Stock unit for storing carriers

Claim 2

A stock unit for storing carriers comprising; a case-shaped unit body provided with storing racks to store carriers for carrying plate-like semiconductor wafers or liquid crystal substrates inside plural box-like compartments provided on said racks, said storing racks being piled in plural layers at a certain interval in said case-shaped unit body; carrier mounting ports on which said carriers that are to be placed in and out of certain box-like compartments in said racks are temporarily mounted; means for transporting said carriers between said box-like compartments and said mounting ports; and means for sending air in a direction parallel to the surfaces of said wafers or substrates when said carriers are placed on each of said box-like compartments, mounting ports and transporting means; wherein said air flows upwardly through the center of said storing rack and outwardly over the carriers, and said wafers are substantially horizontally disposed when the carriers are positioned within said box-like compartments and vertically disposed when the carriers are positioned on the mounting ports.

Claim 3

The stock unit for storing carriers according to claim 1, wherein the storing rack is shaped substantially like a disk and is rotatable within the case-shaped stock unit body.

Claim 4

A stock unit for storing carriers, comprising: a case-shaped unit body provided with storing racks to store carriers for carrying plate-like semiconductor wafers or liquid crystal substrates inside plural box-like compartments provided on said racks; mounting ports on which said carriers that are to be placed in and out of certain box-like compartments in said racks are temporarily mounted; means for transporting said carriers between said box-like compartments and said mounting ports; and means for sending air in a direction parallel to the surfaces of said wafers or substrates when said carriers are placed on each of said box-like compartments, mounting ports and transporting means; wherein said air flows upwardly through the center of said storing rack and outwardly over the carriers, and said wafers are substantially horizontally disposed when the carriers are positioned within said box-like compartments and vertically disposed when the carriers are positioned on the mounting ports.

Claim 5

A stock unit for storing carriers, comprising: a case-shaped unit body provided with storing racks to store carriers for carrying plate-like semiconductor wafers or liquid crystal substrates inside plural box-like compartments provided on said racks; mounting ports on which said carriers that are to be placed in and out of certain box-like compartments in said racks are temporarily mounted; means for transporting said carriers between said box-like compartments and said mounting ports; and means for sending air in a direction parallel to the surfaces of said wafers or substrates when said carriers are placed on each of said box-like compartments, mounting ports and transporting means; wherein said air flows upwardly through the center of said storing rack and outwardly over the carriers, and said wafers are substantially horizontally disposed when the carriers are positioned within said box-like compartments and vertically disposed when the carriers are positioned on the mounting ports.

Claim 6

The stock unit for storing carriers according to claim 3, wherein said storing racks are piled in plural layers at a certain interval in the case-shape stock unit body.

Claim 7

The stock unit for storing carriers according to claim 3, wherein the storing rack is shaped substantially like a disk and is rotatable within the case-shaped stock unit body.

Claim 8

A stock unit for storing carriers comprising: plural case-shaped unit bodies provided with storing racks to store carriers for plate-like semiconductor wafer or liquid crystal substrates inside plural box-like compartments provided on said racks and piled in plural layers at a certain interval; plural mounting ports on which said carriers that are to be placed in and out of certain positions on desired storing racks are temporarily mounted and which are arranged to correspond to certain positions on said desired storing racks; means for transporting said carriers between certain positions on said desired storing racks and the mounting ports; and means for sending air in a direction parallel to the surfaces of said wafers or substrates when said carriers are placed on each of said box-like compartments, mounting ports and transporting means; wherein said air flows upwardly through the center of said storing rack and outwardly over the carriers, and said wafers are substantially horizontally disposed when the carriers are positioned within said box-like compartments and vertically disposed when the carriers are positioned on the mounting ports.

Claim 9

A stock unit for storing carriers comprising: plural case-shaped unit bodies provided with storing racks to store carriers for plate-like semiconductor wafer or liquid crystal substrates inside plural box-like compartments provided on said racks and piled in plural layers at a certain interval; plural mounting ports on which said carriers that are to be placed in and out of certain positions on desired storing racks are temporarily mounted and which are arranged to correspond to certain positions on said desired storing racks; means for transporting said carriers between certain positions on said desired storing racks and the mounting ports; and means for sending air in a direction parallel to the surfaces of said wafers or substrates when said carriers are placed on each of said box-like compartments, mounting ports and transporting means; wherein said air flows upwardly through the center of said storing rack and outwardly over the carriers, and said wafers are substantially horizontally disposed when the carriers are positioned within said box-like compartments and vertically disposed when the carriers are positioned on the mounting ports.

Claim 10

The stock unit for storing carriers according to claim 6, wherein the storing rack is shaped substantially like a disk and is rotatable within the case-shaped stock unit body.
