摘要： An apparatus for illuminating instrument pointers comprises a dial board having a shaft hole, pointer shafts provided perpendicularly to a pointer shaft drive unit and projecting through the shaft hole to the front of the dial board, a light conductive member having a light receiving section and a light transmission section made of a transparent material and disposed behind the dial board, a plurality of instrument pointers each having a collar section and a pointer section made of a transparent material and mounted on the pointer shaft such that a light beam emitted from the light transmission section is introduced through the collar section, and a light emitting member provided oppositely to the light receiving section. A light beam from the light emitting member is propagated through the light conductive member to the collar section and then to the pointer section, so that each instrument pointer is illuminated.
