摘要：
A stiffness detector includes a bending portion configured to bend a paper sheet to be carried. The stiffness detector transmits acoustic waves to an incidence point on an inner surface of the paper sheet which is bent by the bending portion and is carried, thereby exciting Lamb waves. The stiffness detector receives leaky waves of the Lamb waves emitted from a detection point on the inner surface of the paper sheet. The stiffness detector specifies a maximum crest value based on the received signals, and judges whether the paper sheet is an unimpaired sheet based on the specified maximum crest value.
