ABSTRACT:
A polishing apparatus has a spindle disposed rotatably through an opening of a base plate, a pair of side walls attached to the spindle, a compression roller attached rotatably to an end part of and between the side walls for compressing a polishing tape onto a target object, a tape-supplying roller and a take-up roller which are both attached rotatably between and to the side walls between the spindle and the compression roller, and a tape-running roller attached rotatably between and to the side walls for causing the polishing tape to travel. The axis of rotation of the compression roller intersects that of the spindle perpendicularly and both the tape-supplying and take-up rollers are parallel to the compression roller and their axes of rotation intersect that of the spindle such that the center of gravity of the apparatus is always on the axis of rotation of the spindle. The center part of the compression roller has a smaller diameter than the end parts which sandwich it so as to prevent the polishing tape from becoming twisted or wrinkled.
