Abstract

PURPOSE:To make it possible to set the area of an input area to proper size that eliminates a writer's burden in handwriting characters and free from a futile space by providing an input area setting device that sets the area of the input area of a tablet variably. CONSTITUTION:A handwritten character recognizing device consists of an x.y coordinate detecting section 4, a window coordinate conversion processing section 5, a window area designating section 6, a window pitch designating section 7, a sampling circuit 8 and a sampling rate designating section 9. The designating section 9 designates sampling rate (a) in the sampling circuit 8 responding to the operation of input area setting switches 3L, 3M, 3S. That is, setting is made to make the ratio of the sampling rate (a) when the input area of a large area is set, and that when the input area of an intermediate area is set, and that when the input area of a small area is set is inversely proportional to the width of the input area, for instance, to become 1/20:1/15:1/10.
