COORDINATE DETECTING DEVICE USING ANGLE SENSOR

PROBLEM TO BE SOLVED: To obtain a coordinate detecting device which is usable as a teaching material for mathematics, physics, etc., by detecting position coordinates on a plane by using an angle sensor and using the coordinates in combination with a graph display electronic calculator, etc. SOLUTION: An arm A1 and an arm B2 are connected mutually movably on the angle sensor A(3) as a center axis and installed so that the angle that the arms A1 and B2 contain can be detected by the angle sensor A(3). Further, the arm B(2) can move a flat plate 5 on an angle sensor B4 as a center axis and the angle between the reference directions of the arm B2 and flat plate 5 can be detected by the angle sensor B4.
