The present invention discloses an electronic door lock device opened only when an opening button, placed inside a front door, is manipulated in a set direction. The electronic door lock device includes: a first input part installed inside a front entrance door and placed to enable a user to unlock the front entrance door to accept first normal unlock input and first error input; a control part generating a signal to unlock a locked state of the front entrance door in the event of the first normal unlock input; an operating part making the locked state of the front entrance door unlocked when the control part generates and delivers the signal to unlock the locked state of the front entrance door; and a housing part formed to surround the control part and the operating part to protect the control part and the operating part. Therefore, the electronic door lock device is opened only when the opening button is touched and manipulated in a specific button without manipulating the opening button by simply pressing the opening button. Moreover, the present invention is capable of completely preventing the opening button from being forcibly manipulated by the outside, thereby improving the security and reliability of the electronic door lock device. |
