  The inside of the banknote deposit / withdrawal unit 110 is divided into a banknote feeding unit 112 and a banknote stacking unit 113 by a partition plate 111. The bill feeding unit 112 includes a feeding mechanism that feeds a bill inserted by a user to the transport path 140. The banknote stacking unit 113 includes a stacking mechanism for stacking banknotes transported from the transport path 140.

  The banknote recognition unit 120 is disposed on the conveyance path 140. The banknote identification part 120 identifies whether it is a denomination of a banknote conveyed by the conveyance path 140, and a reject banknote. The reject banknote is, for example, a genuine note with excessive damage or contamination, a counterfeit note (non-authentic note), a plurality of stacked bills, a skew or shifted bill, and the like. The banknote recognition unit 120 outputs the identification result to the control unit 160. A specific configuration of the banknote recognition unit 120 will be described later with reference to FIG.

  The temporary storage 130 includes a stacking mechanism, and temporarily stores the bills inserted into the bill deposit / withdrawal unit 110 until the transaction is completed. The forgotten banknote storage 150 is a storage for storing banknotes that the user forgot to take when depositing / withdrawing.

  The conveyance path 140 conveys banknotes between each of the units 110, 120, 130, and 150 of the upper unit 101u and the recycle boxes 181 to 183, the reject box 184, and the loading box 185 of the safe unit 101c. The transport path 140 includes a plurality of transport rollers and a motor (not shown) for rotating these transport rollers in both directions, and can transport bills in both directions. The transport path 140 switches the transport path by a plurality of gates. A plurality of sensors for detecting passage of banknotes are arranged on the conveyance path 140, and the conveyance status of banknotes on each conveyance path is monitored by the control unit 160.

  In the safe 101c, recycle boxes 181-183, reject boxes 184, and loading boxes 185 are stored in a line in the front-rear direction of the bill handling apparatus 101. The recycle boxes 181 to 183 are storage boxes for storing banknotes used for withdrawals by denomination. The recycle boxes 181 to 183 include a mechanism for accumulating and storing bills conveyed from the conveyance path 140 in the vertical direction and a mechanism for feeding the stored banknotes to the conveyance path 140. The reject store 184 is a storage store for storing reject banknotes generated in deposit / withdrawal transactions.

The loading box 185 is a storage box for storing banknotes to be filled in the recycle boxes 181 to 183 and for storing banknotes collected from the recycle boxes 181 to 183. The reject store 184 may be omitted. Moreover, although the banknote handling apparatus 101 is provided with the four recycle stores 181-183, the number of recycle stores can be set arbitrarily.

  The control unit 160 is configured as a microcomputer having a CPU, a memory, and the like inside, and according to a program prepared in advance based on the identification result by the banknote recognition unit 120, the banknote transport status on each transport path, and the like. The operation of the handling device 101 is controlled. The control unit 160 of the present embodiment executes a cleaning process for cleaning the surface of the banknote recognition unit 120 with banknotes by controlling the rotation speed of the transport rollers arranged in the transport path 140.

  The time management unit 170 is a device for managing the current time, and transmits a start signal to the control unit 160 when the current time becomes the preset cleaning process start time. Further, when the current time becomes the preset end time of the cleaning process, an end signal is transmitted to the control unit 160. The time management unit 170 may be configured as a part of the control unit 160 or may be configured separately. When the control unit 160 receives a start signal from the time management unit 170, the control unit 160 starts a cleaning process to be described later, and when receiving an end signal from the time management unit 170, the control unit 160 ends the cleaning process.

  FIG. 3 is an explanatory view illustrating the vicinity of the bill recognition unit. The conveyance path 140 is formed between a pair of guide plates 141, and in the vicinity of the bill recognition unit 120, three roller pairs (a first roller pair 145, a second roller pair 146, and a third roller pair 147). It has. Each of the three roller pairs 145 to 147 is composed of a pair of rollers facing each other in a direction orthogonal to the transport direction of the transport path 140 (the left-right direction in FIG. 3). Each roller is provided with a plurality of cylindrical transport roller bodies rb mounted at intervals on the rotation axis ax, and is configured to be bi-directionally rotatable by a drive unit (not shown). Each of the roller pairs 145 to 147 feeds the banknote S in the transport direction by the rotation of the roller pair while the banknote S is held between the pair of rollers.

