Description

[Technical Field]

[0001] The present invention relates to a currency handling device. [Background technology]

[0002] For example, among currency handling devices such as automated teller machines, there are known ones that include a mounting section to which a currency handling unit is detachably attached, and a device housing having an inlet for inserting currency into the currency handling unit attached to the mounting section. This type of currency handling device includes a shutter mechanism provided in the device housing having a main body shutter that opens and closes the inlet, and the inlet that opens when the currency handling unit is pulled out of the mounting section is closed by the main body shutter of the shutter mechanism. In this currency handling device, the inlet is closed by the currency handling unit when the currency handling unit is attached to the mounting section.

[0003] In a currency handling device of related art, a currency handling unit is detachably attached to the front and rear of the device housing, and a main body shutter that opens and closes the deposit slot is supported so as to be openable and closable by a hinge portion located on the front side of the device housing at the deposit slot (Patent Document 1). The main body shutter of the shutter mechanism retracts from a closed position that closes the deposit slot to an open position that opens the deposit slot by tilting downward via the hinge portion toward the rear side of the device housing relative to the deposit slot. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2013-50769 Summary of the Invention [Problem to be solved by the invention]

[0005] As described above, the shutter mechanism of the currency handling device in Patent Document 1 opens the slot by the main body shutter, which has closed the slot, tilting downward via the hinge toward the rear side of the device housing. Therefore, to avoid a collision between the main body shutter, which is retracting from the slot toward the rear side of the device housing, and the currency handling unit, which is entering the mounting section from the rear side toward the front side of the device housing, the slot is closed by the currency handling unit after the main body shutter has retracted from the slot.

[0006] Therefore, in this currency handling device, there is a period of time when the entire slot is open, from when the main body shutter opens the slot until the currency handling unit attached to the mounting section closes it. As a result, there is a risk that a user may accidentally insert a coin or a finger into the slot, which is open when the currency handling unit is attached or detached. In this case, there is the inconvenience that the coin inserted into the slot will not be inserted into the currency handling unit but will fall inside the device housing.

[0007] To address this issue, a structure has been proposed in which the main body shutter retracts from the insertion port toward the front of the device housing when it rotates from the closed position to the open position. In this structure, the shutter mechanism has a support arm that supports the main body shutter and is rotatable, and a locking member that is movable between a locking position that locks the main body shutter in the closed position and an unlocking position that releases the locked state of the main body shutter, and the locking member is positioned so that it engages with the support arm from the front of the device housing.

[0008] However, with the above-mentioned structure, for example, if the main body shutter, which is in the open position inside the slot, is pressed by a hand inserted into the slot, the locking member may move to the locked position before the main body shutter can rotate from the open position to the closed position. In this case, the support arm supporting the main body shutter as it rotates toward the closed position comes into contact with the locking member in the locked position, preventing the main body shutter from rotating. As a result, the main body shutter stops midway through its rotation from the open position to the closed position, making it impossible to close the slot.

[0009] The disclosed technology has been developed in consideration of the above, and aims to provide a currency handling device in which the rotation of the main body shutter is not hindered by the locking member, and the main body shutter can be rotated to the closed position, even when the main body shutter rotates from the open position to the closed position after the locking member has moved to the locked position. [Means for solving the problem]

[0010] One aspect of the currency handling device disclosed in the present application includes a currency handling unit, an attachment section to which the currency handling unit is attached and detached, a device housing provided with an inlet for inserting currency into the currency handling unit attached to the attachment section, and a shutter mechanism provided in the device housing having a main body shutter that rotates between a closed position that closes the inlet and an open position that opens the inlet, wherein the currency handling unit is attached and detached to and from the attachment section along the front-to-rear direction of the device housing, and the main body shutter rotates from the closed position to the open position. the shutter mechanism has a support member that supports the main body shutter and rotates together with the main body shutter, a locking member that is provided so as to be movable between a locking position that locks the main body shutter at the closed position and an unlocking position that unlocks the main body shutter, and a rotating member that is provided so as to be rotatable on the support member and that engages with the locking member at the locking position, and the locking member is disposed so as to engage with the rotating member from the front side of the device housing, Normally, the locking member moves to the locking position after the main body shutter has rotated from the open position to the closed position, After the locking member has moved to the locking position, the main body shutter has rotated from the open position to the closed position. In the case The locking member, which is positioned at the locking position, comes into contact with the rotating member, and the rotating member is rotated by the locking member, thereby rotating the main body shutter to the closing position. [Effects of the Invention]

[0011] According to one aspect of the currency handling device disclosed in the present application, even when the main body shutter rotates from the open position to the closed position after the locking member has moved to the locked position, the rotation of the main body shutter is not hindered by the locking member, and the main body shutter can be rotated to the closed position.

