PURPOSE:To easily open and close a cover of an arbitrary selected specimen vessel. CONSTITUTION:The specimen injection end of a capillary 2 is fixed on an injection block 6 and, with a specimen vessel 26 pushed up on the lower face of the injection block 6, the specimen injection end of the capillary 2 is immersed in a specimen. The specimen vessel 26 is arranged on a turn table 24 and a cover 32 of a shape adhering to the opening part of the specimen vessel 26 is set every specimen vessel. The supporting point of an arm 34 of the cover 32 is rotatably supported on the end face of the circumference of the turn table 24 and the arm 34 is formed of a bent shoulder part 34a and a bar 34b projected outward of the turn table 24. When the turn table 24 is lifted, with the bar 34b made to but on a baffleplate 38 the cover 32 is opened and, when the turn table 24 is lowered, with the shoulder part 34a is made to abut on the baffleplate 38 the cover 32 is closed. |
