Description

The present invention relates to a currency processing device.

Conventionally, a coin processing machine has been known as a currency processing device that identifies coins transported by a transport belt and dispenses only coins of a single denomination in a predetermined number that has been designated in advance (see, for example, Patent Document 1).

Another known currency processing device is a banknote processing device that identifies banknotes transported by a transport unit and stores the identified banknotes in a banknote storage cassette so that they can be fed out (see, for example, Patent Document 2).

However, in the coin processing machine and banknote processing machine described above, when recovering from an error such as a jam, the conveyor belt or conveyor section is opened and the conveyor path is visually checked, which can lead to coins remaining in blind spots within the machine being overlooked, resulting in a miscount.

Therefore, a technical problem arises that needs to be solved in order to prevent coins in blind spots inside the aircraft from being overlooked, and the present invention aims to solve this problem.

In order to achieve the above object, the currency processing device of the present invention is a currency processing device comprising a fixed section, and an opening/closing section that is capable of opening and closing relative to the fixed section and allows an operator to access the fixed section when opened, and is also provided with a detection section capable of detecting the degree to which the opening/closing section opens relative to the fixed section, an illumination section that irradiates light into a blind spot area of the fixed section, and a control section that determines whether or not to irradiate the light depending on the opening degree of the opening/closing section, and irradiates the light at least when the opening degree of the opening/closing section is in a fully open state in which the opening/closing section is released from the fixed section.

With this configuration, the lighting unit shines light toward the blind spot area depending on the degree to which the opening/closing unit is open relative to the fixed unit, improving visibility of the blind spot area during recovery operations for errors such as jams, and reducing the risk of coins being overlooked.

The present invention improves the visibility of blind spots when recovering from errors such as jams, and can prevent coins from being overlooked.

FIG.

First Embodiment
A coin processing machine 10 according to a first embodiment of the present invention will be described with reference to the drawings. Note that, hereinafter, when the number, value, amount, range, etc. of components are mentioned, unless otherwise specified or when it is clearly limited to a specific number in principle, the number is not limited to the specific number, and may be more or less than the specific number.

In addition, when referring to the shape or positional relationship of components, etc., this includes things that are substantially similar or similar to that shape, etc., unless otherwise specified or considered in principle to be clearly different.

In addition, drawings may exaggerate characteristic parts to make the features easier to understand, and the dimensional ratios of components may not necessarily be the same as in reality.

As shown in FIG. 1, the coin processing machine 10 is provided with a coin insertion section 11 into which an operator inserts loose coins, and below the coin insertion section 11 is provided a payout mechanism 12 that pays out the loose coins inserted into the coin insertion section 11 one by one.

The payout mechanism 12 includes a rotating disk 13 that receives loose coins inserted into the coin insertion section 11 and is rotatable around a vertical axis, a separation section 14 that is located to the side of the rotating disk 13 and separates and pays out coins one by one by passing coins that move outward due to the centrifugal force generated by the rotation of the rotating disk 13, and a payout motor (not shown) that drives the rotating disk 13.

A coin passage 18 is arranged horizontally to the side of the separation section 14, and guides the coins dispensed from the separation section 14 on a passage surface 17 between the higher guide walls 15, 16 on both sides. The distance between the guide walls 15, 16, i.e., the width of the passage surface 17, is set to a width that allows the coins dispensed from the dispensing mechanism 12 to be arranged and transported in the order in which they were dispensed.

The coin passage 18 has a first straight portion 18a connected to the separation portion 14 and extending in a direction approximately tangential to the rotating disk 13, a second straight portion 18b extending from the opposite side of the first straight portion 18a to the separation portion 14 in a direction approximately perpendicular to the first straight portion 18a, and a third straight portion 18c extending from the opposite side of the second straight portion 18b to the first straight portion 18a in a direction approximately perpendicular to the second straight portion 18b.

Above the coin passage 18, a conveying mechanism 19 is provided that conveys coins dispensed from the payout mechanism 12 into the coin passage 18 along the coin passage 18 while pressing them from above. The conveying mechanism 19 includes an inlet belt 20 that is linear in plan view and conveys coins dispensed from the rotating disk 13 on the upstream side of the first straight section 18a, an upstream conveying belt 21 that is U-shaped in plan view and conveys coins sent out from the inlet belt 20 in the order of the first straight section 18a, the second straight section 18b, and a part of the second straight section 18b side of the third straight section 18c, and a downstream conveying belt 22 that is linear in plan view and receives coins from the upstream conveying belt 21 and conveys them on the remaining part of the third straight section 18c opposite the second straight section 18b.

The introduction side belt 20 is an endless belt made of a high-friction material having elasticity such as rubber, and both ends are held by a pair of pulleys 23, 24. The downstream pulley 24 is fixed to the drive shaft 26 of the introduction side drive motor 25, and the introduction side belt 20 is driven and rotated by the introduction side drive motor 25. The upstream pulley 23 may also be fixed to the drive shaft 26 of the introduction side drive motor 25.

The upstream conveyor belt 21 is an endless belt made of a high-friction elastic material such as rubber, and both ends are held by a pair of pulleys 27, 28, and two bent portions are held by upper and lower pulleys 29, 30, respectively.

Like the upstream conveyor belt 21, the downstream conveyor belt 22 is also an endless belt made of a high friction material, and both ends are held by a pair of pulleys 31, 32. The downstream pulley 28 of the upstream conveyor belt 21 and the upstream pulley 31 of the downstream conveyor belt 22 are fixed coaxially. The downstream pulley 32 is fixed to the drive shaft 34 of the conveyor drive motor 33, and the upstream conveyor belt 21 and the downstream conveyor belt 22 are driven by the conveyor drive motor 33 to rotate synchronously. Any of the other pulleys 27, 28, 31 may be fixed to the drive shaft 34 of the conveyor drive motor 33.

In this way, the conveying mechanism 19 is made up of the introduction belt 20, the upstream conveying belt 21, and the downstream conveying belt 22, as well as the pulleys 23 and 24, the introduction drive motor 25, pulleys 27 to 32, and the conveying drive motor 33.

The payout mechanism 12, the coin passage 18 and the transport mechanism 19 constitute the payout transport section 35, which separates and pays out and transports the coins inserted into the coin insertion section 11 one by one.

