Abstract
Problem: To provide a mass spectrometer wherein the door can be easily opened even when the door becomes stuck to a third wall surface. Solution: A mass spectrometer comprising a doorcan be opened and closed and a leverhaving a straight-shaped sectionthat is rotatable about a rotation shaft that is perpendicular to a first edge, wherein the rotation in a forward direction of one end of the straight-shaped sectionof the leverby a person taking measurements when the dooris closed causes a male partformed on the leverto interfere with and become locked with a female partthat is formed on an enclosure, thus making the doorunopenable and unclosable while the rotation in a reverse direction of the one end of the straight-shaped sectionof the lever by a person taking measurements creates an unlocked state that allows the doorto be opened and closed and the other end of said straight-shaped sectionof the leverpresses against a part of a third wall surfacethat creates a force to open the door
