The above-described banknote handling apparatus is provided with a charging unit in which a plurality of banknotes are stacked on an upper side of a main body having a display unit and an operating unit for a user, and a discharging unit for discharging the counted banknotes are formed on the lower side, A plurality of rollers driven by the gears and the electric motor of the belt, and the bills stacked on the loading unit are conveyed one by one to the inside of the counter by the frictional force caused by the rotation of the rollers, and are finally transferred to the discharge unit.
Meanwhile, the bill processing apparatus has a function of detecting a tape attached to a banknote and sorting the banknote into damaged banknotes. In the conventional banknote processing apparatus, a thick roller that physically contacts the banknote is used, or a non-contact type (Ultrasonic Sensor) was used to detect the tape.
