The present invention provides a coin feeding device that can separate coins of multiple denominations that are different in diameter. A rotary disk has a circular base plate and a pushing out disk with a plurality of space radial projecting portions extending above the circular base plate. The spaces between the radial projecting portions form coin separating concave portions for receiving coins. The circular base plate can have cam grooves. A pivoting moving body can be driven by the cam grooves and can be positioned at either a radially inward surface of the separating concave portion or extended forward to discharge a coin. One side of the separating concave portions are curved as a coin pushing portion while the other side has a protruding portion that is cantilevered to extend into the concave portion and to project upward to remove any extraneous coin that may be carried by movement of the rotary disk.
