Now, when a paper sheet to be inspected, for example, a banknote, is inserted from the receiving opening 9, a detection signal from the first optical detection sensor (IOA, IIA) on the entrance side is sent to a control unit (not shown). As a result, the motor 2 is driven, and the banknote is taken into the identification device 100 by the conveying device. However, when the banknote passes over the net 21, there is no possibility that the banknote will stick to the back side of the banknote, that is, the side that contacts the presser roller 13. Of the magnetic particles, dust collection chamber 2
Magnetic powder in an area corresponding to the width direction of 3 is attracted by the magnetic force of the permanent magnet 25, and is transferred to the lower dust collection chamber 2 through the lA21.
It is collected in 3.

However, since the width of the dust collection chamber 23, that is, the width in the direction perpendicular to the conveying direction, is wider than the width of the presser roller 13, the magnetic particles on the back side of the banknote at least in the area in contact with the presser roller 13 are removed. This prevents magnetic particles from adhering to the presser roller 13, thereby making it possible to eliminate erroneous identification by the magnetic sensor 12.

When the leading edge of the banknote is detected by the optical detection sensor 26, the presence or absence of an output from the magnetic sensor 12 at that time is monitored, and the control unit starts determining whether the banknote is genuine or not. If it is determined that the banknote is not suitable as a genuine banknote, the control unit causes the motor 2 to rotate in the reverse direction to return the banknote to the receiving slot 9. If it is determined that the banknote is appropriate as a genuine banknote, the conveyance continues, and when the passage of the trailing edge of the banknote is detected by the second optical detection means 10B and IIB, the control unit outputs a genuine banknote signal and Trigger a timer for the time until the banknote is sent out of the identification device 100,
After a predetermined time has elapsed, the motor 2 is stopped.

In the above description, the permanent magnet 25 held by the holder 24 and the tumor collection chamber 23 are provided only on the same side as the presser roller 13, but although not shown, , and a permanent 6F1 stone, a dust collection chamber, a screen, and a holder with the same structure are provided so as to be shifted to the upper and lower positions on the side of the receiving port 9 from the magnetic sensor 12 and presser roller 13, and paper sheets are removed. It can also be configured to collect magnetic particles from both sides.

(Effects of the Invention) As described above, according to the present invention, an opening wider than the scanning width of the magnetic sensor is provided on the opposite side of the magnetic sensor between the paper sheet receiving opening and the magnetic sensor in the conveyance path. Since we have installed a dust collection chamber and a 6n stone that can attract magnetic particles attached to paper sheets in the dust collection chamber, it is possible to imitate 6I1 powder that has adhered to the presser roller from paper sheets in the form of a transfer. It is possible to prevent the normal detection function of the sensor from being impaired, and it is possible to continue stable identification over a long period of time even in environments where there are many powder dishes containing magnetic particles, such as machine factories and amusement parks. It has become possible to significantly improve environmental resistance.
