A keypad having an electrostatic discharge structure for an automated teller machine is provided to prevent an error due to static electricity by increasing resistance of a PCB(Printed Circuit Board) for remaining static electricity through a solder mask formed on the PCB. A front panel unit(110) includes a plurality of key buttons. A keypad PCB(130) is coupled to a rear surface of the front panel unit and generates a signal by contact through drive of the key buttons. A pair of conductive gaskets(140) are coupled to the keypad PCB. An inner bracket(150) is coupled to the keypad PCB through a screw connection unit. An operation PCB(160) is connected to the inner bracket and performs an operation by receiving the signal generated from the keypad PCB. An outer bracket(170) is coupled to the operation PCB. A pair of conductive copper plates includes bodies. One sides of the bodies are connected to the front panel unit and the other sides thereof are connected to the outer bracket to surround an outer part of a structure formed by stacking the front panel unit to the outer bracket. |
