Further, the magnetic head 122 is provided so as to correspond to a plurality of roller portions 212 of the conveyance roller 120 described later. For example, each magnetic head 122 is provided to face each roller portion 212 on a one-to-one basis. It has been. And the magnetic head 122 detects the magnetism of the banknote conveyed on the magnetic sensor unit 118, and outputs the detection result to the above-mentioned control part 10. FIG. In the present embodiment, the magnetic heads 122 are not limited to be provided so as to face the roller portions 212 in a one-to-one relationship. For example, one magnetic head 122 includes a predetermined number of magnetic heads 122. It may be provided so as to face the roller portion 212.

(Conveying roller 120)
As shown in FIG. 7, the transport roller 120 is provided so as to maintain a predetermined distance from the magnetic sensor unit 118, and has a columnar shaft (rotary shaft) 210 that is elongated in the left-right direction, and a shaft And a plurality of annular roller portions 212 supported by (rotating shaft) 210. Furthermore, each roller part 212 is provided along the axis | shaft 210 so that it may leave | separate every predetermined spacing in the left-right direction. The shaft 210 is made of, for example, a nonmagnetic metal material, and can be rotated by transmitting a driving force via a driving motor (not shown) or a driving gear meshed with the driving motor. Each roller portion 212 is joined to the shaft 210 and can rotate integrally with the shaft 210. In the present embodiment, the transport roller 120 is not limited to having the plurality of roller portions 212, and may include one wide annular roller portion 212, for example.

  Furthermore, each roller part 212 is comprised by the elastic member in order to convey a banknote smoothly. Specifically, each roller portion 212 is preferably a member having a high frictional force against the banknote in order to effectively transmit the driving force to the banknote in contact with the banknote, and further, an abnormality such as double feeding. It is preferably a member that can be deformed depending on the thickness of the banknotes to be transported so that a plurality of banknotes can overlap and pass through the magnetic detection unit 114 smoothly due to the transport. Therefore, it is preferable that the elastic member is selected as a member constituting each roller portion 212. Furthermore, each roller part 212 which concerns on this embodiment is formed from the light transmissive elastic member which permeate | transmits light. More specifically, the light-transmitting elastic member that transmits light is a transparent or translucent elastic member, for example, a member that does not include a carbon material and is formed from silicon rubber, urethane rubber, or the like. . In this way, by forming each roller portion 212 from a light-transmitting elastic member that transmits light, it is possible to visually recognize foreign matter attached to the outer peripheral surface of the roller portion 212 or foreign matter contained therein. it can.

  By the way, in the conventional discrimination part, when magnetic foreign matter such as magnetic ink or metal powder adheres to the outer peripheral surface of the roller part of the transport roller, or when magnetic foreign matter is included inside the roller part, The magnetic force due to the magnetic foreign matter is detected by the above-described magnetic head, which hinders improvement in the accuracy of bill discrimination in the magnetic detection unit. Specifically, in various banknotes distributed in Japan and overseas, patterns and the like are printed using magnetic ink, but there are banknotes having a strong magnetic force and banknotes having a weak magnetic force. And in order to discriminate | determine accurately with respect to what banknote, it was calculated | required to raise the magnetic detection sensitivity of a magnetic head more. However, when the magnetic detection sensitivity of the magnetic head is increased, the magnetic head may detect the magnetic force even when the bill is not conveyed in the magnetic detection unit. As described above, the discrimination of the bills by magnetism is performed when the control unit stores in advance the detection result when there is no bill in the magnetic detection unit and the detection when the bill is conveyed by the magnetic detection unit. This is achieved by comparing the result. Therefore, when the magnetic detection unit obtains a detection result including both a result due to the magnetic force caused by the magnetic ink of the banknote and a result due to the magnetic force not attributable to the magnetic ink, the banknote cannot be properly identified. It will be. In order to avoid such a situation, the present inventors diligently studied. The reason why the magnetic head detects the magnetic force even when the bill is not conveyed in the magnetic detection unit is that the magnetic head adheres to the roller unit. Alternatively, it was found that the magnetic force due to a small amount of magnetic foreign matter contained therein was detected.

