A key structure including a baseplate, a key cap, a first lever, a second lever, a first magnetic member, a second magnetic member and a first buffer material is provided. The first magnetic member is disposed on the baseplate and located between the first lever and the second lever. The second magnetic member is disposed on the first lever and corresponding to the first magnetic member. The first magnetic member has a first portion. The second lever has a second central end. The first portion is adjacent to the second central end. When the key cap moves to a higher position, the first and second magnetic members move towards each other. The second magnetic member has a second portion and a third portion. The first buffer material is provided between the first and second portions and between the second central end and the third portion, respectively.

A keyboard structure and assembling method thereof are provided. The keyboard structure includes a baseplate, a keycap and a frame having a hook body. The keycap can be inserted into the frame and restricted by the hook body, so that the range of movement of the keycap is restricted. The keycap cannot be separated from the frame so that the coupling of the frame and the baseplate is not interfered by the keycap. Thus, the present invention can effectively simplify the assembling process of the keyboard.

A keyboard device includes plural key structures, an electronic paper display element and an illumination module. The electronic paper display element is disposed under the plural key structures. The plural key symbols corresponding to the plural key structures are displayed on the electronic paper display element. The illumination module is disposed over the electronic paper display element to provide a light beam to the electronic paper display element. Consequently, the plural key symbols are illuminated.

An electronic device may have buttons, a display, and a vibrator unit. Buttons may be included in electronic devices such as glass buttons, metal buttons, buttons that are assembled on printed circuit boards, and buttons that are partly formed from antenna structures. Button coatings may be used to improve the sliding performance of metal-on-metal buttons. A layer of polymer may be interposed between a button plate and a housing structure. A glass button member may have an underside on which a layer of patterned ink is formed. Elastomeric members may be used to reduce button rattle. Portions of a button may be provided with conductive features that form portions of an antenna.

A key structure including a baseplate, a key cap, a first lever, a second lever, a first magnetic member, a second magnetic member and a first buffer material is provided. The first magnetic member is disposed on the baseplate and located between the first lever and the second lever. The second magnetic member is disposed on the first lever and corresponding to the first magnetic member. The first magnetic member has a first portion. The second lever has a second central end. The first portion is adjacent to the second central end. When the key cap moves to a higher position, the first and second magnetic members move towards each other. The second magnetic member has a second portion and a third portion. The first buffer material is provided between the first and second portions and between the second central end and the third portion, respectively.

A key inputting apparatus includes: a substrate provided with a switch; a key having a depression surface and a back surface on an opposite side to the depression surface, and a contacting section projecting from the back surface in a first direction from the depression surface toward the back surface; a panel having an opening in which the key is arranged; a first plate arranged between the substrate and the key in the opening of the panel; a second plate supported by the first plate between the key and the first plate; and a third plate arranged between the first plate and the substrate. The first to third plates are formed with first to third through portions, respectively, through each of which the contacting section is passable. The second plate is formed with a leaf spring section urging the key in a second direction opposite to the first direction.

A key structure may include a switch shaft sleeve seat and a switch shaft accommodated in the switch shaft sleeve seat, where an end of the switch shaft penetrates the switch shaft sleeve seat and is movable relative to the switch shaft sleeve seat; two balance shaft sleeve seats on sides of the switch shaft sleeve seat, where each of the balance shaft sleeve seats may include a sleeve body and a top of each sleeve body may include a through hole. Moreover, the key structure may include two balance shafts respectively accommodated disposed in the sleeve bodies, where top ends of the balance shafts penetrate the through holes. Also, the key structure may include a key cap arranged above the switch shaft sleeve seat and the two balance shaft sleeve seats and fixedly connected to the switch shaft and the two balance shafts.

A movement mechanism includes: a case; a moving portion movable with respect to the case; and a support member that links the case and moving portion together and supports the moving portion so as to be movable with respect to the case. The support member has a plurality of pairs of first support portions and a plurality of pairs of second support portions, each of which is elastically deformable, has a plate-like shape, and extends between the case and the moving portion. The first support portions and second support portions are respectively placed on a first side and a second side in a moving direction of the moving portion so as to be symmetric with respect to the moving portion in plan view.

A keyboard including: a key top; a slide member that is attached to the key top, slides up and down, and presses a contact via an elastic member; a non-slide member that is attached to the key top, and never moves up and down; supporters that support the slide member and the non-slide member, respectively; wherein the slide member is restrained by the key top in a first direction, and is movable in a second direction vertical to the first direction, and the non-slide member is arranged diagonally with the slide member, is movable in the first direction, and is restrained by the key top in the second direction.

A keyboard device includes plural key structures, an electronic paper display element and an illumination module. The electronic paper display element is disposed under the plural key structures. The plural key symbols corresponding to the plural key structures are displayed on the electronic paper display element. The illumination module is disposed over the electronic paper display element to provide a light beam to the electronic paper display element. Consequently, the plural key symbols are illuminated.
