PURPOSE:To make a sure input possible by bringing the probe of an input pen into contact with a desired pin on a printed substrate and detecting coordinates. CONSTITUTION:When probe 11 of an input pen is brought into contact with a desired pin, for example, Pij14 on printed substrate 2, the current is flowed power source E of prove 11 to transistor Tr17 through resistance R0, pin Pij14 and steering diode Dij16, and then, this Tr17 is made connected. In respect to the column direction, Tr20 is made connected similarly and it is recognized that probe 11 has been brought into contact with coordinated Pij. As a result, a sure input is possible. |
