ILLUMINATED KEYBOARD DEVICE

摘要

An illuminated keyboard device includes plural keys, plural light-emitting elements and a membrane switch circuit module. Each key includes a keycap and an elastic element. Each elastic element has a protrusion. The plural elastic elements are located over plural contacts of the membrane switch circuit module and connected with the plural keycaps. The plural light-emitting elements are located under the corresponding elastic elements. Moreover, the protrusions within the elastic elements and the contacts of the membrane switch circuit module are all ring-shaped structures, and each light-emitting element is aligned with the center region of the corresponding contact of the membrane switch circuit module. Consequently, while the protrusion is moved downwardly to push the corresponding contact, a corresponding key signal is generated.

主权项

1. An illuminated keyboard device, comprising:
plural keys comprising plural keycaps and plural elastic elements, respectively, wherein the elastic elements are located under the corresponding keycaps, and each of the plural keycaps comprises at least one light outputting zone; plural light-emitting elements located under the corresponding elastic elements, and emitting plural light beams to the corresponding light outputting zones; and a membrane switch circuit module located under the plural keys, wherein the plural elastic elements are disposed on the membrane switch circuit module, and the membrane switch circuit module comprises:
an upper wiring plate comprising plural upper contacts, wherein each of the plural upper contacts is located under the corresponding elastic element;a lower wiring plate located under the upper wiring plate, and comprising plural lower contacts corresponding to the plural upper contacts; anda spacer layer arranged between the upper wiring plate and the lower wiring plate, wherein the plural upper contacts and the plural lower contacts are separated from each other by the spacer layer,wherein each elastic element has a protrusion, and the protrusion is disposed within the elastic element and located over the corresponding upper contact, wherein when one of the plural keycaps is depressed, the membrane switch circuit module is pressed by the protrusion, so that the corresponding upper contact and the corresponding lower contact are contacted with each other to generate a corresponding key signal.
