INPUT DEVICE OF ANGLES OF TANGENT ELEVATION AND RANGE INDICATION IN AIMING SIGHT FIELD OF VIEW Russian patent published in 2014 - IPC F41G11/00 G02B23/00 

FIELD: instrumentation.

SUBSTANCE: device comprises actuating screws 2 and 3, a handwheel 4 with the scale of angles of tangent elevation, clamps 5, 6 of the actuating screws, a ballistic cam 8, a linear displacement sensor in the form of a potentiometer with a housing 9 with a resistive layer and a movable contact 10, a tip 11, a spring 12, a signal processing device (SPD) 13, digital displays 14 optically connected to a lens 15 and a prism system 16 of connection with the eyepiece of the aiming sight. The handwheel 4 and the ballistic cam 8 are fixed to the actuating screw 2. The actuating screw 3 is placed inside the screw 2 along its longitudinal axis, composes a screw pair with it, and in rotation of the handwheel 4 it moves a tube 17 with the aiming sight cross hairs. In rotation of the handwheel 4 the ballistic cam 8 acts on the spring-loaded end of the movable contact 10 of the potentiometer, it is moved, the change of voltage at the output of the potentiometer is converted by the SPD 13 according to the ballistics tables of the used ammunition into a code of the digital display 14. The value of the range is displayed on the digital displays 14 and the lens 15 and is fed to the eyepiece by the system 16.

EFFECT: simplification of design of the device and reduction of energy consumption.
