Description

Financial automation devices and financial automation device control methods

[0001] The present invention relates to a financial automation device and a method for controlling the financial automation device.

[0002] Typically, an automated teller machine (ATM) is a device installed outside of a bank's teller window, allowing users to conveniently access various financial services regardless of time or location. ATMs can provide various financial services, such as cash deposits and withdrawals, account transfers, balance inquiries, and passbook accounting.

[0003] These financial automation devices include a media thickness detection unit that detects the thickness of media returned from the financial automation device. The media thickness detection unit includes a thickness detection reference roller fixed to the body of the financial automation device and a thickness detection auxiliary roller that is arranged to be movable at least in the vertical direction above the thickness detection reference roller. The media thickness detection unit detects the thickness of the media by detecting the vertical displacement of the thickness detection auxiliary roller when the media passes between the thickness detection reference roller and the thickness detection auxiliary roller.

[0004] Meanwhile, among the media deposited into automated teller machines by users, there are media that are at least partially torn, and at least some of the torn media are stuck together with tape or other means. In other words, there are media that are stuck together with tape or other means. In some countries, media stuck together with tape or other means are stored in automated teller machines to be exchanged for untorn media, preventing them from being traded in the market. In other countries, they are not stored in automated teller machines and are returned to the user.

[0005] When the concentricity of the thickness detection reference roller of the medium thickness detection unit is relatively good, the influence of the concentricity of the thickness detection reference roller is small, so the thickness of the medium can be detected relatively accurately. Therefore, when the concentricity of the thickness detection reference roller of the medium thickness detection unit is relatively good, tape, etc. attached to the medium can be detected relatively precisely, so the medium attached with tape, etc. can be easily detected.

[0006] However, if the concentricity of the thickness detection reference roller of the media thickness detection unit is not good, the concentricity of the thickness detection reference roller affects the thickness detection of the media, so the thickness of the media cannot be detected relatively accurately. Therefore, if the concentricity of the thickness detection reference roller of the media thickness detection unit is not good, tape, etc. attached to the media cannot be detected relatively precisely, so the media attached with tape, etc. cannot be easily detected. In other words, if the concentricity of the thickness detection reference roller is not good, the degree of eccentricity of the thickness detection reference roller may have a size similar to or larger than the thickness of tape, etc., which is relatively smaller than the thickness of the media. Therefore, if the concentricity of the thickness detection reference roller of the media thickness detection unit is not good, there may be an error in detecting the media attached with tape, etc. as normal media.

[0007] In the past, the concentricity of the thickness sensing reference roller of the medium thickness sensing unit was maintained relatively well so that it did not affect the thickness sensing of the medium. For example, the concentricity of the thickness sensing reference roller was maintained at 1 / 100, and for this purpose, the thickness sensing reference roller was precisely machined with an accuracy of 1 / 1000 to 5 / 1000. Therefore, the conventional thickness sensing reference roller had the disadvantage of being relatively expensive.

[0008] Embodiments of the present invention have been invented against the background described above, and are intended to provide a financial automation device and a financial automation device control method capable of detecting the thickness of a medium relatively precisely even when the concentricity of the thickness detection reference roller is not good, by correcting the detected thickness of the medium when detecting the thickness of the medium such as banknotes in consideration of the concentricity of the thickness detection reference roller used to detect the thickness of the medium.

[0009] A financial automation device according to one aspect of the present invention comprises: a body; a thickness sensing roller unit including a thickness sensing reference roller fixed to the body and a thickness sensing auxiliary roller arranged to be movable in an up-and-down direction above the thickness sensing reference roller; a medium thickness sensing unit including a roller displacement sensing unit that detects an up-and-down displacement of the thickness sensing auxiliary roller with respect to the thickness sensing reference roller; And a controller for calculating the thickness of the medium based on the vertical displacement detected by the roller displacement detection unit, wherein the medium is in a medium non-passing state in which the medium does not pass between the thickness detection reference roller and the thickness detection auxiliary roller, or in a medium passing state in which the medium passes between the thickness detection reference roller and the thickness detection auxiliary roller, and in the medium non-passing state, the thickness detection auxiliary roller and the thickness detection reference roller are configured to contact each other, and the controller calculates the thickness of the medium by subtracting the medium non-passing phase, which is the vertical displacement of the medium non-passing state, from the medium passing phase, which is the vertical displacement of the medium passing state.

[0010] In addition, the medium thickness detection unit may further include a medium detection sensor that detects passage of the medium by a thickness detection distance in the opposite direction of the medium's return direction from the thickness detection roller unit.

[0011] In addition, the thickness sensing reference roller further includes an encoder arranged on the thickness sensing reference roller to detect a rotational position of the thickness sensing reference roller, the encoder detects a plurality of rotational positions of the thickness sensing reference roller while the thickness sensing reference roller rotates once, and the roller displacement detection unit can detect the medium non-passing phase at the plurality of rotational positions.

[0012] In addition, the thickness detection separation distance is greater than the circumference of the thickness detection reference roller, and the roller displacement detection unit can detect the medium non-passing phase while the medium is detected by the medium detection sensor and the medium is returned to the thickness detection roller unit.

[0013] Additionally, the controller can determine one or more reference rotation positions among the plurality of rotation positions based on the point in time at which the medium is detected by the medium detection sensor.

[0014] Additionally, the controller can calculate the thickness of the medium by subtracting the medium non-passing phase at the one or more reference rotation positions from the medium passing phase at the one or more reference rotation positions.

[0015] In addition, the roller displacement detection unit may include a lever member connected to the thickness detection auxiliary roller so as to move together with the thickness detection auxiliary roller; a magnet disposed on one of the lever member and the body; and a Hall sensor disposed on the other of the lever member and the body so as to correspond to the magnet and detecting the magnetic force of the magnet.

[0016] In addition, before each financial transaction, the thickness sensing reference roller is rotated, the encoder detects multiple rotational positions of the thickness sensing reference roller, and the roller displacement detection unit detects the media non-passing phase at the multiple rotational positions, so that the concentricity of the thickness sensing reference roller can be measured.

