Abstract
PURPOSE: To find a failure of a pantograph early by stretching a light fiber around a frame for the pantograph.
CONSTITUTION: When a failure has occured to pantograph 1, a light fiber 2 stretched around a frame is broken, light from a luminous body 3 will not reach a light receiver 4, and a relay 6 is switched off to inform the failure. Thus by the present simple apparatus a failure of a pantograph can be detected.
