this invention relates to a display apparatus for movably displaying posters or the like. A pair of opposing annular rings (3) are respectively located to be driven to rotate at 2 RPM together in the direction of arrow C about a common axis. Opposing pairs of pin members (10) are slidably located in channels in each ring and carry a display panel (11) spanning between the rings around a defined annular path. A pair of rollers (6, 6'), driven at a faster speed in the direction of arrows A and B respectively, are located a minimal gap (30) apart on the defined path. A panel arriving at the rollers enters the gap and is swiftly urged between the rollers. It forms a loop and encounters a cowling (12) provided after the rollers which urges the looped portion to flop over towards the axis Y where it encounters a support cowling (13). Consequently, to a viewer looking through a first window (8), a panel is in view until it arrives at the roller and is swiftly removed from sight exposing the next panel in line before it too arrives at the rollers. To a viewer looking through a second window (9), a panel is in view until the panel that has just passed between the rollers suddenly flops down over the cowling under the action of gravity. |