  On the conveyance path 140, the first roller pair 145, the second roller pair 146, and the third roller pair 147 are arranged in this order. Hereinafter, for convenience of explanation, in the conveyance direction of bills by the conveyance path 140 (left and right direction in FIG. 3), the first roller pair 145 side (left direction in FIG. 3) is the upstream side and the second roller pair 146 is upstream. The description will be made assuming that the third roller pair 147 side (the right direction in FIG. 3) is the downstream side. The bill identifying unit 120 is disposed between the second roller pair 146 and the third roller pair 147 and is adjacent to the second roller pair 146 and the third roller pair 147, respectively. The first roller pair 145 and the second roller pair 146 are adjacent to each other. The distance D between the first roller pair 145 and the second roller pair 146 is configured to be narrower (D <W) than the width W in the conveyance direction of the bills conveyed on the conveyance path 140. .

  Here, the distance D between the first roller pair 145 and the second roller pair 146 is the second roller from the point (nip position) where the rollers are in contact with each other in the first roller pair 145. The distance in the conveyance direction to the nip position of the pair 146 is said. As the banknote width W here, for example, the banknote width that can be handled by the banknote handling apparatus 101 is the smallest banknote width. A section between the first roller pair 145 and the second roller pair 146 is also referred to as “first to second roller section”.

  A sensor 121 for identifying a banknote is disposed inside the banknote recognition unit 120. As the sensor 121, various sensors such as an optical sensor such as a transmissive optical sensor, a reflective optical sensor, a color sensor, an infrared sensor, and a UV sensor, and a magnetic sensor can be used. The sensor 121 may be configured by a combination of the various sensors described above. A part of the sensor 121 is exposed to the conveyance path 140 so as to directly face the banknote conveyed on the conveyance path 140. Hereinafter, the part exposed to the conveyance path 140 of the sensor 121 is referred to as an exposed part 121s. Here, the exposed portion 121s refers to a lens formed of a resin or glass that can transmit light and magnetism, a cover for protecting the lens, and the like. The sensor 121 acquires predetermined information from the banknote on the transport path 140 via the exposed portion 121s. The predetermined information refers to various information that can specify the type and state of the banknote, such as image data obtained by scanning the banknote, the magnetic characteristics of the banknote, and the optical characteristics with respect to ultraviolet rays. The sensor of the present embodiment is a transmissive sensor having a light emitting portion and a light receiving portion, and is disposed on both sides of the conveyance path 140, and exposed portions 121 s are formed on both sides of the conveyance path 140. In addition, the sensor 121 may be arrange | positioned only at the one side of the conveyance path 140 like a reflection type sensor.

  The cleaning process which the banknote handling apparatus 101 performs using FIGS. 4-7 is demonstrated. The cleaning process of the present embodiment is a process of cleaning the exposed part 121s of the sensor 121 by bringing the banknote into contact with the banknote recognition unit 120 by changing the conveyance speed of the banknotes of the roller pairs 145 to 147.

  FIG. 4 is an explanatory diagram illustrating a state in which the conveyance speed of the second and third roller pairs is slower than the conveyance speed of the first roller pair. The control unit 160 starts the cleaning process when a preset start condition is satisfied. Specifically, the control unit 160 sets the banknote transport speed V2 by the second roller pair 146, the banknote transport speed V3 by the third roller pair 147, and the banknote transport speed V1 by the first roller pair 145. The roller pairs 145 to 147 are rotated so as to be relatively slower than the above (V1> V2, V1> V3). In this embodiment, the transport speed V2 and the transport speed V3 are controlled to be equal. (V1> V2 = V3).

  The preset start condition is, for example, when a start signal is received from the time management unit 170 or when a signal for starting a process is received from the operation unit 105, and as a trigger for starting the cleaning process. Arbitrary conditions can be set. When reception of a signal from the time management unit 170 is set as a start condition, for example, the banknote handling device 101 feeds out banknotes from the recycle boxes 181 to 183 at a preset time, and the sensor 121 uses the banknotes fed out. The exposed portion 121s can be cleaned. The time for starting the cleaning process may be set by the operation unit 105.

  On the other hand, when reception of a signal from the operation unit 105 is a start condition, for example, the banknote handling apparatus 101 uses a banknote to be deposited when the user operates the operation unit 105 to perform a deposit process. Thus, the exposed portion 121s can be cleaned. In addition, the bill handling apparatus 101 can clean the exposed portion 121s with bills in the recycle boxes 181 to 183 at an arbitrary timing by operating the operation portion 105 by an attendant or the like, and can also supply a dedicated medium by inserting a cleaning-purpose medium. The exposed portion 121s can be cleaned using Further, the number of banknotes used for the cleaning process can be set by the operation unit 105 during the deposit process.

