ABSTRACT:
The present invention is related to a discharging device for a head drum, and more particularly to a discharging device, wherein the static electricity which occurred from the head drum is effectively discharged using the discharge device. A fixed end of a bracket is fixed on a main chassis by a screw, and a free end forms a bracket protrusion. A coil spring is put on the free end of the bracket. A first end of a leaf spring is put inside the coil spring together with the free end of the bracket, and the first end forms a leaf spring protrusion. A tip is installed between a second end of the leaf spring and the head drum. Static electricity transmitted to the tip is transmitted to the bracket via the leaf spring. Then, static electricity is discharged through the main chassis. Thus, this discharging device can improve productivity since extra riveting or bonding is unnecessary. Also, the grounding property of the head drum is improved because the close adhesion between the tip and the revolving shaft is ensured by the coil spring.
