Abstract: An expansion/compression mechanism of a piston rod assembly is composed of a bush shaft, a first cylindrical piston rod that is screwed with the bush shaft, a second cylindrical piston rod that is screwed with the first piston rod, and a piston rod holding member for housing the bush shaft and these piston rods. Therefore, the piston rods move linearly in multiple stages.

Abstract: A protective cap 2 is engaged with a latch 10 of a diluent container 5 so as to fix the diluent container 5 at a liquid holding position of a diluent container containing section 11. The engagement is released when the protective cap 2 is set to an open position against the engagement so as to expose an inlet 13. When the protective cap 2 is shifted from the open position to a closed position, the protective cap 2 pushes the diluent container 5 into a liquid discharge position. Thus, it is possible to preserve a diluent for a long period of time and to easily open the diluent container 5 without having to complicate the structure of an analysis apparatus.

Abstract: An analyzing device configured to separate a solution component 18a in a separating cavity 23, which is connected to a measuring cavity through a connecting channel 37 and a measurement channel 38. A first capillary cavity 33 is provided on one side of the separating cavity 23 so as to communicate with the connecting channel 37. The first capillary cavity 33 is formed to extend to the outside of a separation interface 18c of a sample liquid separated in the separating cavity 23.

Abstract: An analyzing device includes: an operation cavity that is adjacent to a first reserving cavity retaining a sample liquid; a connecting section provided on a side wall of the first reserving cavity to suck the sample liquid by a capillary force and transfer the sample liquid to the operation cavity; and second reserving cavities that are disposed outside the operation cavity in the circumferential direction of the rotational driving and communicate with the outermost position of the operation cavity through a connecting passage. The connecting section is circumferentially extended farther than the liquid level of the sample liquid retained in the first reserving cavity.

Abstract: Provided is a panel (3) for analysis having a chamber inside for transferring a sample liquid dispensed as a drop on an injection port (14). The injection port (14) is formed to protrude in a direction away from the chamber, a recessed section (12) is formed around the injection port (14), and the injection port (14) is arranged on the side of a rotating axis center (11) of a holding member (101) for the panel for analysis in an analyzer. Thus, even when a sample liquid is adhered around the injection port, contamination and shortage of the sample liquid can be prevented.

Abstract: An analyzing device includes: an operation cavity (245) that is adjacent to a first reserving cavity (243) retaining a sample liquid, in a circumferential direction of rotational driving; a connecting section (255) provided on a side wall of the first reserving cavity (243) to suck the sample liquid by a capillary force and transfer the sample liquid to the operation cavity (245); and second reserving cavities (247, 248) that are disposed outside the operation cavity (245) in the circumferential direction of the rotational driving and communicate with the outermost position of the operation cavity (245) through a connecting passage (256). The connecting section (255) is circumferentially extended farther than the liquid level of the sample liquid retained in the first reserving cavity (243). Thus it is possible to reduce the quantity of the sample liquid, eliminate irregular agitation of a sample liquid and reagents, and reduce the size of an analyzing device.

Abstract: A measurement cell (40a) is formed so as to extend in a direction along which a centrifugal force is applied, and a capillary area (47a) to which a sample liquid is sucked by a capillary force is formed on one of the side walls of the measurement cell (40a), the side walls being arranged in a rotational direction. The capillary area (47a) extends from the outer periphery position to the inner periphery of the measurement cell (40a), thereby reducing the size of an analyzing device. Further, the sample liquid in the measurement cell (40a) is sucked to the capillary area (47a) by slowing or stopping a rotation, and then the rotation is accelerated to return the sample liquid in the capillary area (47a) to the measurement cell (40a). It is therefore possible to achieve a sufficient agitating effect and conduct measurement with a small quantity of sample liquid.

Abstract: A capillary cavity 19 and an inlet 13 protruding circumferentially outward from an axial center 107 are connected by a guide section 17 formed so as to extend circumferentially inward and on which a capillary force acts. A sample liquid collected from a leading end of the inlet 13 is transferred to a separation cavity 23. A bent section 22 and a recess 21 are formed at a connected section of the guide section 17 and the capillary cavity 19 so as to change the direction of a passage.
