II - DIFFERENCES BETWEEN MODELS

This review includes 100. 200. find 300 Series Cameras.

A.
SIMILARITIES
-
t. The
mechanical operations previously explain
ed
apply generally to all the shutters with slight
differences
to be
herein described. Because the
-
Model 362 Shutter
is
the original, and all others
are variations and improvements. on that shut
ter. the previous discussion in Section
J,
is basic
ally. a fu11 treatment of the Mode1362 Shutter.

If
more precise and detailed mechanical action
knowledge (assembly and disassembly) is de
sired, refer to the Repair Manual on Automatic

Shutters, Models 362, 366 and 374, published
May 1965.

DIFFERENCES
I.
From I"e Model 362 to the Mode13S9 Shutters
-
the main difference
is not mechanical. it is elec
trical. The mode1385 Shutter is fully explain
ed
in the Model 360 Camera Repair Manual, so
-
it
will not be considered in these instructions.
By virtue of changing.. and adding or subtl'3cting
components, the integral Electronic Modules,
have been refined so that approximately six
teen
(16)
varieties now exist. The variations
-
for the most part are minor. bUt the physical
pIacement of components on the board, the
size and number, the identifyIng color codes.
and the different flexible circuit solder points.,
-
are
possible problem factors.. The changes were
occasioned by other changes in the cameras
themselves: $Uch
as:
adding an electronic timer.
etc.
2.
To provide an answer for this problem and to
-
make
it
possible to substitute one module for
any or all of the others. is the purpose of this
manual. The method to be followed is: an ex
-
haustive deve!opment of all significant infonna~
tion about tne modules: an arbitrary number
jng to be applied
as a
positive means of Type
identification. and separation; and. finally, pre
cise directions as how to economically convert
from one type to anotber. wbere interchange
ability is simple and feasible.

3. The Table, Fig. 2-1. shown on opposile page,
is a compilation of the information presently
available on aU electronic modules now, or
previously used, on the automatic shutters for
pack cameras.
The remarks column briefly describes tbe
changes made. The text develops the differences
in more detail, and will indicate which modules
are
interchangeable and
what~
if anything, has
to be done to them) to substitute one type for
another.
