Description

[Technical Field]

[0001] The present invention relates to a paper handling device and a cash processing device, and is suitable for application to a cash register change system used at checkout counters in retail stores such as supermarkets and convenience stores. [Background technology]

[0002] In recent years, cash register change systems that combine a change machine that processes the deposit and withdrawal of banknotes and coins with a POS (Point Of Sales) register connected to a POS system or the like have become widespread. Among these change machines, paper sheet handling devices that process banknotes include a deposit and withdrawal unit that exchanges banknotes with a cashier, a transport unit that transports banknotes, a discrimination unit that discriminates the denomination and authenticity of inserted banknotes, a banknote storage vault that stores reusable banknotes by denomination, and a reject vault that stores banknotes that should not be reused.

[0003] One such paper handling device has been proposed that uses a sensor to detect foreign objects and controls the movement of the shutter based on the detection results, thereby preventing the shutter from closing while a foreign object is trapped (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2015-5247 Summary of the Invention [Problem to be solved by the invention]

[0005] It is desirable for such a paper handling device to be able to properly detect the presence of a foreign object even when the shutter is tilted due to the foreign object being caught.

[0006] The present invention has been made in consideration of the above points, and aims to propose a paper handling device and a cash processing device that are capable of detecting the entrapment of a foreign object. [Means for solving the problem]

[0007] In order to solve the above problem, the paper sheet handling device of the present invention includes a shutter member that opens and closes an opening, a control unit that opens and closes the opening by moving the shutter member in a first direction, a first light emitting unit that is provided on one side of the shutter member in a second direction that intersects with the first direction and that emits a first light in the other direction in the second direction, a second light emitting unit that is provided on the other side of the shutter member in the second direction and that emits a second light in the one direction in the second direction, and a second light emitting unit that is provided on one side of the shutter member in the second direction and that transmits the first light. The shutter device includes a first light passing section, a second light passing section that is provided on the other side of the shutter member in the second direction and that passes the second light, a first light receiving section that is provided on one side of the shutter member in the second direction and that receives the first light that has passed through the first light passing section, and a second light receiving section that is provided on the other side of the shutter member in the second direction and that receives the second light that has passed through the second light passing section, and the control section determines that the shutter member is in a closed state when it obtains a detection result that the first light receiving section has received the first light and a detection result that the second light receiving section has received the second light.

[0008] Furthermore, the cash processing device of the present invention is a cash processing device having a coin handling device that handles coins and a paper sheet handling device that handles paper sheets, wherein the paper sheet handling device comprises a shutter member that opens and closes an opening, a control unit that opens and closes the opening by moving the shutter member in a first direction, a first light emitting unit that is provided on one side of the shutter member in a second direction intersecting the first direction and that emits a first light in the other side of the second direction, a second light emitting unit that is provided on the other side of the shutter member in the second direction and that emits a second light in the one side of the second direction, and a light emitting unit that is provided on the shutter member in the second direction. a first light passing section provided on one side of the shutter member in the second direction and passing the first light; a second light passing section provided on the other side of the shutter member in the second direction and passing the second light; a first light receiving section provided on one side of the shutter member in the second direction and receiving the first light that has passed through the first light passing section; and a second light receiving section provided on the other side of the shutter member in the second direction and receiving the second light that has passed through the second light passing section, and the control section determines that the shutter member is in a closed state when it obtains a detection result that the first light receiving section has received the first light and a detection result that the second light receiving section has received the second light.

[0009] As a result, in the present invention, when the shutter member is tilted just before closing, either the first light receiving unit or the second light receiving unit, which is located on one side of the shutter member in the second direction or the other side of the shutter member in the second direction, is not receiving light, so it can be recognized that a foreign object is trapped and the shutter member is not properly closed. [Effects of the Invention]

[0010] According to the present invention, when the shutter member is tilted immediately before closing, either the first light receiving unit or the second light receiving unit provided on one side of the shutter member in the second direction or the other side of the shutter member in the second direction does not receive light, so it is possible to recognize that a foreign object has been caught and that the shutter member is not in the closed state properly. Thus, a paper sheet handling device and a cash processing device that can detect the catchment of a foreign object can be realized. [Brief explanation of the drawings]

[0012] Hereinafter, modes for carrying out the invention (hereinafter referred to as embodiments) will be described with reference to the drawings.

[0013] [1. Configuration of cash register change system] As shown externally in Figure 1, cash register change system 1 is composed of an upper POS register 2 and a lower change dispenser 3, which are independent devices. This cash register change system 1 is operated by a cashier at a checkout (a so-called cash register) in a retail store such as a supermarket or convenience store when a customer pays for the items they wish to purchase. In the following explanation, the side facing the cashier and the opposite side are referred to as the front and rear, respectively, and left, right, and top and bottom are further defined from the cashier's perspective.

