Abstract

PURPOSE: To improve lighting effect by leading a light beam to a photoconductive plate by an edge light system and by directlighting a scale plate in airtight contact with the reverse surface of the photoconductive plate.
CONSTITUTION: Transparent acrylie photoconductive plate 10, etc., is bent nearly in a L shape. In contact with the back surface of one blade 11 of this photoconductive plate 10, scale plate 20 of an opaque thin plate material high in surface lightness such as aluminium is made which has scale 21 on its surface. The flank of the other blade 12 of photoconductive plate 10 is made convex and mirror-finished to obtain reflecting surface (a). In the center of the other blade 12, light source 30 is arranged and a light beam is led to bent part 14 direct or after being reflected by reflecting surface (a). On bent part 14 of photoconductive plate 10, reflecting surface (b) is formed and a light beam from the other blade 12 is all reflected by this reflecting surface (b) toward blade 11 to light uniformly the entire scale plate 20, so that scale 21 can be read. In this way, lighting effect can be improved.