  At the time of normal transaction processing, the control unit 160 drives the roller pairs 145 to 147 so that the conveyance speeds V1 to V3 are equal (V1 = V2 = V3> 0) as shown in FIG. When starting the cleaning process from this state, the control unit 160 reduces the rotational speeds of the second roller pair 146 and the third roller pair 147 so that the transport speeds V2 and V3 are set higher than the transport speed V1. Slow down. On the other hand, when the control unit 160 starts the cleaning process from the state where the roller pairs 145 to 147 are not driven (V1 = V2 = V3 = 0), the control unit 160 determines the conveyance speed V2 of the second roller pair 146 and the third speed. The roller pairs 145 to 147 are driven so that the conveyance speed V3 of the first roller pair 147 is slower than the conveyance speed V1 of the first roller pair 145 (V1> V2 = V3).

  In the present embodiment, when the cleaning process is started, the control unit 160 also sets the first roller pair (not shown) on the downstream side of the third roller pair 147 among all the roller pairs arranged in the transport path 140. As with the second roller pair 146 and the third roller pair 147, control is performed so as to decelerate. The banknote handling apparatus 101 according to the present embodiment includes a first roller pair 145, a drive system that rotates a roller pair upstream of the first roller pair 145, a second roller pair 146, and a first roller pair. Two drive systems of a drive system for rotating the roller pair on the downstream side of the two roller pairs 146 are provided, and the control unit 160 controls the two drive systems separately.

  In addition, the drive system with which the banknote handling apparatus 101 is not limited to the above, Arbitrary drive systems may be comprised. Further, the control unit 160 may perform control different from that of the second roller pair 146 and the third roller pair 147 for a roller pair (not shown) on the downstream side of the third roller pair 147. The different control refers to, for example, control such that the conveyance speed is higher as the roller pair on the downstream side is faster than a roller pair (not shown), or control that is not decelerated with respect to at least some of the roller pairs.

  FIG. 5 is an explanatory view exemplifying a state in which a bill is bent between the first roller pair and the second roller pair. As described above, the distance D between the first and second roller sections is narrower than the width W in the transport direction of the bills transported through the transport path 140, and the transport speed V2 of the second roller pair 146 is the first. It is slower than the conveying speed V1 of one roller pair 145. Therefore, the banknote S which is the banknote drawn out from the recycle boxes 181 to 183 or the banknote deposited from the user is secondly sent out from the first roller pair 145 in the first to second roller sections. Bending occurs in the direction perpendicular to the conveying direction (up and down direction in FIG. 5) in order from the tip side in contact with the roller pair 146. FIG. 5 shows a state where the banknote S is bent in a wave shape. Thereafter, the bill S is sandwiched between the rotating second roller pair 146 while being bent in a direction orthogonal to the transport direction.

  FIG. 6 is an explanatory view illustrating the state of a bill fed out from the second roller pair. In the first to second roller sections, the banknote S is bent by the second roller pair 146 in a state of being bent in a direction orthogonal to the transport direction, and thus is held by the second roller pair 146. , Has residual stress inside. Therefore, when the sandwiching of the banknotes S is sequentially released on the downstream side of the second roller pair 146 due to the rotation of the second roller pair 146, the banknotes S are moved in the vertical direction in order from the front end side due to the residual stress ( It is fed out while swinging in the vertical direction in FIG. That is, the banknote S fed out from the second roller pair 146 is fed out in an upward oblique direction (upper right direction in FIG. 6) with respect to the transport direction (left and right direction in FIG. 6), and downward oblique direction (lower right direction in FIG. 6). ) Are repeated alternately.

  FIG. 7 is an explanatory view exemplifying a state in which a bill fed out from the second roller pair contacts the sensor. As described with reference to FIG. 6, the banknote S is fed out from the second roller pair 146 while swinging up and down. Therefore, also in the conveyance path 140 between the second roller pair 146 and the bill recognition unit 120, the tip of the bill S and other portions move to the downstream side while swinging in the vertical direction, so that the tip portion and other portions of the bill S are exposed portions of the sensor 121. Contact 121s. By this contact, the exposed portion 121s can be cleaned. The cleaning of the exposed portion 121s here means that the foreign matter such as dust or paper dust attached to the exposed portion 121s comes into contact with the banknote S, so that the foreign matter is separated from the exposed portion 121s, or the position where the foreign matter is attached. Means that the detection accuracy of the sensor 121 is improved. Thus, when the banknote S bends in a wave shape in the first to second roller sections, the banknote S moves while swinging up and down in the transport path 140 on the downstream side of the second roller pair 146. Therefore, even if the exposed portions 121s are formed on both sides of the transport path 140, both the exposed portions 121s can be cleaned.

