A pickup supportersupporting a pickup deviceA includes a driverhaving an abutting surfacethat is a flat surface substantially in parallel to an axial direction of a lead screwand intersecting with both a focus direction and a plane direction substantially vertical to the focus direction. With such arrangement, even when a posture of the pickup supporteris changed by adjusting heights of the main shaftA and the sub shaftB, the screw abutting surfacecan abut on the lead screwat a substantially constant angle. Therefore, when the posture of the pickup supporteris changed, substantially constant driving force can be transmitted from the lead screw, so that stable and proper driving force can be constantly obtained.

A frame bodydisposed within a case bodyis provided with a main-body portionfor rotating an optical diskto thereby read recorded information therefrom. The frame bodyis assembled with a cooling fan. The frame bodyis provided with a duct part communicated with a suction side of the cooling fan. The frame bodyis mounted with a circuit boardfor closing a lower surface of the frame bodyand covering the below of the main-body portion, to thereby define a machine room and an airflow path room within the case body. The circuit boardis formed with a through-hole. Fresh air is allowed to efficiently contact with electrical components to thereby cool them.
