A key switch disposed on a base of a keyboard includes a key cap, a linkage bar, an edge plate and a recess portion. The key cap is disposed above the base. The linkage bar connects the key cap and the base. The edge plate is connected to the base. A slot is formed on the edge plate, and an end of the linkage bar is slidably latched in the slot. The recess portion is formed on the base and adjacent to the slot. A step is between a holding surface of the recess portion and a top surface of the base. The end of the linkage bar is caved in the recess portion and held on the holding surface of the recess portion when the end of the linkage bar is slidably latched in the slot.

Keyswitch and keyboard therewith

A light-emitting keyboard is disclosed, which comprises: a light guide plate, configured with a light entrance surface, a light emitting surface and a via hole; a light source, disposed next to the light entrance surface of the light guide plate; a frame, disposed on the light emitting surface of the light guide plate; an opaque material disposed on the via hole. With the aforesaid structure, light from the light source can be prevented from being emitting out from the via hole and thus can be evenly emitted out of the light guide plate.

Light-emitting keyboard

The invention discloses a key structure including a keycap, a base plate, and a support member. The keycap includes a slide part; the base plate includes an engagement part; the support member includes a first end and a second end for engaging the keycap and the base plate. The first end slides on the slide part, and the second end is engaged to the engagement part. Therein, the second end thereon defines a first direction and a second direction perpendicular to the first direction. The first and second directions are substantially parallel to the base plate. The engagement part restrains the second end from sliding along the first direction. The second end includes two block parts. The block parts are deposited on two sides of the engagement part for restraining the second end from sliding along the second direction.

Key structure

A spray painting tool for painting key caps is disclosed, which comprises: a platform, having a plurality of columns formed on a top surface of the same; a panel, having a plurality of holes formed thereon at positions corresponding to the plural columns for allowing the plural columns to pass through the panel therefrom; a diaphragm, disposed on the panel while aligning a plurality of holes formed thereon with the plural columns for allowing the plural columns to pass through the diaphragm therefrom; and at least a holding unit, each being arranged on the panel at a position corresponding to one of the plural column for fixedly securing a key cap. As the diaphragm can be easily replaced, the spray painting tool can be used repetitively without worrying the stacking of residue paint on its panel. Moreover, as the spray painting tool is simple in structure and ease to use, painting key caps can be achieved with lower cost and less time.

Key cap painting tool

A keyboard with a wobble prevention structure, which is substantially a substrate having at least one press key arranged thereon while enabling each press key to be driven to move in a reciprocating manner following a specific direction, and having a plurality of position limit devices disposed on the substrate and beneath the periphery of a corresponding press key. In a preferred aspect, each position device is integrally formed with the substrate, or can be formed on the substrate by stamp forming technique, that each is used to confine the corresponding press key to move following only the specific direction, such that the wobbling of the press keys is prevented.
