PURPOSE:To eliminate the generation of the operating noise at cleaning and to simplify a structure by forming a cam lever and a driving lever in one body and using an elastic member for the lever, and absorbing the rotary motion of the lever when a recording disk is loaded. CONSTITUTION:One lever 51 functions as the cam lever and driving lever, and the lever 51 which is driven by a jacket 11 to rotate in a direction X8 is returned in a direction X7 by the repulsive force of flexure of its arms 1a and 2a. Therefore, the need for a tensile spring is eliminated and the number of parts is reduced. when the jacket 11 is drawn out, the lever 51 rotates in the direction X7 by the resiliency of flexure of the arms 1a and 2a to abut on a specifying part 6a, and a cleaning lever 38 having a reproducing stylus 36 on a cleaning pad 41 is rotated in a direction X3 to the position of a stopper 43 by a tensile spring 42, sweeping away dust on the reproducing stylus 36. Therefore, its operation precision is high. Further, the elastic deformation of the lever 51 is utilized, so the operation noise is made small. |
