PURPOSE:To obviate spilling down, etc. of samples and to prevent wasteful spending of time for cooling sample-receiving trays by burning and decomposing the sample then returning the sample-receiving part at the tip of an introducing bar to the original boat receiving position and returning slidably the same as it is to the relay position on a conveying path. CONSTITUTION:A cross feed conveyor 4 is disposed in the position in proximity and parallel to and with the left side wall 1a in a frame 1 and a longitudinal feed conveyor 5 is disposed at one end thereof. These two conveyors 4 and 5 constitute a series of sample boat feed mechanisms. The conveyor 5 supports further parallel the trays 6 which support parllel sample boats so as to parallel the same with the axis of a furnace 3. The conveyor 4 receives the trays 6 fed by the conveyor 5 and moves the same in the direction intersecting with the furnace axis. The conveyance plane of the conveyor 4 is positioned at the level higher than the extension line of the furnace 3 and the position right above said extension line is a relay position A. |