[0017] A method for controlling a financial automation device according to another aspect of the present invention comprises: a medium non-passing phase detection step of detecting a medium non-passing phase, which is a vertical displacement of a thickness-sensing auxiliary roller with respect to a thickness-sensing reference roller, in a medium non-passing state in which the medium does not pass between the thickness-sensing reference roller and the thickness-sensing auxiliary roller; a medium passing phase detection step of detecting a medium passing phase, which is a vertical displacement of the thickness-sensing auxiliary roller with respect to the thickness-sensing reference roller, in a medium passing state in which the medium passes between the thickness-sensing reference roller and the thickness-sensing auxiliary roller; And it includes a medium thickness calculation step of calculating the thickness of the medium by subtracting the medium passage phase from the medium non-passing phase, wherein the thickness sensing reference roller is fixed to the body, and the thickness sensing auxiliary roller is arranged at least vertically movable on the upper side of the thickness sensing reference roller, and the thickness sensing auxiliary roller and the thickness sensing reference roller are in contact with each other in the medium non-passing state. In addition, it further includes a medium sensing step of detecting passage of the medium by a medium sensing sensor, and the medium sensing sensor can be spaced apart from the thickness sensing roller unit including the thickness sensing reference roller and the thickness sensing auxiliary roller by a thickness sensing distance in a direction opposite to the conveying direction of the medium.

[0018] In addition, in the above-described medium non-passing phase detection step, an encoder disposed on the thickness-sensing reference roller detects a plurality of rotational positions of the thickness-sensing reference roller while the thickness-sensing reference roller rotates once, and can detect the medium non-passing phase at the plurality of rotational positions.

[0019] In addition, the thickness sensing separation distance is greater than the circumference of the thickness sensing reference roller, and the medium non-passing phase sensing step can be performed while the passage of the medium is sensed in the medium sensing step and the medium is returned to the thickness sensing roller unit.

[0020] In addition, in the medium non-passing phase detection step or the medium passing phase detection step, one or more reference rotation positions are determined from among the plurality of rotation positions based on the time point at which the medium is detected, and in the medium thickness calculation step, the thickness of the medium can be calculated by subtracting the medium non-passing phase at the one or more reference rotation positions from the medium passing phase at the one or more reference rotation positions.

[0021] According to embodiments of the present invention, when detecting the thickness of a medium such as a banknote, there is an effect in which the detected thickness of the medium can be corrected by taking into account the concentricity of the thickness detection reference roller used to detect the thickness of the medium.

[0022] In addition, according to embodiments of the present invention, even if the concentricity of the thickness sensing reference roller is not good, there is an effect of being able to detect the thickness of the medium relatively precisely.

[0023] In addition, according to embodiments of the present invention, even if the concentricity of the thickness sensing reference roller is not good, there is an effect of being able to detect a medium attached by tape or the like.

[0041] Hereinafter, with reference to FIGS. 1 and 2, a specific configuration of a financial automation device (1) according to an embodiment of the present invention will be described. The financial automation device (1) can inspect and classify media (2) such as banknotes deposited by a user and store them according to the inspection results, or withdraw the stored media (2) to the user. The financial automation device (1) may include a body (100), a reception unit (200), a media thickness detection unit (300), a deposit media inspection unit (400), a temporary holding unit (500), a rejection unit (600), a storage unit (700), a withdrawal media inspection unit (800), a return path (900), and a controller (1000).

[0042] Referring to FIG. 1, inside the body (100), a reception unit (200), a media thickness detection unit (300), a deposit medium discrimination unit (400), a temporary holding unit (500), a rejection unit (600), a storage unit (700), a withdrawal medium discrimination unit (800), a return path (900), and a controller (1000) may be arranged and supported. Inside the body (100), a space may be formed in which the reception unit (200), a media thickness detection unit (300), a deposit medium discrimination unit (400), a temporary holding unit (500), a rejection unit (600), a storage unit (700), a withdrawal medium discrimination unit (800), a return path (900), and a controller (1000) may be arranged. A media entry / exit port (not shown) may be formed in the body (100). The media input / output port may be connected to the reception area (200). A user may insert media (2) into the reception area (200) through the media input / output port. In addition, a user may receive media (2) returned to the reception area (200) through the media input / output port.

[0043] Referring to FIG. 1, a medium (2) such as banknotes is inserted by a user through a medium input / output into the reception unit (200), accumulated, and then returned to the deposit medium identification unit (400), or the medium (2) returned from the deposit medium identification unit (400) is accumulated and then taken out through the medium input / output so that the user can receive it. The medium (2) inserted into the reception unit (200) through the medium input / output and accumulated can be separated into individual sheets and returned to the deposit medium identification unit (400) as individual sheets. In addition, the medium (2) can be returned as individual sheets from the deposit medium identification unit (400), accumulated in the reception unit (200), and taken out through the medium input / output.

[0044] Referring to FIG. 2, the medium thickness detection unit (300) can detect the thickness of the medium (2). The medium thickness detection unit (300) is disposed on the return path (900) and can detect the thickness of the medium (2) being returned on the return path (900). For example, the medium thickness detection unit (300) is disposed between the reception unit (200) and the deposit medium discrimination unit (400) of the upper return path (910) included in the return path (900), which will be described later, and can detect the thickness of the medium (2) being returned from the reception unit (200) to the deposit medium discrimination unit (400). The medium thickness detection unit (300) may include a medium detection sensor (310), a thickness detection roller unit (320), a roller displacement detection unit (330), and an encoder (340).

[0045] The medium detection sensor (310) can detect the passage of the medium (2). The medium detection sensor (310) can be disposed spaced apart from the thickness detection roller unit (320) by a thickness detection distance (LT) in the opposite direction of the conveyance direction of the medium (2). In other words, the thickness detection roller unit (320) can be disposed spaced apart from the medium detection sensor (310) by a thickness detection distance (LT) in the conveyance direction of the medium (2). The thickness detection distance (LT) can be greater than the circumference of a thickness detection reference roller (321) included in the thickness detection roller unit (320), which will be described later. In addition, the medium (2) can reach the thickness detection roller unit (320) only when the medium detection sensor (310) detects the passage of the medium (2) and the medium (2) is conveyed a distance longer than the circumference of the thickness detection reference roller (321). The medium detection sensor (310) is connected to the controller (1000) and can transmit the passage of the medium (2) to the controller (1000). The medium detection sensor (310) may include a medium detection light emitting unit (311) and a medium detection light receiving unit (312).

