Description

Coin processing device

[0001] The technology disclosed herein relates to a coin processing device.

[0002] Patent Document 1 describes a conventional coin processing device. This coin processing device includes a cover member that covers a coin receiving portion. The cover member has a first coin insertion portion and a second coin insertion portion. The first coin insertion portion is a portion where coins are inserted. The first coin insertion portion has a plurality of foreign matter removal holes. The foreign matter removal holes remove foreign matter that is inserted into the first coin insertion portion together with the coins. Coins after the foreign matter has been removed by the foreign matter removal holes are inserted into the second coin insertion portion. The coins inserted into the second coin insertion portion fall into the coin receiving portion.

[0003] Japanese Patent Application Laid-Open No. 2019-046128

[0004] In the conventional coin processing device, after an operator once inserts a large number of coins into the first coin insertion portion, the operator has to manually take out the coins from the first coin insertion portion in appropriate amounts and insert them into the second coin insertion portion. The conventional coin processing device is troublesome for the operator's insertion operation and has poor operability regarding coin insertion.

[0005] Also, in the conventional coin processing device, when an error such as coin jamming occurs while inserting coins into the coin receiving portion, the cover member may be rotated to open the coin receiving portion. At this time, if there are coins remaining in the first coin insertion portion that have not been inserted, the operator has to manually take out the coins from the first coin insertion portion before rotating the cover member.

[0006] Also, when the operator wants to take out the coins in the first coin insertion portion, such as when a coin is accidentally inserted into the first coin insertion portion, the operator has to manually take out the coins from the first coin insertion portion.

[0007] The conventional coin processing device is also troublesome for the operation of manually taking out coins from the first coin insertion portion and has poor operability regarding coin removal.

[0008] The technology disclosed herein improves the operability regarding coin insertion or removal of a coin processing device.

[0009] The technology disclosed herein relates to a coin processing device. The coin processing device comprises a tray on which coins are placed, and a device housing on which the tray is mounted, wherein the device housing has a first opening into which coins are inserted from the tray and which sends the inserted coins into the device, and a second opening into which coins are inserted from the tray and which is connected to an outlet opening to the outside of the device housing, wherein the device housing tilts the tray to drop coins from the tray into the first opening by rotatably supporting the tray at a position on a first axis, and the device housing also tilts the tray to drop coins from the tray into the second opening by rotatably supporting the tray at a position on a second axis different from the position on the first axis.

[0010] The tray can hold coins. The operator places the coins to be processed by the coin processing machine onto the tray. The tray can hold a large number of coins at once.

[0011] The device housing has a first opening. The first opening is for feeding coins into the device. The device housing rotatably supports a tray at the position of the first axis. When the operator tilts the tray, coins fall from the tray into the first opening. The operator can directly insert a large number of coins from the tray into the first opening. The coin processing device offers high operability in terms of coin insertion.

[0012] The device housing has a second opening. The second opening is connected to an outlet that opens to the outside of the device housing. Coins inserted into the second opening are not sent into the coin processing unit. The device housing rotatably supports a tray at the position of the second axis. If the operator tilts the tray, coins will fall from the tray into the second opening. The operator can directly insert a large number of coins from the tray into the second opening. For example, when removing coins on the tray due to an error, or when removing coins that have been mistakenly placed on the tray, the operator can send the coins from the tray through the second opening to the outlet. The coin processing unit also offers high operability in terms of coin retrieval.

[0013] Because the positions of the first axis and the second axis are different, the operator can clearly distinguish between inserting coins from the tray into the first opening and inserting coins from the tray into the second opening. The coin processing device can prevent errors such as accidentally dropping coins into the first opening or the second opening.

[0014] The device housing may also be configured to hold the tray in place so that it does not detach from the device housing.

[0015] When a large number of customers operate a coin processing machine, there is a risk of the tray being lost if it detaches from the machine. A design that prevents the tray from detaching from the machine housing can reduce the risk of tray loss.

[0016] Here, the device housing may have a mounting section onto which the tray is mounted from above. The operator can lift the edge of the tray mounted on the mounting section and tilt it.

[0017] The tray mounted on the mounting portion may be exposed upwards to the outside of the device housing. This makes it easier for the operator to place coins on the upward-exposed tray.

[0018] The first opening and the second opening may be positioned at the bottom of the mounting portion, facing upward and separated horizontally.

[0019] If the first opening and the second opening are separated horizontally, errors such as accidentally dropping a coin into the first opening or the second opening are suppressed.

[0020] The tray may have a first pin that is rotatably engaged with the device housing at the position of the first axis, and the tray may be lifted at its first end with the first pin engaged with the device housing at the position of the first axis, thereby causing coins to fall from the second end of the tray opposite to the first end into the first opening.

[0021] The operator can lift the first end of the tray, causing the numerous coins placed on the tray to fall sequentially from the second end of the tray into the first opening. This makes it easy for the operator to insert the coins into the first opening.

[0022] Here, the tray may rotate from a first position that closes the first opening to a second position that opens the first opening and allows coins to fall into the first opening.

[0023] When coins are placed on the tray, the tray is in a first position that closes the first opening. This prevents coins from being directly inserted into the first opening. When the tray rotates from the first position to the second position, the first opening is opened and coins fall from the tray into the first opening. The coin processing device offers high operability for inserting coins.

[0024] The device housing may have a guide wall for guiding the coin into the first opening.

[0025] The guide wall can guide coins falling from the inclined tray to the first opening. Coins can be stably inserted from the tray into the first opening.

[0026] The device housing may support the tray so that the first pin moves between the position of the first axis and the position of the second axis.

[0027] When inserting coins from the tray into the second opening, the operator moves the tray. In a coin processing device having multiple openings, including the first and second openings, the operator is prevented from mistakenly inserting coins into the wrong opening. The coin processing device offers high operability in terms of coin insertion.

