## Abstract

An illuminated keyboard equipped with light emitting keycaps includes a keyboard portion and a light emitting portion. The keyboard portion includes at least one circuit board contained a plurality of keyboard command portions and a plurality of press members located above the circuit board corresponding to the keyboard command portions that are depressible to trigger the keyboard command portions. Each press member has a press surface, a holding surface and a coupling surface interposed between the press surface and holding surface. The press surface and circuit board form a light projection zone therebetween. The light emitting portion includes a lighting unit to provide light to the light projection zone and a light mask plate. The light mask plate has an aperture to expose the press surface and a light mask portion overlapped over the holding surface.

## Claims

### Claim 1

An illuminated keyboard equipped with light emitting keycaps, comprising:
a keyboard portion including at least one circuit board contained a plurality of keyboard command portions and a plurality of press members located above the circuit board corresponding to the keyboard command portions and depressible to trigger the keyboard command portions, each press member including a press surface, a holding surface and a coupling surface interposed between the press surface and the holding surface, the press surface and the circuit board forming a light projection zone therebetween; and
a light emitting portion including a lighting unit to provide light to the light projection zone and a light mask plate which includes an aperture to expose the press surface and a light mask portion overlapped over the holding surface, the light mask portion masking light in the light projection zone projected towards the holding surface and confining the light in the light projection zone to project merely to the press surface and the coupling surface.

### Claim 2 (depends on 1)

The illuminated keyboard of claim 1, wherein the coupling surface is an inclined surface.

### Claim 3 (depends on 2)

The illuminated keyboard of claim 2, wherein the keyboard portion has a connection arm connecting to bottom edges of the coupling surfaces of abutting members and forming the holding surface.

### Claim 4 (depends on 2)

The illuminated keyboard of claim 2, wherein the coupling surface of the press member has a bottom edge horizontally extending toward the abutting press member of the press surface to form the holding surface.

### Claim 5 (depends on 1)

The illuminated keyboard of claim 1, wherein the coupling surface is a vertical surface.

### Claim 6 (depends on 5)

The illuminated keyboard of claim 5, wherein the keyboard portion has a connection arm connecting to bottom edges of the coupling surfaces of abutting members and forming the holding surface.

### Claim 7 (depends on 5)

The illuminated keyboard of claim 5, wherein the coupling surface of the press member has a bottom edge horizontally extending toward the abutting press member of the press surface to form the holding surface.

### Claim 8 (depends on 1)

The illuminated keyboard of claim 1, wherein the press surface further includes a transparent zone and an opaque zone.

### Claim 9 (depends on 8)

The illuminated keyboard of claim 8, wherein the transparent zone is a character notation.

### Claim 10 (depends on 1)

The illuminated keyboard of claim 1, wherein the coupling surface is a transparent surface.

### Claim 11 (depends on 1)

The illuminated keyboard of claim 1, wherein the coupling surface is an opaque surface.

### Claim 12 (depends on 1)

The illuminated keyboard of claim 1, wherein the keyboard portion includes an elastic support member to aid the press member to move against the circuit board.

### Claim 13 (depends on 1)

The illuminated keyboard of claim 1, wherein the circuit board includes an opaque layer corresponding to the press member and the light mask plate.

### Claim 14 (depends on 13)

The illuminated keyboard of claim 13, wherein the opaque layer is a reflective layer.
