release.
1) Charging operation (™@)) of self-timer causes self
start lever B, stopped by drive gear pin, to rotate
to the =>(2),
When self start lever B is rotated, release control
lever rototes to the ™() irrespective of shutter
dial position.

Accordingly, lowering of release plate becomes
possible over the entire stroke (2.6mm).
Anchor retainer, stopped by self start lever B,
rotates to the ®@) to retain the anchor thus prevent-
ing its operation during self gear charging.

@ Anchor retaining is completed when self-timer is
turned up to 16°30’.
SW. 5 is turned ON when release plate is lowered
0.4mm by pushing shutter button.

When self gear is started, drive gear returns to
the © and self start lever B is rotated to the
=@ by drive gear pin. Then release control lever
is set free to the *(@) causing main SW. holder
to be released, and then SW. 3 is turned ON.
@ When shutter dial position is at X, 1~1000,

4-5. Magnetic release by remote cord
When remote cord is connected to shutter button mechanism as
illustrated, release core, release button core and remote-control
contact are electrically connected to each other. Also, release
switch (S3) is connected in parallel to remote cord switch
(Sy). Then turning on S’; causes the magnetic release of
camera to operate.
@ At that time, release plate doesn’t operate.
holder is not operated and indication is not lighted.
However, indication will be lighted if the operation mode
is before- winding.
© Because release plate is not operated, when shutter speed
dial is at B, shutter’s bulb control doesn’t work, and shutter
operates at 1/100 sec.
So, main SW.
