Claims

[Scope of utility model registration request]

A rotating body with a cord magnet that rotates in proportion to the weight being weighed.
A magnetic sensing element made of a ferromagnetic wire with uniaxial magnetic anisotropy and a relatively soft and hard coercive force is placed near this rotating body. A pulse electromotive force induced in the magnetically sensitive element is detected by the approach of the magnetic field generating source arranged to magnetize only the relatively soft part of the magnetically sensitive element in the opposite direction and the code magnet. A weighing device comprising a detection coil and a weighing display circuit activated by a pulse signal from the detection coil.