[0013] Hereinafter, embodiments of a currency handling device disclosed in the present application will be described in detail with reference to the accompanying drawings. However, the currency handling device disclosed in the present application is not limited to the following embodiments. [Example]

[0014] (Currency handling equipment) Fig. 1 is a perspective view showing the entire currency handling device of the embodiment. In Fig. 1, the front-to-rear direction of the currency handling device is the X direction, the width direction is the Y direction, and the height direction is the Z direction. In Fig. 1 and subsequent figures, the X, Y, and Z directions are indicated in the same manner as in Fig. 1.

[0015] 1, the currency handling device 1 includes a currency handling unit 3, a unit mounting section 5 to which the currency handling unit 3 is detachably attached, and a device housing 6 provided with a deposit section 7 having an inlet 7a for depositing currency. The currency handling device 1 of the embodiment also includes a shutter mechanism 8 for closing the inlet 7a, which is opened when the currency handling unit 3 is detached from the unit mounting section 5.

[0016] The currency handling unit 3 is detachably attached to the unit mounting section 5 along the X direction, which is the front-to-rear direction of the device housing 6, and is pulled out from the rear surface 6R of the device housing 6 with respect to the unit mounting section 5. As will be described in detail later, the currency handling unit 3 has a unit shutter 22 that opens and closes a receiving opening 21 corresponding to the insertion opening 7a of the deposit section 7.

[0017] The front 6F side of the device housing 6 at the top of the unit mounting section 5 is connected to the deposit port 7a of the deposit section 7, and when the currency handling unit 3 is mounted on the unit mounting section 5, the deposit port 7a is closed by the unit shutter 22 of the currency handling unit 3.

[0018] The deposit unit 7 is provided on the front surface 6F of the device housing 6, and has an inlet 7a for depositing money into the money handling unit 3 attached to the unit mounting part 5. The inlet 7a of the deposit unit 7 is opened and closed by the unit shutter 22 of the money handling unit 3 attached to the unit mounting part 5. The deposit unit 7 handles, for example, coins inserted through the inlet 7a, but may also handle banknotes or both coins and banknotes. The deposit unit 7 may also be used as a deposit / withdrawal unit that also dispenses money to users.

[0019] An operation panel 11, a card insertion slot 12, a bankbook insertion slot 13, a handset 14, etc. are provided on the front surface 6F of the device housing 6. An opening / closing door 15 for opening and closing the inside of the device housing 6 is provided on the rear surface 6R of the device housing 6.

[0020] Details will be provided later, but the shutter mechanism 8 is provided in the deposit section 7 of the device housing 6, and when the currency handling unit 3 is removed from the unit mounting section 5, the safety shutter 31, which serves as the main body shutter, closes the deposit slot 7a, preventing users from accidentally depositing coins or their fingertips into the deposit slot 7a.

[0021] (Currency Handling Unit) Fig. 2 is a perspective view showing the currency handling unit 3 included in the currency handling device 1 of the embodiment. As shown in Fig. 2, the currency handling unit 3 includes a receiving opening 21 corresponding to the insertion opening 7a of the deposit unit 7, a unit shutter 22 that opens and closes the receiving opening 21, an opening / closing mechanism 23 that opens and closes the unit shutter 22, and a storage unit 24 that stores currency that has passed through the receiving opening 21.

[0022] The receiving opening 21 of the currency handling unit 3 is formed to overlap the inlet 7a in the XY plane when the currency handling unit 3 is attached to the unit attachment section 5. The unit shutter 22 is formed in a flat plate shape, and is provided so as to be slidable in the X direction relative to the receiving opening 21, for example.

[0023] In addition, a shutter operating member 26 for operating the shutter mechanism 8 is provided on the front surface 6F side of the device housing 6 on the side surface 3S of the currency handling unit 3. The shutter operating member 26 has an unlocking portion 27 for unlocking the locked state of a locking member 45 (described later) in the shutter mechanism 8, and an operating portion 28 for rotating a safety shutter 31 (described later) in the shutter mechanism 8.

[0024] The shutter operating member 26 is formed in an elongated shape extending in the X direction, with one end 26a protruding from the currency handling unit 3 toward the front surface 6F of the device housing 6 and the other end 26b fixed to the side surface 3S of the currency handling unit 3. The shutter operating member 26 advances and retreats relative to the shutter mechanism 8 as the currency handling unit 3 is attached to and detached from the unit mounting section 5.

[0025] The unlocking portion 27 of the shutter operating member 26 is formed extending from the tip of one end 26a of the shutter operating member 26 along the lower end, and has an inclined surface 27a inclined with respect to the X direction, and a flat surface 27b formed along the X direction.

