ABSTRACT:
An electronic typographic apparatus includes a multiline display. Coded typographic data for characters of various widths is stored in a character memory, the dot format for the display of characters in different scan lines being produced upon application of stored character data to character generating read only memories. The data entry position of the data entry line of the display is stored and new data is entered into the character memory with counting circuits being employed to keep track of the data entry line and position. The display is "rolled up" one line upon receipt of a carriage return signal, and in the backspacing function, stored data is deleted. The characters are displayed with proportional widths, as a function of an asynchronous pulsed stepping signal generated from a read only memory instantaneously responsive to coded signals of the character memory just prior to the display of elements of a character. The time interval between successive stepping pulses corresponds to the widths of characters to be displayed.
Rapid repetitive display of characters or spaces is provided in response to depression of corresponding keys for more than a predetermined time interval.
