From Wikipedia: "The Geneva drive or Maltese cross is a gear mechanism that translates a continuous rotation into an intermittent rotary motion"
So this is not a Geneva Wheel because it transmits continuous rotation. :)
The book I found this in describes it as follows:
"Multiple Gearing" - a recent invention. The smaller triangular wheel drives the larger one by the movement of its attached friction rollers in the radial grooves
