Abstract:
A calculator's input interface includes a knob projecting above the top face of the casing. The knob is provided to allow numbers to be input manually. It is arranged to be able to be switched selectively into a plurality of active positions by tilting it in corresponding directions from an idle position. Each direction corresponds to a different digit to be entered in the calculator. The top face of the casing also has a plurality of first keys associated respectively with mathematical operators, the first keys being positioned relative to the knob in such a way that the ends of the fingers of a user's hand can each be located facing one of the first keys when the palm of the hand is turned downwards and the hollow of the hand covers the end of the knob.
