Claim 12

A device according to claim 10, wherein the housing of the keyboard has a generally smooth bottom surface, said keyboard being capable of being turned upside-down and placed in the recess in such a manner that said bottom surface lies substantially flush with the remainder of the top surface of the device.

Claim 13

A device according to claim 1 wherein in the vicinity of an edge adjacent to the user it includes downwardly-projecting positioning portions for co-operating with the edge of a work surface.

Claim 14

A device according to claim 12, further comprising: a single cable for connection to the central unit of a computer.

Claim 15

A device according to claim 13, wherein the cable leads into one of the positioning portions.

Claim 16

A device according to claim 1 wherein it has a single cable for connection to the central unit of a computer.

Claim 17

A device according to claim 1 further comprising: cordless communication means for communication with an auxiliary peripheral device, and in particular with a mouse.

Claim 18

A peripheral device for a computer, the device comprising: a thin flat housing having a flat bottom surface for resting on a work surface and having a top surface that is generally planar and smooth; a keyboard and a flat screen disposed in a central zone of the device; and two blank zones situated on either side of said central zone; wherein the housing has a width in the range of about 24-32 inches and a depth in the range of about 16-24 inches, the width and depth dimensions being substantially greater than necessary for accommodating said keyboard and said screen to enable the housing to constitute a desk pad that permanently occupies a portion of a work surface.

Claim 19

A peripheral device for a computer, the device comprising: a thin flat housing having a flat bottom surface for resting on a work surface and having a top surface that is generally planar and smooth; a keyboard and a flat screen disposed in a central zone of the device; and two blank zones situated on either side of said central zone; wherein the housing has a width in the range of about 24-32 inches and a depth in the range of about 16-24 inches, the width and depth dimensions being substantially greater than necessary for accommodating said keyboard and said screen to enable the housing to constitute a desk pad that permanently occupies a portion of a work surface.

Claim 20

A peripheral device for a computer, the device comprising: a thin flat housing suitable for resting on a work surface and having a top surface that is generally planar and smooth; a keyboard and a fiat screen disposed in a central zone of the device; two blank zones situated on either side of said central zone; a metal framework including a peripheral frame and receiving the keyboard and the flat screen; a transparent plate covering the screen; a thin plate having an opening for the keyboard and defining with the transparent plate a generally smooth surface; and a flexible membrane covering the transparent plate and the thin plate; wherein the housing has dimensions selected to enable the housing to constitute a desk pad that permanently occupies a portion of a work surface.

Claim 21

A peripheral device for a computer, the device comprising: a thin flat housing suitable for resting on a work surface and having a top surface that is generally planar and smooth; a keyboard and a fiat screen disposed in a central zone of the device; two blank zones situated on either side of said central zone; a metal framework including a peripheral frame and receiving the keyboard and the flat screen; a transparent plate covering the screen; a thin plate having an opening for the keyboard and defining with the transparent plate a generally smooth surface; and a flexible membrane covering the transparent plate and the thin plate; wherein the housing has dimensions selected to enable the housing to constitute a desk pad that permanently occupies a portion of a work surface.
