The upper surface of the outer peripheral workbench 310 and the upper surface of the inner peripheral workbench 320 are connected by the inclined member 328. That is, the inclined member 328 is arranged in a manner that eliminates the step difference between the upper surface of the outer peripheral workbench 310 and the upper surface of the inner peripheral workbench 320.

[0078] The upper surface of the outer peripheral guide rail 315 is located at the same height as the upper surface of the inner peripheral guide rail 325. That is, the height of the outer peripheral guide rail 315 is shorter than the height of the inner peripheral guide rail 325. For example, the height of the outer peripheral guide rail 315 is formed to be 1 / 2 times the height of the inner peripheral guide rail 325.

[0079] As Figure 4 shown in (C), a pair of partition walls 312 are arranged at both ends of the outer peripheral workbench 310. The lateral width W between the pair of partition walls 312 gradually narrows in the depth direction (the direction from the outer peripheral workbench 310 toward the inner peripheral workbench 320). The lateral width W is the narrowest at the position where the pair of partition walls 312 are adjacent to the inner peripheral workbench 320. The narrowest lateral width W is larger than the maximum lateral width of the reagent container 100. Therefore, the reagent container 100 is transported to the inner peripheral workbench 320 through between the pair of partition walls 312.

[0080] Figure 5 These are three - view drawings showing a structural example of the reagent container 100 of the first embodiment. Figure 5 (A) of this is a left - side view of the reagent container 100. Figure 5 (B) of this is a front view of the reagent container 100. Figure 5 (C) of this is a bottom view of the reagent container 100.

[0081] The reagent container 100 has a shape (conical shape) in which the lateral width gradually narrows from the left side to the right side. That is, the horizontal cross - section of the reagent container 100 has a wedge (trapezoid) shape. The reagent container 100 includes a reagent bottle 110 and an adapter 120. The reagent bottle 110 has an opening member 111 and a main body 112. The adapter 120 has a frame body 121, engaging claws 122, and a cut surface 123. A rectangular fitting groove 130 is formed on the lower surface of the adapter 120. In addition, the horizontal cross - section of the reagent container 100 may also have a rectangular shape.

[0082] The reagent bottle 110 is a bottle for containing a reagent. The opening member 111 is a hollow member formed with an opening through which the first reagent dispensing probe 209 (refer to Figure 2 ) is inserted. The main body 112 is a hollow member for containing a reagent. The opening member 111 and the main body 112 may be integrally formed.

[0083] The adapter 120 is a device that can be detachably attached to the reagent bottle 110. The adapter 120 is attached from the lower surface of the reagent bottle 110. The frame body 121 is a member that fits the shape of the reagent bottle 110. The engaging claws 122 are inverted L - shaped members protruding from the left side surface of the frame body 121. The engaging claws 122 engage with the reagent container arm 220. The cut surface 123 is a surface inclined from the left side surface to the lower surface of the frame body 121. The shape of the cut surface 123 corresponds to the shape of the inclined surface of the inclined member 328.

[0084] The fitting groove 130 is a groove having a shape corresponding to the outer peripheral guide 315 and the inner peripheral guide 325. The reagent container 100 is fitted with the outer peripheral guide 315 and the inner peripheral guide 325 through the fitting groove 130 formed on the lower surface of the adapter 120.

[0085] In addition, when the adapter 120 is not attached to the reagent bottle 110, a fitting groove 130 may be formed on the lower surface of the reagent bottle 110. In this case, the reagent container 100 is regarded as the same as the reagent bottle 110. That is, the reagent container 100 (reagent bottle 110) is fitted with the outer peripheral guide 315 and the inner peripheral guide 325 through the fitting groove 130 formed on the lower surface.

[0086] Figure 6 This is a diagram showing an example of transporting the reagent container 100 of the first embodiment to the inner - peripheral workbench 320.Figure 6 (A) is the front view showing the state in which the reagent container 100 is transported to the outer peripheral workbench 310. Figure 6 (B) is the front view showing the state in which the reagent container 100 is transported to the inner peripheral workbench 320.

[0087] As Figure 6 As shown in (A) of, while the reagent container arm 220 is in contact with the left side surface of the reagent container 100, the reagent container 100 is transported in the direction D1. At this time, the fitting groove 130 of the reagent container 100 is fitted to the outer peripheral guide rail 315 with a certain margin. Through the fitting, the reagent container arm 220 can accurately and smoothly transport the reagent container 100 along the extending direction of the outer peripheral guide rail 315.

