Abstract
In an electron beam control system wherein manual adjusting means is used for adjusting currents to flow through two deflection coils which serve to deflect an electron beam in directions of two, x and y axes, respectively; an electron beam control system wherein the manual adjusting means comprises a joy stick type variable resistor which can simultaneously deliver coil deflection signal components in the directions of the two axes through a single operation, and the signal components from the variable resistor are applied to the corresponding deflection coils as adjusting currents.
