摘要： A key structure includes a supporting plate, a keycap, a scissors-type connecting element, a movable element and a coupling structure. The keycap is disposed over the supporting plate. The coupling structure is connected with the scissors-type connecting element and the movable element. For operating the key structure, the cooperation of the movable element and the coupling structure allows the keycap to be at a higher first height. Consequently, the tactile feel of depressing the key structure is enhanced. Moreover, the cooperation of the movable element and the coupling structure can lower the height of the keycap. Consequently, the key structure has a slim appearance.

摘要： A key structure includes a first movable plate, a second movable plate, a keycap, a first linkage lever and a second linkage lever. The second movable plate is disposed over the first movable plate. The keycap is disposed over the second movable plate. The first linkage lever is connected with the keycap and the first movable plate. The second linkage lever is connected with the keycap and the second movable plate. While the first movable plate is moved in a first direction and the second movable plate is moved in a second direction, the first linkage lever and the second linkage lever are moved in different directions, so that a height of the keycap is reduced.

摘要： A keyboard with a key accommodation function is provided, including: a keyboard base body, a plurality of keys, and a flexible rollable panel. The flexible rollable panel and the keys are adjacently disposed on the keyboard base body. The flexible rollable panel includes a panel surface, and a free end portion jointly disposed at one side of the panel surface. Each of the keys has a first matching surface, and the free end portion has a second matching surface. When the flexible rollable panel is unfolded, the second matching surface of the free end portion sequentially abuts against the first matching surfaces of the keys, so that each of the first matching surface is pressed downwards because each of the first matching surface is subjected to a downward vertical component from the second matching surface, thereby unfolding the panel surface above the keys, and reducing space occupied by the keys.

摘要： A keyboard device includes plural key structures, a membrane circuit board and a flexible light shielding element. Each key structure includes a keycap. The keycap has a first end surface and a second end surface. The membrane circuit board is located under the keycap. The flexible light shielding element is arranged between the keycap and the membrane circuit board, and includes a bottom layer and plural stopping walls. Each stopping wall includes a wall body and a platform part. The wall body is protruded from the bottom layer and in the direction toward the keycap. An included angle is formed between the wall body and the bottom layer. The platform part is protruded from the wall body. The platform part is arranged between the second end surface of the keycap and the bottom layer. The platform part is contacted with the second end surface.

摘要： A keyboard device includes a key switch, a base plate, a connecting element and a replaceable key. The replaceable key includes a coupling plate and a keycap. The connecting element is connected between the coupling plate and the base plate. The coupling plate includes a first sliding part. The keycap includes a second sliding part. When the second sliding part is slid relative to the first sliding part, the keycap is combined with the coupling plate or the keycap is detached from the coupling plate. Consequently, the keycap is easily assembled or disassembled. Moreover, since the connecting element is not touched during the process of disassembling the keycap, the connecting element is not damaged.

摘要： A luminous keyboard includes a key module, a light guide plate, a top-view light-emitting element and a light-shading element. The top-view light-emitting element emits a light beam. The light guide plate is located under the key module. The top-view light-emitting element is located under the light guide plate. A light-outputting surface of the top-view light-emitting element is contacted with the light guide plate. The light-shading element is disposed on the light guide plate for shading the light beam. A portion of the light-shading element is inserted into the light guide plate opening and formed as a reflective part in the light guide plate opening. After the light beam is projected on the reflective part and reflected by the reflective part, the light beam is transferred within the light guide plate and projected to the key module.

摘要： A keyboard device includes a key, a base plate, a membrane circuit board and a buffering part. The membrane circuit board is disposed on the base plate. The key includes a keycap and a stabilizer bar. The stabilizer bar is connected between the keycap and the base plate. The stabilizer bar includes a main bar part, a first linking part and a first insertion part. The first linking part is connected between the main bar part and the first insertion part. The buffering part is disposed on the base plate or the membrane circuit board and located under the first linking part. While a keycap is moved downwardly relative to the base plate, the linking part of the stabilizer bar is contacted with the buffering part. The contact point between the linking part of the stabilizer bar and the buffering part is used as a fulcrum.
