Description

Technical Field

[0001] This application belongs to the field of financial equipment technology, specifically relating to a banknote double-sided authentication instrument. Background Technology

[0002] In the financial sector and many industries involving the circulation and management of banknotes and coins, the authentication of banknotes and coins is a crucial step. Traditional methods of banknote and coin authentication often rely on manual visual inspection and simple tools, such as using a magnifying glass to examine printing details and watermark features. However, relying solely on manual authentication is not only inefficient but also difficult to guarantee accuracy, easily leading to misjudgments or omissions.

[0003] To improve the efficiency and accuracy of banknote authentication, automated banknote authentication equipment has emerged. However, some existing banknote authentication instruments mainly focus on detecting features on one side of the banknote, using various detection elements such as optical sensors and magnetic sensors to analyze the integrity of the pattern, anti-counterfeiting marks, and the distribution of magnetic ink on one side. But this single-side detection method has obvious limitations, because the anti-counterfeiting features of banknotes are distributed on both sides, and detecting only one side cannot comprehensively and accurately determine the authenticity of the banknote.

[0030] In the present application, unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection", "fixing" and the like should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0031] The preferred embodiments of the present application are described below in conjunction with the accompanying drawings, and it should be understood that the preferred embodiments described herein are only used to illustrate and explain the present application, and are not used to limit the present application.

[0032] For a better understanding of the present application, reference should be made to the following drawings in conjunction with the detailed description of the preferred embodiments of the present application. Figures 1 to 4As shown, according to the embodiments of the present application, a banknote double-side identification instrument is provided, which comprises a detection flow channel 100, the detection flow channel 100 is in a ring structure, the inlet and outlet of the detection flow channel 100 coincide at the same position to form a shared port 1001, a deflector plate 1 is rotatably arranged at the shared port 1001, the working state of the deflector plate 1 comprises a first state and a second state, when the deflector plate 1 works in the first state, the shared port 1001 is used for releasing the banknote to be detected into the detection flow channel 100, when the deflector plate 1 works in the second state, the shared port 1001 is used for releasing the banknote to be detected out of the detection flow channel 100; wherein, during the movement of the banknote to be detected in the detection flow channel 100, the banknote to be detected can rotate 180° around the axis of the detection flow channel 100, and after the rotation is completed, the banknote to be detected enters the detection flow channel 100 again, so that both sides of the banknote to be detected can be detected in the detection flow channel 100.

[0033] In this embodiment, the detection flow channel 100 in a ring structure, in combination with the shared port 1001 and the rotatable deflector plate 1, can make the banknote to be detected rotate 180° completely and enter the detection flow channel 100 again for detection of the other side, ensuring that all anti-counterfeiting features of the front and back sides of the banknote can be detected, avoiding the missed detection caused by single-side detection, effectively improving the accuracy of banknote identification, and reducing the risk of counterfeit currency flowing into the market. Further, after the banknote to be detected rotates 180° naturally in the detection flow channel 100 and enters the detection process again, the whole process is smooth and continuous, avoiding the trouble of manually turning over or using complex mechanical devices to transfer the banknote to be detected for detection of the other side in the traditional detection method, greatly improving the detection efficiency, and being especially suitable for occasions requiring a large number of banknote detections, such as bank and public transportation company ticket centers.

[0034] The detection flow channel 100 can be an elliptical ring structure or a square ring structure with rounded corners, etc., which can form a closed and continuous circulation path, so that the banknote to be detected can continuously move along a single circular path in the detection flow channel 100 and complete a series of detection actions, which is not limited in the present application. It should be noted that the detection flow channel 100 in a ring structure has unique advantages compared to the traditional straight-line detection path. For example, in a straight-line detection path, if the banknote to be detected needs to be detected on both sides, it is usually necessary to turn over the banknote to be detected after detecting one side and then send it into the detection area again through a complex transfer device, such as a mechanical arm, a conveyor belt, etc. This not only increases the complexity of the equipment, but also easily causes problems such as the banknote to be detected being stuck or deviating from the position. The detection flow channel 100 in a ring structure avoids the trouble of manually turning over or using complex mechanical devices to transfer the banknote to be detected for detection of the other side in the traditional detection method, greatly improving the detection efficiency.

