Abstract
The identification structure includes: a bottom plate screwed to the undersurface of a container body in which wafers are stored in alignment; a multiple number of passage holes bored in the bottom plate at identification areas thereof; and identification pieces to be selectively fitted to the multiple number of passage holes. The identification piece assumes a bottom-closed cylinder in which a pair of flange portions extend radially outward in all directions from the whole peripheral wall of the bottom-closed cylinder, at one and the other hollowed open ends so as to abut the periphery of the passage hole and that the flange portion at the hollowed opening end tapers from one end near to the closed end towards the other hollowed open end, forming an inclined insert surface. This bottom-closed cylinder can be fitted from either above or below the bottom plate. In this arrangement, the information about a substrate storage container is obtained based on the set mode of the identification piece.
