ABSTRACT:
An electronic typewriter comprises a printing head, a carriage on which the printing head is movable along along a printing line, a keyboard including various keys, a carriage pointer for indicating the position at which the carriage is presently located, a line buffer having sequential memory locations corresponding to printing positions on the printing line, and a control circuit for performing a character key processing when a character key is operated and a space key processing when a space key is operated. In the electronic typewriter, the control means is constructed so as to perform a carriage return processing when a carriage return key is operated, in which processing the spelling of such a word is checked that one of the characteristic codes forming the word or a space code following the word is stored in a memory location of said line buffer specified by the carriage pointer, the carriage and carriage pointer are retuned to a predetermined home position thereafter, and the returning of carriage and carriage pointer is omitted when an error is detected in the spelling check.
