ABSTRACT:
A keyboard structure of a portable computer, in which the keyboard is divided by a dividing line into two separate keyboard divisions which can be pivoted apart about a pivot center of the top end of the dividing line. Two supporting rods which are pivotally connected to each other are respectively disposed on bottom sides of the keyboard divisions. Two thread guide blocks are respectively pivotally connected to outer ends of the supporting rods and fitted around opposite thread sections of the thread rod. By means of directly shifting apart the keyboard divisions, the thread guide blocks are driven to rotate and slide toward two ends of the thread rod. When the thread guide blocks rotate, the connecting portion of the supporting rods is gradually lifted, whereby when the keyboard divisions are stretched apart, the rear end of the keyboard is also lifted by a certain inclination angle to facilitate the operation of an operator.
