On the other hand, the screw B and the nut N are used for sealing, and the screw B is fixed to the side plate 7 through the holes 36A and 46A.

  Similarly, as shown in FIG. 4, the inner flange member 35 described above seals the ring portion 36 against the inner surface 6M of the side plate 6, and the outer flange member 45 connects the ring portion 46 to the side plate 6. The outer surface 6N is hermetically sealed, and the screws B and nuts N are used to pass the screws B through the holes 36A and 46A and are fixed to the side plate 6.

  Thus, the connecting device 30 is fixed corresponding to the opening 20 of the side plate 7, and the connecting device 31 is fixed corresponding to the opening 21 of the side plate 6.

  Next, the sample mounting table (mounting table) 60 shown in FIG. 4 will be described with reference to FIG. 4 and FIGS. 9 to 12.

  FIG. 9 is a perspective view showing the sample mounting table 60, and FIG. 10 is a front view showing the sample mounting table 60. 11 is a side view showing the sample mounting table 60 from the R1 direction in FIG. 10, and FIG. 12 is a side view showing the sample mounting table 60 from the R2 direction in FIG.

  In the usage example of the sample mounting table 60 in FIG. 4, the sample mounting table 60 is attached in a state in which the opening 20 is passed through one coupling device 30 side. The sample mounting table 60 is a support table for temporarily placing a container M containing a weighed high physiologically active powder as a sample in the work space 4 of the main body 1, for example.

  As shown in FIG. 9, the sample mounting table 60 includes an upper surface portion 61, a first attachment portion 62, and a second attachment portion 63. The upper surface portion 61 is a rectangular plate member and is a portion on which the container M is placed. The first mounting portion 62 is formed by bending from the end portion of the upper surface portion 61 and has an arc-shaped end portion 64.

  The first mounting portion 62 is provided with a screw hole 62H. As shown in FIG. 4, the first attachment portion 62 can be fixed to the attachment protrusion portion 39 of the inner flange member 35 by passing the screw 62N through the screw hole 62H.

Can be supported. Moreover, the upper surface portion 61 of the sample mounting table 60 is held in a horizontal state, and the upper surface portion 61 supports the container M temporarily and stably so that the container M does not fall down.

  In this way, since the container M can be temporarily supported, the operator passes the container M from the work space 4 of the one main body 1 through the flexible connecting member 50 to the other main body 1A as the next step. Can be safely and reliably delivered to the work space 4. Thus, the operator can smoothly deliver the container M through the flexible connecting member 50. In addition, the shape of the illustrated sample mounting table 60 is an example, and an arbitrary shape can be adopted.

  As shown in FIG. 4, the flexible connecting member 50 can be exchanged between the connecting device 30 of the opening 20 and the connecting device 31 of the opening 21 using two attachment bands 29 and 29. It is attached.

In addition, the opening end 52 is sealed over the entire circumference of the cylindrical portion 47 in the mounting recesses 45H and 45G using the elastic force of another expandable ring-shaped mounting band 29.

  Thereby, the flexible connecting member 50 is attached between the outer flange member 45 of the coupling device 30 and the outer flange member 45 of the coupling device 31 while maintaining a sealed state. For this reason, one opening 20 and the other opening 21 are connected in a sealed state from the outside using a flexible connecting member 50. For this reason, the working space 4 of one main body 1 and the working space 4 of the other main body 1A communicate with each other through the openings 20 and 21, but do not communicate with the outside of the main bodies 1 and 1A. Is maintained.

  Thus, the flexible connecting member 50 can connect the outer flange members 45, 45 in a sealed state. Since the flexible connecting member 50 itself can be freely deformed, the operator can easily seal the flexible connecting member 50 against the outer flange members 45 and 45 using the mounting band 29. It can be installed smoothly while securing the condition.

  Next, with reference to FIGS. 13 to 20, an example of an operation for removing the flexible connection member 50 from the outer flange members 45 and 45 and an operation for attaching the connection member 50 again will be described.

In the work space 4 of the main body 1, for example, a highly physiologically active powder as a part to be treated is weighed and subdivided into a container M, for example, while being sealed in the work space 4. In the work space 4 of the other main body 1A, the next work process is performed while the highly physiologically active powder in the container M is sealed in the work space 4.

  FIG. 13 shows, for example, a case in which a highly physiologically active powder container M is sent from the work space 4 of one main body 1 into the work space 4 of the other main body 1A through the flexible connecting member 50 and then the one main body 1A. 1 shows a state in which one opening 20 and the opening 21 of the other main body 1A are closed by closing bags B1 and B2.

  In the state shown in FIG. 13, the open end 51 on one end side of the flexible connection member 50 is already in the recesses 45H and 45G for mounting the flange member 45 on the outer side of the coupling device 30, and the open end The part 51 is attached by a ring-shaped attachment band 29. Thereby, the open end 51 on one end side is hermetically attached to the cylindrical portion 47 of the outer flange member 45 by the elastic force of the attachment band 29.

  Similarly, in the state shown in FIG. 13, the open end 52 on the other end side of the flexible connection member 50 is in the recesses 45H and 45G for mounting the flange member 45 on the outside of the coupling device 31. The open end 52 is attached by a ring-shaped attachment band 29. Thereby, the opening end 52 on the other end side is hermetically attached to the cylindrical portion 47 of the outer flange member 45 by the elastic force of the attachment band 29.

  In this way, with the flexible connecting member 50 sealingly connecting the openings 20 and 21, the closing bags B1 and B2 are prepared, and the flexible connecting member 50 is separated and detached. Do.
