llluminotion
Successful copying requires perfecily even illuminotion of the subiect. The
four-lomp illuminotion orrongement provides the most suitoble lighting set-up
for this purpose. In its stondord position this ensures on evenly  lit subject
field. Generolly (e. S. for document copying) this stondord position should
noi be oltered.
The stondord set-up for the four-lomp illuminotion orrongement for uniform
ilf uminoiion of subject oreos up to 17 x 23 in. is os follows (see Fig. 3)  :
The clomps corrying the cross bors ore pushed os for os ihey will go ogoinst
ihe stop neor the fop of the verticol columns. The reflectors ore set ot right
ongles to the corrying orms which in turn ore set ot 45' to the verticol
columns. The reflectors ore thus fixed obout 4 inches obliquely obove the
electric plugs.
                               The reflectors ore left in  this

    The Focusing Stoge
     The focusing stoge (Fig. 6) moves to ond fro between lwo siops. One of the

     stop is fully pulled bock (l) the slide con be pulled our of the guide roils
     to the left for cleoning etc, In the middle position (2) the stop limits the
      lrovel of the stoge to ihe left in normol use. Pushing the stop forword (3)
      locks the focusing stoge.

When the Leico body (without lens) is fitted to ihe top of the focusing stoge
the lens mount must. fit correctly into the corresponding opening in the slide.
The comero is held by o spring clomp ond must be porollel to the focusing
stoge.
The correct position is fixed once ond for oll for the Leico model in use
(older Leico bodies differ somewhot in their dimensions) by meons of o
movoble stop (Fig. 5). The milled knob A ollows odiustment for the length
of the comero body, ond the smoll screw B neor it for the height.
To roise or lower the corrying orm, the locking screw is loosened  first. The
comero is focused by turning the lorge helicol focusing mount. For lorge
close-ups (r/e reduction to 2 x mognificotion) the detochoble fine focusing
odiustment should be used to roise or lower the corrying orm.

              opening up or stopping down, fhe slip-on diophrogm ring VALOO is fitted
             over the lens mount. The notch in the ring should fit over the operture
                setting pin of ihe lens when both ore set to f/3.5. The lens is then inserted
              in the boyonet mount of the lorge helicol focusing mount (Fig.7; tor
                 cloriiy the diophrogm ring hos been omitted in the illustrotion).

             dure for copying flot subiects is os follows:
                         '1. Switch on the proiector lomp or the lighting units by plugging the moster
               plug into the moins socket. Switch over lo the lighting unit with the
                 chonge-over swiich ot the left hond edge of the boseboord. This disconnects
                the proiection lomp. The ground gloss screen with the proiection heod on
                           it should be obove the lens.

 For occurote focusing o 5x direct or right-ongle focusing mognifier  is ovoil-
 oble. The right-ongle mognifier is only used for lorger solid obiects to ollow
 convenient viewing from the front of greoi obiect distonces.
 For Llz scole to full-size reproductions, or for  'l to l                                                                   Llz x ond I tl, to 2 x

to toke books ond similor moteriol up to 5 in. thick. While one holf of the
book is pressed ogoinst the plote gloss sheet, on odiustoble orm prevents
the other holf from flopping down. The froming'box is fixed ond correctly
oligned on the boseboord by o speciol locking device.
With books ond periodicols up to 81/r x 113/s in., two focing poges con be
copied simultoneously. ln this cose the book sloge compensotes for ony
difference in thickness of the two holves of the book. This book stoge evenly
presses both poges ogoinst the gloss plote.
To copy tronsporent originols, on illuminoting box is used (Fig.8). The
originol is ploced on the opol gloss sheet ond, if necessory, held flot by o
second sheet of gloss. The illuminciting box uses moins-operoted lomps ond
con be connected either to the socket in the boseboord, or direct to
the moins.
For photomicrogrophy  the micro-odoptor  is screwed to the focusing stoge
in ploce of the lens (Fig. 9). To odiust the focusing telescope for viewing
from the front, the locking ring obove the shutter cosing is turned onti-
clockwise to loosen it, ond pulled tight ogoin when the focusing telescope
is correctly oligned. The light screening tube should slide up to the index
line into o similor screening odoptor on the microscope tube. The height
of the corrying or:m with ttre focusing stoge ond micro-odopior is odiusted

At low mognificotions the microscope imoge is focused directly on ihe ground
gloss screen of the focusing stoge; with higher power obiectives the focusing
telescope.is used.
