Abstract:
A spindle motor inclination angle adjusting mechanism in an optical disk apparatus including a spindle motor with a rotary shaft carrying a turntable thereon, a chassis supporting said spindle motor thereon, and an optical pickup disposed on said chassis transferably so that an optical axis of said optical pickup can be moved in a direction substantially perpendicular to said rotary shaft of said spindle motor, to adjust inclination of said spindle motor relative to said chassis, said adjusting mechanism comprising:a tilt movement mechanism to support said spindle motor on said chassis tiltably both in a direction around a first tilt movement axis extending in a direction perpendicular to said rotary shaft of said spindle motor and perpendicular to a direction of movement of said optical axis of said optical pickup and in a direction around a second tilt movement axis extending in a direction of movement of said optical axis of said optical pickup and being perpendicular to said rotary shaft of said spindle motor, said first and second tilt movement axes intersecting in the rotary shaft, said tilt movement mechanism including a motor base to support said spindle motor tiltably in the direction around the second tilt movement axis, and said motor base being supported on said chassis tiltably in the direction around the first tilt movement axis; a first adjusting section to adjust the inclination angle in the direction around the first tilt movement axis by driving said spindle motor in the direction around the first tilt movement axis, wherein said first adjusting section includes a first urging means to urge said spindle motor around said first tilt movement axis, said first urging means being disposed such that its longitudinal axis is substantially perpendicular to the rotary shaft; and a second adjusting section to adjust the inclination angle in the direction around the second tilt movement axis by driving said spindle motor in the direction around the second tilt movement axis, wherein said second adjusting section includes a second urging means to urge said spindle motor around said second tilt movement axis, said second urging means being disposed such that its longitudinal axis is substantially perpendicular to the rotary shaft.