A coin detection sensor 36 and a coin identification section 37 are provided on the passage surface 17 of the first straight section 18a. The coin detection sensor 36 is provided near the payout mechanism 12 at a position on the inlet side belt 20 in the conveying direction, and detects the passage of coins moving on the passage surface 17. The coin detection sensor 36 is, for example, an optical sensor, and serves as a count sensor that can count the number of coins passing by detecting the passage of coins moving on the passage surface 17.

The coin identification unit 37 is provided at the position of the upstream conveyor belt 21 in the conveying direction of the first straight section 18a, and includes a CCD camera or the like that detects the image (or material) of the coins conveyed by the upstream conveyor belt 21 through the coin passage 18, thereby identifying whether the coins are genuine or counterfeit, and identifying the denomination of the coins, and counting them.

In the second straight section 18b, at the position of the upstream conveyor belt 21 in the conveying direction, an upstream coin sorting section 38 is provided which sorts coins conveyed through the coin passage 18 by the upstream conveyor belt 21 based on the recognition results of the coin recognition section 37, etc. The upstream coin sorting section 38 includes a removal and sorting section 39 and a reject sorting section 40 located downstream of the removal and sorting section 39.

The removal/sorting unit 39, when executing a counting mode in which a specified number of coins of a single denomination are counted and removed, removes up to the specified number of coins of the single denomination being counted from the coin passage 18, and does not remove coins from the coin passage 18 when executing a storage mode in which mixed denomination coins are counted, sorted by denomination, and stored.

The removal/sorting section 39 includes a sorting hole 39a formed to penetrate the passage surface 17, a shutter 39b that opens and closes the sorting hole 39a, and a solenoid 39c that drives the shutter 39b to open and close. When the shutter 39b is opened, coins are dropped from the sorting hole 39a. The sorting hole 39a is connected via a chute (not shown) to an unillustrated removal port located at a position facing the outside of the machine, and guides the dropped coins to the removal port so that they can be removed from the machine.

The reject sorting unit 40 removes from the coin passage 18 coins other than those to be counted, including unidentifiable coins, and coins of the denomination to be counted that exceed the specified number when the counting mode is executed, and also removes from the coin passage 18 unidentifiable coins when the storage mode is executed.

The reject sorting section 40 includes a sorting hole 40a formed to penetrate the passage surface 17 of the coin passage 18, a shutter 40b that opens and closes the sorting hole 40a, and a solenoid 40c that drives the shutter 40b to open and close. When the shutter 40b is opened, coins are dropped from the sorting hole 40a. The sorting hole 40a is connected via a chute (not shown) to a reject port provided at a position facing the outside of the machine, and guides the dropped coins to the reject port so that they can be removed from the machine.

A coin detection sensor 41 that detects coins is provided on the passage surface 17 of the second straight section 18b at a position upstream of the removal and sorting section 39. The coin detection sensor 41 is, for example, an optical sensor, and measures the timing of driving the solenoid 39c when dropping a detected coin. Furthermore, the coin detection sensor 41 can count the number of coins passing by detecting the passage of coins moving on the passage surface 17 due to the drive of the upstream conveyor belt 21.

A coin detection sensor 42 that detects coins is provided on the passage surface 17 of the second straight section 18b between the removal and sorting section 39 and the reject sorting section 40. The coin detection sensor 42 is, for example, an optical sensor, and measures the timing of driving the solenoid 40c when dropping a detected coin. Furthermore, the coin detection sensor 42 can count the number of coins passing by detecting the passage of coins moving on the passage surface 17 due to the drive of the upstream conveyor belt 21. In other words, the coin detection sensor 42 can count coins between the removal and sorting section 39 and the reject sorting section 40.

The third straight section 18c is provided with a denomination sorting section 43 that, in the storage mode, sorts the coins identified by the coin identification section 37 by denomination. The denomination sorting section 43 has sorting holes 44a to 44f, the same number as the number of denominations, through which the coins transported by the upstream conveyor belt 21 and the downstream conveyor belt 22 are sorted by denomination and dropped.

The sorting holes 44a to 44f are arranged so that coins fall in order of smallest diameter. That is, the smallest sorting hole 44a drops 1 yen coins, the wider sorting hole 44b drops 50 yen coins, the wider sorting hole 44c drops 5 yen coins, the wider sorting hole 44d drops 100 yen coins, the wider sorting hole 44e drops 10 yen coins, and the wider sorting hole 44f drops 500 yen coins. The coins sorted through the sorting holes 44a to 44f are stored by denomination in a storage unit not shown. Coin detection sensors 45a to 45f are positioned immediately before each of the sorting holes 44a to 44f, and the difference in the number of coins that pass through each of the adjacent coin detection sensors is counted as the number of coins that have been sorted into the sorting holes 44a to 44f located between them.

The operation of the coin processing machine 10 is controlled via the control unit 46. The control unit 46 controls each of the components that make up the coin processing machine 10.

When an error such as a jam occurs, the operator opens the transport mechanism 19 as an opening/closing part and visually checks whether there are any coins remaining in the coin passage 18 as a fixed part, but there is a risk that coins remaining in the blind spot area BS inside the coin processing machine 10 may be overlooked. Here, the "fixed part" refers to a component that serves as a reference when the opening/closing part is opened and closed, and does not mean that its position is absolutely fixed. Also, the "blind spot area BS" refers to an area that is difficult for the operator to visually check because it is hidden in the shadow of the opening/closing part, etc.

Figure 2 shows a state in which the downstream conveyor belt 22 is lifted up around the drive shaft 34 of the conveyor drive motor 33, allowing the operator to access the third straight section 18c. In Figure 2, the area around the sorting hole 44f, which is shaded because there is not enough space between the third straight section 18c and the fully open downstream conveyor belt 22, corresponds to the "blind spot area BS."

To prevent coins from being overlooked in the blind spot area BS described above, as shown in FIG. 1, the coin processing machine 10 is equipped with a detection unit 47 capable of detecting the opening degree of the downstream conveyor belt 22 relative to the third straight portion 18c, and an illumination unit 48 that irradiates light toward the blind spot area BS.

