Abstract
In a scanning densitometer the mobile head is connected by means of an optical fiber cable with stationary parts of the apparatus. The optical fiber cable is looped around a cable drum and guided by it. The cable drum is suspended by means of two supporting cord layouts looped around it in opposing directions in a rotating manner parallel to the linear path of motion of the measuring head. The supporting cord layouts are mounted stationarily on the apparatus and one of them contains an equalizing spring. This type of a cable conduit is highly protective and therefore particularly suitable for mechanically sensitive parts, such as for example, optical fiber cables.
