Microscope device

1. A microscope device comprising:

a sample container holder that is capable of housing a plurality of sample containers and that is supported so as to be attachable, each of the sample containers housing a sample and a first immersion medium and including a transparent section that transmits light;

an illumination optical system that emits illumination light to the sample via the transparent section;

a detection optical system that detects light from the sample via the transparent section; and

a movement mechanism that relatively moves the sample container holder, the detection optical system, and the illumination optical system in a first direction that is orthogonal to an optical axis of the illumination optical system and that is orthogonal to the optical axis of the detection optical system, the first direction being a gravity direction when the microscope device is mounted on a horizontal mounting surface, wherein

the sample container holder stacks and houses the plurality of sample containers in the first direction.

2. The microscope device according to claim 1 , further comprising:

a medium container that stores a second immersion medium that has a refractive index that is almost identical to that of the first immersion medium, and that immerses the sample holder with the second immersion medium, wherein

the medium container includes a second transparent section that transmits light,

the illumination optical system emits the illumination light to the sample via the second transparent section and the transparent section, and

the detection optical system detects the light from the sample via the second transparent section and the transparent section.

3. The microscope device according to claim 2 , wherein

the sample container holder and the medium container are configured so as not to relatively move in the first direction.

4. The microscope device according to claim 3 , wherein

the movement mechanism is connected to the sample container holder and the medium container.

5. The microscope device according to claim 1 , further comprising:

a second movement mechanism that rotationally moves the sample container holder with the first direction as an axis.

6. The microscope device according to claim 1 , further comprising:

a presser that presses, in the first direction, the plurality of sample containers that have been stacked in the first direction and have been housed in the sample container holder.

7. The microscope device according to claim 6 , wherein

the presser includes an elastic body, and

the plurality of sample containers are pressed in the first direction by using an elastic force of the elastic body.

8. The microscope device according to claim 1 , wherein

the sample container holder includes a third transparent section, and houses the plurality of sample containers in an airtight state,

the illumination optical system emits the illumination light to the sample via the third transparent section and the transparent section, and

the detection optical system detects the light from the sample via the third transparent section and the transparent section.

9. The microscope device according to claim 1 , further comprising:

a third movement mechanism that rotationally moves with an axis of the first direction as a center; and

a plurality of the sample container holders, wherein

the sample container holder to be arranged on optical paths of the illumination optical system and the detection optical system is switched from among the plurality of the sample container holders due to a movement of the third movement mechanism.

10. The microscope device according to claim 1 , wherein

the illumination optical system emits the illumination light to the sample from a second direction that is orthogonal to both the first direction and a direction of the optical axis of the detection optical system.
