When looking: through the rangefmder eye window

(when the camera is

out

of

focus). two images are

seen in the small

amber

or purple square. (In some

cameras. this may

be

a circie.) These images resull

from the ability

of

the bearnsr!itter

to

have iight

transmitted through

il

ing light reflected from it. This

pro

pert)' aUows

the viewer

to

observe one image superimposed

upon .mother image.

The

bearnspHtter also has

dichroic characteristics which

impart

color

to

the

image. One

of

these jmages.,

the

comes directly from the left rangefinder

window and is

transmitted

which indicates

that

Thls

is

accomplished

by

the

revolution

of

the

large~tooth

gear

as

it brushes past

the

cutout

on

the wheel,

It

strikes the

whed

producing a

-

''wltirringn sound,

The

second purpose

of

the

gears is

to

proVide a means by w hleb

the

timer

-

can

be

stopped.

Note

that

the

start

button

is

connected

to

a Ie\'er. Moving

the

button

to

the

right (as viewed from outside

the

camera) causes

the lever

to

engage

the

large-toothed gear. This

-

stops

the

gears which. in

tum,

stops

the

main~

spring,

-

The

post

on

the timing ring Slops

the

arrow and

thus determines how long

the

mainspring will be

permitted

to unwind. In Figure 2-12, you can

see

that

the

liming nng can be pushed in toward

-

the

lens since

it

is held in place

by

case springs

mounted

on

the interior housing.

By

pushing

the

timing ring in.

the

serrated base

is

released from

-

the

metal

stop on

the

door

case.

The

timing

ring

can

then

be turned. Since the unwinding

of

the

mainspring through

the

gears is

at

a

set

rate,

the

arrow speed is conslanL

Therefore,

timing can

be

established

by

allOWing

the

arrow

to

move

-

through

an

arc which can be related

to

time.

For

example,

if

the dial is pushed

in

and set so Ihat

-

"60"

is

under

the

red

dot,

the

arrow will move

from

the

"60"

until

it

hits
