Abstract

A coin changer comprises a coin changer main part and an electronic type coin discrimination device which can be readily mounted to and detached from the coin changer main part. The electronic type coin discrimination device includes a detection coil for detecting characteristics of a deposited coin, a discrimination circuit for judging whether the deposited coin is a true coin or a counterfeit one in response to the output of the detection coil and produces a sole kind of discrimination signal representative of trueness or falsity of the coin regardless of the denomination of the coin, a true coin passage and a counterfeit coin passage provided behind the detection coil and a mechanical coin sort-out device provided in the true coin passage for sorting out coins by denomination. The coin changer main part comprises coin switches for detecting coins of respective denominations having been sorted out by the sort-out device, a coin receiving device for receiving the coins which have passed through the coin switches, a control circuit for effecting control operations including a money amount counting control, a vend control and a change payout control, and an electromagnetic device for distributing the deposited coin to either the true coin passage or the counterfeit coin passage in the coin discrimination device in response to the output of the discrimination circuit. This electromagnetic device distributes the coins by projecting or withdrawing a reject pin into or from a bifurcation of the true coin passage and the counterfeit coin passage.
