#2315: DuoNote

I like postit notes very much but I’m sometimes in need of a way to make an exact copy of the contents of one note.

In the old days, a piece of carbon paper might have sufficed, but it’s pretty messy stuff and the resulting copy quality can be poor.


Today’s invention offers an alternative.

A (ferrous-nibbed) pen is equipped with a thin magnetic disc.

As the pen writes on the top note, so this disc is moved on top of the next one.

A small roller ball (attached to the underside of the disc and impregnated with ink) follows the pen nib and creates a duplicate image on the second note.
