A digital door-lock device is provided. Given in the practice example of the present invention, the digital door-lock device includes a pair of door-lock main bodies to which a lever is combined in a rotatable manner and which are installed inside and outside a door, respectively; and a rotational connection module which is installed at the main bodies to deliver the rotational force of the lever to a door latch module, while being connected to the lever. The door-lock main bodies are installed between the lever and the rotational connection module and includes a rotational housing which has a left-handed lever section for delivering the clockwise rotational force of the lever to the rotational connection lever and a right-handed lever section for delivering the counterclockwise rotational force of the lever to the rotational connection module; and a section moving unit which is installed on one side of the rotational housing in a movable manner toward either the left-handed lever section or the right-handed lever section and moves from either the left-handed lever section or the right-handed lever section. |
