Description

TECHNICAL FIELD

[0001] The present disclosure relates to a medium storage device and a method of controlling the medium storage device.

BACKGROUND

[0002] In general, an automated teller machine is an unmanned terminal that enables the deposit and withdrawal of mediums such as cash or checks without time restriction through the use of a cash card or a passbook.

[0003] Such an automated teller machine may have a medium storage box that may store mediums such as cash or checks, and a proper amount of mediums may be stored in the medium storage box. A medium stored in the medium storage box may be taken out of the medium storage box by a customer's request for withdrawal, and a new medium may be carried into the medium storage box by a customer's request for deposit. As such, a proper amount of the mediums stored in the medium storage box need to be maintained in preparation for the customer's request for deposit or withdrawal, and it is necessary to manage and monitor whether a proper amount of mediums is stored in the medium storage box in real time.

[0004] However, when a management company for replenishing the automated teller machine with mediums is far away from the automated teller machine, it is not easy for the management company to manage the amount of mediums in the automated teller machine in real time.

[0005] For example, in the case that a specific type of banknotes are insufficient in the automated teller machine, the automated teller machine may be replenished with the specific type of banknotes through a customer's deposit while a person of the management company goes to replenish the machine with the specific type of banknotes. Further, in the case that a specific type of banknotes is sufficient in the automated teller machine, the specific type of banknotes may be depleted in the automated teller machine through a customer's withdrawal while a person of the management company goes to replenish the machine with a different type of banknotes.

[0006] Meanwhile, a conventional medium storage device is problematic in that it is impossible to selectively take only a specific type of banknotes which need to be replenished among various types of banknotes out from a transit cassette, and to selectively take a desired amount of banknotes which need to be replenished from the transit cassette. Therefore, there is a need for a medium storage device capable of replenishing the machine by taking a desired type of banknotes and a desired amount of banknotes out from a transit cassette that stores various types of banknotes, and transferring an unnecessary type of banknotes back to the transit cassette.

[0025] The disclosure may be variously modified and may include various embodiments. Specific embodiments will be exemplarily illustrated in the drawings and described in the detailed description of the embodiments. However, it should be understood that they are not intended to limit the disclosure to specific embodiments but rather to cover all modifications, similarities, and alternatives which are included in the spirit and scope of the disclosure.

[0026] The terms used herein, including ordinal numbers such as "first" and "second" may be used to describe, and not to limit, various components. The terms simply distinguish the components from one another.

[0027] When it is said that a component is "connected" or "linked" to another component, it should be understood that the former component may be directly connected or linked to the latter component or a third component may be interposed between the two components.

[0028] Specific terms in the present disclosure are used simply to describe specific embodiments without limiting the present disclosure. An expression used in the singular encompasses the expression of the plural, unless it has a clearly different meaning in the context.

[0029] Hereinafter, a specific configuration of a medium storage device 10 according to a first embodiment of the present disclosure will be described with reference to the accompanying drawings.

[0030] As shown in FIGS. 1 to 7, the medium storage device 10 according to the first embodiment of the present disclosure may accommodate a medium in a recycle cassette 500 in the medium storage device 10 through a first transit cassette 810 and a second transit cassette 820 connected to a front portion and a rear portion of a safe 11, and may recover a medium accommodated the recycle cassette 500 through the first transit cassette 810 connected to the front portion of the safe 11.

[0031] The medium storage device 10 may include a safe 11, a temporary holding unit 100, a reception unit 200, an identification unit 300, a conveyance path, a recycle cassette 500, a reject cassette 600, and a control unit 700.

[0032] The safe 11 may provide a storage space to accommodate mediums therein. In the present embodiment, the safe 11 is not limited to a medium storage space, and the safe 11 may include a frame/housing that defines the entire appearance of the medium storage device 10.