[0026] The actuating portion 28 of the shutter operating member 26 is formed on the upper part of the other end 26b side of the shutter operating member 26, and has an actuating surface 28a that is inclined with respect to the Z direction. The actuating surface 28a is inclined so that its upper end is located closer to the front surface 6F of the device housing 6 than its lower end.

[0027] (shutter mechanism) Fig. 3 is a perspective view showing the shutter mechanism 8 provided in the currency handling device 1 of the embodiment. Fig. 4 is a perspective view showing the inside of the shutter mechanism 8 in the embodiment. Fig. 5 is an exploded perspective view showing the shutter mechanism 8 in the embodiment.

[0028] As shown in Figures 3, 4 and 5, the shutter mechanism 8 has a safety shutter 31 that opens and closes the deposit slot 7a depending on the attachment and detachment of the currency handling unit 3 to the unit mounting section 5, a support stay 32 as a support member that supports the safety shutter 31, a set of support arms 33A, 33B (hereinafter also referred to as support arms 33) as support members that support the safety shutter 31 via the support stay 32, and a base member 34 that rotatably supports the set of support arms 33A, 33B via a pivot shaft 35.

[0029] The shutter mechanism 8 also has a tension coil spring 36 that biases the support arm 33 so that the safety shutter 31 closes the deposit port 7a, and an opening / closing roller 37 that is operated by the shutter operating member 26 of the currency handling unit 3 to open and close the safety shutter 31.

[0030] The safety shutter 31 has a substantially rectangular flat surface 31a that closes the insertion port 7a, and a set of mounting legs 31b that support the flat surface 31a. A sign such as "Preparation in Progress" is provided on the flat surface 31a to alert the user. The set of mounting legs 31b is fixed to the upper surface of the support stay 32 with fixing screws 38.

[0031] 3 and 4, the safety shutter 31 rotates between a closed position P1 where the insertion port 7a is closed and an open position P2 where the insertion port 7a is opened, as a result of the pair of support arms 33 rotating about a rotation shaft 35. At the closed position P1, the safety shutter 31 is oriented such that the flat portion 31a is aligned with the XY plane. At the open position P2, the safety shutter 31 is oriented such that the flat portion 31a is inclined with respect to the XY plane (see FIG. 9).

[0032] 3, 4 and 5, the support stay 32 is provided along the Y direction, and an opening / closing roller 37 is rotatably provided at the end on the side where the shutter operating member 26 advances and retreats relative to the shutter mechanism 8. A bearing portion 32a that supports a rotation shaft 37a of the opening / closing roller 37 along the Y direction is formed on the support stay 32, and the opening / closing roller 37 is supported on the rotation shaft 37a. Therefore, the opening / closing roller 37 moves together with the safety shutter 31, which rotates via a pair of support arms 33A and 33B.

[0033] The pair of support arms 33A, 33B are fixed to both ends of the support stay 32, and are each rotatably supported on the base member 34 via a rotation shaft 35. Therefore, the support stay 32, which serves as a support member supporting the safety shutter 31, and the pair of support arms 33A, 33B rotate together with the safety shutter 31 relative to the base member 34. One of the support arms, 33A, is formed with a spring hook 33b to which one end of a tension coil spring 36 is attached.

[0034] The base member 34 has a base portion 40 fixed to the device housing 6, a pair of support walls 41A, 41B that rotatably support a pair of support arms 33A, 33B, and a guide wall 43 that supports a locking member 45, which will be described later. The base portion 40 is fixed to a frame (not shown) on the front surface 6F side of the device housing 6 with fixing screws 38. The guide wall 43 has a spring hook 43a to which the other end of the tension coil spring 36 is attached. The guide wall 43 will be described in detail later.

[0035] The tension coil spring 36 is a spring that rotates the safety shutter 31, and has one end attached to the spring hook 33b of the support arm 33A and the other end attached to the spring hook 43a of the base member 34. Therefore, the tension coil spring 36 biases the support arm 33A so that the safety shutter 31 rotates toward the closed position P1.

[0036] The opening / closing roller 37 is rotatably supported by the support stay 32 via a rotary shaft 37a, and is disposed on the movement path of the operating portion 28 of the shutter operating member 26 that moves along the X direction.

[0037] (Main part of the shutter mechanism) The shutter mechanism 8 also has a locking member 45 that locks the safety shutter 31 in the closed position P1, a locking tension coil spring 46 that urges the locking member 45 in the direction that locks the safety shutter 31, and an unlocking roller 47 that releases the locked state of the locking member 45.

[0038] Fig. 6 is a perspective view showing the main parts of the shutter mechanism 8 in this embodiment. As shown in Figs. 5 and 6, the shutter mechanism 8 has a rotating member 48 with which the locking member 45 engages when locking the safety shutter 31, and a stopper member 49 that restricts the rotation range of the rotating member 48.