[0028] The tray may slide at least horizontally.

[0029] The operator can select the coin slot by sliding the tray, thus preventing accidental insertion into the wrong slot. If the sliding direction is horizontal, the operator can easily slide the tray without spilling the coins.

[0030] The tray may be configured such that, with the first pin engaged with the device housing at the position of the second axis, the first end is lifted, causing coins to fall from the second end into the second opening.

[0031] The operator can lift the first end of the tray, causing the numerous coins placed on the tray to sequentially drop from the second end of the tray into the second opening. This makes it easy for the operator to insert coins into the second opening. In addition, whether inserting coins into the first or second opening, the operator lifts the first end of the tray. Since the operation of inserting coins from the tray into the first or second opening is the same, operator errors are suppressed.

[0032] When the first pin is positioned on the second axis, a portion of the tray may protrude outward from the side of the device housing.

[0033] If the tray is designed so that a portion of it protrudes outward from the side of the device housing when the tray is moved, the device housing itself can be made smaller.

[0034] The device housing may have a guide groove that engages with the first pin, and the guide groove extends from the position of the first axis to the position of the second axis.

[0035] With the first pin engaged in the guide groove, the tray can move smoothly relative to the device housing.

[0036] The device housing may have a locking mechanism that engages with the first pin at the position of the first axis.

[0037] The locking mechanism engages with the first pin, restraining the tray from moving. Furthermore, the locking mechanism engages with the first pin, allowing the device housing to hold the tray in place and prevent it from detaching. The tray may be rotatable at the position of the first axis while the locking mechanism is engaged with the first pin. Since the tray does not move during rotation, the operator can reliably insert coins from the tray into the first opening.

[0038] The locking mechanism may be switched between a state engaged with the first pin and a state in which the engagement with the first pin is released.

[0039] If the locking mechanism releases the engagement with the first pin, the tray can move. Also, the tray in which the first pin has moved to the position of the second axis can rotate at that position.

[0040] The locking mechanism may release the engagement with the first pin when an error of the device is cleared or coins on the tray are removed.

[0041] When an error of the device is cleared or coins on the tray are removed, the coins placed on the tray are sent to the discharge port through the second opening. By the locking mechanism releasing the engagement with the first pin, the operator can insert coins from the tray into the second opening.

[0042] The coin processing device may further include a display unit that guides an operation procedure to the operator when releasing the engagement with the first pin.

[0043] When releasing the engagement with the first pin, it is a case of performing an exceptional operation including clearing an error as described above. If the operation procedure is guided to the operator through the display unit, incorrect operations by the operator can be suppressed.

[0044] The coin processing device may further include a controller that outputs a command signal to the locking mechanism, and the locking mechanism may switch from a state engaged with the first pin to a state in which the engagement is released upon receiving a release command from the controller.

[0045] When the engagement of the locking mechanism is released by manual operation of the operator, it may happen that the operator accidentally releases the engagement with the first pin. If the locking mechanism is controlled by the controller, incorrect operations by the operator can be suppressed.

[0046] The tray has a first pin rotatably engaged with the device housing at the position of the first axis and a second pin rotatably engaged with the device housing at the position of the second axis. When the first end of the tray is lifted with the first pin engaged with the device housing, coins are dropped from the second end of the tray, which is opposite to the first end, into the first opening. When the second end of the tray is lifted with the second pin engaged with the device housing, coins may be dropped from the first end into the second opening.

[0047] By lifting the first end of the tray, the operator can sequentially drop a large number of coins placed on the tray from the second end of the tray into the first opening. It is easy for the operator to insert coins into the first opening.

[0048] By lifting the second end of the tray, the operator can sequentially drop a large number of coins placed on the tray from the first end of the tray into the second opening. It is easy for the operator to insert coins into the second opening.

[0049] Also, since the positions for lifting the tray are opposite, the operator can clearly distinguish between the case of dropping coins from the tray into the first opening and the case of dropping coins from the tray into the second opening. The coin handling device can suppress misoperations such as accidentally dropping coins into the first opening or accidentally dropping coins into the second opening.

[0050] The device housing has a first locking mechanism engaged with the first pin and a second locking mechanism engaged with the second pin. When dropping coins into the first opening, the first locking mechanism engages with the first pin and the second locking mechanism releases the engagement of the second pin. When dropping coins into the second opening, the first locking mechanism releases the engagement of the first pin and the second locking mechanism engages with the second pin.

[0051] The tray can rotate at the position of the first axis when the first locking mechanism engages with the first pin and the second locking mechanism disengages from the second pin. Furthermore, the device housing can hold the tray in place so that it does not detach from the device housing when the first locking mechanism engages with the first pin.

[0052] The tray can rotate at the position of the second axis when the second locking mechanism engages with the second pin and the first locking mechanism disengages from the first pin. Furthermore, the engagement of the second locking mechanism with the second pin allows the device housing to hold the tray in place so that it does not detach from the device housing.

[0053] The first locking mechanism may switch from a state where it is engaged with the first pin to a state where it is disengaged upon receiving a disengagement command from the controller, and the second locking mechanism may switch from a state where it is engaged with the second pin to a state where it is disengaged upon receiving a disengagement command from the controller.

[0054] The state of the first and second locking mechanisms switches according to the controller's command, preventing the tray from rotating in the wrong direction. This suppresses erroneous operation of the coin processing device.

[0055] The aforementioned coin processing device offers improved operability in terms of inserting or removing coins.

[0057] The following describes an embodiment of a coin processing device with reference to the drawings. The coin processing device described here is illustrative.

[0058] (Overall structure of the coin processing device) Figure 1 shows the external appearance of the coin processing device 1. Figure 2 shows the internal structure of the coin processing device 1. Figure 3 is a block diagram of the coin processing device 1. The coin processing device 1 performs at least the coin deposit process. The coin deposit process is the process in which the coin processing device 1 counts the coins and then stores the coins inside the coin processing device 1.

