Abstract

PURPOSE: To improve a noise-proof property by separating a digital controller into a digital controller main body part and a man machine controller and by coupling them optically.
CONSTITUTION: 11 In the figure indicates a digital controller main body part which functions as an input device, and light emitting element 12 where an electric signal is given to output a light signal is mounted on the output part of 11. Man machine controller 13 which functions as an output device is provided with photo detector 14, and the signal of photo detector 14 is processed and is displayed on display part 15. Light emitting element 12 and photo detector 14 are connected by an optical fiber.
