Abstract
Abstract A man-to-machine peripheral communication device comprising a matrix having a number of matrix positions, a plurality of character supports each of which may be inserted in one of said positions, and interconnection means between said support and matrix for translating the character or characters borne by said supports into coded electrical signals. The said translating means may be electromechanical, electromagnetic, electrostatic or optical. The coded signal may be visually displayed or transmitted to data processing or storing equipment.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
205 words
A device designed to set up, display, encode and store information composed of characters, to be conveyed to data processing equipment or to an information storage unit, comprising in combination: a. a plurality of separate supports each bearing at least one of such characters and each incorporating code-forming elements representing the character associated therewith; b. a matrix made up of a number of matrix positions, each capable of accommodating one of said supports and equipped with a coder unit operated upon by said code-forming elements provided on said one of said supports placed in said matrix position and working out an encoded version of at least one of the characters borne by the latter said support; and c. circuits converting the encoded versions worked out by said coders into electric signals, and means for processing and storing informations constituted by said signals; d. each of said coder units including an electric circuit fed from an electric current source and each of said encoded versions consisting of a voltage change appearing between two points in said electric circuit as the result of a corresponding change in the electrical characteristics of said circuit caused by the accommodation of said one of said supports on its matrix position.
Claim 2
Independent Claim
205 words
A device designed to set up, display, encode and store information composed of characters, to be conveyed to data processing equipment or to an information storage unit, comprising in combination: a. a plurality of separate supports each bearing at least one of such characters and each incorporating code-forming elements representing the character associated therewith; b. a matrix made up of a number of matrix positions, each capable of accommodating one of said supports and equipped with a coder unit operated upon by said code-forming elements provided on said one of said supports placed in said matrix position and working out an encoded version of at least one of the characters borne by the latter said support; and c. circuits converting the encoded versions worked out by said coders into electric signals, and means for processing and storing informations constituted by said signals; d. each of said coder units including an electric circuit fed from an electric current source and each of said encoded versions consisting of a voltage change appearing between two points in said electric circuit as the result of a corresponding change in the electrical characteristics of said circuit caused by the accommodation of said one of said supports on its matrix position.
Claim 3
Dependent Claim
48 words
A device as claimed in claim 1, in which said code-forming elements consist of sets of holes arranged at predetermined points on said supports, and in which each of said holes cooperates with a flexible electrically conductive strip to operate a corresponding electric contact in said electric circuit.
Claim 4
Dependent Claim
58 words
A device as claimed in claim 1, in which said coder unit includes a set of electric contact relays mechanically actuated by means of projecting parts arranged at predetermined points on said supports, and in which each of said projecting parts cooperates with a flexible electrically conductive strip to operate a corresponding electric contact in said electric circuit.
Claim 5
Dependent Claim
26 words
A device as claimed in claim 1, in which said code-forming elements consist of sets of electrically conductive areas arranged at predetermined points on said supports.
Claim 6
Dependent Claim
43 words
A device as claimed in claim 4 in which said coder unit includes a set of electric contact pairs so arranged that said conductive areas establish conductive connection between the two contacts of a contact pair located opposite each of said predetermined points.
Claim 7
Dependent Claim
52 words
A device as claimed in claim 1, in which said code-forming elements consist of sets of sections made of a material of high-magnetic permeability and arranged at predetermined points of said supports, each of said sections cooperating with a complementary magnetic circuit coupled with an inductive element included in said electric circuit.
Claim 8
Dependent Claim
31 words
A device as claimed in claim 6, in which said coder unit includes detector circuits whose states of magnetic polarization are affected by the presence or absence of said high-permeability sections.
Claim 9
Dependent Claim
24 words
A device as claimed in claim 6, in which said coder unit incorporates inductive circuit elements whose inductances are coupled to said high-permeability sections.
Claim 10
Dependent Claim
49 words
A dEvice as claimed in claim 1, in which said code-forming elements are made up of sets of sections made of a high-dielectric constant material arranged at predetermined points on said supports, and in which each of said sections cooperates with a capacitive element included in said electric circuit.
Claim 11
Dependent Claim
54 words
A device as claimed in claim 1, in which said code-forming elements consist of an assembly of light-reflecting and nonlight-reflecting areas located at predetermined points on said supports, and in which light reflected by each of said reflecting areas is received by a photoelectric cell which delivers an electric current to said electric circuit.