[0088] As Figure 6 As shown in (B) of, the reagent container arm 220 transports the reagent container 100 transported to the outer peripheral workbench 310 from the direction D1 to the inner peripheral workbench 320. Due to the step difference between the outer peripheral workbench 310 and the inner peripheral workbench 320, the reagent container 100 slides down along the inclined surface of the inclined member 328 via the cut surface 123. At the same time, the fitting groove 130 of the reagent container 100 is fitted to the inner peripheral guide rail 325 with almost no margin. Through the fitting, the reagent container arm 220 can accurately and smoothly transport the reagent container 100 along the extending direction of the inner peripheral guide rail 325.

[0089] By the rotation of the inner peripheral workbench 320, a centrifugal force opposite to the direction D1 is applied to the reagent container 100 transported to the inner peripheral workbench 320. At this time, the step difference between the outer peripheral workbench 310 and the inner peripheral workbench 320 prevents the reagent container 100 from being pushed back to the outer peripheral workbench 310 due to the centrifugal force. That is, this step difference can fix the reagent container 100 to the inner peripheral workbench 320.

[0090] Figure 7 It is a view showing an example of transporting the reagent container 100 from the inner peripheral workbench 320 in the first embodiment. Figure 7 (A) is the front view showing the state in which the reagent container 100 is transported to the inner peripheral workbench 320. Figure 7 (B) is the front view showing the state in which the reagent container 100 is transported to the outer peripheral workbench 310.

[0091] As Figure 7As shown in (A), while engaging with the engaging claw 122 of the reagent container 100, the reagent container arm 220 transports the reagent container 100 in the direction D2 opposite to the direction D1. Due to the step difference between the outer peripheral workbench 310 and the inner peripheral workbench 320, the reagent container 100 slides on the inclined surface of the inclined member 328 via the cut surface 123. At the same time, the fitting groove 130 of the reagent container 100 engages with the outer peripheral guide rail 315 with a certain margin. Through this engagement, the reagent container arm 220 can accurately and smoothly transport the reagent container 100 along the extending direction of the outer peripheral guide rail 315.

[0092] As Figure 7 As shown in (B), while engaging with the engaging claw 122 of the reagent container 100, the reagent container arm 220 transports the reagent container 100 in the direction D2. The reagent container arm 220 transports the reagent container 100 to the outside of the first reagent reservoir 204 through the opening 204H.

[0093] According to the first embodiment described above, the automatic analysis device 1 transports the reagent container 100 not from the "above" but from the "side" of the first reagent reservoir 204. Specifically, the automatic analysis device 1 transports the reagent container 100 held by the reagent container arm 220 into the first reagent reservoir 204 through the opening 204H formed in the housing 204A of the first reagent reservoir 204. On the other hand, the automatic analysis device 1 transports the reagent container 100 held by the reagent container arm 220 to the outside of the first reagent reservoir 204 through the opening 204H.

[0094] That is, the automatic analysis device 1 pushes or pulls out the reagent container 100 held by the reagent container arm 220 in the horizontal direction through the opening 204H. At this time, since the reagent container arm 220 does not need to move in the vertical direction, the motion control or structure of the reagent container arm 220 is simplified. Therefore, the automatic analysis device 1 can reduce the cost of the entire device including the reagent container arm 220.

[0095] (Modification of the First Embodiment)

[0096] Figure 8 It is a diagram showing a configuration example of reagent containers (100A, 100B, 100C, 100D) and guide rails (335A, 335B, 335C, 335D) of a modification of the first embodiment. Figure 8 (A) is a left side view of the reagent container 100A and the guide rail 335A. Figure 8 (B) is a left side view of the reagent container 100B and the guide rail 335B. Figure 8 (C) is a left side view of the reagent container 100C and the guide rail 335C. Figure 8 (D) is a left side view of the reagent container 100D and the guide rail 335D.

[0097] As shown in Figure 8 (A) of FIG. 1, a T-shaped fitting groove 130A is formed in the lower part of the reagent container 100A. The guide rail 335A is T-shaped corresponding to the shape of the fitting groove 130A. The guide rail 335A is an example of the outer peripheral guide rail 315 or the inner peripheral guide rail 325.