[0035] Specifically, a driving mechanism can be arranged in the detection flow channel 100 of the annular structure, such as rollers uniformly distributed along the detection flow channel 100, which uses friction to push the bill to be detected to move steadily along the detection flow channel 100. It can be understood that, since the detection flow channel 100 is annular, the direction of the driving force acting on the bill to be detected during movement is always consistent with the tangent direction of the detection flow channel 100, so that the bill to be detected can maintain a relatively stable motion state, reducing the possibility of damage or detection error of the bill to be detected due to sudden change of direction.

[0036] In this embodiment, the inlet and the outlet of the detection flow channel 100 coincide to form a common port 1001. When the deflector plate 1 is in the first state, the common port 1001 is like an open door, allowing the bill to be detected to smoothly enter the detection flow channel 100. At this time, an external conveying device, such as a conveyor belt or a roller of a bill inlet, pushes the bill to be detected to the common port 1001, and the bill to be detected enters the detection flow channel 100 of the annular structure under the guidance of the deflector plate 1 to start the detection of the first side. When the bill to be detected completes the detection of one side and rotates 180° to prepare for the detection of the other side in the detection flow channel 100, it moves to the common port 1001 again. At this time, the deflector plate 1 switches to the second state, and the common port 1001 becomes the outlet for the bill to be detected to leave the detection flow channel 100. It should be noted that, in this embodiment, the inlet and the outlet of the detection flow channel 100 are arranged to coincide to form the common port 1001, which simplifies the overall structure of the device, reduces the need for additional bill inlets and outlets, and makes the device more compact and efficient.

[0037] Specifically, the switching between the first state and the second state of the deflector plate 1 can be realized by an electromagnet. That is, when the bill to be detected enters the detection flow channel 100, a detection signal will be triggered as the bill to be detected moves in the detection flow channel 100. For example, a photoelectric sensor arranged at a specific position of the detection flow channel 100 detects the passage of the bill to be detected, and the signal is transmitted to the control system. The control system determines the stage of the bill to be detected according to a preset program, and sends a power-on instruction to the electromagnet when the bill to be detected completes the detection in the flow channel and has rotated 180° around the axis. The electromagnet generates a magnetic force after being powered on, attracting the deflector plate 1 and causing the deflector plate 1 to rotate, so that it switches from the first state to the second state, ready for the bill to be detected to leave after completing the detection. It should be noted that this control method based on the electromagnet can quickly respond to the instructions of the control system, realize relatively accurate state switching, and can be flexibly adjusted in the control system according to different bill types and detection requirements to adapt to various detection scenarios.

[0038] In the embodiment, the electromagnet is a rotating electromagnet, and its unique rotating characteristics make the rotation control of the steering plate 1 more accurate and efficient. The stator part of the rotating electromagnet can generate a stable and controllable magnetic field through a reasonably designed electromagnetic coil and core when energized. When the control system issues an instruction, the current is passed into the coil of the rotating electromagnet, and the magnetic field generated thereby interacts with the rotor to accurately drive the rotor to rotate the steering plate 1, thereby realizing smooth switching from the first state to the second state.

[0039] Specifically, in the embodiment, at least two photoelectric sensors are provided, one of which is located between the common port 1001 and the external conveying device. When this photoelectric sensor is triggered, the rotating electromagnet drives the steering plate 1 to rotate in the counterclockwise direction, causing the steering plate 1 to switch to the first state of operation. The other photoelectric sensor is located in the detection flow channel 100. When this photoelectric sensor is triggered, the rotating electromagnet drives the steering plate 1 to rotate in the clockwise direction, causing the steering plate 1 to switch to the second state of operation.

[0040] In the embodiment, the 180° rotation of the bill to be detected around the axis in the detection flow channel 100 can be achieved according to the annular structure of the detection flow channel 100. For example, the annular detection flow channel 100 has at least two inclined guide surfaces. When the bill to be detected moves to this area, due to the action of the inclined guide surfaces, a lateral force is applied to one side of the bill to be detected, causing the bill to be detected to rotate around the axis of the detection flow channel 100 until it rotates 180° and exits the detection flow channel 100.

[0041] Specifically, when the bill to be detected enters the detection flow channel 100, it will first pass through a series of detection elements to detect the first side. These detection elements can include optical sensors for detecting the visual features of the bill such as patterns, colors, watermarks, etc.; magnetic sensors for detecting the distribution of magnetic ink on the bill; and thickness sensors for detecting whether the thickness of the bill meets the standard, etc. When the bill to be detected rotates 180° and reenters the detection flow channel 100, it will again pass through these detection elements for comprehensive detection of the other side. The advantage of this double-sided detection is that it can comprehensively and accurately identify the authenticity of the bill. Modern banknotes often have unique designs on both sides, and only by detecting both sides can the risk of false bills being mistaken for true bills be minimized. For example, some high-value banknotes may have color-changing ink printed patterns on the front, and special microtext or security lines on the back, and only through double-sided detection can the presence and correctness of these anti-counterfeiting features be fully verified.

