Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. An elevator display device comprising: a light-emitting display unit; a resin cover that is disposed in front of the light-emitting display unit so as to cover the light-emitting display unit, and that transmits light from the light-emitting display unit; and a metallic tone film that is disposed on the cover, that is made of a nano-layered film that is optically designed to have a metallic sheen, and that transmits the light from the light-emitting display unit. 2. The elevator display device according to claim 1 , wherein the cover is smoke gray in color. 3. The elevator display device according to claim 2 , wherein a surface of the metallic tone film is matt finished. 4. The elevator display device according to claim 1 , further comprising a remote controller light-receiving portion inside a space behind the cover, the remote controller light-receiving portion receiving an optical signal from a remote controller that is disposed externally. 5. The elevator display device according to claim 4 , wherein a remote controller operational state display portion that performs a light-emitting display in response to a light-receiving state of the optical signal at the remote controller light-receiving portion is disposed on the light-emitting display unit. 6. An elevator display device comprising: a light-emitting display unit; a resin cover that is disposed in front of the light-emitting display unit so as to cover the light-emitting display unit, and that transmits light from the light-emitting display unit; a metallic tone film that is disposed on the cover, that is made of a nano-layered film that is optically designed to have a metallic sheen, and that transmits the light from the light-emitting display unit; and a maintenance light that illuminates inside a space behind the cover.