[0059] The coin processing device 1 has a deposit section 11. The deposit section 11 accepts coins. The deposit section 11 has a first opening 31. The first opening 31 is formed in the housing 10 of the coin processing device 1, as shown in Figure 4. The deposit section 11 can feed coins into the device through the first opening 31. Details of the structure of the deposit section 11 will be described later.

[0060] The coin processing device 1 has a transport unit 12. The transport unit 12 transports coins. The transport unit 12 has a rotating disk 121. The transport unit 12 also has a transport path 122. Coins that have passed through the first opening 31 are sent to the rotating disk 121. The rotating disk 121 sends the coins one by one to the transport path 122. The transport unit 12 transports the coins one by one along the transport path 122. Alternatively, a supply disk for supplying coins may be provided adjacent to the rotating disk 121, and the supply disk may grip the coins on the rotating disk 121 one by one and send them to the transport path 122.

[0061] The coin processing device 1 has an identification unit 13. The identification unit 13 is located in the middle of the transport path 122. The identification unit 13 includes sensors such as a magnetic sensor and an optical sensor such as an image sensor, and identifies coins. The identification unit 13 identifies at least the denomination and authenticity of the coins and counts the coins.

[0062] The transport unit 12 has a plurality of sorting units 123. In the illustrated example, the transport unit 12 has 11 sorting units 123. The sorting units 123 are arranged along the transport path 122 downstream of the identification unit 13. As shown by the dashed arrows in Figure 2, the sorting units 123 are connected via chutes to the return unit 14, the first storage unit 15, the second storage unit 16, or the third storage unit 114, which will be described later. The sorting units 123 send the coins being transported by the transport path 122 to the return unit 14, the first storage unit 15, the second storage unit 16, or the third storage unit 114 according to the identification result. The third storage unit 114 is a storage unit for counterfeit coins or coins suspected of being counterfeit. Note that the correspondence between the sorting units 123 and each transport destination is just an example and is not limited thereto.

[0063] The coin processing device 1 has a return unit 14. Coins that cannot be accepted by the coin processing device 1 are returned to the operator of the coin processing device 1 through the return unit 14.

[0064] The coin processing device 1 has a first storage section 15. The first storage section 15 stores coins. In the example in Figure 2, the first storage section 15 includes eight storage areas 151 to 158. Each of the storage areas 151 to 158 is connected to a different sorting section 123. The eight storage areas 151 to 158 store coins, for example, by denomination.

[0065] The coin processing device 1 has a second storage section 16. The second storage section 16 stores coins. The second storage section 16 is connected to a sorting section 123 that is different from the storage areas 151 to 158 of the first storage section 15.

[0066] As shown in Figure 3, the coin processing device 1 has a reader 18. The reader 18 reads the information of the operator who operates the coin deposit device 5. As will be described later, when an error clearing operation is performed on the coin processing device 1, an authorized person operates the coin processing device 1. The reader 18 is used to authenticate the operator who performs the error clearing operation.

[0067] The coin processing device 1 has a touch panel 19. The touch panel 19 is an operating unit that receives input from the operator. The touch panel 19 also serves as a display unit.

[0068] The coin processing device 1 has a storage unit 110. The storage unit 110 stores various information. For example, the storage unit 110 stores the amount of coins stored in the first storage unit 15 and the amount of coins stored in the second storage unit 16. The amount includes at least the denomination and number of coins. The amount may also include the total value of the coins. The storage unit 110 is, for example, a memory.

[0069] The coin processing device 1 has a communication unit 111. The communication unit 111 performs communication between devices.

[0070] The coin processing device 1 has a controller 112. The controller 112 realizes the processing that the coin processing device 1 performs by controlling each part. The controller 112 may be implemented in one or more electrical circuits or processing circuits, including one or more general-purpose processors, application processors, integrated circuits, ASICs (Application Specific Integrated Circuits), CPUs (Central Processing Units), conventional circuits, and / or combinations thereof, which are programmed to perform each processing.

[0071] The locking mechanism 113 of the coin processing device 1 will be described later.

[0072] (Structure of the deposit section) The deposit section 11 of the coin processing device 1 has a structure that allows a large amount of coins to be efficiently inserted into the device. Figure 4 is an enlarged view of the deposit section 11. The deposit section 11 is equipped with a tray 2. As shown in Figure 1 or Figure 4, the tray 2 is mounted on a mounting section 3 of the housing 10. The mounting section 3 is located at the front of the upper surface of the housing 10.

[0073] In the following explanation, the front-to-back, left-to-right, and up-to-down directions are defined as follows: The front of the coin processing device 1 is the side where the deposit section 11 or return section 14 is located, which corresponds to the front left side of the paper in the left diagram of Figure 1 and the front right side of the paper in the right diagram of Figure 1. The rear of the coin processing device 1 is the side opposite to the side where the deposit section 11 or return section 14 is located, which corresponds to the back right side of the paper in the left diagram of Figure 1 and the back left side of the paper in the right diagram of Figure 1.

[0074] The left-right direction is perpendicular to the front-back direction. When the operator is standing in front of the coin processing device 1, facing the device, the left side of the operator is called the left of the coin processing device 1, and the right side of the operator is called the right of the coin processing device 1. The up-down direction is perpendicular to both the front-back and left-right directions.

[0075] As shown in the lower diagram of Figure 4, the mounting portion 3 opens onto the upper surface of the housing 10 and is recessed downward from the upper surface of the housing 10. The mounting portion 3 extends horizontally from the left end to the right end of the housing 10.

