Description

[Technical Field]

[0001] The embodiments disclosed in this specification and the drawings relate to an automated analyzer and a control method. [Background technology]

[0002] An automated analyzer is a device that automatically analyzes a sample (e.g., blood, urine) to measure the concentration of various components in the sample. An automated analyzer mixes a reagent with the sample, irradiates the mixture with light, and performs various measurements based on the amount of transmitted or scattered light obtained.

[0003] A reagent storage unit of an automated analyzer holds multiple reagent containers containing reagents. Some types of reagent storage units are equipped with an outer table and an inner table that rotate independently of each other. In an automated analyzer equipped with such a reagent storage unit, a technique is known in which a reagent container is lifted by a robot arm and loaded onto the outer table or the inner table from above the reagent storage unit.

[0004] However, with the above technology, it is necessary to provide the reagent storage with entrances corresponding to the outer and inner tables so that the robot arm can access the outer and inner tables. Furthermore, it is necessary to control the robot arm so that it can access these two entrances. Therefore, the above technology complicates the structure of the automated analyzer, leading to problems such as increased costs. [Prior art documents] [Patent documents]

The memory circuit 5 is an example of a memory unit.

[0015] The memory circuitry 5 stores an analysis program executed by the analysis circuitry 3 and a control program executed by the control circuitry 9.

The memory circuitry 5 stores test orders input by the operator via the input IF6, and stores test orders received by the communication IF8 via the hospital network NW.

[0016] The input IF6 is an interface that accepts various input operations. The input IF6 is realized by a mouse, a keyboard, a touchpad, a touch panel, or the like. The input IF6 may be a processing circuit that receives an electrical signal corresponding to a predetermined operation instruction from an external input device provided separately from the automatic analyzer 1 and outputs this electrical signal to the control circuit 9. The input IF6 converts the input operation accepted from the operator into an electrical signal and outputs this electrical signal to the control circuit 9.

When the processor is a CPU, the CPU realizes each function by reading and executing a control program stored in the memory circuit 5. When the processor is an ASIC, each function is directly incorporated as a logic circuit within the ASIC circuit. The processor may be configured as a single circuit or may be configured by combining multiple independent circuits. The control circuit 9 realizes a specific function 91 and a system control function 92. The control circuit 9 is an example of a control unit.

The identification function 91 is an example of an identification unit.

[0024] The system control function 92 is a function that controls the overall operation of the automatic analyzer 1. For example, the system control function 92 controls the operation of the drive mechanism 4 so that a sample is measured according to a predetermined test item. The system control function 92 controls the operation of the analysis circuit 3 so that the test data and standard data generated by the analysis mechanism 2 are analyzed. The system control function 92 may also control the reagent storage and robot arm of the analysis mechanism 2. The system control function 92 is an example of a system control unit.

The sample dispensing arm 206 moves vertically and rotates horizontally under the control of the drive mechanism 4. The sample dispensing arm 206 is disposed between the reaction disk 201 and the sample disk 203.

[0035] The sample dispensing probe 207 is a probe that dispenses a sample into a reaction vessel 2011. The sample dispensing probe 207 moves in the same direction as the sample dispensing arm 206. The sample dispensing probe 207 aspirates a sample from a sample vessel 2031 under the control of the driving mechanism 4, and dispenses the aspirated sample into the reaction vessel 2011.

[0046] 3 is a top view showing an example of the configuration of the first reagent storage 204 according to the first embodiment. The first reagent storage 204 has a housing 204A adjacent to one end of the outer circumferential table 310, and has an opening 204H through which a reagent container 100 can be inserted. The inner circumferential table 320 has an inner wall 320A at one end not adjacent to the outer circumferential table 310. A shaft 330 is disposed inside the inner wall 320A. The center of the shaft 330 corresponds to the center of rotation P.

[0047] The first reagent storage 204 has an outer peripheral table 310 on which a plurality of reagent containers 100 are placed, and an inner peripheral table 320 on which a plurality of reagent containers 100 are placed. The outer peripheral table 310 and the inner peripheral table 320 rotate independently of each other around a rotation center P under the control of a drive mechanism 4. The outer peripheral table 310 is an example of an outer peripheral installation unit. The inner peripheral table 320 is an example of an inner peripheral installation unit.

