Abstract
A new stamp-vending machine designed and developed for the British Post Office is described. A brief outline of stamp machine history is followed by a review of the reasons for the adoption of the particular design. A description of the mechanism shows how the design specification has been met, despite the limitation of size imposed by existing mountings. The stamps are issued from a roll by the user operating a lift flap after insertion of a valid coin, and no additional source of power is required. The machine may be readily set to issue any predetermined stamp combination.
