PURPOSE:To enable works for taking out a wafer carrier from a carrier box and for holding it in the vertical position to be carried out in one behavior, by providing a handle such that it can be mounted removably on the upper edges of the wafer carrier and that it can be held in the horizontal and vertical positions. CONSTITUTION:A handle 1 is mounted on a wafer carrier 7 by inserting arms 2, 2 between first and second ridges 7a, 7b provided on the upper edge of the side walls of the wafer carrier in parallel with each other and by fitting projections 6, 6 on the arms 2, 2 into recesses 7c provided in the first ridges 7a. When the handle 1 is raised up by means of a holder 4, the upper faces of the arms 2, 2 are abutted on the first ridges 7a, 7a. The wafer carrier 7 is thereby held horizontally. When the handle 1 is further moved up to a vertical position, the step faces of the projections 6, 6 are abutted on the step faces of the recesses 7c, 7c and the lower faces of projections 5, 5 are abutted on the upper faces of the second ridges 7b, 7b. The wafer carrier 7 is thereby held vertically. These functions are provided by the load of the wafer carrier which acts on the handle 1 as rotation moment M. |
