FIELD: equipment for demonstrating illustrative material, may be used in educational, advertising and other enterprises. SUBSTANCE: multiplotting table has a number of plotting tables connected one with another and provided with sides and transparent drawing rods for retaining illustrative material on plotting table surface. Plotting tables are rigidly interconnected by means of slots and retainers and are secured by retainers for sliding to sectional horizontal bar. Multiplotting table is further provided with attachment for connecting horizontal bar to vertical bar, device for attaching plotting table with its lower part to any horizontal support, and suspender fixed on sectional bar for attaching plotting table with its upper part to any horizontal support. Large sized illustrative material may be attached to plotting tables by means of pins and small sized illustrative material may be attached by magnetic members. In such case, plotting tables may be made of magnetic material. Method involves inserting sheets of illustrative material of first exposition between surfaces of plotting tables, their sides and drawing rods; inserting sheets of second and subsequent expositions between plotting table surfaces and sheets of previous exposition; demonstrating first and subsequent expositions in succession, with sheets of previous expositions being removed in succession; changing sheets of separate fragments depending on demonstration purposes; applying transparent material onto sheet surface with exposition fragment and making marking on transparent material to improve informational capacity of plotting table. EFFECT: increased efficiency by convenient demonstration of illustrative material, provision for easy and quick mounting and dismantling of illustrative material and equipment, and simplified construction. 3 cl, 4 dwg
