Abstract

A dispensing part (4) is furnished with an interfering member (51) situated below a lower guide (34), and within a rotational trajectory (43) of a tongue (43) of a bladed wheel (41). Therefore, as the bladed wheel (41) is rotated in the dispensing part (4), the tongue (43) is first placed gradually into contact against the interfering member (51) in proximity to a lower end part (51P) thereof, and the tongue (43) is then slid against the interfering member (51). Thereafter, a medial part (43B) is brought into against a banknote (BL) transported within a transport path (32), gradually bringing about contact of an outside section thereof, until finally a distal end part (43A) is induced to bend slightly and strike against the banknote (BL). As a result, the dispensing part (4) can keep to a very low level the noise produced in association with striking of the distal end part (43A) of the tongue (43) and the banknote (BL). In so doing, the noise produced during accumulation of media may be minimized.

Description

Medium stacking apparatus and medium processing apparatus

The present invention relates to a medium stacking apparatus and a medium processing apparatus, and is suitable for application to, for example, a banknote processing apparatus (so-called teller machine) installed at a counter of a financial institution.

Conventionally, as a banknote processing apparatus, various transactions such as cash deposits and withdrawals are made with a customer by being operated by an operator such as a staff in charge of the counter (so-called teller) at a counter of a financial institution. Those that perform processing are widespread (for example, see Japanese Patent Application Laid-Open No. 2007-290850 (FIG. 1 and the like)).

The banknote handling apparatus includes, for example, a depositing unit for depositing banknotes, a withdrawal unit for dispensing banknotes, a transporting unit for transporting banknotes, and a discrimination unit for identifying the denomination and authenticity of the inserted banknotes. , A temporary storage unit for temporarily storing the inserted banknotes, a banknote cassette for storing banknotes for each denomination, and a reject cassette for storing banknotes that should not be reused. Moreover, the banknote processing apparatus is connected with the operation terminal etc. which an operator operates.

For example, when the banknote processing apparatus receives an instruction to withdraw money from the operator via the operation terminal, the banknote is paid out from the banknote cassette according to the amount of money to be withdrawn, and the banknote is transported to the discrimination section. Discrimination is performed, and normal banknotes are sequentially conveyed to the dispensing unit by the conveyance unit.

The dispensing unit sequentially accumulates the banknotes conveyed one by one by the conveyance unit, and when the banknotes to be dispensed are all accumulated, causes the operator to take out the banknotes.

For example, the dispensing unit 604 shown in FIG. 11 is provided with a stacking table 31 that is movable in the vertical direction in a stacking space 30S formed in the frame 30 and stacks banknotes on the stacking table 31.

Near the upper end of the rear side surface of the accumulation space 30S, a conveyance path 32 for conveying bills is formed. A discharge roller 36 that rotates in the direction of the arrow R1 and a pressure roller 38 that freely rotates are disposed at positions where the conveyance path 32 is sandwiched up and down in the vicinity of the front end of the conveyance path 32.

A plurality of impellers 41 are arranged on the left and right sides of the discharge roller 36. The impeller 41 has a plurality of elongated tongue pieces 43 attached radially from the central body 42 outward. The tongue piece 43 is made of, for example, a rubber material and bends easily. The impeller 41 is attached to the same rotation shaft 37 as the discharge roller 36 and rotates together with the discharge roller 36.

When the banknote is transported from the transport unit of the banknote processing apparatus, the dispensing unit 604 starts a stacking operation, transports the banknote forward along the transport path 32, and sets the discharge roller 36 and the pressing roller 38. It is sandwiched between and discharged into the accumulation space 30S.

The banknotes released into the accumulation space 30S collide with the bill stopper 40 provided at a position substantially opposite to the ejection roller 36 and the like in the accumulation space 30S and the momentum is absorbed, and then rotate together with the ejection roller 36. The rear end portion is knocked down by the tongue piece 43 of the impeller 41 and is accumulated on the accumulation table 31 or on the already accumulated banknotes.

However, in this dispensing part 604, due to its structure, the rotation trajectory 43R drawn by the outer end of the tongue piece 43 of the impeller 41 during rotation and the banknote transport path in the transport path 32 intersect.

For this reason, in the dispensing unit 604, during the stacking operation, the tongue 43 of the rotating impeller 41 is struck against the banknote on the conveyance path 32, and a striking sound is generated. Thus, the dispensing unit 604 has a problem that a large noise is generated during the dispensing operation.