The detection unit 47 detects the opening angle of the downstream conveyor belt 22 relative to the third straight portion 18c. The detection unit 47 may be, for example, a photointerrupter attached to the downstream conveyor belt 22 to measure the opening angle, or a proximity sensor attached to the cover of the coin processing machine 10 to detect that the downstream conveyor belt 22 has opened.

The opening degree detected by the detection unit 47 is not limited to two stages, open and closed. For example, it is preferable to set it to three stages. The three stages of opening degree are divided into three stages, namely, a closed state in which the downstream conveyor belt 22 overlaps the third straight portion 18c and is closed, a fully open state in which the downstream conveyor belt 22 is released from the third straight portion 18c, and an open state from the closed state to the fully open state, as shown in FIG. 2. Note that the "fully open state" means a state in which the downstream conveyor belt 22 is released from the third straight portion 18c to an extent that the visibility of the blind spot area BS can be ensured, and means, for example, when the opening angle formed by the third straight portion 18c and the downstream conveyor belt 22 is greater than about 70 degrees when viewed from the side, or when a mechanism exists for locking the downstream conveyor belt 22 that has been opened to a predetermined opening angle so that it does not close under its own weight, the locking mechanism is activated.

The lighting unit 48 is preferably, but not limited to, a surface-emitting light source such as an LED chip or a COB (Chip On Board) LED. The lighting unit 48 is disposed, for example, at the bottom of the rotating disk 13, but may be disposed in any location that can irradiate the blind spot area BS with light. In addition, the lighting unit 48 is preferably equipped with a rotation mechanism or swing mechanism that can adjust the direction in order to adjust the range of light irradiation.

In addition, it is preferable that the lighting unit 48 is detachably attached to the coin processing machine 10, for example, by a magnet or a hook-and-loop fastener. This makes it possible to reduce the number of lighting units 48 installed by providing a removable lighting unit 48 near any blind spot area BS, instead of providing fixed lighting units 48 near all blind spot areas BS within the coin processing machine 10. In addition, the removable lighting unit 48 can also be used as a handy light to illuminate the blind spot area BS by leaving it constantly lit when detached.

The control unit 46 determines whether to irradiate different types of light or not to irradiate light depending on the degree of opening detected by the detection unit 47, that is, the closed state, the open state, or the fully open state. Here, the "light mode" refers to the color of light irradiated by the illumination unit 48 or the light emission time when the illumination unit 48 turns on or blinks the light, etc.

It is preferable that the control unit 46 emits light with the highest visibility when the opening degree is in the fully open state. For example, the control unit 46 controls the light of the illumination unit 48 to be on when the light is fully open, to blink or off when the light is open, and to be off when the light is closed. Alternatively, the control unit 46 may control the light color of the illumination unit 48 to be a highly visible color with high brightness such as white when the light is fully open, a low brightness warning color such as red or orange when the light is open, and to be off when the light is closed. In this way, by emitting light with different modes or switching off the light in the closed state, open state, and fully open state, the operator can grasp the opening degree of the downstream conveyor belt 22.

In this way, the coin processing machine 10 according to this embodiment is a coin processing machine 10 that includes a third straight section 18c, and a downstream conveying belt 22 that is arranged to be openable and closable relative to the third straight section 18c and that allows an operator to access the third straight section 18c when opened, and is configured to include a detection unit 47 that can detect the opening degree of the downstream conveying belt 22 relative to the third straight section 18c, an illumination unit 48 that irradiates light onto the blind spot area BS of the third straight section 18c, and a control unit 46 that determines whether or not to irradiate light depending on the opening degree of the downstream conveying belt 22, and irradiates light at least when the opening degree of the downstream conveying belt 22 is fully open.

With this configuration, the lighting unit 48 emits light toward the blind spot area BS according to the opening degree of the downstream conveying belt 22 relative to the third straight section 18c, thereby improving the visibility of the blind spot area BS during recovery operations for errors such as jams, and reducing the risk of coins being overlooked.

The coin processing machine 10 is divided into a fully open state, a closed state in which the downstream conveyor belt 22 is closed to the third straight section 18c, and an open state in which the closed state is changed to the fully open state, and the control unit 46 is configured to determine whether to irradiate light in a different manner or not to irradiate light at each opening degree of the closed state, open state, or fully open state.

With this configuration, the lighting unit 48 emits different types of light depending on the three levels of opening, or does not emit light, allowing the operator to grasp the opening level of the downstream conveying belt 22 and prompting the operator to open the downstream conveying belt 22 to the fully open state, so that recovery work can be performed with high visibility of the blind spot area BS, further reducing the risk of coins being overlooked.

The coin processing machine 10 is also configured so that the control unit 46 emits light with the highest visibility when the door is fully open.

This configuration improves visibility of the blind spot area BS of the third straight section 18c during recovery work, further reducing the risk of coins being overlooked.

<Second embodiment>

Next, a banknote processing machine 50 according to a second embodiment of the present invention will be described with reference to the drawings. The banknote processing machine 50 of this embodiment performs deposit and withdrawal processing of banknotes. In the following, loose banknotes will be simply referred to as banknotes, and banknotes bundled together in a predetermined bundling unit (100 sheets) will be referred to as a banknote bundle.

As shown in FIG. 3, the banknote processing machine 50 of this embodiment has a deposit port 52 and a withdrawal port 53 at the top of the front side of the machine body 51. The withdrawal port 53 is provided above the deposit port 52.

The deposit port 52 has a shutter (not shown) that can be opened and closed; when the shutter is open, banknotes are inserted from outside the machine, and then the shutter is closed to feed the banknotes into the machine. When viewed from the front side of the machine, banknotes are stacked and placed from bottom to top with their length aligned in the left-right direction, and a deposit and feed unit 54 is provided at the bottom, which separates the banknotes stacked on the deposit port 52 one by one, starting from the bottom, and feeds them into the machine at specified intervals. Banknotes are basically transported inside the banknote processing machine 50 with their short sides aligned in the transport direction.

