Abstract
Abstract A word processing system for displaying and reproducing a plurality of alphanumeric characters on a solid state display and capable of printing from that display consisting of a housing containing an electronic keyboard with indicia markings on the keys. There is provided at least one solid state display device disposed adjacent to the housing and having a multitude of segments for reproducing the indicia identified on the keyboard. A logic means is connected to the keyboard and the solid state display, and scans the keyboard upon the depression of one or more keys to find out the identity of the keys depressed. A solid state memory is also connected to the logic means and contains coded information concerning the keyboard indicia so that a character can be generated and reproduced on the solid state display responsive to the keyed indicia. There is also provided a data storage means for sequentially recording each of the keyed indicia responses provided by the keyboard and a means for printing the indicia displayed on the solid state screen. A plurality of pages of information can be stored in the system and sequentially reproduced by the printer from the electronic display.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
115 words
A word processing system for displaying and reproducing alphanumeric characters comprising: a housing including an electronic keyboard with keys representing individual alphanumeric characters; at least one solid state reflective display for logic means connected to said keyboard and solid state reflective display for scanning said keyboard upon the depression of one or more keys; solid state memory means having stored coded character information and coupled to said logic means for sequencing said logic means for each of the keyed characters depressed and for generating a displayed character on said solid state display screen responsive to the character keyed; and print means coupled to said solid state display for reprinting the characters appearing on said display.
Claim 2
Dependent Claim
115 words
A word processing system for displaying and reproducing alphanumeric characters comprising: a housing including an electronic keyboard with keys representing individual alphanumeric characters; at least one solid state reflective display for logic means connected to said keyboard and solid state reflective display for scanning said keyboard upon the depression of one or more keys; solid state memory means having stored coded character information and coupled to said logic means for sequencing said logic means for each of the keyed characters depressed and for generating a displayed character on said solid state display screen responsive to the character keyed; and print means coupled to said solid state display for reprinting the characters appearing on said display.
Claim 3
Dependent Claim
22 words
The word processing system as recited in claim 1 wherein said at least one solid state display comprises a liquid crystal display.
Claim 4
Dependent Claim
30 words
The word processing system as recited in claim 2 additionally comprising recorded memory means coupled to said logic means for sequentially storing the coded character information produced by said keyboard.
Claim 5
Dependent Claim
51 words
The word processing system as recited in claim 3 wherein said liquid crystal display comprises at least one liquid crystal screen, a multiplex decoder and driver circuit having its output coupled to said screen and its input coupled to said logic means for sequentially displaying the alphanumeric characters on the screen.
Claim 6
Dependent Claim
17 words
The word processing system as recited in claim 4 wherein said print means comprises a photocopy machine.
Claim 7
Dependent Claim
50 words
The word processing system as recited in claim 5 wherein said at least one liquid crystal display is coupled to said housing adjacent said electronic keyboard and compromising a second liquid crystal display coupled to said at least one liquid crystal display and in optical contact with said photocopy machine.
Claim 8
Dependent Claim
69 words
The word processing system as recited in claim 6 wherein said liquid crystal displays comprise at least two liquid crystal screens superimposed with respect to each other wherein said screens have an identical dot matrix layout with respect to each other, wherein one of said dot matrix layouts is slightly offset with respect to the other in an amount sufficient to fill in the space between the matrix dots.
Claim 9
Dependent Claim
25 words
The word processing system as recited in claim 1 wherein said logic means comprises a microprocessor and said solid state memory means comprises a ROM.
Claim 10
Dependent Claim
17 words
The word processing system as recited in claim 3 wherein said recorded memory means comprises a ROM.
Claim 11
Dependent Claim
86 words
The word processing system as recited in claim 2 wherein said at least one liquid crystal display comprises four display screens superimposed with respect to each other and disposed in close adjacent proximity, said screens having identical dot matrix layout wherein each of the dot matrix layouts of adjacent screens are offset in one of four directions in an amount sufficient to fill in the space of adjacent dot matrix segments so that a character generated simultaneously on all four screens will be continuous without segmentation.
Claim 12
Dependent Claim
21 words
The word processing system as recited in claim 2 wherein said at least one solid state display comprises an electrochromex screen.
Claim 13
Dependent Claim
21 words
The word processing system as recited in claim 2 wherein said at least one solid state display comprises a PLTZ screen.
Claim 14
Dependent Claim
19 words
The word processing system as recited in claim 1 wherein said print means comprises a photoengraver having self-developing film.
Claim 15
Dependent Claim
17 words
The word processing system as recited in claim 3 wherein said print means comprises a photocopy machine.
Claim 16
Dependent Claim
42 words
The word processing system as recited in claim 1 additionally comprising a facsimile transmitter and receiver coupled to said logic means for sequentially transmitting and receiving alphanumeric character information to and from a remote source for display on said solid state display.
Claim 17
Dependent Claim
32 words
The word processing system as recited in claim 2 wherein said at least one liquid crystal display comprises a remote liquid crystal screen for displaying generated character information at a remote location.
Claim 18
Dependent Claim
34 words
The word processing system as recited in claim 14 wherein said keyboard additionally comprises print key means coupled to said photocopy machine for sequentially reproducing the alphanumeric characters reproduced on said liquid crystal display.
Claim 19
Dependent Claim
