PROBLEM TO BE SOLVED: To provide a combinational metering device capable of suppressing damages of an article, and moreover, of suppressing deviations in supply to metering hoppers. SOLUTION: The combinational metering device 1 is equipped with a throwing chute 10 for dropping downwardly the article M supplied from above; a dispersion part 2 for dispersing around the dropped article M; and a plurality of metering hoppers 6i arranged substantially on a circumference and combines measurement values obtained by metering with the metering hoppers 6i. The throwing chute 10 has a discharge outlet section 30 of an inverted conical shape and the discharge outlet 30 is made of three or more flat plate-like elastic sheet members 32 made into a substantially triangular shape. Mutually adjoining oblique sides of the individual substantially triangular elastic members 32 are brought into contact with or approach each other, with each elastic member 32 curves substantially uniformly due to the weight of the article M inside the discharge outlet 30; and by having the discharge outlet 30 open the article M is made to drop downward.
