Open the CIPO recordAbstract From the Canadian patent
A coin mechanism includes a coin conveyor provided with a hub on its front face, which rotates in a recess formed in the rear face of the cover plate. The hub reinforces the structural integrity of the coin conveyor allowing the, mechanism to accommodate large coins without diminishing the reliability of the rotational locking mechanism. Preferably the recess is dimensioned as a bearing for the frontal hub, which secures the coin conveyor against shifting due to wearing of parts so that the mechanism retains a high tolerance for measuring the diameter of the coin over a longer period of time.

Why it's free to use
- Filed September 18, 1997 and granted April 23, 2002. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended September 18, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 18, 2019.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
