The present invention provides a standing type multi-surface blackboard. The present invention provides the standing type multi-surface blackboard, which can be lifted and lowered with minimum force in lifting and lowering a writing board to a height adequate to a writing action, simplifies a lifting and lowering structure to reduce manufacturing costs and to be easily used, and ensures a writing and displaying area equivalent to that needed when four boards are used by using one standing type multi-surface blackboard in a limited narrow area. Therefore, space usability of a lecture room can be largely enhanced. To this end, the present invention provides the standing type multi-surface blackboard, which has a conventional stand having rotatable castors at a lower side, and a guide frame in the front and the rear of the stand, and has a bracket for coupling a slider, capable of being lifted and lowered within the guide frame, and boards, thereby having one board at each of the front side and the rear side to lift and lower the boards alternately. |
