<p>This object selecting device is provided with a container which has an inside bottom part and which stores a liquid, a plate which has a top surface and a bottom surface, which is immersed in the liquid, and which supports the objects to be selected, and a holding means which holds the plate in a state in which the bottom surface of the plate and the inside bottom part of the container are spaced apart. The plate has through-holes at the support positions, and the through-holes have a tapered portion allowing the objects to be selected to settle in the direction of gravity and to be supported through contact with the inner wall surfaces of the through-holes, wherein the opening area at the top end of the tapered portions is larger than the opening area at the bottom of the tapered portions. From a set of objects of different shapes, only the objects to be selected will be supported by the tapered portions, and non-selection objects will settle into the inner bottom part of the container. Further, when removing the objects to be selected that are supported, since the plate is spaced apart from the inner bottom part of the container by the holding means, non-selection objects that have settled to the inner bottom part will not be erroneously removed.</p> |