[0042] In some possible implementation embodiments disclosed in the present application, the participants Figure 1 and Figure 2As shown, the banknote double-side identification instrument further comprises an in-out material multiplex flow channel 200, and the in-out material flow channel is connected with the detection flow channel 100 through a shared port 1001.

[0043] In this embodiment, the in-out material multiplex flow channel 200 is connected with the detection flow channel 100 through the shared port 1001, which simplifies the overall structure of the equipment. Compared with setting independent in-out material channels, the multiplex flow channel reduces the occupation of the internal space of the equipment.

[0044] The in-out material multiplex flow channel 200 needs to work with other components while being connected with the detection flow channel 100. For example, a driving wheel or a conveying belt and the like can be arranged near the shared port 1001, and the driving wheel or the conveying belt and the like provides power for the movement of the banknote to be detected between the multiplex flow channel and the detection flow channel 100. When the banknote to be detected enters the in-out material multiplex flow channel 200 from the outside, the driving wheel starts to work to smoothly push the banknote to the shared port 1001 and then to the detection flow channel 100. After the banknote to be detected is detected, the driving wheel or other driving devices arranged at the outlet of the multiplex flow channel pulls the banknote to be detected from the detection flow channel 100 to the in-out material multiplex flow channel 200 through the shared port 1001, and finally sends the banknote out of the equipment.

[0045] Specifically, when the banknote to be detected enters the banknote double-side identification instrument, the entrance end of the in-out material multiplex flow channel 200 is first contacted. The entrance end can be provided with a guide device, such as an inclined slide plate or a guide edge with a certain arc, so as to facilitate the banknote to be detected to smoothly enter the multiplex flow channel without deviation or jamming. Once the banknote to be detected enters the in-out material multiplex flow channel 200, the banknote to be detected moves along the in-out material multiplex flow channel 200 to the shared port 1001 under the action of a driving device, such as a roller or a belt. At the same time, a preliminary detection sensor, such as a thickness sensor or a photoelectric sensor, can be arranged in the in-out material multiplex flow channel 200 during the banknote feeding process, to detect whether the banknote to be detected is normally entered or whether there is an abnormal condition that multiple banknotes to be detected are simultaneously entered.

[0046] In some possible implementation embodiments disclosed in the present application, Figure 1 and Figure 2 As shown, the banknote double-side identification instrument further comprises a banknote supporting table 2, which is located on the side of the in-out material multiplex flow channel 200 away from the detection flow channel 100, and the banknote supporting table 2 is connected with the in-out material multiplex flow channel 200.

[0047] In this embodiment, the banknote support platform 2 is located on the side of the inlet / outlet reuse channel 200 away from the detection channel 100, providing stable support for the banknotes to be tested. When the banknotes to be tested move within the inlet / outlet reuse channel 200, especially during entry and exit, they may sway or tilt due to various factors such as fluctuations in transmission power or uneven weight distribution. The banknote support platform 2 acts like a solid base, ensuring that the banknotes to be tested remain relatively stable during transmission.

[0048] The connection between the banknote holding platform 2 and the inlet / outlet reuse channel 200 is fundamental to its function. In practical applications, this connection can be made with a smooth transition or a transition from high to low along the direction of banknote movement to ensure that banknotes can smoothly transition from the banknote holding platform 2 into the inlet / outlet reuse channel 200 without jamming or collision at the connection.

[0049] Specifically, a section of the banknote holding platform 2 away from the inlet and outlet reuse channel can be equipped with an inclined sliding plate or a guide edge with a certain curvature. The purpose is to facilitate the smooth entry of the banknotes to be tested into the reuse channel without deviation or jamming.

[0050] In some possible implementations disclosed in this application, participants Figure 1 and Figure 2 As shown, the banknote double-sided authentication instrument also includes a first sensor 3, a second sensor 4, and a third sensor 5. The first sensor 3 is disposed on the banknote holding platform 2, the second sensor 4 is disposed on the inlet / outlet reuse channel 200, and the third sensor 5 is disposed on the detection channel 100. The first sensor 3, the second sensor 4, and the third sensor 5 are all used to sense the position information of the banknote to be tested. When the first sensor 3 and / or the second sensor 4 are triggered, the steering plate 1 switches to the first state of operation. When the third sensor 5 is triggered, the steering plate 1 switches to the second state of operation.

