ABSTRACT:
An electronic typewriter which provides for significant simplification of machine operations. The typewriter includes automatic error correcting function associated with electronic controls and a memory. A series of text data which have been deleted during an incessant error correcting operation are stored in a specially provided buffer memory from which they can be recalled upon depression of a print initiating key for causing the corresponding text to be printed automatically. An LED indicates that the current print line contains printed characters which can be erased by such automatic correcting operation. The typewriter further provides for simplified indentation and a novel carrier return mode.