The present invention has been made in consideration of the above points, and intends to propose a medium stacking apparatus and a medium processing apparatus that can suppress noise generated when stacking media.

In order to solve this problem, in the medium stacking apparatus of the present invention, a transport path for transporting a paper-like medium, a discharge section for discharging the medium transported through the transport path into a predetermined stacking space, A stacking base on which the medium discharged from the discharge section is placed and stacked, and a flexible tongue piece in the radial direction from a central body that rotates about a central axis perpendicular to the medium transport direction. The rear end of the medium extended from the discharge portion is positioned inside the rotation locus drawn when the outer end portion farthest from the central body of the tongue piece rotates in a circular shape, and is placed on the transport path. An impeller disposed so as to intersect the rotation trajectory, and a conveyance path that is located inside the rotation trajectory, deforms the tongue piece when the impeller rotates, and returns the tongue piece to its original shape. And an interfering member to be brought into contact with the inside medium.

In the medium processing apparatus of the present invention, the storage unit that stores the sheet-shaped medium, the transport path that transports the medium supplied from the storage unit, and the medium that has been transported through the transport path into the predetermined accumulation space. Flexible from a discharge unit that discharges, a stacker that is provided in the stacking space and on which the medium discharged from the discharge unit is placed and stacked, and a central body that rotates about a central axis perpendicular to the conveyance direction of the medium Of the rotating trajectory drawn when the outer end furthest from the central body of the tongue piece rotates in a circular shape. An impeller positioned inside and arranged to intersect the rotation path with respect to the conveyance path, and positioned inside the rotation path and deforming the tongue piece when the impeller rotates, An interference member that abuts against the medium in the conveyance path before returning to the original shape It was so.

In the present invention, when the tongue piece is brought into contact with the medium in the conveyance path by the rotation of the impeller, the tongue piece is brought into contact with the interference body in advance to be deformed and brought closer to the central axis, thereby reducing the speed. Can be made.

According to the present invention, when the tongue piece is brought into contact with the medium in the conveyance path by the rotation of the impeller, the tongue piece is brought into contact with the interference body in advance and deformed so as to be close to the central axis, thereby increasing the speed. Can be reduced. Thus, the present invention can realize a medium stacking apparatus and a medium processing apparatus that can suppress noise generated when stacking media.

[2. Internal configuration of banknote processing apparatus]
Next, the internal configuration of the banknote handling apparatus 1 will be described with reference to FIG. In the housing 2 of the banknote handling apparatus 1, in addition to the control unit 8 described above, a discrimination unit 11, a temporary storage unit 12, banknote cassettes 13A to 13D, a reject cassette 14 and a transport unit 15 are provided.

The discrimination unit 11 is arranged on the lower rear side of the depositing unit 3. The discrimination unit 11 is a normal banknote that can be handled or rejected that cannot be handled based on the denomination, authenticity, correctness, running state, etc. of the banknote conveyed by the transport unit 15. It discriminate | determines whether there exists and sends out the discrimination result to the control part 8. FIG.

The temporary storage unit 12 is disposed on the lower front side of the dispensing unit 4, temporarily holds the banknotes transported by the transport unit 15, and transports the banknotes held one by one. 15 to send.

In the lower part of the housing 2, a reject cassette 14 is disposed on the foremost side, and

The banknote cassettes 13A to 13D stack the banknotes (normal banknotes) conveyed from the conveyance unit 15 in the vertical direction and store them inside, and feed out the banknotes stored one by one to the conveyance unit 15. .

The reject cassette 14 collects and stores reject banknotes conveyed from the conveyance unit 15 inside.

The conveyance unit 15 includes various rollers and belts arranged along a conveyance path W that connects each part in the housing 2, and a gear and a motor for driving these rollers. Moreover, the conveyance part 15 has arrange | positioned the conveyance path switching mechanism which is not shown in figure at the branch point of a conveyance path.

The transport unit 15 transports banknotes along the transport path W based on the control of the control unit 8 and switches the transport destination of the banknotes by the transport path switching mechanism. Incidentally, in FIG. 3, only a part of the parts constituting the transport unit 15 is schematically shown.

