PURPOSE:To simplify the construction and to increase the antiearthquake, by performing the control of two axes type to the antenna and three axes type to TV camera, and by fixing the pedestal at the center to the stand. CONSTITUTION:The antenna 1 and the TV camera 2 are mounted on the EL axis so that the weight around AX and EL is balanced. The EL axis 9 is fixexd to the console of the driver 3 via the bearings. Accordingly, the beam axis of the antenna 1 and the HR line of the TV camera 2 ,i.e.,light axis are parallel and keep a given distance. Further, the HR axis is made in agreement with the lengthwise direction of the console of the TV camera 2, the camera is turned around the HR axis with the driver mounted in the camera case to take a given location and to enable to catch the objective without tilt. Thus, the system is constituted with a maximum of three axes, the construction is simpler than conventional system constructions, the weight is light, and the control speed is increased. Since the system is fixed to the fastening stand 5 at the center of the pedestal 13, the antiearthquake performance is excellent. |
