Further, in the above embodiment, when both ends of the longitudinal direction of the banknote run diagonally with respect to the transport direction during banknote transport, the skew angle O is detected by a well-known method, and the counted value of the counter,
For example, for IA, its correction value IA (θ) = it A CO3θ
By calculating (7) and comparing it with the reference value, it is possible to determine that the banknote is equivalent to a banknote without skew.

(Effects of the Invention) As explained above, according to the present invention, instead of determining whether the banknote is good or bad based only on dirt on the banknote based on reflected light or transmitted light from the banknote as in the past, The presence or absence of easily damaged parts is detected by the reflected light or transmitted light of the banknote, and it is determined whether the banknote is a good banknote or a damaged banknote. It is less susceptible to instability such as variations in the gap between the light receiving element and the banknote when moving relative to the banknote.
Defects in banknotes can be accurately detected, and generally, defects in external dimensions of banknotes are a major factor in determining whether banknotes are damaged during the circulation process, so the determination of damaged banknotes by detecting damage to banknotes according to the present invention will not result in erroneous determination. This method has advantages such as being able to perform stable and reliable determination of the integrity of banknotes without having to perform

[Claims] A banknote and a light receiving element that receives light transmitted through the banknote or light reflected by the banknote are relatively moved along a direction (width direction) perpendicular to the longitudinal direction of the banknote. In a bill fitness/damage discriminating device that discriminates whether a bill is a good bill or an unfit bill based on the output signal of the light receiving element, L/4, 2L/4, 3L/4 (however, L/4, 2L/4, 3L/4 from at least one longitudinal end of the bill is the length in the longitudinal direction of a standard banknote. means for calculating a value corresponding to the length in the width direction of the banknote from the period indicating the state in which the banknote is present in the conversion signal; and a reference value based on the calculated value and the length in the width direction of the standard banknote determined in advance. , and if all the calculated values are equal to the reference value within a predetermined tolerance range, the banknote is determined to be a valid banknote; otherwise, the banknote is determined to be an unfit banknote. Damage discrimination device.
