ABSTRACT:
The present invention is a device for mounting a keyboard to a base for positioning the keyboard in a backward tilted position and for use by a hand of an operator. The keyboard has a front end, a rear end, a plurality of keys each having an uppermost surface, and an uppermost keyplane defined by the uppermost surface of the keys. In one embodiment, the device comprises first and second bracket members engagable with the base. The device further comprises a support tray comprising a support surface and a keyboard stop member. The support surface has a front portion and a rear portion and is adapted to support the keyboard. The support tray is engaged with the first and second brackets such that the keyboard may be orientated in a backward tilted position which is defined by the rear end of the keyboard being disposed below the front end of the keyboard and the uppermost keyplane being tilted backwards. The keyboard stop member is adapted to prevent the keyboard from falling off the support surface when the keyboard is in the backward tilted position. The device further comprises a palm rest movably engaged with the support tray.