[0014] The POS register 2 is controlled by a built-in register control unit 5. A barcode reader (not shown) is connected to the POS register 2, which recognizes products by reading barcodes attached to them. The display operation unit 6, which is configured, for example, with a touch panel, displays the recognized product's name, price, etc. on a liquid crystal display. The display operation unit 6 also displays input keys for numbers and other items on part of the display screen. When a location on the touch panel corresponding to an input key is pressed, the display operation unit 6 accepts the input corresponding to the input key and transmits it to the register control unit 5. In response, the register control unit 5 performs various processes, such as increasing or decreasing the product quantity or correcting the price. The POS register 2 also has a built-in receipt processing unit 7. The receipt processing unit 7 prints the recognized product's name, price, etc. on a receipt and discharges it from the receipt discharge port 7A.

[0015] On the other hand, the change machine 3 is broadly composed of a banknote deposit and withdrawal device 11 on the right side, a coin deposit and withdrawal device 12 on the left side, and a display and operation unit 13 on the upper front side.

[0016] The banknote deposit and withdrawal device 11 takes in banknotes deposited by a cashier through the banknote deposit and withdrawal port 14 and stores them in the banknote storage vault 15 (banknote storage vaults 15a, 15b, and 15c) (Figure 2), and also takes out banknotes instructed by the cash register control unit 5 from the banknote storage vault 15 (Figure 2) and dispenses them as change from the banknote deposit and withdrawal port 14.

[0017] A coin depositing / dispensing device 12 serving as a coin handling device has a coin depositing port 16 provided at the top on the front surface, and a rejecting port 17 and a coin dispensing port 18 provided below it. The coin depositing / dispensing device 12 takes in coins inserted into the coin depositing port 16 by a cashier and stores them in an internal storage, and also dispenses coins of a denomination and number according to the amount instructed by the cash register control unit 5 from the coin dispensing port 18 as change.

[0018] The display operation unit 13 is configured by a combination of a predetermined display panel and predetermined operation buttons. The display panel of the display operation unit 13 displays the operating status of the banknote deposit and withdrawal device 11 and the coin deposit and withdrawal device 12, and displays, for example, that there is a shortage of coins for change in the coin deposit and withdrawal device 12, that a predetermined sensor has detected an abnormality, and the location of the abnormality. The operation buttons of the display operation unit 13 are pressed by a cashier or the like to receive instructions regarding, for example, the transport of coins.

[0019] A change control unit 21 is also provided inside the change machine 3. The change control unit 21 is configured around a CPU (Central Processing Unit) not shown, and controls the change machine 3 overall by reading and executing various programs from a memory such as a flash memory, and performs various processes such as deposit transactions and withdrawal transactions.

[0020] [2. Configuration of the banknote deposit and withdrawal device] As shown in Figure 2, the banknote deposit and withdrawal device 11 has multiple parts built into the housing that perform various processes related to banknotes, and the change control unit 21 (Figure 1) has overall control over each part (deposit and withdrawal unit 24, transport unit 26, discrimination unit 28, banknote storage vault 15 (banknote storage vaults 15a, 15b, and 15c), and reject collection vault 30).

[0021] The deposit / withdrawal unit 24 is located at the upper front part inside the banknote deposit / withdrawal device 11. This deposit / withdrawal unit 24 has a banknote storage unit 32 having the banknote deposit / withdrawal port 14 on the front side and storing banknotes, a shutter unit 35 (FIG. 3) consisting of a shutter 34 and the like that opens and closes the banknote deposit / withdrawal port 14, and a sensor (not shown) that detects the presence or absence of banknotes in the banknote storage unit 32, etc.

[0022] When a cashier, who is a user, deposits banknotes through banknote deposit / withdrawal port 14 with shutter 34 in the open state and banknote deposit / withdrawal port 14 open, deposit / withdrawal unit 24 closes shutter 34 to close banknote deposit / withdrawal port 14, takes in the deposited banknotes, separates them one by one, and feeds them to transport unit 26. Meanwhile, with shutter 34 in the closed state, deposit / withdrawal unit 24 stores banknotes to be dispensed to a user in banknote storage unit 32 in a state aligned vertically, and dispenses them as change from banknote deposit / withdrawal port 14 with shutter 34 in the open state.

[0023] Conveyance unit 26 conveys rectangular banknotes in the direction of their short edges along a conveyance path using rollers, belts, etc. A blade is provided at the branching point of conveyance unit 26, and rotates under the control of change control unit 21 to switch the destination of the banknotes.

[0024] The validator 28 is located behind the deposit / withdrawal unit 24. While transporting deposited, dispensed, and collected banknotes inside, the validator 28 uses optical elements, magnetic detection elements, etc. to recognize the denomination, authenticity, fitness (whether damaged), and transport status of the banknotes, and notifies the change control unit 21 of the validation results. In response, the change control unit 21 determines the destination of the banknotes based on the obtained validation results.

