Pointer with a hollow shaft

摘要

The analog pointer instrument has a pointer device mounted on a rotatable shaft (4), an arrangement with which a light beam (6) can be coupled out from a source (7) and into the pointer device, a reflection element (11) that deflects the coupled in beam and a scale on which the deflected light beam causes a light appearance that forms an illuminated pointer. The coupled in light beam is passed through free space.
