PURPOSE: To prevent the drop of articles on a tray while the tray is carried and to facilitate the ejection of articles from the tray by providing a wall on the peripheral part of a baseplate and making an inclined face in the part of the baseplate.
CONSTITUTION: A wall 102 which is low in height is provided on the all the peripheral parts of a square baseplate 101. In the half of the baseplate 101, an opening is provided, and a conver state baseplate 103 which fits the opening is coupled with the baseplate 101 in a hinge part 104. In a delivery tray 100, the cover state baseplate 103 which occupies about the half of all the area of the baseplate is capable of bending toward the upper direction from the center of the baseplate and an inclined face can be formed toward the wall 102 from the center of the baseplate 101. In this constitution, articles do not drop below the tray 100 because the wall 102 is provided on the peripheral part of the baseplate 101. When articles are ejected from the tray 100, the ejection of the articles is smooth because the articles go up along the inclination made of the part of the baseplate 101, they get over the wall 102 and they are ejected to the outside of the tray 100.