  The roller portion of the conventional transport roller has a high frictional force against the banknote and is formed of a deformable rubber material for smooth transport of the banknote. Conventional rubber materials for roller parts are synthesized by adding sulfur or the like to organic molecules (vulcanization) and crosslinking reaction. Generally, carbon is often added during vulcanization. Therefore, the rubber material is a black material that does not transmit light. In addition, the rubber material includes metal powder contained in a minute amount in the raw material, metal residue such as a catalyst used for synthesis, and metal powder generated by scraping a synthesis apparatus during synthesis ( For example, the metal fins of the stirrer may be scraped during stirring to generate metal powder). If the roller part contains metal powder, the roller part is made of a black rubber material. Therefore, the roller part is visually attached to or included in the roller part before or during assembly of the discrimination part. I can't notice the metal powder. In such a case, after the discrimination part is assembled, the discrimination part is operated first, and the magnetic head detects the magnetic force in a state where the bill is not conveyed in the magnetic detection part. The presence of the metal powder contained inside will be recognized. Furthermore, when the metal powder adheres to or is contained in the roller portion, the bill cannot be properly identified, so that the discrimination portion cannot be shipped as a defective product. As a result, this has contributed to an increase in the manufacturing cost of the discrimination section and the automatic transaction apparatus including the discrimination section.

  In addition, in order to improve the accuracy of banknote discrimination in the magnetic detection unit, when detecting magnetism from the magnetic ink printed on the entire banknote, the upper surface of the magnetic sensor unit in contact with the banknote is widened, It is conceivable to provide many heads. In this case, in order to appropriately maintain the gap between the magnetic sensor and the banknote, as the magnetic head is increased, a larger number of roller portions facing the magnetic head are provided. However, if the number of roller parts increases, the possibility of magnetic foreign matter adhering to or contained in the roller part as described above is increased according to the number of the roller parts. This will increase the possibility of increasing the discrimination section. Therefore, it is difficult to improve the accuracy of discrimination in the magnetic detection unit by providing more magnetic heads.

  However, in the present embodiment, by forming the roller part 212 from a light-transmitting elastic member, the magnetic foreign matter adhering to the outer peripheral surface of the roller part 212 or the magnetic foreign matter included in the roller part 212 is visually observed. You can notice. Specifically, in the manufacture of the conveyance roller 120 of the magnetic detection unit 114, a cylindrical roller member is cut at a predetermined interval to create a plurality of roller portions 212, and the created plurality of roller portions 212 are pivoted. This is done by attaching to 210. By forming the roller portion 212, that is, the cylindrical roller portion member from a light-transmitting elastic member, when the roller portion member is cut, the magnetic foreign matter contained therein may be noticed visually. For example, the roller member can be cut so as not to include the magnetic foreign matter, and a plurality of roller portions 212 not including the magnetic foreign matter can be created. Further, by forming the roller portion 212 from a light-transmitting elastic member, it is possible to visually recognize the magnetic foreign matter attached to the outer peripheral surface of the roller portion 212. Therefore, after removing the magnetic foreign matter from the outer peripheral surface, a plurality of magnetic foreign matters are removed. The roller portion 212 can be attached to the shaft 210. Accordingly, since it is possible to create the transport roller 120 having the roller portion 212 without magnetic foreign matter, even if the magnetic detection sensitivity of the magnetic head 122 of the magnetic sensor unit 118 facing the transport roller 120 is increased, the magnetic detection is performed. The magnetic head 122 does not detect the magnetic force in a state where the bill is not conveyed in the portion 114, and the magnetic detection portion 114 can appropriately distinguish the bill. Furthermore, according to the present embodiment, since a plurality of roller portions 212 that do not include magnetic foreign matters can be created, even if the number of roller portions 212 is increased, the possibility of increasing defective discrimination portions is not increased. Therefore, it is possible to provide more magnetic heads 122 and improve the accuracy of discrimination in the magnetic detection unit 114. That is, according to the present embodiment, the discrimination accuracy of the magnetic detection unit 114 can be further improved.