[0046] The medium detection light emitting unit (311) may be configured to irradiate light to the medium detection light receiving unit (312). The medium detection light emitting unit (311) may be arranged to face the medium detection light receiving unit (312) with a medium return path (RT) in between, through which the medium (2) is returned via the return path (900). For example, the medium detection light emitting unit (311) may be arranged above the medium return path (RT) at a predetermined distance from the medium return path (RT) to irradiate light to the medium detection light receiving unit (312).

[0047] The medium detection light receiving unit (312) may be configured to detect light irradiated from the medium detection light emitting unit (311). The medium detection light receiving unit (312) may be arranged to face the medium detection light emitting unit (311) with the medium return path (RT) interposed therebetween. For example, the medium detection light receiving unit (312) may be arranged at a predetermined distance from the medium return path (RT) on the lower side of the medium return path (RT) so as to face the medium detection light emitting unit (311) arranged on the upper side of the medium return path (RT). When the medium (2) is returned on the medium return path (RT) and passes between the medium detection light emitting unit (311) and the medium detection light receiving unit (312), the medium (2) may block the light irradiated from the medium detection light emitting unit (311). If the medium (2) blocks the light emitted from the medium detection light emitting unit (311), the medium detection light receiving unit (312) may not be able to detect the light emitted from the medium detection light emitting unit (311). In addition, since the medium detection light receiving unit (312) cannot detect the light emitted from the medium detection light emitting unit (311) by the medium (2), the passage of the medium (2) can be detected.

[0048] The thickness sensing roller unit (320) may be configured to sense the thickness of the medium (2). The thickness sensing roller unit (320) may be placed in a medium non-passing state in which the medium (2) does not pass between the thickness sensing reference roller (321) and the thickness sensing auxiliary roller (322) to be described later, or in a medium passing state in which the medium (2) passes between the thickness sensing reference roller (321) and the thickness sensing auxiliary roller (322). In addition, the thickness sensing roller unit (320) may be configured such that the thickness sensing auxiliary roller (322) and the thickness sensing reference roller (321) come into contact with each other in the medium non-passing state. The thickness sensing roller unit (320) may be placed in the return path (900). For example, the thickness detection roller unit (320) may be arranged between the reception unit (200) of the upper return path (910) of the return path (900) and the deposit medium discrimination unit (400). The thickness detection roller unit (320) may be arranged spaced apart from the medium detection sensor (310) in the return direction of the medium (2) by a thickness detection distance (LT). The thickness detection roller unit (320) may include a thickness detection reference roller (321), a thickness detection auxiliary roller (322), and an elastic member (not shown).

[0049] The thickness sensing reference roller (321) can be fixed to the body (100). In other words, the rotational axis of the thickness sensing reference roller (321) can be arranged on the body (100) so as to only rotate and not move. The thickness sensing reference roller (321) can return the medium (2) in the return direction. The rotational axis of the thickness sensing reference roller (321) is connected to a roller driving unit (not shown) including a motor (not shown) that provides rotational force, and can rotate in the return direction of the medium (2), thereby returning the medium (2) in the return direction. The roller driving unit is connected to a controller (1000) and can be driven or stopped according to a command of the controller (1000).

[0050] The thickness sensing auxiliary roller (322) can be arranged so as to be movable at least in the vertical direction on the upper side of the thickness sensing reference roller (321). In other words, the rotational axis of the thickness sensing auxiliary roller (322) can be arranged on the body (100) so as to be rotatable as well as movable at least in the vertical direction. The thickness sensing auxiliary roller (322) can be brought into contact with the thickness sensing reference roller (321) in a medium-non-passing state. For example, in a medium-non-passing state, at least a part of the lower portion of the thickness sensing auxiliary roller (322) can be brought into contact with at least a part of the upper portion of the thickness sensing reference roller (321). In a medium-non-passing state, the thickness sensing auxiliary roller (322) can be brought into contact with the thickness sensing reference roller (321) by the elastic force of the elastic member. The thickness sensing auxiliary roller (322) can be moved at least in the vertical direction according to the concentricity of the thickness sensing reference roller (321) in the medium non-passing state. In other words, the thickness sensing auxiliary roller (322) can be moved at least in the vertical direction according to the degree of eccentricity of the thickness sensing reference roller (321) in the medium non-passing state. In addition, the thickness sensing auxiliary roller (322) can be moved at least in the vertical direction by the medium (2) passing between the thickness sensing reference roller (321) and the thickness sensing auxiliary roller (322) in the medium passing state.

[0051] The elastic member can provide elasticity to the thickness sensing auxiliary roller (322) so that the thickness sensing auxiliary roller (322) can contact the thickness sensing reference roller (321) in a medium non-passing state. The elastic member can be arranged in the body (100) so as to provide elasticity to the thickness sensing auxiliary roller (322) in the direction of the thickness sensing reference roller (321).

[0052] The roller displacement detection unit (330) can detect the vertical displacement of the thickness-sensing auxiliary roller (322) with respect to the thickness-sensing reference roller (321). The roller displacement detection unit (330) is connected to the controller (1000) and can transmit the detected vertical displacement of the thickness-sensing auxiliary roller (322) to the controller (1000). The roller displacement detection unit (330) can detect the media non-passing phase, which is the vertical displacement of the thickness-sensing auxiliary roller (322) with respect to the thickness-sensing reference roller (321), in the media non-passing state of the thickness-sensing roller unit (320). This media non-passing phase can indicate the concentricity of the thickness-sensing reference roller (321). In other words, the media non-passing phase can indicate the degree of eccentricity of the thickness-sensing reference roller (321), etc. In addition, the roller displacement detection unit (330) can detect the media passage phase, which is the vertical displacement of the thickness detection auxiliary roller (322) with respect to the thickness detection reference roller (321) in the media passage state of the thickness detection roller unit (320). The media passage phase can represent the sum of the concentricity of the thickness detection reference roller (321) and the thickness of the medium (2). In other words, the media passage phase can represent, for example, the sum of the eccentricity of the thickness detection reference roller (321) and the thickness of the medium (2).

