The damper means consisting of the moving chip 84 and the coil 81 damping the straight line movement of the carriage 14 is provided, and the detection means providing the shutter 74 inserted between the light emitting element 78 and photodetectors 76, 77 detecting the up/down-operation of the tone arm 5 is provided.