The deposit/feed unit 54, which feeds out banknotes from the deposit port 52, is equipped with a kick-out roller 54a that contacts the middle part of the short side of the bottommost banknote among the banknotes accumulated in the deposit port 52 and kicks it out to the inside of the machine, a feed roller 54b that feeds the banknotes kicked out by the kick-out roller 54a into the machine, and a separation roller 54c that stops relative to the feed roller 54b and separates the banknotes fed into the machine by the feed roller 54b one by one. Immediately after the deposit/feed unit 54, an entrance sensor 55 is provided to optically detect whether the banknotes fed from the deposit/feed unit 54 have any transport abnormalities such as multiple stacked feeds, slanted feeds in a diagonal position relative to the transport direction, or near feeds where the transport interval between adjacent banknotes is narrow, and whether there are any shape abnormalities such as stubs.

The withdrawal port 53 has a shutter (not shown) that can be opened and closed; when the shutter is closed, banknotes to be withdrawn are dispensed from the machine, and then the shutter is opened to remove the banknotes from the machine. In other words, the withdrawal port 53 allows banknotes to be removed from the machine. The withdrawal port 53 stacks and places banknotes dispensed from the machine, stacked from bottom to top, with their length aligned in the left-right direction when viewed from the front side of the machine. When the shutter is closed, the withdrawal port 53 is capable of storing banknotes, and the stored banknotes can be dispensed into the machine.

At the rear of the banknote processing machine 50, there is provided an identification unit 56 that identifies the authenticity of banknotes dispensed from the deposit port 52, the denomination of the authentic banknotes, and the presence or absence of transport abnormalities such as double feeding, skewing, or near feeding. The identification unit 56 also identifies the front and back, top and bottom (top and bottom), left and right, etc. of the banknotes.

Behind the deposit port 52 and the withdrawal port 53, there are provided a number of alignment sections 57, 58, specifically two alignment sections 57, 58, which align the banknotes and stack them in a predetermined bundling unit. Behind these alignment sections 57, 58, there is provided a lifting and transporting section 59, which transports upward the number of bundling unit banknotes accumulated in the alignment sections 57, 58. Above the alignment sections 57, 58, there is provided a bundling section 60, which wraps bundling tape around the number of bundling unit banknotes accumulated in the alignment sections 57, 58 and transported by the lifting and transporting section 59 to form a bundle of banknotes.

A bundle dispensing unit 61 is provided in front of the bundling unit 60, which dispenses the bundle of banknotes created by the bundling unit 60 so that it can be removed outside the machine. The bundle dispensing unit 61 also has an openable and closable shutter (not shown), and the bundle of banknotes is dispensed from the machine when the shutter is closed, and then the bundle of banknotes is removed outside the machine by opening the shutter. A bundle storage unit (not shown) is provided to the side of the bundling unit 60, which stores the bundle of banknotes bound by the bundling unit 60.

In the lower part of the banknote processing machine 50, multiple storage cabinets 62, specifically four, of similar structure are arranged front to back, aligned vertically and horizontally. These storage cabinets 62 are capable of temporarily storing banknotes and dispensing temporarily stored banknotes, and are capable of storing banknotes and dispensing stored banknotes. These storage cabinets 62 cannot be removed from the machine body 51, but can be pulled out from the machine body 51 as a unit.

In the banknote processing machine 50, the storage cabinet 62A located at the very back, the storage cabinet 62B located second from the back, and the storage cabinet 62C located third from the back all store undamaged banknotes of a specific denomination in a state where they can be dispensed after being stacked from bottom to top. The storage cabinet 62D located fourth from the back stores other specific banknotes in a state where they can be dispensed after being stacked from bottom to top.

Among acceptable banknotes that can be received by the banknote processing machine 50, the storage 62A stores predetermined first-type banknotes (for example, current 10,000 yen notes that are undamaged and normal banknotes), the storage 62B stores predetermined second-type banknotes (for example, current 5,000 yen notes that are undamaged and normal banknotes), the storage 62C stores predetermined third-type banknotes (for example, current 1,000 yen notes that are undamaged and normal banknotes), and the storage 62D stores fourth-type banknotes other than the first to third types (for example, all 2,000 yen notes, current 10,000 yen notes that are soiled and damaged, all old 10,000 yen notes, current 5,000 yen notes that are soiled and damaged, all old 5,000 yen notes, current 1,000 yen notes that are soiled and damaged, and all old 1,000 yen notes), each of which can be dispensed. In other words, the banknote processing machine 50 has multiple storage bins 62A to 62C for current undamaged normal banknotes of a single denomination, by denomination. Note that as long as multiple storage boxes 62 are provided so that banknotes can be sorted and stored, the storage pattern is not limited to the above.

At the top of each of storage boxes 62A-62D, there is provided an intake/feed-out section 63 that takes in banknotes and stacks them from bottom to top, while also separating the banknotes one by one from the top and feeding them out at specified intervals. Each of storage boxes 62A-62D is provided with a separator 64 (bottom) that can be raised and lowered and opened and closed to divide the internal space that holds the banknotes into upper and lower parts, and an elevator 65 that moves up and down within the internal space.

The take-in/pay-out unit 63 includes a kick-out roller 63a that contacts the middle part of the short side of the topmost banknote among the banknotes stacked on the separator 64 or the elevator 65 and kicks it out of the storage 62, a pay-out roller 63b that pays out the banknotes kicked out by the kick-out roller 63a out of the storage 62, and a separation roller 63c that stops relative to the pay-out roller 63b and separates the banknotes that the pay-out roller 63b pays out of the storage 62 one by one. The pay-out roller 63b rotates in the opposite direction to when it is paid out, and holds the banknotes between itself and the separation roller 63c that rotates with it, and takes them into the storage 62.

The separator 64 comprises a pair of lifting shafts 64a arranged horizontally at the same height, and a pair of plate-shaped separator bodies 64b. One separator body 64b is supported by one lifting shaft 64a and can rotate around this lifting shaft 64a. The other separator body 64b is supported by the other lifting shaft 64a and can rotate around this lifting shaft 64a. When the separator 64 is in a closed state, one separator body 64b extends horizontally from one lifting shaft 64a toward the other lifting shaft 64a, and the other separator body 64b extends horizontally from the other lifting shaft 64a toward one lifting shaft 64a.

