<p>Disclosed is a glass sheet processing apparatus, which relatively moves a cutter (30) and a glass sheet (40), said cutter being connected to one end of an air cylinder (10) with a holder (20) therebetween, in a state wherein the cutter (30) is in pressure-contact with the glass sheet (40), and which processes a cutting line (42) on the glass sheet (40). The air cylinder (10) has a cylinder main body (11), a piston (12) that can reciprocate in the cylinder main body (11), and first and second pressure chambers (14, 15), which are demarcated on both the sides of the piston (12). The atmospheric pressure in the first and the second pressure chambers (14, 15) can be independently controlled, and the pressure chambers are communicated through a space (17) between the inner circumferential surface (114) of the cylinder main body (11) and the outer circumferential surface (122) of the piston (12). A groove (18) is provided on the inner side of the outer circumferential surface (122) of the piston (12).</p> |
