Abstract

PURPOSE: To obtain a high-reliability unit which can be inspected and maintained easily by leading light emitted from a light source to a display part through several optical fibers equipped with photo switches.
CONSTITUTION: Light emitted from single or several light sources 33 strikes terminals of the m×n-number optical fibers (f11) to (fmn), propagates through photo switches PSW11 to PSWmn, and radiates from other-side terminals of optical fibers (f11) to (fmn) fixed respectively to display parts F11 to Fmn arrayed in a matrix of (m) by (n) of display board 31. Now, when a pattern is inputted to pattern input circuit 35, switch control circuit 34 turns ON required photo switches corresponding to the pattern, only opening terminals of optical fibers connected to those photo switches turning ON radiates light, so that the pattern will be displayed on display board 31.
