<p>PURPOSE:To input information relating to extension in addition to position information, by inputting an optical scanning signal by use of many optical fibers formed like ears of a brush. CONSTITUTION:An optical fiber bundle 1 is slid on a scanning type display face. As a result, an optical signal on the picture enters the optical fiber bundle 1, and its optical signal is converted to an electric signal by a photoelectric converting element 2 and is inputted to an electronic computer. As for the optical fiber bundle 1, that which has 50mum-200mum diameter is desirable. As for lubricating treatment of the optical fiber bundle 1, a smooth writing taste is obtained by performing a coating treatment to the surface of each optical fiber by use of fluororesin.</p> |
