PROBLEM TO BE SOLVED: To reduce the numeric variables of a monitor display without extremely lowering the control precision of automatic control, and to easily recognize a monitor numeric value in a signal processor and the monitor display for construction machinery. SOLUTION: The first and second filter processing arithmetic sections 9d and 9e are installed on a control unit 9, the low-pass filter processing of comparatively high cutoff frequency (such as 10 Hz) for control aiming at the elimination of a noise component is conducted to the numeric data of the position and posture of a front working machine 1A by the first filter processing arithmetic section 9d, the low-pass filter processing of comparatively low cutoff frequency (such as 1 Hz) for a display aiming at the prevention of a numeric variable in the monitor display is conducted by the second filter processing arithmetic section 9e, former processing data are used in control operation, and latter processing data are output to the monitor display 7 for a setter 7, and displayed to indicators 7c and 7d at numerals.