[0033] The reception unit 200 may be provided in an upper front portion of the safe 11. Here, the front portion of the safe 11 may be understood as the side (right side of the drawing) where the reception unit 200 through which the deposit and withdrawal of mediums are made by a customer is located. An entrance 12a for replenishment and recovery to which the first transit cassette 810 can be connected may be provided at a lower side of the front portion of the safe 11. An entrance 12b for replenishment and recovery to which the second transit cassette 820 can be connectable may be provided at a lower side of the rear portion of the safe 11 and the temporary holding unit 100 may be provided at an upper rear portion.

[0034] The temporary holding unit 100 may be used for temporarily accommodating mediums. The temporary holding unit 100 may be connected to an upper conveyance path 410 through a first branch conveyance path 431 that will be described later.

[0035] The identification unit 300 may recognize mediums as either a normal medium or a rejection medium, by identifying whether the medium moving along the conveyance path is normal or abnormal. In this specification, the mediums may be divided into the normal medium and the rejection medium. The normal medium is a replenishment medium that needs to be replenished in the medium storage device 10, or a recovery medium that needs to be recovered from the medium storage device 10 to the transit cassette 800. Further, the rejection medium may be an abnormal medium, and may be a damaged or forged banknote or paper other than banknotes. For example, the rejection medium may be a torn banknote, a forged banknote, or a receipt. In addition, the rejection medium may include a normal medium that is not damaged in the first transit cassette 810 but is damaged while moving along the conveyance path, and a normal medium that is not damaged when it is carried into the recycle cassette 500 but is damaged while moving along the conveyance path after carried out from the recycle cassette 500.

[0036] The reception unit 200 may provide a space in which a medium deposited by a customer is carried, and may provide a space from which a medium that needs to be withdrawn by a customer is taken. The reception unit 200 may be connected to a first branch conveyance path 431 through a sixth branch conveyance path 436 that will be described later. When a customer deposits a medium, the reception unit 200 may transfer the deposited medium, through the sixth branch conveyance path 436, the first branch conveyance path 431 and the upper conveyance path 410, to the identification unit 300. In addition, the reception unit 200 may be connected through a seventh branch conveyance path 437 to a front connection point at which the upper conveyance path 410 and the lower conveyance path 420 are connected.

[0037] The recycle cassette 500 may accommodate a medium. The medium accommodated in the recycle cassette 500 may be taken out through the first transit cassette 810 when a recovery is required, and the medium may be taken out through the reception unit 200 when a customer requests withdrawal. The medium deposited into the reception unit 200 by the customer's deposit request may be carried into the recycle cassette 500 through the identification unit 300.

[0038] A plurality of recycle cassettes 500 may be provided. For example, the recycle cassette 500 may include a first recycle cassette 510, a second recycle cassette 520, a third recycle cassette 530, and a fourth recycle cassette 540 that are subsequently arranged in the direction toward the front portion of the safe 11 (where the reception unit 200 is located). In this case, the first recycle cassette 510 may be disposed on the rear side in the safe 11 with respect to the front-side branch point of the upper conveyance path 410 and the lower conveyance path 420, and the second recycle cassette 520, the third recycle cassette 530, and the fourth recycle cassette 540 are disposed on the front side of the safe 11 with respect to the front-side branch point of the upper conveyance path 410 and the lower conveyance path 420. In this case, when the medium is carried in (replenished) through the first transit cassette 810, the medium identified as the normal medium by the identification unit 300 may be replenished preferentially in the first cycle cassette 510 over the remaining cycle cassettes 520, 530, and 540. Accordingly, when the medium temporarily accommodated in the second transit cassette 820 is conveyed through the identification unit 300 to the recycle cassette 500, the medium identified as the normal medium by the identification unit 300 may be conveyed to the remaining recycle cassettes 520, 530 and 540 except for the first recycle cassette 510 (see FIG. 4).

[0039] When the medium is carried in (replenished) through the first transit cassette 810, if the first recycle cassette 510 is not replenished preferentially over the remaining recycle cassettes 520, 530, and 540, that is, if the first recycle cassette 510 is replenished partially like the remaining recycle cassettes 520, 530 and 540, when the medium temporarily accommodated in the second transit cassette 820 is conveyed through the identification unit 300 to the recycle cassette 500 as shown in FIG. 4, there may occur a collision between the medium conveyed from the second transit cassette 820 to the identification unit 300 and the medium conveyed through the identification unit 300 to the first recycle cassette 510. Accordingly, in the present embodiment, when the medium is carried in (replenished) through the first transit cassette 810, the medium identified as the normal medium by the identification unit 300 is replenished preferentially in the first recycle cassette 510 over the remaining recycle cassettes 520, 530 and 540.

