  Next, an operation when the substrate W is stored in the substrate storage space 27 will be described. First, all the upper latch portions 32A and the lower latch portions (not shown) of the lid body 3 are not protruded from the upper and lower sides of the lid body 3, and the lid body 3 is opened to the peripheral edge portion 28 of the container body 2. Remove from. Next, each of the 25 substrates W is placed on the substrate support plate-like portion 5 so that the 25 substrates W are supported by the substrate support plate-like portion 5. Next, the lid 3 is brought into contact with the opening peripheral edge 28.

At this time, the front edge W4 of the back surface W2 of each substrate abuts on the front retainer second contact surface 734 of each front retainer 7 and is pushed in the rear direction D12. As a result, as shown in FIG. 7A, the rear edge W4 of the back surface W2 of each substrate W abuts on the second abutment surface 631 of the wall substrate support 60, and the second abutment surface 631. Glide up. The rear edge W3 of the front surface W1 of each substrate W is in contact with the first contact surface 621 of the wall substrate support 60. Further, the edge W3 of the front surface W1 and the edge W4 of the back surface W2 of the substrate W push the first contact surface 621 and the second contact surface 631 in the rear direction D12, respectively, so that FIG. As shown, the first leg portion 65, the second leg portion 66, the first plate portion 62, and the second plate portion 63 are elastically deformed, and the substrate W is formed by the first contact surface 621 and the second contact surface 631. The rear edges W3 and W4 are sandwiched.
Similarly, the front portion of the edge W4 of the back surface W2 of each substrate W slides on the front retainer second contact surface 734 of the front retainer 7. The front portion of the edge W3 of the surface W1 of each substrate W is in contact with the front retainer first contact surface 733 of the front retainer 7.

  Accordingly, the rear portions of the edges W3 and W4 of the plurality of substrates W are supported by the wall substrate support portion 60 of the rear retainer 6, and the front portions of the edges W3 and W4 of the edges of the plurality of substrates W are The front retainer 7 is supported by the front retainer substrate receiving portion 73 of the front retainer 7. That is, the wall substrate support part 60 cooperates with the front retainer substrate receiving part 73 of the front retainer 7 to separate the edges of the plurality of substrates W from the substrate support plate-like part 5, so that adjacent substrates W are separated from each other. A plurality of substrates W are supported in a state of being spaced apart by a predetermined interval and in a state of being parallel to each other.

  Next, the lid 3 is fixed to the opening peripheral portion 28 with all the upper latch portions 32A and the lower latch portions (not shown) of the lid 3 protruding from the upper and lower sides of the lid 3. Then, the container body opening 21 is closed with the lid 3. Thus, the 25 substrates W are stored in the substrate storage space 27.

According to the substrate storage container 1 according to the first embodiment having the above configuration, the following effects can be obtained.
As described above, the substrate storage container 1 is disposed so as to be paired with the lid-side substrate support portion (front retainer substrate receiving portion 73) in the substrate storage space 27, and can support the edges of the plurality of substrates W. Yes, when the container body opening 21 is closed by the lid 3, the edges of the plurality of substrates W are moved to the side substrate support in cooperation with the lid side substrate support (front retainer substrate receiving portion 73). A back side substrate support portion (wall portion substrate support portion 60) that supports the plurality of substrates W is provided in a state of being separated from the (substrate support plate-like portion 5) and arranged in parallel.

  The rear substrate support portion (wall substrate support portion 60) includes a leg portion 64 that can be elastically deformed and a substrate receiving portion 61 that is supported by the leg portion 64. A first contact portion (first plate portion 62) having a first contact surface 621 that can contact the edge W3 of the surface W1, and a second contact surface 631 connected to the first contact surface 621. And a second contact portion (second plate portion 63) having a second contact surface 631 capable of contacting the edge W4 of the back surface W2 of the substrate W. For this reason, when the substrate storage container 1 is transported, the leg portion 64 can be elastically deformed to absorb an impact applied from the outside of the substrate storage container 1, and thereby a plurality of substrates stored in the substrate storage container 1. It is possible to suppress the impact from being transmitted to W as much as possible.

  In addition, the back side substrate support part (wall part substrate support part 60) is provided corresponding to each substrate W, and the leg part 64 of one back side substrate support part (wall part substrate support part 60) is Since each of the leg portions 64 can be elastically deformed independently of the legs 64 of the other back side substrate support portions (wall portion substrate support portions 60), the outside of the substrate storage container 1 is separately provided. It can absorb the impact applied from. For this reason, it can suppress more effectively that an impact is transmitted to the some board | substrate W accommodated in the substrate storage container 1. FIG.

  Moreover, the board | substrate receiving part 61 is elastically deformable, the leg part 64 has the 1st leg part 65 and the 2nd leg part 66, and the one end part of the 1st contact part (1st board part 62). Is connected to one end of the second contact portion (second plate portion 63), the other end of the first contact portion (first plate portion 62) is connected to the first leg portion 65, and the second The other end of the contact portion (second plate portion 63) is connected to the second leg portion 66. For this reason, the substrate receiving portion 61 and the leg portion 64 contact the first contact surface 621 of the substrate receiving portion 61 with the edge W3 of the surface W1 of the substrate W supported by the substrate supporting plate-shaped portion 5 and The edge W4 of the back surface W2 of the substrate W supported by the side substrate support portion (substrate support plate-like portion 5) is pressed against the first contact surface 621 and the second contact surface 631 of the substrate receiving portion 61. When the second contact surface 631 is pressed by the contact, the first contact surface 621 and the second contact surface 631 can be deformed so as to sandwich the edge of the substrate W. Thus, when the substrate W is supported by the lid side substrate support portion (front retainer substrate receiving portion 73) and the back side substrate support portion (wall portion substrate support portion 60), the edge of the substrate W is laterally moved. It can be set as the state spaced apart from the board | substrate support part (board | substrate support plate-shaped part 5).

  Further, the surface W1 of the substrate W supported by the side substrate support portion (substrate support plate-like portion 5) is a surface from the back surface W2 of the substrate W supported by the side substrate support portion (substrate support plate-like portion 5). Since the container body opening 21 is closed by the lid 3, the lid side substrate support is provided because it is located in front of the connection position of the first abutment surface 621 and the second abutment surface 631 in the direction toward W 1. When the substrate W is supported by the portion (front retainer substrate receiving portion 73) and the back side substrate support portion (wall portion substrate support portion 60), the edge W4 of the back surface W2 of the substrate W becomes the second contact surface 631. The edge W4 of the back surface W2 of the substrate W can slide up the second abutting surface 631 until the abutting and the edge W3 of the front surface W1 of the substrate W abut on the first abutting surface 621.

  One end 621A of the first contact surface 621 is connected to one end 631A of the second contact surface 631, and the other end 631B of the second contact surface 631 is a lateral substrate support (substrate support plate). In the direction from the back surface W2 of the substrate W supported by the shaped portion 5) to the front surface W1, it is positioned in front of the back surface W2 of the substrate W supported by the side substrate support portion (substrate support plate-like portion 5). Therefore, when the substrate W is supported by the lid-side substrate support portion (front retainer substrate receiving portion 73) and the back-side substrate support portion (wall portion substrate support portion 60) by closing the opening with the lid 3, the substrate Until the edge W4 of the back surface W2 of W is in contact with the second contact surface 631, and the edge W3 of the surface W1 of the substrate W is in contact with the first contact surface 621, the edge W4 of the back surface W2 of the substrate W is The second contact surface 631 can be slid up.
