Abstract
Abstract A device for the input of alphanumerical data for apparatus of small size. The device comprises a keyboard formed of zones and members for the introduction of data, a monitoring display having luminous segments and electronic memorizing and decoding means, with the introduction zones enabling composition of the data, segment-by-segment, actuation of a zone making it possible to activate the segment of the display corresponding to this zone, the geometrical arrangement on the keyboard of the said zones being directly related to the arrangement of the segments of the display.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
107 words
A device for the input of alphanumerical characters for apparatus of small volume with a keyboard, comprising: zones and members for the introduction of characters; a monitoring display with a plurality of luminous segments; and electronic means coupled to said zones and members and said display, for memorising and decoding the characters; each of said introduction zones being coupled with one segment of said monitoring display; said electronic means enabling the characters to be formed segment by segment in response to actuation of said zones; said zones being geometrically arranged on the keyboard so as to correspond directly to the arrangement of the segments of said display.
Claim 2
Independent Claim
107 words
A device for the input of alphanumerical characters for apparatus of small volume with a keyboard, comprising: zones and members for the introduction of characters; a monitoring display with a plurality of luminous segments; and electronic means coupled to said zones and members and said display, for memorising and decoding the characters; each of said introduction zones being coupled with one segment of said monitoring display; said electronic means enabling the characters to be formed segment by segment in response to actuation of said zones; said zones being geometrically arranged on the keyboard so as to correspond directly to the arrangement of the segments of said display.
Claim 3
Dependent Claim
34 words
A device according to claim 1, in which said zones and the said introduction members are each formed of a sensitive element capable of being individually actuated in order to actuate corresponding display segments.
Claim 4
Dependent Claim
14 words
A device according to claim 2, in which said sensitive elements are mechanical keys.
Claim 5
Dependent Claim
13 words
A device according to claim 2, in which said sensitive elements are pick-ups.
Claim 6
Dependent Claim
25 words
A device according to claim 2, including a display having seven segments and a keyboard having seven introduction zones, each formed of a sensitive element.
Claim 7
Dependent Claim
64 words
A device according to claim 1, wherein said introduction zones include a pair of sensitive elements, capable of being individually actuated for activating said display segments, said pair of elements being geometrically arranged so as to correspond directly to the arrangement of said segment on the keyboard, each of said elements being capable of belonging to more than one of said pairs of elements.
Claim 8
Dependent Claim
32 words
A device according to claim 6, in which the number of said sensitive elements is less than the number of said display segments with said elements of said pairs being actuatable simultaneously.
Claim 9
Dependent Claim
27 words
A device according to claim 7, in which the elements of said pairs are actuatable in sequence, the order of actuation of said elements being as desired.
Claim 10
Dependent Claim
44 words
A device according to claim 1, in which some of the said introduction zones are formed of the combination of a plurality of sensitive elements, with said introduction zones being capable of being actuated according to a predetermined code for actuating the display segments.
Claim 11
Dependent Claim
49 words
A device according to claim 1, including a member for enabling the alphanumerical characters which are instructions controlling functions of the apparatus to be distinguished from the characters which are items of information to be memorised, actuation of said member being indicated by the activation of a reference mark.
Claim 12
Dependent Claim
20 words
A device according to claim 1, including a member for enabling introduction of alphanumeric characters contained in said memorising means.
Claim 13
Dependent Claim
27 words
A device according to claim 1, including a member which makes it possible to erase all or part of a character introduced into the same memorising means.
Claim 14
Dependent Claim
33 words
A device according to claim 1 in which a second action on one of said zones cancels the effect of a first action, permitting the erasing of the luminous segments of said display.
Claim 15
Dependent Claim
38 words
A device according to claim 1, including a circuit providing a signal for introducing the characters into the device after a delay measured from the last action of the user on any of the zones of said keyboard.
Claim 16
Dependent Claim
25 words
A device according to claim 1, in which actuation of one of said zones corresponding to a first luminescent display segment extinguishes said first segment.
Claim 17
Dependent Claim
28 words
A device according to claim 1, in which the small number of said elements and the arrangement thereof on the keyboard permit said zones to be actuated manually.
