2-3. Operation of slide base with skew motor
The purpose of this operation is to ensure that the detecting beam of optical pick-up block always
makes a right angle with disc. When the skew sensor detects the inclination, the skew motor
starts running to eliminate the inclination.
Skew motor rotates in the direction of arrow mark.
Skew gear rotates in the direction of arrow mark to 
rotate the skew cam in the direction of arrow mark.
When skew cam rotates, the slide base is tilted in 
the direction of arrow mark      centering around 
the fulcrum      .
Skew sensor detects the inclination, and skew motor 
stops.
* The rotating direction of the skew motor varies with
   the direction of inclination.
* Skew gear retainer holds slide base so that it
  always touches the skew cam.
