Abstract
Abstract The system includes a case having a plurality of display portions, each of which can display a unit of information in a predetermined sequence. The system also includes a keyboard for generating said numerical units of information, a counter for controlling the sequencing of the display portions, and a shift register for storing the units of information before entering them on tape. The counter is connected to sequence through the various display portions serially and to lock at two selected display portions which are operated back and forth along with the proper associated units of information. The system also includes means for reading back the stored information from the tape and for transmitting the information to a remote computer or other data center.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
199 words
Data communication apparatus comprising a case comprising a housing, a plurality of windows in said case, each carrying a legend, light-producing means behind each window for lighting up and thus displaying the legend associated with that window, an array of display devices disposed adjacent to said windows for displaying characters in association with the legend displayed in each of said windows, a source of data information representing characters and energizable so that characters can be displayed in said display devices, first circuit means coupled between said source of data and said display devices for entering the character represented by said source, said first circuit means including a circulating shift register which stores signal bits representative of said characters and a decoder for coupling said signal bits to said display devices from said shift register, said shift register also being coupled through logic circuits to a tape recorder for recording said signal bits stored in said shift register, and second circuit means coupled to said legend-displaying means at each window for displaying said window legends one at a time in a series, with each window legend being displayed separately along with an associated display of data in said display devices.
Claim 2
Dependent Claim
199 words
Data communication apparatus comprising a case comprising a housing, a plurality of windows in said case, each carrying a legend, light-producing means behind each window for lighting up and thus displaying the legend associated with that window, an array of display devices disposed adjacent to said windows for displaying characters in association with the legend displayed in each of said windows, a source of data information representing characters and energizable so that characters can be displayed in said display devices, first circuit means coupled between said source of data and said display devices for entering the character represented by said source, said first circuit means including a circulating shift register which stores signal bits representative of said characters and a decoder for coupling said signal bits to said display devices from said shift register, said shift register also being coupled through logic circuits to a tape recorder for recording said signal bits stored in said shift register, and second circuit means coupled to said legend-displaying means at each window for displaying said window legends one at a time in a series, with each window legend being displayed separately along with an associated display of data in said display devices.
Claim 3
Dependent Claim
14 words
The apparatus defined in claim 1 wherein said second means includes a multi-position counter.
Claim 4
Dependent Claim
15 words
The apparatus defined in claim 1 wherein said second circuit means includes a flip-flop counter.
Claim 5
Dependent Claim
59 words
The apparatus defined in claim 1 wherein said second circuit means includes a flip-flop counter comprising a plurality of flip-flops, at least two of said flip flops being interconnected so that successive input counting pulses to said counter cause said counter to flip back and forth between said two flip-flops until the counter is reset to its starting state.
Claim 6
Dependent Claim
91 words
The apparatus defined in claim 1 and including a first signal-storage means coupled through signal processing circuits to said source of data information, a flip-flop counter having its outputs coupled through signal processing circuits to said legend-displaying means at each said window, a second signal-storage means, and a sequencing circuit coupled to the output of said first signal-storage means and the output of said flip-flop counter for sequentially feeding information held in said first storage means and the information represented by the state of said counter to said second storage means.
Claim 7
Dependent Claim
77 words
The apparatus defined in claim 5 and including a transmission path from said second storage means through signal processing and sequencing circuits to said first storage means and said counter to display in said windows and in said display devices the information stored in said second storage means. 7. The apparatus defined in claim 6 and including circuit means coupled to the output of said shift register for transmitting the information stored therein to a remote station.
Claim 8
Dependent Claim
174 words
Data communication apparatus comprising a case comprising a housing, a plurality of windows in said case, each carrying a legend, a lamp behind each window for displaying the legend associated with that window, an array of display devices positioned adjacent to said windows for displaying characters in association with each of said windows, a keyboard in said case including an array of keys representing characters to be displayed in said display devices, first circuit means coupled between said keys and said display devices for entering the character represented by said keys, said first circuit means including a circulating shift register which stores signal bits representative of said characters and a decoder for coupling said signal bits to said display devices from said shift register, said shift register also being coupled through logic circuits to a tape recorder for recording said signal bits stored in said shift register, and second circuit means including a counter circuit to said legend-displaying means at each window for displaying said window legends one at a time in a series.
Claim 9
Dependent Claim
174 words
Data communication apparatus comprising a case comprising a housing, a plurality of windows in said case, each carrying a legend, a lamp behind each window for displaying the legend associated with that window, an array of display devices positioned adjacent to said windows for displaying characters in association with each of said windows, a keyboard in said case including an array of keys representing characters to be displayed in said display devices, first circuit means coupled between said keys and said display devices for entering the character represented by said keys, said first circuit means including a circulating shift register which stores signal bits representative of said characters and a decoder for coupling said signal bits to said display devices from said shift register, said shift register also being coupled through logic circuits to a tape recorder for recording said signal bits stored in said shift register, and second circuit means including a counter circuit to said legend-displaying means at each window for displaying said window legends one at a time in a series.
Claim 10
Dependent Claim
17 words
The apparatus defined in claim 8 wherein said means associated with each window is a light-producing lamp.
Claim 11
Dependent Claim
14 words
The apparatus defined in claim 8 wherein said counter circuit includes a flip-flop counter.
Claim 12
Dependent Claim
54 words
The apparatus defined in claim 8 wherein said counter circuit includes a flip-flop counter comprising a plurality of flip-flops, at least two of said flip-flops being interconnected so that successive input counting pulses cause said counter to flip back and forth between said two flip-flops until the counter is reset to its starting state.
Claim 13
Dependent Claim
88 words
The apparatus defined in claim 8 wherein said counter of said second circuit means comprises a series of flip-flops and including means for setting said counter to a starting state and input means for feeding counting pulses to said counter, at least two of said flip-flops being interconnected so that after a predetermined number of input pulses have switched said counter from one position to the next, subsequent input pulses cause said two flip-flops to switch back and forth until the counter is reset to its starting state.