[0025] The rejected collection box 30 is provided below the deposit / withdrawal unit 24 within the banknote deposit / withdrawal device 11, and has a banknote storage space therein for accumulating and storing banknotes. The rejected collection box 30 is a removable storage box that can be attached to and detached from the banknote deposit / withdrawal device 11. When the reject collection box 30 receives a banknote that has been determined by the transport unit 26 to be a damaged banknote (so-called undamaged note), a banknote that has been determined to be counterfeit, or a banknote of a denomination that is not recyclable, such as a 5,000 note or a 2,000 note, the rejected collection box 30 stores the banknote. When the reject collection box 30 receives a banknote that has been transported by the transport unit 26 during a collection process for collecting a portion of the proceeds from sales of banknotes stored in the banknote storage box 15, the rejected collection box 30 stores the banknote.

[0026] Behind the rejected bill collection box 30, banknote storage boxes 15a, 15b, and 15c (hereinafter collectively referred to as banknote storage boxes 15) are provided in this order from front to rear. Each banknote storage box 15 (banknote storage boxes 15a, 15b, and 15c) is formed in a rectangular parallelepiped shape and has a stage therein for accumulating banknotes. The banknote storage boxes 15a, 15b, and 15c are configured substantially identically to one another, and each is preset with a denomination of banknotes to be stored. When banknotes determined by the validator 28 and the change controller 21 to be minimally damaged and reusable are transported by the transport unit 26 according to their denominations, the banknote storage box 15 accumulates and stores the banknotes inside. Furthermore, when the banknote storage box 15 receives an instruction to feed banknotes from the change controller 21, it separates the accumulated banknotes one by one, feeds them, and hands them over to the transport unit 26.

[0027] In this configuration, the cash register change system 1 has the change control unit 21 controlling each unit based on the results of bill validation by the validator 28, and performs processes such as depositing, dispensing, and collecting bills.

[0028] [3. Shutter Configuration] As shown in Fig. 3, a shutter decorative plate 36 is provided around the banknote deposit and withdrawal slot 14. The shutter decorative plate 36 is a plate-like member fixed to the housing of the banknote deposit and withdrawal device 11, with the upper side inclined slightly backward relative to the vertical direction as a whole, and is made up of a lower decorative plate 38D, an upper decorative plate 38U, a right decorative plate 38R, and a left decorative plate 38L. The banknote deposit and withdrawal slot 14 is configured in a horizontally elongated rectangular shape when viewed from the front.

[0029] The shutter decorative panel 36 has an upper side that is slightly tilted backward relative to the vertical direction, and the shutter 34 also has an upper side that is slightly tilted backward relative to the vertical direction to match the shutter decorative panel 36, and the shutter moving direction, which is the direction in which the shutter 34 moves, also tilts slightly backward relative to the vertical direction at the upper side, along the direction in which the front surface of the shutter 34 extends.However, for convenience of explanation, in the following, the shutter decorative panel 36, the direction in which the front surface of the shutter 34 extends, and the shutter moving direction will be described as being along the vertical direction.

[0030] The lower decorative plate 38D is disposed below the banknote deposit / withdrawal slot 14 and has an upper end surface 38DS, which is a flat surface facing upward along the left-right direction. The upper decorative plate 38U is disposed above the banknote deposit / withdrawal slot 14 and has a lower end surface 38US, which is a flat surface facing downward along the left-right direction. The right decorative plate 38R is disposed to the right of the banknote deposit / withdrawal slot 14 and has a left end surface 38RS, which is a flat surface facing left along the up-down direction. The left decorative plate 38L is disposed to the left of the banknote deposit / withdrawal slot 14 and has a right end surface 38LS, which is a flat surface facing right along the up-down direction. In this way, the banknote deposit / withdrawal slot 14 is surrounded on all four sides by the upper end surface 38DS, the lower end surface 38US, the left end surface 38RS, and the right end surface 38LS in a front view.

[0031] The shutter 34 extends in the vertical direction in accordance with the inclination of the shutter decorative plate 36. The shutter 34 receives the driving force of a shutter drive motor (not shown) and slides along the rear side of the shutter decorative plate 36 in the shutter movable direction, which is the direction along the vertical direction in accordance with the inclination of the shutter decorative plate 36, thereby opening or closing the banknote deposit / withdrawal slot 14. Specifically, the shutter 34 is movable in an opening direction Do, which is a downward direction in the shutter movable direction, and in a closing direction Dc, which is an upward direction in the shutter movable direction.

[0032] 3, the shutter 34 is positioned at the lowest position, exposing the banknote storage unit 32 to the outside. Fig. 3 also shows the fully open state in which the banknote deposit / withdrawal slot 14 is opened to the widest extent among the open states, and in this fully open state, the upper end of the shutter 34 is positioned at approximately the same vertical position as the upper end surface 38DS of the lower decorative plate 38D.

[0033] 5, the shutter 34 is in the uppermost position, blocking the banknote housing unit 32 from the outside. In the closed state, the upper end of the shutter 34 is positioned at approximately the same vertical position as the lower end surface 38US of the upper decorative plate 38U. Here, the open state refers to a state in which the shutter 34 has moved even slightly in the opening direction Do from the closed state, even if the banknote deposit / withdrawal slot 14 is not fully open.