[0039] 3, 4, and 5, a guide shaft 43b that supports a locking member 45 is provided on the guide wall 43 of the base member 34, and the locking member 45 is provided so as to be slidable along the guide wall 43. In addition, a rotating member 48 is rotatably provided on the support stay 32 that supports the safety shutter 31. The rotating member 48 will be described in detail later.

[0040] The locking member 45 is provided so as to be movable between a locking position P3 where the safety shutter 31 is locked at the closed position P1 and a release position P4 where the safety shutter 31 is released from the locked state.

[0041] The locking member 45 has an elongated guide hole 45a supported by the guide shaft 43b of the guide wall 43, a locking claw 45b that engages with the rotating member 48, a roller support piece 45c that supports the unlocking roller 47, and a spring hook piece 45d to which one end of the locking tension coil spring 46 is attached.

[0042] The locking claw 45b is formed on the upper end of the locking member 45 and engages with the rotating member 48. When the locking member 45 moves along the longitudinal direction of the guide hole 45a through which the guide shaft 43b is passed, the locking claw 45b advances and retreats relative to the rotating member 48. The roller support piece 45c is formed by bending the lower end of the locking member 45 toward the guide wall 43. The spring hook piece 45d is formed on the roller support piece 45c.

[0043] Furthermore, the locking member 45 is disposed on the front surface 6F side of the device housing 6 relative to the support arm 33A, and is configured so that the locking claw 45b engages with the rotating member 48 on the side to which the support arm 33A rotates when the safety shutter 31 opens the insertion slot 7a. In other words, the locking member 45 is disposed so as to engage with the rotating member 48 from the front surface 6F side of the device housing 6. This ensures the reliability of the locked state in which the locking member 45 prevents the safety shutter 31 from rotating, even if, for example, a user presses the flat surface portion 31a of the safety shutter 31 in the closed position P1 and an external force is applied that rotates the safety shutter 31 from the closed position P1 to the open position P2.

[0044] One end of the tension coil spring 46 for locking is attached to a spring hook 45d of the locking member 45, and the other end is attached to a spring hook 43c formed on the guide wall 43 of the base member 34. Therefore, the tension coil spring 46 biases the locking member 45 so that the locking claw 45b engages with the rotating member 48.

[0045] The unlocking roller 47 is rotatably supported by a roller support piece 45c of the locking member 45 via a rotation shaft 47a and is disposed on the movement path of the unlocking portion 27 of the shutter operating member 26 which moves in the X direction. In addition, a notch 43d is formed in the guide wall 43 of the base portion 34 to avoid interference with the unlocking roller 47 of the locking member 45 when the locking claw 45b is retracted from the rotating member 48.

[0046] As shown in Figures 5 and 6, the rotating member 48 is rotatably mounted on the bearing portion 32a of the support stay 32, and is positioned so as to engage with the locking member 45 when the locking member 45 moves to the locking position P3.

[0047] The rotating member 48 has a rotating piece 48a that is rotatably supported by the support stay 32, and an engaging piece 48b that engages with the locking claw 45b of the locking member 45. The rotating piece 48a is provided along the end surface of the end of the support stay 32 in the Y direction. The rotating piece 48a has a rotating hole 48c through which the bearing portion 32a is passed, and is provided rotatably along the outer peripheral surface of the bearing portion 32a.

[0048] As will be described later, the rotating member 48 is configured so that, after being rotated by the locking member 45, the rotating member 48 rotates by its own weight and returns to an initial position where it engages with the locking claw 45b of the locking member 45. The rotating member 48 is also disposed so as to rest on the connecting portion 39 of the support arm 33A, and the rotation position of the rotating member 48 is restricted by the connecting portion 39 so that, in the initial position of the rotating member 48, the locking member 45, which is located at the locking position P3, engages with the engagement piece 48b.

[0049] The engagement piece 48b is bent toward the locking member 45 with respect to the rotating piece 48a and extends in the Y direction. An engagement surface 48d with which the locking claw 45b of the locking member 45 engages is formed on the engagement piece 48b on the front surface 6F side of the device housing 6. Furthermore, an actuation surface 48e with which the upper end of the locking claw 45b of the locking member 45 contacts when the rotating member 48 is rotated by the locking member 45 is formed on the opposite side of the engagement surface 48d, i.e., on the rear surface 6R side of the device housing 6. Since the front and back surfaces of the engagement piece 48b function as the engagement surface 48d and the actuation surface 48e, respectively, the shape of the rotating member 48 can be simplified. As a result, the shutter mechanism 8 is prevented from becoming larger due to the rotating member 48.

