Abstract: A scanning unit adapted for scanning a measuring graduation of a scale for purposes of position measurement in a measurement direction includes a housing having a detector configured to generate position-dependent scanning signals. An electrical lead passes out through the housing in the measurement direction. A rotatable member, in which the electrical lead is routed, has a first section extending in the measurement direction and a second section extending in a second direction at an angle relative to the measurement direction. The rotatable member is rotatably mounted on the housing about an axis of rotation extending in the measurement direction.

Abstract: A method for installing a measuring tape on a circumferential surface of a holder. The method including wrapping the circumferential surface of the holder with the measuring tape and bracing the measuring tape such that the measuring tape extends spaced apart from the circumference of the holder. When the measuring tape extends spaced from the circumference of the holder due to the bracing, exerting a tensioning force on the measuring tape so that the measuring tape is held with low friction above the circumference, wherein the tensioning force is distributed at least nearly uniformly over the circumference. The method includes undoing the bracing of the measuring tape beginning at a fixation point at which a portion of the measuring tape is affixed to the circumferential surface. The method also includes applying the measuring tape to the circumferential surface of the holder while maintaining the tensioning force.

Abstract: A scanning system of a position measuring device for photo-electric scanning of a measuring graduation, the scanning system including a support carrying measuring components, an adapter including a scanning graduation in a graduation plane and a holder that holds the support on the adapter. The holder is structured so that the support is stationarily positioned on the adapter in six degrees of freedom, but compensates thermally caused expansion of the support in relation to the adapter in a first coordinate direction and a second direction which define the graduation plane.

Abstract: A securing arrangement for transporting and mounting a measuring system used for the determination of the position of two components, which can be moved relative to each other. The securing arrangement includes a base body, which is linearly displaced along a displacement direction via a guide track of a support body of a measuring graduation of the measuring system and is fixed in place on the support body by clamping forces in order to maintain a mounting base that fastens a scanning device to one of the two components in a desired position in relation to the support body. A service element is provided on the base body and having an operating section for introducing and/or canceling the clamping forces, wherein the operating section of the service element laterally protrudes past a surface of the base body which faces away from the support body and is laterally bordered by a lateral edge, when the base body is fastened on the support body.
