Tape Sensors, Reel Sensor And Ep Sw Lever - Sony SLV-E105 Service Manual

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@®, @ and the LED
@. When removing the photo diode@® on the tape
top sensor side, refer to section 3-15 and remove the
main cam.
ASSEMBLY NOTES:
1. Fit the photo diodes @ and @ so that their photo-
receptors to face the LED @), as shown in Fig.3-18-1.
Align the cuts in the LED@®) and the holder @.
Push the photo diodes @, @ and the LED @ as far
down as they will go, so that they do not protrude
above the top of their holders.
2. Do the soldering quickly.
