Claims

[Scope of Claim for Utility Model Registration] 1. In a sample suction device in which a sample container sealed by a stopper is held and a thin tube moves to pierce the stopper to aspirate the sample inside the sample container, the stopper of a fixed sample container is A cover that can be opened and closed can cover the area where the tip of the thin tube for piercing moves while being exposed, a detection means that detects whether the cover is open or closed, and a movable part that comes into contact with the cover during sample aspiration. A sample suction device equipped with a safety mechanism characterized by having a lock mechanism that prevents the cover from being opened. 2. The sample suction device with a safety mechanism according to claim 1, wherein the sample container is held on the back side of the cover. 3. A sample suction device equipped with a safety mechanism according to claim 1 or 2, wherein the detection means is a switch that is pressed by the cover when the cover is closed, and this switch is used as a starting switch for the sample suction device. 4. The lock mechanism has a movable part connected to a drive source, and when the cover is closed, this movable part does not come into contact even if the capillary moves forward, and when the cover is open, even if the capillary tries to move forward, the movable part does not come into contact with it. 4. A sample suction device equipped with a safety mechanism according to claim 1, comprising a protrusion provided on the cover, with which the movable portion abuts.
