Abstract
A coordinate input apparatus includes a position-detecting unit and position-pointing devices. The position-pointing devices include a pen-type position-pointing device and a puck-type position-pointing device provided with a magnetic shielding member or short-circuiting coil for hindering the electromagnetic interaction between sensor coils included in the position-detecting unit and the pen-type position-pointing device. By providing in the puck-type position-pointing device a means for suppressing or cutting the voltage or current of a coil or resonant circuit included in the puck-type position-pointing device, the loading of the pen-type position-pointing device into a pen-type device supporting means provided on the puck-type position-pointing device can deactivate the means for suppressing or cutting the voltage or current of the coil or resonant circuit.