[0048] The peripheral table 310 has spaces 311 in which a plurality of reagent containers 100 are respectively placed. A pair of partition walls 312 extending in the radial direction of the peripheral table 310 is arranged in each space 311. The reagent containers 100 placed in each space 311 are supported by the pair of partition walls 312. The partition walls 312 can prevent the reagent containers 100 from tipping over due to centrifugal force generated by the rotation of the peripheral table 310. The partition walls 312 are an example of a guide portion.

[0049] The inner circumferential table 320 is located inside the outer circumferential table 310 and has spaces 321 in which a plurality of reagent containers 100 are respectively placed. A pair of partition walls 322 extending in the radial direction of the inner circumferential table 320 is arranged in each space 321. The reagent containers 100 placed in each space 321 are supported by the pair of partition walls 322. The partition walls 322 can prevent the reagent containers 100 from tipping over due to centrifugal force generated by the rotation of the inner circumferential table 320. The partition walls 322 are an example of a guide portion.

[0050] The reagent container arm 220 transports the reagent container 100 it holds in direction D1 from the opening 204H toward the center of rotation P. That is, the reagent container arm 220 transports the reagent container 100 through the opening 204H and the outer circumferential table 310 to the inner circumferential table 320. At this time, the reagent container arm 220 transports the reagent container 100 via partition walls 312 and 322. Spaces 311 and 321 (empty spaces) in which no other reagent containers 100 are installed are located on the transport path of the reagent container 100 along direction D1. The reagent container arm 220 transports the reagent container 100 to the empty space 321 on the inner circumferential table 320 through the empty space 311 on the outer circumferential table 310 (or between multiple reagent containers 100 installed on the outer circumferential table 310).

[0051] Fig. 4 is a three-view diagram showing an example of the configuration of each table according to the first embodiment. Fig. 4 shows spaces 311 and 321 located on the transport path of the reagent container 100 along direction D1 in Fig. 3. Fig. 4(A) is a top view of the outer peripheral table 310 and the inner peripheral table 320. Fig. 4(B) is a front view of the outer peripheral table 310 and the inner peripheral table 320. Fig. 4(C) is a left side view of the outer peripheral table 310.

[0052] As shown in FIG. 4(A), the outer peripheral table 310 has an outer peripheral rail 315 extending in the radial direction of the outer peripheral table 310. The outer peripheral rail 315 has a rectangular cross section and is arranged so as to bisect the space 311. The inner peripheral table 320 has an inner peripheral rail 325 extending in the radial direction of the inner peripheral table 320. The inner peripheral rail 325 has a rectangular cross section and is arranged so as to bisect the space 321. The outer peripheral rail 315 and the inner peripheral rail 325 are positioned on a straight line. The outer peripheral rail 315 and the inner peripheral rail 325 are examples of guide units.

[0053] The outer circumferential rails 315 may be arranged in each space 311 of the outer circumferential table 310. The inner circumferential rails 325 may be arranged in each space 321 of the inner circumferential table 320.

[0054] The inner peripheral table 320 has an inclined member 328 at one end adjacent to the outer peripheral table 310. The inclined member 328 has an inclined surface that slopes from the upper surface of the outer peripheral table 310 to the upper surface of the inner peripheral table 320.

[0055] 4(B), the housing 204A is disposed adjacent to one end of the outer circumferential table 310. An opening 204H is located above the housing 204A. The inner wall 320A is disposed adjacent to one end of the inner circumferential table 320.

[0056] The upper surface of the outer peripheral table 310 is located vertically higher than the upper surface of the inner peripheral table 320. The upper surfaces of the outer peripheral table 310 and the inner peripheral table 320 are connected by an inclined member 328. In other words, the inclined member 328 is positioned so as to eliminate the difference in level between the upper surfaces of the outer peripheral table 310 and the inner peripheral table 320.

[0057] The upper surface of the outer circumferential rail 315 is located at the same height as the upper surface of the inner circumferential rail 325. That is, the height of the outer circumferential rail 315 is shorter than the height of the inner circumferential rail 325. For example, the height of the outer circumferential rail 315 is formed to be half the height of the inner circumferential rail 325.

[0058] As shown in FIG. 4(C), a pair of partition walls 312 are disposed at both ends of the outer peripheral table 310. The width W between the pair of partition walls 312 gradually narrows in the depth direction (the direction from the outer peripheral table 310 toward the inner peripheral table 320). The width W is narrowest at a position where the pair of partition walls 312 are adjacent to the inner peripheral table 320. The width W at its narrowest point is greater than the maximum width of the reagent container 100. Therefore, the reagent container 100 is transported to the inner peripheral table 320 through the gap between the pair of partition walls 312.

