Next, the discrimination unit 18 transmits driving force to the driving rollers 33C, 44C, 44B and 44A, the thickness reference roller 51, and the magnetic gap roller 73 by an actuator (not shown).

  When the bill BL is conveyed from the deposit / withdrawal unit 16 to the discrimination unit 18 via the deposit / withdrawal unit side delivery unit 80B, the discrimination unit 18 first sandwiches the bill between the driving roller 33C and the driven roller 45E and is driven by the driven roller 45E. The bill BL is pressed against the roller 33C to transmit a downward driving force, and the bill BL is moved downward and conveyed to the sorting mechanism 36. The bills BL are transported to the discrimination sensor transport path 43 </ b> A by changing their direction in the backward direction by hitting the upper sorting surface 36 </ b> A of the sorting mechanism 36.

  Subsequently, the discrimination unit 18 conveys the banknote BL backward through the discrimination sensor conveyance path 43A by the driving force of the driving roller 33C and the driven roller 45E, and pushes up the driven roller 45C by the banknote BL. As a result, the discriminating unit 18 sandwiches the banknote between the driving roller 44C and the driven roller 45C, presses the banknote BL against the driving roller 44C by the driven roller 45C, and transmits the driving force in the backward direction. Transport to the acquisition unit 70. Subsequently, the bill BL is conveyed without clogging a gap provided between the detection surface of the magnetic sensor 71 and the magnetic gap roller 73 by the driving force of the magnetic gap roller 73 of the magnetic information acquisition unit 70. While the bill BL passes through the magnetic information acquisition unit 70, the discrimination unit 18 acquires magnetic information such as magnetic ink on the surface of the bill BL by the magnetic information acquisition unit 70.

  Subsequently, the discrimination unit 18 conveys the bill BL backward by the driving force of the driving roller 44C and the driven roller 45C, and pushes up the driven roller 45B by the bill BL. As a result, the discrimination unit 18 sandwiches the banknote between the driving roller 44B and the driven roller 45B, presses the banknote BL against the driving roller 44B by the driven roller 45B, and transmits the driving force in the backward direction. It is conveyed to the acquisition unit 60. While the bill BL is conveyed to the optical information acquisition unit 60 and passes through the optical information acquisition unit 60, the discrimination unit 18 acquires image information such as a reflected image and a transmission image on the surface of the bill BL by the optical information acquisition unit 60. To do.

  Subsequently, the discrimination unit 18 conveys the bill BL backward by the driving force of the driving roller 44B and the driven roller 45B, and pushes up the driven roller 45A by the bill BL. As a result, the discrimination unit 18 sandwiches the banknote between the driving roller 44A and the driven roller 45A, presses the banknote BL against the driving roller 44A by the driven roller 45A, and transmits the driving force in the backward direction. It is conveyed to the information acquisition unit 50. Subsequently, the discrimination unit 18 conveys the bill BL backward by the driving force of the driving roller 44A and the driven roller 45A, and pushes up the thickness detection roller unit 52 by the bill BL. Accordingly, the discrimination unit 18 sandwiches the banknote between the thickness detection roller unit 52 and the thickness reference roller 51, and presses the banknote BL against the thickness reference roller 51 by the thickness detection roller unit 52, thereby driving the driving force in the backward direction. To communicate. While the bill BL passes through the thickness information acquisition unit 50, the discrimination unit 18 detects a change in the movement of the thickness detection roller unit 52 by the gap sensor 55, and acquires the thickness information of the bill BL.

  Thereafter, the discrimination unit 18 conveys the banknote BL backward by the driving force of the thickness detection roller unit 52 and the thickness reference roller 51, and feeds the bill BL backward to the discrimination unit 18 via the conveyance path delivery unit 80A. The control unit 12 acquires the information of the banknote BL acquired by the magnetic information acquisition unit 70, the optical information acquisition unit 60, and the thickness information acquisition unit 50 by a signal transmission unit (not shown), and the authenticity, denomination, and fouling of the banknote BL. The bill BL is transported to the temporary holding unit 20 and stored, or is transported to the deposit / withdrawal unit 16 and returned based on the discrimination result.

