A support structure of a portable keyboard (2) includes two front supports (12, 14) and a rear support (10). The front supports and the rear support can rotate to two predetermined angles respectively to form a confine within which a portable computer (6, fig 3) may be placed and supported. The rear support (10) supports a backside of the portable computer (6), and the front support (12, 14) push against a lower edge (62, fig 3) of the portable computer. Furthermore, both the front supports and the rear support can be closed onto an upper surface (4) of the portable keyboard (2).