With this configuration, when the deposit processing is performed, the bill processing apparatus 1 first causes the operator to insert bills into the deposit unit 3, separates them one by one, and sequentially sends them out to the transport unit 15. The transport unit 15 sequentially transports the banknotes to the discrimination unit 11 along the transport path W.

The discrimination unit 11 discriminates the banknotes one by one and sends the discrimination result to the control unit 8. At this time, the control part 8 determines the conveyance destination of each banknote based on whether it is a discrimination result acquired from the discrimination part 11, ie, a normal banknote or a reject banknote.

The normal banknote is transported to the temporary storage section 12 by the transport section 15 and temporarily stored, and then transported to the discrimination section 11 again to determine the denomination and to the banknote cassettes 13A to 13D corresponding to the denomination.

The banknote handling apparatus 1 accepts an instruction for a withdrawal amount from the operation terminal 22 or 23 (FIG. 2) when a withdrawal process is performed, and responds to the withdrawal amount from the bill cassettes 13A to 13D based on the control of the control unit 8. The denominations and the number of banknotes are sequentially fed out to the transport unit 15.

The transport unit 15 discriminates the denominations and correctness of the fed banknotes by the discrimination unit 11 and then sequentially delivers them to the withdrawal unit 4 (4A or 4B). The withdrawal unit 4 accumulates the banknotes delivered from the transport unit 15 and causes the operator to take out the banknotes.

In this way, the banknote handling apparatus 1 sequentially conveys the banknotes to the withdrawal unit 4 and accumulates them in the withdrawal process, and then causes the operator M to take out the banknotes from the withdrawal unit 4.

[3. Composition of withdrawal section]
Next, the configuration of the dispensing unit 4 will be described. As shown in FIGS. 4 and 5, the dispensing portion 4 has a configuration in which various components are attached in a rectangular parallelepiped frame 30.

Incidentally, FIG. 4 shows a right side view of the dispensing unit 4, and FIG. 5 shows a plan view. For convenience of explanation, each part is simplified, and some parts are omitted or transmitted.

The frame 30 (FIG. 4) has a rectangular parallelepiped integrated space 30S formed therein. In the accumulation space 30S, an accumulation table 31 made of a thin plate member is provided in the vertical direction. The stacking table 31 is arranged such that its plate surface is inclined with respect to the horizontal direction, and the projection shape in the left-right direction is a substantially parallelogram. Moreover, 31 A of accumulation surfaces which are the upper surfaces of the collection stand 31 can accumulate | store the banknote BL.

The stacking table 31 is moved in the vertical direction by the stacking table moving unit (not shown) based on the control of the control unit 8 (FIG. 1).

On the other hand, as shown in FIG. 4, a conveyance path 32 is formed on the upper rear side of the dispensing unit 4 to communicate between the upper rear surface of the frame 30 and the upper rear side surface of the accumulation space 30S in the front-rear direction. Yes. The transport path 32 has a cross-sectional shape that matches the banknote BL.

An upper guide 33 and a lower guide 34 for guiding the banknote BL along the transport path 32 are provided above and below the transport path 32. The upper guide 33 reaches from the rear surface of the frame 30 to a front position on the ceiling surface of the accumulation space 30S. On the other hand, the lower guide 34 reaches the rear surface of the accumulation space 30S from the rear surface of the frame 30, and is connected to a rear guide 35 that forms the rear surface of the accumulation space 30S.

On the lower side in the vicinity of the front end of the conveyance path 32, a discharge roller 36 is disposed. The discharge roller 36 is formed in a columnar shape with the central axis directed in the left-right direction, and penetrates the rotary shaft 37 at the central portion. Incidentally, as shown in FIG. 5, two discharge rollers 36 are passed through the rotation shaft 37 so as to be spaced apart from each other.

The rotating shaft 37 is adapted to transmit a driving force from an actuator (not shown), and rotates in the direction of the arrow R1 together with the discharge roller 36 based on the control of the control unit 8 (FIG. 1).

A pressure roller 38 is provided at a position on the upper side in the vicinity of the front end of the conveyance path 32 and facing each discharge roller 36. The pressing roller 38 is formed in a cylindrical shape with the central axis directed in the left-right direction. Further, as shown in FIG. 5, the pressure roller 38 is narrower in the left-right direction than the discharge roller 36.

Further, the pressing roller 38 is penetrated by the rotation shaft 39 at the center portion thereof, and freely rotates around the rotation shaft 39.