  Although the operation | movement when the banknote BL is conveyed at the time of a money_receiving | payment process was demonstrated above, the case where the banknote BL is conveyed to the banknote storage 26 or the rejection store | warehouse | chamber 28 from the temporary storage part 20 at the time of a storage process, and a payment process When the banknote BL is conveyed from the banknote storage 26 to the deposit / withdrawal unit 16 or the reject store 28 at the time, the discrimination unit 18 reverses the rotation direction of each roller with respect to the depositing process and appropriately sets the sorting mechanism 36. Switch.

[1-5. Effect]
Here, as a conventional banknote depositing and dispensing machine, as shown in FIG. 15 in which members corresponding to those in FIG. 3 are assigned the same reference numerals, a discrimination unit 218 and a transport unit 224 are used instead of the discrimination unit 18 (FIG. 3). There is something provided. The conveyance unit 224 has a rectangular parallelepiped shape and is configured to be detachable from the frame 211. The discrimination unit 218 has a rectangular parallelepiped shape and is configured to be detachable from the frame 211 disposed behind the transport unit 224. Between the discrimination part 218 and the conveyance part 224, the delivery part 280G which delivers a banknote between this discrimination part 218 and this conveyance part 224 is formed.

  The bill BL passes through the delivery unit 280G between the discrimination unit 218 and the transport unit 224. Here, in order to acquire information with high accuracy in the optical information acquisition unit 60 and the magnetic information acquisition unit 70, it is desirable to reduce the variation in information due to the difference in the vertical position of the banknote BL. For this reason, it is desirable that the vertical width of the conveyance path 243 of the discrimination unit 218 be narrow enough to prevent the banknote BL from jamming (paper jam). However, since the vertical positions of the transport unit 224 and the discrimination unit 218 may not match due to manufacturing variation of parts, etc., if the vertical width of the transport path 243 is narrowed, the bill BL is jammed in the delivery unit 280G. There is a possibility.

  Moreover, since the delivery part 280G exists in the discrimination part 218 and the conveyance part 224, the distance between the drive rollers 33B and 33C and the drive roller 44C will become long. For this reason, the discrimination unit 218 and the transport unit 224 have a complicated configuration in which the number of components cannot be reduced because the driving roller 234B and the driven roller 245B need to be disposed on the front side of the delivery unit 280G, and the front-rear direction The length of was long.

  On the other hand, as a conventional banknote depositing and dispensing machine, as shown in FIG. 16 in which members corresponding to those in FIG. 15 are assigned the same reference numerals, a discrimination unit 318 is provided instead of the discrimination unit 218 (FIG. 15). . Compared with the discrimination unit 218, the discrimination unit 318 is omitted the drive roller 44C and the driven roller 45C. Since the driving roller 44C and the driven roller 45C are omitted from the discrimination unit 218, the discrimination unit 318 has a length in the front-rear direction corresponding to the space occupied by the drive roller 44C and the driven roller 45C than the discrimination unit 218. Can also be shortened.

  However, as for the discrimination part 318 and the conveyance part 224, the driving roller 234B and the driven roller 245B that are arranged in the nearest vicinity of the upstream side of the magnetic information acquisition part 70 at the time of deposit processing are provided in the conveyance part 224 instead of the discrimination part 318. It becomes.

  In general, the magnetic information acquisition unit 70 performs sensor output adjustment and inspection by a discrimination unit 318 alone that does not include the transport unit 224, and stores information such as basic output. Moreover, since the magnetic information acquisition part 70 can detect the weak magnetic reaction of the banknote BL, it is very sensitive. Therefore, when the discriminating unit 318 and the conveying unit 224 are mounted on the frame 211 and the driving roller 234B and the driven roller 245B are rotated, the metal portions of the driving roller 234B and the driven roller 245B of the conveying unit 224 are magnetized. If the metal foreign matter is attached, the magnetic information acquisition unit 70 detects the magnetic information as a noise component, and the detection of the magnetic information is performed more than the condition of the sensor output adjustment or inspection performed by the discrimination unit 318 alone. Performance will deteriorate.

