PROBLEM TO BE SOLVED: To provide a combined metering device capable of avoiding occurrence of malfunction and the like by preventing dislocation of a rotating shaft behind a speed modulating mechanism, even if the speed ratio contains fraction in the speed modulating mechanism converting rotation speed of a rotary drive source to a predetermined rotation speed. SOLUTION: In the metering device 10 that implements processes of metering, stocking, and discharging, while driving continuously rotation of a metering section 13, stocking section 14, and a discharging section 15 and the like, a servomotor M1 providing rotary driving force rotates continuously in the one direction and meanwhile, a reduction gear 55 is attached to the servomotor M1. The metering device 10 is equipped with a positioning control section 50 controlling rotation of rotating shafts A1 to A3 behind the reduction gear 55, by controlling the rotating speed of the servomotor M1 and a correcting section 51 correcting dislocation between a location recognized from controlling of rotating shaft A1 to A3 and an actual location. The correcting section 51 corrects dislocation (pulse-number) equivalent to fractional part of the deceleration ratio of reduction gear 55 at every predetermined rotating number.
