Mark e.g. line-mark, indicating device for use in industrial area, has support units performing rotatable movement around rotation axis that is formed perpendicular to pre-determined shifting direction during indication of mark

摘要

The device has blocking units (1, 2) at which blocking surfaces (1a, 2a) are formed, where distance of the surfaces is changed. A retainer (6) for the accommodation of indication units (7) is formed in support units (3, 4), which are rotatably supported in an area of end sections (3a, 4a) so that the support units perform a rotatable movement around a rotation axis during changing of distance between the surfaces. The axis is formed in the blocking units and is formed perpendicular to a pre-determined shifting direction of the blocking units during indication of a mark.