[0076] The mounting section 3 has a first opening 31. As will be described later, coins are inserted into the first opening 31 from the tray 2. The first opening 31 sends the inserted coins into the device. As mentioned above, the first opening 31 is connected to the rotating disk 121 of the transport section 12. The coins inserted into the first opening 31 enter the rotating disk 121 (see also Figure 2).

[0077] The first opening 31 faces upward at the bottom of the mounting portion 3 (see also Figure 6). The first opening 31 is located on the right side of the mounting portion 3.

[0078] The mounting section 3 has a guide wall 30. As shown in the right diagram of Figure 1 or in Figure 6, the guide wall 30 extends diagonally upward from the edge of the first opening 31. The guide wall 30 guides coins from the tray 2 to the first opening 31, as will be described later.

[0079] The mounting section 3 has a second opening 32. As will be described later, coins are inserted into the second opening 32 from the tray 2. The second opening 32 faces upward at the bottom of the mounting section 3 (see also Figure 6). The second opening 32 is located on the left side of the mounting section 3. The first opening 31 and the second opening 32 are separated horizontally.

[0080] The second opening 32 is connected to the discharge port 101. The discharge port 101 opens on the left side of the housing 10, as shown in the right-hand diagram of Figure 1. As shown in Figure 6, a chute 102 extending diagonally downward connects the second opening 32 and the discharge port 101. Coins inserted into the second opening 32 are discharged from the discharge port 101 through the chute 102. If a box or bag (e.g., a pouch) for receiving coins is attached to the discharge port 101, the coins inserted into the second opening 32 will be contained in the box or bag.

[0081] Tray 2 is mounted on the mounting section 3 of the housing 10. Tray 2 is mounted on the mounting section 3 from above. Once mounted on the mounting section 3, tray 2 is exposed upwards to the outside of the housing 10.

[0082] Coins are placed on tray 2. The operator places the coins to be inserted into the coin processing device 1 onto tray 2. Tray 2 has an elongated shape, with its length in the left-to-right direction being longer than its length in the front-to-back direction. Tray 2 can hold more coins than the number of coins that can pass through the first opening 31 simultaneously.

[0083] Figure 5 shows tray 2. Tray 2 has a placement surface 21. Coins are placed on the placement surface 21. The placement surface 21 is inclined diagonally downward from the first end, i.e., the left end, to the second end, i.e., the right end. Coins placed on the placement surface 21 tend to move from the first end to the second end due to the inclination of the placement surface 21.

[0084] The mounting surface 21 is surrounded by three side walls 22. There is no side wall at the second end of the tray 2. When inserting coins from the tray 2 into the first opening 31 or the second opening 32, the coins fall from the second end of the tray 2 and enter the first opening 31 or the second opening 32.

[0085] The tray 2 has an overall shape that is open upwards. The operator can place coins on the placement surface 21 from above the tray 2. The operator can place more coins on the tray 2 at once than the number of coins that can pass through the first opening 31 or the second opening 32 simultaneously.

[0086] The tray 2 has a handle 24. The handle is integrally formed with the side wall 22 at the first end. As will be described later, the operator can tilt the tray 2 by holding the handle 24 and lifting the first end of the tray 2.

[0087] The mounting surface 21 has a plurality of through holes 23. The plurality of through holes 23 are formed at the second end of the tray 2. The plurality of through holes 23 are spaced apart from each other. The through holes 23 penetrate the mounting surface 21 in the thickness direction. The through holes 23 have the function of removing foreign matter. When a large number of coins are placed on the mounting surface 21, the foreign matter falls off the mounting surface 21 through the through holes 23. The through holes 23 are smaller in size than the coins. As hypothetically shown in Figure 5, a catcher 25 is detachably attached to the tray 2. The catcher 25 is attached to the lower surface at the second end of the tray 2. The catcher 25 catches the foreign matter that falls through the through holes 23. This prevents foreign matter from being introduced into the first opening 31.

[0088] The tray 2 has pins 26, 26. The pins 26, 26 are located near the second end of the tray 2. The pins 26 protrude forward and backward from the side of the side wall 22, respectively. The pins 26, 26 may also be formed by a shaft 260 that penetrates the front side wall 22 and the rear side wall 22. The shaft 260 can achieve the high rigidity required of the pins 26, 26.

[0089] As shown in Figure 6, the pin 26 engages with the guide groove 33 of the mounting portion 3. The guide groove 33 is provided on the rear side surface 34 and the front side surface 34 (see Figure 4) of the recessed mounting portion 3. The guide groove 33 extends in the left-right direction. More specifically, the right end of the guide groove 33 is located near the first opening 31. The left end of the guide groove 33 is located near the second opening 32.

[0090] The guide groove 33 includes a first horizontal section 331 extending horizontally from the right end to the left, a second horizontal section 332 extending horizontally from the left end to the right, and an inclined section 333 that is angled between the first horizontal section 331 and the second horizontal section 332. The second horizontal section 332 is located above the first horizontal section 331.

[0091] The pin 26 can move left and right along the guide groove 33 between its right and left ends. As shown by the dashed line in the upper part of Figure 6, when the tray 2 is in a horizontal position with the pin 26 positioned at the right end of the guide groove 33, the tray 2 closes the first opening 31 and the second opening 32. The tray 2 is also capable of accepting coins in the mounting section 3, as shown in the upper part of Figure 4.

[0092] The operator can hold the handle 24 of the tray 2 and slide the tray 2 to the left while keeping it in a substantially horizontal position until the pin 26 is positioned at the left end of the guide groove 33 (see the dashed arrow in the lower diagram of Figure 6). Even if there are coins on the tray 2, the operator can move the tray 2 without dropping the coins.

