Abstract
An information processing apparatus includes first, second and third upper electrodes provided on a first substrate, and first, second and third lower electrodes provided on a second substrate opposed to the first, second and third upper electrodes, respectively. Also provided are first, second and third detectors for detecting a first capacitance between the first upper and lower electrodes, a second capacitance between the second upper and lower electrodes and a third capacitance between the third upper and lower electrodes. In addition, the apparatus also includes a first driver for moving the first and second substrates relative to each other in a first direction with respect to the substrate surfaces, a second driver for moving the first and second substrates relative to each other in a second direction perpendicular to the first direction, a third driver for rotating the first and second substrates relative to each other about an axis in a third direction perpendicular to the first and second directions, and a control unit.
