Patent ID: 7043741

Claim:
An adjustment apparatus for regulating the inclination angle of a spindle motor of an optical disk drive, wherein said spindle motor is mounted on a driving circuit board which is mounted in a traverse module and has adjustable screws for regulating the inclination angle of said driving circuit board and said spindle motor; said adjustment apparatus comprising: an optic axis regulating tool for containing said traverse module and regulating said adjustable screws of said driving circuit board, wherein the top surface of said optic axis regulating tool has an opening to expose said spindle motor and a guide rail of said traverse module; a standard plate, placed in said opening and against on said guide rail, wherein the upper surface of said standard plate is in parallel with said guide rail; a comparable turning wheel, placed in said opening and covering said spindle motor, wherein the upper surface of said comparable turning wheel is in parallel with the rotation plane of said spindle motor and a plurality of turbine-like blades are set at the edge of said comparable turning wheel; a gaseous spray nozzle, mounted on the top surface of said optic axis regulating tool and facing the edge of said comparable turning wheel and spraying gas out toward said turbine-like blades to drive rotation of said comparable turning wheel and to simultaneously drive rotation of said spindle motor; and an autocollimator, emitting light beams respectively onto said standard plate and said comparable turning wheel and detecting the reflective light beams thereof to decide the inclination of said comparable turning wheel in relation with said standard plate; wherein an operator can regulate said adjustable screws on said driving circuit board through said optic axis regulating tool, based on the detecting results of said autocollimator so as to regulate the inclination angle of said spindle motor.
