MOVISCOP FOR 16 mm CINEFILM
ZEISS IKON AG STUTTGART

I·
GENERAL INSTRUCTIONS:
The MOVISCOP is equipped with an optical balance
that scans the individual frames
of the film which runs
with uniform velocity. This balance consists
of a
rotating glass-prism
built into a drum shutter driven by
the film's perforation.
Focusing is done with a milled
screw below the cutter
on the front side of the apparatus. The film can be
marked
by the cutter where desired. By a slight
pressure on the
cutter the frame visible in the image
field can be marked with a minute incision.
The
MOVISCOP may be connected to the A. C. mains
supply after being properly adjusted to the voltage pre-
vailing. This
is done by adjusting the voltage control at
the right-hand side
of the casing, fitting 110, 125, 150,
220
or 240 volts. When delivered the MOVISCOP is
always adjusted to 220 volts!
The
projector lamp below the light house with the
optical lighting equipment
of the MOVISCOP is switched
on with the tumbler switch on the right side
of the
MOVISCOP housing.
The rewinders are screwed to a base board to which
the
MOVISCOP 16 can be fitted. Attention should be

paid to the fact that the rubber · footings of the
MOVISCOP 16 must touch the rear of the oblong holes
in the base board so that the apparatus is perfectly
adjusted to the rewinders. The MOV I SCOP can al so
be firmly attached to the base board by means of the
screws that are supp li ed in a bag. Fig. 4 s how s the
holes that have to be used for the MOVISCOP 16.
Before fastening the MOVISCOP, the sc rews in its
rubber feet have
to be removed.
Th e t wo rewinders have different transmissions. The
right-hand transmission
for forward winding, from left
to right, is so geared that films to be viewed and
edited can be run at the regular
projector speed. The
lefthand tr ans mi ssion, how ever , is geared for high-
speed rewinding. The rewinders are
equipped with
adjustable friction, tightening the film and pressing it
on the
MOVISCOP film track a ft er it h as run over two
film guide rollers. The spools rotate in the same
direction as that in which the rewinder cranks are turned.

THE VOLTAGE CO NTROL
In order to adjust th e MOVI SCOP to another vo ltage
than 220
volts unscrew the screw-cap (1 6) on the
vo lt age control (1 5). Un sc r ew it completely, including
the
built-in fuse, and loosen the sc r ew in the middle.
Th en rotate the black disk until the voltage setting
co rr esponding to the mains voltage is visible in the
c
ut -o ut of the disk. (If in doubt, read off the correc t
voltage from the meter). Sc r ew back the sc rew-cap
with fuse and fasten the
screw in the middle. The
MOVI SCOP is then ready for use. A micr o-f use for
0. 3 amps 5 x 20 mm sh ou ld be used for all voltages.
This fuse also protects the app
li ance from damage if
it is unintentiona lly connected to D.C.
SOURCE OF LIGHT AND CONDENSER
(Fig. 2)
Th e miniat ur e c in e lamp 25 vo lt s 1 amp with A.S.S.C.-
ca p (Osram No. 8203 or Philips No. 392 N) burns in a
h
or izontal position above the condenser (1 2) in such a
way that the film-gate i.n the film track (1 3) is uniformly
illuminated.
The bulb
ca n be conventiently exchanged when the two
fillister-head screws (7) are loosened and the light
house (6) is removed.
The exchange
of the bulb is very simple. Up on slightly
pr essing the bulb into the socket (14) and simultane-
ously turning it to the left by 90° it disengages from
6

the bayonet socket and can be removed. The new bulb
is fitted into the bayonet socket by a s light pressure in
the
direction of the socket and a 900 turn to the right.
When the bu lb is properly inserted the picture frame
of the film track should be evenly illuminated.
The condens or (12) below the bulb has a heat-filter ab-
sorbing some 70 % of the heat emanating from the bulb
without any loss of light intensity. Consequent ly, any
frame
of the film can be studied at l engt h without
suffering from the heat of the bulb.
HOW TO MARK THE FILM
When the knob (4) is slightly pressed by the thumb,
the
cutter makes a 1 mm incision into the film. This
incision can be detected later when running the film
through the hand between thumb and index finger.
THE FILM T RAe K, V lEW I N G AND ED I TI NG
For projecting cine film, fit the spoo l with the film to
be edited on the
winder (1) and bolt it. If the film is to
be
projected normally, i. e. if a positive image is to be
rendered on the
viewing lens, the beginning of the film
must be on the lower side of the feeding spoo l and
the
perforation must be on the side of the apparatus
(when 16
mm sound film is to be edited). Prior to the
projection and editing of the film adapt the friction (11)
of the l eft winder so that the pull of the right winder
7

s uffi c iently tightens the film and prevents fluttering
when it is running over the vaulted film track (13).
Th e film must be so inserted i nt o the appa ratus that it
runs (
5) around the low er side of the film guide rollers.
The beginning of the film is in serted and fastened to
th e right rewinder as usual.
After sw itching on the lamp with the tumbler sw itch (9),
th e proje cted picture ca n be focused with the focusing
knob (3).
Th e right rewinder (2) is so geared that the film runs
alm
ost at the normal projector speed.
REWINDING
Wh en the film has been viewed, c ut , and titled, it
Olust be rewound before it can again be projected .
This can be done in
tw o ways:
a) R
ew inding through the a ppar a tu s. In doing so, the
film must be taken out of the l ef t film guide roller
(5) and mu st be run over it to reduce wear and
t
ea r. When the film is run through the apparatus
in this ma
nn er the -perf orat ion does not engage
with the tr an spo rt mechanism and the e ntir e apparatus
is
out of gear (Fig. 5). It is also ndvi sab le to sw itch
off the lamp.
b) R ew inding without the apparat us which is, therefore,
re mov ed backward from the oblo ng hole s in the
base board.

Rewinding
I----- - --~ Q '-- - ----------i
Fig. 5
In rewinding with or without the apparat us care s hould
be taken that the end of the fi lm is led around the
lower side of the spool core when it is in ser ted into
the l eft spoo l. The spoo l must be wound cl ockw ise,
otherwise the film cann ot be projected normally.
The l eft r ewinder is especia lly geared for highspeed
rewinding.
Before rewinding the film, loosen the friction of the l eft
rewinder (11) while applying some friction to the right
one, so that the film does not come off the right-hand
spoo l s hould the rewinding be slo wed down or sudden ly
stopped .

I,
CARE AND MAINTENANCE
The film track should always be absolutely clean to
prevent scratching of the film. Small dust particles in
the picture frame must be removed with a small hair-
brush, because they might be very annoying in the
editing process
if projected on the image field lens
with tenfold or twentyfold magnification.
The prism
of the optical adapter must be carefully
cleaned from time to time with a soft hair -brush. The
prism can be seen behind the picture frame on the
film track when the light house is removed.
The rewinders must
be regularly lubricated through the
oil holes.
Subject to alterations in the interests of technical
progress.
M 0 V I S
COP 16 with film pressure pad
In addition to the components described in the instruc-
tion manual, this
editor is now equipped with a film
pressure pad, for the purpose of preventing the image
from
drifting in and out of focus as the film passes
over the curved film track. When threading the film,
the plate of the pressure pad (which projects forwards
over the film track) must therefore be raised slightly.
