A keyboard 1 is adapted both to operations making use of the entire keyboard, and to operations involving essentially the numeric section of the keyboard only, by said keyboard being provided with a wrist supports pivotally mounted in the lower edge 8 of the keyboard. The wrist support can be turned in or retracted under the keyboard, or it can be turned outwards to a position where the wrist support substantially forms an extension 6 of the keyboard topside. The mounting of the wrist support has been intentionally performed with a certain rotational friction which is sufficient for the support to be retained in its retracted position even when lifting the keyboard. <IMAGE> |
