Assembly pin for notice board with rotary elements

摘要

The assembly pin (11) is made from a rigid material and designed to pass through rotary supports of panel modules which are set to give out a given message. Each pin has male and female sections (2, 3) which allows it to be joined together with others to form a rigid and graduated structure. The notice board has a self-correcting electronic system and command matrices, a colour selector and optical reader.
