Claim:
A storage, comprising: a supporting portion configured to support a load, the supporting portion being a putting portion having a first putting surface configured to support said load from a bottom side of said load; a horizontal driving portion configured to move said supporting portion back and forth in a first horizontal direction; a vertical driving portion configured to move said supporting portion back and forth in a vertical direction; a rack having a plurality of second putting surfaces each configured to transfer said load mutually with said first putting surface of the supporting portion, said rack having only one line in another horizontal direction, said second putting surfaces being disposed at a plurality of stages in the vertical direction at which said supporting portion can access each of the second putting surfaces by said horizontal driving portion, at least one of said second putting surfaces being disposed at a horizontal position at which said supporting portion can access the at least one of said second putting surfaces by said horizontal driving portion, at least one of said second putting surfaces being located at a top stage of said stages in said rack functioning as a port to unload and load said load with a transporting carriage which travels along a track and moves the load down and up in the vertical direction below the track, said first putting surface of the putting portion additionally functioning as said port with the at least one of said second putting surfaces; a first putting line in which at least some of the second putting surfaces are located in the first putting line in the vertical direction, the second putting surfaces of the first putting line located at the top stage of said stages functioning as the port; a moving line in which the load is moved back and forth in the vertical direction by the vertical driving portion; and a second putting line in which at least some other second putting surfaces are located in the vertical direction and which does not include the port, wherein the first putting line, the moving line, and the second putting line lie next to one another in the first horizontal direction, and an azimuth of the first horizontal direction intersects perpendicularly to an azimuth of the track.