[0093] The mounting portion 3 has a notch 35 at its left end. As shown in the right diagram of Figure 1, the notch 35 is formed on the left side surface of the housing 10 as a recess extending downward from the upper end. A portion of the tray 2 can move out of the mounting portion 3 through the notch 35. As shown by the dashed line in the lower diagram of Figure 4 or the lower diagram of Figure 6, when the pin 26 is positioned at the left end of the guide groove 33, a portion of the tray 2 protrudes outward from the left side surface of the housing 10. The tray 2 can maintain a horizontal position even when the pin 26 is positioned at the left end of the guide groove 33.

[0094] Here, the height HR at the second end of tray 2 is different from the height HL at the first end. The height HR at the second end is higher than the height HL at the first end. Also, the height position of the second opening 32 is set higher than the height position of the first opening 31 (see the dotted line in the lower part of Figure 6). As shown by the dashed line in the upper part of Figure 6, tray 2, which has a height difference between the left and right sides, closes both the first opening 31 and the second opening 32. When tray 2 moves horizontally along the guide groove 33, the second end of tray 2 may interfere with the edge of the second opening 32.

[0095] In contrast, the guide groove 33 has a second horizontal section 332 positioned above the first horizontal section 331. When the pin 26 engages with the second horizontal section 332, the tray 2 is displaced upward, thus avoiding interference between the second end of the tray 2 and the edge of the second opening 32.

[0096] The mounting section 3 has a locking mechanism 113. The locking mechanism 113 switches between locking and unlocking the tray 2. The tray 2 switches between a state in which it is restrained by the locking mechanism 113 to prevent horizontal movement and a state in which horizontal movement is permitted.

[0097] As shown in Figure 6, the locking mechanism 113 has a locking lever 40. The locking lever 40 is located adjacent to the rear side surface 34 of the recessed mounting portion 3 in the upper surface of the housing 10, near the right end of the guide groove 33. The locking lever 40 is also located adjacent to the front side surface 34 of the mounting portion 3, near the right end of the guide groove 33.

[0098] The lock lever 40 has a hook at its tip. The base end of the lock lever 40 is pivotally supported by the housing 10. The lock lever 40 rotates between a state in which it is engaged with the pin 26 of the tray 2 (see enlarged view 601 in Figure 6) and a state in which it is not engaged with the pin 26 of the tray 2 (see enlarged view 602 in Figure 6).

[0099] The locking mechanism 113 includes, for example, a solenoid actuator. The solenoid actuator rotates the locking lever 40. The locking mechanism 113 receives a control signal from the controller 112 and switches between locking and unlocking the tray 2.

[0100] As mentioned above, when the locking mechanism 113 is engaged with the pin 26 of the tray 2, the tray 2 cannot move horizontally with the pin 26 positioned at the right end of the guide groove 33. On the other hand, as shown in the upper diagram of Figure 6, the tray 2 can rotate clockwise from a horizontal position around the pin 26. Note that the clockwise direction is the direction when standing in front of the coin processing device 1 and looking at the coin processing device 1.

[0101] When the operator lifts the handle 24 at the first end of the tray 2, the tray 2 tilts around a horizontal first axis Ax1, which corresponds to the position of the right end of the guide groove 33. When the tray 2 is in the tilted position, the first opening 31 opens and the second end of the tray 2 faces the first opening 31. Coins placed on the mounting surface 21 fall from the second end of the tray 2 and are inserted into the first opening 31 (see the white arrow in the upper diagram of Figure 6). The guide wall 30 guides the coins that have fallen from the tray 2 to the first opening 31. At this time, because the locking mechanism 113 is engaged with the pin, the second end of the tray 2 remains above the first opening 31. Also, the tray 2 does not detach from the housing 10.

[0102] Once the coin insertion is complete, the operator lowers the first end of the tray 2, which was being held up, changing the tray 2 from an inclined position to a horizontal position. The tray 2 then closes the first opening 31 and the second opening 32. The operator can then place coins on the tray 2 again.

[0103] When the locking mechanism 113 is released, the operator can slide the tray 2 to the left by holding the handle 24 at the first end of the tray 2. The tray 2 can move until the pin 26 of the tray 2 reaches the left end of the guide groove 33. When the pin 26 of the tray 2 reaches the second end of the guide groove 33, the second opening 32 opens, as shown by the dashed line in the lower diagram of Figure 6. The first opening 31 also opens. The second end of the tray 2 is located above the second opening 32.

[0104] With the pin 26 positioned at the left end of the guide groove 33, the tray 2 can rotate clockwise from a horizontal position around the pin 26, as shown in the lower diagram of Figure 6.

[0105] The operator lifts the handle 24 at the first end of the tray 2, causing the tray 2 to tilt around the second axis Ax2, which corresponds to the position of the left end of the guide groove 33. The second axis Ax2 is parallel to the first axis Ax1. When the tray 2 tilts, the second end of the tray 2 faces the second opening 32. Coins placed on the mounting surface 21 fall from the second end of the tray 2 and are inserted into the second opening 32 (see the white arrow in the lower diagram of Figure 6). At this time, the tray 2 does not come off the housing 10 because the two front and rear pins 26 of the tray 2 are engaged with the guide groove 33.

[0106] Once the coin insertion is complete, the operator lowers the first end of the tray 2, which was being held up, changing the tray 2 from an inclined position to a horizontal position. The operator then slides the tray 2 to the right by holding the handle 24 at the first end of the tray 2. The tray 2 can move until the pin 26 of the tray 2 reaches the right end of the guide groove 33. When the pin 26 of the tray 2 reaches the right end of the guide groove 33, the tray 2 becomes horizontal and closes the first opening 31 and the second opening 32. The locking mechanism 113 can engage with the pin 26.

[0107] (Procedure for inserting coins into the coin processing device) Next, the procedure for inserting coins into the coin processing device 1 will be explained with reference to Figure 7. Figure 7 is a transition diagram showing the operation of inserting coins from tray 2 into the first opening 31 and the operation of inserting coins from tray 2 into the second opening 32.