[0053] The roller displacement detection unit (330) can detect a media non-passing phase while the media (2) is detected by the media detection sensor (310) and the media (2) is returned to the thickness detection roller unit (320). In other words, the roller displacement detection unit (330) can detect the media non-passing phase during at least a portion of the media non-passing state of the thickness detection roller unit (320). In addition, the roller displacement detection unit (330) can detect a media non-passing phase at a plurality of rotational positions of the thickness detection reference roller (321), which will be described later, detected by the encoder (340). In addition, the roller displacement detection unit (330) can detect a media passing phase at a plurality of rotational positions of the thickness detection reference roller (321). The roller displacement detection unit (330) can include a lever member (331), a magnet (332), and a Hall sensor (333).

[0054] The lever member (331) can be connected to the thickness sensing auxiliary roller (322) so as to move together with the thickness sensing auxiliary roller (322). For example, one side of the lever member (331) can be connected to the thickness sensing auxiliary roller (322) and the other side can be rotatably connected to the body (100).

[0055] The magnet (332) can be placed on either the lever member (331) or the body (100). For example, the magnet (332) can be placed on the upper portion of the lever member (331).

[0056] The Hall sensor (333) can detect the magnetic force of the magnet (332) by being arranged on the other of the lever member (331) and the body (100) so as to correspond to the magnet (332). For example, the Hall sensor (333) can be arranged on the body (100) above the magnet (332) so as to be spaced apart from the magnet (332) in the vertical direction by a predetermined distance. The Hall sensor (333) can detect a change in the magnetic force transmitted from the magnet (332) as the lever member (331) moves together with the thickness sensing auxiliary roller (322) and the position of the magnet (332) changes. The vertical displacement of the thickness sensing auxiliary roller (322) can be detected by the change in the magnetic force transmitted from the magnet (332) detected by the Hall sensor (333). In other words, when the lever member (331) moves together with the thickness-sensing auxiliary roller (322) and the position of the magnet (332) changes, and the magnetic force transmitted from the magnet (332) changes, the voltage generated from the hall sensor (333) can change. In addition, the vertical displacement of the thickness-sensing auxiliary roller (322) can be detected by the change in the voltage generated from the hall sensor (333). The hall sensor (333) is connected to the controller (1000) and can transmit the detected vertical displacement of the thickness-sensing auxiliary roller (322) to the controller (1000).

[0057] Referring to FIG. 3, an encoder (340) may be placed on the thickness sensing reference roller (321) to detect the rotational position of the thickness sensing reference roller (321). The encoder (340) may detect a plurality of rotational positions of the thickness sensing reference roller (321) while the thickness sensing reference roller (321) rotates once. For example, the encoder (340) may detect 45 rotational positions of the thickness sensing reference roller (321) while the thickness sensing reference roller (321) rotates once. The encoder (340) may be connected to the controller (1000) and may transmit a plurality of rotational positions of the thickness sensing reference roller (321) detected while the thickness sensing reference roller (321) rotates once to the controller (1000). The encoder (340) may include a turntable (341) and an encoder counter (342).

[0058] The rotary plate (341) is connected to the rotation axis of the thickness sensing reference roller (321) and can rotate together with the thickness sensing reference roller (321). A plurality of slits (341-1) and a plurality of blocking portions (341-2) can be formed on the rotary plate (341). The plurality of slits (341-1) can be formed at regular intervals in the circumferential direction of the rotary plate (341) on the edge of the rotary plate (341). For example, 45 slits (341-1) can be formed at regular intervals in the circumferential direction of the rotary plate (341) on the edge of the rotary plate (341). In addition, a plurality of blocking portions (341-2) can be formed between the plurality of slits (341-1).

[0059] The encoder counter (342) includes a counter light-emitting unit (not shown) and a counter light-receiving unit (not shown), and the counter light-emitting unit and the counter light-receiving unit can be positioned facing each other on both sides of a turntable (341) having a slit (341-1) formed therein. For example, the counter light-emitting unit can be positioned a predetermined distance apart from one side of the turntable (341), and the counter light-receiving unit can be positioned a predetermined distance apart from the other side of the turntable (341) so as to face the counter light-receiving unit. In addition, the encoder counter (342) can be configured to output a light or dark signal depending on whether light emitted from the counter light-emitting unit reaches the counter light-receiving unit. One cycle in which a light signal is output from the encoder counter (342), a dark signal is output, and then a light signal is output again can be referred to as an encoder pulse. Additionally, one encoder pulse can represent one of multiple rotational positions of the thickness sensing reference roller (321). For example, if 45 slits (341-1) are formed at regular intervals in the circumferential direction of the rotation plate (341) on the edge of the rotation plate (341), 45 encoder pulses can be generated, and the 45 encoder pulses can represent 45 rotational positions of the thickness sensing reference roller (321).

[0060] Referring back to FIG. 1, the deposit medium identification unit (400) can identify the medium (2) that is returned in individual sheets from the reception unit (200). When the medium thickness detection unit (300) is arranged between the reception unit (200) and the deposit medium identification unit (400), the deposit medium identification unit (400) can identify the medium (2) whose thickness is detected by the medium thickness detection unit (300) while being returned in individual sheets from the reception unit (200). The deposit medium identification unit (400) can identify whether the medium (2) is abnormal and its denomination, and can count the medium (2). The deposit medium identification unit (400) can identify whether the medium is a normal or an abnormal note, and can identify whether the normal note is a non-returnable note or a returnable note.

[0061] Here, an abnormal note refers to a medium that cannot be deposited. For example, abnormal notes may include old, folded, counterfeit, or suspicious notes, etc., whose image cannot be read. Among abnormal notes, those stored in an automated financial device (1) and not returned to the user may be referred to as rejected notes. Normal notes are not judged as abnormal and may include non-refundable notes and refundable notes. Non-refundable notes refer to media with relatively low user and circulation frequencies, and are used only for deposits and not for withdrawals. Refundable notes refer to media with relatively high user and circulation frequencies, and are used for both deposits and withdrawals. In other words, refundable notes refer to media that can be deposited from users and withdrawn from users. Non-refundable and refundable notes can be distinguished based on the denomination of the medium. Refundable notes may be set as relatively low denominations compared to non-refundable notes, and non-refundable notes may be set as relatively high denominations compared to refundable notes. Meanwhile, the non-refundable right can be specified by the user.

