An improved coordinates input apparatus for designating a particular set of coordinates in three-dimensional space comprises a first magnet and a second magnet disposed so that respective, identical magnetic poles thereof are opposite each other with a gap therebetween. The second magnet is disposed so as to be tiltable in response to forces acting thereupon. The forces include a repulsive force arising between the first magnet and the second magnet and a pressing force exerted on the second magnet. A plurality of magnetoelectric transducers are disposed opposite the second magnet and surrounding the gap, and produce output voltages having values that vary according to a change in the gap between the magnetoelectric transducers and the second magnet, such that the differential voltage values of the transducer outputs indicate a set of X,Y coordinates in two-dimensional space.
