  • Publication number: 20100026528
    Abstract: A slim self-luminous keyboard structure comprises a keyboard unit and luminous units. The keyboard unit has a press plane containing a plurality of press members, and a baseplate is arranged below the press plane and supporting the press members. The luminous units generate light, and the light is conducted to a luminous space defined by the press plane and the baseplate to make the luminous space have brightness sufficient to enable users to recognize the press members. The slim self-luminous keyboard structure does not use a backlight plate. Therefore, the present invention can reduce the thickness of a self-luminous keyboard and facilitate fabricating a slim self-luminous keyboard.

  • Publication number: 20090324833
    Abstract: A method for forming patterns on face membrane by air-drawing force when vacuum. A foamed polyurethane (PU) is injected on the surface of substratum cloth to form a face membrane. The face membrane is heated at a preset temperature by a preheating box to be continuously maintained in a softened condition before it is not thoroughly hardened. An airproof release film is attached on one side of the substratum cloth opposite to the face membrane. A roller having functions of vacuum and cooling has its superficial patterns being pressed and printed on the heated face membrane by the air-drawing force when vacuum.

  • Patent number: 7628500
    Abstract: A luminous keyboard includes a cap which has a bottom lid with a first light directing zone formed thereon. The cap also has a first light blocking surface on an outer surface corresponding to the first light directing zone. At least one luminous unit is provided to provide light to the first light directing zone so that the light projects to the first light directing zone is diffused and blocked by the first light blocking surface, and finally projected to a keyboard portion to illuminate keycaps. The bottom lid replaces the light directing layer used in the conventional luminous keyboards. Thus the interior space of the keyboard can be shrunk to make fabrication and assembly of the keyboard simpler. The keyboard thus formed is thinner and lighter and suitable for mass production.

  • Publication number: 20090295725
    Abstract: The present invention discloses a scroll wheel module, which comprises: a scroll wheel; a displacement seat accommodating the scroll wheel; and a carry seat arranged outside the displacement seat. The displacement seat has a receiving member, which receives the scroll wheel and implements the displacement seat to move in the same direction as the scroll wheel moves. The displacement seat has at least one actuation member, and the carry seat has at least one instruction switch corresponding to the actuation member. At least one support member is arranged in between the displacement seat and the carry seat. The support member implements the displacement seat to move horizontally inside the carry seat, which makes the actuation member trigger the instruction switch to generate and output an instruction signal. Thereby, the assembling process of the scroll wheel module is simplified, and the volume of the scroll wheel module is reduced.
