Abstract
A marking apparatus is provided having a wheel with a plurality of radial slots for receipt of stamps having marking indicia thereon. An internal axially rotatable disc has a cam engageable with the stamp ends causing selected ones to protrude from the wheel periphery. A slot in the disc receives a lateral extension from each stamp for retaining them in retracted position. A segment of the slot adjacent the cam curves radially outward to allow the stamp contacted by the cam to slide outward and protrude from the wheel.