The rotary shaft 39 is pressed downward by a spring (not shown). Therefore, the pressing roller 38 is urged toward the discharge roller 36, and when the discharge roller 36 rotates in the arrow R1 direction, it rotates in the arrow R2 direction due to friction. Moreover, if the banknote BL exists in the conveyance path 32 at this time, the discharge | emission roller 36 will pinch | interpose the said banknote BL between the press rollers 38, will be conveyed forward, and will discharge | release it in the accumulation space 30S.

Incidentally, the dispensing unit 4 can discharge the bills BL into the stacking space 30S at an extremely high speed, for example, 12 sheets per second, and can stack the bills BL on the stacking table 31 at the same speed.

A bill stopper 40 is provided in front of the accumulation space 30S. The bill stopper 40 is attached to the front surface of the frame 30 via a spring (not shown).

For this reason, when the bill BL discharged into the accumulation space 30S by the discharge roller 36 and the pressing roller 38 collides, the bill stopper 40 absorbs the impact and pushes it back slightly.

Incidentally, in addition to the discharge roller 36, the impeller 41 (FIG. 4) is passed through the rotary shaft 37. The impeller 41 extends four tongue pieces 43 radially outward from a cylindrical central portion 42 attached to the rotary shaft 37.

The tongue piece 43 is formed in a thin and elongated plate shape by a material such as rubber, and has flexibility and a relatively large frictional force on the surface. Further, the tongue 43 has a strength enough to return to its original shape when deformed, so-called “koshi”, and is made of a flexible material.

Incidentally, as shown in FIG. 5, the rotary shaft 37 has a total of five, one between the left and right discharge rollers 36 and two on the outside of the left and right discharge rollers 36 with unequal intervals. Has been placed.

The impeller 41 is rotated in the direction of the arrow R1 together with the discharge roller 36 when the rotary shaft 37 is rotated. At this time, the tongue piece 43 is rotated so that the outer end portion 43A draws a circle along the rotation locus 43R without being deformed if no other parts are provided within the rotation radius. Will do.

If the bill BL that has been released into the stacking space 30S and collided with the bill stopper 40 is within the range of the rotation trajectory 43R, the tongue piece 43 is moved downward, that is, on the upper surface of the stacking table 31 or on the stacking table 31. Tap on the top of the stacked bills BL. Subsequently, the tongue piece 43 can be bent so as to be in close contact with the upper surface of the banknote BL that has been knocked down, and can be pulled backward by applying a frictional force to the banknote BL.

Further, in the upper guide 33, the lower guide 34, and the rear guide 35, a hole for allowing the tongue piece 43 to pass without interfering with the tongue piece 43 is appropriately drilled at a position where the tongue piece 43 passes when the impeller 41 rotates. It is installed.

In addition to such a configuration, the dispensing part 4 has an interference member at a position corresponding to the impeller 41 below the lower guide 34 and inside the rotation locus 43R, that is, at a position where the tongue piece 43 of the impeller 41 abuts. 51 is provided.

The interference member 51 is formed of a strong metal plate with the plate surface facing in the front-rear direction and sufficiently thick, and does not easily bend, that is, does not vibrate easily.

The interference member 51 has a shape in which the lower portion is bent slightly forward, and the projection shape in the left-right direction is a polygonal line. In other words, the vicinity of the lower end 51P of the interference member 51 is an inclined surface in which the normal is inclined toward the rotation axis 37 with respect to the tangent to the rotation locus 43R as will be described later.

Furthermore, the lower end 51P of the interference member 51 is extended to the outside of the rotation locus 43R, and the upper end 51Q is close enough to leave a slight gap with respect to the lower guide 34.

By the way, as shown in FIG. 5, the interference member 51 includes an interference member 51A corresponding to the two left impellers 41, the central one impeller 41, and the two right impellers 41, respectively. It is comprised by the member 51B and the interference member 51C.

That is, the area of the interference member 51 that does not correspond to the impeller 41, for example, the range that corresponds to the discharge roller 36, is omitted, so that the area thereof is minimized.

Thus, in the dispensing portion 4, the interference member 51 is provided in the range of the rotation locus 43R drawn when the tongue 43 of the impeller 41 rotates in a circular shape below the lower guide 34.