[0034] The shutter section 35 is provided with a first sensor light-emitting section 42, a first sensor first light-receiving section 44a, a first sensor second light-receiving section 44b, a second sensor light-emitting section 46, a second sensor first light-receiving section 48a, and a second sensor second light-receiving section 48b, which detect the state of the shutter 34. The first sensor light-emitting section 42, the first sensor first light-receiving section 44a, the first sensor second light-receiving section 44b, the second sensor light-emitting section 46, the second sensor first light-receiving section 48a, and the second sensor second light-receiving section 48b are optical sensors.

[0035] The first sensor light emitter 42 is attached to the rear side of the left decorative panel 38L at a location very close to the upper end surface 38DS in the vertical direction (shutter movement direction), and emits (i.e., emits) detection light L1 toward the right so as to intersect with the movement path of the shutter 34.

[0036] The first sensor first light receiving unit 44a is attached to the rear side of the right side decorative panel 38R at the same position as the first sensor light emitting unit 42 in the vertical direction, and receives the detection light L1 emitted from the first sensor light emitting unit 42 and passing on the closing direction Dc side of the shutter 34 in the open state (i.e., the detection light L1 is incident).

[0037] The first sensor second light receiving unit 44b is attached to the rear side of the left decorative panel 38L, closer to the opening direction Do than the first sensor light emitting unit 42 and the second sensor first light receiving unit 48a, and receives the detection light L1 emitted from the first sensor light emitting unit 42 and passing through the first sensor prism 50L (described later) in the closed state (Figure 5).

[0038] The second sensor light-emitting unit 46 is attached to the rear side of the right decorative panel 38R, closer to the opening direction Do than the first sensor first light-receiving unit 44a, and emits detection light L2 toward the left so as to intersect with the movement path of the shutter 34. Hereinafter, the detection lights L1 and L2 will also be collectively referred to as detection light L.

[0039] The second sensor first light receiving unit 48a is located at the same position as the second sensor light emitting unit 46 in the vertical direction on the rear side of the left decorative panel 38L, and is attached between the first sensor light emitting unit 42 and the first sensor second light receiving unit 44b, and receives the detection light L2 emitted from the second sensor light emitting unit 46 and passing on the closing direction Dc side of the shutter 34 in the open state.

[0040] The second sensor second light receiving unit 48b is attached on the rear side of the right side decorative panel 38R, closer to the opening direction Do than the second sensor light emitter 46, and closer to the opening direction Do than the first sensor second light receiving unit 44b in the vertical direction, and receives the detection light L2 emitted from the second sensor light emitter 46 and passing through the second sensor prism 50R (described later) in the closed state (Figure 5).

[0041] The first sensor prism 50L has a shape like a capital letter "U" rotated 90° counterclockwise when viewed from the front, and is embedded inside the end of the left end of the shutter 34 on the closing direction Dc side, allowing light to pass through while changing its direction of travel inside. The first sensor prism 50L has an entrance surface formed on the upper left side of the first sensor prism 50L, facing leftward, through which light enters, and is located at the end of the left end of the shutter 34 on the closing direction Dc side. The first sensor prism 50L also has an exit surface formed on the lower left side of the first sensor prism 50L, facing leftward, through which light exits, and is located closer to the opening direction Do than the entrance surface of the first sensor prism 50L at the left end of the shutter 34.

[0042] In the closed state (FIG. 5), the first sensor prism 50L has an incident surface facing the first sensor light-emitting unit 42 in the left-right direction, and an exit surface facing the first sensor second light-receiving unit 44b in the left-right direction. In the closed state (FIG. 5), the first sensor prism 50L receives the detection light L1 emitted from the first sensor light-emitting unit 42 to the right on the incident surface, and then bends the detection light L1 forward and leftward inside the first sensor prism 50L, so that the detection light L1 is emitted from the exit surface to the left and enters the first sensor second light-receiving unit 44b.

[0043] The second sensor prism 50R has a shape like a capital letter "U" rotated 90° clockwise when viewed from the front, and is embedded slightly closer to the opening direction Do than the end of the shutter 34 at the right end on the closing direction Dc side, allowing light to pass through while changing its direction of travel inside. The second sensor prism 50R has an entrance surface, which is formed on the upper right side of the second sensor prism 50R and faces right, and through which light enters, and is positioned slightly closer to the opening direction Do than the end of the shutter 34 at the closing direction Dc side. The second sensor prism 50R also has an exit surface, which is formed on the lower right side of the second sensor prism 50R and faces right, and through which light exits, and is positioned closer to the opening direction Do than the entrance surface of the second sensor prism 50R at the right end of the shutter 34.

[0044] In the closed state (FIG. 5), the second sensor prism 50R has an incident surface that faces the second sensor light emitter 46 in the left-right direction, and an exit surface that faces the second sensor second light receiver 48b in the left-right direction. In the closed state (FIG. 5), the second sensor prism 50R receives the detection light L2 emitted leftward from the second sensor light emitter 46 and bends the detection light L2 forward and then rightward inside the prism 50R, so that the detection light L2 is emitted rightward from the exit surface and enters the second sensor second light receiver 48b.

