Abstract
A coordinates input system includes a coordinates input apparatus and a pointing device. The coordinates input apparatus includes a detector detecting a voltage value of each intersection point between electrodes in an electrode part, and a determination part determining whether coordinates are input by the pointing device based on the detected voltage. The pointing device includes a switching part switching conductivity between a contact part and a gripper, and a controller switching the conductivity between the contact part and the gripper at a switching period longer than a detection period in the detector. The determination part determines whether the coordinates input into the electrode part are made by the pointing device based on a change in the voltage values of the intersection points within a time corresponding to the switching period.
