時に発生した塵埃が下段に保管した物体に落下し
て付着し、前記した問題と同様に、塵埃による
種々の問題を発生していた。 Conventionally, when storing dust-free objects in a clean room or a clean bench in a space-efficient manner, it has been common to use a storage shelf with a plurality of shelves installed in the height direction. Therefore, if each shelf is made of air-impermeable plates, the clean air in the downward laminar flow will not flow into each shelf, resulting in a low level of air cleanliness within the storage shelf, and the objects being stored will This caused various problems due to dust.
In addition, when each shelf is constructed with a net-like plate that allows air to pass through, clean air in a downward laminar flow is introduced into the storage shelf, but the dust generated when moving objects stored on the upper shelf is transferred to the lower shelf. Dust particles fall onto objects stored in the room and adhere to them, causing various problems similar to those described above.
この発明の目的は係る塵埃の問題を発生させ

事である。 An object of the present invention is to provide a storage shelf that does not cause the problem of dust and can be stored space-efficiently in a clean room or clean bench.

管棚にある。 A feature of the present invention is that in a storage shelf provided with a plurality of shelves in the height direction in order to store objects that do not like dust in a clean room or a clean bench in a space-efficient manner, a laminar flow is generated downward from the upper part of the shelf. The storage shelf has a place for introducing clean air and supplying it to each of a plurality of shelves, and has a structure in which the positions of the plurality of shelves in the height direction are recessed from the top to the bottom.

ない。 Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a sectional view of a storage shelf for explaining an embodiment of the present invention. The storage shelf of this embodiment has four shelves, shelf 1 to shelf 4, in the vertical direction, and openings 5, 6, 7, and 8 are provided in the upper part of each shelf. In other words, when this storage shelf is installed in a clean room with a downward laminar flow system or a clean bench, clean air flowing from above to below passes through the openings 5, 6, 7, and 8 at the top and reaches each shelf. Air flows out from the front surface of the shelf through the provided inclined plates 9, 10, 11, and 12, and the cleanliness of the space above the shelves 1 to 4 is maintained. Also, from the upper shelf 1 to the lower shelf 2 to 4
Since it has a structure that is concave to the back as the noise is heard, dust generated when objects 13 stored on the upper shelf 1 are moved does not enter the lower shelves 2 to 4.
又、保管棚上部に強制的に風を送られる三角屋
根１４を設ける事により、保管棚１〜４内の清浄
度は更に改善される。 Furthermore, by providing a triangular roof 14 above the storage shelf through which air is forced to flow, the cleanliness inside the storage shelves 1 to 4 is further improved.
本実施例によれば、従来仕様の保管棚最下段の
塵埃のレベルが、24時間塵埃測定の結果、無数の

体に付着する塵埃の問題を防げる事が解つた。 According to this example, the dust level at the bottom of the storage shelf in the conventional specification was found to be countless dust particles as a result of 24-hour dust measurement, whereas in the same measurement at the bottom of the storage shelf in this example, This can be reduced to a level of 10 to 15, and in this example, in a downward laminar flow clean room or clean bench,
It has been found that objects can be stored cleanly with space efficiency and the problem of dust adhering to objects can be prevented.
尚上述の実施例において、棚の数・形状は自由
