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
mechanism assembly.
3) Remove the soldering from the MC-1 PWB assembly,
then remove the photo diodes
. When removing the photo diode
top sensor side, refer to section 3-15 and remove the
main cam.
ASSEMBLY NOTES:
1. Fit the photo diodes
receptors to face the LED
Align the cuts in the LED
Push the photo diodes
down as they will go, so that they do not protrude
above the top of their holders.
2. Do the soldering quickly.