[0059] Figure 5 is a three-sided view showing an example of the configuration of the reagent container 100 according to the first embodiment. Figure 5(A) is a left side view of the reagent container 100. Figure 5(B) is a front view of the reagent container 100. Figure 5(C) is a bottom view of the reagent container 100.

[0060] The reagent container 100 has a tapered shape in which its width gradually narrows from the left side to the right side. That is, the horizontal cross section of the reagent container 100 is wedge-shaped (trapezoidal). The reagent container 100 has 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 121, an engaging claw 122, and a notched surface 123. A rectangular fitting groove 130 is formed on the bottom surface of the adapter 120. The horizontal cross section of the reagent container 100 may also have a rectangular shape.

[0061] The reagent bottle 110 is a bottle that contains a reagent. The opening member 111 is a hollow member that has an opening formed therethrough, through which the first reagent dispensing probe 209 (see FIG. 2) is inserted. The main body 112 is a hollow member that contains a reagent. The opening member 111 and the main body 112 may be integrally molded.

[0062] The adapter 120 is a device that is detachably attached to the reagent bottle 110. The adapter 120 is attached to the underside of the reagent bottle 110. The frame 121 is a member shaped to fit the reagent bottle 110. The engagement claw 122 is an inverted L-shaped member that protrudes from the left side of the frame 121. The engagement claw 122 is engaged with the reagent container arm 220. The cutout surface 123 is a surface that slopes from the left side to the underside of the frame 121. The shape of the cutout surface 123 corresponds to the shape of the sloped surface of the sloped member 328.

[0063] The fitting grooves 130 are grooves having shapes corresponding to the outer peripheral rail 315 and the inner peripheral rail 325. The reagent containers 100 are fitted into the outer peripheral rail 315 and the inner peripheral rail 325 by the fitting grooves 130 formed on the lower surface of the adapter 120.

[0064] If the adapter 120 is not attached to the reagent bottle 110, a fitting groove 130 may be formed on the bottom surface of the reagent bottle 110. In this case, the reagent container 100 is considered to be the same as the reagent bottle 110. That is, the reagent container 100 (reagent bottle 110) fits into the outer circumferential rail 315 and the inner circumferential rail 325 via the fitting groove 130 formed on the bottom surface.

[0065] 6A and 6B are diagrams showing an example of transport of the reagent container 100 according to the first embodiment to the inner peripheral table 320. Fig. 6A is a front view showing the state in which the reagent container 100 has been transported to the outer peripheral table 310. Fig. 6B is a front view showing the state in which the reagent container 100 has been transported to the inner peripheral table 320.

[0066] 6(A), the reagent container arm 220 transports the reagent container 100 in direction D1 while contacting the left side surface of the reagent container 100. At this time, the fitting groove 130 of the reagent container 100 fits into the outer circumferential rail 315 with a certain amount of clearance. This fitting allows the reagent container arm 220 to transport the reagent container 100 accurately and smoothly along the direction in which the outer circumferential rail 315 extends.

[0067] As shown in FIG. 6(B), the reagent container arm 220 transports the reagent container 100, which has been transported to the outer circumferential table 310, to the inner circumferential table 320 in direction D1. At the step between the outer circumferential table 310 and the inner circumferential table 320, the reagent container 100 slides down the inclined surface of the inclined member 328 via the notched surface 123. At the same time, the fitting groove 130 of the reagent container 100 fits tightly into the inner circumferential rail 325. This fitting allows the reagent container arm 220 to transport the reagent container 100 accurately and smoothly along the direction in which the inner circumferential rail 325 extends.

[0068] As the inner circumferential table 320 rotates, a centrifugal force in the direction opposite to direction D1 is applied to the reagent container 100 transported to the inner circumferential table 320. At this time, the step between the outer circumferential table 310 and the inner circumferential table 320 prevents the reagent container 100 from being pushed back to the outer circumferential table 310 by the centrifugal force. In other words, the step can fix the reagent container 100 to the inner circumferential table 320.

[0069] 7A and 7B are diagrams showing an example of the transfer of the reagent container 100 according to the first embodiment from the inner peripheral table 320. Fig. 7A is a front view showing the state in which the reagent container 100 has been transferred to the inner peripheral table 320. Fig. 7B is a front view showing the state in which the reagent container 100 has been transferred to the outer peripheral table 310.

