Rotate the pulse motor (main) in the a direction.  The planetary gear rotates in the a’ direction,
dislocating its position in the a” direction.  This causes the planetary gear to be separated from
gear A.  The hopping gear will not rotate.  The triple gear and transfer gear rotate via the idle
gear to drive the EP unit.
