Abstract:
1. An indicator apparatus comprising: a light source; a prism member comprising: the prism member transmitting through the front surface the light from the light source; and an adjacent member that has an adjacent surface that is spaced apart from and immediately adjacent to the prism member side surface in a direction substantially perpendicular to a direction of transmission of light from the light source, wherein light from the light source enters the prism member through the inclined first side of the transmitting and reflecting surface when the light source is lit, and wherein the adjacent surface is visible through the front surface of the prism member due to optical reflection at the inclined second side of the transmitting and reflecting surface, which is opposite to the first side of the transmitting and reflecting surface, so that the adjacent surface is visible through the front surface of the prism member if the prism member is viewed frontally when the light source is not lit, wherein the adjacent member includes first and second adjacent members, the first adjacent member is a surface plate that has a button aperture, and the second adjacent member is an operating button that is disposed in the button aperture, and that is operated by a user, the adjacent surface being disposed on at least one of the first and second adjacent members, and the prism member being disposed between the first and second adjacent members, and wherein a plane formed perpendicular to the direction of transmission of light from the light source extends through each of the first adjacent member, the second adjacent member, the adjacent surface, the prism member side surface, and the transmitting and reflecting surface.