[0070] 7(A), the reagent container arm 220 transports the reagent container 100 in a direction D2 opposite to direction D1 while engaging with the engaging claws 122 of the reagent container 100. At the step between the outer peripheral table 310 and the inner peripheral table 320, the reagent container 100 slides up the inclined surface of the inclined member 328 via the notched surface 123. At the same time, the fitting groove 130 of the reagent container 100 fits into the outer peripheral rail 315 with a certain amount of clearance. This fitting allows the reagent container arm 220 to transport the reagent container 100 accurately and smoothly along the direction in which the outer peripheral rail 315 extends.

[0071] 7(B), the reagent container arm 220 transports the reagent container 100 in direction D2 while engaging with the engaging claws 122 of the reagent container 100. The reagent container arm 220 transports the reagent container 100 to the outside of the first reagent storage 204 through the opening 204H.

[0072] According to the first embodiment described above, the automatic analyzer 1 transports the reagent container 100 from the "side" of the first reagent storage 204, rather than from "above." Specifically, the automatic analyzer 1 transports the reagent container 100 held by the reagent container arm 220 into the first reagent storage 204 through the opening 204H formed in the housing 204A of the first reagent storage 204. On the other hand, the automatic analyzer 1 transports the reagent container 100 held by the reagent container arm 220 to the outside of the first reagent storage 204 through the opening 204H.

[0073] That is, the automated analyzer 1 pushes or pulls out the reagent container 100 held by the reagent container arm 220 in a horizontal direction through the opening 204H. At this time, the reagent container arm 220 does not need to move in a vertical direction, which simplifies the operation control or structure of the reagent container arm 220. Therefore, the automated analyzer 1 can reduce the cost of the entire device, including the reagent container arm 220.

[0074] (Modification of the first embodiment) FIG. 8 is a diagram showing an example of the configuration of reagent containers (100A, 100B, 100C, 100D) and rails (335A, 335B, 335C, 335D) according to a modified example of the first embodiment. FIG. 8(A) is a left side view of the reagent container 100A and rail 335A. FIG. 8(B) is a left side view of the reagent container 100B and rail 335B. FIG. 8(C) is a left side view of the reagent container 100C and rail 335C. FIG. 8(D) is a left side view of the reagent container 100D and rail 335D.

[0075] 8(A), a T-shaped fitting groove 130A is formed in the lower part of the reagent container 100A. The rail 335A is T-shaped to correspond to the shape of the fitting groove 130A. The rail 335A is an example of the outer circumferential rail 315 or the inner circumferential rail 325.

[0076] The reagent container arm 220 transports the reagent container 100A while fitting the fitting groove 130A of the reagent container 100A into the rail 335A. At this time, the shape of the rail 335A restricts the movement of the reagent container 100A so that it does not swing in the horizontal direction or the vertical direction. Therefore, the reagent container arm 220 can transport the reagent container 100A more stably along the direction in which the rail 335A extends. From another perspective, the T-shaped fitting groove 130A and rail 335A can prevent the reagent contained in the reagent container 100A from bubbling due to the swinging of the reagent container 100A.

[0077] As shown in Figure 8(B), a pair of rectangular mating grooves 130B are formed in the lower part of the reagent container 100B. One mating groove 130B has a shape that is the left-right mirror image of the other mating groove 130B. The pair of rails 335B each have an inverted L shape so as to fit into the pair of mating grooves 130B. The rails 335B are an example of the outer peripheral rail 315 or the inner peripheral rail 325.

[0078] The reagent container arm 220 transports the reagent container 100B while fitting the pair of fitting grooves 130B of the reagent container 100B into the pair of rails 335B. At this time, the shape of the pair of rails 335B restricts the movement of the reagent container 100B so that it does not swing in the horizontal direction or the vertical direction. Therefore, the reagent container arm 220 can transport the reagent container 100B more stably along the direction in which the pair of rails 335B extend. From another perspective, the pair of rectangular fitting grooves 130B and the pair of inverted L-shaped rails 335B can prevent bubbling of the reagent contained in the reagent container 100B caused by the swinging of the reagent container 100B.

[0079] As shown in FIG. 8(C), unlike the reagent container 100, the reagent container 100C does not have a fitting groove 130. The pair of rails 335C are each in an inverted L shape so as to sandwich the reagent container 100C horizontally. In particular, a portion of the pair of rails 335C is disposed so as to cover the upper surface of the main body 112 (frame 121). The rails 335C are an example of the outer peripheral rail 315 or the inner peripheral rail 325.

