LETTER SEPERATE NUMBER AUTOMATIC PRINTER METHOD

摘要

The wordprocessor gives line numbers corresponding to the setting character types. The 1st step scans the depressed key to check and set a flag indicating the automatic line inserting mode in the 2nd step. The 3rd step detects the right side setting key. So does the 4th step the left side setting key. The 5th step identifies the carriage return key, the 6th step the register key firing the 7th step which registers the type of the line number, the 8th step the depresed character to clear all the set flags in the unappropriated environment. Finally, the 9th step moves a hammer to the correct position to type the sentence number according to the settig key.
