Furthermore, since the sub-module can be quickly moved to the exchange position by driving the endless chain,
The replacement work of the auxiliary module can be performed simply and quickly.

According to the sixth aspect of the present invention, since the sub-module can be moved with a small operating force by the levitating device, the replacement operation of the sub-module can be performed simply and quickly. Furthermore, if clean air is used for the compressed air, the coating equipment in a clean environment will not be contaminated. According to the present invention, since the position of the sub-module suspended by the suspender can be changed by moving the trolley, the replacement operation of the sub-module can be performed simply and quickly.
