1. INTRODUCTION
The technical specification and operating instruction is intended to teach the operation and maintence of the movie cameras
“KINOR-35N” model 9KSN and model 9KSN-M. It contains information necessary for full use of the technical aspects of the
systems and correct operation of the camera.
Information and operation instructions of the rear retaining rings and matte box are described in the corresponding document.
Information and operating instructions on the follow focus control 5KSN-KEP17, the disconnecting device 1UO-12, charger UZ,
discharger UR, and battery BA-3-16 are described in their respective carrying cases.
There are some variations allowed between the camera and this specification due to periodical updates in the camera system.
ATTENTION!
LENSES WITH OST 19-144-83 MOUNTS ONLY (DISTANCE FROM THE FOCAL PLANE TO THE SHUTTER IS
19MM),are permitted to be used on this camera.
2. PURPOSE
Movie cameras “KINOR-35N” model 9KSN and model 9KSN-M can be used for shooting from the shoulder, fluid head, geared
head, and Steady Cam. It allows shooting of usual and wide-screen movies on black and white or color 35mm film according to
GOST 4896-80.
The cameras can be used on sound stages and in various outdoor climates, with synchronous sound recording on the external
sound recorder.

5. CONSTRUCTION AND OPERATION OF THE CAMERA
The camera is designed for maximum convenience of the operator and for shortest possible time of the preparation for shooting.
General information on the camera operation is stated in the descriptions of the kinematical diagram, optical diagram (see
Appendix), and electrical diagrams (see Part 2).
General view of the camera is shown on the Picture 1 (see Appendix).
Picture 2 shows the camera (1) with the 150m mag (2), viewfinder (3), compendium (4), start-up device (5), video assist (8),
controlling device (9).
Picture 2a shows the camera with the 300m mag (10) (of the «Kinor-35C II» model 5KSN-2M camera), 300mm lens (11), stand
(12), 2-sided follow focus (13), bridge plate (14), plate, and long viewfinder (14a).
Picture 2b shows the camera with the 150m mag and mag tilt (14b). The camera can be set onto the flat surface in such setup.
5.1. The kinematics of the “KINOR-35N” camera.
The kinematics is shown on the Picture 3.
To move the camera mechanism, the electric drive (16) is used. There are claw couplings (15) and (17) on the shaft (I) of the
drive. One end of the shaft (I) is connected to the shaft (II) with the shutter (29) via the claw coupling (15). Other end of the shaft
(I) is connected to the shaft (III) with the pulley (18) via the claw coupling (17).
The grommet belt (19) encloses the pulley (18) and the pulley (20) (situated on the main shaft (IV)). This belt and the claw
coupling (24) transfers rotation to the shaft (V) of the claw mechanism (28).
The grommet belt (22) encloses the shafts (21), (23), (25). It transfers rotation from the main shaft (IV) to the shafts (VI) and
(VII) with the pulling sprocket (26) and the holdback sprocket (27) of the film track.
Movement of the feeding core (39) and the take-up core (34) in the 15m and 300m mags is accomplished by stand-alone winding
units built up on the direct-current motors (32), (37) with the smooth pulleys (33), (38).
Cinematic link if the motors with the cores is accomplished by the belts (31) and (36) through the pulleys (30), (35) situated on
the shafts (IX) and (X).
5.2. The optical schematics of the “KINOR-35N” camera.
The optical schematics of the camera provides the following features: generating the image of the objects by the lens on the film
at the frame window; parallax-less observing of the objects through the viewfinder and focusing on the ground glass;
desqueezing of the image during shooting of the wide-screen movies with the anamorphic lenses; generating the image of the
objects on the TV diode target array; taking of the light energy to the integral light meter; observing of the light meter indicator
and other service information in the viewfinder field of view.
Picture 4 shows the optical schematics of the camera.
The image of the shooting objects is produced by the lens (41) on the film in the frame window (42). While the film is pulled by
the claw mechanism, the frame window is closed by the shutter (29) (see Picture 3). Mirror surface of the shutter directs the light
onto the matted surface of the interchangeable ground glass (43) or (44) or (44a). Resulting image is identical to the image in the
frame window. The interchangeable ground glasses have a finder marks and frames designating the normal, wide-screen, Super-
35 and masked frame fields.
The image produced on the ground glass by the lens is observed by the operator through the optical system consisting of the:
mirror (61), prism (47), lens (46), mirror (45) and interchangeable viewfinders (51) and (53).
The viewfinder (51) is used during shooting of the normal movies. It has 6x magnification. The viewfinder (51) consists of the
prism VR-0° (48), lens (49), prism AR-90° (50), two mirrors (60) and eyepiece (52) with dioptric adjustment of ±5 dptr.
Deanamorphic viewfinder (53) is used during shooting of the wide-screen movies. It desqueezes the image and it has 7.2x
magnification in vertical direction.
The desqueezer consists of the prism VR-0° (54), cylindrical lenses (55) and (57), mirror (56), two mirrors (59) and eyepiece (58)
with dioptric adjustment of ±5 dptr.
For the convenience of the operator, the eyepiece slides BCD of the viewfinders (51) and (53) can be rotated on 180° around the
transversal slide AB. Resulting rotation of the image is compensated by the rotation of the prism (54) automatically.
The eyepieces of the viewfinders (51) and (53) are removable. It is possible to replace them with the long viewfinder (79)
consisting of the ground glass (80), lens (81) and eyepiece (82) with dioptric adjustment of ±5 dptr.
