摘要

Device permits, by a simple manoeuvre, the display on a plaque of the selling price and year of manufacture or some other information relating to a vehicle, or other item. The figures displayed can be modified at will and the device may be used again and again. At the back of the plaque is an arrangement of differing diameter concentric discs each carrying numbers around their periphery. These discs can be rotated about their axis. a certain movement of the discs will produce a certain combination of numbers in a window in the device, the maximum limit depending upon the number of discs. The larger diameter discs have a circular slot cut in them through which one can see the figures on the smaller diameter discs. The figures on all the discs have the same dimensions and the same spacing.