[0040] A sensor (not shown) may be provided in the recycle cassette 500 to maintain a proper amount of mediums according to the type of mediums in preparation for a customer's deposit or withdrawal request. Such a sensor may sense whether a proper amount of mediums is accommodated in the recycle cassette 500, and may inform a management company for the medium storage device 10 whether the mediums in the recycle cassette 500 are insufficient.

[0041] The reject cassette 600 may accommodate a damaged medium (e.g., rejection banknote). The reject cassette 600 may be disposed in a lower front portion of the safe 11 to be positioned adjacent to the first transit cassette 810. Since the reject cassette 600 is disposed adjacent to the first transit cassette 810, mediums may be rapidly moved between the reject cassette 600 and the first transit cassette 810. For example, in the case that a medium which is being conveyed from the recycle cassette 500 to the first transit cassette 810 is damaged during the transfer and is identified as a rejection medium in the identification unit 300, the rejection medium may be accommodated in the reject cassette 600.

[0042] The conveyance path may convey mediums between the temporary holding unit 100, the identification unit 300, the reception unit 200, the recycle cassette 500, the reject cassette 600, the first transit cassette 810 and the second transit cassette 820.

[0043] Such a conveyance path may include a driving roller, a driven roller, a switch gate and the like to transfer the mediums. Further, the conveyance path may be driven by a motor (not shown), and may be controlled by a control unit 700. The conveyance path may include an upper conveyance path 410, a lower conveyance path 420, a first branch conveyance path 431, a second branch conveyance path 432, a third branch conveyance path 433, a fourth branch conveyance path 434, a fifth branch conveyance path 435, an sixth branch conveyance path 436 and a seventh branch conveyance path 437.

[0044] The upper conveyance path 410 may provide a moving path of mediums that are input/output to/from the identification unit 300. The upper conveyance path 410 may be connected to the lower conveyance path 420 to form a closed loop. The upper conveyance path 410 may be provided above the lower conveyance path 420. The first branch conveyance path 431 may branch from the upper conveyance path 410. The upper conveyance path 410 may transmit mediums, conveyed from the temporary holding unit 100 or the reception unit 200, through the identification unit 300 to the lower conveyance path 420, or may transmit mediums output from the identification unit 300 to the temporary holding unit 100, the reception unit 200 or the lower conveyance path 420.

[0045] The lower conveyance path 420 may be connected to the upper conveyance path 410 to form a closed loop. The second branch conveyance path 432 may branch from the lower conveyance path 420. In the lower conveyance path 420, a branch point to the recycle cassette 500 and a branch point to the reject cassette 600 may be sequentially placed in the direction toward the front of the safe 11. The switch gate may be provided at each branch point of the lower conveyance path 420 to be operated under the control of the control unit 700. The lower conveyance path 420 may convey mediums, conveyed from the upper conveyance path 410, to the second transit cassette 820, the recycle cassette 500 or the reject cassette 600 by adjusting the switch gates under the control of the control unit 700, or may convey mediums, conveyed from the second transit cassette 820 and the recycle cassette 500, to the upper conveyance path 410.

[0046] The first branch conveyance path 431 may branch from the upper conveyance path 410 to provide a medium moving path between the upper conveyance path 410 and the temporary holding unit 100. The first branch conveyance path 431 may branch upwardly from the upper conveyance path 410. The sixth branch conveyance path 436 may branch from the first branch conveyance path 431. The switch gate operated under the control of the control unit 700 may be provided at a branch point of the first branch conveyance path 431 from which the sixth branch conveyance path 436 branches.

