Abstract:
1. A keyboard comprising: light emitting diodes, each of the light emitting diodes configured to emit light; light guide plates, each of the light guide plates includes a side surface that receives the light from the light emitting diodes, said each of the light guide plates diffusing the light in a direction along a surface of the light guide plates; key tops, each of the key tops has a light transmitting area, through which the light is transmitted, and the key tops are provided over the light guide plates, wherein rows of the key tops are parallelly aligned and columns of the key tops are unevenly aligned; gear link parts, each of the gear link parts corresponds to one of said each of the key tops, said each of the gear link parts vertically moves the corresponding key top; housing parts, each of the housing parts corresponds to and is provided below one of said each of the key tops, said each of the housing parts holds said each of the gear link parts which corresponds to the corresponding key top; rubber actuators, each of the rubber actuators corresponds to one of said each of the key tops and said each of the rubber actuators provides reaction force based on vertical motion of the corresponding key top; a membrane sheet which is provided below the rubber actuators, the membrane sheet having contacts, each of the contacts corresponds to one of said each of the key tops and said each of the contacts opens and closes based on the vertical motion of the corresponding key top; and a support panel provided below the membrane sheet and provided on the light guide plates, the support panel fixes said each of the gear link parts together with the corresponding housing part, wherein the side surface of said each of the light guide plates face each other interposing an area between the light guide plates, the light emitting diodes are provided at the area between the facing side surfaces of the light guide plates, said each of the light emitting diodes faces one of said each of the light guide plates to emit the light toward the corresponding light guide plate, and each of the facing side surfaces of the light guide plates are formed in a step-shaped configuration having a configuration of spaces between neighboring key tops, and a space between the light guide plates is positioned beneath the spaces between the neighboring key tops.
