The battery cell 130 supplies power for driving the components of the mobile communication terminal 10 and the battery pack 100. The RF-INLAY antenna 150 is disposed inside or outside the battery pack 100 and outputs a signal received from a non-contact SIM type smart card electrically connected through the SIM type connector 122, Input a signal to SIM type smart card. The ID-1 type connector 142 is connected to the smart card reader 122 and reads information from a smart card chip (hereinafter referred to as an ID-1 type smart card) Type smart card 30, a plurality of contact terminals corresponding to the respective contacts of the ID-1 type smart card 30 are provided. Here, the ID-1 type smart card 30 is attached to and detached from the battery pack 100 in a sliding manner. The SIM type connector 122 is connected to the smart card reader 122 and the RF antenna 150 and is connected to a SIM type smart card 20). Here, two contact terminals out of the plurality of contact terminals are electrically coupled to the L1 and L2 contacts of the RF antenna 150 and the SIM type smart card 20, respectively. Thus, the SIM type smart card 20 can perform RF communication with an external device. The remaining contact terminals, which are not coupled to the RF antenna 150, are coupled to the smart card reader 126. The smart card reader 126 is also coupled to the ID-1 type connector 142 and the SIM type connector 122 and reads or moves information from the smart cards 20 and 30 inserted in the respective connectors 126 and 142 And performs an operation of recording information received from the communication terminal (10). The smart card reader 126 transmits the information read from the smart cards 20 and 30 to the mobile communication terminal through the connection terminal 124. [ Also, the smart card reader 126 is coupled to the battery pack control terminal 124d. The control signal received from the mobile communication terminal 10 through the terminal allows the smart card reader to operate in the power down mode power down mode, or vice versa. Therefore, if the smart card is not used, the service life of the battery can be extended by turning off the power of the smart card reader. In addition, the battery protection circuit 128 performs an operation of preventing an overcurrent generated instantaneously in the battery cell 130 to prevent a failure of the battery cell. The connection terminal 124 is connected to the smart card reader 126 and the battery protection circuit 128 and supplies power to the mobile communication terminal 10 and communication between the smart card reader 126 and the mobile communication terminal 10.