  In the present embodiment, the magnetic foreign matter attached to the outer peripheral surface of the roller portion 212 or the magnetic foreign matter contained in the roller portion 212 is visually checked before the operation of the assembled discrimination portion 34 is confirmed. Since it can be noticed, it can cope with the magnetic foreign matter. Therefore, it is possible to avoid performing an operation check on a defective discrimination unit 34 that cannot be shipped due to the presence of magnetic foreign matter, and as a result, the manufacturing cost of the discrimination unit 34 and the automatic transaction apparatus 1 including the same can be reduced. The rise can be suppressed.

  Moreover, in this embodiment, since the roller part 212 is formed from the light-transmitting elastic member, the roller is visually checked during maintenance of the automatic transaction apparatus 1 as compared with the case where it is formed from a black rubber material. It becomes easy to recognize the presence of the magnetic foreign matter attached to the portion 212. Therefore, even when a magnetic foreign matter adheres to the outer peripheral surface of the roller unit 212 while operating the automatic transaction apparatus 1, the maintenance staff recognizes the attached magnetic foreign matter and cleans the outer peripheral surface of the roller unit 212. Can be done quickly. As a result, it becomes easy to always keep the roller unit 212 clean, and the discrimination accuracy in the magnetic detection unit 114 can be maintained in a good state.

<< Modification >>
In the above-described first embodiment, the plurality of roller portions 212 of the transport roller 120 of the magnetic detection unit 114 are formed from a light-transmitting elastic member. However, in the present embodiment, the present invention is not limited to this. Instead, for example, as in the modification described below, at least one of the plurality of roller portions 212 only needs to be formed of a light-transmitting elastic member. Below, the modification of this embodiment is demonstrated with reference to FIG. FIG. 8 is an explanatory diagram for explaining the internal configuration of the magnetic detection unit 114a according to a modification of the present embodiment, and corresponds to FIG. 7 described above.

  The conveyance roller 120a according to this modification includes a plurality of roller portions 212a and 212b, and the plurality of roller portions (first roller portions) 212a are made of a light-transmitting elastic member as in the first embodiment. The other plurality of roller portions (second roller portions) 212b that are formed are formed of a light transmissive resin member. The light transmissive resin member is transparent or translucent, and has a higher hardness than the above-described light transmissive elastic member, and is made of, for example, polycarbonate or acrylic. In the present modification, the number of each of the plurality of roller portions 212a and 212b is not particularly limited, and is formed from at least one light-transmitting elastic member on the plurality of roller portions 212 of the conveying roller 120a. The roller part 212a and the roller part 212b formed of at least one light transmissive resin member may be included.

  Specifically, as described above, the above-described light-transmitting elastic member is deformed so as to correspond to the thickness of the bills to be transported in order to ensure smooth transport of the thick bills in the magnetic detection unit 114a. It is possible and has a high frictional force against the banknote. However, due to the characteristics, foreign matter (magnetic foreign matter or the like) tends to adhere to the outer peripheral surface of the light-transmitting elastic member. Therefore, in this modified example, in order to avoid such adhesion of foreign matter, the other plurality of roller portions 212b are formed of a light-transmitting resin member that does not easily cause foreign matter to adhere. In order to avoid adhesion of foreign matter, all of the plurality of roller portions 212 of the transport roller 120a may be formed from a light transmissive member. However, although the light-transmitting resin member can avoid adhesion of foreign matters as compared with the light-transmitting elastic member, since it has high hardness, it may be difficult to smoothly transport a thick banknote. Therefore, it is preferable not to form all of the plurality of roller portions 212 of the transport roller 120a from a light-transmitting resin member, but to form only a part thereof from the light-transmitting resin member. Furthermore, in order to guarantee smoother conveyance of banknotes, even when banknotes are conveyed through the center of the magnetic detection unit 114, the banknotes are conveyed biased to the right side region or the left side region of the magnetic detection unit 114. Even if it is a case, it is preferable to provide the roller part 212a formed from the light transmissive elastic member so that at least one of the roller parts 212a formed from the light transmissive elastic member touches the surface of the banknote.

