摘要：
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.
