Abstract
The invention relates to a keyboard (1) to be used, for example, at a computer terminal. The preferred embodiment comprises a keyboard (1) having mounted thereon a number of keys (5), the keyboard being formed in at least two segments (2,3) which are mutually detachable and/or pivotable and wherein each of the segments (2,3) of the keyboard (1) has mounted thereon some of the keys (5). The pivoting/detachable nature of the keyboard aims at reducing stress and discomfort to the user by eliminating contortion to the operators wrists. More particularly, discomfort to the user caused by pronation of the wrists and/or supination of the wrists is reduced.