When the separator 64 is in the open state, one separator body 64b rotates 90 degrees from the closed state and extends vertically downward from one lifting support shaft 64a, and the other separator body 64b rotates 90 degrees from the closed state and extends vertically downward from the other lifting support shaft 64a. The pair of lifting support shafts 64a of the separator 64 always rise and fall to the same height, and the pair of separator bodies 64b open and close in sync. Each separator 64 in the storage units 62A to 64D is driven by an individual drive mechanism, and the rise and fall and opening and closing are controlled independently.

When the separator 64 is in a closed state, it divides the storage 62 in which it is provided into a temporary storage section 66 above the separator 64, including the separator 64, and a storage section 67 below the separator 64. In other words, the storage 62 is divided by the separator 64 into the temporary storage section 66, which is a temporary storage area, and the storage section 67, which is a storage area directly below it.

When the separator 64 is in the closed state, it forms the bottom of the temporary storage section 66, on which the banknotes taken in by the intake and feed section 63 are placed and stacked from bottom to top. At that time, the separator 64 descends according to the amount of banknotes taken in by the intake and feed section 63. The separator 64 also raises the topmost banknote among the banknotes placed thereon and brings it into contact with the kick-out roller 63a of the intake and feed section 63. In this state, the intake and feed section 63 separates the banknotes one by one and feeds them out of the temporary storage section 66. At that time, the separator 64 rises according to the amount of banknotes fed out by the intake and feed section 63.

When the separator 64 is in the open state, the temporary storage section 66 and the storage section 67 of the storage 62 in which the separator 64 is installed are connected. In this state, the elevator 65 places the banknotes taken in by the take-in and pay-out section 63 and accumulates them from bottom to top. At that time, the elevator 65 first rises to a receiving position where it accepts the banknotes taken in by the take-in and pay-out section 63 above it or on top of the banknotes above it, and then descends according to the amount of banknotes taken in by the take-in and pay-out section 63.

Therefore, when the separator 64 is in the open state, the storage 62A receives the banknotes taken in by the take-in/feed-out unit 63 into the successive temporary storage unit 66 and storage unit 67, and accumulates them in the temporary storage unit 66 on the elevator 65. After that, when the elevator 65 descends and the banknotes on the elevator 65 reach the storage unit 67 and the separator 64 is closed, the storage 62A enters a state in which the storage unit 67 stores the banknotes.

Similarly, when the separator 64 is in the open state, the storage vault 62B receives the banknotes taken in by the take-in/feed-out unit 63 into the successive temporary storage unit 66 and storage unit 67, and accumulates them in the temporary storage unit 66 on the elevator 65. After that, when the elevator 65 descends and the banknotes on the elevator 65 reach the storage unit 67 and the separator 64 is closed, the storage vault 62B enters a state in which the storage unit 67 stores the banknotes.

Similarly, when the separator 64 is in the open state, the storage vault 62C receives the banknotes taken in by the take-in/feed-out unit 63 into the successive temporary storage unit 66 and storage unit 67, and accumulates them in the temporary storage unit 66 on the elevator 65. After that, when the elevator 65 descends and the banknotes on the elevator 65 reach the storage unit 67 and the separator 64 is closed, the storage vault 62C enters a state in which the storage unit 67 stores the banknotes.

Similarly, when the separator 64 is in the open state, the storage vault 62D receives the banknotes taken in by the take-in/feed-out unit 63 into the successive temporary storage unit 66 and storage unit 67, and accumulates them in the temporary storage unit 66 on the elevator 65. After that, when the elevator 65 descends and the banknotes on the elevator 65 reach the storage unit 67 and the separator 64 is closed, the storage vault 62D enters a state in which the storage unit 67 stores the banknotes.

When the separator 64 is in the open state and the temporary storage section 66 and storage section 67 of the storage 62 in which the separator 64 is provided are connected, and the elevator 65 of the storage section 67 rises, the elevator 65 brings the topmost banknote among the banknotes placed on it into contact with the kick-out roller 14a of the take-in and pay-out section 63. In this state, the take-in and pay-out section 63 separates the banknotes one by one and pays them out from the continuous temporary storage section 66 and storage section 67 to the temporary storage section 66. At that time, the elevator 65 rises according to the amount of banknotes paid out from the take-in and pay-out section 63. The elevators 65 of the storage 62A to 62D are each driven by an individual drive mechanism, and their elevation is controlled independently.

The standby state of each of storage vaults 62A to 62D is when the elevator 65 is located in the lowest standby position, the banknotes on the elevator 65 are located below the separator 64, the separator 64 is closed, and the separator 64 is located in a predetermined standby position at the top, so that banknotes taken in by the take-in/feed-out unit 63 can start to be accumulated on the separator 64. Therefore, when each of storage vaults 62A to 62D is in the standby state, the temporary storage unit 66 is empty. The standby state of storage vaults 62A to 62D is a storage receiving state in which stored banknotes are received into the temporary storage unit 66.

In addition, each of the multiple storage units 62A to 62D is in a stored banknote payout state in which the banknotes placed on the separator 64 of the temporary storage unit 66 are paid out when the elevator 65 is positioned in the lowest standby position, the separator 64 is closed, and the banknote in the uppermost position on the separator 64 is brought into contact with the kick-out roller 63a of the take-in and pay-out unit 63.

In addition, the multiple storage vaults 62A to 62D each open the separator 64 and accumulate the banknotes taken in by the take-in/feed-out unit 63 on the elevator 65 or on top of the topmost banknote on the elevator 65, which is a direct storage receiving state in which banknotes are received in the continuous temporary storage unit 66 and storage unit 67. After each of the multiple storage vaults 62A to 62D receives banknotes on the elevator 65 with the separator 64 in the open state, the elevator 65 is lowered, and when all the banknotes on the elevator 65 are located below the open separator 64, the separator 64 is closed. In this state, the banknotes are stored in the storage unit 67. The storage unit 67 of each of the multiple storage vaults 62A to 62D receives and stores banknotes via the temporary storage unit 66 above, with the separator 64 in the open state.

In addition, each of the multiple storage boxes 62A to 62D is in a storage/acceptance state in which banknotes that have been stored on the separator 64 of the temporary storage section 66 and are dropped when the separator 64 is opened can be accumulated on the elevator 65 or on top of the topmost banknote on the elevator 65, and the banknotes placed on the separator 64 of the temporary storage section 66 can be received on the elevator 65 of the storage section 67.

