PURPOSE:To turn a TV camera in a prescribed direction easily by providing a preset controlling means of controlling a camera position setting means, and a step driving controlling means. CONSTITUTION:For preset control using an operation signal from an operating device 9, when a preset swivel position of a motor-driven tripod head 5 is selected, its signal is transmitted through a narrow-band transmission line 10b to a preset position selecting circuit 13, which is put in operation. Then, the output of the circuit 13 is supplied to a switching circuit 15 and a driving relay circuit 6 to turn the tripod head to a prescribed preset position. When the tripod head 5 stops at the prescribed position after the movement, a signal from a TV camera 1 is transmitted through a narrow-band transmission line 10a to a TV monitor by a control signal from a still picture transmission control circuit to be displayed thereupon. To swivel the tripod head 5 from the preset position, stepwise driving control is selected by the operating device 9, and then its control signal is transmitted through the transmission line 10b, so that a stepwise driving signal generator 16 swivels the tripod head 5 by stepwise driving. |
