Abstract:
An apparatus for at least reproducing information from a disk-shaped recording medium, said apparatus comprising:a driving member arranged movably in a first direction which is in parallel with an imaginary plane substantially in parallel with a surface of said disk-shaped recording medium, said driving member including an inclined portion which is inclined with respect to said first direction and a spatial portion formed by a first portion of said driving member and a second portion of said driving member, said first and second portions being separated from each other when viewed in a second direction which is perpendicular to said first direction;a movable member arranged to be movable in a direction toward said disk-shaped recording medium as well as in a direction away from said disk-shaped recording medium in accordance with a displacement about an imaginary straight line extending in parallel with said imaginary plane, said displacement being performed by a contact of a part of said movable member with said inclined portion of said driving member,a spindle motor secured to said movable member for rotating said disk-shaped recording medium,a turntable secured to a driving shaft of said spindle motor, said disk-shaped recording medium being supported by said turntable under such a condition that said movable member has been moved into a given position,a position detector for generating an output signal which is changed in accordance with a movement of said spatial portion of said driving member, said output signal being changed under a condition that said movable member has been moved into said given position.
