Optical joystick, has a multiplicity of radiation sensors that detect the light from a radiation cone whose direction is controlled with a joystick lever, so that the sensor signals can be evaluated to derive the lever position

摘要

Joystick has a lever (1), a radiating arrangement and a multiplicity of radiation sensors (3), whereby the radiating arrangement generates a radiation cone (7) that can be moved relative to the radiation sensors by movement of the lever. Binary signals can be derived from the radiation sensors and indicate the position of the lever relative to the sensors.
