Claims

[Scope of utility model registration request]

A writing shaft is provided with the tip protruding inside the case, and the tip side is displaced in a direction opposite to the writing direction as a writing operation is performed by pressing the tip against the writing surface, and the displacement of this writing shaft is detected. A writing type data input device equipped with a means for recognizing a writing character shape and inputting the data to an information processing unit, wherein a writing device is provided in the case that surrounds the outer periphery of the writing shaft and contacts the outer circumferential surface of the writing shaft at the tip. An elastic tube is provided that bends and deforms in the direction of the writing shaft displacement as the shaft is displaced, and the bending and deformation of the elastic tube causes mechanical deformation on the outer circumferential surface of the elastic tube, and the amount of mechanical deformation is converted into an amount of electrical change. A writing type data input device characterized in that sensors for conversion are attached to at least two positions shifted in the circumferential direction of the elastic tube.
