Abstract
The heat dissipation of a pickup is improved in an optical disc apparatus of a slot-in type. A unit coveron a disc-facing side of a unit mechanismincludes a circumferential plate, a lever supporting plate, a disc guiding plate, a flexible printed circuit board holding plate, a reinforcing plate, a driving part covering plate, ventilating openings near sub guiding shaft, an extended notch near sub guiding shaft, an outer extended notch, and an extended notch near main guiding shaft. With this configuration, plenty of air flow induced by the rotation of a disccan be introduced to a pickupalso through the unit cover, greatly improving heat dissipation capability.
