[1-3. Configuration of the identification section]
As shown in FIG. 3, the discrimination unit 18 controls the control unit 12 while running the bills forward or backward along a substantially horizontal conveyance path 32 in the rectangular parallelepiped discrimination unit housing 30. Based on this, the bills are identified. Incidentally, for convenience of explanation, FIG. 3 schematically shows each internal component by omitting the left side plate of the discrimination unit housing 30 and the like.

  The conveyance path 32 includes an upper conveyance guide 34U and a lower conveyance guide 34D, drive rollers 38, 40 and 42, driven rollers 44, 46 and 48, a reference roller 56, a thickness detection roller 58, and a magnetic gap roller 54. It is comprised by. The drive rollers 38, 40, and 42 and the magnetic gap roller 54 are made of rubber-based elastic members, and have a high frictional force against bills. The driven rollers 44, 46 and 48 and the thickness detection roller 58 are made of metal, resin, rubber-based elastic member, or a combination thereof. The reference roller 56 is made of a predetermined metal material. The upper transport guide 34U and the lower transport guide 34D each have a planar upper transport surface 34AU and a lower transport surface 34AD that face the paper surface of the bill BL, and a bill transport path between the respective transport surfaces. 32 is formed.

  In the discrimination unit 18, modules such as a magnetic detection unit 50, a banknote image detection unit 53, and a thickness detection unit 60 are sequentially arranged so as to go from the rear side to the front side in the discrimination unit housing 30.

  In the lower conveyance guide 34D, the driving rollers 38, 40 and 42, the reference roller 56, and the magnetic gap roller 54 are rotatable so that the central axis is directed in the left-right direction, that is, in the direction perpendicular to the conveyance direction of the bills BL.

Further, the drive rollers 38, 40 and 42, the reference roller 56, and the magnetic gap roller 54 are configured such that a part of the peripheral side surface of the lower conveyance guide 34D is formed in the conveyance path 32 from a hole formed in the lower conveyance surface 34AD. It is exposed to the side. Further, the driving rollers 38, 40 and 42, the reference roller 56, and the magnetic gap roller 54 are actively rotated by a driving force transmitted from an actuator (not shown).

  On the other hand, the driven rollers 44, 46 and 48 and the thickness detection roller 58 are rotatable about the central axis in the left-right direction at locations facing the driving rollers 38, 40 and 42 and the reference roller 56 in the upper conveyance guide 34U.

The driven rollers 44, 46 and 48 and the thickness detection roller 58 are pressed against the driving rollers 38, 40 and 42 and the reference roller 56 by compression springs (not shown), respectively. For this reason, the driven rollers 44, 46 and 48 and the thickness detection roller 58, when the bill BL is transported along the transport path 32, are transferred to the drive rollers 38, 40 and 42 and the reference roller 56, respectively. Press. The drive rollers 38, 40 and 42, the magnetic gap roller 54, and the reference roller 56 convey the bill BL in the front-rear direction along the conveyance path 32 by transmitting the rotational force to the bill BL.

  In the magnetic detection unit 50, a magnetic sensor 52 is disposed on the upper side of the conveyance path 32. The magnetic gap roller 54 is arranged such that the gap between the outer peripheral surface 54A and the detection surface 52A of the magnetic sensor 52 is about 2 to 5 times the bill thickness. The bills BL are printed using magnetic ink that is locally magnetic. Therefore, the magnetic detection unit 50 detects the magnetism of the bill BL conveyed on the conveyance path 32 by the magnetic sensor 52 and sends the detection result to the control unit 12. In response to this, the control unit 12 determines the authenticity or denomination of the banknote using the magnetic detection result of the banknote BL acquired from the magnetic sensor 52.

The displacement sensor 59 detects the relative displacement amount of the thickness detection roller 58 with reference to the position when the thickness detection roller 58 contacts the reference roller 56, and sends the detection result to the control unit 12. The control unit 12 compares the detection result with the reference value of the thickness stored in advance to determine whether the displacement amount corresponds to one bill or a plurality of bills. The presence or absence of pasting of etc. is judged.

  With this configuration, the thickness detection unit 60 causes the thickness detection roller 58 to come into contact with the reference roller 56 by the action of the compression spring when nothing is transported to the transport path 32. As a result, the thickness detection roller 58 receives the rotational driving force from the reference roller 56 and rotates in accordance with the rotation of the reference roller 56. At this time, the thickness detection unit 60 can detect that the thickness detection roller 58 is positioned at a reference height by the displacement sensor 59 and send the detection result to the control unit 12. On the other hand, in the thickness detection unit 60, when the bill BL is transported to the transport path 32, the bill BL is sandwiched between the thickness detection roller 58 and the reference roller 56. Thus, the thickness detection roller 58 is displaced upward. At this time, the thickness detection unit 60 detects the amount of displacement of the thickness detection roller 58 by the displacement sensor 59 and sends the detection result to the control unit 12.

  The banknote image detection unit 53 includes an upper reflection / transmission sensor unit 53U located on the upper side and a lower reflection / transmission sensor unit 53D located on the lower side. The banknote image detection unit 53 detects a reflection pattern and a transmission pattern of the banknote BL, and sends the detection result to the control unit 12. In response to this, the control unit 12 uses the reflection pattern and the transmission pattern of the bill BL acquired from the bill image detection unit 53 to determine the authenticity and denomination of the bill BL, the degree of damage (loss), and the like. .
