POINTING DEVICE, KEYBOARD ASSEMBLYAND PORTABLE COMPUTER

摘要

A pointing device is attached to a keyboard assembly. The pointing device includes an operation post; a sensor substrate that converts force applied to the operation post into an analog electric signal; a logic substrate that is attached to a rear surface of the keyboard assembly and generates a digital signal to move a cursor from the electric signal; and a cable that connects the sensor substrate and the logic substrate to each other. It is possible to reduce the area of a portion protruding to a lower side from the rear surface of the keyboard assembly in the vicinity of the operation post and to lower the height of the portion by separating the sensor substrate and the logic substrate from each other. Since the cable is separated from a motherboard, it is possible to reduce noise entering the cable which transmits an analog signal.
