Abstract

PURPOSE:To improve the operability of the titled input device by using a superconductive material at least at the tip part of a pen case and adding a pick-up coil into said tip part of the pen case. CONSTITUTION:A superconductive material 10 is used at least at a tip part of a pen case 1 and at the same time a pick-up coil 3 is put into said tip part of the case 1. Thus the magnetic flux supplied through the tip part of the case 1 is transmitted to the coil 3 with no leakage. Therefore it is not required to form especially the coil 3 at the tip part of the case 1 so that this case tip part can be thinned. As a result, the input operability is improved with a coordinate input device.
