Abstract
A frame body 11 disposed within a case body 2 is provided with a main-body portion 20 for rotating an optical disk 28 to thereby read recorded information therefrom. The frame body 11 is assembled with a cooling fan 13. The frame body 11 is provided with a duct part communicated with a suction side of the cooling fan 13. The frame body 11 is mounted with a circuit board 81 for closing a lower surface of the frame body 11 and covering the below of the main-body portion 20, to thereby define a machine room and an airflow path room within the case body 2. The circuit board 81 is formed with a through-hole 83. Fresh air is allowed to efficiently contact with electrical components to thereby cool them.
