Claims

[Scope of utility model registration request]

(1) In an analysis apparatus equipped with an analysis combustion furnace consisting of a cylindrical body arranged substantially horizontally, and a sample boat feeding mechanism for sequentially feeding a plurality of sample boats to a position in front of the entrance of the combustion furnace, A movable rod whose tip is on the combustion furnace side, which is placed along the extension line of the combustion furnace immediately above the sample boat that has reached the entrance of the combustion furnace, and a rod portion that is retreated a predetermined distance from the tip of the rod. an introduction hook provided at the tip of the rod and directed downward at the first angular position of the rod so as to be able to engage with the outer surface of the rear end of the sample boat; a sloped side for riding on and over the rear end edge of the sample boat when the rod is directed downward at a second angular position displaced from the angular position of about 90° or more from the rear side; a retrieval hook having a series of vertical sides adapted to engage the inner surface of the trailing edge; A sample introduction stroke for pushing the rear end edge of the sample boat with a sample hook to introduce the boat into the furnace, leaving the boat immediately after introduction, and withdrawing to the starting position; It is advanced from the starting position to the first angular position, rotated to the second angular position at a position until the collection hook at the tip enters the furnace, and then further advanced to the same final position as the introduction stroke. By doing so, the recovery hook rides over the rear edge of the boat introduced into the furnace and engages with the inner surface of the boat, and when the boat is exited in this state and returned to the position in front of the entrance. comprising a rod support and drive mechanism for performing a sample retrieval stroke for returning the rod from the second angle to the first angle to release the boat and in this state back to the starting position; Features a sample boat introduction mechanism into the analytical combustion furnace.

(2) In the recovery stroke, move the rod. The axial position at which the rod is to be displaced from the first angular position to the second angular position is substantially the same as the axial position at which the rod is to be displaced from the second angular position to the first angular position. A mechanism according to claim (1) for utility model registration, characterized in that:
