[0029] The card scanning device is used to read the information of card media such as identity cards and bank cards. In the related art, the card scanning device is provided with a card scanning channel, and a roller assembly is arranged in the card scanning channel. The card is clamped by the rollers to drive the card to move, so as to complete the reading of the card information. However, in this method, the card is clamped between the upper and lower rollers and is prone to jitter during movement, or multiple sets of rollers are provided, and the card is prone to being blocked and stopped when passing from one set of rollers to the next set of rollers. All of these are likely to cause phenomena such as image smear and blurring, affecting the image quality.

[0030] Please refer to Figures 1 to 6 , the present utility model provides a card scanner 100 for reading card information. The card scanner 100 includes: a frame assembly 10, the frame assembly 10 includes an upper frame 11 and a lower frame 12, the upper frame 11 is connected to the lower frame 12, and a scanning channel 13 is provided between the upper frame 11 and the lower frame 12; a roller assembly 20, the roller assembly 20 includes a first roller member 21 and a second roller member 22, the first roller member 21 is movably installed on the upper frame 11 and partially extends into the scanning channel 13, the second roller member 22 is movably installed on the lower frame 12 and partially extends into the scanning channel 13, and the first roller member 21 and the second roller member 22 are arranged oppositely; and a holding assembly 30, the holding assembly 30 includes a first holding member 31 and a second holding member 32, the first holding member 31 is arranged on the upper frame 11 and extends into the scanning channel 13, the second holding member 32 is arranged on the lower frame 12 and extends into the scanning channel 13, and the first holding member 31 and the second holding member 32 respectively abut against the first surface and the second surface of the card, so that the card is sent out from the scanning channel 13 along the first holding member 31 and the second holding member 32.

[0031] Specifically, the ID card scanner 100 is used to scan and read card information. The ID card scanner 100 includes a frame assembly 10, a roller assembly 20, and a holding assembly 30. The frame assembly 10 is used to install internal components. The frame assembly 10 includes an upper frame 11 and a lower frame 12. A scanning channel 13 is formed between the upper frame 11 and the lower frame 12. The scanning channel 13 is used for the card to pass through, so as to scan and read the card information. The roller assembly 20 is used to drive the card to move in the scanning channel 13. The holding assembly 30 is used to hold against the surface of the card to make the card move stably in the scanning channel 13.

[0032] The upper frame 11 and the lower frame 12 enclose to form the scanning channel 13. The first roller member 21 and the second roller member 22 are respectively movably installed on the upper frame 11 and the lower frame 12, and are oppositely arranged and partially extend into the scanning channel 13. When the card moves in the scanning channel 13 and passes through the first roller member 21 and the second roller member 22, since the two roller members can move, they can move according to the holding pressure generated by the card on the two roller members, and the card can easily pass through the first roller member 21 and the second roller member 22.

[0033] The first roller member 21 is movably installed on the upper frame 11. The specific installation method can be to support it through a spring. When the card passes through, the first roller member 21 will move by compressing the spring. After the card moves away, it can be reset. It can also be to set a slide rail or a chute so that the first roller member 21 can slide up and down in the track. The specific installation method can be selected according to actual needs. Similarly, the installation method of the second roller member 22 is similar to that of the first roller member 21 and will not be elaborated here.

[0034] The first roller member 21 and the second roller member 22 are oppositely arranged, so they can hold against the two surfaces of the card and drive the card to move. In a specific embodiment, each roller member includes a rotating shaft and two rollers. The two rollers are rotatably connected to both ends of the rotating shaft. The rollers are movably installed on the upper frame 11. Setting two rollers can better fit the card and drive the card to move smoothly.

[0035] The specific structure of the first holding member 31 can be a pressing plate, or a roller or a ball array, or a wedge-shaped strip. The specific structure can be selected according to actual needs, as long as it can contact the surface of the card, provide support, and ensure that the card remains stable during movement. Similarly, the specific structure of the second holding member 32 is similar to that of the first roller member 21 and will not be elaborated here.

[0036] Due to the provision of the first abutting member 31 and the second abutting member 32, the height of the movement path of the card is actually smaller than the height of the scanning path 13. The first abutting member 31 and the second abutting member 32 can provide a constant movement space when the card passes through, ensuring the stability of the card during movement and improving the reliability and working efficiency of the entire card scanning device.

