Abstract

PURPOSE: To simplify the constitution of the peripheral circuits, to ensure the high- density input and output and thus to realize the extreme enhancement of the performance and the cost reduction, by carrying out the reading of the magnetic signal via two units of the magnetic resistance element applied with the DC bias magnetic field.
CONSTITUTION: U-shaped permanent magnets 3, 3 ... at magnetism detector part 1 are put adjacent to each other on the same plane and possess a pair of contrary pole faces. At the same time, magnetic resistance element M1 and M2 fixed on each pole face are connected in series with DC voltage Vin applied to both ends, and output terminal 4 is drawn out from the intermediate connection point. Magnetic card 2 formed with the permanent magnet sheets is magnetized in the thickness direction to form magnetic signal part 5 ... at each magnetization part, and the signal parts are arranged with the space almost equal to the space between magnets 3. And in case the areas corresponding to detector part 5 of card 2 are positioned at the N and S poles each, output signal (terminal 4) V- and V+ of (a) and (b) are supplied to comparator circuit 6 and then converted to the digital signals to be extracted through output terminal 7 in the form of the binary code signals.
