Abstract: A touch pad device, for use in a portable computer, includes a touch pad housing that is recessed into and integrally formed on a top surface of a key deck. A pad assembly is securely seated into the touch pad housing and includes a touch pad. A pad cover is fastened to the touch pad housing, with the pad assembly installed therebetween, by hooks. Since the touch pad housing is integrally formed on the key deck, the number of component parts of the touch pad device is minimized and the man-hours for assembly is reduced. Further, since the pad cover can be installed and separated from above the key deck, maintenance of the pad assembly is simplified.

Abstract: A touch pad device for a portable computer includes a key deck (20); a touch region (24) formed on a portion of the key deck (20); penetration portions (28) extending through the key deck (20) while being adjacent to the touch region (24); push buttons (32) integrally formed with the key deck (20) while being able to deform elastically inside the penetration portions (28); a touch pad (40) formed on a lower surface of the key deck (20) in a position corresponding to the touch region (24) for information input; a cover button (30) mounted on an upper surface of the key deck (20) to cover at least the push buttons (32) and the penetration portions (28), the cover button (30) having first and second button units (31) and (31?) able to deform elastically and compress the push buttons (32); and a board (42) having switches (44) toggled on/off by pushing the button units (31) and (31?).
