ABSTRACT:
An optical disc apparatus includes, as a raising/lowering mechanism for moving a second base constituting a unit mechanism portion pivotally about a fulcrum so as to raise or lower the second base with respect to a first base as a base of the optical disc apparatus, a cam mechanism which is provided pivotably on the first base side within an orthographic projection area of the optical disc that is in a chucked state and which has a cam surface formed around and in the direction of a pivot shaft. In addition, a cam pin provided on the second base side is brought into engagement with the cam surface. When the optical disc inserted into the optical disc apparatus is chucked onto a turntable so as to be rotatable, the cam mechanism is pivoted about the pivot shaft by a cam drive section.
