4-2-4 Cable treatment within chassis
Since the reel motor Ass' y and LED hole sensor Ass' yare mounted on the
sliding parts, it is necessary to clamp each cable at the specified position
so that the cassette tape can always be loaded or unloaded normally.
When rep lacing the reel motor (F), (R) Ass' y or LED hole sensor Ass' y ,
perform cable treatment in the following procedure:
(1)
Push in the ej ector with the finger to set the main unit to the
cassete loading status (Fig. 302).
(2) Perform cable forming in accordance with Fig. 409.
(3)
Clamp the cables of the reel motor (R) Ass'y and LED hole sensor
Ass'y from the outside of the tube with the cable tie at the position
which is kept approx. 10
mID
away from the end of the tube.
At this time, place the LED hole sensor side tube as near to the
terminal part as possible.
(4) Clamp the individual cables of the encoder Ass'y, reel motor (F), (R)
Ass'y, and hole sensor Ass'y between the bead and solenoids stopper.
(5) Push the cables into the PCBA holder.
(6) Push the eject button to return to the cassette unloading status.
(7)
Repeat the cassette loading/unloading operation several times by
using the work cassette, and check for the following items:
(a) The reel motor is not to be lifted when the back of the reel motor
is pushed in cassette loading status.
(b) Any cable is not to be caught by sliding parts.
(c) Any cable is not to be protruded from the drive body.
Note Be very careful about the cable clamping, since such trouble
as disconnection or malfunction may occur if a cable is
stretched too tight.