[0098] The reagent container arm 220 transports the reagent container 100A while fitting the fitting groove 130A of the reagent container 100A to the guide rail 335A. At this time, the movement of the reagent container 100A is restricted by the shape of the guide rail 335A so as not to swing not only in the horizontal direction but also in the vertical direction. Therefore, the reagent container arm 220 can transport the reagent container 100A more stably along the extending direction of the guide rail 335A. From another aspect, the T-shaped fitting groove 130A and the guide rail 335A can prevent the reagent accommodated in the reagent container 100A from foaming due to the swing of the reagent container 100A.

[0099] As shown in Figure 8 (B) of FIG. 1, a pair of fitting grooves 130B each having a rectangular shape are formed in the lower part of the reagent container 100B. One fitting groove 130B has a shape that is reversed left and right with respect to the other fitting groove 130B. A pair of guide rails 335B are each in an inverted L shape so as to fit with the pair of fitting grooves 130B. The guide rail 335B is an example of the outer peripheral guide rail 315 or the inner peripheral guide rail 325.

[0100] The reagent container arm 220 transports the reagent container 100B while fitting the pair of fitting grooves 130B of the reagent container 100B to the pair of guide rails 335B. At this time, the movement of the reagent container 100B is restricted by the shape of the pair of guide rails 335B so as not to swing not only in the horizontal direction but also in the vertical direction. Therefore, the reagent container arm 220 can transport the reagent container 100B more stably along the extending direction of the pair of guide rails 335B. From another aspect, the pair of rectangular fitting grooves 130B and the pair of inverted L-shaped guide rails 335B can prevent the reagent accommodated in the reagent container 100B from foaming due to the swing of the reagent container 100B.

[0101] As shown in Figure 8 (C) of FIG. 1, the reagent container 100C is different from the reagent container 100 and does not form a fitting groove 130. A pair of guide rails 335C are each in an inverted L shape so as to sandwich the reagent container 100C from the horizontal direction. In particular, a part of the pair of guide rails 335C is arranged so as to cover the upper surface of the main body 112 (frame 121). The guide rail 335C is an example of the outer peripheral guide rail 315 or the inner peripheral guide rail 325.

[0102] The reagent container arm 220 transports the reagent container 100C between a pair of guide rails 335C. At this time, the reagent container 100C is restricted in movement in a manner that does not swing not only in the horizontal direction but also in the vertical direction by the shape of the pair of guide rails 335C. Therefore, the reagent container arm 220 can transport the reagent container 100C more stably along the direction in which the pair of guide rails 335C extends. From another perspective, the pair of guide rails 335C can prevent foaming of the reagent contained in the reagent container 100C due to the swinging of the reagent container 100C.

[0103] As Figure 8 shown in (D) thereof, the reagent container 100D is different from the reagent container 100 and does not form the fitting groove 130. A pair of guide rails 335D are arranged so as to sandwich the lower part of the reagent container 100D in the horizontal direction. The guide rail 335D is an example of the outer peripheral guide rail 315 or the inner peripheral guide rail 325.

[0104] The reagent container arm 220 transports the reagent container 100D between a pair of guide rails 335D. At this time, the movement of the reagent container 100D is restricted by the shape of the pair of guide rails 335D so as not to swing in the horizontal direction. Therefore, the reagent container arm 220 can stably transport the reagent container 100D along the direction in which the pair of guide rails 335D extends. From other perspectives, the pair of guide rails 335D can prevent foaming of the reagent contained in the reagent container 100D due to the swinging of the reagent container 100D.

[0105] Figure 8 The pair of guide rails 335D shown in (D) thereof restricts the swinging of the reagent container 100D in the horizontal direction. On the other hand, Figure 5 the fitting of the fitting groove 130 shown in (A) thereof with the outer peripheral guide rail 315 or the inner peripheral guide rail 325 restricts the swinging of the reagent container 100 in the horizontal direction. That is, the pair of guide rails 335D has the same effect as the fitting of the fitting groove 130 with the outer peripheral guide rail 315 or the inner peripheral guide rail 325.

[0106] (Second Embodiment)

[0107] Figure 9 is a diagram showing a configuration example of each workbench and the reagent container 100G of the second embodiment. Figure 9 (A) thereof is a front view of the outer peripheral workbench 310 and the inner peripheral workbench 320. Figure 9 (B) thereof is a front view of the reagent container 100G.

