INDICATOR DEVICE

摘要

An indicator device wherein a prism member has a prism member side-surface and a transmission/reflection surface which is tilted relative to the prism member side-surface and into which light from a light source enters. Also, an adjacent member has an adjacent surface which is adjacent to the prism member side-surface. When the light source is being turned on, the light from the light source enters the transmission/reflection surface and transmits through the prism member. When the prism member is viewed from the front surface thereof when the light source is being turned off, the adjacent surface is visible by optical reflection at the transmission/reflection surface.
