Abstract:
1. An optical disc apparatus for performing write or read of information in a changed state of a height position of a disc plane after chucking of an optical disc onto a turntable, said optical disc apparatus comprising: a first base which serves as a base of said optical disc apparatus; a second base which is pivotable about a fulcrum with respect to said first base, and on which a disc motor for driving said turntable rotationally is mounted; a cam mechanism which is provided pivotably on said first base side, and has a cam surface formed around a pivot shaft which extends in substantially the same direction as a rotary shaft of said disc motor; a cam pin which is provided on said second base side and engages the cam surface of said cam mechanism; a cam drive section which drives said cam mechanism rotationally; and position restricting component which restricts the position of said cam pin in the disc plane direction when said second base is at a first height position for write or read of information to or from said optical disc and cancels the position restriction of said cam pin in the disc plane direction when said second base is at a second height position which corresponds to a chucked position of said optical disc onto said turntable.