[0062] The temporary holding unit (500) can temporarily hold normal notes among the media (2) identified by the deposit medium identification unit (400). In other words, the temporary holding unit (500) can temporarily hold non-refundable notes and refundable notes identified as normal notes by the deposit medium identification unit (400). Normal notes temporarily held in the temporary holding unit (500) can be returned to the storage unit (700) and stored therein or returned to the reception desk (200) and returned to the customer. If the customer selects to receive a deposit, normal notes temporarily held in the temporary holding unit (500) can be stored in the storage unit (700). If the customer selects to cancel a deposit, normal notes temporarily held in the temporary holding unit (500) can be returned to the reception desk (200) and returned to the customer.

[0063] The rejection unit (600) can temporarily hold abnormal notes among the media (2) identified by the deposit medium identification unit (400). In other words, the rejection unit (600) can temporarily store abnormal deposit notes identified as abnormal notes by the deposit medium identification unit (400).

[0064] The storage unit (700) may store normal notes temporarily held in the temporary holding unit (500). In addition, the storage unit (700) may store media (2) identified as abnormal notes for withdrawal, which will be described later, when withdrawing the stored media (2). The storage unit (700) may include a deposit-only storage unit (710) and a refund storage unit (720). In the deposit-only storage unit (710), non-refundable notes among normal notes identified by the deposit medium identification unit (400) and temporarily held in the temporary holding unit (500) may be returned and stored. In addition, the deposit-only storage unit (710) may store abnormal notes for withdrawal identified by the withdrawal medium identification unit (800) and temporarily held in the temporary holding unit (500). In addition, the reflux storage unit (720) can store reflux notes among the normal notes that have been identified by the deposit medium identification unit (400) and temporarily held in the temporary holding unit (500). The reflux storage unit (720) can be provided in multiple units so that the reflux notes can be stored separately by type.

[0065] The withdrawal medium identification unit (800) can identify the medium (2) that is returned individually from the reflux storage unit (720) for withdrawal. The withdrawal medium identification unit (800) can identify whether the medium (2) is abnormal and the denomination, and can count the medium (2). In addition, the withdrawal medium identification unit (800) can identify whether the medium is normal or abnormal. Among the media (2) identified by the withdrawal medium identification unit (800), normal notes can be returned to the reception unit (200) for withdrawal. Among the media (2) identified by the withdrawal medium identification unit (800), abnormal notes for withdrawal can be temporarily stored in the temporary holding unit (500), and then returned to the deposit-only storage unit (710) for storage when the withdrawal of normal notes is completed.

[0066] The return path (900) can return media between the reception section (200), the media thickness detection section (300), the deposit media identification section (400), the temporary holding section (500), the rejection section (600), the storage section (700), and the withdrawal media identification section (800). The return path (900) can include an upper return path (910), a lower return path (920), and a gate (930).

[0067] The upper return path (910) is connected to each of the reception section (200), the medium thickness detection section (300), the deposit medium discrimination section (400), the temporary holding section (500), and the reject section (600), and can return the medium (2) between the reception section (200), the medium thickness detection section (300), the deposit medium discrimination section (400), the temporary holding section (500), and the reject section (600). In addition, the upper return path (910) is connected to the lower return path (920), and can return normal or abnormal withdrawal notes temporarily reserved in the temporary holding section (500) to the storage section (700), and can return abnormal withdrawal notes discriminated in the withdrawal medium discrimination section (800) to the temporary holding section (500).

[0068] The lower return path (920) is connected to the storage unit (700) and the withdrawal medium identification unit (800), so that normal notes stored in the storage unit (700) can be returned to be identified by the withdrawal medium identification unit (800). In addition, the lower return path (920) is connected to the upper return path (910), so that normal notes identified by the withdrawal medium identification unit (800) can be returned to the reception unit (200). In addition, the lower return path (920) can return normal notes or abnormal withdrawal notes temporarily held in the temporary holding unit (500) so that they can be stored in the storage unit (700), and can return abnormal withdrawal notes identified by the withdrawal medium identification unit (800) so that they can be temporarily held in the temporary holding unit (500).

[0069] The gate (930) is placed at a branch of the upper return path (910) or a branch of the lower return path (920), and switches the direction of the branch of the upper return path (910) or the branch of the lower return path (920), thereby allowing the medium to be properly returned.

[0070] The controller (1000) can control one or more of the reception unit (200), the medium thickness detection unit (300), the deposit medium discrimination unit (400), the temporary holding unit (500), the rejection unit (600), the storage unit (700), the withdrawal medium discrimination unit (800), and the return path (900). The controller (1000) can be implemented by a computing device including a microprocessor, and the implementation method thereof is obvious to those skilled in the art, so a further detailed description is omitted.

[0071] The controller (1000) can calculate the thickness of the medium (2) based on the vertical displacement of the thickness-sensing auxiliary roller (322) with respect to the thickness-sensing reference roller (321) detected by the roller displacement detecting unit (330). The controller (1000) is connected to the roller displacement detecting unit (330) to receive the vertical displacement of the thickness-sensing auxiliary roller (322) detected by the roller displacement detecting unit (330), and can calculate the thickness of the medium (2) based on the vertical displacement of the thickness-sensing auxiliary roller (322).

[0072] The controller (1000) can calculate the thickness of the medium (2) by subtracting the medium non-passing phase, which is the vertical displacement of the thickness-sensing auxiliary roller (322) in the medium non-passing state of the thickness-sensing roller unit (320), from the medium passing phase, which is the vertical displacement of the thickness-sensing auxiliary roller (322) in the medium passing state of the thickness-sensing roller unit (320). The medium non-passing phase can represent the concentricity of the thickness-sensing reference roller (321). In other words, the medium non-passing phase can represent the degree of eccentricity of the thickness-sensing reference roller (321), etc. In addition, the medium passing phase can represent the sum of the concentricity of the thickness-sensing reference roller (321) and the thickness of the medium (2). In other words, the medium passing phase can represent, for example, the sum of the degree of eccentricity of the thickness-sensing reference roller (321) and the thickness of the medium (2). Therefore, by subtracting the medium non-passing phase from the medium passing phase, the influence of the concentricity of the thickness detection reference roller (321) can be excluded from the medium passing phase. In other words, when detecting the thickness of a medium (2) such as a banknote, the detected thickness of the medium (2) can be corrected in consideration of the concentricity of the thickness detection reference roller (321). In addition, even if the concentricity of the thickness detection reference roller (321) is not good, the thickness of the medium (2) can be detected relatively precisely. In addition, even if the concentricity of the thickness detection reference roller (321) is not good, the medium (2) attached by tape (2-1), etc., can be detected.

