The specimen chamber and the nozzle chamber are separated by a gate valve. In the nozzle chamber, at least a tip opening of a nozzle that ejects a specimen is present. A control device maintains a relationship of gas pressures such that a gas pressure in the specimen chamber is higher than a gas pressure in the nozzle chamber when the lower-side structure and the upper-side structure are in communication with each other.
