Claims

[Scope of utility model registration request]

(1) A probe that introduces a sample into the ion source chamber through a sample insertion port, a valve that shuts off the sample insertion port when the probe is retracted, a switch for driving this valve, and a switch that operates when the probe is retracted. A direct sample introduction device comprising: a stopper that prevents insertion of a probe; and a lock mechanism that prevents operation of the stopper when the stopper is released and prevents the stopper from being released when the switch is closed. .

(2) The direct sample introduction device according to claim 1, wherein the stopper prevents movement of the probe or a rod provided parallel to the probe.

(3) Lock lever with a lock mechanism provided on the stopper
and a lock groove provided in the knob of the switch so as to engage with the lock lever when the stopper is pushed in. The direct sample introduction device according to claim 1 or 2, which is a registered utility model.

(4) The locking mechanism has a wire that advances through the sheath when the stopper is pressed, and a lock hole provided in one of the switches to engage with the wire. The direct sample introduction device according to any one of Item 3.