[0073] The controller (1000) can receive a plurality of rotational positions of the thickness sensing reference roller (321) from the encoder (340) while the thickness sensing reference roller (321) rotates once, and can receive a media non-passing phase at a plurality of rotational positions of the thickness sensing reference roller (321) from the roller displacement detection unit (330). In addition, the controller (1000) can store a media non-passing phase at a plurality of rotational positions of the thickness sensing reference roller (321) while the thickness sensing reference roller (321) rotates once. In addition, the controller (1000) can receive a plurality of rotational positions of the thickness sensing reference roller (321) from the encoder (340), and can receive a media passing phase at a plurality of rotational positions of the thickness sensing reference roller (321) from the roller displacement detection unit (330). Additionally, the controller (1000) can store the media non-passing phase at multiple rotational positions of the thickness sensing reference roller (321).

[0074] The controller (1000) can determine one or more reference rotation positions among a plurality of rotation positions of the thickness detection reference roller (321) based on the point in time at which the medium (2) is detected by the medium detection sensor (310). In addition, the controller (1000) can calculate the thickness of the medium (2) by subtracting the medium non-passing phase at one or more reference rotation positions from the medium passing phase at one or more reference rotation positions.

[0075] As described above, the thickness detection separation distance (LT), which is the distance between the medium detection sensor (310) and the thickness detection roller unit (320), may be greater than the circumference of the thickness detection reference roller (321). In addition, in the medium detection step (S100), the medium detection sensor (310) detects the passage of the medium (2) and the medium (2) must be returned a distance longer than the circumference of the thickness detection reference roller (321) to reach the thickness detection roller unit (320). In addition, in the medium detection step (S100), the medium detection sensor (310) detects the passage of the medium (2) and the thickness detection reference roller (321) must rotate by a predetermined angle after one rotation before the roller displacement detection unit (330) can begin to detect the medium passage phase.

[0076] For this reason, the rotational position of the thickness detection reference roller (321) at the time when the medium (2) is detected by the medium detection sensor (310) and the rotational position of the thickness detection reference roller (321) at the time when the roller displacement detection unit (330) starts to detect the medium passing phase may be different. Therefore, in order to calculate the thickness of the medium (2) by subtracting the medium passing phase from the medium non-passing phase in the controller (1000), the rotational position of the thickness detection reference roller (321) at which the medium passing phase is detected must be matched with the rotational position of the thickness detection reference roller (321) at which the medium non-passing phase is detected. To this end, the controller (1000) may determine one or more reference rotational positions from among a plurality of rotational positions of the thickness detection reference roller (321) based on the time when the medium (2) is detected by the medium detection sensor (310).

[0077] For example, the rotational positions of the thickness detection reference roller (321) detected by the encoder (340) may be 45. In addition, the controller (1000) may sequentially set the rotational positions of the 45 thickness detection reference rollers (321) to rotational positions up to the 45th, with the rotational position of the thickness detection reference roller (321) at the time when the medium (2) is detected by the medium detection sensor (310) as the first rotational position. In addition, the detection of the medium non-passing phase in the roller displacement detection unit (330) may be performed from the first rotational position to the 45th rotational position of the thickness detection reference roller (321) while the medium (2) is detected by the medium detection sensor (310) and the thickness detection reference roller (321) rotates once. In addition, the detection of the medium passing phase in the roller displacement detection unit (330) may be performed after the detection of the medium non-passing phase, and the thickness detection reference roller (321) may be rotated from the 1st rotational position to the 11th rotational position and may start at the 11th rotational position. In other words, the thickness detection separation distance (LT) may be the sum of the circumference of the thickness detection reference roller (321) and the arc length of the thickness detection reference roller (321) for the rotation angle between the 1st rotational position and the 11th rotational position of the thickness detection reference roller (321).

[0078] In addition, if the rotational position of the thickness sensing reference roller (321) where the medium passing phase is detected is the 39th rotational position from the 11th rotational position of the thickness sensing reference roller (321), the controller (1000) can determine at least some of the 39th rotational positions from the 11th rotational position of the thickness sensing reference roller (321) as the reference rotational position. In addition, the controller (1000) can calculate the thickness of the medium (2) by subtracting the medium non-passing phase from the medium passing phase at at least some of the rotational positions from the 11th rotational position to the 39th rotational position of the thickness sensing reference roller (321) determined as the reference rotational position. For example, the 39th rotational position from the 11th rotational position of the thickness sensing reference roller (321) can be determined as the reference rotational position. In addition, the controller (1000) can start calculating the thickness of the medium (2) by subtracting the medium non-passing phase from the medium passing phase at the 11th rotational position of the thickness sensing reference roller (321). In addition, the controller (1000) can calculate the thickness of the medium (2) by subtracting the medium non-passing phase from the medium passing phase sequentially from the 11th rotational position of the thickness sensing reference roller (321) to the 39th rotational position of the thickness sensing reference roller (321).

[0079] Meanwhile, in the financial automation device (1), the concentricity of the thickness detection reference roller (321) can be measured before each financial transaction. In other words, in the financial automation device (1), the concentricity of the thickness detection reference roller (321) can be measured before each deposit or withdrawal of the medium (2).

[0080] In a financial automation device (1), before each financial transaction, the thickness detection reference roller (321) rotates, the encoder (340) detects multiple rotational positions of the thickness detection reference roller (321), and the roller displacement detection unit (330) detects the media non-passing phase at multiple rotational positions, so that the concentricity of the thickness detection reference roller (321) can be measured.

