the embodiments of the present invention will be described with reference to the accompanying drawings . in the drawings , the same elements are given the same numeral numbers even when the same elements are depicted in other drawings . in addition , the detailed known functions and constructions which are judged to be unclear for describing the subject matters of the present invention will be omitted . as shown in fig6 or 7 , the electronic locking apparatus according to the present invention includes an input apparatus provided outside a boundary frame 330 of a structure and an opening and closing apparatus provided inside the boundary frame 330 of the structure . as shown in fig6 the input apparatus and opening and closing apparatus are implemented by one central processing unit ( cpu ). in another embodiment , as shown in fig7 the cpu may be implemented by each controller . the latter case , a communication between the input apparatus and the opening and closing apparatus may be implemented by a wireless communication and may adapt a bidirectional wireless communication method such as an irda , rf , bluetooth , etc . the electronic locking apparatus and operation of the same according to the present invention will be described in detail with reference to the accompanying drawings . first , fig6 is a view illustrating the construction of an electronic locking apparatus and a wire communication method between an external input apparatus and an internal opening and closing apparatus according to a preferred embodiment of the present invention . the input apparatus 310 exposed to the outside of the electronic locking apparatus 300 includes a keypad 311 , a display unit 312 , a card input unit 313 and a power unit 314 . in addition , the opening and closing apparatus 320 installed in the interior of the electronic locking apparatus 300 includes a controller 321 , a power amplifier 322 and an opening and closing unit 323 for thereby forming an internal type controller of the electronic locking apparatus . in the electronic locking apparatus according to the present invention , the controller 321 is internally installed in such a manner that a signal system from an input apparatus to the controller is varied to a complicated signal system based on the password as seen in table 1 . as shown in fig6 in the electronic locking apparatus 300 according to a preferred embodiment of the present invention , when a user inputs a user &# 39 ; s password registered using the keypad 311 or inputs a card using the card input unit 313 , a digital clock signal corresponding to the password is applied to the controller installed in the interior of the system through a line c 01 . in this case , the line c 01 is formed of a plurality of lines , preferably , 7 ˜ 8 lines . the controller 321 verifies the inputted user &# 39 ; s password and transfers a result of the verification through the line c03 , and the display unit 312 displays the result of the same . if verified , a power is supplied to the power amplifier 322 through the line c04 . the power amplifier 322 performs a power amplification operation for thereby supplying a driving power to the opening and closing unit 323 through the line c05 for thereby driving the opening and closing unit 323 , so that the door of the safe is opened . at this time , the power supply is implemented in the panel of the external input apparatus for thereby commonly supplying the power to the input apparatus 310 and the opening and closing apparatus 320 . in addition , the input apparatus may be implemented by both the keypad 311 and the card input unit 313 or separately by the both . in the electronic locking apparatus according to a preferred embodiment of the present invention , since the controller is internally installed , a signal line system between the external input apparatus 310 and the internal opening and closing apparatus 320 is complicated and is varied based on the password , so that it is impossible to unlock the locking apparatus without using an authorized password . [ 0061 ] fig7 is a view illustrating the construction of an electronic locking apparatus and a wireless communication method between an external input apparatus and an internal opening and closing apparatus according to a preferred embodiment of the present invention . the input apparatus 410 installed outside the electronic locking apparatus includes a keypad 411 , a display unit 412 , a card input unit 413 , a first controller 414 , a transmission unit 415 , a receiving unit 416 , and a power unit 417 . the opening and closing apparatus installed inside the electronic locking apparatus includes a power unit 421 , a transmission unit 422 , a receiving unit 423 , a second controller 424 , a power amplifier 425 and an opening and closing unit 426 . as shown in fig7 in the electronic locking apparatus according to another preferred embodiment of the present invention , the controller is installed in each of the input apparatus 410 and the opening and closing unit 420 . namely , two controllers are driven . the first controller 414 installed in the input apparatus 410 converts a signal corresponding to the password inputted through the keypad 411 or the card input unit 413 into a wireless signal and transfers the wireless signal to the second controller 424 through the transmission unit 415 . a display control signal is received from the second controller 424 through the receiving unit 416 and is displayed on the display unit 412 . the second controller 424 installed in the opening and closing unit 420 verifies the password inputted from the first controller 414 through the receiving unit 423 and transfers a result of the verification to the first controller 414 through the transmission unit 422 for thereby displaying the signal and supplies the power to the power amplifier for thereby driving the opening and closing unit 426 , so that the door is opened . in addition , the power units 417 and 421 are installed in each of the input apparatus 410 and the opening and closing unit 420 , so that a driving power is supplied to a corresponding element , respectively . as shown in fig7 in the electronic locking apparatus , the signal transfer system between the input apparatus and the opening and closing apparatus is implemented based on a wireless communication , so that an excellent security is implemented with respect to the leakage of the password compared to the wire communication method . the electronic locking apparatus according to the present invention is widely adapted to the safes and various locking systems which need the locking apparatus and may be used as a locking apparatus of a boundary frame of a certain structure . in addition , as shown in fig7 when a certain card is used in the wireless communication system in the present invention , the user must carry a card reader and the card , so that the user feels inconvenience . in this case , as shown in fig7 the electronic locking apparatus in which the card input units 313 and 314 are omitted may be implemented . in the present invention , a communication transfer system between the inner and outer sides of the electronic locking apparatus is complicated and varied , so that it is possible to prevent an illegal unlocking operation ( illegal door opening ) of the electronic locking apparatus installed in a safe , entrance door , drawer , cabinet , etc . in addition , in the present invention , the electronic locking apparatus may be implemented as a more reliable locking apparatus . in addition , a signal transfer system between an external input apparatus and an internal opening and closing apparatus of the structure in which the electronic locking apparatus is adapted is changed differently from the conventional art , so that it is possible to prevent an illegal unlocking of the locking apparatus by providing a certain complexity and a certain variation to the signal transfer system based on the password like an inherent function of the electronic locking apparatus . in the present invention , the controller is installed in both the input apparatus and the opening and closing apparatus , and a bidirectional wireless communication is implemented between the same , so that it is possible to prevent any leakage of the password and an illegal unlocking of the locking apparatus . as the present invention may be embodied in several forms without departing from the spirit or essential characteristics thereof , it should also be understood that the above - described embodiments are not limited by any of the details of the foregoing description , unless otherwise specified , but rather should be construed broadly within its spirit and scope as defined in the appended claims , and therefore all changes and modifications that fall within the meets and bounds of the claims , or equivalences of such meets and bounds are therefore intended to be embraced by the appended claims .