[0037] In the technical solution of the present utility model, by providing the first abutting member 31 and the second abutting member 32 on the upper frame 11 and the lower frame 12, and respectively abutting the first abutting member 31 and the second abutting member 32 against the first surface and the second surface of the card, the pressure can be more evenly distributed, reducing the jitter of the card when passing through the scanning path 13, providing a constant movement space when the card passes through, contributing to maintaining the stability of the card during movement, enabling the card to be smoothly sent out from the scanning path 13. Stable card transmission can reduce the blurring and ghosting phenomena during image acquisition, improve the quality of the scanned image, and ensure the accuracy and integrity of information reading. At the same time, the design of the first abutting member 31 and the second abutting member 32 can improve the scanning accuracy and ensure the accuracy of information recognition; the first roller member 21 and the second roller member 22 only partially extend into the scanning path 13 and are movable within the scanning path 13, enabling the card to easily pass through the first roller member 21 and the second roller member 22, avoiding jitter or blocked pauses, and generating a relatively clear image with high scanning image quality.

[0038] In an embodiment of the present utility model, the first abutting member 31 includes a first rib 311, the second abutting member 32 includes a second rib 321, and the first rib 311 and the second rib 321 are disposed opposite to each other.

[0039] Specifically, the position of the rib can be set in the middle of the scanning path 13 or on both sides of the scanning path 13, and the specific position can be selected according to actual needs. The rib structure is simple, with low cost, and is easy to clean dust or foreign objects, and the maintenance is also more convenient.

[0040] Such as Figure 4 and Figure 5 , the contact area of the rib with respect to the entire card surface is relatively small, and the frictional force between the card and the first rib 311 and the second rib 321 is relatively small, which can reduce the wear of the card surface.

[0041] The first rib 311 and the second rib 321 respectively abut against the front and back surfaces of the card, forming stable support points, making it difficult for the card to deflect or jitter when passing through the path. Due to the relatively concentrated support provided by the rib, the card can pass through the scanning path 13 more quickly, improving the efficiency.

[0042] In addition, such as Figure 5 and Figure 6The front and rear ends of the two ribs are provided with guiding curved surfaces. This design can reduce the resistance when the card enters and leaves the scanning channel 13, helping the card to enter and exit more easily, providing a smooth transition, reducing the jamming caused by sharp edges, and improving transmission efficiency.

[0043] In an embodiment of the present utility model, four first ribs 311 are provided, and six second ribs 321 are provided. The four first ribs 311 are evenly spaced on the top wall of the scanning channel 13, and the six second ribs 321 are spaced on the bottom wall of the scanning channel 13; the two outermost first ribs 311 are opposite to the two outermost second ribs 321, and the two middle second ribs 321 are opposite to the two middle first ribs 311.

[0044] It is worth noting that Figure 4 By arranging the two outermost first ribs 311 opposite the two outermost second ribs 321, they can support the card surface from both sides, providing firm support at the card's edges and preventing it from shifting or tilting during movement. By arranging the two middle second ribs 321 opposite the two middle first ribs 311, the center of the card is further reinforced, ensuring it remains flat throughout the scanning process. This design distributes the supporting force on the card more evenly, reducing the risk of bending or damage due to excessive force at a single point.

[0045] Increasing the number of ribs provides more support points on both sides of the card, ensuring a more even distribution of pressure across the card surface. This improves the card's stability as it passes through the scanning channel 13, reduces jitter, and enhances image quality and information reading accuracy. Furthermore, a reasonable layout minimizes contact area, achieving better performance.

[0046] In an embodiment of the present invention, the upper frame 11 is rotatably connected to the lower frame 12; the card scanner 100 also includes a locking assembly (not shown in the figure), and the locking assembly includes a first locking member (not shown in the figure) and a second locking member (not shown in the figure), the first locking member is arranged on the upper frame 11, and the second locking member is arranged on the lower frame 12, and the first locking member and the second locking member are arranged in a coordinated manner.

