Abstract: According to a chassis assembly structure, in assembling a front chassis side assembly in a bottom chassis, a front chassis side assembly 120 is configured such that when an upper surface end of a mechanical holder 103 projected to the rear side of a mechanical holder 103 is brought into contact with a rear-side bent part 111 of a bottom chassis 101, and a front side thereof is rotated about the contact portion serving as a rotational support axis toward the bottom chassis 101, a lower part of a front chassis 105 is invited and fitted between an angled pressing tab 113 and an upright part 112 along an inclined surface of an angled pressing tab 113.

Abstract: An indicator device includes a light emitting element for emitting light, and a light conducting plate having a light incidence surface for conducting light from the light emitting element inside thereof and a light output surface, for a lighted indication by the light output surface. The light conducting plate has a triangular recess recessed to form with prescribed recess depths in one planer surface thereof, for light from the light emitting element to be reflected in part. The triangular recess has a recess extremity constituting a single vertex disposed in position on an optical axis of the light emitting element and nearer to the light incidence surface than other end parts thereof. The recess depths becomes shallower as the V-form recess extends from the recess extremity, allowing for an evenness of luminance of light over the light output surface formed on the light conducting plate.
