Patent ID: 7676937

Claim:
A scribing head comprising: a scribing line forming means structured so as to form a scribing line on a substrate; and a moving means for moving the scribing line forming means such that the scribing line forming means presses the substrate with a constant magnitude, wherein the moving means includes: a rotation means rotating about a rotation axis, the axial center of the rotation axis being provided so as to align with a predetermined direction in which the scribing line forming means moves, wherein the substrate is pressed upon moving the scribe line forming means to the direction of the substrate and providing a positive rotation of the rotary shaft of the rotational means, and moving by forcing back to the direction of the rotational means, thereby reversely rotating the rotary shaft of the rotational means, and a motive power transmission means for transmitting a motive power between the motive power transmission means and the scribing line forming means such that the scribing line forming means moves on a straight line along the axial center of the rotation axis in response to the rotation of the rotation means, the motive power transmission means being provided along the predetermined direction.
