摘要

The publicity panel carries discs which turn in front of a window parallel to them. There is a stack of disc plates (2) mounted on a support plate (10) and turning around the same axis and a plate (1) which can conceal the others. The plates are offset relative to the information indicia (9) which they carry. The stacks of plates can be placed side by side and those in the same stack turn around a pivot carried by the concealing plate.
