Abstract

Abstract PURPOSE: To make ease of writing independently of types of writing tools, by combining the pressing leakage fiber in which the refraction index is changed by pressing two directions in mesh. CONSTITUTION: The plate shape coordinate detector 2 consists of the light emitting side pressing leakage fiber and the photo detection side pressing leakage fiber. Under the photo detection side pressing leakage fiber 2a, the light emitting side pressing leakage fiber 2b is located in parallel to form the fiber set 2c. A number of parallel fiber sets 2c are located so that they are combined into two directions of X and Y axes. On the double layer of the fiber sets 2c, the light shield sheet 2d is located.