[0108] As Figure 9As shown in (A) of FIG. , the outer peripheral workbench 310 has a protrusion member 316 at one end adjacent to the inner peripheral workbench 320. The inner peripheral workbench 320 has a protrusion member 326 at one end adjacent to the inner wall 320A. The protrusion members 316 and 326 have the same shape (e.g., triangular, semi-circular). The protrusion members 316 and 326 are formed to a specified size so as to lift and fit the reagent container 100G.

[0109] As shown in Figure 9 (B) of FIG. , a fitting groove 140 is formed on the lower surface of the right side surface of the reagent container 100G. The fitting groove 140 has a shape corresponding to the protrusion members 316 and 326.

[0110] Figure 10 FIG. is a diagram showing an example of transporting the reagent container 100G of the second embodiment to each workbench. Figure 10 (A) of FIG. is a front view showing a state where the reagent container 100G is transported to the outer peripheral workbench 310. Figure 10 (B) of FIG. is a front view showing a state where the reagent container 100G is transported to the inner peripheral workbench 320.

[0111] As shown in Figure 10 (A) of FIG. , the reagent container arm 220 transports the reagent container 100G along the direction D1 while contacting the left side surface of the reagent container 100G. At this time, the fitting groove 140 of the reagent container 100G is lifted and fitted to the protrusion member 316. By the fitting, the reagent container 100G is fixed to the outer peripheral workbench 310.

[0112] By the rotation of the outer peripheral workbench 310, a centrifugal force opposite to the direction D1 is applied to the reagent container 100G transported to the outer peripheral workbench 310. At this time, the fitting between the fitting groove 140 and the protrusion member 316 prevents the reagent container 100G from passing through the opening 204H and being pushed back to the outside due to the centrifugal force. That is, this fitting can fix the reagent container 100G to the outer peripheral workbench 310.

[0113] As shown in Figure 10 (B) of FIG. , the reagent container arm 220 transports the reagent container 100G fixed to the outer peripheral workbench 310 along the direction D1 to the inner peripheral workbench 320. At this time, the fitting between the fitting groove 140 of the reagent container 100G and the protrusion member 316 is released, and it is lifted and fitted to the protrusion member 326. By the fitting, the reagent container 100G is fixed to the inner peripheral workbench 320.

[0114] By rotating the inner peripheral worktable 320, a centrifugal force opposite to the direction D1 is applied to the reagent container 100G transported to the inner peripheral worktable 320. At this time, the fitting between the fitting groove 140 and the protruding member 326 prevents the reagent container 100G from being pushed back to the outer peripheral worktable 310 due to the centrifugal force. That is, this fitting can fix the reagent container 100G to the inner peripheral worktable 320.

[0115] The reagent container 100G of the second embodiment is transported to the outside of the first reagent reservoir 204 by the same method as the first embodiment. That is, the reagent container arm 220 transports the reagent container 100G along the direction D2 opposite to the direction D1 while engaging with the engaging claws 122 of the reagent container 100G (see Figure 7 ).

[0116] According to the second embodiment described above, the automatic analyzer 1 has the same effect as the first embodiment. Furthermore, the automatic analyzer 1 can fix the reagent container 100G to the outer peripheral worktable 310 or the inner peripheral worktable 320 by engaging the fitting groove 140 of the reagent container 100G with the protruding member 316 or 326.

[0117] (Third Embodiment)

[0118] Figure 11 FIG. is a diagram showing a configuration example of each worktable and each reagent container of the third embodiment. Figure 11 FIG. (A) is a front view of the outer peripheral worktable 310 and the inner peripheral worktable 320. Figure 11 FIG. (B) is a front view of the reagent container 100P (first reagent container). Figure 11 FIG. (C) is a front view of the reagent container 100Q (second reagent container).

[0119] As Figure 11 shown in FIG. (A), the outer peripheral worktable 310 has a magnet 400A (first magnet). The magnet 400A is disposed at the central portion of the outer peripheral worktable 310. The inner wall 320A has a magnet 400B (second magnet). The magnet 400B is disposed at the central portion of the inner wall 320A.

[0120] As Figure 11 shown in FIG. (B), a magnetic body 500P (first magnetic body) is disposed at the central portion of the lower surface of the reagent container 100P. The magnetic body 500P may be a member formed of a ferromagnetic material such as iron, cobalt, or nickel. Typically, the magnetic body 500P is an iron plate.

