The Geneva mechanism is an essential component of many film projectors which works in concert with other projector components such as the [[shutter]] in order to transform a film strip composed of static pictures into what appear to be "moving images". It is a mechanism which converts rotational motion into periodic motion.

THIS PAGE IS A WORK IN PROGRESS

The Geneva mechanism is an essential component of many film projectors which works in concert with other projector components such as the shutter and intermittent sprocket in order to transform a film strip composed of static pictures into what appear to be "moving images". It is a mechanism which converts rotational motion into periodic motion.

How it Works

  • Dwell state
  • Pull-down
