ABSTRACT:
A screw driving device includes a rotatable driver bit for driving a screw into a workpiece. A motor rotates the driver bit. A rotatable sprocket in engagement with a screw carrying belt feeds the screw carrying belt, and thereby feeds a screw on the screw carrying belt to a drivable place axially aligning with and being in front of the driver bit. A slide member supports the screw carrying belt. The slide member has a hole through which the screw is driven into the workpiece by the driver bit. When the screw is in the drivable place, a distance between the screw and an edge of the hole in a predetermined direction is greater than a distance between the screw and an edge of the hole in a direction different from the predetermined direction.
