Abstract: An illuminated keyboard includes a light guiding substrate, a support plate, a plurality of keycaps, and a plurality of liftable connecting member. The light guiding substrate has an upper surface and a lower surface. The upper surface includes a plurality of assembly areas, each of the assembly areas has an assembly structure. The support plate is above the light guiding substrate, and the support plate has a top surface and a bottom surface. The support plate is provided with a plurality of first penetrated portions, each of the first penetrated portions corresponds to the corresponding assembly area, and each of the assembly structures passes through the corresponding first penetrated portion. The keycaps are above the support plate and corresponding to the assembly areas. Each of the liftable connecting members is connected to the corresponding keycap and the assembly structure of the corresponding assembly area.

Abstract: A keyboard device includes a bottom plate, key caps, a circuit board, reset members, and assembly structures. The bottom plate has assembly regions. The key caps are above the bottom plate and correspond to the assembly regions. The circuit board is under the key caps. The key caps are abutted by the reset members. The assembly structures are between the bottom plate and the key caps. Each assembly structure includes an assembly member and a long rod. The assembly member is on the assembly region. The long rod is on the assembly member and is capable of moving up and down relative to the bottom plate. Each key cap includes a clamp portion. The clamp portion is on the long rod. The key cap is connected to the bottom plate via the clamp portion and is swingable about the long rod relative to the bottom plate.

Abstract: A keyboard device includes a base plate and a plurality of keyswitches disposed on the base plate. At least one of the keyswitches includes a keycap, two linkages, and two magnetic attraction members. The linkages are connected between the base plate and the keycap and configured to guide the movements of the keycap toward and away from the base plate. The magnetic attraction members are rotatably connected to the linkages, respectively, and are configured to attract each other. When the magnetic attraction members abut against each other, the keycap is at a highest position relative to the base plate. When the keycap moves toward the base plate from the highest position, the magnetic attraction members are separated from each other.

Abstract: The invention discloses a system and the corresponding method for booking international multiple-stop tickets. The system comprises at each node of an information network a global ticket reservation center which provides real-time information of global airlines and online booking and sale services, with at least one terminal device which provides customers an operating interface to book international tickets. The disclosed invention provides a method for at least one user who uses each terminal sale device distributed in the information network to accomplish the online operations of: inquiry and arrangement of flight schedules, inquiry of ticket prices, making reservations, canceling reservations, and changing the schedule for international tickets. Besides, the invention also provides travel plans that take the price and travel time as the prior consideration factors. The invention further includes an electronic monetary trading device to implement online ticket sale services.