[0050] Furthermore, the locking claw 45b of the locking member 45 engages with the engagement surface 48d of the engagement piece 48b of the rotating member 48, so that a larger engagement area for the locking claw 45b can be ensured compared to, for example, a structure in which the locking claw 45b engages with a part of the support arm 33A. This increases the stability of the engagement state between the locking claw 45b and the engagement surface 48d, and increases the reliability of the locked state of the safety shutter 31 by the locking member 45.

[0051] Furthermore, a connecting portion 39 that is connected to the end of the support stay 32 is formed by bending in the Y direction at the upper end of the support arm 33A. A notch 39a is formed in the connecting portion 39 at a portion that faces the engaging piece 48b of the rotating member 48. This notch 39a is formed merely for the purpose of adjusting the position of the engaging surface 48d of the engaging piece 48b relative to the locking claw 45b, and is not limited to a structure that has the notch 39a.

[0052] In this embodiment, the rotating member 48 is provided on the support stay 32, but the present invention is not limited to this structure. For example, if the end of the support stay 32 is formed by the support arm 33, the rotating member 48 may be provided on the support arm 33.

[0053] Furthermore, the locking member 45 is formed so that the tip of the locking claw 45b forms an acute angle, and the upper end of the locking member 45 is formed so as not to interfere with the operation of rotating the rotating member 48.

[0054] 6, an arc-shaped curved surface 45e that slides against the operating surface 48e of the rotating member 48 while rotating the rotating member 48 may be formed on the upper end of the locking member 45 at a portion that comes into contact with the operating surface 48e of the rotating member 48. This makes it easier for the operating surface 48e side of the engagement piece 48b of the rotating member 48 to move along the curved surface 45e of the locking member 45 while the upper end of the locking member 45 rotates the rotating member 48, and also makes it possible to reduce the amount of rotation of the rotating member 48 rotated by the locking member 45. This allows the locking member 45 to move more smoothly toward the front surface 6F of the device housing 6 relative to the rotating member 48.

[0055] The stopper member 49 has an attachment piece 49a attached to the support arm 33A, a fixed piece 49b fixed onto the connecting portion 39, a retaining piece 49c for maintaining the position of the rotating member 48, and a restricting piece 49d for restricting the rotation range of the rotating member 48. The stopper member 49 is formed by bending the attachment piece 49a, the fixed piece 49b, the retaining piece 49c, and the restricting piece 49d in this order in a stepped manner.

[0056] Mounting piece 49a is attached to the upper end of support arm 33A with fixing screw 50. Anti-slip piece 49c maintains the position of rotating member 48 so that rotating member 48 supported by bearing portion 32a does not fall off from bearing portion 32a. Restricting piece 49d restricts the rotation range of rotating member 48 by coming into contact with rotating member 48 when engaging piece 48b of rotating member 48 is rotated upward.

[0057] Furthermore, the restricting piece 49d of the stopper member 49 restricts the rotation range of the rotating member 48 so that, after the rotating member 48 is rotated by the locking member 45, the rotating member 48 returns by its own weight to the initial position where it engages with the locking member 45. This simplifies the rotation structure of the rotating member 48 and enables the rotated rotating member 48 to be stably returned to the initial position.

[0058] (Operation of the shutter mechanism) 7 to 10 are side views for explaining the operation of the currency handling unit 3 and the shutter mechanism 8 in the embodiment. Here, the operation of the shutter mechanism 8 when the currency handling unit 3 is attached to the unit attachment section 5 of the currency handling apparatus 1 will be explained.

[0059] First, as shown in Figure 7, when the currency handling unit 3 is removed from the unit mounting section 5, the shutter mechanism 8 has the safety shutter 31 in the closed position P1 closing the deposit slot 7a. At this time, the locking claw 45b of the locking member 45 is engaged with the engaging piece 48b of the rotating member 48, and the shutter mechanism 8 has the safety shutter 31 locked in the closed position P1. A user looking at the deposit section 7 can also see the safety shutter 31 closing the deposit slot 7a.

[0060] In addition, in the closed position P1, the flat surface 31a of the safety shutter 31 is slightly inclined toward the front surface 6F of the device housing 6, which increases the visibility of the display on the flat surface 31a from the user on the front surface 6F side. This makes it easier for the user to recognize that the deposit unit 7 cannot be used.

[0061] Next, when the currency handling unit 3 enters the unit mounting section 5 from the rear 6R side of the device housing 6 toward the front 6F side, and the unlocking section 27 of the shutter operating member 26 of the currency handling unit 3 enters the shutter mechanism 8, the inclined surface 27a of the unlocking section 27 comes into contact with the peripheral surface of the unlocking roller 47 (see Figure 7).

