Abstract
Abstract In a computer having a keyboard for entry of data represented by a series of bytes and/or instructions, processor is provided for processing data entered via the keyboard with a control unit controlling the entry and processing of data. An activatable guiding device including a single digit display instructs the operator by displaying as a number of machine conditions to the operator, a number of signals corresponding to a plurality of configurations of a single byte output from the processor. The control unit generates an activating instruction for activating the display.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
152 words
In a computer, accounting or similar programmable machine having a keyboard for entering information represented by a series of multibit words and a stored program processing unit for processing said information, an operator guide device comprising a display device controlled by said processing unit for displaying to the operator a number of machine status warnings, said display device including a single character display cell adapted to display one character at a time of a group of characters which can be defined by one word of information, said characters being formed of a plurality of signs individually actuatable by a corresponding signal, and a decoder for selectively actuating a combination of said signs in response to a word received by said processing unit by generating a corresponding combination of signals, whereby a plurality of symbols can be displayed corresponding to a plurality of configurations of a single word output by said processing unit.
Claim 2
Dependent Claim
152 words
In a computer, accounting or similar programmable machine having a keyboard for entering information represented by a series of multibit words and a stored program processing unit for processing said information, an operator guide device comprising a display device controlled by said processing unit for displaying to the operator a number of machine status warnings, said display device including a single character display cell adapted to display one character at a time of a group of characters which can be defined by one word of information, said characters being formed of a plurality of signs individually actuatable by a corresponding signal, and a decoder for selectively actuating a combination of said signs in response to a word received by said processing unit by generating a corresponding combination of signals, whereby a plurality of symbols can be displayed corresponding to a plurality of configurations of a single word output by said processing unit.
Claim 3
Dependent Claim
27 words
An operator guide device according to claim 1, wherein the decoder is manually removable, whereby the user can vary the symbols corresponding to the various word configurations.
Claim 4
Dependent Claim
67 words
An operator guide device according to claim 2, further comprising error detecting means actuable by said processing unit in response to the occurrence of machine errors, and display flash means actuatable by said detecting means for conditioning the display to flash corresponding symbols, said flash means comprising a circuit controlled by a counter in said processing unit for temporarily disabling said decoder each time said counter overflows.
