ABSTRACT:
A character processing apparatus such as an electronic typewriter which can erase the recorded characters on a word unit basis. The apparatus includes: a keyboard to input a plurality of character strings such as English words; a memory to store the character strings input by the keyboard; a printer head which can record the character strings stored in the memory onto a recording paper and can delete the recorded character strings; a deletion instructing device to instruct to delete one of the character strings recorded on the paper by the printer head; and a control which is constructed in a manner such that in response to the deletion instruction, when the printer head exists at the position corresponding to the character string recorded on the paper, this character string is deleted, and when the printer head does not exist at the position corresponding to the character string recorded on the paper, the printer head is moved to the position of the nearest character string and this character string is deleted. The printer head is a head of the type wheel printer mechanism. With the apparatus, in the word deleting mode, the running cost can be reduced, the throughput can be improved, and the word deletion can be easily executed by a simple operation.