[4. Operation and effect]
In the above configuration, when the banknote BL is transported by the transport unit 15 (FIG. 3), the dispensing unit 4 according to the present embodiment releases it by rotating the rotating shaft 37 (FIGS. 4 and 5). The impeller 41 is rotated together with the roller 36 in the direction of the arrow R1.

Here, attention is paid to one tongue piece 43 among the four tongue pieces 43 provided on the impeller 41. As shown in FIG. 6A, the tongue 43 abuts the outer end 43 A farthest from the rotating shaft 37 in the vicinity of the lower end 51 P of the interference member 51 after passing through the rear guide 35.

6A shows only a part of the withdrawal unit 4 for convenience of explanation, and in particular, for the impeller 41, only one tongue piece 43 of interest among the four tongue pieces 43 is shown. The others are omitted.

Since the portion near the lower end 51P of the interference member 51 is slightly bent forward with respect to the upper portion, the normal line L1 is directed to the rotation axis 37 side with respect to the tangent line L2 of the rotation locus 43R. In other words, the vicinity of the lower end 51 P of the interference member 51 is formed so as to gradually enter the inner side from the outer side of the rotation locus 43 R along the traveling direction of the tongue piece 43 and approach the rotating shaft 37.

For this reason, as shown in FIG. 6B, the tongue piece 43 has the outer end 43 A side on the interference member 51 while gradually increasing the contact area with the interference member 51 as the impeller 41 rotates in the direction of the arrow R 1. It will be deformed to the shape along. For this reason, the tongue piece 43 hardly generates an impact sound when coming into contact with the interference member 51.

Thereafter, as the impeller 41 rotates, the tongue piece 43 increases the contact area with the interference member 51 while gradually moving the contact position with the interference member 51 upward, as shown in FIG. 7A. , A part thereof is exposed to the conveyance path 32. Here, when there is a bill BL in the conveyance path 32, the tongue piece 43 causes the middle portion 43B, which is a part of the middle, to contact the bill BL.

By the way, in the conventional withdrawal part 604 (FIG. 11), as described above, the outer end part 43A of the tongue piece 43 was first in contact with the banknote BL. Since the outer end portion 43A is farthest from the rotating shaft 37, the outer end portion 43A is the portion with the highest speed in the rotating impeller 41. Further, the outer end portion 43A is not fixed at all on the outer side (the side opposite to the rotating shaft 37 side) and is a so-called free end, so that vibration when colliding with other parts is relatively large. .

Due to these factors, in the conventional dispensing unit 604, the noise generated when the outer end 43A of the tongue piece 43 collides with the bill BL is relatively large.

On the other hand, in the tongue piece 43 of the dispensing unit 4 according to the present embodiment, the middle portion 43B that first comes into contact with the bill BL is positioned closer to the rotation shaft 37 than the rotation locus 43R, and the traveling speed in the rotation direction is rotated. It is lower than the outer end 43A on the locus 43R.

The middle portion 43B is fixed to the center portion 42 on the inner side (that is, the rotation shaft 37 side), and is in contact with the interference member 51 on the outer side (that is, the side that faces away from the rotation shaft 37). Can be considered as being. Thereby, the vibration at the time of the tongue piece 43 colliding with other components is significantly smaller than the case of what is called a free end.

For this reason, the withdrawal part 4 causes the noise generated when the middle part 43B of the tongue 43 collides with the banknote BL, and the outer end part 43A collides with the banknote BL along the rotation locus 43R in the conventional withdrawal part 604. It can be much smaller than the noise that is generated.

Thereafter, when the impeller 41 rotates together with the discharge roller 36, the tongue piece 43 comes into contact with the bill BL due to the friction generated between the bill BL and the bill BL as shown in FIG. 7B. While gradually increasing the area and decreasing the area in contact with the interference member 51, it proceeds forward at the same speed as the bill BL.

Eventually, the outer end portion 43A of the tongue piece 43 is separated from the upper end 51Q of the interference member 51 and abuts against the bill BL by the action of elastic force. At this time, since the tongue piece 43 is bent only in a relatively short range in the vicinity of the outer end portion 43A, the acting elastic force is relatively small. Further, the outer end portion 43A has a distance (so-called linear distance) from the rotation shaft 37 that is significantly shorter than the distance when the conventional dispensing portion 604 contacts the bill BL on the rotation locus 43R, and the rotation speed is also high. small.

Therefore, the dispensing unit 4 can suppress the noise generated when the outer end 43A of the tongue piece 43 collides with the bill BL significantly smaller than the conventional dispensing unit 604.