[0062] 8, as the currency handling unit 3 advances further toward the front surface 6F of the device housing 6 relative to the unit mounting portion 5, the unlocking portion 27 of the shutter operating member 26 moves, causing the unlocking roller 47 to roll downward along the inclined surface 27a of the unlocking portion 27 and reach the flat surface 27b. As the unlocking roller 47 moves along the inclined surface 27a of the unlocking portion 27 to the flat surface 27b, the locking member 45 slides downward along the guide wall 43 against the biasing force of the tension coil spring 46, the locking claw 45b disengages from the engaging piece 48b of the rotating member 48, and the locked state of the support arm 33A is released. As a result, in the shutter mechanism 8, the support arm 33A becomes rotatable, and the safety shutter 31 becomes rotatable from the closed position P1 toward the open position P2.

[0063] After the locking claw 45b of the locking member 45 disengages from the engaging piece 48b of the rotating member 48, the operating surface 28a of the operating portion 28 of the shutter operating member 26 comes into contact with the circumferential surface of the opening / closing roller 37, as shown in Fig. 8. Next, as the currency handling unit 3 advances further toward the front surface 6F of the device housing 6, the support arm 33A is pushed via the opening / closing roller 37 that is in contact with the operating portion 28 of the shutter operating member 26, and the opening / closing roller 37 rolls downward along the operating surface 28a of the operating portion 28, as shown in Fig. 9.

[0064] At this time, as the unlocking portion 27 of the shutter operating member 26 moves, the unlocking roller 47 rolls in the X direction along the flat surface 27b of the unlocking portion 27, thereby maintaining the unlocked state in which the locking claw 45b is retracted from the rotating member 48.

[0065] In the shutter mechanism 8, the support arm 33A is pushed by the operating portion 28 of the shutter operating member 26 and rotates around the rotation shaft 35 against the biasing force of the tension coil spring 36, causing the safety shutter 31 to start rotating from the closed position P1 toward the open position P2. As shown in Figure 8, in the currency handling device 1, when the safety shutter 31 starts rotating from the closed position P1 to the open position P2, the unit shutter 22 of the currency handling unit 3 has reached the vicinity of the insertion slot 7a.

[0066] When the safety shutter 31 rotates from the closed position P1 to the open position P2, the safety shutter 31 retracts from the insertion opening 7a toward the front surface 6F of the device housing 6 while the flat surface 31a of the safety shutter 31 falls toward the front surface 6F of the device housing 6. This makes it easier for the safety shutter 31, particularly the flat surface 31a, retracting from the insertion opening 7a to be visible to a user on the front surface 6F of the device housing 6, so that compared to a structure in which the safety shutter 31 rotates toward the rear surface 6R of the device housing 6, the shutter mechanism 8 can make the user aware of the presence of the safety shutter 31 at the insertion opening 7a.

[0067] Next, as the currency handling unit 3 advances further toward the front surface 6F of the device housing 6, the safety shutter 31 retreats from the insertion slot 7a while the unit shutter 22 advances to close the insertion slot 7a, as shown in Fig. 9. At this time, the unit shutter 22 closing the insertion slot 7a and the safety shutter 31 opening the insertion slot 7a operate in a gradual interchange, making it easier for the user to recognize the presence of the unit shutter 22 and the safety shutter 31.

[0068] This allows the user to easily see the presence of the unit shutter 22 and the safety shutter 31 at the insertion port 7a, so that the user can recognize that the deposit unit 7 is in preparation even when the safety shutter 31 is retracted from the insertion port 7a. Therefore, the currency handling device 1 prevents the user from accidentally inserting currency, fingertips, etc. into the insertion port 7a when attaching or detaching the currency handling unit 3.

[0069] Furthermore, in the currency handling device 1 of the embodiment, when the currency handling unit 3 is attached to or detached from the unit mounting portion 5, the unit shutter 22 moves to a position facing the insertion slot 7a to close the insertion slot 7a, while the shutter operating member 26 operates the shutter mechanism 8 so that the safety shutter 31 moves away from the insertion slot 7a, thereby preventing the entire insertion slot 7a from being open for a period of time. Therefore, the currency handling device 1 can further prevent the user from accidentally inserting currency, fingertips, etc. into the insertion slot 7a when the currency handling unit 3 is attached or detached.

[0070] Next, as the currency handling unit 3 advances further toward the front surface 6F of the device housing 6, the safety shutter 31 rotates further toward the open position P2, and when the safety shutter 31 retracts to a position where it is not visible to a user looking at the insertion slot 7a, as shown in Figure 10, the insertion slot 7a is almost closed by the unit shutter 22 of the currency handling unit 3. Finally, when the safety shutter 31 is rotated to the open position P2, the shutter mechanism 8 closes the insertion slot 7a by the unit shutter 22 of the currency handling unit 3. Furthermore, when the currency handling unit 3 is removed from the unit mounting section 5, the operation of the shutter mechanism 8 is reverse to that described above.

