The relationship between the engagement shoe and the
platter gear comes to a state shown in Fig. 12. In this
condition, during the time in which the pitch of the grooves
is small, the movement of the engagement shoe is sinall.
The engagement shoe is thus pushed back by the nose of
the engagement shoe, the main gear being still.
When the stylus comes into the lead-out groove having a
large pitch at the end of a record, the movement of the
engagement shoe becomes larger than the reverse Movement
caused by the projection nose, entering the state which is
shown in Fig. 13,. where the projection presses the
engagement shoe to cause the main gear to rotate.
