Abstract: A collapsible keyboard includes a middle subframe, and right and left subframes respectively disposed at and connected to two sides of the middle subframe by two levers, each of which is pivotally mounted on each pair of the adjacent subframes. Thus, the right and left subframes are swingable relative to the middle subframe between a deployed position, where the subframes are aligned with each other in a row, and a collapsed position, where the left and right subframes are superimposed upon and abut against the middle subframe.
