Abstract: To allow data from the joy stick type operation levers to be output to the main control section side using a minimum number of output wires, a joy stick type operating lever is provided with a sub-control section which receives signals from the joy stick and other related sources, digitizes and arranges the signals according to a present order and outputs the signals to a main control circuit.

Abstract: A device for controlling an engine includes a main control unit for outputting a control signal in response to a signal from an accelerator dial, and a sub-control unit for controlling an actuator that actuates a control lever of a fuel feeding device in response to a control signal from the main control unit and a signal from a key switch. The sub-control unit controls the actuator in response to an off signal from the key switch so that the control lever is moved to a fuel stop position and, after the operation of the engine has been halted, controls the actuator so that the control lever is moved to a start position.

Abstract: An actuator for an accelarator includes a casing and a driving part having a reversibly revolvable motor disposed in the casing, a decelerator for decelerating revolution of the motor, and an output pulley, connected to the decelerator, for taking up or letting out a control cable cable. The actuator also includes a control part composed of an operation part, and a control mechanism for controlling the revolution of the motor on the basis of a deviation between a position of the operation part and a position of the output part,wherein the driving part and the control part are integrally coaxially connected to each other.
