Abstract

A culture apparatus includes an inner box for housing a culture, an outer box surrounding the inner box, and a first vibration prevention mechanism that is disposed between the inner box and the outer box, and is configured to prevent the inner box from vibrating due to the vibration of the outer box.

Claims (30)

1 . A culture apparatus, comprising:

an inner box for housing a culture;

an outer box surrounding the inner box; and

a first vibration prevention mechanism disposed between the inner box and the outer box,

wherein the first vibration prevention mechanism is configured to prevent the inner box from vibrating due to vibration of the outer box,

the first vibration prevention mechanism includes a plurality of plates and a plurality of spheres,

the plurality of plates includes a first plate fixed to the inner box and a second plate fixed to the outer box, and the rest of the plurality of plates are disposed between the first plate and the second plate,

the plurality of spheres are rotatably disposed between the plurality of plates,

the plurality of spheres are configured to rotate to move an upper plate of the plurality of plates with respect to a lower plate of the plurality of plates, and

the upper plate and the lower plate are two plates of the plurality of plates directly facing each other.

2 . The culture apparatus according to claim 1 , further comprising:

a first state switcher configured to allow the first vibration prevention mechanism to switch between states, wherein, in one state of the states, the first vibration prevention mechanism allows fixing of the inner box to the outer box, and in another state of the states, the fixing of the inner box to the outer box is released so that the first vibration prevention mechanism prevents the inner box from vibrating due to the vibration of the outer box.

3 . The culture apparatus according to claim 2 , further comprising:

an inner door configured to open and close the inner box;

an outer door configured to open and close the outer box;

an opening/closing detector configured to detect an opened or closed state of at least one door of the inner door and the outer door; and

a controller that controls, when the opening/closing detector detects that the at least one door is opened, the first state switcher to allow the first vibration prevention mechanism to switch from the other state, in which the first vibration prevention mechanism prevents the inner box from vibrating due to the vibration of the outer box, to the one state, in which the first vibration prevention mechanism allows the fixing of the inner box to the outer box.

4 . The culture apparatus according to claim 2 , wherein

the first state switcher includes a first switching member and a first switching driver,

the first switching member includes a first contact part extending in vertical direction and a first rotation restricting part extending in horizontal direction from a lower end of the first contact part, and

the first switching driver is configured to rotate the first switching member about a first rotation shaft.

5 . The culture apparatus according to claim 1 , further comprising:

a sealing member surrounding an opening of the inner box and extending between the inner box and the outer box, the sealing member sealing a space between the inner box and the outer box.

6 . The culture apparatus according to claim 1 , further comprising:

a shelf disposed inside the inner box; and

a second vibration prevention mechanism disposed between the inner box and the shelf,

the second vibration prevention mechanism being configured to prevent the shelf from vibrating due to vibration of the inner box.

7 . The culture apparatus according to claim 6 , wherein:

the second vibration prevention mechanism is a vibration control mechanism.

8 . The culture apparatus according to claim 6 , wherein the second vibration prevention mechanism includes a plurality of vibration control members that support the shelf, and the plurality of vibration control members are made of rubber, oil dampers, or air dampers.
