PURPOSE:To shorten the key operation time for retrieval to simplify the retrieval operation by using a character or a character string in the cursor position as the retrieval character or the retrieval character string to start retrieval by the operation of a retrieval key. CONSTITUTION:A cursor is moved to a character string to be corrected in a sentence and a retrieval key 13 is operated. On the basis of this operation of the retrieval key 13, a timer 10 is turned on and the retrieval character string is taken out from a sentence memory 3, where character data inputted by an input device 1 is stored, and is stored in a buffer 7 for retrieval. Characters whose character length is determined by the timer 10 are selected from character strings following the retrieval character string and are successively stored in a buffer 8 for taking-out. Contents of the buffer 7 for retrieval and those of the buffer 8 for taking-out are compared with each other by a comparator 9, and a CPU 2 performs the control in accordance with comparison results, and the retrieval operation is terminated if this comparison results in coincidence. Thus, the key operation time for retrieval is shortened and the retrieval operation is simplified.