[0045] [4. When the shutter is closed normally] In this configuration, in the open state (fully open state) shown in FIG. 3, the detection light L1 emitted from the first sensor light-emitting unit 42 passes through the shutter 34 on the closing direction Dc side and enters the first sensor first light-receiving unit 44a. Therefore, the light reception result of the first sensor first light-receiving unit 44a is the OFF state (light-transmitting state). Furthermore, the detection light L2 emitted from the second sensor light-emitting unit 46 passes through the shutter 34 on the closing direction Dc side and enters the second sensor first light-receiving unit 48a. Therefore, the light reception result of the second sensor first light-receiving unit 48a is the OFF state (light-transmitting state). On the other hand, the detection light L1 is not incident on the first sensor second light-receiving unit 44b. Therefore, the light reception result of the first sensor second light-receiving unit 44b is the ON state (light-blocking state). Furthermore, the detection light L2 is not incident on the second sensor second light-receiving unit 48b. Therefore, the light reception result of the second sensor second light receiving portion 48b becomes the ON state (light blocking state).

[0046] When the shutter 34 moves in the closing direction Dc from the open state (fully open state) (FIG. 3) and immediately before it enters the closed state as shown in FIG. 4, the detection light L1 emitted from the first sensor light emitter 42 passes through the shutter 34 on the closing direction Dc side and enters the first sensor first light receiver 44a. Therefore, the light reception result of the first sensor first light receiver 44a remains in the OFF state (light-transmitting state). Meanwhile, the detection light L2 emitted from the second sensor light emitter 46 is blocked by the shutter 34 and does not enter the second sensor first light receiver 48a. Therefore, the light reception result of the second sensor first light receiver 48a changes from the OFF state (light-transmitting state) to the ON state (light-blocking state). Meanwhile, the detection light L1 is not incident on the first sensor second light receiver 44b. Therefore, the light reception result of the first sensor second light receiver 44b remains in the ON state (light-blocking state). Further, the detection light L2 is not incident on the second sensor second light receiving portion 48b, so the light reception result of the second sensor second light receiving portion 48b remains in the ON state (light-blocking state).

[0047] When the shutter 34 moves further in the closing direction Dc from the state shown in FIG. 4 to the closed state shown in FIG. 5, the detection light L1 emitted from the first sensor light emitter 42 passes through the first sensor prism 50L and enters the first sensor second light receiver 44b. As a result, the light reception result of the first sensor second light receiver 44b changes from the ON state (light-blocking state) to the OFF state (light-transmitting state). Similarly, the detection light L2 emitted from the second sensor light emitter 46 passes through the second sensor prism 50R and enters the second sensor second light receiver 48b. As a result, the light reception result of the second sensor second light receiver 48b changes from the ON state (light-blocking state) to the OFF state (light-transmitting state). Meanwhile, the detection light L1 is not incident on the first sensor first light receiver 44a. As a result, the light reception result of the first sensor first light receiver 44a changes from the OFF state (light-transmitting state) to the ON state (light-blocking state). Further, the detection light L2 is not incident on the second sensor first light receiving portion 48a, so the light reception result of the second sensor first light receiving portion 48a remains in the ON state (light-blocking state).

[0048] In this way, when the shutter 34 moves from the fully open state in the closing direction Dc to the closed state while in the open state, first, the light reception result of the second sensor first light receiving portion 48a changes from the OFF state (light transmitting state) to the ON state (light blocking state). Next, the light reception result of the first sensor first light receiving portion 44a changes from the OFF state (light transmitting state) to the ON state (light blocking state). Finally, when the shutter 34 enters the closed state, the light reception results of the first sensor second light receiving portion 44b and the second sensor second light receiving portion 48b change from the ON state (light blocking state) to the OFF state (light transmitting state).

[0049] [5. Regarding foreign object entrapment] On the other hand, a foreign object trapped state in which a foreign object FS is trapped between the shutter 34 and the upper decorative plate 38U during the transition from the open state (FIG. 3) to the closed state (FIG. 5) will be described.

[0050] [5-1. Detection of foreign object trapped on the right side] 6 shows a state in which the left end of the shutter 34 on the closing direction Dc side reaches the lower end surface 38US of the upper decorative plate 38U in the vertical direction as in the closed state, but a foreign object FS is caught near the right end between the shutter 34 and the lower end surface 38US. Note that the lower decorative plate 38D is not shown in FIGS. 6, 7, and 8.