[0081] The controller (1000) can drive the roller drive unit to rotate the thickness detection reference roller (321) before each financial transaction. In addition, the encoder (340) detects multiple rotational positions of the thickness detection reference roller (321), and the roller displacement detection unit (330) detects the media non-passing phase at multiple rotational positions of the thickness detection reference roller (321), so that the concentricity of the thickness detection reference roller (321) can be measured. The media non-passing phase at multiple rotational positions of the thickness detection reference roller (321) detected by the roller displacement detection unit (330) is transmitted to the controller (1000), and the concentricity of the thickness detection reference roller (321) can be calculated and stored in the controller (1000).

[0082] For example, while the thickness sensing reference roller (321) rotates once, the encoder (340) can detect 45 rotational positions of the thickness sensing reference roller (321). In addition, the encoder (340) can detect 250 rotational positions of the thickness sensing reference roller (321), and the roller displacement detection unit (330) can detect the media non-passing phase at 250 rotational positions of the thickness sensing reference roller (321). In addition, the concentricity of the thickness sensing reference roller (321) can be repeated for every 45 rotational positions of the thickness sensing reference roller (321). Accordingly, the medium non-passing phase detected at 250 rotational positions of the thickness sensing reference roller (321) may include the medium non-passing phase at 5 concentric positions of the same thickness sensing reference roller (321) and 25 rotational positions of the thickness sensing reference roller (321). Accordingly, when the thickness sensing reference roller (321) rotates 25 more rotational positions, the first rotational position of the thickness sensing reference roller (321) at which the medium non-passing phase is detected may be the first rotational position.

[0083] Hereinafter, a method for controlling a financial automation device according to an embodiment of the present invention will be described with reference to FIGS. 4 to 10. The financial automation device control method (S1) can detect the thickness of a medium (2), such as a banknote, returned from a financial automation device (1). For example, when a medium inserted into the reception section (200) of the financial automation device (1) is separated into individual sheets and transported to a deposit medium identification section (400) through an upper return path (910) of a return path (900), the thickness of the medium (2) can be detected. Referring to FIG. 4, the financial automation device control method may include a medium detection step (S100), a medium non-passing phase detection step (S200), a medium passing phase detection step (S300), and a medium thickness calculation step (S400).

[0084] Referring to FIG. 5, in the medium detection step (S100), the medium detection sensor (310) can detect the passage of the medium (2). For example, in the medium detection step (S100), the passage of the medium (2) can be detected by the medium detection sensor (310) disposed in the upper return path (910) between the reception unit (200) and the deposit medium identification unit (400). The medium detection sensor (310) can be spaced apart from the thickness detection roller unit (320) including the thickness detection reference roller (321) and the thickness detection auxiliary roller (322) in the opposite direction of the return direction of the medium (2) by a thickness detection distance (LT). In addition, the thickness detection distance (LT) can be greater than the circumference of the thickness detection reference roller (321). Therefore, in the medium detection step (S100), the medium detection sensor (310) detects the passage of the medium (2), and the medium (2) must be returned a distance longer than the circumference of the thickness detection reference roller (321) to reach the thickness detection roller unit (320).

[0085] Referring to FIGS. 6 and 7, in the medium non-passing phase detection step (S200), the medium non-passing phase, which is the vertical displacement of the thickness-sensing auxiliary roller (322) with respect to the thickness-sensing reference roller (321), can be detected in the medium non-passing state of the thickness-sensing roller unit (320) in which the medium (2) does not pass between the thickness-sensing reference roller (321) and the thickness-sensing auxiliary roller (322). For example, the medium non-passing phase in the medium non-passing state of the thickness-sensing roller unit (320) can be detected in the roller displacement detection unit (330). The thickness-sensing reference roller (321) can be fixed to the body (100), and the thickness-sensing auxiliary roller (322) can be arranged on the upper side of the thickness-sensing reference roller (321) so as to be movable at least in the vertical direction. In addition, in the medium non-passing state of the thickness sensing roller unit (320), the thickness sensing auxiliary roller (322) and the thickness sensing reference roller (321) may come into contact with each other. This medium non-passing phase may indicate the concentricity of the thickness sensing reference roller (321). In other words, the medium non-passing phase may indicate the degree of eccentricity of the thickness sensing reference roller (321).

[0086] The medium non-passing phase detection step (S200) may be performed while the passage of the medium (2) is detected in the medium detection step (S100) and the medium (2) is returned to the thickness detection roller unit (320) including the thickness detection reference roller (321) and the thickness detection auxiliary roller (322). While the passage of the medium (2) is detected in the medium detection step (S100) and the medium (2) is returned to the thickness detection roller unit (320), the medium (2) may not pass between the thickness detection reference roller (321) and the thickness detection auxiliary roller (322). In other words, while the passage of the medium (2) is detected in the medium detection step (S100) and the medium (2) is returned to the thickness detection roller unit (320), the thickness detection roller unit (320) may be in a medium non-passing state. Additionally, the roller displacement detection unit (330) can detect the medium non-passing phase in the medium non-passing state of the thickness detection roller unit (320).

[0087] In the media non-passing phase detection step (S200), the encoder (340) placed on the thickness detection reference roller (321) can detect multiple rotational positions of the thickness detection reference roller (321) while the thickness detection reference roller (321) rotates once. For example, in the media non-passing phase detection step (S200), the encoder (340) can detect 45 rotational positions of the thickness detection reference roller (321) while the thickness detection reference roller (321) rotates once.

[0088] In addition, in the medium non-passing phase detection step (S200), the medium non-passing phase can be detected at multiple rotational positions of the thickness detection reference roller (321). As described above, the thickness detection separation distance (LT), which is the distance between the medium detection sensor (310) and the thickness detection roller unit (320), can be greater than the length of the circumference of the thickness detection reference roller (321). In addition, in the medium detection step (S100), the medium detection sensor (310) can detect the passage of the medium (2) and the thickness detection reference roller (321) can rotate once while the medium (2) is returned to the thickness detection roller unit (320). In addition, the encoder (340) can detect multiple rotational positions of the thickness detection reference roller (321), and the roller displacement detection unit (330) can detect the medium non-passing phase at multiple rotational positions of the thickness detection reference roller (321). For example, the media non-passing phase can be detected by the roller displacement detection unit (330) at 45 rotational positions of the thickness detection reference roller (321).

