The first zero point bolt 258a and the second zero point bolt 258b are normally in contact with each other and the pusher bracket 252 is lowered together with the extension bracket 251 so that the vacuum pad 255 is fixed to the stick- The lowering of the pusher bracket 252 is stopped when the first and second zero point bolts 258a and 258b are separated from each other. Accordingly, when the first and second zero-point bolts 258a and 258b are separated, the zero point position at which the vacuum pad 255 is in close contact with the glass substrate G can be identified. 240 control the degree of descent of the extension bracket 251. That is, by employing the first and second zero point bolts 258a and 258b, the degree of descent of the extension bracket 251 can be accurately controlled. Therefore, the extension bracket 251 is excessively lowered, G can be prevented from being damaged.

It is preferable that one of the first and second zero point bolts 258a and 258b has a circular shape and the other has a flat shape.

The position detection sensor 259 measures the position of the glass substrate G by sensing the positions of both side ends of the stick-shaped glass substrate G as shown in Fig. By adopting such a position sensing sensor 259, the distance of the pusher unit 250 conveyed by the horizontal feed driving unit 230 is limited by the length of the stick-shaped glass substrate G.