[0071] (Irregular operation of the shutter mechanism) Next, the operation of the locking member 45 and the rotating member 48 during irregular operation of the shutter mechanism 8 will be described with reference to the drawings. Figures 11 to 15, 17, 19, and 20 are side views for explaining irregular operation of the shutter mechanism 8 in the embodiment. Figure 16 is an enlarged side view of the rotating member 48 and the locking member 45 in Figure 15. Figure 18 is an enlarged side view of the rotating member 48 and the locking member 45 in Figure 17.

[0072] In normal operation, which is a series of operations of the shutter mechanism 8 from Figures 7 to 10, the safety shutter 31 rotates from the open position P2 to the closed position P1, and then the locking member 45 moves to the locked position P3, and the locking claw 45b of the locking member 45 engages with the engaging piece 48b of the rotating member 48, thereby locking the safety shutter 31 at the closed position P1 by the locking member 45.

[0073] 11 and 12, during maintenance work on the currency handling device 1, there is a risk that the safety shutter 31, which is located in the open position P2 inside the insertion slot 7a, may be held down by a hand placed inside the insertion slot 7a, and the currency handling unit 3 may be pulled out from the unit mounting section 5. If this irregular operation is performed, the order of rotation of the safety shutter 31 and movement of the locking member 45 will be reversed from the normal operation, and the shutter mechanism 8 will perform an irregular operation.

[0074] When the safety shutter 31, which is in the open position P2, is held down by hand and the currency handling unit 3 is pulled out from the unit mounting section 5, the unlocking portion 27 of the shutter operating member 26, along with the currency handling unit 3, retracts from the unlocking roller 47 of the locking member 45. Accordingly, as shown in FIG. 13 , the locking member 45 moves from the unlocked position P4 to the locked position P3 due to the biasing force of the tension coil spring 46. That is, the locking member 45 moves to the locked position P3 before the safety shutter 31 rotates from the open position P2 to the closed position P1. In other words, the safety shutter 31 rotates from the open position P2 to the closed position P1 after the locking member 45 moves to the locked position P3.

[0075] Subsequently, when the hand holding the safety shutter 31 is released from the safety shutter 31, the safety shutter 31 starts to rotate from the open position P2 toward the closed position P1, as shown in Fig. 14. Then, when the safety shutter 31 passes above the locking member 45 located at the locked position P3, the upper end of the locking claw 45b of the locking member 45 comes into contact with the operating surface 48e of the engaging piece 48b of the rotating member 48 of the shutter mechanism 8, as shown in Figs. 15 and 16. At this time, as shown in Figs. 17 and 18, in the shutter mechanism 8, together with the rotation of the safety shutter 31 toward the closed position P1, the rotating member 48, with which the upper end of the locking claw 45b of the locking member 45 comes into contact, is rotated counterclockwise in the drawings.

[0076] As a result of the rotating member 48 rotating relative to the locking claw 45b of the locking member 45 in this way, the rotation of the safety shutter 31 toward the closed position P1 is not hindered by the locking claw 45b of the locking member 45 positioned at the locking position P3, and the safety shutter 31 can continue to rotate smoothly. Next, the engaging piece 48b of the rotating member 48 moves along the upper end of the locking claw 45b of the locking member 45, and as shown in Fig. 19, the engaging piece 48b of the rotating member 48 passes over the tip of the locking claw 45b of the locking member 45, and the safety shutter 31 passes above the locking claw 45b of the locking member 45 and rotates to the closed position P1.

[0077] When the engaging piece 48b of the rotating member 48 passes the tip of the locking claw 45b of the locking member 45 and the safety shutter 31 rotates to the closed position P1, as shown in Fig. 20, the rotating member 48 rotates back to the initial position due to its own weight, and the locking claw 45b of the locking member 45, which is positioned at the locked position P3, engages with the engaging piece 48b, thereby locking the safety shutter 31 at the closed position P1 by the locking member 45. By performing the irregular operation of the shutter mechanism 8 as described above, even if the safety shutter 31 rotates from the open position P2 to the closed position P1 after the locking member 45 moves to the locked position P3, the safety shutter 31 can be smoothly rotated to the closed position P1.

