摘要:
A coordinate input device with display includes a tablet having a plurality of parallel X-direction magnetostrictive transmission mediums, a plurality of parallel Y-direction magnetostrictive transmission mediums superposed on, and substantially orthogonal to the X-direction mediums thereto, and first and second coils wound around the magnetostrictive transmission mediums. The device further includes a plurality of biasing magnetic means for applying a biasing magnetic field to portions of the magnetostrictive transmission mediums surrounded by the first and second coils, and a tabular display superposed on the tablet and having a display area substantially equal to the position detection area on the tablet. A magnetic pen is used to cause a local increase of electro-mechanical coupling coefficient in the magnetostrictive transmission mediums in the tablet. The device further has an apparatus for recording in hard copy form the data corresponding to the appointed coordinate values, made by the magnetic pin on the display and can be visually checked.
