DEVICE OF BREAKING BRITTLE MATERIAL SUBSTRATE

摘要

PROBLEM TO BE SOLVED: To provide a device of breaking a brittle material substrate capable of breaking the substrate vertically from a scribe line.SOLUTION: Receiving blades 54A and 54B are rotatably fixed above a pair of support members 53A and 53B mounted to be movable with a minute interval. The receiving blades are closed, and a substrate 40 is arranged so that a position of the substrate 40 is adjusted to a scribe line 43. The substrate 40 is pressed by a blade 23 from above. Thus, the receiving blades move rotationally mutually in opposite directions, and the substrate 40 can be broken in a cross section perpendicular to the scribe line.
