  A smearing operation by the smearing unit 22 is performed in parallel with the suction dispensing operation by the suction dispensing mechanism unit 21 or after the suction dispensing operation. The smearing unit 22 supplies the slide glass 10 to the dispensing / smearing position 90 (see FIG. 3), and smears the blood dropped on the slide glass 10 and dries it. Then, after the blood sample information is printed on the slide glass 10, the printed slide glass 10 is moved to the slide glass insertion portion 26 side. Next, the cassette 23 set in the cassette housing portion 24 shown in FIG. 3 is sent to the transport path 25b of the cassette transport portion 25 by the feed belt 24a. And it is conveyed to the slide glass insertion part 26 by the cassette conveyance member 25a of the cassette conveyance part 25. FIG.

  In the slide glass insertion portion 26 shown in FIG. 3, first, it is determined whether or not the slide glass 10 is stored in the slide glass storage hole 23 a of the cassette 23. When it is determined that the slide glass 10 is stored in the cassette 23, the cassette 23 is moved to the staining unit 27 along the transport path 25b by the cassette transport member 25a as it is. In this case, the cassette 23 is moved to the storage unit 28 without being stained by the staining unit 27. When the slide glass insertion unit 26 determines that the slide glass 10 is not stored in the slide glass storage hole 23a of the cassette 23, the slide glass insertion unit 26 inserts the slide glass 10 into the cassette 23. Then, the cassette 23 in which the smeared slide glass 10 is stored is transported to the staining unit 27 by the cassette transport member 25a.

  In the staining unit 27 according to the present embodiment, the cassette 23 is transported by the transport belt 27a, and in the first suction discharge unit 27b to the fifth suction discharge unit 27f, the staining liquid and the cleaning water are sequentially supplied to the cassette 23. By dispensing and sucking and discharging the staining liquid suction / dispensing hole 23b, the stained glass slide 10 of the cassette 23 is stained. Further, as shown in FIG. 6, a liquid such as a staining solution used for the staining process of the slide glass 10 is temporarily stored in the chamber 81 and then dispensed from the supply pipette 71 into the cassette 23.

  Here, referring to FIG. 6, among the operations of the first to fifth suction / discharge sections 27b to 27f described above, the staining solution dispensed into the cassette 23 in the third suction / discharge section 27d is temporarily stored. The suction operation and discharge operation of the chamber 81 will be described.

  First, when the suction operation of the chamber 81 is performed, the valve 86 shown in FIG. 6 is opened, the valve 88 is shut off, and the valve 87 has a flow path between the chamber 81 and the mixing chamber 83. Turn off. Then, the inside of the chamber 81 is depressurized by the atmospheric pressure regulator 82. Thereby, the staining solution in the container 80 moves into the chamber 81. Along with the inflow of the staining solution, the floating member 81d of the float switch 81b installed in the chamber 81 moves upward. Then, when the float switch 81b is turned on, the pressure reduction by the pressure regulator 82 is released, and the staining liquid suction operation by the chamber 81 is completed.

  Next, when moving the staining solution in the chamber 81 to the mixing chamber 83, the valves 86 and 88 are shut off, and the flow path between the chamber 81 and the diaphragm pump 87 is opened in the valve 87. To. Then, the inside of the diaphragm pump 84 is depressurized by the atmospheric pressure regulator 85. Thereby, a certain amount of the staining liquid in the chamber 81 is sucked into the diaphragm pump 84. Thereafter, in the valve 87, the flow path between the diaphragm pump 84 and the mixing chamber 83 is opened. Then, the inside of the diaphragm pump 84 is pressurized by the atmospheric pressure regulator 85. As a result, the staining liquid in the diaphragm pump 84 moves to the mixing chamber 83 by a certain amount. The staining solution is diluted in the mixing chamber 83 and then supplied into the cassette 23 from the supply pipette 71 of the third suction / discharge unit 27d.

  Further, when the discharge operation of the chamber 81 is performed, the valve 86 is shut off, the valve 88 is opened, and the flow path between the chamber 81 and the mixing chamber 83 is shut off at the valve 87. . Then, the inside of the chamber 81 is pressurized by the atmospheric pressure regulator 82. Thereby, the dyeing liquid in the chamber 81 is discharged out of the apparatus from the discharge port. Along with the outflow of this staining solution, the floating member 81d of the float switch 81b installed in the chamber 81 moves downward. Then, when the float switch 81b is turned off, the pressurization by the atmospheric pressure regulator 82 is released, and the discharge operation of the staining liquid by the chamber 81 ends.
