Light receiving element
receives light which has
passed the set-aperture
point. When mirror begins
rising, memory SW (S,)
operates to memorize the
information and transmits
it to speed control
circuit.

Mode selector switch is at

(Ss) operates irrespective
of the information of light
received by light receiving
element. Then the
resistance information of
set shutter speed is
transmitted to the speed
control circuit.