  On the other hand, the discrimination unit 18 combines the discrimination connection transport unit 30 and the discrimination sensor unit 40, and functions as the driving roller 234B and the driven roller 245B, the driving roller 44C, and the driven roller 45C (FIG. 15) in the discrimination unit 218. By consolidating the drive roller 44C and the driven roller 45C (FIG. 3), the drive roller 234B and the driven roller 245B can be omitted. Therefore, the length of the conveyance path 43 in the front-rear direction can be shortened, and the apparatus size can be reduced. .

  Moreover, the discrimination part 18 comprised the discrimination connection conveyance part 30 and the discrimination sensor part 40 so that attachment or detachment was possible. Thereby, the discrimination part 18 can replace | exchange the discrimination sensor part 40 easily like the conventional discrimination parts 218 and 318, and can maintain maintainability.

  In addition, the discrimination unit 18 combines the discrimination connection conveyance unit 30 and the discrimination sensor unit 40, thereby moving the discrimination upper conveyance guide 41 provided above the discrimination sensor conveyance path 43 </ b> A from the distribution mechanism 36 rather than the reading unit 76. A separate lower conveyance guide 42 provided below the identification sensor conveyance path 43A is integrally formed without being divided from the rear side, which is the separated side, to the deposit / withdrawal section side delivery section 80B via the distribution mechanism 36. From the rear side of the reading means 76, it is formed integrally without being divided up to the rejection store delivery section 80C via the sorting mechanism 36. Thus, the discrimination part 18 forms the conveyance path 43 where the discrimination sensor conveyance path 43A branches into the deposit / withdrawal part side conveyance path 43C and the reject warehouse side conveyance path 43D without passing through the delivery part. As a result, the discrimination unit 18 has a structure that does not have the delivery unit 280G like the discrimination unit 218 (FIG. 15) and the discrimination unit 318 (FIG. 16), thereby reducing jamming and improving conveyance quality. The length of the conveyance path 43 in the front-rear direction can be shortened, and the apparatus size can be reduced.

  The discrimination unit 18 includes the drive roller 44 </ b> C and the driven roller 45 </ b> C upstream of the magnetic information acquisition unit 70 in the discrimination sensor unit 40 instead of the discrimination connection transport unit 30. As a result, the discrimination unit 18 can detect the states of the driving roller 44C and the driven roller 45C that are included in the discrimination sensor unit 40 and have a guaranteed positional accuracy when the discrimination sensor unit 40 is inspected alone. Information detection performance can be improved.

  According to the above configuration, the discrimination unit 18 forms the discrimination sensor conveyance path 43A as the discrimination unit conveyance path through which the banknote BL as the paper sheet is conveyed, and the characteristic of the banknote BL is set in the discrimination sensor conveyance path 43A. The discrimination sensor unit 40 provided with the reading means 76 for reading and the discrimination sensor unit 40 are detachable, and the discrimination sensor unit 40 is attached to the discrimination sensor unit 40 so as to be connected to the discrimination sensor transport path 43A. The discrimination connection transport section 30 that forms the transport section transport path 43CD that transports the bills BL in a direction different from the discrimination sensor transport path 43A is provided.

  Thus, the discrimination unit 18 maintains the maintenance performance of the discrimination sensor unit 40 and the detection performance of the magnetic information acquisition unit 70 in the same manner as the conventional discrimination unit 218 and the conveyance unit 224, while the discrimination sensor conveyance path 43A and the deposit / withdrawal unit side. By not providing a delivery section between the transport path 43C and the reject warehouse side transport path 43D, the length of the transport path 43 in the front-rear direction is made shorter than the transport path 243, and the length of the apparatus in the front-rear direction is shortened. , Bill jam can be reduced.
