when seJecting these procedures.
Section
VI is the parts identification section, It
contains parts lists and exploded view drawings
for
aU 100> 200, and 300 Hne cameras.

SECTION II - PRINCIPLES OF OPERATION
THE FILM PACK
A d~:o.t:ripfion of the Polaroid Land pack I..'ilmera
~hould beltin with an explanation of the operation
of tht> film p:u;k itself. The following description
1s Olpplk:able to both the black and white (Type
107) lind rhe color (Type t08) film pack.
Figure 2~1 is a cross-sectional representation of a
film pack looded in the camera.
The black safety
cover which normally surrounds the negative and
positive material has been removed. positioning
the first white tab in the number 4 slot of the
rear door assembly. The ejghl negatives. each
with its own pod of developing jelly. are held in
posifion by the spring~loaded pressure plate. On
the other side of the pressure plate is the stack of
eight positives. Both the negative and its corre-
sponding positive is joined by a paper leader to. it
yellow tab, In turn, the yeUo'>;V tab is cennected
to the white tab.
Pulling the white tab out ef the camera (after the
negative has been expos,ed) accomplishes two
thjn~ as shown in Figure 2~2. (To. simplify
matters, the illustration shows only one negative
and one positive.) First, it feeds the yellow tab
be1ween the rollers. and out the door. Second. it
pulls the exposed negative around the pressure
plate 50 it faces. the positive sheer. It should be

camera does not start picture development. It
simply places aU of the picture assembJy pans in
the proper position for the next step.
To develop the picture, the yellow tab is pulled
out ef the camera as shown in Figure 2-3. This
action bursts the pod on tbe negative. As the
negative and positive are drawn through the
rollers., an even coating of deveIopingjelly is
spread between the two. sheets- The picture then
develeps outside the camera.

spring workmg together, guarantee thar the neg-
Siitive being exposed is at tbe appropriate focaJ
plane.
The edge conlrol bar and slide block assembly
serve 'to funnel
the yellow tab through the
-rollers. The slide block acts
as a movable plat-
fonn
for the edge controJ bar whleh has both
-lateral
and vertical movement. The bent fingers
on the bar catch the tab and direct the film
through the roUefS in a straight Jine. (However.
they cannot fOtaUy prevent bad spreads caused
-by film being pulled
out of the camera at extreme
angles.)
The play in the edge control bar aJJows
the assembly to move with the tab and thus
avoids any ripping of mm, Note that the top
roner has a shoulder at either end. They provide
for a separation which pennits the tab to fit
through the rollers. When the rollers are freed
-for
cleaning, the sliding block moves the edge bar
back out of the way.

THE FOCUSING SYSTEM
Tltl.' I"ad .. C~nler.! focusing system is controlled by
the usc of the two focus buttons shown in Fig~
UTe :-6. The Jinkage. consisting ofltle focus bar
assembly. the inner frames and the U~frdme. holds
Ih.:
shutler housing assembly (containing the
lenses) in place.
When
the right focus button tS pushed~ the focus
bar assembly moves to the left and pulls the inner
frame with j1. The action of the Unkage dr4ws
the shutter assembly toward the camera body,
reducing the focal distance (lens-to-film diStance).
When
the left focus button is pushed, tile Jinkage
reacts in
the opposite manner and the shutter
housing is moved away from the camera body,
increasing
the focal distance.
The focusing linkage controlling lenNe-film dis-
tance is mechanicany coupled to the particular
type of rangefinder/viewfinder used on the
L"'3mera, A bracket on the focus bar is tied to a
pick~up cam in the rangefinder/viewfinder. The
movement of the cam adjusts the rangefinder/
viewfinder" When
the image is in proper focus
according
to the rangefinderjviewfinder (or when
the proper distance is shown in the rangefinder),
the lens is automatrcally set al the right foca!
distance.
On some cameras, II fasf focus decal is mounted
on the Jocus bar assembly. When the focus but~
Ions <lfC moved. the decaJ slides past an indicator
on the camera body. FiduciaJ marks on the decaJ
are lined up with the indicator to lJpproximate
distances from the ClJrnera to the subject.
LENSES
There are two types of lenses used in the pack
camera.
The following models use a two element
(duple!) molded plastic lens:
Model 104
Model'25
MOOeI210
Mod,I21S

RANGEFINDERS/VIEWFINDERS
-111t'rc are
Ihrt~c types of f.lIlgellnders/v1t'wfindefS
llscd in Polaroid
Land aU[om;.atil: pack cameras.
-The first.
is a relatively simple image slZ!!r which
frames the subject and provides a scale for cstj~
mation of distance between e:.lmera and subject.
The second model is a true rangdinderJview~
nnder which focuses by superimposing two
images of thl;' subject, Separate windows are pro~
vided for the focusing and fmming functions. The
-
-third
type js the Zeiss Ikon model which also
focuses
by superimposing two images. However.
both the focusing and framing images are viewed
-through a single
window.
Image Sizer
- The jma.ge sizer is used on the Model 104, 125.
115. 210,and 315 cameras. figure 2-7 shows the

For many shots. the second method can be used,
This requires that the subjects' face be framed

To do this. the fixed line is set a1 the lop of the

R:mgefinder
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 while simultaneouslY hav-
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
reOected image. One
of these jmages., the fixed
jma~, comes directly from the left rangefinder
window and is
transmitted through the beam*
splitter
to the eye window. The second image;
the movable image. is channeled through the right
rangefinder window to the movable image mirror
which reverses it. The image is reflected through

Mechanical Timer {Models 330 anu 340)
The mechanical timer is ii sprin~riven device
designed to mea5Ure elapsed time. Figure 2~IO
shows how the timer is set into the rear door
assembly. To help in understanding how the
timer works, think of it as being composed of
three parts: the starr button, the liming: ring. and
the spring-driven gear assembly.
FIG. 2.10 MECHANICAL TIMER
The fjrs:t step taken to operate the timer is to
Wind the arrow until it points to the red dot in
the snm button. Second, the timing ring is
pushed in and
then turned until the desired time
is 'iet under the red dot. Third, the start button
is: pushed to the left. What these operating pro~
cedures actually do can be explained by examin~
ing FigurL' 2·11.
When tilt' arrow
is turned, the mainspring inside
the timer i!l being wound. The action of (Jle
spring. while it
unwinds. drives rhe arrow around.
You can see (hat the spring IS also linked 10 a
"ene:.
of gean.. In addition to controlling the un·
winding of the mainspring. the purpose of the
gears 1s two-fold. One, they provide the sound

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 whleb 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 the plastic stop ilt "0",

Electronic Tjmer (Models 335, 350. and 360)
The electronic timer (Figure 2~ 13) measures
elapsed time
in frames of 15 seconds to J 20 sec~
onds. It does this by measuring the time it takes
to charge a
capacitor in the timing circuiL Be~
cause of the power requirements of the timer, a
second 3 volt
battery is needed in the camera
