A pivoting unit pivots a video camera at a pivoting speed. The video camera includes a zoom mechanism and a zoom amount signal generation circuit for generating a zoom amount signal. A pivoting speed command signal generating circuit responsive to an operation generates a pivoting speed command signal and a speed controlling circuit controls the pivoting speed in accordance with the zoom amount signal and the pivoting speed command signal. Controlling is made such that the pivoting speed is relatively decreased from the pivoting speed command signal when the zoom amount signal indicates a telephoto side and is relatively increased from the pivoting speed command signal when the zoom signal indicates a wide-angle. A joystick generating the pivoting speed command signal includes two coil springs for generating a reaction force which is made stronger when the operation angle of thereof exceeds a reference. The pivoting speed is also accelerated when the operation angle exceeds the reference.