[0047] Specifically, through the rotation connection, the upper frame 11 can be opened relative to the lower frame 12, which facilitates cleaning, inspection and maintenance of the internal structure of the equipment, reducing the complexity of disassembly.

[0048] The locking component can ensure that the upper frame 11 and the lower frame 12 are tightly closed during the operation of the device, prevent potential safety hazards caused by accidental opening, and make installation and disassembly simpler and faster. The operation can be completed without tools, improving work efficiency.

[0049] In an embodiment of the present utility model, the first locking component includes a buckle 41, the buckle 41 protrudes from the upper frame 11, the second locking component includes a slot 42, the slot 42 is provided on the lower frame 12, and the buckle 41 is arranged in cooperation with the slot 42; and / or, the first locking component includes a first magnetic block (not shown in the figure), the first magnetic block is arranged on the upper frame 11, the second locking component further includes a second magnetic block (not shown in the figure), the second magnetic block is arranged on the lower frame 12, and the first magnetic block is arranged in cooperation with the second magnetic block.

[0050] Specifically, the cooperation structure of the buckle 41 and the slot 42 is simple and highly reliable. The locking can be completed by simply aligning the buckle 41 with the slot 42 and pressing gently. When unlocking, only a certain force needs to be applied to easily separate them, and the production cost is relatively low. Moreover, the tight cooperation between the buckle 41 and the slot 42 can prevent accidental opening during the use of the device due to vibration or other reasons.

[0051] By setting the first magnetic block and the second magnetic block, there is an attractive force between them, which can help users align and lock the two parts together more quickly, improving the operation convenience. The first magnetic block and the second magnetic block can be hidden inside the device without damaging the overall appearance design of the device.

[0052] During use, only the buckle 41 and the slot 42 can be set, or only the first magnetic block and the second magnetic block can be set, or the two methods can be combined.

[0053] In one embodiment, both the buckle 41 and the slot 42 and the first magnetic block and the second magnetic block are provided, and the first magnetic block and the second magnetic block are hidden inside the device. A dual locking mechanism can be provided to further improve safety. The automatic alignment of the two magnetic blocks plus the mechanical locking of the buckle 41 makes the connection more reliable and the operation simple.

[0054] Through the locking of the buckle 41 and the slot 42, and the magnetic attraction of the first magnetic block and the second magnetic block, it can be ensured that the upper frame 11 and the lower frame 12 are tightly combined, thereby reducing the unstable movement of the card caused by the loosening of the frame, reducing the interference suffered by the card during movement, and improving the smoothness of card transmission.

[0055] A stable frame helps to maintain the precise position of the card during transmission, can reduce image smear or blurring caused by frame vibration, and improve the quality of reading card information.

[0056] In an embodiment of the present utility model, the roller assembly 20 also includes a third roller member 23 and a fourth roller member 24. The third roller member 23 is movably mounted on the upper frame 11 and partially extends into the scanning channel 13. The third roller member 23 and the first roller member 21 are spaced apart along the length direction of the upper frame 11; the fourth roller member 24 is movably mounted on the lower frame 12 and partially extends into the scanning channel 13. The fourth roller member 24 and the second roller member 22 are spaced apart along the length direction of the lower frame 12; the third roller member 23 and the fourth roller member 24 are arranged opposite to each other.

[0057] It is worth noting that Figure 3 A third roller member 23 and a fourth roller member 24 are also provided. The setting of multiple groups of roller members can ensure that the card always remains stable during the transmission process. Multi-point support can reduce the deviation or jitter of the card. Through multiple relatively arranged roller members, the card can be clamped in the middle, so that the pressure is evenly distributed at different positions of the card, reducing the problem of image blur or inaccurate information reading caused by card jitter, and improving the stability and accuracy of the card transmission process.

[0058] In the embodiment of the present invention 3, the card scanner 100 further includes a scanning component 50, and the scanning component 50 includes a first scanning part 51 and a second scanning part 52. The first scanning part 51 is arranged on the upper frame 11, and the second scanning part 52 is arranged on the lower frame 12. The first scanning part 51 and the second scanning part 52 are arranged opposite to each other.

