<p>PURPOSE:To attain the smooth coordinate input without requiring the pressurization of an input board by providing an input pen equipped with a magnetic field generating part and a detector to detect the voltage on an electric wire. CONSTITUTION:The title device is equipped with an input pen 12 equipped with a magnetic field generating part 13 and a detector 14 to detect the voltage on an electric wire 23. When the input pen 12 equipped with the magnetic field generating part 13 is made approximate to a superconducting switching element 22, the critical current value of the superconducting switching element 22 is reduced by the magnetic field to occur from the tip of the input pen 12 and the voltage to occur due to the reduction is detected. Thus, without being influenced by the dirt of the input board, the electric wire incidental to the input pen is made unnecessary, the mechanism of the input pen is made easier, the pressurization of the input board is not necessary and a high speed coordinate input can be executed.</p> |
