PURPOSE:To obtain a normal ticket/loss ticket discriminating device, etc., having high probability at a low cost by fetching a difference of strength of stiffness of paper sheet, etc., as a variation of the rotational quantity, detecting a variation of its rotational quantity and discriminating a nature of the paper sheet, etc. CONSTITUTION:When paper sheet, etc., which are carried come into contact with a detection rotating body 33, a torque corresponding to pressing force generated in accordance with strength of stiffness of the paper sheet, etc., which is generated due to its contact is given to the detection rotating body 33, and also, a rotational resistance is given to the detection rotating body 33 by a rotational resistance giving means 39, and when the torque is below a prescribed value, the detection rotating body 33 is held in a fixed stop state or in a rotating state for rotating at a different peripheral velocity from a carrying speed of the paper sheet, etc., and when the torque is above the prescribed value, a variation of the rotational quantity is generated in the detection rotating body 33 in accordance with the torque. Subsequently, a variation of rotational quantity is detected by a rotational quantity detecting means 38. |
