Abstract:
To provide a display system capable of obtaining a sufficient quantity of homogenous light by lighting display lamps which are disposed at a corner of a margin of a housing without increasing the size of a substrate on which a light source is mounted.SOLUTION: A display system 2 includes: an operation screen 21 that is attached to an apparatus and receives an apparatus operation instruction; and a plurality of display lamps 10 that report conditions of the apparatus. The display system further includes: a substrate 12 on which a light source 14 is mounted; a housing 20 that covers the substrate 12; lens members 13 forming light emitters of the display lamps 10; and light guide members 11 that guide light emanating from the light source 14 to the lens members 13. The housing 20 has: openings 22, which expose the lens members 13, in a region encompassing a corner formed of an edge of an upper surface 20a, on which the operation screen 21 is disposed, and a flank 20b. A connection surface on which the lens members 13 are connected to the light guide members 11 is orthogonal to an advancing direction of light emitted from the light guide members 11.SELECTED DRAWING: Figure 5
