Abstract

A keyboard has two segments connected to each other at their rear ends by a connector. The two segments can be pivoted about the connector through 90.degree. in the plane of a support surface for the keyboard. In one embodiment, each keyboard segment may be disposed at a maximum angle of 45.degree. to its support surface in a plane perpendicular to its support surface. Thus, the two segments may be tilted 90.degree. with respect to each other. The two segments may be separated and supported individually through three pivotally mounted supports on its bottom surface. Two of the supports are disposed adjacent the rear corners and pivot on the same axis while the third support is disposed adjacent a lower inner corner of the segment and pivots on an axis perpendicular to the pivot axis of the other two supports. Each of the supports has two legs of different lengths to permit various tilting configurations of each segment with one of the legs having an adjustable length in one embodiment.
