Title:
OPERATING LEVER POSITION DISPLAY DEVICE OF PORTABLE TYPE CONTROL DEVICE
Document Type and Number:
Japanese Patent JPS5975313
Kind Code:
A
Abstract:
PURPOSE:To prevent an accident and to make a titled device small-sized, light, and low in its power consumption by detecting an inclined direction and an angle of an operating lever, and displaying its result, in a control device for operating a large-sized loading and unloading machine by radio remote control. CONSTITUTION:Optical switch circuits 30, 50 detect an inclined direction and an inclined amount of an operating lever when a CPU35 outputs one signal from a control terminal 35d, they are outputted by a binary code, and light emitting diodes 8, 9 are turned on and displayed. Accordingly, the number of bits between the optical switch circuits 30, 50 and tri-state buffers 40, 60 can be reduced, and not only a wiring material is curtailed but also a mounting space can be reduced.