[0059] Specifically, as shown in the figure, the scanning component 50 is arranged near the exit position of the scanning channel 13. By arranging the first scanning part 51 and the second scanning part 52 relative to each other, it can ensure that the document is scanned from two directions, allowing information collection on both sides to be completed in one pass, thereby improving work efficiency.

[0060] The design of the upper and lower frames 11 and 12 provides enhanced mechanical stability, ensuring long-term reliability and consistency. The first and second abutments 31 and 32, in conjunction with the scanning assembly 50, ensure clearer, higher-resolution card images scanned by the scanning assembly 50 without smearing. In one embodiment, the scanning assembly 50 can recognize English characters as small as 0.25 mm.

[0061] In an embodiment of the present utility model, the roller assembly 20 further includes a fifth roller member 25 and a sixth roller member 26. The fifth roller member 25 is movably installed on the upper frame 11 and partially extends into the scanning channel 13. The fifth roller member 25 and the third roller member 23 are arranged at intervals along the length direction of the upper frame 11 and are disposed on both sides of the first scanning member 51; the sixth roller member 26 is movably installed on the lower frame 12 and partially extends into the scanning channel 13. The sixth roller member 26 and the fourth roller member 24 are arranged at intervals along the length direction of the lower frame 12 and are disposed on both sides of the second scanning member 52; the fifth roller member 25 and the sixth roller member 26 are oppositely arranged.

[0062] Specifically, two sets of upper and lower roller members are provided on both sides of the scanning assembly 50, which can better guide the card through the scanning channel 13, ensure that it reaches the scanning position smoothly and accurately, avoid the situation of card jamming or blocking during the scanning process, and improve the scanning accuracy.

[0063] Setting multiple roller members at different positions on the upper frame 11 and the lower frame 12 can increase the stability and reliability of the entire system. Especially in the case of processing a large number of consecutive card inputs, it can ensure that each card can be processed consistently.

[0064] In an embodiment of the present utility model, the distance that the first roller member 21 protrudes from the scanning channel 13 is 2 mm to 4 mm, and the distance that the second roller member 22 protrudes from the scanning channel 13 is 2 mm to 4 mm; the distance that the third roller member 23 protrudes from the scanning channel 13 is 2 mm to 4 mm, and the distance that the fourth roller member 24 protrudes from the scanning channel 13 is 2 mm to 4 mm; the distance that the fifth roller member 25 protrudes from the scanning channel 13 is 2 mm to 4 mm, and the distance that the sixth roller member 26 protrudes from the scanning channel 13 is 2 mm to 4 mm.

[0065] It should be noted that each group of roller members protrudes 2 mm to 4 mm from the wall surface of the scanning channel 13. Within this distance range, the roller members can effectively contact and guide the card through the scanning channel 13, ensuring that the card can move smoothly and reducing the risk of jamming; the distance of 2 mm to 4 mm can not only ensure good contact between the roller members and the card, but also not exert too much pressure on the card, thereby reducing the wear or damage of the card when passing through.

[0066] In addition, the thickness of a standard bank card or ID card is about 0.7 mm. However, considering some possible special cards or thick cards, the protruding distance of 2 mm to 4 mm can adapt to the card thickness change within a certain range.

[0067] By cooperating with the supporting assembly 30 and the roller assembly 20, the roller assembly 20 can apply appropriate contact pressure to the card to prevent the card from getting stuck and keep the card flat during scanning. The supporting assembly 30 prevents the card from bending or tilting, thereby improving the quality and clarity of the scanned image.

[0068] In an embodiment of the present invention, a guide groove 131 is provided at the entrance of the scanning channel 13 , and a circumferential dimension of the guide groove 131 gradually decreases from the entrance toward the exit of the scanning channel 13 .

[0069] Specifically, by setting a guide groove 131 at the entrance of the scanning channel 13, when inserting the card, there is no need to align the channel entrance with particular precision. The guide groove 131 can help the card adjust its position and guide the card to smoothly enter the scanning channel 13, avoiding the card from getting stuck or skewed at the entrance, thereby reducing the jamming phenomenon.

[0070] In addition, anti-vibration pads 60 are provided at the corners of the bottom of the lower frame 12 to reduce the impact of vibration on the card scanner 100, thereby improving the stability of the device.

[0071] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
