Here, mounting and stacking of plate-like objects according to an example of a conventional tray will be briefly described with reference to FIG.
As shown in FIG. 5A, the frame portion 120 is an overlapping portion and a bottom portion (support portion) 130 on which a plate-like object is mounted. The bottom portion (support portion) 130 is fixed to the frame portion, and the frame portion. It is a strong plate-like material that covers the entire region of the frame 120, and even if a plate-like object is mounted horizontally on it, it does not bend due to its own weight.
In the case of this conventional tray, for example, a plate in which a plate-like object is mounted on the bottom 130 in a horizontal state is sequentially stacked on the frame (FIGS. 5A to 5C), and the plate Two trays on which the objects are mounted are overlapped (FIG. 5 (d)) and tripled (FIG. 5 (e)).
In this way, the desired number of stacks is obtained, but in this conventional tray, the plate-like object is just mounted on the bottom, and is displaced by vibration during transportation, so that the functional surface comes into contact. In some cases, the ends may be damaged due to scraping or dust may be generated, resulting in quality problems.
On the other hand, in each of the first to sixth examples and the first embodiment , the plate-like object is lifted due to vibration during conveyance or the like because it is mounted in a bent state on the lower side in the vertical direction. Can be reduced, and such quality problems can be eliminated.

The present invention is not limited to the first to sixth examples .
For example, the curved shape of the plate-like object holding portion is a circular shape, a partial shape of a polygon or an ellipse, or a shape in which a part of the outer shape of an arc or an ellipse is combined with a straight line. Also mentioned.
Further, in the first example to sixth example of, but not explicitly a positioning mechanism comprising a positioning when stacking tray, for example, provided on the front and back of the frame positioning portion of the uneven shape to be fitted to each other Keep it.
Alternatively, a mechanism for locking the position is provided in the frame portion.
