1. A dispenser for dispensing substantially non-compressible solid objects one at a time comprising:

  • a receptacle having a substantially hollow interior for storing a plurality of objects to be dispensed, said receptacle having an opening through a first wall thereof;

    a passageway extending from said opening to the exterior of said dispenser;

    a pair of cooperating structures disposed in said passageway, at least one of said cooperating structures moveable relative to the other cooperating structure whereby movement of said moveable structure carries said objects through said passageway and between said structures substantially one at a time;

    said at least one movable structure at least partially formed from a compressible material, said compressible material having dimensions sufficiently larger than dimensions of one of said objects such that a discrete indentation is formed in said compressible material by said object, said indentation possessing a surface disposed behind said object relative to the direction of movement of said object through said passageway thereby facilitating movement of said object through said passageway;

    moving means for moving said movable structure; and

    detecting means for detecting the passage of each said object past a predefined point in said passageway.
