Abstract

PURPOSE: To make the visual recorgnition of the peak part of the segments of display part by combining and arraying two or more kinds of the emission colors of light emitting diodes and giving differences in lighting time for each emission color.
CONSTITUTION: A display part 21 comprises providing light emitting diodes and reflecting plate in an enclosure 21a and disposing a plurality of rectangular shapes in parallel or series. Segments 211 thru 216 are set in green color and display the safety range through continuous lighting. Next, the segment 217 of the adjoining range displays preliminary announcement of danger, is disposed with a yellow light emitting diode and is flickered at 1Hz or other by an astable multi circuit or other. The segment 218 adjoining to this displays the dangerous range and flickers the light emitting diode of red color at the period smaller than that of the segment 217, e.g., 2 to 3 Hz. When the segment 218 is used, the segment 217 stops flickering. Thereby, the peak part of the segments may be readily visually recognized.