In addition, each of the multiple storage boxes 62A to 62D is in a stored banknote payout state in which the banknotes stored in the storage section 67 are paid out via the temporary storage section 66 when the separator 64 is open and the topmost banknote on the elevator 65 is brought into contact with the kick-out roller 63a of the take-in and pay-out section 63.

As described above, a temporary storage section 66 is provided above each storage section 67 of the multiple storage boxes 62A to 62D, in which the separator 64 at the bottom can be opened and closed and which temporarily stores banknotes so that they can be dispensed. Also, each storage section 67 of the multiple storage boxes 62A to 62D receives and stores banknotes via the upper temporary storage section 66 with the separator 64 in an open state. In other words, each storage section 67 of the multiple storage boxes 62A to 62D receives and stores banknotes via the upper temporary storage section 66 with the separator 64 at the bottom in an open state.

The storage vaults 62A-62D can be pulled out sideways from the machine body 51 as a unit, and the temporary storage section 66 can be opened and closed when pulled out as a unit from the machine body 51. When the temporary storage section 66 of each of the storage vaults 62A-62D is opened, the banknotes temporarily stored in the temporary storage section 66 can be removed to the outside. Note that, even if the temporary storage section 66 of each of the storage vaults 62A-62D is opened, if the separator 64 is closed, the banknotes stored in the storage section 67 below the separator 64 cannot be removed from the temporary storage section 66 side.

At the bottom of the banknote processing machine 50, in front of the storage vault 62D, a cassette 68 is provided as a temporary bulk storage section that temporarily stores acceptable banknotes of mixed denominations that can be received by the banknote processing machine 50 during the deposit process. The cassette 68 is removable from the machine body 51 and takes in and stores banknotes dispensed from the denomination-specific storage section 67 during the recovery process, and during the replenishment process, replenishment banknotes are loaded outside the machine and the loaded banknotes are dispensed. The cassette 68 is aligned front to back with the denomination-specific storage vaults 62A to 62D, aligned up, down, left and right. The storage capacity of the cassette 68 for banknotes is larger than the storage capacity of each of the storage vaults 62A to 62D.

The cassette 68 temporarily stores bills in a mixed denomination stacked from bottom to top and stores the temporarily stored bills so that they can be dispensed later. At the top of the cassette 68, an intake/dispensing section 69 is provided which takes in bills and separates the bills one by one starting from the top one and dispenses them at specified intervals. The cassette 68 is provided with a separator 70 (bottom) which can be raised and lowered and opened and closed to divide the internal space that stores the bills into upper and lower parts, and an elevator 71 which moves up and down within the internal space.

The take-in/feed-out unit 69 includes a kick-out roller 69a that contacts the middle portion of the short side of the topmost banknote among the banknotes stacked on the separator 70 or the elevator 71 and kicks it out of the cassette 68, a feed-out roller 69b that feeds out of the cassette 68 the banknotes kicked out by the kick-out roller 69a, and a separation roller 69c that stops relative to the feed-out roller 69b and separates the banknotes that the feed-out roller 69b feeds out of the cassette 68 one by one. The feed-out roller 69b rotates in the opposite direction to when it is fed out, and holds the banknotes between itself and the separation roller 69c that rotates with it, and takes them into the cassette 68.

The separator 70 comprises a pair of lifting shafts 70a arranged horizontally at the same height, and a pair of plate-shaped separator bodies 70b. One separator body 70b is supported by one lifting shaft 70a and can rotate around this lifting shaft 70a. The other separator body 70b is supported by the other lifting shaft 70a and can rotate around this lifting shaft 70a. When the separator 70 is in a closed state, one separator body 70b extends horizontally from one lifting shaft 70a toward the other lifting shaft 70a, and the other separator body 70b extends horizontally from the other lifting shaft 70a toward one lifting shaft 70a.

When the separator 70 is in the open state, one separator body 70b rotates 90 degrees from the closed state and extends vertically downward from one lifting support shaft 70a, and the other separator body 70b rotates 90 degrees from the closed state and extends vertically downward from the other lifting support shaft 70a. The pair of lifting support shafts 70a of the separator 70 always rise and fall to the same height, and the pair of separator bodies 70b open and close synchronously. The separator 70 of the cassette 68 is driven by a drive mechanism separate from the separators 64 of the storage cabinets 62A-62D, and is independently controlled for rising and falling and opening and closing.

When the separator 70 is in the closed state, the cassette 68 is divided into a temporary storage section 72 above the separator 70, including the separator 70, and a storage section 73 below the separator 70. In other words, the cassette 68 is divided by the separator 70 into the temporary storage section 72, which is a temporary storage area, and the storage section 73, which is a storage area directly below it.

When the separator 70 is in the closed state, it forms the bottom of the temporary storage section 72, and the banknotes taken in by the intake and feed section 69 are placed on it, and are accumulated from bottom to top. At that time, the separator 70 descends according to the amount of banknotes taken in by the intake and feed section 69. The separator 70 also raises the topmost banknote among the banknotes placed on it, causing it to come into contact with the kick-out roller 69a of the intake and feed section 69. In this state, the intake and feed section 69 separates the banknotes one by one and feeds them out of the temporary storage section 72. At that time, the separator 70 rises according to the amount of banknotes fed by the intake and feed section 69.

When the separator 70 is in the open state, the temporary storage section 72 and the storage section 73 of the cassette 68 are connected. In this state, the elevator 71 places the banknotes taken in by the take-in and pay-out section 69 and accumulates them from bottom to top. At that time, the elevator 71 first rises to a receiving position where it accepts the banknotes taken in by the take-in and pay-out section 69 above it or on top of the banknotes above it, and then descends according to the amount of banknotes taken in by the take-in and pay-out section 69.

When the separator 70 is in the open state, the cassette 68 receives the banknotes taken in by the take-in/feed-out unit 69 into the successive temporary storage unit 72 and storage unit 73, and accumulates them in the temporary storage unit 72 on the elevator 71. After that, when the elevator 71 descends and the banknotes on the elevator 71 reach the storage unit 73 and the separator 70 is closed, the cassette 68 enters a state in which the storage unit 73 stores the banknotes.