[0121] As Figure 11As shown in (C), a magnet 500Q (second magnet) is disposed at the center of the right side surface of the reagent container 100Q. The magnet 500Q may be a member formed of a ferromagnetic material such as iron, cobalt, or nickel. Typically, the magnet 500Q is an iron plate.

[0122] Figure 12 FIG. is a diagram showing an example of transporting each reagent container of the third embodiment to each workbench. Figure 12 (A) of FIG. is a front view showing a state where the reagent container 100P is transported to the outer peripheral workbench 310. Figure 12 (B) of FIG. is a front view showing a state where the reagent container 100Q is transported to the inner peripheral workbench 320.

[0123] As Figure 12 As shown in (A) of FIG., the reagent container arm 220 transports the reagent container 100P along the direction D1 while contacting the left side surface of the reagent container 100P. At this time, a magnetic adsorption force is generated between the magnet 400A of the outer peripheral workbench 310 and the magnet 500P of the reagent container 100P. By the adsorption force, the reagent container 100P is fixed to the outer peripheral workbench 310.

[0124] By the rotation of the outer peripheral workbench 310, a centrifugal force opposite to the direction D1 is applied to the reagent container 100P transported to the outer peripheral workbench 310. At this time, the adsorption between the magnet 400A and the magnet 500P prevents the reagent container 100P from being pushed back to the outside through the opening 204H due to the centrifugal force. That is, this adsorption can fix the reagent container 100P to the outer peripheral workbench 310.

[0125] As Figure 12 As shown in (B) of FIG., the reagent container arm 220 transports the reagent container 100Q along the direction D1 while contacting the left side surface of the reagent container 100Q. At this time, a magnetic adsorption force is generated between the magnet 400B on the inner wall 320A and the magnet 500Q of the reagent container 100Q. By the adsorption force, the reagent container 100Q is fixed to the inner peripheral workbench 320 adjacent to the inner wall 320A.

[0126] By the rotation of the inner peripheral workbench 320, a centrifugal force opposite to the direction D1 is applied to the reagent container 100Q transported to the inner peripheral workbench 320. At this time, the adsorption between the magnet 400B and the magnet 500Q prevents the reagent container 100Q from being pushed back to the outer peripheral workbench 310 due to the centrifugal force. That is, this adsorption can fix the reagent container 100Q to the inner peripheral workbench 320.

[0127] The reagent containers 100P and 100Q of the third embodiment are transported to the outside of the first reagent reservoir 204 by the same method as in the first embodiment. That is, the reagent container arm 220 transports the reagent container 100P along the direction D2 opposite to the direction D1 while engaging with the engaging claw 122 of the reagent container 100P. The reagent container arm 220 transports the reagent container 100Q along the direction D2 while engaging with the engaging claw 122 of the reagent container 100Q (see Figure 7 ).

[0128] Here, assume a case where the reagent container arm 220 transports the reagent container 100Q fixed to the inner peripheral workbench 320 along the direction D2. In this case, the reagent container arm 220 peels off the magnetic body 500Q adsorbed to the magnet 400B along the direction D2. Then, the reagent container arm 220 transports the reagent container 100Q to the outside of the first reagent reservoir 204 through the outer peripheral workbench 310.

[0129] When the reagent container 100Q passes over the outer peripheral workbench 310, a certain distance is maintained between the magnet 400A of the outer peripheral workbench 310 and the magnetic body 500Q of the reagent container 100Q. This distance is larger than the distance between the magnet 400A of the outer peripheral workbench 310 and the magnetic body 500P of the reagent container 100P. Therefore, compared with the reagent container 100P, the reagent container 100Q is hardly adsorbed by the magnet 400A and is smoothly transported.

[0130] In addition, the inner peripheral workbench 320 may also have a magnet 400B at the center in the same manner as the outer peripheral workbench 310. In this case, the reagent container 100Q may also have a magnetic body 500Q at the center of the lower surface in the same manner as the reagent container 100P. That is, the reagent container 100Q may have the same configuration as the reagent container 100P.

