The optical schematic consists of the grid (40), prism (41) (AR-90°), three-elements lens (42), two-way mirror (43), and
dispersive safety glass (44).
The grid (40) contains transparent crosshair and rectangular easels with ‘40’, ‘75’, ‘100’ marks corresponding to the filed of
view of the 40mm, 75mm, and 100mm lenses.
The image and the easels are observed through the two-way mirror (43). The image within each easel is identical to the image
produced in the frame window by corresponding lens.

5.5.1. Electric circuit of the camera
The camera electric circuit is shown on the Figure 5.
The motor M2 actuates all kinematics of the camera. Required power is supplied from the power source unit through the pins 1-
6 and 19-24 of the connector Ш1.
The shaft of the motor M2 is cinematically coupled with the tacho-generator M1 which produces a feedback voltage
proportional to rotation speed of the motor M2. The feedback voltage goes to the control unit through the pins 112 and 13 of the
connector Ш1 to form a governing signal for the motor M2.
Resistor R11 included in line with the tacho-generator adjusts the feedback signal slope.
Photodiode Д2, IR-transmitting diode Д3, and amplifier assembled on transistors T1-T3 form pulses of the film movement
during camera’s run. This unit works as described below.
Bridges between perforation holes block a light flow from Д3 to Д2 during film movement. Voltage pulses are passed from the
resistor R1 to the amplifier. Amplified pulses are passed from transistor T3 to the pin 7 of the connector Ш1 and to the control
unit therefore.
Diodes Д4 and Д5 serve for marking events on the film. Required voltage comes from the control unit through the pin 9 of the
connector Ш1.
The button B1 blocks the camera with opened door.
Start-up device is connected through the connector Ш3. The start-up device has buttons B2 and B3 for starting the camera and
marking ‘events’ on the film.