  In addition, in the 1st-2nd roller area, when the banknote S bends in the shape of a mountain or a valley, the banknote S cannot swing up and down in the conveyance path 140 on the downstream side of the second roller pair 146. There is a case. However, even in this case, since the banknote S is fed out from the second roller pair 146 obliquely with respect to the transport direction, the tip end portion and other portions of the banknote S contact the exposed portion 121s of the sensor 121. The exposed portion 121s can be cleaned.

  In addition, the ability to clean the exposed part 121s of the sensor 121 can be further enhanced by increasing the swing width in the vertical direction of the bill S in the transport path 140 on the downstream side of the second roller pair 146. The up-and-down swing width (size of flutter) of the banknote S is the difference amount DE (DE = V1-V2) between the transport speed V1 of the first roller pair 145 and the transport speed V2 of the second roller pair 146. The bigger it is, the bigger it becomes. In the bill handling apparatus 101 of the present embodiment, the difference amount DE of the conveyance speed is set in the control unit 160 in advance, and the difference amount DE can be arbitrarily set by operating the operation unit 105 by an attendant or the like. The setting of the difference amount DE can also be set so as to change according to the number of banknotes used for the cleaning process. The bill handling apparatus 101 can arbitrarily set the distance from the second roller pair 146 to the sensor 121. Thereby, the position of the 2nd roller pair 146 or the sensor 121 can be adjusted so that the banknote drawn | fed out from the 2nd roller pair 146 may contact the exposed part 121s easily.

  The control unit 160 ends the cleaning process when a preset end condition is satisfied. Specifically, the control unit 160 sets the banknote transport speed V2 by the second roller pair 146, the banknote transport speed V3 by the third roller pair 147, and the banknote transport speed V1 by the first roller pair 145. The roller pairs 145 to 147 are rotated so as to be the same as (V1 = V2 = V3). Alternatively, the control unit 160 stops the rotation of the roller pairs 145 to 147. Thus, the cleaning process ends.

  Note that the preset termination condition is, for example, when a termination signal is received from the time management unit 170, or when a signal for terminating the process is received from the operation unit 105, a predetermined number of banknotes are Arbitrary conditions can be set, such as when passing through 120 or when transaction processing ends. When reception of a signal from the time management unit 170 is an end condition, the bill handling apparatus 101 automatically ends the cleaning process at a preset time. Further, when the reception of a signal from the operation unit 105 is set as an end condition, the bill handling apparatus 101 ends the cleaning process at an arbitrary timing by the operation of the operation unit 105. The time for ending the cleaning process can be set by the operation unit 105.

  The first roller pair 145 in this embodiment corresponds to the “first transport mechanism” in the claims. The second roller pair 146 in this embodiment corresponds to a “second transport mechanism” or a “roller pair” in the claims.

  According to the banknote handling apparatus 101 according to the first embodiment described above, since the banknote recognition unit 120 can be cleaned even when the automatic teller machine 100 is in a transaction, Cleaning can be performed without stopping operation. Also, with the banknote handling apparatus 101 of the present embodiment, it is not necessary for an operator or the like to attach a special medium other than a normal banknote such as a cleaning medium every time cleaning is performed. The identification unit 120 can be cleaned.

B. Second embodiment:
FIG. 8 is an explanatory view illustrating the vicinity of a bill recognition unit of the bill handling apparatus according to the second embodiment. FIG. 8 corresponds to FIG. 3 of the first embodiment. In the banknote handling apparatus 101 of the first embodiment, the first roller pair 145 is disposed adjacent to the upstream side of the second roller pair 146, but the banknote handling apparatus 101b of the second embodiment is the first Instead of the roller pair 145, a belt pair 148 is arranged. The belt pair 148 corresponds to a “first transport mechanism” in the claims. Since it is the same as that of the banknote handling apparatus 101 of 1st Example about the structure other than the belt pair 148 of the banknote handling apparatus 101b of 2nd Example, description is abbreviate | omitted.

  The belt pair 148 has a pair of transport belts that face each other in a direction orthogonal to the transport direction of the transport path 140 (left-right direction in FIG. 8). The belt pair 148 feeds the banknote S in the transport direction by the rotation of the belt while the banknote S is held between the pair of transport belts. The distance D2 between the belt pair 148 and the second roller pair 146 is configured to be narrower (D2 <W) than the width W in the transport direction of the bills transported through the transport path 140. Here, the distance D2 between the belt pair 148 and the second roller pair 146 is the distance from the downstream end (nip opening position) of the belt pair 148 where the conveyance belts are in contact with each other. The distance in the conveyance direction to the point (nip position) where the rollers are in contact with each other in one roller pair 145. A section between the first roller pair 145 and the belt pair 148 is also referred to as a “belt-roller section”.

