    • PROBLEM TO BE SOLVED: To provide a direct-drive positioning device having a motor and a slip-ring mechanism, by adapting an electrical connector means to transmit electric power, electrical signals, and the like carried by first wire means to second wire means via a rotary electrical coupling means.
      SOLUTION: Wires 8 connected at one end to brushes of a slip ring assembly 6 are connected at the other end to rotary rings of a slip ring assembly 9 within a shaft of a rotor 16 of a motor 10. Wires 11 connected to the brushes are connected at the other end to a camera 12 and a control circuit. By this arrangement, the camera 12 can limitlessly and continuously rotate centering around a panning axis H or a tilting axis V without causing wires to be twisted or deflected. A camera holding bracket 7 rested on a rotor 14 of a panning motor 2 is directly driven, while the rotor 16 of the tilting motor 10 directly drives the camera 12 to control its tilting position. Because of simplified structure, reliability, efficiency, and accuracy of a positioning device are improved.

    • 要解决的问题:为了提供具有马达和滑环机构的直接驱动定位装置,通过使电连接器装置通过第一线装置将电力,电信号等等传送到第二线装置,经由 旋转电耦合装置。 解决方案:一端与滑环组件6的电刷相连的电线8在另一端与电动机10的转子16的轴内的滑环组件9的旋转环连接。连接到电刷的电线11 另一端连接到照相机12和控制电路。 通过这种布置,相机12可以围绕平移轴线H或倾斜轴线V而不间断地连续地旋转,而不会使线材扭曲或偏转。 直立驱动静止在摇摄马达2的转子14上的相机支架7,而倾斜马达10的转子16直接驱动相机12来控制其倾斜位置。 由于结构简单,提高了定位装置的可靠性,效率和精度。
