A drive controller of an operating machine configured to drive a structure by a hydraulic motor 2 and an electric motor 3 includes: a remote control valve 5 configured to determine the operation amount of the structure; an electric motor torque calculation portion configured to calculate torque of the electric motor 3; a hydraulic motor torque calculation portion configured to calculate torque of the hydraulic motor 2; a controller 7 configured to transmit an opening position control signal to the control valve 14 based on the operation amount determined by the remote control valve 5 such that torque necessary to drive the structure is obtained from the torque of the electric motor 3 and the torque of the hydraulic motor 2; and solenoid-operated reducing valves 19 and 20 each configured to reduce a pilot pressure, to be applied to the control valve 14, based on the opening position control signal output from the controller 7.
