A bank note counting apparatus detecting whether there exists magnetic ink is provided to maximize magnetization of magnetic ink of the bank note while minimizing a noise occurring at a magnetic sensor. A bank note counting apparatus includes a bank note transfer roller unit, a sensor unit and a controller(300). The bank note transfer roller unit is composed of a supply roller, a feeding roller and a take-out roller. The supply roller supplies bank notes, supplied from a bank note input opening, for the feeding roller one by one. The feeding roller feeds the bank note. The take-out roller takes out the bank note supplied by the supply roller and the feeding roller. The sensor unit includes a magnetic unit and magnetic sensors. The magnetic unit magnetizes magnetic ink printed on the bank note which has passed through the bank note input opening. The magnetic sensors senses the bank note magnetized by the magnetic unit. The magnetic unit includes magnets which are divided into plural ones and then adhered to one another. The controller makes a bank note side magnet discharge a stronger magnetic force and a magnetic sensor side magnet discharge a weaker magnetic force such that the magnetization of the magnetic ink is maximized while the noise at the magnetic sensor is being minimized. A first color sensor(220) is installed at a guide plate to sense color information on one side of the bank note. |
