Abstract
An object of the present invention is to perform a pickup feed operation and a turntable raising/lowering operation by the use of a rotatable drive source mechanism () for rotatably driving an optical disk including, for example, a CD while avoiding interference between an optical pickup () and the same drive source () in an optical disk device () for recording and reproducing a signal on the optical disk. To accomplish the above-mentioned object, a dual-purpose drive source mechanism () generates a driving force for a pickup drive mechanism () and a turntable raising/lowering mechanism (). The operation of switching a transmission path of the driving force of the dual-purpose drive source mechanism () from a path leading to the pickup drive mechanism () to a path leading to the turntable raising/lowering mechanism (), or vice versa is performed by an operation independent of the optical pickup () under the driving force of the dual-purpose drive source mechanism ().
