<p>PURPOSE:To obtain a position detector having high operability and high accuracy by detecting the maximum induced voltage level when a tablet part where plural magnetic plates and conductor plates are laminated by means of a position designating bar magnet. CONSTITUTION:A tablet part 100 is formed by laminating three sets of magnetic matters obtained by enclosing the warp and the weft woven into plain meaning into an insulated material and four sheets of conductor plates in the prescribed order and into a prescribed form. Then a point A of the part 100 is designated by a position detecting bar magnet 400 with its N pole turned down. Thus the induced voltage levels V1-V8 are obtained on the detection lines of the direction X. Each of these levels V1-V8 is maximum right under the point A. These voltage levels are obtained from a multiplexer 301 and therefore the X coordinate value with which the induced voltage level is maximum is calculated by a position detecting circuit 500 to obtain the X coordinate value XS at the point A. The Y coordinate value YS is also obtained in the same way.</p> |