In this way, when the impeller 41 is rotated, the dispensing portion 4 can gradually bring the tongue piece 43 into contact with the interference member 51, and the outer end portion 43 A of the tongue piece 43 can be connected to the rotating shaft 37. Since it can be made to collide with the banknote BL in a state where the speed is lowered close to the noise, noise generated along with the collision can be extremely reduced.

By the way, when the banknote BL is not transported in the transport path 32, the dispensing unit 4 has an upper end when the outer end portion 43A of the tongue 43 is pulled away from the upper end 51Q of the interference member 51 as shown in FIG. 8A. The apex portion of 51Q slides with the outer surface of the tongue piece 43.

Here, as shown in FIG. 8B, it is assumed that the virtual withdrawal portion 104 is provided with an interference member 151 that is bent so that the upper end 151Q is inclined forward instead of the interference member 51. That is, the inner side surface of the interference member 151 in the vicinity of the upper end 151Q is inclined such that the normal line L3 is closer to the rotating shaft 37 than the tangent L4 of a virtual circle passing through the upper end 151Q.

In the dispensing portion 104, when the outer end portion 43A of the tongue piece 43 is separated from the upper end 151Q of the interference member 151, a relatively wide range including the vicinity of the outer end portion 43A slides only with the upper end 151Q. It will be squeezed by the tip. As a result, the withdrawal portion 104 may be worn or damaged on the tongue 43 in a relatively short period.

On the other hand, in the dispensing part 4 (FIG. 8A) according to the present embodiment, the inner side surface in the vicinity of the upper end 51Q of the interference member 51 is rotated more than the tangent L6 of a virtual circle whose normal line L5 passes through the upper end 51Q. It is tilted away from the shaft 37.

As a result, when the outer end portion 43A of the tongue 43 is pulled away from the upper end 51Q of the interference member 51, the dispensing portion 4 slides with the outer end portion 43A and the vicinity thereof in a relatively wide range including the vicinity of the upper end 51Q. It will be. Thereby, in the dispensing part 104, the possibility that the tongue 43 is worn or damaged is extremely low.

Furthermore, the withdrawal part 4 made the area of the interference member 51 extremely small, and kept it sufficiently smaller than the area of the bill BL. Thereby, for example, compared with the case where the interference members 51A to 51C are connected in the left-right direction and the area thereof is enlarged, the volume of noise generated when the tongue piece 43 abuts can be reduced, and the The frequency can be increased.

Generally, it is known as a sound propagation characteristic that if the frequency is high, it is difficult to wrap around because the straightness is high, and if the frequency is low, it is easy to wrap around because the straightness is low. For this reason, in general, in order to prevent the propagation of noise, it is only necessary to shield the linear travel path of the sound in the high sound range, but it is necessary to take complicated noise measures such as sealing the space in the low temperature range. It is said.

In this respect, since the dispensing unit 4 according to the present embodiment has a high frequency of noise, complicated measures such as sealing are not required. For example, by providing a simple openable cover, the noise can be transferred to the outside. Propagation can be effectively blocked.

According to the above configuration, the dispensing unit 4 according to the present embodiment is provided with the interference member 51 in the rotation locus 43R of the tongue 43 of the impeller 41 below the lower guide 34. Accordingly, when the dispensing unit 4 rotates the impeller 41, the tongue piece 43 is first gradually brought into contact with the vicinity of the lower end 51P of the interference member 51, and then the tongue piece 43 is slid on the interference member 51. Thereafter, the middle part 43B is first brought into contact with the banknote BL transported in the transport path 32, the outer part thereof is gradually brought into contact, and finally the outer end part 43A is slightly bent to form the banknote BL. Collide with. As a result, the dispensing portion 4 can suppress the noise generated with the collision between the outer end portion 43 A of the tongue piece 43 and the banknote BL to an extremely low level.

[5. Other Embodiments]
In the above-described embodiment, the case where the interference member 51 has a shape in which the lower portion of the thin plate-like member with the plate surface directed in the front-rear direction is bent slightly forward is described.

