A. Replacement of Delayed shutter release
1) The arabic numeral in a circle as
shown in Fig. 61
indicates the procedure of disassembly
and reassembly is normally the reverse
of disassembly.
•·
Note : Please refer to "l-4" for replacement of its lever.

, 3 and 4 as shown in Fig. 62 .
he LS134 Tl Shutter rele~ bar
is depressed by the end of\!!j-SLS

C. Check
l) Releasing position of shutter :
While the SLT21531 Rel ease l ever moves
from 2mm to 3mm, the shutter should be
released.
2) After releasing, the~-SLT21531 Release
lever should move a ~tle move and should
re turn.
3) During operation of the Delayed shutter
r elease, its operating speed must not
change remarkably .

A. The exposure time control capacitor Cl discharges
1) With the film advance crank or knob wound,

B. Beginning of charge to Cl capacitor
1) When dep ressing the shutter r eleas e button,
the l st curtain runs and the shutter is

2) When the lst curtain moves , the SW2 Trigger
switch is off and then the exposure t ime

..
3) The charge- time of capacitor Cl i s determined
by VRl (Shutter speed).
C. Determining expo sure time :
1 ) When the capacitor Cl reaches the determined
voltage in VR2, the moving coil is moved by
I C.
(A )
2) Capacitor C2 discharges , energizing the movi ng Cl
coil which in turn moves the 2nd curtain runs
and the shu tter is closed.
D. Charge t o capacitor C2
1) With the 2nd cur tain cl osing, SWl main swi t ch
is off and t hen capacitor C2 charges.
2) The charge-time is extremely s hort and accomplished by ve ry lit tle elec tric power.
Battery performance is maintained a t a high
level , as indica t ed in the accomanying diagrams, as the moving coil cond enser is normally charged keeping the battery at peak
voltage.
Thus t he battery is protected from drops in
voltage, as when t he switch i s on.

As Germa diode has a special character that is to send
electric current only in one way direction,
if you insert ! poles of the Battery Upside-down,
the current is off.
If above check for the BC.lamp is 0 K, but the lamp
does not illuminate yet, change the BC.lamp to
new one .