[0051] In this state, the detection light L1 emitted from the first sensor light emitter 42 passes through the first sensor prism 50L and enters the first sensor second light receiver 44b. Therefore, the light reception result of the first sensor second light receiver 44b is the OFF state (light-transmitting state). Note that depending on the position of the shutter 34, the detection light L1 emitted from the first sensor light emitter 42 may not enter the first sensor prism 50L and therefore the first sensor second light receiver 44b. On the other hand, because the incident surface of the second sensor prism 50R is located closer to the opening direction Do than the second sensor light emitter 46, the detection light L2 emitted from the second sensor light emitter 46 does not enter the second sensor prism 50R. Therefore, the light reception result of the second sensor second light receiver 48b is the ON state (light-blocking state). Furthermore, the detection light L1 is not incident on the first sensor first light receiver 44a. Therefore, the light reception result of the first sensor first light receiving section 44a is the ON state (light-blocking state). Furthermore, the detection light L2 is not incident on the second sensor first light receiving section 48a. Therefore, the light reception result of the second sensor first light receiving section 48a is the ON state (light-blocking state).

[0052] Thus, in the case of a foreign object pinched on the right side, the light reception result of the first sensor second light receiving unit 44b may be in the OFF state (light-transmitting state), but the light reception result of the second sensor second light receiving unit 48b will be in the ON state (light-blocking state), not the OFF state (light-transmitting state). When a light reception result of the ON state (light-blocking state) is obtained from at least one of the first sensor second light receiving unit 44b or the second sensor second light receiving unit 48b, the change control unit 21 determines that a foreign object pinched state has occurred. In this case, the change control unit 21 moves the shutter 34 in the opening direction Do to eliminate the pinched foreign object FS.

[0053] [5-2. Detection of foreign object trapped on the left side] Figure 7 shows a state in which a foreign object is trapped on the left side, in which the end of the right end of the shutter 34 on the closing direction Dc side reaches the lower end surface 38US of the upper decorative panel 38U in the vertical direction as in the closed state, but a foreign object FS is trapped near the left end between the shutter 34 and the lower end surface 38US.

[0054] In this state, the detection light L2 emitted from the second sensor light-emitting unit 46 passes through the second sensor prism 50R and enters the second sensor second light-receiving unit 48b. Therefore, the light-receiving result of the second sensor second light-receiving unit 48b is the OFF state (light-transmitting state). Note that, depending on the position of the shutter 34, the detection light L2 emitted from the second sensor light-emitting unit 46 may not enter the second sensor prism 50R and therefore may not enter the second sensor second light-receiving unit 48b. On the other hand, because the incident surface of the first sensor prism 50L is located closer to the opening direction Do than the first sensor light-emitting unit 42, the detection light L1 emitted from the first sensor light-emitting unit 42 does not enter the first sensor prism 50L. Therefore, the light-receiving result of the first sensor second light-receiving unit 44b is the ON state (light-blocking state). Furthermore, the detection light L1 emitted from the first sensor light-emitting unit 42 is blocked by the shutter 34 or the foreign object FS and does not enter the first sensor first light-receiving unit 44a. Therefore, the light reception result of the first sensor first light-receiving unit 44a is the ON state (light-blocking state). Furthermore, the detection light L2 is not incident on the second sensor first light-receiving unit 48a. Therefore, the light reception result of the second sensor first light-receiving unit 48a is the ON state (light-blocking state).

[0055] Thus, in the case of a foreign object being pinched on the left side, the light reception result of the second sensor second light receiving unit 48b may be in the OFF state (light-transmitting state), but the light reception result of the first sensor second light receiving unit 44b will be in the ON state (light-blocking state), and will not be in the OFF state (light-transmitting state). Thus, when a light reception result in the ON state (light-blocking state) is obtained from at least one of the first sensor second light receiving unit 44b or the second sensor second light receiving unit 48b, the change control unit 21 determines that a foreign object has been pinched. In this case, the change control unit 21 moves the shutter 34 in the opening direction Do to eliminate the pinching of the foreign object FS.

[0056] [5-3. Detecting foreign objects trapped in the center] Figure 8 shows a state in which a foreign object FS is sandwiched in the center between the shutter 34 and the lower end surface 38US of the upper decorative panel 38U in the left-right direction, and neither the left nor right end of the shutter 34 on the closing direction Dc side has reached the lower end surface 38US of the upper decorative panel 38U in the up-down direction, as in the closed state.

[0057] In this state, if the detection light L1 emitted from the first sensor light-emitting unit 42 is blocked by a foreign object FS, it does not enter the first sensor first light-receiving unit 44a. Therefore, the light-receiving result of the first sensor first light-receiving unit 44a is the ON state (light-blocking state). Furthermore, the detection light L2 emitted from the second sensor light-emitting unit 46 is blocked by the shutter 34 and does not enter the second sensor first light-receiving unit 48a. Therefore, the light-receiving result of the second sensor first light-receiving unit 48a is the ON state (light-blocking state). Meanwhile, because the incident surface of the first sensor prism 50L is located closer to the opening direction Do than the first sensor light-emitting unit 42, the detection light L1 emitted from the first sensor light-emitting unit 42 does not enter the first sensor second light-receiving unit 44b. Therefore, the light-receiving result of the first sensor second light-receiving unit 44b is the ON state (light-blocking state). Furthermore, because the incident surface of the second sensor prism 50R is located closer to the opening direction Do than the second sensor light emitter 46, the detection light L2 emitted from the second sensor light emitter 46 does not enter the second sensor second light receiver 48b. Therefore, the light reception result of the second sensor second light receiver 48b is the ON state (light-blocking state).