[0080] The reagent container arm 220 transports the reagent container 100C between the pair of rails 335C. At this time, the shape of the pair of rails 335C restricts the movement of the reagent container 100C so that it does not swing in the horizontal direction or the vertical direction. Therefore, the reagent container arm 220 can transport the reagent container 100C more stably along the direction in which the pair of rails 335C extends. From another perspective, the pair of rails 335C can prevent the reagent contained in the reagent container 100C from bubbling due to the swinging of the reagent container 100C.

[0081] 8(D), unlike the reagent container 100, the reagent container 100D does not have a fitting groove 130. A pair of rails 335D are arranged to sandwich the lower part of the reagent container 100D horizontally. The rails 335D are an example of the outer peripheral rails 315 or the inner peripheral rails 325.

[0082] The reagent container arm 220 transports the reagent container 100D between the pair of rails 335D. At this time, the movement of the reagent container 100D is restricted by the shape of the pair of rails 335D so that it does not swing horizontally. Therefore, the reagent container arm 220 can stably transport the reagent container 100D along the direction in which the pair of rails 335D extend. From another perspective, the pair of rails 335D can prevent bubbling of the reagent contained in the reagent container 100D, which would occur due to swinging of the reagent container 100D.

[0083] 8(D) restricts the horizontal swinging of the reagent container 100D. On the other hand, the engagement of the engagement groove 130 shown in FIG. 5(A) with the outer circumferential rail 315 or the inner circumferential rail 325 restricts the horizontal swinging of the reagent container 100D. In other words, the pair of rails 335D provides an effect similar to that provided by the engagement of the engagement groove 130 with the outer circumferential rail 315 or the inner circumferential rail 325.

[0084] (Second embodiment) 9A and 9B are diagrams showing an example of the configuration of each table and a reagent container 100G according to the second embodiment. Fig. 9A is a front view of the outer peripheral table 310 and the inner peripheral table 320. Fig. 9B is a front view of the reagent container 100G.

[0085] 9(A), the outer peripheral table 310 has a protrusion member 316 at one end adjacent to the inner peripheral table 320. The inner peripheral table 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 or semicircular). The protrusion members 316 and 326 are formed to a predetermined size so that the reagent container 100G can ride up and fit into them.

[0086] 9(B), a fitting groove 140 is formed in the lower surface near the right side of the reagent container 100G. The fitting groove 140 has a shape corresponding to the protruding members 316 and 326.

[0087] 10A and 10B are diagrams showing an example of transport of a reagent container 100G to each table according to the second embodiment. Fig. 10A is a front view showing a state in which the reagent container 100G has been transported to the outer peripheral table 310. Fig. 10B is a front view showing a state in which the reagent container 100G has been transported to the inner peripheral table 320.

[0088] 10(A), the reagent container arm 220 transports the reagent container 100G in 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 rides up and fits onto the protruding member 316. By fitting, the reagent container 100G is fixed to the peripheral table 310.

[0089] As the outer periphery table 310 rotates, a centrifugal force in the direction opposite to direction D1 is applied to the reagent container 100G transported to the outer periphery table 310. At this time, the engagement between the engagement groove 140 and the protrusion member 316 prevents the reagent container 100G from being pushed back to the outside through the opening 204H due to the centrifugal force. In other words, this engagement fixes the reagent container 100G to the outer periphery table 310.

[0090] 10(B), the reagent container arm 220 transports the reagent container 100G fixed to the outer peripheral table 310 along direction D1 to the inner peripheral table 320. At this time, the fitting groove 140 of the reagent container 100G disengages from the protruding member 316 and rides up to fit onto the protruding member 326. By fitting, the reagent container 100G is fixed to the inner peripheral table 320.

[0091] As the inner circumferential table 320 rotates, a centrifugal force in the direction opposite to direction D1 is applied to the reagent container 100G transported to the inner circumferential table 320. At this time, the engagement between the engagement groove 140 and the protrusion member 326 prevents the reagent container 100G from being pushed back into the outer circumferential table 310 by the centrifugal force. In other words, this engagement can fix the reagent container 100G to the inner circumferential table 320.

[0092] The reagent container 100G according to the second embodiment is transported to the outside of the first reagent storage 204 in the same manner as in the first embodiment. That is, the reagent container arm 220 transports the reagent container 100G along a direction D2 opposite to the direction D1 while engaging with the engaging claws 122 of the reagent container 100G (see FIG. 7).

[0093] According to the second embodiment described above, the automatic analyzer 1 achieves the same effects as the first embodiment. Furthermore, the automatic analyzer 1 can fix the reagent container 100G to the outer peripheral table 310 or the inner peripheral table 320 by fitting the fitting groove 140 of the reagent container 100G into the protruding member 316 or 326.

