Adjustment of winding torque
In normal
forwarding,
(especially
when
the recorder unit
is in upright or suspended position) and when the recording
tape slackens or
when
the recording
tape
on
takeup reel is
loosely
wound,
adjustment
of
the
following
tension
is
necessary :
~ String
Over than 60g
Tension Gauge
As shown
in the illustraion,
loaded
reel
is placed
on
the
spindle and the mechanism
is put into FWD.
Using tension
gauge, the reel is pulled in the
direction
of arrow,
and the
strength
at
the
instant
when
the
reel rotates
in
anti-
clockwise
direction
is determined.
Bend Lever (21) to make
the adjustment.
After adjust-
ment, make
sure this lever and leaf spring does not contact.

In Rapid Fowarding
(Winding)
In rapid winding, the entire length of recording tape must
be transported at
fast speed.
To adjust
the strength,
the
method
is exactly
the
same as
in
the
case
of
Normal
Forwarding
Para.

"Adjustment
of

torque".
The reading of strength must be identical.
In Rewinding
In rewinding,
as
in the
instance
of rapid
winding,
the
entire
length
of recording
tape
must
be
transported.
At
times, the spring
(23) may
be weak, or eyelet part (24) may
be tight.
Examine
these
points, and rewind the tape which
has already
been
rewound.
If the
machine
functions,
the
adjustmeut is complete.

Then
smoothen
the surface and apply grease.
In additton, when peculiar noise
or sound
is produced
by
mechanism,
adjustment or repair is necessary.
Supply Reel Ease (Spindle)
At stand still, the supply
reel base
must
not
move
more
than
0.2 — 0.4mm
in
vertical
direction.
Adjustment
is
done
by
changing
the
thickness
of
nylon
wahser
at
the
upper part of the reel base.
Pinch Roller
The
pinch
roller must
not
move
more
than
05mm
in
vertical
direction.
STORAGE
After using the tape recorder,
make
sure
all the push
buttons
are in raised "stop" position, then close the lid.
To store the tape recorder for an extended
period, take out the
batteries. When
kept too long, the butteries may
leak
and
damage
the mechanism.
LUBRICATION
This
tape
recorder
requires
little oiling,
and
besides,
rotating
shafts are equipped
with oil reservoir device.
Do not put too much
oil as excess oil may
flow or
rise on the
shafts and adhere
to belt or pinch roller or other rubber parts and
cause slipping.
