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.

I

When skew cam rotates, the slide base is tilted in the direction of arrow mark @centering around

the fulcrum

@.

I

Skew sensor detects the inclination, and skew motor stops.

I

l

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.