[0051] In this embodiment, by setting a first sensor 3, a second sensor 4, and a third sensor 5 in the banknote holding platform 2, the inlet / outlet reuse channel 200, and the detection channel 100 respectively, the state of the banknote to be tested in different positions can be accurately sensed, making the switching of the working state of the steering plate 1 more accurate.

[0052] The first sensor 3 can be either present or absent. In practical applications, the first sensor 3 is installed on the banknote holding platform 2, and its position is close to the starting end of the banknote to be tested entering the inlet / outlet reuse channel 200. It can effectively sense the banknote to be tested as soon as it is placed on the banknote holding platform 2 and is about to enter the channel.

[0053] The second sensor 4 can be a pair of photoelectric sensors. In practical applications, the second sensor 4 is arranged inside the input and output multiplex flow channel 200, and is located in a region where the to-be-tested banknote has moved for a short time but has not yet deeply entered the input and output multiplex flow channel 200 after entering the input and output multiplex flow channel 200, and can accurately detect the passing of the to-be-tested banknote in the input and output multiplex flow channel 200.

[0054] The third sensor 5 can also be a pair of photoelectric sensors. In practical applications, the third sensor 5 is arranged in the detection flow channel 100 close to the common port 1001, and can detect the position of the to-be-tested banknote in time after the to-be-tested banknote enters the detection flow channel 100, so as to trigger the switching of the deflection plate 1 and enable the to-be-tested banknote to smoothly leave the detection flow channel 100 after detection.

[0055] Specifically, when the user places the to-be-tested banknote on the banknote placing table 2, the first sensor 3 first detects. If the first sensor 3 detects the presence of the to-be-tested banknote, the first sensor 3 immediately sends a signal to the control system. After receiving the signal, the control system determines that the to-be-tested banknote is in an initial entering state, and then issues an instruction to switch the deflection plate 1 to the first state, opens the channel between the input and output multiplex flow channel 200 and the detection flow channel 100, and prepares to receive the to-be-tested banknote. At this time, if the to-be-tested banknote is slightly delayed or stalled when entering the input and output multiplex flow channel 200, the second sensor 4 will further monitor. Once the second sensor 4 also detects that the to-be-tested banknote enters the input and output multiplex flow channel 200, the second sensor 4 will send a confirmation signal to the control system again, to ensure that the deflection plate 1 remains in the first state, so that the to-be-tested banknote can smoothly enter the detection flow channel 100 for detection. For example, in some cases, the to-be-tested banknote may not enter the input and output multiplex flow channel 200 in time due to improper placement or slight external interference, and the detection and signal feedback of the second sensor 4 can ensure the reliability of the banknote feeding process and avoid the premature closing of the channel due to misjudgment of the deflection plate 1. After the to-be-tested banknote enters the detection flow channel 100, the third sensor 5 begins to play a role. At this time, the third sensor 5 sends a signal to the control system, and after receiving the signal, the control system immediately issues an instruction to switch the deflection plate 1 to the second state, so that the to-be-tested banknote can smoothly leave the detection flow channel 100 after detection.

[0056] In some possible implementation embodiments of the present disclosure, the deflection plate 1 is arranged in the input and output multiplex flow channel 200, and the deflection plate 1 is configured to be rotatable in two opposite directions. Figure 1 Figure 2 As shown in the figure, the input and output multiplex flow channel 200 is provided with an input and output conveying assembly 6, and the input and output conveying assembly 6 includes an input and output counter-rotating wheel 61 and an input and output floating wheel 62. The input and output counter-rotating wheel 61 is configured to be rotatable in two opposite directions.

[0057] ​In this embodiment, the in-out material pair of rotating wheels 61 can rotate in two opposite directions, which makes the device flexible to control the in-out of the test banknotes. When the test banknotes need to enter the detection flow channel 100, the in-out material pair of rotating wheels 61 can rotate in the forward direction to stably transport the test banknotes from the in-out material multiplex flow channel 200 to the detection flow channel 100; and when the test banknotes complete the detection, the in-out material pair of rotating wheels 61 can rotate in the reverse direction to pull the test banknotes from the detection flow channel 100 back to the in-out material multiplex flow channel 200, and then send out of the device.

