Abstract
The inventive reproducing and driving unit of a device for reproducing the data recorded in a disk record reduces the height and weight of the device and the power consumption for moving the turntable and pickup, and prevents the pickup from receiving excessive shock. The reproducing and driving unit comprises a support plate (1), a motor (2) fixedly arranged in the support plate, a turntable (4) axially moveable on the shaft (24) of the motor, and a common moveable link member (28) for reciprocally moving relative to the support plate (1) so as to cause the turntable (4) and pickup (5) to be taken nearer to and away from disk record (29).