[0058] In this way, when a foreign object is pinched in the center, the light reception results of both the first sensor second light receiving unit 44b and the second sensor second light receiving unit 48b are ON (light-blocking state), not OFF (light-transmitting state). In this way, when a light reception result of ON (light-blocking state) is obtained from at least one of the first sensor second light receiving unit 44b or the second sensor second light receiving unit 48b, the change control unit 21 determines that a foreign object is pinched. In this case, the change control unit 21 moves the shutter 34 in the opening direction Do to eliminate the pinched foreign object FS.

[0059] On the other hand, if the detection light L1 emitted from the first sensor light-emitting unit 42 is not blocked by the foreign object FS, the detection light L1 passes through the shutter 34 on the closing direction Dc side and enters the first sensor first light-receiving unit 44a. Therefore, the light-receiving result of the first sensor first light-receiving unit 44a becomes the OFF state (light-transmitting state). In contrast, if the light-receiving result of the first sensor first light-receiving unit 44a remains in the OFF state (light-transmitting state) even after a predetermined time has elapsed since the shutter 34 started to move from the fully open state toward the closing direction Dc, the change control unit 21 determines that a foreign object has been trapped. In this case, the change control unit 21 moves the shutter 34 in the opening direction Do to eliminate the trapped foreign object FS.

[0060] [5-4. Detecting a soft foreign object] On the other hand, if a soft, crushable foreign object FS is sandwiched between the shutter 34 and the lower end surface 38US of the upper decorative panel 38U, the shutter 34 will be closed, but the foreign object FS will remain sandwiched between the shutter 34 and the lower end surface 38US of the upper decorative panel 38U in the closed state.

[0061] In this case, as the shutter 34 moves in the closing direction Dc and approaches the closed state, the light reception result of the first sensor first light receiving portion 44a changes from the OFF state (light-transmitting state) to the ON state (light-blocking state), and then the shutter 34 moves further in the closing direction Dc while crushing the foreign object FS. At this time, the shutter 34 moves in the closing direction Dc while crushing the foreign object FS, so the moving speed is slower than usual. Subsequently, when the shutter 34 reaches the closed state while still holding the foreign object FS, the light reception results of the first sensor second light receiving portion 44b and the second sensor second light receiving portion 48b change from the ON state (light-blocking state) to the OFF state (light-transmitting state).

[0062] In contrast, if the time from when the light reception result of the first sensor first light receiving unit 44a changes from the OFF state (light transmitting state) to the ON state (light blocking state) until the light reception results of the first sensor second light receiving unit 44b and the second sensor second light receiving unit 48b change from the ON state (light blocking state) to the OFF state (light transmitting state) is longer than a predetermined threshold, the change control unit 21 determines that the shutter 34 has become closed with the foreign object FS trapped. In this case, the change control unit 21 moves the shutter 34 in the opening direction Do to eliminate the trapping of the foreign object FS.

[0063] [6. Effects, etc.] In the above configuration, the banknote deposit and withdrawal device 11 has a first sensor light-emitting unit 42 that emits detection light L1 to the right side on the left side of the shutter 34, and a second sensor light-emitting unit 46 that emits detection light L2 to the left side on the right side of the shutter 34, a first sensor prism 50L that passes detection light L1 on the left side of the shutter 34, and a second sensor prism 50R that passes detection light L2 on the right side of the shutter 34, and a first sensor second light-receiving unit 44b that receives detection light L1 that has passed through the first sensor prism 50L on the left side of the shutter 34, and a second sensor second light-receiving unit 48b that receives detection light L2 that has passed through the second sensor prism 50R on the right side of the shutter 34.

[0064] Furthermore, when the light reception results of the first sensor second light receiving unit 44b and the second sensor second light receiving unit 48b are in the OFF state (light transmitting state), the banknote deposit and withdrawal device 11 determines that the shutter 34 has entered the closed state without pinching a foreign object FS. Therefore, even if a foreign object right-side pinching state or a foreign object left-side pinching state occurs and the shutter 34 tilts, the banknote deposit and withdrawal device 11 can detect that a foreign object pinching state has occurred without erroneously recognizing that the shutter 34 is in the closed state. This makes it possible for the banknote deposit and withdrawal device 11 to prevent the operation of closing the shutter 34 from being completed while a foreign object is still pinched.

[0065] Furthermore, the banknote deposit and withdrawal device 11 is arranged so that the first sensor first light receiving unit 44a, which serves as a third light receiving unit that receives detection light L1 that has passed through the closing direction Dc more than the shutter 34, is located to the right of the shutter 34 so as to face the first sensor light emitting unit 42 in the left-right direction, and the second sensor first light receiving unit 48a, which serves as a fourth light receiving unit that receives detection light L2 that has passed through the closing direction Dc more than the shutter 34, is located to the left of the shutter 34 so as to face the second sensor light emitting unit 46 in the left-right direction.

