Abstract

A digitizer with a cordless cursor to input coordinates of graphics is described. The digitizer utilizes magnetostrictive delay lines made of iron-base amorphous ribbons. During propagation of the magnetoelastic wave in the ribbon, the output signal is generated by a solenoid coil wound through the entire ribbon length when the wave arrives at a position immediately underneath the cursor magnet. Resolution of the above position was 0.1 mm, and a high cursor position of 12 mm was realized
