ABSTRACT:
For sorting input coins by use of their paramagnetic properties, such as a paramagnetic coin, a ferromagnetic coin, and nonmagnetic coin, a device comprises an attracting magnet for attracting the ferromagetic coin by an attracting force of magnetic flux density between 700 and 800 gauss and to allow passage of the paramagnetic coin and the nonmagnetic coin. An incliend rail rolls coins to make coins fly out from a outlet end. A guide magets is disposed on the outlet end and guides the paramagentic coin but the nonmaganetic coin to a under side of the outlet end by attractive force of magnetic flux density between 4000 and 5000 gauss.
