Blackboard with one or more boards (3 - 8) which can be slid respectively in a tower, horizontal guide rail (2) and which are safeguarded against tilting out of their vertical position by means of an upper guide rail (1), whereby the upper guide rail (1) clasps the board (3 - 8) upwards with such a free travel in vertical direction, that it is possible to lift the board (3 - 8) out of the lower guide rail (2) and to once again use it with its back to the front, and whereby the upper and lower guide rails (1, 1', 1'' ; 2, 2', 2'') are arranged parallel in pairs behind each other if several boards are arranged, characterized in that between the upper and lower guide rail (1, 2) behind the plane of these guide rails (1, 2) or, if several guide rails (1, 1', 1'' ; 2, 2', 2'') are arranged parallel in pairs behind each other, behind the plane of the rearmost guide rails (1, 2) a projection screen (9) is supported so that it can be tilted on its lower edge, pre-stressed to the front above the support by means of a spring (23) and held in a fixed position by means of an adjustable cable (24) which pulls the projection screen (9) backwards above the support.
