Abstract
The gas supply device disclosed in the present specification includes a cover that shuts off the periphery of the main stop valve and the connector of the gas cartridge from the outside air, and a removal device that removes impurities from the inner space of the cover in a state where the connector and the main stop valve are not connected. The controller of the gas supply device connects the main stop valve and the connector when impurities are removed from the inner space by the removal device, and opens the main stop valve. The gas supply device disclosed herein shuts off the periphery of the main stop valve and the connector from the outside air and removes impurities from the periphery of the main stop valve. Therefore, contamination of the gas supply device with impurities can be suppressed.
