Abstract
Disclosed herein are an optical disc drive and a feeding base. The feeding base is coupled to a spindle motor base and a stepping motor base. Main and sub-shafts for guiding inner and outer circumferential movements of an optical pickup unit are mounted on the feed base. The feeding base is made of a steel plate of a rectangular rim shape having an empty center corresponding to a space in which the optical pickup unit moves, the feeding base includes two guides for guiding the coupling location of the spindle motor base, and at least one guide of the two guides is formed by protruding the steel plate to form a funnel shape such that the side cross section of the at least one guide may have a slope section corresponding to a cone and a straight-line section corresponding to a cylinder.
Claims11
A feeding base of an optical disc drive, which is coupled to a spindle motor base on which a spindle motor for rotating an optical disc has been mounted, which is coupled to a stepping motor base on which a stepping motor for moving an optical pickup unit in inner and outer circumferential directions has been mounted, and on which a main shaft and a sub-shaft for guiding the inner and outer circumferential movements of the optical pickup unit are mounted,
- wherein the feeding base is made of a steel plate of a rectangular rim shape having an empty center corresponding to a space in which the optical pickup unit moves,
- wherein the feeding base comprises two guides for guiding a coupling location of the spindle motor base, and
- wherein at least first guide of the two guides is formed by protruding the steel plate to form a funnel shape such that a side cross section of the at least first guide has a slope section corresponding to a cone and a straight-line section corresponding to a cylinder.
An optical disc drive, comprising:
- a spindle motor base on which a spindle motor for rotating an optical disc has been mounted;
- an optical pickup unit for recording data on the optical disc or playing back data recorded on the optical disc;
- a stepping motor base on which a stepping motor for moving the optical pickup unit in inner and outer circumferential directions has been mounted;
- a main shaft and sub-shaft for guiding the inner and outer circumferential movements of the optical pickup unit;
- and
- a feeding base on which the spindle motor base, the stepping motor base, the main shaft, and the sub-shaft are mounted, for providing a moving space of the optical pickup unit,
- wherein the feeding base is made of a steel plate of a rectangular rim shape having an empty center corresponding to a space in which the optical pickup unit moves,
- wherein the feeding base comprises two guides for guiding a coupling location of the spindle motor base, and
- wherein at least first guide of the two guides is formed by protruding the steel plate to form a funnel shape such that a side cross section of the at least first guide has a slope section corresponding to a cone and a straight-line section corresponding to a cylinder.
