Claims7
A support element of a keypad included in a keyboard of a data input device, wherein said support element forms a light guide comprising:
- an upper face parallel to the keypad;
- and
- first and second lateral tabs extending perpendicularly to the upper face, said first and second lateral tabs being situated so as to be facing each other, on opposite sides of said light guide and each comprising an oblong hole extending substantially vertically and passing through the respective lateral tab in a direction parallel to the upper face of the light guide, said oblong holes cooperating with two clips disposed on an internal structure of said data input device, enabling a translational motion of the light guide so as to put at least one dummy key of a printed-circuit board under pressure.
A data input device comprising:
- an upper half-shell;
- an internal structure;
- a printed circuit board having at least one dummy key;
- a keyboard comprising a keypad having keys;
- a support element forming a light guide taking position between the printed-circuit board and the keypad, the light guide comprising an upper face parallel to the keypad and first and second lateral tabs extending perpendicularly to the upper face, said first and second lateral tabs being situated so as to be facing each other, on opposites sides of said light guide and each comprising an oblong hole extending substantially vertically and passing through the respective lateral tab in a direction parallel to the upper face of the light guide, said oblong holes cooperating with first and second clips disposed on the internal structure of said data input device, enabling a translational motion of the light guide so as to put the at least one dummy key of the printed-circuit board under pressure.
