A stiffness detector (10) transmits acoustic waves to a paper sheet (7) at a predetermined angle to excite Lamb waves. The stiffness detector receives leaky waves of the Lamb waves propagated through the paper sheet at different angles with respect to the paper sheet by a plurality of reception sensors (2). The stiffness detector is configured to specify a maximum leak angle at which a leak amount of the acoustic waves from the paper sheet becomes maximum based on outputs from the plurality of reception sensors in the reception module and to judge a degree of fatigue of the paper sheet based on the specified maximum leak angle.

摘要:
The invention provides a neutralization apparatus which simplifies an apparatus composition, lowers an apparatus cost and removes electrical charge effectively from a ribbon-like substance which is charged by stripping, and provides a printer (10) having the neutralization apparatus. The neutralization apparatus neutralizes an ink ribbon (12). The neutralization apparatus has a conductive roller (34) which is arranged so as to contact the surface of the ink ribbon (14) and a neutralization brush (32) which counters the back of the ink ribbon (14). A balance of the electrical charge of the surface and the electrical charge of the back of the ink ribbon (14) is broken by electrical discharge caused by the conductive roller (34). And thereby, the charged voltage of the electrical charge of the back of the ink ribbon becomes large and the neutralization brush remove the electrical charge charged to the back of the ink ribbon (14) effectively.

摘要:
A stiffness detector (10) includes a bending portion (4) configured to bend a paper sheet (7) 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.