[0094] (Third embodiment) Figure 11 shows an example of the configuration of each table and each reagent container according to the third embodiment. Figure 11(A) is a front view of the outer peripheral table 310 and the inner peripheral table 320. Figure 11(B) is a front view of the reagent container 100P (first reagent container). Figure 11(C) is a front view of the reagent container 100Q (second reagent container).

[0095] As shown in Figure 11(A), the outer periphery table 310 has a magnet 400A (first magnet). The magnet 400A is arranged in the center of the outer periphery table 310. The inner wall 320A has a magnet 400B (second magnet). The magnet 400B is arranged in the center of the inner wall 320A.

[0096] 11(B), a magnetic body 500P (first magnetic body) is disposed in the center of the bottom surface of the reagent container 100P. The magnetic body 500P may be a member made of a ferromagnetic material such as iron, cobalt, or nickel. Typically, the magnetic body 500P is an iron plate.

[0097] 11(C), a magnetic body 500Q (second magnetic body) is disposed in the center of the right side surface of the reagent container 100Q. The magnetic body 500Q may be a member made of a ferromagnetic material such as iron, cobalt, or nickel. Typically, the magnetic body 500Q is an iron plate.

[0098] 12A and 12B are diagrams showing an example of transport of each reagent container to each table according to the third embodiment. Fig. 12A is a front view showing a state in which the reagent container 100P has been transported to the outer peripheral table 310. Fig. 12B is a front view showing a state in which the reagent container 100Q has been transported to the inner peripheral table 320.

[0099] 12(A), the reagent container arm 220 transports the reagent container 100P in direction D1 while contacting the left side surface of the reagent container 100P. At this time, a magnetic attraction force is generated between the magnet 400A of the outer periphery table 310 and the magnetic body 500P of the reagent container 100P. The attraction force fixes the reagent container 100P to the outer periphery table 310.

[0100] As the outer periphery table 310 rotates, a centrifugal force in the direction opposite to direction D1 is applied to the reagent container 100P transported to the outer periphery table 310. At this time, the attraction between the magnet 400A and the magnetic body 500P prevents the reagent container 100P from being pushed back to the outside through the opening 204H due to the centrifugal force. In other words, this attraction can fix the reagent container 100P to the outer periphery table 310.

[0101] 12(B), the reagent container arm 220 transports the reagent container 100Q in direction D1 while contacting the left side surface of the reagent container 100Q. At this time, a magnetic attraction force is generated between the magnet 400B on the inner wall 320A and the magnetic body 500Q of the reagent container 100Q. The attraction force fixes the reagent container 100Q to the inner peripheral table 320 adjacent to the inner wall 320A.

[0102] As the inner circumferential table 320 rotates, a centrifugal force in the direction opposite to direction D1 is applied to the reagent container 100Q transported to the inner circumferential table 320. At this time, the attraction between the magnet 400B and the magnetic body 500Q prevents the reagent container 100Q from being pushed back to the outer circumferential table 310 by the centrifugal force. In other words, this attraction can fix the reagent container 100Q to the inner circumferential table 320.

[0103] The reagent containers 100P and 100Q according to the third embodiment are transported to the outside of the first reagent storage 204 in the same manner as in the first embodiment. That is, the reagent container arm 220 transports the reagent container 100P in a direction D2 opposite to direction D1 while engaging with the engaging claws 122 of the reagent container 100P. The reagent container arm 220 transports the reagent container 100Q in direction D2 while engaging with the engaging claws 122 of the reagent container 100Q (see FIG. 7).

[0104] Here, it is assumed that the reagent container arm 220 transports the reagent container 100Q fixed to the inner peripheral table 320 along direction D2. In this case, the reagent container arm 220 peels off the magnetic body 500Q attracted to the magnet 400B along direction D2. Next, the reagent container arm 220 transports the reagent container 100Q to the outside of the first reagent storage 204 via the outer peripheral table 310.

[0105] When the reagent container 100Q passes over the peripheral table 310, a certain distance is maintained between the magnet 400A of the peripheral table 310 and the magnetic body 500Q of the reagent container 100Q. This distance is greater than the distance between the magnet 400A of the peripheral table 310 and the magnetic body 500P of the reagent container 100P. Therefore, the reagent container 100Q is not attracted to the magnet 400A as much as the reagent container 100P, and is transported smoothly.

