Measuring tape

摘要

The tape measure has a graduated (3) tape (2) with a hook (6) at the outer end. It is wound on a sprung drum contained within a case (8) which is formed from two half shells. The top shell has a large circular opening (12) with a window (13) which allows an inscription on the side of the drum to be viewed. The inscription may be produced by silk screen printing, laser engraving or auto-adhesion
