2. NOMENCLATURE
The basic components of the camera (fig. 3) are: shutter, lens, rangefinder, viewfinder, self-timer mechanism mounted
on the body, and removable back cover.
Shutter cocking is by turning the winding knob (5). The shutter speed scale (4) is engraved on the winding knob. The
scale has numbers 2, 5, 10, .... up to 1000 (or 1250), which stands for 1/2, 1/5, 1/10, .... 1/1000 (1/1250) sec.,
respectively.
The shutter mechanism is linked to the film transport and frame counter mechanisms. By turning the winding knob
(5), the shutter is simultaneously cocked, with the frame advance and the of the disc counter moves up by one
division. With this design, double exposures are prevented.
The shutter is released by the release button (6) or by activating the self timer release (1).
The shutter release button has a threaded hole to accommodate a shutter release cable.
Focusing of coinciding the second image from right window (2) and left window (11) into one, which is made
possible by an optical compensator in the rangefinder mechanism.

The rangefinder mechanism is connected to the lens focusing mechanism, and thus, when the rangefinder images
coincide, the lens is focused correctly. The compensator turns by rotating the gear wheel (9).
A distance scale is engraved on the lens focusing mount, graded from 0.9 to infinity (fig. 4). All numbers represent
distances in meters.
