The photo 5th from the bottom actually appears to be of a coin-operated rice mill!
The first time I saw one, I was probably ~6 years old and my grandfather stopped by on our way home to mill some of the rice he had grown. I was confused since growing up in the States, I had never seen non-white rice until that point.
It's actually quite enjoyable, as you get to run your fingers through warm rice pouring out from the machine.