[0058] In actual application, the in-out material pair of rotating wheels 61 rotates counterclockwise to push the test banknotes from the in material port to the detection flow channel 100 along the in-out material multiplex flow channel 200, to realize the in material operation of the banknotes; and rotates clockwise to transport the test banknotes that have completed the detection from the detection flow channel 100 to the outside along the in-out material multiplex flow channel 200, to complete the out material process.

[0059] Specifically, the first sensor 3, the second sensor 4 and the third sensor 5 are also used to control the rotating direction of the in-out material pair of rotating wheels 61, when the first sensor 3 and / or the second sensor 4 triggers, the in-out material pair of rotating wheels 61 rotates counterclockwise, and when the third sensor 5 triggers, the in-out material pair of rotating wheels 61 rotates clockwise.

[0060] In actual application, the in-out material pair of rotating wheels 61 provides the main driving force to push the test banknotes forward, and the in-out material floating wheel 62 provides the lateral pressure to stably limit the test banknotes between the two.

[0061] Specifically, the in-out material conveying assembly 6 further comprises an in-out material driving motor, which is connected with the in-out material pair of rotating wheels 61. In actual application, the first sensor 3, the second sensor 4 and the third sensor 5 are electrically connected with the in-out material driving motor. When the first sensor 3 or the second sensor 4 detects the test banknote signal and transmits to the control system, the control system will drive the in-out material driving motor to rotate the in-out material pair of rotating wheels 61 in the counterclockwise direction according to the preset program, so as to start the in material process. When the third sensor 5 triggers, the control system instructs the in-out material driving motor to reverse, so that the in-out material pair of rotating wheels 61 rotates clockwise to complete the out material action.

[0062] In some possible implementation embodiments of the present application, the in-out material pair of rotating wheels 61 can rotate in two opposite directions, which makes the device flexible to control the in-out of the test banknotes. When the test banknotes need to enter the detection flow channel 100, the in-out material pair of rotating wheels 61 can rotate in the forward direction to stably transport the test banknotes from the in-out material multiplex flow channel 200 to the detection flow channel 100; and when the test banknotes complete the detection, the in-out material pair of rotating wheels 61 can rotate in the reverse direction to pull the test banknotes from the detection flow channel 100 back to the in-out material multiplex flow channel 200, and then send out of the device. Figure 1 and Figure 2As shown, the detection flow channel 100 includes a curved section and a straight section, the curved section is provided with a curved conveying assembly 7, and the straight section is provided with a straight conveying assembly 8; wherein the curved conveying assembly 7 includes a curved counter-rotating wheel 71 and a curved floating wheel 72, and the straight conveying assembly 8 includes a straight counter-rotating wheel 81 and a straight floating wheel 82, and the curved counter-rotating wheel 71 and the straight counter-rotating wheel 81 are configured to rotate in a single direction.

[0063] The curved counter-rotating wheel 71 and the curved floating wheel 72 in the curved conveying assembly 7 cooperate, the curved counter-rotating wheel 71 provides driving force to move the to-be-detected banknote in the curved section, and the curved floating wheel 72 provides lateral pressure to stably restrict the to-be-detected banknote therebetween. This is like giving the banknote a stable "hold" force at the curved section, avoiding the to-be-detected banknote from deviating from the normal running track due to centrifugal force and other factors, and ensuring that the to-be-detected banknote can move smoothly on the curved path.

[0064] Specifically, the curved counter-rotating wheel 71 is configured to rotate in a single direction, so that the to-be-detected banknote can be continuously pushed to move forward along the curved detection flow channel 100 at the curved section. It can be understood that the to-be-detected banknote moves in the annular detection flow channel 100 and inevitably passes through the curved section, and the curved counter-rotating wheel 71 configured to rotate in a single direction can well adapt to the shape of the curved path, ensure the to-be-detected banknote to smoothly pass through the curved area, and provide a stable premise for subsequent detection and rotation.

[0065] The straight counter-rotating wheel 81 and the straight floating wheel 82 in the straight conveying assembly 8 cooperate, and the principle is similar to that of the curved conveying assembly 7, the straight counter-rotating wheel 81 provides power to move the to-be-detected banknote in the straight section, and the straight floating wheel 82 provides lateral pressure to stabilize the to-be-detected banknote. Therefore, it can be ensured that the to-be-detected banknote can maintain a straight motion state in the straight section and will not deviate or shake, so that the to-be-detected banknote can accurately pass through various detection elements arranged in the straight section, and the detection accuracy is ensured.