When the separator 70 is in the open state and the temporary storage section 72 and the storage section 73 of the cassette 68 are connected, and the elevator 71 of the storage section 73 rises, the elevator 71 brings the topmost banknote among the banknotes placed on it into contact with the kick-out roller 69a of the take-in and pay-out section 69. In this state, the take-in and pay-out section 69 separates the banknotes one by one and pays them out from the connected temporary storage section 72 and storage section 73 to the temporary storage section 72. At that time, the elevator 71 rises according to the amount of banknotes paid out from the take-in and pay-out section 69. The elevator 71 of the cassette 68 is driven by a drive mechanism separate from the elevators 65 of the storage units 62A to 62D, and its elevation is controlled independently.

The cassette 68 is in a standby state when the elevator 71 is positioned in the lowest standby position, the banknotes on the elevator 71 are positioned below the separator 70, the separator 70 is closed, and the separator 70 is positioned in a predetermined standby position at the top, so that the banknotes taken in by the take-in/feed-out unit 69 can start to be accumulated on the separator 70. Therefore, when the cassette 68 is in a standby state, the temporary storage unit 72 is empty. The standby state of the cassette 68 is a storage receiving state in which stored banknotes are received into the temporary storage unit 72.

In addition, the cassette 68 is in a stored banknote payout state in which the banknotes placed on the separator 70 in the temporary storage section 72 are paid out when the elevator 71 is positioned in the lowest standby position, the separator 70 is closed, and the banknotes in the uppermost position on the separator 70 are brought into contact with the kick-out roller 69a of the take-in and pay-out section 69.

In addition, the cassette 68 opens the separator 70 and accumulates the banknotes taken in by the take-in/feed-out unit 69 on the elevator 71 or on the topmost banknote on the elevator 71, which is a direct storage receiving state in which the temporary storage unit 72 and storage unit 73 receive banknotes. After the cassette 68 receives banknotes on the elevator 71 with the separator 70 in the open state, it lowers the elevator 71 and closes the separator 70 when all the banknotes on the elevator 71 are located below the open separator 70. In this state, the banknotes are stored in the storage unit 73. Therefore, the storage unit 73 receives and stores banknotes through the temporary storage unit 72 with the separator 70 at the top, which is the bottom, in the open state.

When the separator 70 of the cassette 68 is open and the topmost banknote on the elevator 71 is brought into contact with the kick-out roller 69a of the take-in and pay-out section 69, the cassette 68 is in a stored banknote pay-out state in which the banknotes stored in the storage section 73 are paid out via the temporary storage section 72.

As described above, above the storage section 73 of the cassette 68, a temporary storage section 72 is provided, in which the separator 70, which is the bottom, can be opened and closed and temporarily stores banknotes so that they can be fed out. In addition, the cassette 68 stores banknotes taken in by the take-in and feed-out section 69 in the storage section 73 below the separator 70 through the temporary storage section 72 with the separator 70 in an open state. In other words, below the separator 70, which is the bottom of the temporary storage section 72, a storage section 73 is provided, which receives and stores banknotes through the temporary storage section 72 when the separator 70 is in an open state.

Inside the banknote processing machine 50, a transport unit 74 that transports banknotes, including banknotes dispensed from the deposit port 52 by the deposit and dispensing unit 54, is provided to appropriately connect each unit. The transport unit 74 basically moves the banknotes with their short edges aligned along the transport direction.

The transport unit 74 transports banknotes from the deposit port 52 provided at the front of the machine body 51 toward the recognition unit 56 provided at the rear of the machine body 51, and further includes a transport path 74A that transports the banknotes toward the cassette 68 provided at the front of the machine body 51. The transport path 74A extends rearward from the deposit/payout unit 54 of the deposit port 52 to between the transport paths 74J and 74M described below, then extends downward, then extends rearward and passes through the recognition unit 56, turns forward at the bottom, extends forward, extends downward from the front end of the banknote processing machine 50, and connects to the intake/payout unit 69 of the cassette 68.

The conveying section 74 also includes a conveying path 74C that branches downward between the connection position of the conveying path 74A to the cassette 68 and the identification section 56, and leads to the intake and feed section 63 of the storage cabinet 62A; a conveying path 74D that branches downward between the connection position of the conveying path 74A to the cassette 68 and the branching position of the conveying path 74C, and leads to the intake and feed section 63 of the storage cabinet 62B; a conveying path 74E that branches downward between the connection position of the conveying path 74A to the cassette 68 and the branching position of the conveying path 74D, and leads to the intake and feed section 63 of the storage cabinet 62C; and a conveying path 74F that branches downward between the connection position of the conveying path 74A to the cassette 68 and the branching position of the conveying path 74E, and leads to the intake and feed section 63 of the storage cabinet 62D.

The transport section 74 also includes a transport path 74G that branches upward from the closest position to the cassette 68 on the transport path 74A, then extends rearward and connects to the lower portion of the portion of the transport path 74A that extends downward from the inlet 52 toward the identification section 56; a transport path 74H that branches upward from a position between the branching position of the transport path 74F on the transport path 74A and the branching position of the transport path 74G and connects to a midpoint of the transport path 74G; and a transport path 74J that branches upward from a position between the connection position of the transport path 74H on the transport path 74G and the connection position of the rear transport path 74A, and connects to the connection position of the rear of the transport path 74G on the transport path 74A and the entrance sensor 55.

In addition, the transport section 74 has a transport path 74L that branches rearward between the connection position of the transport path 74J on the transport path 74A and the connection position of the rear part of the transport path 74G, then extends upward, and then extends forward to connect to the withdrawal port 53.

The transport unit 74 also includes a transport path 74M that branches upward from between the connection position of the rear of the transport path 74G on the transport path 74A and the recognition unit 56 and is connected to the intermediate position of the transport path 74L, and a transport path 74N that branches from between the branch position of the transport path 74M on the transport path 74A and the recognition unit 7 and is connected to the intermediate position of the transport path 74M. The transport path 74N is provided with a front/back reversing unit 75 that reverses the front/back of the banknote.

The transport section 74 also includes a transport path 74P that branches rearward from between the withdrawal port 4 and the junction of the transport path 74M on the transport path 74L and leads to the alignment section 57, and a transport path 74Q that branches rearward from between the junction of the transport path 74P on the transport path 74L and the junction of the transport path 74M and leads to the alignment section 58.

