1. GENERAL DESCRIPTI ON OF THE KONI- RAPID OMEGA
Outlined below are the mechanisms and subasse:nblies
incorporated in the KONI - Rapid Omega camera.
The KONI-Iiapid Omega consists of the following sub-
assemblies which can be removed:
Main body CQ~ponents
1) Lens mount (B3100)
2) Shutter release mechanism (83200)
3) Focusing mechanism (B3300)
4) Light barrier mechanism (B3500)
5) Shutter cocking mechanism (83600)
6) Rangefinder coupling mechanism (83800)
7) Camera body exterior (B3700)
8) Raneefinder base , viewfinder (RlOOO - - R5000)
Backlid canponents
1) Pressure plate side (M2000)
2) Film counter mechanism (M2000)
Lens Barr el components
1) Lens barrel mechanism
2) Lens- shutter mechanism
The KONI -Ra~id Omega is made up of five (5) die- cast
portions , as follows , into which the various mechanisms are
assembled :
1) Main body frame (83401) contains the focusing ,
shutter release and light barrier mechanisms . The
camera body exterior is attached after the r el ated
mechanisms have been duly coupled.
2) Front body f r ame (83101) holds the lens mount and
the shutter cocking mechanism.
3) Viewfinder base (R.4001) holds the rangefinder coupl-
ing mechanism and the rangefinder base .
- 2 -
4) Viewfinder casing (R5001) contains the dust cover
glass , the eyepiece lens and other parts .
5) Backlid frame (M2001) holds t h9 pressure plate at the
film- loading side and the film counter mechanism at
the film take- up s i de .

The various mechanisms and subassemblies are fitted to
the main body frame (B3401) and are intercoupled. The backlid
and lenses are removable .
With the l ens of the camera facing the viewer , the
shutter release mechanism is located in the righthand portion
of the main body frame (B3401) 1 beneath the shutter button .
In the l eftha.nd portion of the main body frame is the light
. barrier mechanisn , Ylhile to the lower portion of the body
frame is attached the linkages which couple the shutter
cocking mechanism in the front body to the film take-up
mechanism in the backlid. In between the viewfinder casing
and the main body f r ame is assembled the die- cast viewfinder
base , and coupling is effect ed with the focus ing mechanism.
The focusing rack (B3311) of the f ocusi.~g mechanism
is secured to the front body frame by means of four(4)
screws so that the front body slides in and out of the main
body, the adjustment being effected by a pinion turned by
a knob . The plunger lever of the backlid is in the fonn of
a rack which is engaged by a pinion on the take- up spindle
, subassembly 136) . When the plunger is pulled out , the
:ilm is advanced one frame , and a claw on the plunger moves
the film counter to the next indication.

3. DISYtANI'LING AND REASSEMBLING CAUTIONS
3 .1 Lens mount
vlhen f itting the camer a body lens mount plate (B3102) ,
see that the bayonet spring (B3104) and the bayonet washer
(BJ105) do not get caught in between . After completion of
a ssembly, glue lightproofing braid around the periphery of
t he mount .
3 . 2 Shutter r elease mechani sm
After adjusting to obtain the proper release point ,
apply l acquer seal to the head of the eccentric screw
(B3204-B) to pr event l oo sening .
- 24 -
3.3 Focusing mechanism
After adjustment of the eccentric scr ew of the axle
(B3303) of the f ocusing lmob , do not fail to re- check the
flanges of parallelism.
After dismantling of the main body and adjustment of
focusing kn0b axle (83033) apply lightproofing lacquer to all
points vulnerable t o leaks .
For reassembling after removal of pinion shaft 83302 ,
use the CX) position as guide for proper gear meshing .
The semicircul ar slot cut in the rear of the focusing
knob B3301 is designed to take the stop pin . Assembl e with
the stop pin riding in the slot .

3.4 Dismantling procedure
The dismantling procedure for removal of the pini on
shaft B3302 is first to remove B3307 the lock screw B3309 .
Next peel off upper portion of cover leather (B3721) as shown
in the drawing , remove two (2) set screws and set screw B3303
of the focusing shaft bearing , and adjust by changing the
eccentricit y of B3303 .
3 . 5 Rangefinder coupling mechanism base
\'/hen fitting the rangef inder coupl ing mechani sm in the
main body frame , see t hat the tip of the wide- angle coupling
lever comes i n between coupling lever 83801 and the stud set
on the ratio lever R4005 . The for ked port ion of B3002 should
fit the grooved end of coupling pin B3003 .

Measurement Procedure
1) Uemove backlid and lens of camera to be checked
2) Move gage support upward by turning adjustment
knob , enough to posit ion standard form gage
3) Pl ace standard form gage on base; lower gage
support gently so that gage tips touch cross-
section of the form ~age lightly; slightly turn
back adjustment knob and turn the fo rm gage
ar ound its axis
4) After form gage has settled on the base , adj ust
the 3 dial gages t o zer o po int; dial gages
shoul d not be touched t hereafter
5) Move gage support upward by turning the adjust-
ment knob (no stop is provided)
6) A tach to the came ra the film gate and mount
t
gages ; set camera. fo cus at ro ; position camer a ,
back dovm , on the base so that bottom touches
guide pins
7) Lower t he gage support gentl y so that dial gage
tips touch the surface of the mount gage ;
compare readings wi th t hose obt ained f r om the