[0131] In the above case, the reagent container arm 220 transports the reagent container 100Q to the inner peripheral workbench 320 while contacting the left side surface of the reagent container 100Q. At this time, a magnetic adsorption force is generated between the magnet 400B of the inner peripheral workbench 320 and the magnetic body 500Q of the reagent container 100Q. By the adsorption force, the reagent container 100Q is fixed to the inner peripheral workbench 320.

[0132] According to the third embodiment described above, the automatic analysis device 1 achieves the same effect as in the first embodiment. Furthermore, the automatic analysis device 1 can fix the reagent container 100P to the outer peripheral worktable 310 by the adsorption force between the magnet 400A of the outer peripheral worktable 310 and the magnetic body 500P of the reagent container 100P. The automatic analysis device 1 can fix the reagent container 100Q to the inner peripheral worktable 320 by the adsorption force between the magnet 400B of the inner wall 320A and the magnetic body 500Q of the reagent container 100Q.

[0133] (Each embodiment)

[0134] Figure 13 It is a plan view showing an example of rotation control of each worktable in each embodiment. Figure 13 In (A), it is a plan view before the rotation of the outer peripheral worktable 310 and the inner peripheral worktable 320. Figure 13 In (B), it is a plan view after the rotation of the outer peripheral worktable 310 and the inner peripheral worktable 320.

[0135] As Figure 13 As shown in (A), in the outer peripheral worktable 310 and the inner peripheral worktable 320, a plurality of reagent containers 100 are arranged at equal intervals on the circumference around the rotation center P. In other words, the plurality of reagent containers 100 are arranged symmetrically with respect to the rotation center P point. With this configuration, a load is evenly applied to each position of the outer peripheral worktable 310 or the inner peripheral worktable 320. Therefore, this configuration can reduce the vibration accompanying the rotation of the outer peripheral worktable 310 or the inner peripheral worktable 320.

[0136] Here, two reagent containers 100 are arranged in the direction D1 (refer to Figure 3 ) from the opening 204H toward the rotation center P. Specifically, in the direction D1, a reagent container 100 is arranged in the space 311 of the outer peripheral worktable 310, and another reagent container 100 is arranged in the space 321 of the inner peripheral worktable 320. In this case, in order to transport the reagent container 100 to the idle space 321 of the inner peripheral worktable 320, the automatic analysis device 1 needs to rotate the outer peripheral worktable 310 and the inner peripheral worktable 320 respectively.

[0137] For example, the automatic analysis device 1 determines the idle space 311 in the outer peripheral worktable 310 at the position closest to the opening 204H through the determination function 91. When the outer peripheral worktable 310 rotates clockwise, the determination function 91 determines the space 311E as this idle space 311.

[0138] Similarly, the automatic analysis device 1 determines the free space 321 in the inner peripheral workbench grid 320 at the position closest to the opening 204H through the determination function 91. When the inner peripheral workbench 320 rotates clockwise, the determination function 91 determines the space 321E as the free space 321.

[0139] Next, the automatic analysis device 1 rotates the outer peripheral workbench 310 through the system control function 92 and the drive mechanism 4 so that the space 311E determined by the determination function 91 approaches the position of the opening 204H (adjacent to the position of the opening 204H).

[0140] Similarly, the automatic analysis device 1 rotates the inner peripheral workbench 320 through the system control function 92 and the drive mechanism 4 so that the space 321E determined by the determination function 91 approaches the position of the opening 204H.

[0141] As Figure 13 shown in (B) of, the automatic analysis device 1 rotates the outer peripheral workbench 310 in the direction DR1 and rotates the inner peripheral workbench 320 in the direction DR2. Through the rotation of each workbench, the spaces 311E and 321E are located in the direction D1. The automatic analysis device 1 transports the reagent container 100 to the space 321E through the opening 204H and the space 311E by using the reagent container arm 220.

[0142] Through the above actions, the automatic analysis device 1 suppresses the rotation distance (rotation angle) of the outer peripheral workbench 310 and the inner peripheral workbench 320 to the minimum. Therefore, the automatic analysis device 1 can quickly transport the reagent container 100 held by the reagent container arm 220 to the free space 321 of the inner peripheral workbench 320. Furthermore, the automatic analysis device 1 can prevent the reagents contained in the multiple reagent containers 100 from foaming for the multiple reagent containers 100 provided on the outer peripheral workbench 310 or the inner peripheral workbench 320.

