That is, there is provided a step having a height corresponding to the curved surface of the plate material W curved in a convex shape that is conveyed.

With the above configuration, when the plate material W bent in a convex state and conveyed is placed on the mounting table 47, the height of the plate material receiving arm 51 becomes a height corresponding to the curved surface of the plate material W. Therefore, the plate material W is placed in a curved state. Therefore, the plate material W itself becomes rigid, and the plate material W placed on the plate material W can be supported by a small number of mounting bases 47 without sagging.

Further, referring to FIG. 12, this embodiment shows a fifth embodiment, and the plate material W in the above-mentioned first embodiment is used.

Further, in the first embodiment, the vacuum pad 13A, 13B, 13C is used as the suction member 13 to suck and lift and convey the plate material W, but the vacuum pad 13B may be pushed without any suction action. Further, in the second embodiment, the suction member 25
