As the operation described in 8) is performed, the
Head slider ass'y (37)
claw (t) of the reverse slider (46) lifts the L.H.
pinch roller fever ass'y (6B) to such a position that
the head slider ass'y (37) can lift the L.H. pinch
roller lever ass'y (6B). The other claw (s) lowers
the R.H. pinch roller lever (6A) to such a position
that the R.H. pinch roller cannot be lifted by the
head
slider ass'y (37). Thus, reverse operation
is
almost completed.
At this time (when t2 has passed since the iron core
of the solenoid ceased to be attracted), the holding
voltage e2V is applied to the solenoid (L2).
However, the solenoid (L2) is not attracted because

the voltage is still lower at this point.

lever (566) and depresses the iron core of the sole-
noid (L2). (See Fig. 7.)
Because holding voltage e2 is applied to the solenoid
(L2), the iron core is held and consequently the
