Abstract
A code generator which has a plurality of selectable areas on an information plane of an information plate formed with a magnetostrictive material. At least one exciting winding is wound on the information plate at one end thereof for causing at least one magnetostrictive oscillation wave in the magnetostrictive material. A plurality of detecting windings are arranged on the information plate in parallel with the exciting winding to divide the information plane into a plurality of small areas. An information designating detector is pressed against a desired one of the plurality of the small areas. Coded information indicative of a desired one of the small areas is obtained in correspondence to the number of output pulses induced from the plurality of detecting windings until a detected pulse is obtained from the information designating detector by the magnetostrictive oscillation wave resulting from pulse excitation by the exciting winding and propagated in the magnetostrictive material.
