Abstract
A magnetic type digital-analogic position-sensing device utilizes plural magnetic strips and plural digital sensing readers to perform position-sensing operation. One of the magnetic strips is provided with an analogic sensing reader. After being finely divided, the signal outputted from the analogic sensing reader can cooperate with the signals outputted from the digital sensing readers to obtain the displacement of the sensor. By such arrangements, the position-sensing device can both have high environment adaptability and high resolution.
