Product Description

Following is a sample of the information contained on this CD: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pickup device, and more particularly to a pickup device which is used for performing recording and reproducing operations on a DVD, a CD-ROM, an MD, or the like. 2. Description of the Related Art A pickup device of this kind comprises: a movable frame that holds a pickup; and a guide shaft that guides travelling of the movable frame in directions along which the movable frame approaches and separates from a disk table. Rotational motion of a travel driving motor is converted into linear motion of the movable frame by a pinion and rack mechanism or the like. Generally, the guide shaft is configured by a main shaft and a sub shaft which are attached to a support frame (chassis).

On the other hand, it is desired to configure a pickup device of the above-mentioned kind so that a beam output from a pickup perpendicularly impinges on a recording plane of a disk which is mounted on a disk table. In order to satisfy this request, tilt adjustment must be performed by a tilt adjusting mechanism. In one of means for performing tilt adjustment, end portions of the above-mentioned main and sub shafts are vertically moved with respect to the support frame to finely adjust the tilts of the shafts. As a tilt adjusting mechanism using such means, conventionally, known is a mechanism which is schematically shown in FIG. 6. The tilt adjusting mechanism of FIG. 6 has a
