The glass plate holding table device adsorbs and fixes the glass plate on the upper surface, and also holds the glass plate holding table so that it can be freely rotated. It consists of a table holding and driving device to be performed, and is erected from the base on this table holding and driving device. On the other hand, the folding device holds the folding portion of the outer peripheral edge of the glass plate from the front and back surfaces of the glass plate. A folding plate body having a glass plate gripping portion and a tilting drive device for lowering the glass plate gripping portion while keeping the glass plate gripping portion away from the glass plate holding table; An advancing / retreating device for advancing / retreating with respect to the plate holding table. The advancing / retreating device is installed on a guide rail device standing from the machine table toward the glass plate holding table, and is held by the guide rail device. The slider comprises: a slider that moves forward and backward relative to the glass plate holding table; a feed screw device that is connected to the slider and advances and retracts; and a servo motor that is connected to the feed screw device and drives the feed screw. A bracket protrudes downward, and the splitting tool body is mounted on the bracket, and the gripping body of the splitting tool body is attached to the bracket so that it moves away from the glass plate holding table from the top to the bottom. Attached to the plate attached to the slider of this slide device. In addition, the tilt drive device is mounted on the bracket, and the tilt drive device is composed of a telescopic portion whose tip portion projects and retracts and a telescopic drive body which projects and retracts the telescopic portion, and is driven by telescopic drive. When the expansion / contraction part of the body is connected to the opening / closing drive main body of the gripping device, and the gripping device grips the outer peripheral edge split portion of the adsorption glass plate with the glass plate holding table, the expansion / contraction part of the opening / closing driving body is While projecting and moving away from the glass plate holding table while lowering the gripping device, the glass plate folding portion is bent and bent so as to rotate around the pinning portion to be inclined. A glass plate processing device that is separated.
