PROBLEM TO BE SOLVED: To prevent partial rise of a nozzle chip and efficiently perform waste recollection by disposing a thin-line shaped obstacle colliding with a dropping nozzle chip and scattering it in the vertical downward direction of a discarding position. SOLUTION: An obstacle is formed of a thin-line material having anti- corrosion property, for example stainless wire of approx. 1mm in wire diameter, bent in the substantially U-letter shape, and fixed to a frame 14 or the like provided with a remover 108. At this time, an intermediate side 12a of the obstacle is disposed so as to cross a drop axial line of a nozzle chip 100. A nozzle base portion 102 at which specified analysis operation is completed moves to a discarding position 104 of the chip 100 and removes the chip 100 by hooking an upper end portion thereof on the remover 108. The removed chip 100 drops and collides with the obstacle, and scatters to the left and right. The obstacles are never coupled with each other because they are rotated due to collision, and even if specimen or reagent adhered to the chip 100 scatter, these are never adhered to the obstacle because of its thin line shape. |
