Abstract: A control device of the tape feeder includes: a step-out detecting section for detecting a step-out of a stepping motor; a memory section for storing a target angle of a sprocket for positioning one of multiple cavities at a supply section; and a restoration process section for performing origin alignment, when the step-out detecting section detects a step-out of the stepping motor, wherein pulse power is supplied to the stepping motor so that the sprocket reaches a predetermined angle, supplying the pulse power to the stepping motor in accordance with the current angle and the target angle of the sprocket after the origin alignment is completed, and moving one of the multiple cavities to the supply section.

Abstract: A tape feeder including: an angle sensor configured to detect a final angle of the sprocket at a point in time at which interruption of power supply to the tape feeder is detected, and a current angle of the sprocket at a point in time at which resumption of power supply to the tape feeder is detected; and a control device configured to, when resumption of power supply to the tape feeder is detected, set a target angle of the sprocket based on the final angle, and perform control to rotate the sprocket from the current angle to the target angle so as to convey the carrier tape to a predetermined position.
