摘要： A keyboard and a notebook computer with the keyboard are provided. The keyboard includes a membrane circuit board and plural keys. Each key includes a keycap, a bulge and a key frame. The bulge is connected with the keycap. The key frame has a guiding groove corresponding to the bulge. When the keyboard is in a usage status, the bulge is not pushed by the guiding groove and thus the keycap is at a higher position. Since the keycap is at the higher position, the movable distance of the keycap is increased and the tactile feel of depressing the keycap is enhanced. While a top cover of the notebook computer is closed to cover the keyboard, the key frame is moved horizontally. As the bulge is pushed by the guiding surface of the guiding groove, the height of the keycap is lowered.

摘要： A keyboard device includes plural keycaps and a membrane switch circuit member. The membrane switch circuit member is disposed under the plural keycaps. The membrane switch circuit member includes a wiring board and plural separate covering pads. The wiring board includes plural first trace patterns and plural second trace patterns corresponding to the plural keycaps. The plural second trace patterns are disposed on the wiring board and separated from the plural first trace patterns. There is a gap between each first trace pattern and the adjacent second trace pattern. The covering pads are disposed over the wiring board. The plural covering pads are aligned with the corresponding keycaps and cover the corresponding gaps. The covering pad has a triggering trace pattern over the corresponding gap.

摘要： A keyboard includes a base plate, plural keycaps, plural scissors-type connecting elements and a sliding plate. Each scissors-type connecting element has a bulge. The gliding plate has plural position-limiting structures. The keyboard is installed on a notebook computer and connected with a top cover of the notebook computer. For operating the keyboard, the bulge is received in a first step part of the position-limiting structure. Consequently, the keycap is at a higher height. Since the keycap is at a higher height, the movable distance of the keycap is large enough to provide better tactile feel. For storing the keyboard, the bulge of the scissors-type connecting element is moved to the second step part of the position-limiting structure. Consequently, the height of the keycap is reduced, and the keyboard has a slim appearance.

摘要： A key structure includes a keycap, a scissors-type connecting element, a metal triggering element, a switch circuit board, a base and a buffering element. The buffering element is integrally formed with the keycap, and fixed on an inner surface of the keycap. The buffering element is made of a soft material. As the keycap is depressed and moved, the buffering element is pushed by the keycap and subject to deformation. Consequently, the movable distance of the keycap is increased. That is, the tactile feel of depressing the keycap is enhanced.

摘要： A luminous keyboard includes a membrane wiring board, a key structure and a light-emitting element. The membrane wiring board includes a membrane switch. The membrane switch is electrically conducted through the key structure. The key structure includes a keycap, a connecting element and a soft light-shading element. The connecting element is arranged between the membrane wiring board and the keycap. The keycap is movable upwardly or downwardly relative to the membrane wiring board through the connecting element. The soft light-shading element is connected with the keycap and arranged around the connecting element. The at least one light-emitting element provides plural light beams. After first portions of the plural light beams are transmitted through the membrane wiring board, at least portions of the plural light beams are outputted from at least one light-transmissible region of the keycap. Consequently, the light utilization efficiency is enhanced.

摘要： The present invention provides an illuminated keyboard, including a light guide backplate and a plurality of keys connected to the light guide backplate. The light guide backplate of the present application is made of a light guide material and configured to transmit and project light rays to the keys. A printed circuit layer is formed on the light guide backplate and includes a plurality of conductive switch contacts. Each key includes a key cap, a connection member, and a support member, and the support member has a conductive contact. When the key cap is pressed, the conductive contact of the support member moves downward to trigger a conductive switch contact of the printed circuit layer to generate a switch signal. In the present application, a light guide backplate provides functions, such as guiding light, a function of printed circuit layer, and connecting a key, so as to reduce thickness of the illuminated keyboard.

摘要： An illuminated keyboard with an optical switch is provided. The illuminated keyboard includes a circuit board and plural keys. The circuit board includes plural light-emitting elements. Each light-emitting element is aligned with the corresponding key. The key includes a keycap, a housing, a triggering post, a light guide element and a light guide frame. The keycap is located over the housing. The triggering post, the light guide element and the light guide frame are disposed within the housing. Moreover, the light guide frame is arranged around the triggering post. After a light beam emitted by the light-emitting element is introduced into the housing, the light beam is guided to the light guide frame by the light guide element, and the light beam is scattered to a region around the triggering post and outputted from the keycap.
