Patent ID: 7770500

Claim:
A substrate cutting system, comprising: a mounting base having a substrate supporting device for supporting a substrate; clamp devices for holding at least one part of a side edge of the substrate carried-in on the table, the clamp devices reciprocating the substrate along the (Y) direction, the (Y) direction being along one side of the mounting base; a pair of substrate cutting devices for cutting both sides of the substrate, respectively; and substrate cutting device guide bodies, fixed to the mounting base facing each other, for moving each of the substrate cutting devices on a top surface side and a bottom surface side of the substrate in the (X) direction perpendicular to the (Y) direction, the substrate being moved in the (Y) direction by the clamp devices, wherein the substrate supporting device further includes first substrate supporting units and second substrate supporting units, the first substrate supporting units and the second substrate supporting units are apart from each other in the (Y) direction and arranged with the substrate cutting devices therebetween, and the first substrate supporting units and the second substrate supporting units support the substrate such that the substrate which has been moved in the (Y) direction by the clamp devices is cut along the (X) direction and the (Y) direction by the substrate cutting devices.
