Open the CIPO recordAbstract From the Canadian patent
An electro-mechanical coin totalizer for newspaper vending machines and the like includes a coin chute having an arcuate shoulder a wake-up arm, and optical sensors for measuring a chord length on coins inserted in the totalizer. A coin inserted in the coin chute travels along the arcuate shoulder, whereby coin bounce is minimized and the accuracy of coin chord measurements is enhanced. The wake-up arm biases coins against the arcuate shoulder and reduces coin bounce in direct proportion to the size of the coin.

Why it's free to use
- Filed October 29, 1993. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended October 29, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 29, 2015.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
