  • Patent number: 8410382
    Abstract: In an operation panel device for an elevator, a switch provided with a switch main body and an operation portion is mounted onto the back surface of a faceplate. A retaining mechanism for retaining the switch main body in a predetermined mounting position is provided between a side surface of the switch main body and the back surface of the faceplate. The retaining mechanism includes an elastic member. The elastic member allows the switch main body to be moved to the mounting position by elastic deformation. Further, when the switch main body is moved to the mounting position, the elastic member is restored to an original state thereof to prevent the switch main body from moving from the mounting position.

  • Publication number: 20120305342
    Abstract: 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.

  • Publication number: 20120250318
    Abstract: An LED surface cover (1) consists of a resin molding and has amain reflector (2) which reflects light forward from a surface light source and a subsidiary reflector (3) having a reflection surface which reflects light emitted from an LED light source (4) to the main reflector (2). The main reflector (2) has an aperture portion (2a) were the LED light source can be disposed and has a curved surface for traveling light reflected from the subsidiary reflector (3) to a region forward from the surface light source. The subsidiary reflector (3) is disposed above the aperture portion (2a) formed on the main reflector (2). The reflection surface of the subsidiary reflector (3) has an inclination with respect to a surface of the aperture portion (2a). The present invention provides a lighting system capable of accomplishing surface emission by carrying out a simple method, even though the LED light source (4) having a strong directivity is used.

  • Publication number: 20120217842
    Abstract: An electrostatic operation device in which a variation in the amount of electric charges accumulated in an electret film caused by physical impact can be suppressed. The electrostatic operation device (electrostatic induction power generating device (1)) comprises movable electrodes (8), an electret film (5) so formed as to face the movable electrodes (8) at a space therebetween, and a stopper (401b) for suppressing the approach of the movable electrodes (8) to the electret film (5) within a predetermined space.

  • Publication number: 20120140479
    Abstract: 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.

  • Publication number: 20110209974
    Abstract: 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.

  • Patent number: 7960665
    Abstract: Provided is a pushbutton switch device provided with a switch case in which a depressing member is arranged which, when moved downwards, depresses a switch. Arranged inside the switch case is an operating member which, when depressed, comes into contact with the depressing member to move the depressing member downwards. Provided in the peripheral edge of the operating member are a plurality of engagement portions to be engaged with the peripheral edge of the switch case. When the operating member is depressed, the depressed portion of the operating member rotates downwardly using, as a fulcrum, the engagement portion corresponding to the depressed portion of the operating member.
