Coin denomination distinguishing method and apparatus

摘要

A coin denomination distinguishing apparatus that can initialize reference denominations, comprising: a circuit board on which there is installed an arched conductive strip and plurality of contact segments concentric with the conductive strip; the contact segments are queued in different serial numbers, define the first contact segment as a start point, divide the rest into several groups and connect the contact segments with each other of the same group; a sweep concentric with the conductive strip that can glide along an imaginary arched path and can contact the conductive strip and one of plurality of contact segments; the apparatus can select the corresponding measurement of the maximum serial number when the sweep contacts plurality of contact segments and initialize a reference denomination with the initializing and choice unit when first use.
