Abstract

PURPOSE: To prevent various kinds of trouble, before occurrence, caused by a progress of anomalous states, by detecting a condition, that the wire be out of place from its engagement groove in the runner, through a photoelectric switch, to operate an alarm method with the above detection.
CONSTITUTION: In prescribed locations of a guide rail 6, is formed a slit part, at both sides of which an arrangement is relatively made by projectors 29, 29' and light sensors 30, 39', with a photoelectric conversion element provided. And a photoelectric switch, constituted by those of the projectors and light sensors, will detect a position of wire 10 with respect to a runner 15 in the guide rail 6. When the wire 10 comes to be out of place from an engagement groove of the runner 15, an alarm method will be operated by an output of the photoelectric switch.
