Polishing apparatus
First Claim
1. A polishing apparatus for advancing and rotating a polishing tape, said polishing machine comprising:
- a base plate having an opening therethrough;
a spindle rotatably contained in said opening through said base plate;
a first rotating means attached to said base plate for rotating said spindle;
a pair of side walls attached to said spindle;
a compression roller for pressing a polishing tape against a target object, said compression roller being rotatably attached between said side walls, said compression roller having a rotary shaft which is perpendicular to the axis of said spindle, said compression roller having a center part with a smaller diameter than end parts which sandwich said center part;
tape-advancing rollers including a supply roller and a take-up roller both having a rotary shaft which is parallel to the rotary shaft of said compression roller and rotatably supported by said side walls, said supply roller serving to supply said polishing tape and said take-up roller serving to take up said polishing tape supplied from said supply roller; and
a second rotating means attached to said spindle for rotating said take-up roller.

Abstract
A polishing apparatus, for polishing/cleaning a target object surface by using a polishing tape, has a spindle rotatably placed inside an opening formed in a base plate, a motor for rotating the spindle, a compression roller rotatably supported between a pair of side walls attached to the spindle, supply and take-up rollers supported rotatably by the side walls for advancing the polishing tape, and a motor for the take-up roller. The polishing tape is supplied from the supply roller and taken up by the take-up roller through the compression roller, while rotating around with the spindle. The compression roller has a smaller diameter at its center part than at its end parts for preventing the polishing tape from becoming twisted or wrinkled when the compression roller is rotated by the motion of the spindle while being pressed against a target object and being advanced from the supply roller to the take-up roller.
