates to a guidance axis height regulating mechanism and a CD device which are easy to assemble and cheap to manufactured. A guide shaft height adjustment mechanism (8) includes an adjustment member (81) rotatably provided on a plate-shape chassis (43), and provided at the vicinity of an end of a guide shaft (77) for guiding an optical pick-up along a radial direction of an optical disc. The adjustment member (81) has a contact surface (815) which is contact with the guide shaft (77) from a side opposite to the chassis (43), the contact surface (815) is slanted to the chassis (43) while being formed in a circumference direction of the adjustment member (81), the guide shaft (77) is press-contacted with the contact surface (815) by using a push-pressure of a roll spring (82). The adjustment member (81) is formed to a direction far away from the chassis (43). The heights of the guide shaft (77) and the chassis (43) are capable of being adjusted by rotating the adjustment member (81).

Description

technical field [0001] The invention relates to a guide shaft height adjustment mechanism and an optical disc device. Background technique [0002] Optical disc devices for reproducing or recording / reproducing optical discs such as CD-ROMs, CD-Rs, and DVDs are known. Such an optical disc device has a box-shaped device main body and a movable disc tray that moves an optical disc to a loading position and an ejecting position relative to the device main body. In addition, on the bottom plate provided in the main body of the device, an optical disc rotation drive mechanism for rotating the optical disc, an optical pickup (optical head), and an optical pickup moving mechanism for moving the optical pickup in the radial direction of the optical disc are respectively provided. [0003] The optical pickup moving mechanism has a guide shaft for guiding the optical pickup in the radial direction of the optical disk, and the laser light emitted by the optical pickup must be adjusted ...
