1 is an exploded perspective view showing an international public personal mobile communication device according to the present invention, Figure 2 is a detailed block diagram showing an international public personal mobile communication device according to the present invention.

As shown in these figures, the international public personal portable communication device according to the present invention, in the personal portable communication device, comprising: a device body (11) for accommodating a plurality of building blocks for personal mobile communication; A key input unit 13 formed on the front of the device main body 11 for inputting a subscriber number to communicate with and a communication start command thereof for communication; An LCD 15 provided on the key input unit 13 and input through the key input unit 13 to visually display a response according to the input to a user; A receiving part 17 formed in a rectangular shape on the rear surface of the LCD 15 and the key input part 13; The accommodating unit 17 includes a slot 19 into which at least one of CDMA, AMPS, GSM, and TACS in which different wireless communication protocols are stored is inserted; The slot 19 is characterized in that the hierarchical control suitable for the corresponding communication method, the signal processing processor and the signal conversion, and the hierarchical control program are arranged to operate organically with each other. Here, the rear of the key input unit 13 is provided. A rechargeable battery 16 for supplying operating power is detachably installed in the rear panel. A rectangular accommodating portion 17 is formed on the rear surface of the LCD 15 and the key input portion 13, and the accommodating portion 17 is provided. ), At least one slot 19 of CDMA, Advence Mobil Phone System (AMPS), Groupe Special Mobil (GSM), and TACS is detachably accommodated.

In addition, the slot 19 is a unique number of each machine is set, the unique number is registered in the mobile communication base station of the country desired by the user is given a subscriber number. A plurality of conductive metals 21 are exposed so as to be electrically connected to a connection part (not shown) provided inside the 17. The conductive metals 21 are easily inserted into and detached from the receiving part 17 in the slots 19. A detachable induction part 23 slidingly coupled to the opposite side of the 21 is formed, and the detachable induction part 23 is formed with a locking part 24 to be fixedly coupled to the accommodation part 17. The slot At the coupling portion of the 19 and the detachable induction part 23, a guide groove 25 is formed toward the other side to prevent separation and separation in the insertion direction, and the guide groove 25 is formed at one side of the slot 19. Guide jaw 22 is formed to be inserted into the have.
