MECHANISM DESCRIPTION
5.
FF
When the sub motor further rotates, the cam of the FR
plate (26) moves €) so that the FR arm (24) is rotated in
the reverse direction... @. Thus, a slot (FF hole) of the
FR plate (26) is detected by the mode sensor (PH3) to
stop the rotation of the sub motor.
6.
Change from FR plate to PRO plate
When
the sub motor further more
rotates, the knob of
the FR plate (26) hits against the knob of the PRO plate
(27) . . .
@® . so that the PRO plate (27) moves.
Thus, the rack of the PRO plate (27) enters into engage-
ment with the mode gear...
@ . Then, the rack of the
FR plate (26) is disengaged from the mode gear because
of its non-toothed
section
coming... @® . The
mode
plate spring (88) assists in this operation.
7.
FWD
PLAY
When the PRO plate (27) moves 25) , the takeup plate F
is rotated by the cam
of the PRO
plate (27) and the
takeup gear (44) engages with the reel assy (31)
B
:
The rotation of the flywheel (8) is transmitted to the reel
assy (31) by way of the takeup gear (44)... @ . Thus, a
slot (FWD hold) of the PRO plate (27) is detected by the
mode sensor (PH3) to stop the rotation of the sub motor.
PH3
The groove of the PRO plate (27) serves to advance the
head plate (805)... @®. to move the head and the pinch
roller (48) to their FWD
PLAY position. The pinch roller
(48) is contacted to the capstan (8) by pressure due to
the shift of the takeup plate and the force of the pinch
roller spring... @®
