Interesting... it's listed on camerapedia!
It's a japanese subminiature camera that actually takes 14mm roll film!

Just imagine the 1950's at a christmas party:
-Honey, guess what it is.
-is it a camera?
-Yes honey.
-You didn't get me that minox I'd been dreaming about?
-No honey, I got you something even better
-Oh yeah! what is it? An Hasselblad?
-No honey, I got you a baby colon! Isn't it great!