  In this modification, the plurality of roller portions 212a are formed of a light transmissive elastic member, and the other plurality of roller portions 212b are formed of a light transmissive resin member, thereby maintaining smooth conveyance of banknotes. Adherence of foreign matter (magnetic foreign matter or the like) to the outer peripheral surface of each roller portion 212 can be avoided. In addition, since the light-transmitting resin member is less expensive than the light-transmitting elastic member, according to the present modification, the manufacturing cost of the discrimination section 34 can be suppressed.

  Moreover, in 1st Embodiment and its modification, it is not limited to the whole one roller part 212 being formed from a light transmissive member, For example, the outer peripheral surface and outer peripheral surface of the roller part 212 Only the nearby region may be formed of a light transmissive member. Specifically, in the present embodiment, it is only necessary to be able to visually recognize a magnetic foreign substance existing in a range that affects the magnetic detection by the magnetic head 122. Therefore, the range that affects the magnetic head 122, that is, magnetic It is only necessary to be able to visually recognize the magnetic foreign matter in the outer peripheral surface of the roller unit 212 existing in the range close to the head 122 and in the region near the outer peripheral surface. Therefore, in order to visually recognize the magnetic foreign matter in the region, only the outer peripheral surface of the roller portion 212 and the region near the outer peripheral surface are formed from the light transmissive member. Even in this case, it is possible to avoid magnetic foreign matters and further improve the discrimination accuracy of the magnetic detection unit 114 (114a).

  Furthermore, in 1st Embodiment and its modification, the axis | shaft 210 of the conveyance roller 120 (120a) may be formed from the transparent resin material. In this case, since the shaft 210 is formed of a resin material that is less expensive than the metal material, the magnetic foreign matter contained in the shaft 210 can be visually recognized while suppressing an increase in the manufacturing cost of the discrimination portion 34. Thus, the discrimination accuracy of the magnetic detection unit 114 (114a) can be further improved.

<< Second Embodiment >>
In order to further improve the discrimination accuracy of the magnetic detection unit 114, it is required to maintain a predetermined distance S between the magnetic head 122 and the outer peripheral surface of the roller unit 212 of the transport roller 120 (see FIG. 9). Therefore, in the conventional discrimination unit, even when a bill that is thicker than expected is transported in the magnetic detection unit, the surface of the bill to be transported is fixed with respect to the magnetic head by the deformation of the roller unit. I was trying to keep it at a distance. However, when a material that is easily deformed and has a large amount of deformation is used for the roller portion, due to the property of being easily deformed, even normal thickness banknotes can be easily deformed. Smooth conveyance and maintenance of good discrimination accuracy are difficult. On the other hand, when a material that is difficult to deform is used for the roller portion, it becomes difficult to smoothly convey a banknote that is thicker than expected into the magnetic detection portion due to the property of being difficult to deform. That is, with regard to the material of the roller part, there is a trade-off relationship between the maintenance of the conveyance force and the discrimination accuracy and the deformation, and the conveyance is performed for both a normal thickness bill and a bill thickness greater than expected. It has been difficult to smoothly convey the banknotes while maintaining the surface of the banknotes to be kept at a certain distance (interval) S with respect to the magnetic head.

