Operation button for elevator

Landing operation panel for elevator

An elevator display device has a light-emitting display unit, a resin cover, and a metallic tone film. The resin cover is disposed in front of the light-emitting display unit so as to cover the light-emitting display unit, and transmits light from the light-emitting display unit. The metallic tone film is disposed on the cover, and transmits the light from the light-emitting display unit. The metallic tone film is made of a nano-layered film that is optically designed to have a metallic sheen.

In an indicator apparatus, a prism member includes: a prism member side surface; and a transmitting and reflecting surface that is inclined relative to the prism member side surface, and into which light from a light source is admitted. An adjacent member has an adjacent surface that is adjacent to the prism member side surface. The light from the light source is admitted into the transmitting and reflecting surface when the light source is lit, and passes through the prism member. If the prism member is viewed frontally when the light source is not lit, the adjacent surface is visible by optical reflection at the transmitting and reflecting surface.

In a push-button switch, a mark for conveying information to a user is disposed on a portion of a front surface of a push-button for operating a switch main body. A light-guiding plate is disposed between the switch main body and the push-button. A mark diffusing portion that diffuses injected light is disposed on a portion of the light-guiding plate that faces the mark. A mark light source portion injects light into the light-guiding plate so as to be directed toward the mark diffusing portion.
