Abstract

PURPOSE:To cinstitute so that a character can be cut even if the character is wirtten, jumping out from the entry frame, by deciding the character by the specific number of strokes, and also cutting a character stroke to be decided next in accordance with a result of said decision. CONSTITUTION:An input data write control part 40 writes coordinates of a position of a pen pressed by a character input tablet, in a coordinate memory 30, and interrupts and controls to a character cut recognition control part 70 as occasion calls. The character cut recognition control part 70 reads out in order the contents of an address of an indicating coordinate memory of a read-out counter RC, and decides whether they are ''-1'' or not. In case when they are not ''-1'', it is decided that a coordinate data has been inputted, and subsequently, whether a character stroke end exists or not is decided. If a bit of the stroke end is set, it is decided to be the end of the storke, a stroke counter SCNT is added by ''+1'', and whether the number of strokes is ''2'' or not is decided. In cas of ''2'', the character cut control part 70 sends a start signal to a character recognizing part 50.
