3-18.TAPE SENSORS, REEL SENSOR
AND EP SW LEVER
3-18-1 TAPE TOP SENSOR AND TAPE END
SENSOR (See Fig. 3-18-1)
1) Refer to section 3-2 and remove the mechanism unit.
2) Refer to section 3-3-1 and remove the cassette mecha-
nism assembly.
3) Remove the soldering from the MC-1 PWB assembly,
then remove the photo diodes
1
,
2
and the LED
3
.
When removing the photo diode
2
on the tape top
sensor side, refer to section 3-15 and remove the main
cam.
ASSEMBLY NOTES:
1. Fit the photo diodes
1
and
2
so that their photorecep-
tors to face the LED
3
, as shown in Fig. 3-18-1. Align
the cuts in the LED
3
and the holder
4
.
Push the photo diodes
1
,
2
and the LED
3
as far
down as they will go, so that they do not protrude above
the top of their holders.
2. Do the soldering quickly.
Turn the photoreceptors to
face the LED

3-18-2. REEL SENSOR (See Fig. 3-18-2)
1) Refer to sections 3-12-2 and 3-12-4. then remove the
clutch mounting assembly, the T soft brake assembly
and the take up reel assembly.
2) Refer to section 3-13-2, then remove the wheel gear 2,
the wheel gear 1. and the brake control lever.
3) Remove the soldering from the MC-1 PWB assembly,
then remove the photo diode (reel sensor)
1
.
ASSEMBLY NOTES:
1. When assembling the parts, align the cut on the photo
diode (reel sensor)
1
with the protrusion on the
mechanism chassis
2
.
2. Do the soldering quickly.

1) Refer to section 3-3-1 and remove the cassette mecha-
nism assembly.
2) Remove the EP switch spring
1
.
3) Remove the clamp
2
, then remove the EP switch lever
3
.
ASSEMBLY NOTES:
1. Apply grease (VHJ-0100) to the protrusion
4
on the
back of the EP switch lever
3
.
2. After fitting the cassette mechanism assembly. check
that in EJECT mode. the EP switch lever
3
does not
touch the EP switch