However, the present invention is not limited to this, and may have other various shapes. For example, the interference plate 251 shown in FIG. 9A may be a single thin plate without bending the plate surface in the front-rear direction, or it is generally curved like the interference member 351 shown in FIG. 9B. It may be a plate. In this case, the point is that the outer end 43A of the tongue piece 43 is gradually moved closer to the rotating shaft 37 side by being provided in the rotation locus 43R, and the outer guide 43 is relatively close to the lower guide 34. What is necessary is just to complete | finish sliding of the edge part 43A and to contact | abut to the banknote BL in the conveyance path 32. FIG.

In the above-described embodiment, the case where the lower end 51P of the interference member 51 is positioned outside the rotation locus 43R has been described.

However, the present invention is not limited to this, and the lower end 451P may be positioned inside the rotation locus 43R, for example, like an interference member 451 shown in FIG. 10A. In this case, by bringing the lower end 451P as close as possible to the rotation locus 43R, an effect similar to that obtained when the lower end 51P is positioned outside the rotation locus 43R like the interference member 51 can be obtained.

Furthermore, in the above-described embodiment, a case has been described in which the vicinity of the lower end 51P of the interference member 51 is an inclined surface in which the normal line L1 is inclined to the rotation axis 37 side with respect to the tangent line L2 of the rotation locus 43R. (FIG. 6A).

However, the present invention is not limited to this. For example, the vicinity of the lower end 51P of the interference member 51 is inclined so that the normal line L1 thereof is in the same direction as the tangent line L2 of the rotation locus 43R or opposite to the rotation shaft 37. Anyway.

Further, in the above-described embodiment, the case where the bent plate-like interference member 51 is provided in the rotation locus 43R of the tongue piece 43 in the impeller 41 has been described.

For example, as shown in FIG. 10B, a cylindrical interference member 551 having a central axis directed in the left-right direction is located near the lower guide 34 and within the rotation locus 43 R of the tongue piece 43. You may make it provide. In this case, it is desirable to suppress noise generated when the tongue piece 43 abuts by increasing the strength of the interference member 551.

When this interference member 551 is used, as in the case of using the interference member 51, the outer end portion 43A of the tongue piece 43 is slid in the vicinity of the lower guide 34, bent, and then brought into contact with the bill BL. Thereby, the noise generated when the outer end portion 43A collides with the bill BL can be suppressed to an extremely small level.

Furthermore, in the above-described embodiment, the case where the upper end 51Q (FIG. 4) of the interference member 51 is brought close to the lower guide 34 has been described.

However, the present invention is not limited to this. For example, the upper end 51Q may be moved away from the lower guide 34 to some extent, for example, the distance from the lower guide 34 to the upper end 51Q may be further away than the distance from the lower guide 34 to the rotating shaft 37. good.

Furthermore, in the above-described embodiment, the case where each interference member 51 (51A, 51B, and 51C) is configured by one member has been described.

However, the present invention is not limited to this, and each interference member 51 may be composed of a combination of two or more members. As a result, each component can be made smaller as compared with the case of being constituted by one member, so that the magnitude of noise generated when the tongue piece 43 abuts is further reduced, and the frequency band is reduced. It becomes possible to raise.

Furthermore, in the above-described embodiment, the case where one

interference member

51A or 51C is arranged with respect to the two impellers 41 arranged adjacent to each other outside the discharge roller 36 has been described (FIG. 5). ).

However, the present invention is not limited to this. For example, an interference member 51 having a short length in the left-right direction and corresponding to one impeller 41, that is, an interference member 51 having the same size as the interference member 51B is provided for each impeller 41. You may arrange | position so that it may correspond. Alternatively, on the contrary, the interference member 51 having a long length in the left-right direction and corresponding to three or more impellers 41 may be arranged.

Furthermore, in the above-described embodiment, the case where the interference member 51 is made of a metal material has been described.

However, the present invention is not limited to this, and the interference member 51 may be made of, for example, a resin material. In this case, it is desirable to suppress the occurrence of bending and vibration as much as possible by sufficiently increasing the strength.

Furthermore, in the above-described embodiment, the case where the interference member 51 is not particularly processed has been described.

However, the present invention is not limited to this, and the friction coefficient may be reduced, for example, by subjecting the surface of the interference member 51 to various types of processing such as polishing or plating. Or you may make it improve durability by performing the hardening process with respect to the interference member 51. FIG.

Further, in the above-described embodiment, the case where the interference member 51 is provided in the rotation locus 43R of the tongue piece 43 in the impeller 41 in the dispensing unit 4 that dispenses the banknote BL has been described.
