ABSTRACT:
The present electronic typewriter comprises a memory for storing English sentences inputted into the electronic typewriter by operating its keyboard, a dictionary memory, in which data on plural English words are stored, and a spelling check control system. The typewriter is also provided with a checking execution key for checking the spelling of each English word of the English sentences stored in the memory. When the checking execution key is operated, a English sentence data stored in the memory are read out by the spelling check control means which judges the coincidence with those stored in the dictionary memory. If it is judged by the spelling check control means that the English words of the English sentences stored in the memory include a word not corresponding to any of the English word data stored in the dictionary memory, the printed position of the word on the printing paper is determined by a printed position detection means on the basis of the English sentence data stored in memory. A feed means and a carriage movement means are driven through the action of a drive control means on the basis of the printed position determined by the detection means, to guide a printing head to the printed position. Once all of the printed misspelled words have been corrected, the spelling correction confirmation mode is automatically cancelled.