[0108] Step P71 in Figure 7 shows the standby state of the coin processing device 1. The tray 2 has a pin 26 positioned at the right end of the guide groove 33, and the locking mechanism 113 engages with the pin 26. The tray 2 cannot be removed from the housing 10.

[0109] Tray 2 is in a horizontal position. Tray 2 closes the first opening 31 and the second opening 32. Because the first opening 31 and the second opening 32 are closed, it is possible to prevent the operator from inadvertently inserting coins or foreign objects into the first opening 31.

[0110] The operator places coins on tray 2. Because tray 2 is widely open upwards, the operator can place a large number of coins on it at once. Also, because tray 2 is in a horizontal position, it can stably hold a large number of coins. Furthermore, because the placement surface 21 is inclined, coins tend to move towards the second end of tray 2.

[0111] Step P72 in Figure 7 shows the state in which a coin is inserted into the first opening 31. The pin 26 is located at the right end of the guide groove 33, and the locking mechanism 113 engages with the pin 26.

[0112] Since tray 2 is not constrained in the rotational direction, the operator can hold the handle 24 of tray 2 and lift the first end of tray 2. Tray 2 rotates around the first axis Ax1 and tilts so that the second end of tray 2 is facing downwards. Coins placed on tray 2 fall from the second end of tray 2 and are inserted into the first opening 31. As described above, the guide wall 30 guides the coins into the first opening 31. The operator can insert coins from tray 2 into the first opening 31 smoothly and without spilling.

[0113] If an error occurs, such as a coin jam, while inserting coins into the first opening 31, the operation of the coin processing device 1 will stop. In order to clear the error, the first opening 31 may be opened wider. Coins that are on tray 2 must be removed from tray 2.

[0114] Furthermore, not only when an error occurs, but also, for example, if the wrong coin is placed on tray 2, the operator will want to remove the coin from tray 2.

[0115] The coin processing device 1 can quickly remove coins from tray 2. Specifically, the operator inserts the coins from tray 2 into the second opening 32.

[0116] The operator first releases the lock mechanism 113 by operating the touch panel 19 of the coin processing device 1. Error release operations are performed by authorized operators. The operator performing the error release operation is authenticated using the reader 18. Authorized operators release the lock mechanism 113 by operating the touch panel 19.

[0117] If an operator wants to remove the coins from tray 2 rather than clear an error, they can operate the touch panel 19 to, for example, cancel the deposit process in the coin processing device 1.

[0118] Upon receiving input from the operator, the controller 112 causes the locking mechanism 113 to release the lock. Once the locking mechanism 113 releases the engagement of the pin 26, the operator can move the tray 2 horizontally.

[0119] When the locking mechanism 113 is released, the touch panel 19 of the coin processing device 1 may guide the operator through the operating procedure. Following the operating procedure displayed on the touch panel 19, the operator can hold the handle 24 of the tray 2 and slide the tray 2 to the left while keeping it in a horizontal position (see step P73 in Figure 7). The guidance of the operating procedure is expected to enable the operator to move the tray 2 without dropping any coins. The tray 2 is moved until the pin 26 is positioned at the left end of the guide groove 33, that is, until the tray 2, which is being moved to the left by the operator, can no longer be moved to the left. The guidance of the operating procedure is expected to enable the operator to move the tray 2 to the correct position.

[0120] Step P74 in Figure 7 shows the state in which coins are inserted into the second opening 32. With the pin 26 positioned at the left end of the guide groove 33, the operator holds the handle 24 of the tray 2 and lifts the first end of the tray 2. Even with the pin 26 positioned at the left end of the guide groove 33, the tray 2 is not constrained in the rotational direction. The tray 2 rotates around the second axis Ax2 and tilts so that the second end of the tray 2 is facing downwards. The coins placed on the tray 2 fall from the second end of the tray 2 and are inserted into the second opening 32. The coins inserted into the second opening 32 are discharged through the discharge port 101 to the left side of the housing 10. The operator may attach a box or bag to the discharge port 101 to receive the coins if necessary. The coins discharged from the discharge port 101 are placed in the box or bag.

[0121] As described above, the housing 10 of the coin processing device 1 has a first opening 31. The housing 10 rotatably supports the tray 2 at the position of the first axis Ax1. When the operator tilts the tray 2, coins fall from the tray 2 into the first opening 31. The operator can use the tray 2 to directly insert a large number of coins from the tray 2 into the first opening 31. The coin processing device 1 offers high operability in terms of coin insertion.

[0122] The housing 10 also has a second opening 32. The housing 10 rotatably supports the tray 2 at the position of the second axis Ax2. When the operator tilts the tray 2, coins fall from the tray 2 into the second opening 32. The operator can directly insert a large number of coins from the tray 2 into the second opening 32. The operator can send coins from the tray 2 through the second opening 32 to the discharge port 101. The coin processing device 1 also offers high operability in removing coins from the tray 2.

[0123] The positions of the first axis Ax1 and the second axis Ax2 are different, and the first opening 31 and the second opening 32 are separated horizontally. The operator can select the opening 31 or 32 into which to insert coins by sliding the tray 2. The operator can clearly distinguish between inserting coins from the tray 2 into the first opening 31 and inserting coins from the tray 2 into the second opening 32. The coin processing device 1 can prevent errors such as accidentally dropping coins into the first opening 31 or the second opening 32.

[0124] Furthermore, whether dropping coins from tray 2 into the first opening 31 or into the second opening 32, the operator lifts the first end of tray 2. Since the operation is the same, operator errors are suppressed.

[0125] When tray 2 is moved to the left, a portion of tray 2 protrudes outward from the left side of the housing 10. This structure has the advantage of allowing the housing 10 of the coin processing device 1 to be made smaller.

