Abstract

The present invention is one for achieving an improvement in analysis accuracy, and a sample analyzing device that measures light emitted by introducing a reagent to a sample contained in a container to analyze the sample, and the sample analyzing device includes: a holder that holds the container; a casing that has a door for taking in/out the holder; a nozzle to/from which a pipette tip for injecting the reagent into the container can be attached/detached; a photodetector that measures the light emitted from the sample in the container supported by the holder; and a disposal box into which the pipette tip after injection is disposed of, in which the disposal box is configured to be arranged in the casing and to be taken in/out via the door.

First claim

1 . A sample analyzing device that measures light emitted by introducing a reagent to a sample contained in a container analyze the sample, the sample analyzing device comprising:
a holder that holds the container; a casing that has a door for taking in/out the holder; a nozzle to/from which a pipette tip for injecting the reagent into the container can be attached/detached; a photodetector that measures the light emitted from the sample in the container supported by the holder; and a disposal box into which the pipette tip after injection is disposed of, wherein the disposal box is configured to be arranged in the casing and to be taken in/out via the door.

2 . The sample analyzing device according to claim 1 , wherein
the disposal box is provided to the holder.

3 . The sample analyzing device according to claim 2 , wherein
the holder is one that holds multiple containers, as well as holds them in a ring-shaped manner, and the disposal box is provided on an inner side of the multiple containers in the holder.

4 . The sample analyzing device according to claim 3 , wherein
the holder is one that holds the multiple containers in a circular ring-shaped manner, and the disposal box has an arc-shaped opening along an arrangement direction of the multiple containers in a plan view.

5 . The sample analyzing device according to claim 1 , wherein
in the disposal box, a disposal space is separated for each pipette tip to be disposed of.

6 . The sample analyzing device according to claim 5 , wherein
the disposal space has: an opening part opened in an upper surface of the disposal box; and a narrowed part that is formed below the opening part and whose opening area is smaller than the opening part.

7 . The sample analyzing device according to claim 5 , comprising:
a holding unit that holds the nozzle, as well as moves in a horizontal direction; a tip detachment member that is provided to the holding unit to move together with the nozzle, and moves between a detachment position to detach the pipette tip attached to the nozzle and a withdrawal position withdrawn therefrom; and an actuator that, in a state where the holding unit is in a predetermined position, operates the tip detachment member to move the tip detachment member from the withdrawal position to the detachment position.

8 . The sample analyzing device according to claim 1 , comprising
a detection mechanism that detects presence or absence of the disposal box in the casing.
