<p>The present invention relates to a marking system. The invention provides the marking system, comprising: a guide rail parallel to a first direction; a first support unit coupled to the guide rail to be movable in the first direction along the guide rail or in a second direction opposite to the first direction; a second support unit coupled to the first support unit such that a distance away from the first support unit is variable; a marking unit having at least one roller in contact with a surface of a marking object and coupled to be rotated around one point of the second support unit as a shaft so as to mark information on the surface of the marking object; and a driving means for moving the first support unit forward or backward along the guide rail wherein the marking system performs a marking operation while maintaining a predetermined distance from the surface of the marking object and thereby becomes capable of uniformly marking a variety of information on the surface of the marking object.</p>