The recognition unit 56 recognizes the banknotes transported by the transport unit 74, and the storage units 62A-62D and cassettes 68 store the banknotes recognized by the recognition unit 56 in a manner that allows them to be dispensed based on the recognition results of the recognition unit 56.

The banknote processing machine 50 includes an operation display unit 76 that receives operation input from an operator and displays information to the operator, and a control unit 77 that controls each of the components that make up the banknote processing machine 50.

When an error such as a jam occurs, the operator opens the drawer unit 78 (opening/closing section) surrounded by a dashed line in Figure 3 from the body 51 (fixed section) to visually check whether there are any bills remaining in the body 51, but there is a risk that bills remaining in a blind spot BS occurring within the body 51 will be overlooked. Here, the "fixed section" refers to a component that serves as a reference when the opening/closing section is opened and closed, and does not mean that its position is absolutely fixed. Also, the "blind spot area BS" refers to an area within the body 51 that is difficult for the operator to visually check because it is hidden in the shadow, etc.

Figure 4 shows a state in which the drawer unit 78 is released from the machine body 51, allowing the operator to access the inside of the machine body 51. In Figure 4, the back side of the storage space S in which the drawer unit 78 can be stored within the machine body 51 corresponds to the "blind spot area BS."

To prevent banknotes from being overlooked in the blind spot BS described above, as shown in FIG. 3, the banknote processing machine 50 is equipped with a detection unit 79 capable of detecting the opening degree of the drawer unit 78 relative to the machine body 51, and an illumination unit 80 that irradiates light toward the blind spot area.

The detection unit 79 detects the degree to which the drawer unit 78 is pulled out relative to the machine body 51. The detection unit 79 may be, for example, a photointerrupter attached to the drawer unit 78 to measure the degree of opening, or a proximity sensor attached to the machine body 51 to detect when the drawer unit 78 is separated.

The degree of opening detected by the detection unit 79 is not limited to two stages, open and closed. For example, it is preferable to set it to three stages. The three stages of opening are divided into a closed state in which the drawer unit 78 is housed in the body 51, a fully open state in which the drawer unit 78 is open from the body 51, and an open state ranging from the closed state to the fully open state. Note that the "fully open state" means a state in which the drawer unit 78 is open from the body 51 to an extent that visibility of the blind spot area BS can be ensured, and does not necessarily mean only a state in which the entire drawer unit 78 is pulled out from the body 51.

The lighting unit 80 is preferably, for example, a surface-emitting light source such as an LED chip or a COB (Chip On Board) LED, but is not limited to these. In FIG. 4, the lighting unit 80 is disposed on the top surface at the rear of the storage space S, but it may be disposed in any location as long as it is capable of irradiating light into the blind spot area BS. In addition, the lighting unit 80 is preferably equipped with a rotation mechanism or swing mechanism that can adjust the direction in order to adjust the range of light irradiation.

In addition, it is preferable that the lighting unit 80 is detachably attached to the body 51, for example, by a magnet or a hook-and-loop fastener. This makes it possible to reduce the number of lighting units 80 installed by providing detachable lighting units 80 near any blind spot BS, instead of providing fixed lighting units 80 near all blind spot areas BS in the banknote processing machine 50. In addition, the detachable lighting unit 80 can also be used as a handy light to illuminate the blind spot areas BS by leaving it constantly lit when detached.

The control unit 77 determines whether to irradiate different types of light or not to irradiate light depending on the degree of opening detected by the detection unit 79, that is, the closed state, the open state, or the fully open state. Here, the "light mode" refers to the color of light irradiated by the illumination unit 80 or the light emission time when the illumination unit 80 turns on or blinks the light, etc.

It is preferable that the control unit 77 emits light with the highest visibility when the drawer unit 78 is fully open. For example, the control unit 77 controls the light of the illumination unit 80 to be on when the drawer unit 78 is fully open, to blink or off when the drawer unit 78 is open, and to be off when the drawer unit 78 is closed. Alternatively, the control unit 77 may control the light color of the illumination unit 80 to be a highly visible color such as white when the drawer unit 78 is fully open, a low-brightness warning color such as red or orange when the drawer unit 78 is open, and to be off when the drawer unit 78 is closed. In this way, the operator can grasp the opening degree of the drawer unit 78 by emitting light with different modes or by switching off the light when the drawer unit 78 is closed, open, and fully open.

In this way, the banknote processing machine 50 according to this embodiment is a banknote processing machine 50 including a body 51 and a drawer unit 78 that is openable and closable relative to the body 51 and that allows an operator to access the storage space S within the body 51 when opened, and is configured to include a detection unit 79 that can detect the degree to which the drawer unit 78 is pulled out relative to the body 51, an illumination unit 80 that irradiates light into a blind spot area BS of the storage space S, and a control unit 77 that determines whether or not to irradiate light depending on the degree to which the drawer unit 78 is opened, and irradiates light at least when the drawer unit 78 is fully open.

With this configuration, the lighting unit 80 emits light toward the blind spot BS depending on the opening degree of the drawer unit 78 relative to the body 51, improving the visibility of the blind spot BS when recovering from an error such as a jam, and reducing the risk of banknotes being overlooked.

The banknote processing machine 50 is divided into a fully open state, a closed state in which the drawer unit 78 is housed within the machine body 51, and an open state that extends from the closed state to the fully open state, and the control unit 77 is configured to determine whether to irradiate light in a different manner or not to irradiate light in each of the open degrees of the closed state, open state, and fully open state.

With this configuration, the lighting unit 80 emits different types of light or turns off depending on the three levels of opening, allowing the operator to grasp the opening level of the drawer unit 78 and prompting the operator to open the drawer unit 78 to the fully open state, so recovery work can be performed with high visibility of the blind spot area BS, further reducing the risk of overlooking banknotes.

The banknote processing machine 50 is also configured so that the control unit 77 emits light with the highest visibility when the door is fully open.

This configuration improves visibility of the blind spot area BS of the storage space S during recovery work, further reducing the risk of banknotes being overlooked.

The present invention can be modified in various ways other than those described above without departing from the spirit of the invention, and it goes without saying that the present invention extends to such modifications. Furthermore, the above-described embodiments may be combined with each other.