  When the control unit 160 (FIG. 2) starts the cleaning process, the banknote transport speed V2 by the second roller pair 146 and the banknote transport speed V3 by the third roller pair 147 are transferred to the banknote 148 by the belt pair 148. The roller pairs 146 and 147 and the belt pair 148 are driven so as to be relatively slower than the speed V4 (V4> V2 = V3).

  As a result, the banknotes S are similarly fed from the leading end side while swinging in the vertical direction on the downstream side of the second roller pair 146. Therefore, the front-end | tip part and other part of the banknote S contact the exposed part 121s of the sensor 121, and foreign materials, such as dust and paper dust adhering to the exposed part 121s, can be cleaned. As described above, even when the first roller pair 145 of the first embodiment is replaced with the belt pair 148, the sensor 121 can be easily cleaned with the banknote.

C. Variations:
The present invention is not limited to the above-described examples and embodiments, and can be implemented in various modes without departing from the gist thereof. For example, the following modifications are possible.

C1. Modification 1:
The second roller pair 146 of the banknote handling apparatus 101 has a rotational force (torque) received from the banknote sent out from the first roller pair 145 until the rotational force becomes a predetermined value or less when the rotational force (torque) becomes a predetermined value or more. A mechanism for temporarily increasing the rotation speed may be provided.

  As a mechanism for temporarily increasing the rotational speed, for example, a ratchet mechanism or the like is provided between the second roller pair 146 and a driving unit (not shown), and torque is generated in the second roller pair 146 by the force received from the bill. In this case, the roller may idle by the torque. Further, the rotational force received by the second roller pair 146 from the bill is detected by the detection unit, and when the detected torque becomes a predetermined value or more, the control unit 160 temporarily sets the rotation speed of the second roller pair 146. The structure which raises automatically may be sufficient. By doing in this way, the bending of the banknote S in the first to second roller sections becomes larger than necessary, and the occurrence of a state in which the banknote is bent when the banknote is sandwiched by the second roller pair 146 is suppressed. Can do.

C2. Modification 2:
The start condition and end condition of the cleaning process may be conditions other than those exemplified in this embodiment. For example, the control unit 160 may execute the cleaning process when receiving two signals, a start signal from the time management unit 170 and a start signal from the operation unit 105. In this way, the cleaning process can be executed when a transaction process is performed within a predetermined time set in advance. The cleaning process may be appropriately executed by detecting the identification accuracy of the sensor 121 and the degree of contamination of the exposed portion 121s.

  The time management unit 170 may manage only the timer function without managing the current time. Moreover, the banknote handling apparatus 101 may not include the time management unit 170 and may execute the cleaning process only in response to an input from the operation unit 105.

C3. Modification 3:
In this embodiment, in the cleaning process, the control unit 160 sets the roller pairs 146 and 147 so that the conveyance speed V2 of the second roller pair 146 and the conveyance speed V3 of the third roller pair 147 are equal (V2 = V3). However, the conveyance speed V2 of the second roller pair 146 and the conveyance speed V3 of the third roller pair 147 may be different (V1 ≠ V3).

  Further, if there is a difference between the conveyance speed V1 of the first roller pair 145 and the conveyance speed V2 of the second roller pair 146, the bill S may be bent in the first to second roller sections. Therefore, only the transport speed V2 of the second roller pair 146 may be made slower than the transport speed V1 of the first roller pair 145, and the transport speed of the other roller pairs may not be made slower than the transport speed V1.

C4. Modification 4:
The banknote handling apparatus 101 may have a configuration capable of executing the cleaning process using the third roller pair 147 and the roll pair on the downstream side of the third roller pair 147. In addition, a belt pair may be used in place of the second roller pair 146 as long as the banknotes can be fed up and down. Further, the control unit 160 may be configured to incline the roller pair obliquely with respect to the transport direction in order to feed the banknote obliquely during the cleaning process.

C5. Modification 5:
In the present embodiment, the banknote handling apparatus 101 performs the cleaning process using banknotes, but the sensor 121 may be cleaned by bringing paper sheets other than banknotes into contact with the sensor 121. Moreover, although the banknote handling apparatus which handles a banknote was demonstrated in the present Example, this invention is not limited to a paper sheet handling apparatus, It is with respect to the paper sheet handling apparatus which handles paper sheets, such as a banknote and a security | security. Can be applied.