[0089] Referring to FIGS. 8 and 9, in the medium passage phase detection step (S300), the medium passage phase, which is the vertical displacement of the thickness-sensing auxiliary roller (322) with respect to the thickness-sensing reference roller (321), can be detected in the medium passage state of the thickness-sensing roller unit (320) in which the medium (2) passes between the thickness-sensing reference roller (321) and the thickness-sensing auxiliary roller (322). For example, the medium passage phase in the medium passage state of the thickness-sensing roller unit (320) can be detected in the roller displacement detection unit (330). This medium passage phase can represent the sum of the concentricity of the thickness-sensing reference roller (321) and the thickness of the medium (2). In other words, the medium passage phase can represent, for example, the sum of the eccentricity of the thickness-sensing reference roller (321) and the thickness of the medium (2).

[0090] In the medium passing phase detection step (S300), one or more reference rotation positions among multiple rotation positions of the thickness detection reference roller (321) can be determined based on the point in time at which the medium (2) is detected.

[0091] As described above, the thickness detection separation distance (LT), which is the distance between the medium detection sensor (310) and the thickness detection roller unit (320), may be greater than the circumference of the thickness detection reference roller (321). In addition, in the medium non-passing phase detection step (S200), the medium non-passing phase may be detected at multiple rotational positions of the thickness detection reference roller (321) as the thickness detection reference roller (321) rotates once, and the medium passing phase may not be detected immediately in the medium passing phase detection step (S300). In other words, the medium passing phase detection step (S300) may be started only when the medium passing phase detection step (S200) is ended and the thickness detection reference roller (321) is further rotated by a predetermined angle so that the medium (2) is returned until it reaches the thickness detection roller unit (320).

[0092] For example, the rotational positions of the thickness detection reference roller (321) detected by the encoder (340) may be 45. In addition, the rotational position of the thickness detection reference roller (321) at the time when the medium (2) is detected by the medium detection sensor (310) may be set as the first rotational position, and the rotational positions of the 45 thickness detection reference rollers (321) may be sequentially set to rotational positions up to the 45th rotational position. In addition, the detection of the medium passage phase in the roller displacement detection unit (330) may not start from the first rotational position of the thickness detection reference roller (321), but may start after the thickness detection reference roller (321) is further rotated to the 11th rotational position. In other words, the thickness sensing distance (LT) may be the sum of the circumference of the thickness sensing reference roller (321) and the arc length of the thickness sensing reference roller (321) for the rotation angle between the 1st rotation position and the 11th rotation position of the thickness sensing reference roller (321).

[0093] In addition, if the rotational position of the thickness sensing reference roller (321) where the media passing phase is detected is the 39th rotational position from the 11th rotational position of the thickness sensing reference roller (321), at least some of the 39th rotational positions from the 11th rotational position of the thickness sensing reference roller (321) can be determined as the reference rotational position.

[0094] Meanwhile, the determination of the reference rotation position may also be performed in the aforementioned medium non-passing phase detection step (S200). For example, in the medium non-passing phase detection step (S200), the previously determined reference rotation position may be determined as the reference rotation position. Furthermore, in the medium non-passing phase detection step (S200), the reference rotation position may be determined by considering the length of the medium (2) in the return direction and the thickness detection separation distance (LT).

[0095] Referring to Fig. 10, in the medium thickness calculation step (S400), the thickness of the medium (2) can be calculated by subtracting the medium passage phase from the medium non-pass phase. The medium non-pass phase can represent the concentricity of the thickness sensing reference roller (321). In other words, the medium non-pass phase can represent the degree of eccentricity of the thickness sensing reference roller (321), etc. In addition, the medium passage phase can represent the sum of the concentricity of the thickness sensing reference roller (321) and the thickness of the medium (2). In other words, the medium passage phase can represent, for example, the sum of the degree of eccentricity of the thickness sensing reference roller (321) and the thickness of the medium (2). Therefore, by subtracting the medium non-pass phase from the medium passage phase, the influence of the concentricity of the thickness sensing reference roller (321) can be excluded from the medium passage phase. In other words, when detecting the thickness of a medium (2) such as a banknote, the detected thickness of the medium (2) can be corrected by taking into account the concentricity of the thickness detection reference roller (321). In addition, even if the concentricity of the thickness detection reference roller (321) is not good, the thickness of the medium (2) can be detected relatively precisely. In addition, even if the concentricity of the thickness detection reference roller (321) is not good, the medium (2) attached by tape (2-1) or the like can be detected.

[0096] In the medium thickness calculation step (S400), the thickness of the medium (2) can be calculated by subtracting the medium passing phase and the medium non-passing phase at any one reference rotational position of the thickness detection reference roller (321). In order to calculate the thickness of the medium (2) by subtracting the medium passing phase from the medium non-passing phase, the rotational position of the thickness detection reference roller (321) where the medium passing phase is detected must match the rotational position of the thickness detection reference roller (321) where the medium non-passing phase is detected. For example, in the medium passing phase detection step (S300), the medium passing phase can be detected from the 11th rotational position of the thickness detection reference roller (321) to the 39th rotational position of the thickness detection reference roller (321). In addition, the 39th rotational position from the 11th rotational position of the thickness detection reference roller (321) can be determined as the reference rotational position. In addition, the thickness of the medium (2) can be calculated by subtracting the medium non-passing phase from the medium passing phase at the 11th rotational position of the thickness sensing reference roller (321). In addition, the thickness of the medium (2) can be calculated by subtracting the medium non-passing phase from the medium passing phase sequentially from the 11th rotational position of the thickness sensing reference roller (321) to the 39th rotational position of the thickness sensing reference roller (321).

[0097] As described above, according to the financial automation device and the financial automation device control method according to one embodiment of the present invention, when the thickness of a medium (2) such as a banknote is detected, the detected thickness of the medium (2) can be corrected in consideration of the concentricity of the thickness detection reference roller (321) used to detect the thickness of the medium (2). In addition, even if the concentricity of the thickness detection reference roller (321) is not good, there is an effect that the thickness of the medium (2) can be detected relatively precisely. In addition, even if the concentricity of the thickness detection reference roller (321) is not good, there is an effect that the medium (2) attached by tape (2-1) or the like can be detected.
