Abstract:
An input device for inputting characters and symbols comprising:an information exchange code main memory having a column index and a row index said information exchange code main memory effective for memorizing an address reference table;said column index having 10 bits;said column index effective to select a column of said address reference table;said row index having 10 bits;said row index effective to select a row of said address reference table;an input keyboard for alternately inputting said column index and said row index;a means for inputting a first input thereby producing a first index;said first index effective to select one of said column and said row of said address reference table, and holding said one of said selected column and row in an ON state;a selected character confirmation display for displaying said one of said column and said row selected by said means for inputting, whereby said selected one of said column and said row is displayed on said selected character confirmation display;a means for inputting a second input thereby producing a second index;said second index effective to select another of said one of said column and said row of said address reference table, thereby determining a first selected character at an intersection of said selected column and said selected row;said first selected character being displayed on said selected character confirmation display;said information exchange code main memory having means to memorize said address reference table;means for canceling one of said input of said first index and said second index, such that one of said column and said row of said address reference table, corresponding to another of said input of said first index and said second index, remains in an ON state, whereby said one of said row and said column of said address reference table in said ON state is displayed on said selected character confirmation display; andmeans for inputting an index effective to replace said canceled one of said input of said first index and said second index resulting from said means for canceling, whereby said index selects a second character corresponding to an intersection of said selected column and said selected row, and said second selected character being displayed on said selected character confirmation display.
