Container, container partition plate, substrate processing system, and substrate transfer method

1. A container for consumables, comprising:

an inner wall;

multiple holding portions configured to respectively accommodate the consumables, each of which is loaded and unloaded in one direction;

a partition plate including a first portion formed to be disposed between a light emitting part of a detector and a light receiving part of the detector, wherein the partition plate is accommodated in one of the multiple holding portions; and

a fixer configured to fix the container so that the consumables are arranged on a transfer path to be loaded into and unloaded from the multiple holding portions,

wherein the partition plate comprises a sealing portion formed at an outer periphery of the partition plate,

wherein the outer periphery of the partition plate has a vertically extending outwardly facing outer peripheral shape corresponding to a vertically extending inwardly facing inner peripheral shape of the inner wall of the container, and the outer periphery of the partition plate is in contact with the inner wall of the container via the sealing portion along the inner wall of the container, so that the vertically extending outwardly facing outer peripheral shape of the partition plate contacts the vertically extending inwardly facing inner peripheral shape of the inner wall of the container and the partition plate separates an inner space of the container into a first space including a part of the multiple holding portions and a second space including the other part of the multiple holding portions, and

wherein the container defines an enclosure which is configured to enclose the inner space of the container when a lid is closed, and contact the between the partition plate and the inner wall maintains the first space separate from the second space in the enclosure.

2. The container of claim 1 , wherein the partition plate has a thickness greater than a thickness of a substrate.

3. The container of claim 1 , wherein the partition plate has substantially the same thickness as a thickness of the consumables.

4. The container of claim 1 , wherein the first portion is disposed between two notches of the partition plate, the two notches having shapes corresponding to shapes of the light emitting part and the light receiving part, respectively.

5. The container of claim 2 , wherein the partition plate has substantially the same thickness as a thickness of the consumables.

6. The container of claim 2 , wherein the first portion is disposed between two notches of the partition plate, the two notches having shapes corresponding to shapes of the light emitting part and the light receiving part, respectively.

7. The container of claim 5 , wherein the first portion is disposed between two notches of the partition plate, the two notches having shapes corresponding to shapes of the light emitting part and the light receiving part, respectively.

8. The container of claim 3 , wherein the first portion is disposed between two notches of the partition plate, the two notches having shapes corresponding to shapes of the light emitting part and the light receiving part, respectively.

9. The container of claim 1 , wherein the container includes an opening, and the partition plate is accommodated in one of the multiple holding portions in a mounted position, and

wherein the partition plate includes a first notch and a second notch which face toward the opening of the container in the mounted position.

10. The container of claim 9 , wherein the first portion of the partition plate is between the first notch and the second notch, and the first portion includes a curved portion which protrudes toward the opening in the mounted position.
