Реферат: The ruler has the hollow holder for the drawing implement formed integrally with it or selectively attached to it, the holder also acting as a hand grip for steadying the ruler. Pref. the holder comprises a tube which can be closed at both ends and which extends across the top face of the ruler parallel to the scale indication marked along one or both of its elongate edges, as printed or engraved characters, of differing colours and/or size. The holder may be attached to the ruler by a clip running along its length which fits over one of the elongate edges of the ruler, or over a profiled ridge running along the central part of the ruler. Both the ruler and the holder may be of plastics.