[0143] (Other modification examples)

[0144] First, the automatic analysis device 1 may also rotate the outer peripheral workbench 310 or the inner peripheral workbench 320 so that the specified free space 311 or 321 selected by the operator via the input IF6 approaches the position of the opening 204H. In this case, the automatic analysis device 1 can transport the reagent container 100 to the free space 311 or 321 desired by the operator.

[0145] Second, the automatic analysis device 1 can also determine the distance from the position of the opening 204H to the space 311E or 321E through the determination function 91. This distance can also be the "linear distance" from the position of the opening 204H to the space 311E or 321E. Alternatively, this distance can also be the "rotation distance" (rotation angle) of the outer peripheral workbench 310 or the inner peripheral workbench 320 required to bring the space 311E or 321E closer to the position of the opening 204H.

[0146] In this case, the automatic analysis device 1 can also change the rotation speed of the outer peripheral workbench 310 or the inner peripheral workbench 320 according to the above distance through the system control function 92 and the drive mechanism 4. For example, the shorter the above distance, the higher the rotation speed of the outer peripheral workbench 310 or the inner peripheral workbench 320 that the automatic analysis device 1 makes. Thereby, the automatic analysis device 1 can quickly bring the space 311E or 321E relatively close to the position of the opening 204H closer to the position of the opening 204H. On the other hand, the automatic analysis device 1 can bring the space 311E or 321E relatively far from the position of the opening 204H closer to the position of the opening 204H so that the reagents contained in each reagent container 100 do not foam.

[0147] Third, the automatic analysis device 1 can also determine the free space 311 or 321 (setting space) where the reagent container 100 can be set through the determination function 91 so that a plurality of reagent containers 100 are arranged at equal intervals in a circle on the outer peripheral workbench 310 or the inner peripheral workbench 320. For example, the determination function 91 determines whether a pair of reagent containers 100 is arranged for each pair of spaces 311 or 321 symmetrically arranged with respect to the rotation center P point. For the determined pair of spaces 311 or 321, when a reagent container 100 is arranged only in one of the spaces 311, the other space 311 is determined as the above free space 311 or 321.

[0148] In this case, the automatic analysis device 1 transports the reagent container 100 to the above free space 311 or 321 through the reagent container arm 220. Thereby, the automatic analysis device 1 can arrange a plurality of reagent containers 100 at equal intervals on the outer peripheral workbench 310 or the inner peripheral workbench 320. That is, the automatic analysis device 1 achieves the effects described above (refer to Figure 13 of (A)).

[0149] Fourth, the automatic analysis device 1 can also transport the reagent container 100 to the inner peripheral workbench 320 in a lifted state through the reagent container arm 220 without placing the reagent container 100 on the outer peripheral workbench 310. That is, the reagent container arm 220 can also place the lifted reagent container 100 on the inner peripheral workbench 320 without contacting the outer peripheral workbench 310.

[0150] Fifth, the outer peripheral workbench 310 may also have at least one free space for not setting the reagent container 100. This free space may also be formed in a linear passage shape. This free space may also be formed at equal intervals on the circumference of the outer peripheral workbench 310. Specifically, with respect to the angle θ (°) around the rotation center P, this free space may be formed in θ / 360 (parts) for each angle θ. For example, when the angle θ = 180, 120, 90, this free space is formed at equal intervals in two places, three places, and four places, respectively. The automatic analyzer 1 may also use the reagent container arm 220 to transport the reagent container 100 to the inner peripheral workbench 320 through this free space formed in the outer peripheral workbench 310.

[0151] Suppose that the outer peripheral workbench 310 only has a plurality of spaces for setting the reagent container 100, and the reagent container 100 is set in all of these plurality of spaces. In this case, there is no free space in the outer peripheral workbench 310, so the reagent container arm 220 cannot transport the reagent container 100 to the inner peripheral workbench 320 through this free space.

[0152] On the other hand, when the outer peripheral workbench 310 has at least one free space for not setting the reagent container 100, the reagent container arm 220 can transport the reagent container 100 to the inner peripheral workbench 320 through this free space. That is, the outer peripheral workbench 310 has a dedicated free space for transporting the reagent container 100 to the inner peripheral workbench 320, whereby the reagent container 100 can move freely between the outer peripheral workbench 310 and the inner peripheral workbench 320.

[0153] According to at least one of the embodiments described above, the structure of the automatic analyzer can be simplified.