  Therefore, in the present embodiment, the biasing member 300 that biases the shaft 210 of the transport roller 120 is not used by maintaining the transport force and the discrimination accuracy and deforming by selecting the material of the roller unit 212. By providing, the surface of the banknote conveyed is maintained at a constant distance S with respect to the magnetic head 122. That is, in the present embodiment, the material of the roller unit 212 is optimized for smooth conveyance and discrimination accuracy of a banknote having a normal thickness. The force member 300 corresponds to this. The second embodiment will be described below.

  In addition, in this embodiment, the structure of the automatic transaction apparatus 1 and the discrimination part 34 is common with 1st Embodiment, description of the automatic transaction apparatus 1 and the discrimination part 34 of 1st Embodiment, and FIG. 6 may be referred to. Therefore, the description about the structure of the automatic transaction apparatus 1 and the discrimination part 34 is abbreviate | omitted here.

  Next, a detailed configuration of the magnetic detection unit 114b according to the present embodiment will be described with reference to FIG. FIG. 9 is an explanatory diagram for describing the internal configuration of the magnetic detection unit 114b according to the present embodiment, and corresponds to FIG. 7 described above. The magnetic detection unit 114b according to the present embodiment has a structure in which a biasing member 300 or the like is added to the magnetic detection unit 114 of the first embodiment. In other words, the magnetic sensor unit 118 and the transport roller 120 are as follows. This is the same as in the first embodiment. Therefore, the description about the structure of the magnetic sensor unit 118 and the conveyance roller 120 is abbreviate | omitted here.

  An interval S between the roller unit 212 and the magnetic head 122 is a conveyance path in another region in the discrimination unit 34 in order to bring the bill closer to the magnetic head 122 and improve the detection accuracy of the magnetic force by the magnetic head 122. It is set to be narrower than the vertical interval 106. The said space | interval S respond | corresponds to the thickness of the banknote for several sheets, for example. In the present embodiment, as shown in FIG. 9, the shaft 210 of the conveying roller 120 is urged by the urging member 300 so that a predetermined distance S is maintained between the magnetic head 122 and each roller portion 212. Has been. The urging member 300 includes, for example, a torsion spring, a leaf spring, or the like.

  Specifically, the shaft 210 has two bearings 302 that are positioned at both ends of the shaft 210 and support the shaft 210, and the inner peripheral surface of the bearing 302 is formed smoothly, and the outer peripheral surface of the shaft 210 is Take it. The bearing 302 is biased by the biasing member 300 described above. The bearing 302 is urged downward by the urging member 300 and abuts against the abutting member 304 provided in the magnetic detection unit 114b, whereby the interval between the roller unit 212 and the magnetic head 122 is set at a predetermined interval. S can be maintained. Further, when a bill thicker than expected, for example, a bill thicker than the interval S is conveyed to the magnetic detection unit 114b, the urging force of the urging member 300 is pushed away by the bill, and the roller unit 212 is moved from the magnetic head 122. Move away. Therefore, even when the roller portion 212 is formed from a material that is difficult to deform, it is possible to respond to the thickness of the banknote conveyed by the urging member 300. Therefore, the magnetic detection unit 114b according to the present embodiment can maintain the conveyance force of banknotes and maintain good discrimination accuracy while being able to handle various banknote thicknesses.

  That is, according to the present embodiment, whether the banknote has a normal thickness or a banknote having a thickness larger than expected, the surface of the banknote to be transported is maintained at a constant distance S with respect to the magnetic head 122 and is smoothly smoothed. Therefore, it is possible to further improve the discrimination accuracy of the magnetic detection unit 114. In the present embodiment, the configuration for biasing the shaft 210 of the transport roller 120 so as to maintain a predetermined distance S between the magnetic head 122 and each roller portion 212 is the configuration shown in FIG. It is not limited and other configurations may be used.