[0126] Tray 2 cannot be removed from the housing 10. When an unspecified number of customers operate the coin processing device 1, if tray 2 detaches from the coin processing device 1, there is a risk of losing tray 2. A structure that prevents tray 2 from detaching from the housing 10 can prevent the loss of tray 2. However, the structure that prevents tray 2 from being removed from the housing 10 is not an essential structure in the technology disclosed herein.

[0127] The housing 10 has a locking mechanism 113. The locking mechanism 113 restrains the horizontal movement of the tray 2 during normal use of the coin processing device 1. This prevents the operator from accidentally moving the tray 2. Also, when coins are inserted into the first opening 31 by tilting the tray 2, the tray 2 does not move horizontally. The operator can stably insert coins into the first opening 31 using the tray 2.

[0128] Furthermore, the locking mechanism 113 is not released by manual operation by the operator. The release of the locking mechanism 113 is controlled by the controller 112 through operation of the touch panel 19. This prevents the operator from accidentally releasing the engagement of the pin 26.

[0129] (Modified Version) Figure 8 shows a modified version of the coin processing device 1. The tray 20 of the coin processing device 1 has a first pin 261 and a second pin 262.

[0130] The first pin 261 corresponds to pin 26 of the tray 2. The first pin 261 is located near the second end of the tray 20. When the tray 20 mounted on the mounting section 3 is in a horizontal position, the first pin 261 is located at the position of the first axis Ax1.

[0131] The second pin 262 is located at the first end of the tray 20. When the tray 20 mounted on the mounting section 3 is in a horizontal position, the second pin 262 is located at the position of the second axis Ax2.

[0132] The first pin 261 and the second pin 262 protrude from the front and rear sides of the tray 20, respectively.

[0133] The tray 20 is mounted on the mounting section 3. The tray 20 can be changed from a horizontal position to an inclined position. More specifically, as shown in the upper diagram of Figure 8, the tray 20 can rotate around the first pin 261 in a direction that lifts the first end of the tray 20. The tray 20 can also rotate around the second pin 262 in a direction that lifts the second end of the tray 20, as shown in the lower diagram of Figure 7.

[0134] The mounting portion 3 has a first locking mechanism and a second locking mechanism. The first locking mechanism has a first locking lever 41. The first locking lever 41 is located near the first pin 261 and switches between a state in which it is engaged with the first pin 261 and a state in which it is not engaged with the first pin 261.

[0135] The second locking mechanism has a second locking lever 42. The second locking lever 42 is located near the second pin 262 and switches between a state in which it is engaged with the second pin 262 and a state in which it is not engaged with the second pin 262.

[0136] The first locking mechanism has an actuator, such as a solenoid actuator, that moves the first locking lever 41. The controller 112 outputs a control signal to the first locking mechanism.

[0137] The second locking mechanism has an actuator, such as a solenoid actuator, that moves the second locking lever 42. The controller 112 outputs a control signal to the second locking mechanism.

[0138] When the operator inserts coins placed on the tray 20 into the first opening 31, the first lock lever 41 engages with the first pin 261, as shown in the enlarged view 801 of the upper part of Figure 8. The second lock lever 42 disengages the second pin 262, as shown in the enlarged view 802. When the operator lifts the first end of the tray 20, the tray 20 rotates and tilts around the first pin 261, i.e., the first axis Ax1. Coins fall from the second end of the tray 20 and are inserted into the first opening 31 (see the white arrow in the upper part of Figure 8).

[0139] When inserting coins placed on tray 20 into the second opening 32, the first lock lever 41 disengages the first pin 261, as shown in the enlarged view 803 in the lower part of Figure 8. The second lock lever 42 engages with the second pin 262, as shown in the enlarged view 804. When the operator lifts the second end of tray 20, tray 20 rotates and tilts around the second pin 262, i.e., the second axis Ax2. Coins fall from the first end of tray 20 and are inserted into the second opening 32 (see the white arrow in the lower part of Figure 8).

[0140] Since the direction in which the tray 20 is tilted differs depending on whether a coin is inserted into the first opening 31 or the second opening 32, operator error is suppressed.

[0141] Furthermore, since the states of the first locking mechanism and the second locking mechanism are switched according to the command from the controller 112, the tray 20 cannot be rotated in the wrong direction. This is also advantageous in suppressing erroneous operation of the coin processing device.

[0142] Furthermore, since the tray 20 does not protrude outside the housing 10, it is not necessary to secure space for the tray 20 to protrude when installing the coin processing device 1. The coin processing device 1 can be installed with its left side in contact with a wall.

[0143] Figure 9 schematically shows a modified example of the tray structure. The modified tray 5 has a first tray 51 and a second tray 52. ​​The first tray 51 and the second tray 52 are arranged side by side in the left-right direction and are connected to each other. As shown in Figure 10 or Figure 11, the first tray 51 and the second tray 52 can rotate relative to each other around an axis extending in the front-rear direction at the connection point.

[0144] The end of the second tray 52 can also rotate around an axis extending in the front-rear direction relative to the housing 10 of the coin processing device. The pivot shaft 521 of the second tray 52 engages with a groove 53 formed in the housing 10. The pivot shaft 521 can be displaced vertically along the groove 53.

[0145] Figure 9 shows the standby state of the tray 5. In the standby state with the tray 5 mounted on the mounting section 3 of the housing 10, the mounting surface 50 of the tray 5 is inclined diagonally downward from the right end to the left end. The direction of inclination of the mounting surface 50 is downward as it moves away from the opening 55 of the coin processing device (see Figure 10), and coins placed on the mounting surface 50 tend to move away from the opening 55 due to the inclination of the mounting surface 50. The opening 55 is an opening that connects to the rotating disc 121 of the transport section of the coin processing device.

