<p>PURPOSE:To obtain a coordinate input board having a long life by providing an electric insulating cloth-shaped body under a conductive rubber plate, and providing a coordinate reading contact substrate under said body. CONSTITUTION:A coordinate input board of a digitizer, etc. is provided with a tricot knitted cloth 7 of a nylon yarn whose thickness is, for instance, 15 deniers, as a cloth-shaped body consisting of a fiber having an electric insulating property, under a conductive rubber plate 5, and a coordinate reading contact substrate 3 is provided under said body. In this regard, a flexible protective film 4 is provided so as to protect said rubber plate 5. In such a way, a cloth-shaped body for usual clothes can be used as an insulating material, and an inexpensive coordinate input device can be manufactured. Also, when the pressure is applied by a steel pen, the fiber is fitted easily into the conductive rubber plate 5, and a coordinate position can be designated exactly.</p> |
