A code translation device for translating an information character into a binary signal, comprising a drive circuit for supplying current to an exciting coil wound on a magnetic core, and variable impedance means varying the amount of drive current supplied to the exciting coil and including a control coil wound on a second magnetic core to constitute high impedance to limit the amount of drive current supplied to the exciting coil to a small amount to provide four parallel O output signals to indicate an idle state at one time and thereafter to constitute a low impedance to increase the amount of drive current supplied to the exciting current to provide four parallel 1 and 0 output signals to represent a preselected information character at another time.
