ABSTRACT:
An electronic blackboard apparatus, which reads a writing on a writing sheet fitted on a blackboard framework and which electronically copies the writing onto a recording medium. The apparatus includes a blackboard framework foldable together with the writing sheet, and a stand supporting the blackboard framework and a copying device. The stand is reducible in size while supporting the blackboard framework and the writing sheet in their folded position and the copying device. The length of the stand is reducible after the blackboard framework and the writing sheet have been folded to reduce their lengths. The blackboard framework and the writing sheet which have been folded are overturned into a space between opposite legs of the stand and the legs are then closed.
