  • Publication number: 20090016056
    Abstract: Herein disclosed is an electronic device which can have, without deteriorating the effect of notification by light, an extended area to have electronic parts mounted thereon at the portion of the main body 20 covered with the accessory exterior panel 30, the extended area being extended in size compared with the conventional electronic device, the electronic device available for a cellular phone. The cellular phone 10 comprises a main body 20, an accessory exterior panel 30 detachably mounted on the main body 20, and four screws 50 for fixing the accessory exterior panel 30 to the main body 20. The main body 20 has LEDs and a light guide plate 22c irradiated by the LEDs. The light guide plate 22c is positioned to emit a light to the inner portion of the accessory exterior panel 30 through the side surface 30a of the accessory exterior panel 30.

  • Patent number: 6315142
    Abstract: A portable terminal device, capable of improving the releasing property of fitting pieces of an upper case and a lower case at the time of disassembling the appliance, and lowering generation of deformation or crack of the main body by bend or twist while maintaining a sufficient fitting holding force. In the main body of the portable terminal device, a plurality of fitting pieces are provided each in an upper case and a lower case for holding and fixing with each other. The fitting pieces have a fitting horizontal surface to be substantially parallel for holding with each other when the upper case and the lower case are engaged. A part of the fitting horizontal surface of the fitting pieces of at least one of the upper case and the lower case has a fitting twisted surface twisted in the direction away from the fitting horizontal surface of the other fitting piece in the fitting pieces.

  • Patent number: 6215602
    Abstract: The present invention is for providing portable communication device capable of reducing leakage of a light from the gap between a housing and the lens, improving the assembly property by simplifying the parts size administration and improving the holding strength of the lens in a portable phone comprising a lens for guiding a light from a light emitting member for advising receipt of call to the outside of the housing. Alight transmitting portion, a collar portion, and a fitting spring portion are formed in a lens. The collar portion and the fitting spring portion are interposed between a flat portion formed in a housing and an LCD panel. An engaging projection formed on the rear surface of the LCD panel is inserted through the fitting spring portion.

  • Patent number: 5645769
    Abstract: The vehicular humidified cool wind system includes a blower, atomizing means, a water tank and an air passage which are integrated, and is mounted on the ceiling above the driver to blow out a humidified wind downward. The air passage is divided into a humidified wind passage to be fed with atomized water and an ordinary wind to be fed with no atomized water. The air outlet has a double duct structure, an internal cylinder and external cylinder, in which the humidified wind having passed through the humidified wind passage is blown out of an internal cylinder whereas the ordinary wind having passed through the ordinary wind passage is blown out of an external cylinder around the internal cylinder. The humidified wind is prevented from diffusing while being surrounded by the ordinary wind, so that it efficiently reaches the driver to give him a cool feeling.
