SOLUTION: When an operating projection 1 is varied, an upper printed board 7 tilts. Then the analog value acquired by the resonance actions and the mutual induction of coils attached to both upper and lower printed boards 7 and 8 is converted into the moving signals of a cursor that has the information on its moving direction and distance moved and then outputted.</p> |
