PROBLEM TO BE SOLVED: To provide a scribing apparatus in which the hindrance of rotation of a blade caused by the accumulation of chips or the shortening of the life of the blade or the like are prevented. SOLUTION: The blade 8 is pressed onto the surface of a glass plate G at a prescribed pressing force by controlling the protrusion amount of a cylinder shaft 15 by selecting air pressure to an air cylinder 14, and air is blown in the blade 8 advancing direction side to the center of the blade 8 from air blowing port 22 of a holder 7 through an air supplying tube 11 and an internal air blow passage 12, and at the same time, air is blown toward a line connecting the rotation center of the blade 8 and the contact point of the blade 8 and the glass plate G from the advancing direction side of the blade 8 though an external air blow tube 17. Under such conditions, the glass plate G is cut by horizontally moving the head main body 2. COPYRIGHT: (C)2005,JPO&NCIPI
