3. A decimal-binary code conversion system according to claim 1, wherein ten key mechanisms are employed as magnetic field applying means, each being comprised of (a) a permanent magnet, (b) a pair of fixed yokes, arranged oppositely, at both ends of the permanent magnet, (c) a moving yoke which is disposed for movement relative to said fixed yokes with one end arranged in proximate relation to one fixed yoke and the opposite end is extended toward the other fixed yoke, and (d) a push button which is capped on the magnetic path so that the moving yoke is moved when the push button is depressed, and (e) at least one magnetro-resistance effect device which codes numerical values at the internal surface of the fixed yoke positioned opposite to one end of the moving yoke so that the magnetic flux which is applied to the device varies with the movement of the moving yoke.
4. A decimal code conversion system according to claim 3, wherein the moving yoke is a slider yoke.
5. A decimal-binary code conversion system having four amplifying circuits, said amplifying circuits comprising a. four code signal amplifiers; b. four magnetro-resistance effect devices connected to each of said amplifiers and arranged to provide each of the amplifying circuits with a bridge circuit, the four devices of each amplifying circuit consisting of
6. A decimal-binary code conversion system comprising a. four bridge circuits, each comprising four magnetro-resistance effect device and a pair of output terminals connected to said devices; b. four code signal amplifiers, each connected respectively to a different one of said pairs of said output terminals of said bridge circuits for emitting a code signal in response to an unbalance in the corresponding bridge circuit; and c. 10 field applying means adapted to selectively actuate said magnetro-resistance effect devices to cause unbalances in said bridge circuits, four of said field applying means each being adapted to change the resistance value of a given magnetro-resistance device in a different one of said bridge circuits, six of said field applying means each being adapted to change the resistance value of a magnetro-resistance device selected from each of two different bridge circuits, sid six field applying means being arranged to create unbalance in different combinations of said bridge circuits, whereby said amplifiers are adapted to indendently emit four different code signals and to collectively emit in pairs six other different code signals.
