入射する。(Prior Art) Conventionally, one way of determining whether a sheet of paper (for example, securities such as banknotes) is appropriate or not is based on whether or not the sheet is completely dirty. As the detection means, a method as shown in FIG. 2 is adopted. In other words, the paper sheet (P) is transported in the direction of the arrow by a belt (not shown), etc., and the entire dimension of the paper sheet (P) in the direction perpendicular to the transport direction is measured through a light source (a lens that emits light from ■). The reflected light is imaged on the slit plate (0) through the condensing lens (2).The light that passes through the slit plate (0) is diffused by the diffusion node (2) and enters the photoconductor (2). On the other hand, the light transmitted through the paper sheet (P) is diffused by the diffusion node (9) and enters the photoelectric element (1o).

A command signal is sent from the circuit (15) to the integrators (13) and (14) to integrate over the entire length of M and the stool (P) in the transport direction.The integrators (13) and (14) The output integrated by

。However, when using this method to determine whether the paper sheet (P) is suitable or not using transmitted light, if the paper sheet (P) is the same thickness, the amount of light transmitted is smaller when the paper sheet (P) is stained. However, there is considerable variation in the thickness of paper sheets, and when the paper sheet is thick, the amount of permeation decreases, and there is a risk that the sheet may be erroneously determined as an inappropriate sheet. In addition, when determining whether the paper sheet (P) is appropriate or inappropriate based on reflected light, the amount of reflected light from the entire paper sheet (P) may be smaller than expected because the density of ink printed on new paper sheets (P) is higher. This method has drawbacks such as the possibility of misclassifying new paper sheets as slightly soiled paper sheets.

のと。(Function) In other words, the present invention has the above-mentioned configuration, so that even if the paper sheet is proper but is misjudged as inappropriate because of its thick thickness or because there is little transmitted light, the paper sheet can be processed. Because there is a lot of reflected light from the surface of the paper leaf i, it is not determined to be inappropriate, and even though there is little reflected light due to the high density printed on the paper leaf i, there is a lot of transmitted light, so it is incorrectly determined to be inappropriate. There is no '. Therefore, paper sheets that are generally slightly soiled are considered appropriate.
不適正なものとに高精度で判別することができる。It is possible to determine with high accuracy whether the image is inappropriate or not.