[0078] (Effects of the Example) As described above, in the currency handling device 1 of the embodiment, when the safety shutter 31 rotates from the blocked position P1 to the open position P2, it retreats from the insertion port 7a toward the front surface 6F of the device housing 6, and the shutter mechanism 8 has a support stay 32 that supports the safety shutter 31 and rotates together with the safety shutter 31, a locking member 45 that is movable between a locking position P3 that locks the safety shutter 31 in the blocked position P1 and an unlocking position P4 that unlocks the locked state of the safety shutter 31, and a rotating member 48 that is rotatably mounted on the support stay 32 and with which the locking member 45 engages at the locking position P3, and the locking member 45 is arranged to engage with the rotating member 48 from the front surface 6F of the device housing 6. When the safety shutter 31 rotates from the open position P2 to the closed position P1 after the locking member 45 has moved to the locking position P3, the locking member 45 positioned at the locking position P3 comes into contact with the rotating member 48, and the rotating member 48 is rotated by the locking member 45, causing the safety shutter 31 to rotate to the closed position P1. Even when the safety shutter 31 rotates from the open position P2 to the closed position P1 after the locking member 45 has moved to the locking position P3 in this way, the rotation of the safety shutter 31 is not hindered by the locking member 45 positioned at the locking position P3, and the safety shutter 31 can be rotated to the closed position P1.

[0079] Furthermore, in the currency handling device 1 of the embodiment, the currency handling unit 3 has a shutter operating member 26 that activates the shutter mechanism 8, and the shutter operating member 26 has an unlocking section 27 that moves the locking member 45 to the unlocked position P4. As a result, by attaching or detaching the currency handling unit 3 to or from the unit mounting section 5, the locking member 45 can be moved to the unlocked position P4, and the safety shutter 31 can be rotated to the open position P2.

[0080] Furthermore, the currency handling unit 3 of the currency handling device 1 of the embodiment has a receiving opening 21 corresponding to the insertion slot 7a and a unit shutter 22 that opens and closes the receiving opening 21, and when the currency handling unit 3 is attached to the unit attachment section 5, the unit shutter 22 moves to a position facing the insertion slot 7a to close the insertion slot 7a, while the shutter operating member 26 operates the shutter mechanism 8 so that the safety shutter 31 retracts from the insertion slot 7a. As a result, when the currency handling unit 3 is attached to or detached from the unit attachment section 5, the unit shutter 22 that closes the insertion slot 7a and the safety shutter 31 that opens the insertion slot 7a operate to gradually switch places. This makes it easier for users to recognize the existence of the unit shutter 22 and the safety shutter 31, and prevents the entire insertion slot 7a from being open for a long time. Therefore, even when the safety shutter 31 is retracted from the deposit port 7a, it is possible to make the user aware that the deposit section 7 is in preparation, further preventing the user from accidentally depositing coins, fingertips, etc. into the deposit port 7a when attaching or detaching the currency handling unit 3.

[0081] Furthermore, the rotating member 48 of the shutter mechanism 8 in the currency handling device 1 of the embodiment has an engagement piece 48b formed with an engagement surface 48d that engages with the locking member 45, and the engagement piece 48b has an operating surface 48e formed on the opposite side of the engagement surface 48d that the locking member 45 comes into contact with when the rotating member 48 is rotated by the locking member 45. In this way, the front and back surfaces of the engagement piece 48b each function as the engagement surface 48d and the operating surface 48e, respectively, and this simplifies the shape of the rotating member 48. As a result, the shutter mechanism 8 is prevented from becoming larger due to the rotating member 48.

[0082] Furthermore, the shutter mechanism 8 of the currency handling device 1 of the embodiment has a stopper member 49 that restricts the rotation range of the rotating member 48. This appropriately restricts the rotation range of the rotating member 48, thereby improving the reliability of the rotation operation of the rotating member 48.

[0083] Furthermore, the stopper member 49 of the shutter mechanism 8 in the currency handling device 1 of the embodiment restricts the rotation range of the rotating member 48 so that after the rotating member 48 is rotated by the locking member 45, the rotating member 48 returns by its own weight to the initial position where it engages with the locking member 45. This simplifies the rotation structure of the rotating member 48 and enables the rotated rotating member 48 to be stably returned to the initial position.

[0084] Furthermore, the locking member 45 of the shutter mechanism 8 in the currency handling device 1 of the embodiment has an arc-shaped curved surface 45e formed at its upper end portion that comes into contact with the operating surface 48e of the rotating member 48, which slides against the rotating member 48 while rotating the rotating member 48. This makes it easier for the operating surface 48e side of the engagement piece 48b of the rotating member 48 to move along the curved surface 45e of the locking member 45 while the upper end of the locking member 45 rotates the rotating member 48, and also makes it possible to reduce the amount of rotation of the rotating member 48 rotated by the locking member 45. This allows the locking member 45 to move more smoothly toward the front surface 6F of the device housing 6 relative to the rotating member 48. [Explanation of symbols]
