3.3.2.2 Shifting PG (APG Mechanism)
This product's APG Mechanism shifts PG with the APG Cam mounted on the Carriage.
APG Cam is located between the CR Guide Frame and the Carriage, and has a stepped
cam face. With the APG Lever applied, if the Carriage moves toward the APG Lever,
the lever pushes the APG Cam, and the cam face of the APG Cam in contact with the
APG Slider is shifted. This action shifts PG.
