Abstract

PURPOSE:To obtain a device where operations are easy and sure, by breaking or connecting the light from a light emitting means to a light receiving means dependently upon presence or absence of liquid in front of the mirror. CONSTITUTION:Mirror face 17 provided in cylinder 16 and optical fiber 1 which is led into this cylinder 16 and has one end arranged in a prescribed distance are provided. Liquid 18 of a small light transmittivity which can be interposed arbitrarily in front of mirror face 17 and a material consisting of the light emitting means and the light receiving means connected to optical fiber 1 are provided. Then, the light from the light emitting means to the light receiving means is broken or connected dependently upon presence or absence of liquid 18 in front of mirror face 17. Light breaking or connection can be performed surely only by putting the device horizontally or inclining the device as shown in figures.