<< Third Embodiment >>
While operating the automatic transaction apparatus 1, magnetic foreign matter entering from the outside or magnetic ink from banknotes may adhere to the outer peripheral surface of the roller portion 212 of the transport roller 120 of the magnetic detection unit 114. Such a magnetic foreign substance deteriorates the discrimination accuracy of the magnetic detection unit 114 as is apparent from the above description. Therefore, in a third embodiment described below, magnetic foreign matter adhering to the roller unit 212 is detected, and maintenance personnel (operators) are urged to clean the roller unit 212. In particular, in the present embodiment, since it is possible to inform maintenance personnel which roller unit 212 should be cleaned, the cleaning operation can be completed easily in a short time.

  In the present embodiment, the configuration of the automatic transaction apparatus 1, the discrimination unit 34, and the magnetic detection unit 114 is the same as that of the first embodiment, and the automatic transaction apparatus 1, the discrimination unit 34, and the magnetic field of the first embodiment. The description of the detection unit 114 and FIGS. 1 to 7 can be referred to. Therefore, the description about the structure of the automatic transaction apparatus 1, the discrimination part 34, and the magnetic detection part 114 is abbreviate | omitted here.

<Detailed Configuration of Control Unit 10>
In order to detect the magnetic foreign matter adhering to the outer peripheral surface of the roller unit 212, the control unit 10 described above has a plurality of functional blocks for foreign matter adhesion determination. Below, each function part of the control part 10 is demonstrated with reference to FIG.10 and FIG.11. FIG. 10 is a block diagram of the control unit 10 relating to foreign matter adhesion determination according to the present embodiment. FIG. 11 is an explanatory diagram illustrating an example of the magnetic feature amount M according to the present embodiment. As illustrated in FIG. 10, the control unit 10 includes an acquisition unit 402, a calculation unit 404, a determination unit 406, and a display control unit 408.

(Acquisition unit 402)
The acquisition unit 402 acquires the magnetic detection result (magnetic information) output from each magnetic head 122 for each magnetic head 122.

(Calculation unit 404)
The calculation unit 404 analyzes the detection result output from each magnetic head 122 and calculates the magnetic feature amount M. For example, the calculation unit 404 is configured such that each point (0 point, 1 point,..., N−1 point, n point) on the outer peripheral surface of the roller unit 212 while the conveyance roller 120 makes one turn with respect to the magnetic head 122. , N + 1 point) when the magnetic head 122 is opposed to the magnetic head 122, the magnetic detection result for each point of each magnetic head 122 and the magnetic detection unit 114 stored in advance by the control unit 10 when there is no bill. The difference from the magnetic detection result is calculated, and the magnetic feature amount M for each magnetic head 122 is acquired. For example, FIG. 11 shows a continuous display of the magnetic feature amount M at each point calculated by the calculation unit 404. In the case of FIG. 11, in the magnetic detection unit 114, the magnetic heads 122 are provided so as to face the roller units 212 on a one-to-one basis, and the detection results of the magnetic heads 122 are obtained from the magnetic heads 122. It can be regarded as a detection result of the roller part 212 facing one to one. Therefore, in FIG. 11, the result calculated by the calculation unit 404 is the magnetic feature amount M in each roller unit 212 (roller units 212-1, 212-2, 212-3, 212-4 in FIG. 11). It is shown. In FIG. 11, the horizontal axis of each magnetic feature amount M indicates a point on the outer peripheral surface of each roller portion 212, and the vertical axis indicates the magnitude of the difference in magnetic detection intensity (magnetic feature amount M).

(Determination unit 406)
The determination unit 406 determines whether or not the magnetic feature amount M obtained from the magnetic information acquired by each magnetic head 122 is within a predetermined range. When the magnetic feature amount M outside the predetermined range is obtained, the determination unit 406 determines that the magnetic foreign matter is attached to the roller unit 212 corresponding to the magnetic head 122 related to the magnetic feature amount M. To do.

(Display control unit 408)
The display control unit 408 controls the result determined by the determination unit 406 to be displayed on the maintenance operation display unit 16. For example, when the determination unit 406 determines that the magnetic foreign matter is attached to the roller unit 212, the display control unit 408 cleans the corresponding roller unit 212 with respect to the maintenance operation display unit 16. A guidance screen 50 (see FIG. 12) for guiding maintenance personnel (operator) is displayed.

