[0045] The glass-plate working apparatus 1 in accord- ance with this embodiment is comprised of: the base 3; the supporting table 4 which is provided on the base 3 and supports the glass plate 2; the transporting means 5 which is provided on the base 3 and transports the glass plate 2 in the X direction; the working head 7 for grinding the end face in the region R1 of one end face 6 ofthe glass plate 2; the moving means 10 for moving the working head 7 in the X direction along the end face in the region R1 of the glass plate 2; the working head 11 for grinding the end face in the regions R2 and R3 of the glass plate 2;the moving means12 for moving the work- ing head 11 in the X direction along the end face in the regions R2 and R3 of the glass plate 2;the working head 14 for grinding the end face in the region R4 of the glass plate 2; the moving means 17 for moving the working head14 in the X direction along theend face in the region R4 of the glass plate 2; the working head 18 for grinding the end face in the regions R5 and R6 of the glass plate 2;andthe movingmeans19 formoving the working head 18 in the X direction along the end face inthe regions R5 and R6 of the glassplate 2.Therefore, since theworking of the end face in the respective regions R1, R2, and R3 of the glass plate 2 can be effected by the working head 7 and the working head 11, and the working of the end face in the respectiveregions R4,R5,and R6 oftheglass plate 2 can be effected by the working head 14 and the working head 18, the efficiency of working with respect to the end facesoftheglassplate ishigh,and the working time ofthese operations can be shortened,thereby mak- ing it possible to carry out glass plate working with high productivity. 5 10 15 20 25 30 35 [0046] In the embodimentofthemethod ofworkingthe glass plate 2 by the glass-plate working apparatus 1 in accordance with this embodiment shown in Figs. 3 to 6, the following arrangement may be adopted. After the grinding ofthe end face in the region R1 oftheglass plate 2 by the working head 7, the moving stand 75 of the moving means 10ismovedin the Y direction by operating the servo motor78 ofthe cuttingamountadjusting means 64 of the moving means 10, so as to move the grinding wheel 25 of the working head 7 away from the end face 6 of the glass plate 2. Subsequently, by operating the servo motor 72 of the driving means 63 of the moving means 10, the grinding wheel 25 of the working head 7 is moved in the X2 direction from the working point A of the glass plate 2 in a state of noncontact with the end face in the region R1 of the glass plate 2. Meanwhile, after the grinding of the end face in the region R4 of the glass plate 2 by the working head 14, the moving stand 75 of the moving means 17 is moved in the Y direction by operating the servo motor 78 of the cutting amount adjusting means 64 of the moving means 17, so as to move the grinding wheel25 ofthe working head14 away from the end face 13 of the glass plate 2. Subsequently, 40 45 50 55 [0049] In addition, in the case where polishing is per- formed with respect to both end faces 6 and 13 of the glass plate 2 in the separate process, polishing may be performed with respectto both end faces 6 and 13 of the [0048] In this embodiment, after the grinding of both end faces 6 and 13 (the respective end faces in the re- gions R1, R2, and R3 and the regions R4, R5, and R6) of the glass plate 2, polishing may be performed with respect to both end faces 6 and 13 of the glass plate 2 in a separate process (online or offline) on the down- stream side 200 of the glass-plate working apparatus 1 in accordance with this embodiment. [0047] In the embodimentofthe method ofworking the glass plate 2 by the glass-plate working apparatus 1 in accordance with this embodiment shown in Figs. 3 to 6, the following arrangement may be adopted. After the grinding of the end face in the regions R2 and R3 of the glass plate 2 by the working head 11, the moving stand 75 of the moving means 12 is moved in the Y direction by operating the servo motor 78 of the cutting amount adjusting means 64 of the moving means 12, so as to move the grinding wheel25 ofthe working head 11 away from the end face 6 of the glass plate 2. Subsequently, by operating the servo motor 72 of the driving means 63 of the moving means 12, the grinding wheel 25 of the working head 11 is moved in the X1 direction from the working point A of the glass plate 2 in a state of noncon- tact with the end face in the regions R3 and R2 of the glass plate 2. Meanwhile, after the grinding of the end face in the regions R5 and R6 of the glass plate 2 by the working head 18, the moving stand 75 of the moving means 19 is moved in the Y direction by operating the servo motor 78 of the cutting amount adjusting means 64 of the moving means 19, so as to move the grinding wheel 25 of the working head 18 away from the end face 13 of the glass plate 2. Subsequently, by operating the servo motor 72 of the driving means 63 of the moving means 19, the grinding wheel 25 of the working head 18 is moved in the X1 direction from the working point B of the glass plate 2 in a state of noncontact with the end face in the regions R6 and R5 of the glass plate 2. In addition, an arrangement may be provided such that the respective grinding wheels 25 of the working heads 11 and 18 are not moved away from the end face 6 and the end face 13, respectively, of the glass plate 2, and are moved in the X1 direction by operating the respective servo motors 72 of the moving means 12 and 19. by operating the servo motor 72 of the driving means 63 of the moving means 17, the grinding wheel 25 of the working head 14 is moved in the X2 direction from the working point B of the glass plate 2 in a state of noncon- tact with the end face in the region R4 of the glass plate 2.In addition,an arrangementmay be provided such that the respective grinding wheels 25 of the working heads 7 and 14 are not moved away from the end face 6 and the end face 13, respectively, of the glass plate 2, and are moved in the X2 direction byoperatingtherespective servo motors 72 of the moving means 10 and 17. 8