[0047] The second branch conveyance paths 432 may branch from the lower conveyance path 420 to provide medium moving paths between the lower conveyance path 420 and the recycle cassettes 500. The second branch conveyance paths 432 may branch from the lower conveyance path 420 toward below in the direction toward the front portion of the safe 11.

[0048] The third branch conveyance path 433 may branch from a connection point between the upper conveyance path 410 and the lower conveyance path 420. The third branch conveyance path 433 may branch from the lower conveyance path 420 toward below in the direction toward the rear portion of the safe 11. The third branch conveyance path 433 may provide a medium moving path between the upper conveyance path 410 and the reject cassette 600, or a medium moving path between the lower conveyance path 420 and the reject cassette 600, by adjusting the switch gate under the control of the control unit 700.

[0049] The fourth branch conveyance path 434 may provide a medium moving path between a front-side connection point of the upper conveyance path 410 and the lower conveyance path 420, and the entrance 12a for replenishment and recovery. For example, along the fourth branch conveyance path 434, a medium conveyed from the first transit cassette 810 may be conveyed to the upper conveyance path 410, or a medium conveyed from the upper conveyance path 410 may be conveyed to the first transit cassette 810.

[0050] The fifth branch conveyance path 435 may provide a medium moving path between a rear-side connection point of the upper conveyance path 410 and the lower conveyance path 420 and the entrance 12b for replenishment and recovery. For example, along the fifth branch conveyance path 435, a medium conveyed from the second transit cassette 820 may be conveyed to the upper conveyance path 410, or a medium conveyed from the upper conveyance path 410 may be conveyed to the second transit cassette 820.

[0051] The sixth branch conveyance path 436 may branch from the first branch conveyance path 431 to be connected to the reception unit 200. The sixth branch conveyance path 436 may provide a medium moving path between the reception unit 200 and the temporary holding unit 100, or a medium moving path between the reception unit 200 and the upper conveyance path 410, by adjusting the switch gate under the control of the control unit 700.

[0052] The seventh branch conveyance path 437 may branch from the connection point between the upper conveyance path 410 and the lower conveyance path 420 to be connected to the reception unit 200. A medium conveyed from the reception unit 200 may be conveyed to the lower conveyance path 420 along the seventh branch conveyance path 437, by adjusting the switch gate under the control of the control unit 700.

[0053] The switch gates may be provided at branch points of the upper conveyance path 410, the lower conveyance path 420, the first branch conveyance path 431, the second branch conveyance path 432, the third branch conveyance path 433, the fourth branch conveyance path 434, the fifth branch conveyance path 435, the sixth branch conveyance path 436 and the seventh branch conveyance path 437 to switch a medium moving path. The switch gate may change its posture through rotation to selectively determine the medium moving path under the control of the control unit 700.

[0054] The control unit 700 may control the conveyance path such that, among mediums carried through the first transit cassette 810, the normal medium is conveyed to the recycle cassette 500 and the rejection medium is temporarily accommodated in the second transit cassette 820 to be conveyed back to the first transit cassette 810. Further, the control unit 700 may control the conveyance path such that, among mediums accommodated in the recycle cassette 500, the normal medium is conveyed to the first transit cassette 810 and the rejection medium is conveyed to the reject cassette 600. The control unit 700 may be implemented by a calculation device including a microprocessor, a measuring device such as a sensor, and a memory. Since the implementation method is obvious to those skilled in the art, a detailed description thereof will be omitted. Hereinafter, the control method of the control unit 700 will be described in detail.

[0055] Specifically, referring to FIGS. 2 to 3, the control unit 700 may sequentially control the fourth branch conveyance path 434 and the upper conveyance path 410 to transfer the medium conveyed from the first transit cassette 810 to the identification unit 300. Further, the control unit 700 may control the conveyance path to transfer mediums to different places according to the types of the mediums identified in the identification unit 300.

[0056] For example, as shown in FIG. 2, the control unit 700 may control the upper conveyance path 410, the lower conveyance path 420 and the second branch conveyance path 432 such that the normal medium identified in the identification unit 300 is conveyed to the recycle cassette 500.