<Operation>
Next, operation | movement of the magnetic detection part 114 of the discrimination part 34 which concerns on this embodiment is demonstrated with reference to FIG.11 and FIG.12. FIG. 12 is an explanatory diagram illustrating an example of the guidance screen 50 according to the present embodiment.

  The acquisition unit 402 rotates the transport roller 120 one or more times in a state where there is no banknote in the magnetic detection unit 114, and acquires the magnetic detection result detected by each magnetic head 122. Since each roller part 212 of the conveyance roller 120 is provided so as to correspond to each magnetic head 122, the detection result of each magnetic head 122 acquired while rotating the conveyance roller 120 one or more times is The state of the outer peripheral surface of the roller part 212 is shown.

  Next, the calculation unit 404 analyzes the detection result output from each magnetic head 122 and calculates each magnetic feature amount M as described above. Each calculated magnetic feature amount M is shown, for example, as shown in FIG. 11, and in detail, from the top in the figure, the roller unit 212-1, the roller unit 212-2, the roller unit 212-3, and the roller unit 212. A magnetic feature value M of -4 is shown. In FIG. 11, the magnetic feature amount M of the roller part 212-1, the roller part 212-2, and the roller part 212-4 changes flatly, indicating that no magnetism is detected. On the other hand, the magnetic feature amount M of the roller portion 212-3 includes a peak T where the difference in magnetic detection intensity is high, that is, indicates that magnetism is being detected.

  Then, the determination unit 406 determines whether each magnetic feature amount M is within a predetermined range. Specifically, for the magnetic feature amount M of the roller unit 212-1, the roller unit 212-2, and the roller unit 212-4, the magnetic detection intensity is within a predetermined range at all points. The determination unit 406 determines that no magnetic foreign matter is attached to these roller units 212. On the other hand, the magnetic feature amount M of the roller portion 212-3 includes a peak T in which the difference in magnetic detection intensity is outside a predetermined range, and therefore magnetic foreign matter is attached to the roller portion 212-3. Is determined.

  Further, based on the determination that the determination unit 406 determines that the magnetic foreign matter is attached to the roller unit 212-3, the display control unit 408 displays the maintenance operation display unit 16 on the maintenance operation display unit 16 as shown in FIG. Control is performed to display a guidance screen 50 that guides maintenance personnel (operators) so as to clean the roller section 212-3. The maintenance staff recognizes that the magnetic foreign matter has adhered to the outer peripheral surface of the roller part 212-3 by the guidance screen 50, and cleans the roller part 212-3. In the present embodiment, the guidance screen 50 is not limited to the screen shown in FIG. 12. For example, in order to notify the automatic transaction apparatus 1 that the operator has completed the cleaning work according to the display content. The operation completion button may be included.

  In the present embodiment, while operating the automatic transaction apparatus 1, magnetic foreign matter entering from the outside or magnetic ink from the banknotes adheres to the outer peripheral surface of the roller portion 212 of the conveyance roller 120 of the magnetic detection unit 114. Even in this case, the magnetic foreign matter attached to the roller unit 212 can be detected, and the maintenance staff (operator) can be urged to clean the roller unit 212. Therefore, according to this embodiment, it is possible to maintain the discrimination accuracy of the magnetic detection unit 114 better. Furthermore, according to the present embodiment, it is possible to clearly display which roller unit 212 has a magnetic foreign substance attached thereto, and therefore, it is only necessary to perform a cleaning operation on the corresponding roller unit 212. The work can be completed easily in a short time, and the discrimination accuracy of the magnetic detection unit 114 can be maintained better.

  Note that this embodiment may be implemented not only in the first embodiment, but also in combination with the above-described modification of the first embodiment, the second embodiment, or the like.