[0146] The standby state of tray 5 is detected by sensor 57. Sensor 57 may be, for example, a limit switch. When tray 5 is mounted on mounting section 3, sensor 57 outputs an ON signal to controller 112.

[0147] The opening 55 is located above the mounting surface 50 of the tray 5 in the standby state, and the housing 10 has a step 103 between the opening 55 and the mounting surface 50.

[0148] The opening 55 is opened and closed by a shutter 56. Figure 9 shows the shutter 56 in the closed position of the opening 55. As shown in Figure 10, the shutter 56 opens the opening 55 by moving away from the tray 5. The controller 112 controls the opening and closing of the shutter 56.

[0149] Figure 10 shows the coin insertion procedure. As shown in step P101, coins are placed on tray 5. Before coin insertion from tray 5 begins, controller 112 opens shutter 56.

[0150] In step P102, the operator lifts the left end of the tray 5 on which the coins are placed on the mounting surface 50 upward (see solid arrow). The first tray 51 moves upward while rotating relative to the second tray 52, and as the first tray 51 moves upward, the pivot shaft 521 moves upward within the groove 53, causing the second tray 52 to move upward as well. As the second tray 52 moves upward, it approaches the opening 55. The gap between the lower end of the shutter 56 and the second tray 52 narrows.

[0151] In step P103, when the operator lifts the left end of tray 5 further upward, the inclination of the mounting surface 50 of tray 5 increases, causing the coins placed on the mounting surface 50 to slide down towards the opening 55. As the second tray 52 moves upward, the gap between the lower end of the shutter 56 and the second tray 52 narrows, allowing the coins to pass through the opening 55 smoothly, while preventing large foreign objects from passing through the opening 55.

[0152] Figure 11 shows the procedure for resolving a blockage in the opening 55 during coin insertion. In step P104, the operator lowers the left end of the tray 5. As the first tray 51 and the second tray 52 move downward, the gap between the lower end of the shutter 56 and the second tray 52 widens. This resolves the blockage in the opening 55.

[0153] In step P105, when the tray 5 is mounted on the mounting section 3, the mounting surface 50 tilts downward to the left. Due to the tilt of the mounting surface 50, coins placed on the mounting surface 50 slide away from the opening 55 (see solid arrow). This prevents coins from remaining in the opening 55.

[0154] In step P106, if the sensor 57 detects that the tray 5 is in standby mode, the controller 112 closes the shutter 56. Since there are no coins remaining in the opening 55, the shutter 56 can close the opening 55 without jamming.

[0155] Furthermore, tray 5 may have a link for linking the movement of the first tray 51 and the second tray 52 shown in Figure 10 or Figure 11. An actuator may also be connected to the link, and the actuator moving the link may realize the coordinated movement of the first tray 51 and the second tray 52 shown in Figure 10 or Figure 11.

[0156] Figure 12 shows a modified example of the shutter 56. In this modified example, the blockage of the opening 55 that occurs during coin insertion can be resolved.

[0157] A pusher 58 is positioned in the first opening 31. The pusher 58 is located below the opening 55. The pusher 58 can move from bottom to top across the opening 55, as shown by the solid arrow in Figure 12 (see also Figure 13).

[0158] If coins are jammed in the opening 55, the pusher 58 cannot move upward because it interferes with the jammed coins. When the pusher 58 moves upward, the shutter 56 moves upward.

[0159] As shown by the solid line in Figure 13, the shutter 56 is positioned in an intermediate position when a coin is inserted, so that the shutter 56 can move upward. The intermediate position is between the fully closed position, where the opening 55 is closed (see the dashed line in Figure 12), and the fully open position, where the shutter 56 is positioned at its highest point due to the structure of the coin processing device (see the solid line in Figure 12).

[0160] By setting a margin that allows the shutter 56 to move, the shutter 56 can move upward when the pusher 58 moves upward (see the dashed line in Figure 13). The pusher 58 pushes the coins jammed in the opening 55, thereby clearing the coin jam.

[0161] Figure 14 is a flowchart relating to the control of the shutter 56 and the pusher 58. First, in step S51 after the start, the controller 112 determines whether the deposit operation has started. The process in Figure 14 repeats step S51 until the deposit operation is started.

[0162] If the determination in step S52 is Yes, the controller 112 positions the shutter 56 in the intermediate position. The operator tilts the tray 5, and coins are inserted into the opening 55.

[0163] In step S53, the controller 112 determines whether a coin jam has occurred in the opening 55. If no jam has occurred, the controller 112 determines in step S57 whether coin insertion is complete. If insertion is not complete, the process in Figure 14 returns to step S53 and continues coin insertion.

[0164] If a blockage occurs in the opening 55, the controller 112 moves the pusher 58 upward in step S54. At this time, in step S55, the controller 112 determines whether the load on the pusher 58 to be moved upward is too great. For example, the controller 112 may determine whether the load is too great based on the sensor value that measures the torque of the actuator that raises and lowers the pusher 58.

[0165] If the load on the pusher 58 is large, the pusher 58 will not move upward, or will hardly move, so in step S56 the controller 112 moves the shutter 56 upward from the intermediate position. The controller 112 then moves the pusher 58 upward in step S54.

[0166] If the load on the pusher 58 is still large in step S55, the shutter 56 moves upward again in step S56. The shutter 56 moves in stages upward from the intermediate position until the pusher 58 can move upward.

[0167] If the load on the pusher 58 is not large in step S55, the process in Figure 14 returns to step S53. The controller 112 determines whether a blockage has occurred in the opening 55.

[0168] As shown in the flow chart in Figure 14, if a blockage occurs in the opening 55, the blockage can be cleared. The operator can continue inserting coins, thus improving the usability of the coin processing device.

[0169] In step S57, once the coin insertion is complete, the process shown in Figure 14 returns to step S51. The coin processing device enters a standby state.