[0066] Specifically, the straight counter-rotating wheel 81 rotates in a single direction, which can efficiently push the to-be-detected banknote to move forward in the straight section. It can be understood that since modern banknotes have various anti-counterfeit features to be detected, the straight section can be provided with optical sensors, magnetic sensors, thickness sensors and other detection elements, and the single-direction stable rotation of the straight counter-rotating wheel 81 can make the to-be-detected banknote pass through these detection elements at a suitable speed and state, avoiding detection omission or error caused by unstable transmission, thereby improving the detection efficiency.

[0067] It should be noted that, in this embodiment, the annular detection channel 100 has two curved sections and two straight sections. Each of the two straight sections is equipped with a linear conveying assembly 8, and each of the two curved sections is equipped with two curved conveying assemblies 7. That is, there are a total of four curved conveying assemblies 7 and two linear conveying assemblies 8. Furthermore, in this embodiment, the four curved conveying assemblies 7 and the two linear conveying assemblies 8 are driven by the same main drive motor.

[0068] In some possible implementations disclosed in this application, participants Figure 1 and Figure 2 As shown, the straight section is also equipped with an image acquisition device 9 and a magnetic acquisition device 10. The image acquisition device 9 is used to acquire the image information of the banknote to be tested, and the magnetic acquisition device 10 is used to detect the magnetic information of the banknote to be tested.

[0069] In some possible implementations disclosed in this application, participants Figure 1 and Figure 2 As shown, the straight section is also provided with an image acquisition pressure roller 11 and a magnetic acquisition pressure roller 12. The image acquisition pressure roller 11 is set facing the image acquisition device 9 and is used to apply pressure to the banknote to be tested in the direction of the image acquisition device 9. The magnetic acquisition pressure roller 12 is set facing the magnetic acquisition device 10 and is used to apply pressure to the banknote to be tested in the direction of the magnetic acquisition device 10.

[0070] In this embodiment, by setting the image acquisition pressure roller 11, image blurring or distortion caused by wrinkles, bends, or partial warping of the banknote under test can be reduced. By setting the magnetic acquisition pressure roller 12, it can be ensured that the magnetic collector 10 can more accurately detect the magnetic field information of the magnetic ink on the banknote.

[0071] In some possible implementations disclosed in this application, participants Figure 1 and Figure 2 As shown, the banknote double-sided authentication instrument also includes an outer shell 13 and an inner shell 14, with a detection flow channel 100 formed between the outer shell 13 and the inner shell 14.

[0072] In this embodiment, a detection channel 100 is formed between the outer shell 13 and the inner shell 14. This double-shell structure provides a stable physical boundary for the detection channel 100. Compared with a single-wall structure, it is more resistant to the influence of external factors on the shape of the detection channel 100.

[0073] In the above embodiments, participants Figure 1 and Figure 2 Figure 3 Figure 4 As shown, the outer shell 13 includes a first half shell 131 and a second half shell 132. The first half shell 131 and the second half shell 132 are rotatably connected by a rotating connector 15. The rotating connector 15 is also rotatably connected to the inner shell 14.

[0074] In this embodiment, by rotating the first half shell 131, the second half shell 132 and the inner shell 14, the internal structure of the device can be quickly opened, and the card currency position can be directly contacted, thereby shortening the time required to handle the card currency problem and reducing the downtime of the device.

[0075] The rotating connection 15 can be a rotating shaft.

[0076] Specifically, in actual application, when the first half shell 131 and the inner shell 14 are stuck with the card currency, the first half shell 131 can be rotated to directly expose the card currency area, so that the operator can quickly check the card currency condition and accurately clean or adjust, so that the to-be-tested banknote can smoothly separate from the stuck position; when the second half shell 132 and the inner shell 14 are stuck with the card currency, the first half shell 131 and the inner shell 14 can be rotated to fully open the internal space of the device on this side, so that the card currency point can be approached from multiple angles, whether with tools or manual handling, the card currency failure can be more efficiently eliminated, the downtime of the device caused by the card currency is reduced, and the continuity and efficiency of the banknote identification work are ensured.

[0077] It is easy for those skilled in the art to understand that the above advantageous modes can be freely combined and superimposed without conflict.

[0078] The above is only a preferred embodiment of the present application, and does not limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application. The above is only a preferred embodiment of the present application, and should be noted that for ordinary skilled in the art, without departing from the technical principles of the present application, a number of improvements and variations can be made, which should be considered as the protection scope of the present application.