[0106] The inner peripheral table 320 may have a magnet 400B in the center, similar to the outer peripheral table 310. In this case, the reagent container 100Q may have a magnetic body 500Q in the center of the bottom surface, similar to the reagent container 100P. In other words, the reagent container 100Q may have the same configuration as the reagent container 100P.

[0107] In the above case, the reagent container arm 220 transports the reagent container 100Q to the inner peripheral table 320 while contacting the left side surface of the reagent container 100Q. At this time, a magnetic attraction force is generated between the magnet 400B of the inner peripheral table 320 and the magnetic body 500Q of the reagent container 100Q. The attraction force fixes the reagent container 100Q to the inner peripheral table 320.

[0108] According to the third embodiment described above, the automatic analyzer 1 achieves the same effects as the first embodiment. Furthermore, the automatic analyzer 1 can fix the reagent container 100P to the outer circumferential table 310 by the attractive force between the magnet 400A on the outer circumferential table 310 and the magnetic body 500P of the reagent container 100P. The automatic analyzer 1 can fix the reagent container 100Q to the inner circumferential table 320 by the attractive force between the magnet 400B on the inner wall 320A and the magnetic body 500Q of the reagent container 100Q.

[0109] (Each embodiment) 13A and 13B are top views showing examples of rotation control of each table according to each embodiment. Fig. 13A is a top view of the outer peripheral table 310 and the inner peripheral table 320 before rotation. Fig. 13B is a top view of the outer peripheral table 310 and the inner peripheral table 320 after rotation.

[0110] 13(A), on the outer circumferential table 310 and the inner circumferential table 320, multiple reagent containers 100 are arranged at equal intervals on a circumference around the rotation center P. In other words, the multiple reagent containers 100 are arranged point-symmetrically with respect to the rotation center P. This arrangement applies a uniform load to each position on the outer circumferential table 310 or the inner circumferential table 320. Therefore, this arrangement can reduce vibrations that accompany the rotation of the outer circumferential table 310 or the inner circumferential table 320.

[0111] Here, two reagent containers 100 are arranged in a direction D1 (see FIG. 3) from the opening 204H toward the rotation center P. Specifically, in the direction D1, a reagent container 100 is arranged in a space 311 on the outer peripheral table 310, and another reagent container 100 is arranged in a space 321 on the inner peripheral table 320. In this case, the automated analyzer 1 needs to rotate the outer peripheral table 310 and the inner peripheral table 320 to transport the reagent container 100 to the empty space 321 on the inner peripheral table 320.

[0112] For example, the automatic analyzer 1 uses the identification function 91 to identify the empty space 311 on the outer circumferential table 310 that is closest to the position of the opening 204H. When the outer circumferential table 310 rotates clockwise, the identification function 91 identifies the space 311E as this empty space 311.

[0113] Similarly, the automated analyzer 1 identifies an empty space 321 on the inner circumferential table 320 that is closest to the position of the opening 204H using the identification function 91. When the inner circumferential table 320 rotates clockwise, the identification function 91 identifies space 321E as this empty space 321.

[0114] Next, the automatic analyzer 1 uses the system control function 92 and the drive mechanism 4 to rotate the outer circumferential table 310 so that the space 311E identified by the identification function 91 approaches (is adjacent to) the position of the opening 204H.

[0115] Similarly, the automatic analyzer 1 rotates the inner circumferential table 320 using the system control function 92 and the drive mechanism 4 so that the space 321E identified by the identification function 91 approaches the position of the opening 204H.

[0116] 13(B), the automated analyzer 1 rotates the outer peripheral table 310 in direction DR1 and rotates the inner peripheral table 320 in direction DR2. As a result of the rotation of each table, spaces 311E and 321E are positioned in direction D1. The automated analyzer 1 transports the reagent container 100 to space 321E using the reagent container arm 220 through the opening 204H and space 311E.

[0117] Through the above operation, the automatic analyzer 1 minimizes the rotation distance (rotation angle) of the outer peripheral table 310 and the inner peripheral table 320. Therefore, the automatic analyzer 1 can quickly transport the reagent container 100 held by the reagent container arm 220 to the empty space 321 on the inner peripheral table 320. Furthermore, the automatic analyzer 1 can prevent the reagent contained in the multiple reagent containers 100 placed on the outer peripheral table 310 or the inner peripheral table 320 from bubbling.

