The present invention relates to an apparatus for opening and closing a cover of an electronic blackboard, which has an improved structure capable of simultaneously using the electronic black board and a white board in a compact structure by, when the white board opened or closed at both left and right sides is opened, coming out at both outsides of a main frame to open or close a blackboard for writing. The apparatus for opening and closing a cover of an electronic blackboard according to the present invention comprises: a main frame including a blackboard for writing disposed at the front surface and guide rails formed at upper and lower sides thereof; a drive gear provided at the lower side of the main frame and rotated by rotary power of a driving motor; a driven gear disposed at the lower side of the main frame and disposed at a location spaced apart from the drive gear in a horizontal direction; a belt member for connecting the drive gear and the driven gear to transmit the rotary power of the drive gear to the driven gear; first and second coupling members integrally coupled with one side and the other side of the belt member to move with the belt member; first and second moving bars connected to the first and second coupling members, respectively, and moving in side directions at the time of the orbital rotation of the belt member to come out at both outsides of the main frame; and left and right covers connected to the first and second bars via support brackets to move with the first and second moving bars, respectively, disposed outside the blackboard for writing, and disposed to be able to come out at both outsides of the main frame (100). |
