The present invention is the feeder device (3) which is equipped to a component mounting machine (1) and comprises: a reel bearing part (39) for bearing rotatably a supply reel (8) around which a carrier tape (81) has been wound; and a tape feeding mechanism (37) where the constitution includes a drive motor (36) allowing for intermittent drive, and where the carrier tape is pulled out by separation pitch from the supply reel and fed until reaching a component supply position (32). The feeder device (3) further comprises: a number-of-turns detection unit (calculation function of step S2) for detecting the remaining number of turns (Mr) for the carrier tape remaining on the supply reel; and a drive motor control unit (38) for controlling, according to the remaining number of turns, a drive current Id (IS, IM, IL) flowing in the drive motor. In this manner, the drive current is controlled appropriately according to a change in the torque required when the carrier tape is pulled out, and the waste of electrical energy is suppressed. |