[0118] (Other variations) First, the automatic analyzer 1 may rotate the outer peripheral table 310 or the inner peripheral table 320 so that the predetermined empty space 311 or 321 selected by the operator via the input IF 6 approaches the position of the opening 204H. In this case, the automatic analyzer 1 can transport the reagent container 100 to the empty space 311 or 321 desired by the operator.

[0119] Second, the automated analyzer 1 may use the identification function 91 to identify the distance from the position of the opening 204H to the space 311E or 321E. The distance may be the "straight-line distance" from the position of the opening 204H to the space 311E or 321E. Alternatively, the distance may be the "rotation distance" (rotation angle) of the outer circumferential table 310 or the inner circumferential table 320 required to move the space 311E or 321E closer to the position of the opening 204H.

[0120] In this case, the automatic analyzer 1 may use the system control function 92 and the drive mechanism 4 to change the speed at which the outer circumferential table 310 or the inner circumferential table 320 rotates depending on the distance. For example, the shorter the distance, the faster the automatic analyzer 1 rotates the outer circumferential table 310 or the inner circumferential table 320. This allows the automatic analyzer 1 to quickly move the space 311E or 321E, which is relatively close to the position of the opening 204H, closer to the position of the opening 204H. On the other hand, the automatic analyzer 1 can move the space 311E or 321E, which is relatively far from the position of the opening 204H, closer to the position of the opening 204H so as to prevent the reagent contained in each reagent container 100 from foaming.

[0121] Third, the automatic analyzer 1 may use the identification function 91 to identify empty spaces 311 or 321 (installation spaces) in which the reagent containers 100 can be installed so that multiple reagent containers 100 are installed at equal intervals around the circumference of the outer peripheral table 310 or the inner peripheral table 320. For example, the identification function 91 identifies whether a pair of reagent containers 100 is installed for each pair of spaces 311 or 321 that are arranged point-symmetrically with respect to the center of rotation P. For a specific pair of spaces 311 or 321, if a reagent container 100 is installed only in one space 311, the identification function 91 identifies the other space 311 as the empty space 311 or 321.

[0122] In this case, the automatic analyzer 1 transports the reagent container 100 to the empty space 311 or 321 using the reagent container arm 220. This allows the automatic analyzer 1 to arrange multiple reagent containers 100 at equal intervals on the outer peripheral table 310 or the inner peripheral table 320. In other words, the automatic analyzer 1 achieves the effects described above (see FIG. 13(A)).

[0123] Fourth, the automated analyzer 1 may transport the reagent container 100 in a lifted state to the inner peripheral table 320 by the reagent container arm 220 without placing the reagent container 100 on the outer peripheral table 310. In other words, the reagent container arm 220 may place the lifted reagent container 100 on the inner peripheral table 320 without bringing the reagent container 100 into contact with the outer peripheral table 310.

[0124] Fifth, the outer circumferential table 310 may have at least one empty space in which a reagent container 100 is not placed. The empty space may be formed in the shape of a straight passage. The empty spaces may be formed at equal intervals on the circumference of the outer circumferential table 310. Specifically, with respect to an angle θ (°) around the rotation center P, the empty spaces may be formed at θ / 360 (locations) for each angle θ. For example, when the angle θ is 180, 120, or 90, the empty spaces are formed at equal intervals in two, three, or four locations, respectively. The automated analyzer 1 may transport the reagent container 100 to the inner circumferential table 320 by the reagent container arm 220 through the empty space formed on the outer circumferential table 310.

[0125] Let us assume that the outer circumferential table 310 has only a plurality of spaces for placing the reagent containers 100, and all of the spaces are filled with reagent containers 100. In this case, there is no free space on the outer circumferential table 310, and therefore the reagent container arm 220 cannot transport the reagent container 100 to the inner circumferential table 320 through the free space.

[0126] On the other hand, if the outer peripheral table 310 has at least one empty space in which a reagent container 100 is not placed, the reagent container arm 220 can transport the reagent container 100 to the inner peripheral table 320 through that empty space. In other words, the outer peripheral table 310 has an empty space dedicated to transporting the reagent container 100 to the inner peripheral table 320, so that the reagent container 100 can move freely between the outer peripheral table 310 and the inner peripheral table 320.

[0127] According to at least one of the embodiments described above, the structure of the automatic analyzer can be simplified.

[0128] Although several embodiments have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These embodiments can be implemented in various other forms, and various omissions, substitutions, modifications, and combinations of embodiments can be made without departing from the spirit of the invention. These embodiments and their modifications are included within the scope and spirit of the invention, as well as within the scope of the invention and its equivalents as defined in the claims.
