A Tiny Eraser Crumb Cleaner

Everyone has something that they cannot get enough of.
In my case, I love mechanical things, and I cannot help watching gears and linkages. To me, there was one thing I wanted for a long time. It was an eraser crumb cleaner. I saw it somewhere in Japan long ago. Since then, I wanted it. This product is undoubtedly my favourite among the items I bought in Japan this time.
Here it is.

Going to Japan this time was the best opportunity to get it.
However, even when I was in Japan, I could not find it in shops, so I searched it on the internet. I found a lot on the internet even though I could not find any at retail shops.

It is a tiny toy-like tool made with plastic. It costs about six dollars.
As it is even that small, it is well-made, and I am impressed.

On one side of the car, there are two tiny gears. As the rear tyres rotate, the smallest gear rotates and transmits power to the larger gear. The larger gear is connected to a zigzag bar. Two tiny brooms are linked to the bar, moving back and forth as the bar rotates. The movement is smooth, and it looks fun to watch.

I am not sure who invented it. At least, I guess that I saw it more than 15 or 20 years ago. It may not be very practical, but I love the idea of it.
I can only make something with timber, so making tiny things like this car is not easy. I wonder if I could someday make a small mechanical toy like this car.
