CONSTITUTION: A scribing unit with wheel/laser comprises a cylinder part(10), a post part(20), a holder part(30), and a scriber wheel. The cylinder part is stroked in a vertical direction by receiving external power. The post part is rotatable about a central axis in a vertical direction and strokes in a vertical direction by operating with the stroke of the cylinder part. The holder part is stroked in a vertical direction by being connected with the post part and rotates the post portion as a rotary shaft. The scribe wheel is detachable in the lower part of holder part, can integrally rotate with the holder part, and rotates the post portion as a rotary shaft. The scribe wheel forms an initial crack or scribing line in upper side of glass substrate.
