With a banknote processing apparatus, banknotes stored in a storing section are fed in a feeding direction one by one by take-in rollers. First and second sensors for detecting passage of the banknote are arranged in a direction perpendicular to the feeding direction of the sheets and spaced from each other. A difference between a first passing timing at which a leading edge of the banknote is detected by the first sensor and a second passing timing at which the leading edge of the banknote is detected by the second sensor is detected by a control section. A second difference between a passing timing at which a trailing edge of the banknote is detected by the first sensor and a passing timing at which the trailing edge of the banknote is detected by the second sensor is detected by the control section. If the first and second difference are different from each other, it is determined by the control section that a bent or torn portion exists in the banknote.
