The present invention relates to an optical disc drive and a feeding base. According to an embodiment of the present invention, a feeding base is coupled to a spindle motor base having a spindle motor mounted thereon to rotate an optical disc, is coupled to a stepping motor base having a stepping motor mounted thereon to move an optical pickup internally or externally, and has a main shaft and a sub-shaft mounted thereon to guide the optical pickup to move internally or externally. The center of the feeding base corresponding to a space in which the optical pickup moves is formed of a steel plate having an empty rectangular rim shape, and can includes two guides for guiding the coupling position of the spindle motor base. One of the two guides has a side section including an inclined section corresponding to a cone and a linear section corresponding to a cylinder which is formed of the steel plate protruding. The other can be formed of a portion of the steel plate bent. Further, the sub-shaft can be formed by machining a portion of the steel plate having the rectangular rim shape in bending form. Therefore, the price competitiveness of the optical disc drive can be secured by using the minimum number of components without using a separate component with the simplest structure, and the feeding base can be constructed only by press working an SECC steel plate, and in the mass production process of the feeding base, the distribution of dimensional variations of an important function part can be reduced to thus facilitate quality management. |
