<p>PURPOSE:To obtain the printing of high quality, by printing after correcting the error in characters and symbols displayed on the display unit. CONSTITUTION:First, the operator keys the keys and inputs the characters to be printed by n rows. The input signal is coded and stored in the memory 5 via the control circuit 11. The circuit 11 restores the content of the memory 5 by every line and displays it on the display unit 4. If there are any character errors on the display of the unit 4, after operating the key and the address of errors is designated, the correct characters are input and the characters in error of the content of the memory 5 are rewritten. The circuit 11 restores the rewritten content into characters again and displays them on the unit 4. The operator repeats this operation until there is no error by observing this display, and after judging the display correct, the instruction of print is made.</p> |
