<Effect>
When the banknote identification device 1 is equipped with the magnetic sensor 49 that reads the magnetic information of the banknote, it is necessary to arrange the pressing member 50 having the pressing portion 51 that presses the banknote against the magnetic sensor to ensure the magnetic output. In this embodiment, since the recess 55 for receiving the rotating shaft 24 of the downstream roller 23a is provided on the back side of the pressing portion 51, that is, the side not facing the magnetic sensor 49, the pressing portion 51 and the downstream roller 23a are provided. It can arrange | position on the same axis | shaft.
Accordingly, since the transport roller (downstream roller 23a) and the lower transport belt 21 can be disposed in the lateral transport position 11a of the bill transport path 11 and in the lateral direction of the magnetic sensor 49, the magnetic sensor 49 portion. A conveyance force can be given to the bill which is running. As a result, even if the banknote has no waist, the magnetic sensor portion can be conveyed without generating banknote jam.

The pressure member is a pressure roller that is driven to rotate (for example, the pressure rollers 21a and 21b configured by elastic members of Japanese Utility Model Laid-Open No. 3-07401), and the rotation shaft of the pressure roller that is driven and rotated is the drive shaft of the downstream roller 23a. 24 (for example, the pressing roller 22, the conveying rollers 23a to 23c, and the roller shaft 21 of Japanese Utility Model Laid-Open No. 62-146271) can be considered. However, as described above, since the magnetic sensor 49 is a sensor that detects the movement of magnetism, the pressing roller is driven and rotated with magnetic dust or the like attached thereto, and the bill passes through the magnetic sensor 49 portion. If not, the dust adhering to the pressing roller moves on the magnetic sensor, causing a problem that the magnetic sensor detects magnetism even though the bill is not conveyed.
In addition, since each pressing roller is arranged on the same axis, it becomes impossible to apply an appropriate pressing force to the corresponding magnetic sensor, resulting in variations in the output of the magnetic sensor, which is the worst case. Cannot obtain the magnetic output necessary for identifying the banknote.
Therefore, a pressing roller having the drive shaft 24 as a rotation shaft cannot be used as a pressing member.

In the present embodiment, the pressing surface 53 of the pressing member 50 does not have a portion that moves in the banknote transport direction. Therefore, even if magnetized dust adheres to the pressing surface 53, the magnetic sensor 49 portion is inserted into the banknote. The magnetic sensor 49 does not detect a magnetic output that is unrelated to the banknotes when the currency has not passed.
Furthermore, in the present embodiment, the auxiliary roller 80 that forms the curved portion 12 is disposed in the movable unit 40 in the lower conveyance belt 21 portion located immediately upstream in the bill conveyance direction of the downstream roller 23a. A conveying force can be additionally applied to the banknote immediately upstream.
In the present embodiment, the pressing portion 51 is supported so as to move up and down (swing) around a shaft support portion 65 formed at the distal end portion of an arm 63 extending from the pressing portion 51 along the upstream side in the bill conveyance direction. Yes. For this reason, the pressing surface 53 of the pressing part 51 can press a banknote correctly with respect to the detection part 49a of the magnetic sensor 49. FIG. Accordingly, it is possible to accurately identify the banknote without causing unnecessary fluctuation in the magnetic output.
