A first power transmission bar fixed to the first rotation power generating unit, and a second power transmission bar bent from one end of the first power transmission bar in parallel with the feeding plate;
The driving shaft is fixed in a state of being coupled to the second power transmission bar of the power transmission bracket in a direction perpendicular to the lower surface of the feeding plate so that the vibration generator rotates in conjunction with the power transmission bracket, And a second rotating power generating unit for rotating the first rotating power generating unit at a predetermined angle. 8. The method of claim 7,
Wherein the first rotating body and the second rotating body are bearings, respectively. 8. The method of claim 7,
Wherein the first rotating power generating unit and the second rotating power generating unit are motors, respectively. 8. The method of claim 7,
Wherein the vibration generator is a solenoid or a piezo ceramic. 11. The method of claim 10,
Wherein the vibration generator including the solenoid includes a housing coupled to the second rotatable body, a pair of support posts disposed inside the housing in a direction parallel to the lower surface of the feeding plate, And a rotary plate coupled to the lower ends of the pair of support posts to receive the rotational force of the first rotary power generating unit.
