Pen type scanner

When I read a book, I usually have a pen and draw lines to the book with a pen for make deeper my understanding of the book.
And lines drawn by me should be transcribe on PC or my notebook. This work is dobule work.

But a tool I found may solve this problem.
It is "Quicktionary Ⅱ"*1.

The tool which seems to be some kind of pen can send texts on a paper by scanning and translate texts to desired languege if I want.

This is great job!!
So I want to buy the tool. But the tool costs tens of thousands of Yen.
Woom :-(