[0066] Furthermore, if the banknote deposit and withdrawal device 11 obtains a light receiving result of OFF state (light transmitting state) from the first sensor first light receiving unit 44a even after a predetermined time has elapsed since the shutter 34 started to move from the fully open state toward the closing direction Dc, it determines that a foreign object has been trapped.

[0067] Furthermore, if the time from when the light reception result of the first sensor first light receiving unit 44a changes from the OFF state (light transmitting state) to the ON state (light blocking state) until the light reception results of the first sensor second light receiving unit 44b and the second sensor second light receiving unit 48b change from the ON state (light blocking state) to the OFF state (light transmitting state) is longer than a predetermined threshold, the banknote deposit and withdrawal device 11 determines that the shutter 34 has entered the closed state with the foreign object FS trapped. Therefore, even if the shutter 34 has entered the closed state, the banknote deposit and withdrawal device 11 can recognize that a soft and easily crushed foreign object FS has been trapped.

[0068] According to the above configuration, the banknote deposit and withdrawal device 11 comprises the shutter 34 that opens and closes the banknote deposit and withdrawal slot 14 as an opening, the change control unit 21 that opens and closes the banknote deposit and withdrawal slot 14 by moving the shutter 34 in a shutter movable direction as a first direction, the first sensor light-emitting unit 42 that is provided on the left side of the shutter 34 in one direction in the left-right direction as a second direction intersecting with the shutter movable direction and emits detection light L1 as a first light to the right side that is the other direction in the left-right direction, the second sensor light-emitting unit 46 that is provided on the right side of the shutter 34 and emits detection light L2 as a second light to the left, and the second sensor light-emitting unit 46 that is provided on the left side of the shutter 34 and emits detection light L1 as a second light to the left. The shutter 34 is provided with a first sensor prism 50L that passes detection light L1, a second sensor prism 50R that is provided on the right side of the shutter 34 and passes detection light L2, a first sensor second light receiving unit 44b that is provided on the left side of the shutter 34 and receives detection light L1 that has passed through the first sensor prism 50L, and a second sensor second light receiving unit 48b that is provided on the right side of the shutter 34 and receives detection light L2 that has passed through the second sensor prism 50R, and the change control unit 21 determines that the shutter 34 is in a closed state when it obtains a detection result of the first sensor second light receiving unit 44b receiving detection light L1 and a detection result of the second sensor second light receiving unit 48b receiving detection light L2.

[0069] As a result, when the shutter 34 is tilted just before closing, the banknote deposit and withdrawal device 11 will not receive the detection light L from either the first sensor second light receiving unit 44b or the second sensor second light receiving unit 48b, which are located respectively to the left and right of the shutter 34, and will therefore be able to recognize that a foreign object FS is trapped and that the shutter 34 is not properly closed.

[0070] 7. Other Embodiments In the above-described embodiment, the banknote deposit and withdrawal device 11 has been described as determining that the shutter 34 is in the closed state when the light reception results of the first sensor second light receiving unit 44b and the second sensor second light receiving unit 48b are in the OFF state (light-transmitting state).

The present invention is not limited to this, and the banknote deposit and withdrawal device 11 may cause the detection light L2 emitted from the second sensor light-emitting unit 46 provided to the right of the shutter 34 to pass through a prism that is continuously formed inside the shutter 34 from the right side surface to the left side surface of the shutter 34, and to be incident on the second sensor second light-receiving unit 48b provided to the left of the shutter 34, opposite the second sensor light-emitting unit 46 in the left-right direction.

[0074] Furthermore, in the above-described embodiment, the banknote deposit and withdrawal device 11 has been described as being arranged on the side in the opening direction Do of the first sensor prism 50L.

[0076] Furthermore, in the above-described embodiment, the banknote deposit and withdrawal device 11 has described a case in which, if the time from when the light reception result of the first sensor first light receiving unit 44a changes from the OFF state (light-transmitting state) to the ON state (light-blocking state) until the light reception result of the first sensor second light receiving unit 44b and the second sensor second light receiving unit 48b changes from the ON state (light-blocking state) to the OFF state (light-transmitting state) is longer than a predetermined threshold, it is determined that the shutter 34 has entered a closed state while the foreign object FS is still trapped. The present invention is not limited to this, and the banknote deposit and withdrawal device 11 may determine that the shutter 34 has entered a closed state while the foreign object FS is still trapped if the amount of rotation of the shutter drive motor from when the light reception result of the first sensor first light receiving unit 44a changes from an OFF state (light-transmitting state) to an ON state (light-blocking state) until the light reception results of the first sensor second light receiving unit 44b and the second sensor second light receiving unit 48b change from an ON state (light-blocking state) to an OFF state (light-transmitting state) is longer than a predetermined threshold.
