[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0033] In addition, the descriptions of "first", "second", etc. in the present invention are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0034] The card reader is generally equipped with an identification mechanism (such as CIS) for identifying the card image. The identification mechanism is provided with two upper and lower identification parts, such as two upper and lower CIS (contact image sensors), which are responsible for scanning the front and back of the card respectively. The card passes through the gap between the two CIS, thereby achieving the acquisition of double-sided information at one time.

[0035] The two CIS are usually fixed directly in the housing of the card reader. However, it is difficult to strictly control the gap between the two CIS during installation. They may be too close to the card channel, causing the card to jam when passing through, or too far away from the card channel, causing inaccurate focus between the card and the CIS. Or, due to collisions, long-term use of the device, the fixings may become loose, and the position of the CIS may also shift. Therefore, when the card passes through, the distance between the CIS and the card will become unstable and the distance will change, causing the focus to deviate from the preset value. Due to inaccurate focus, the captured image may appear blurred and details will be lost, which will cause a decrease in image resolution.

[0036] In view of this, the present invention provides a suction-type card reading device 100, aiming to improve the resolution of the card reading device in identifying a card image.

[0037] The specific structure of the suction card reader device 100 of the present invention is described below:

[0038] Please refer to Figures 1 to 10The present invention provides a suction card reader device 100, which includes: a housing 10, in which a card channel 111 is provided; a scanning assembly 20, which includes a first scanning component 21 and a second scanning component 22 arranged in sequence along the transmission direction of the card channel 111, wherein the first scanning component 21 is fixedly arranged in the housing 10 and partially extends into the card channel 111 from a first wall surface of the card channel 111, and the second scanning component 22 is arranged in the housing 10 and partially extends into the card channel 111 from a second wall surface of the card channel 111, and the first scanning component 21 and the second scanning component 22 are staggered along the length direction of the card channel 111; a roller assembly 30, which includes a first roller component 31 and a second roller component 32. The wheel member 32, the first roller member 31 is rotatably connected to the shell body 10 and movably arranged along the shell body 10, at least a portion of the first roller member 31 penetrates into the card channel 111 from the second wall of the card channel 111, the first roller member 31 abuts against the first scanning member 21, the second roller member 32 is rotatably connected to the shell body 10, at least a portion of the second roller member 32 penetrates into the card channel 111 from the first wall of the card channel 111, the second roller member 32 abuts against the second scanning member 22; and a supporting member 41, the supporting member 41 is elastically connected to the shell body 10, the second scanning member 22 is fixedly connected to the supporting member 41, the first roller member 31 abuts against the supporting member 41, and the supporting member 41 applies a force on the first roller member 31 to move toward the card channel 111.

[0039] Specifically, the suction card reader device 100 includes a housing 10, a scanning assembly 20, a roller assembly 30 and a carrier 41. The housing 10 is used to install and protect internal components. A card channel 111 is provided in the housing 10 for the card to pass through. The roller assembly 30 is used to drive the card to move in the card channel 111. The first wall surface and the second wall surface of the card channel 111 refer to two opposite wall surfaces of the card channel 111 along the thickness direction. The first wall surface can be a top wall or a bottom wall. Similarly, the second wall surface is a bottom wall or a top wall.

[0040] The scanning component 20 is used to identify and scan the card image. The scanning component 20 is divided into a first scanning component 21 and a second scanning component 22, which are used to scan the front and back sides of the card. The first scanning component 21 and the second scanning component 22 are both installed in the housing 10, and both partially extend into the card channel 111, so as to scan the front and back images of the card when the card passes through the card channel 111. The installation method of the first scanning component 21 can be set to screw fixing, embedded installation or welding, etc. The second scanning component 22 is elastically connected to the housing 10 through the carrier 41.

[0041] The carrier 41 is elastically connected to the housing 10 , and the connection method can be a spring 421 connection, or an elastic bracket connection. The carrier 41 applies a force to the first roller member 31 to move toward the card channel 111 , so that the first roller member 31 can be pressed against the first scanning member 21 , and the second roller member 32 is fixedly connected to the carrier 41 , so that the second scanning member 22 can be pressed against the second roller member 32 .

[0042] The first scanning component 21 and the second scanning component 22 are staggered along the length direction of the card channel 111, so that the first scanning component 21 can cooperate with the first roller component 31 and the second scanning component 22 can cooperate with the second roller component 32. By setting a carrier 41, the carrier 41 is elastically connected to the housing 10, and the second scanning component 22 is fixedly connected to the carrier 41. The carrier 41 applies a force to the first roller component 31 to move toward the card channel 111. When the card enters the card channel 111, it first passes through the first roller component 31 and the first scanning component 21. The card pushes the first roller component 31 open, and a gap is formed between the first roller component 31 and the first scanning component 21. The thickness of the gap is consistent with the thickness of the card. Under the force of the carrier 41 on the first roller component 31, the card can fit the first scanning component 21 and move; While pushing open the first roller member 31, the first roller member 31 acts on the carrier 41, so that the carrier 41 is away from the card channel 111, and then drives the second scanning member 22 away from the second roller member 32, and a gap is formed between the second scanning member 22 and the second roller member 32, and the thickness of the gap formed between the second scanning member 22 and the second roller member 32 is equal to or less than the thickness of the gap between the first roller member 31 and the first scanning member 21, so that the card can smoothly enter the second scanning member 22, and can fit the second scanning member 22 to move, ensuring that the card can smoothly and smoothly pass through the card channel 111. Under the action of the carrier 41, the card is always in contact with the first scanning member 21 and the second scanning member 22, which can well maintain the distance between the card and the scanning component 20, so that the focal length is accurate, the collected image is clearer, and the image resolution is improved.

[0043] The carrier 41 is elastically connected to the housing 10, so that the first scanning member 21 and the second scanning member 22 can automatically adjust their positions according to the thickness of the card. The first scanning member 21 and the second scanning member 22 are both provided with guiding slopes to facilitate the smooth entry and passage of the card. The structure of the carrier 41 can be a bracket or a pressure plate. When the card enters the card channel 111, the gap formed between the first roller member 31 and the first scanning member 21 just adapts to the thickness of the card, and the second scanning member 22 and the second roller member 32 maintain an appropriate distance under the action of the card. This dynamic adjustment mechanism ensures that no matter how the thickness of the card changes, it can pass through the first scanning member 21 and the second scanning member 22 in a fitting manner, maintain a stable focal length, and ensure the clarity of the image.

[0044] The staggered arrangement of the first scanning piece 21 and the second scanning piece 22 avoids the gap control problem caused by direct face-to-face installation, simplifies the installation process, reduces the gap instability problem caused by installation errors, and further improves the reliability of the equipment.

[0045] In one embodiment, the specific structure of the first roller member 31 is configured as a rotating shaft and two rollers, the rotating shaft is rotatably connected to the housing 10, and can be driven to rotate by a driving mechanism, the two rollers are fixedly connected to the rotating shaft, and partially penetrate into the card channel 111 to drive the card to move. Similarly, the specific structure of the second roller member 32 is similar to that of the first roller member 31, and will not be repeated here.

[0046] The scanning piece can be CIS, CCD (charge coupled device) or CMOS (complementary metal oxide semiconductor), etc. In this embodiment, the scanning piece is CIS, the distance between the card and CIS is 0.5mm, the scanned image is clear, and a glass plate is provided on the CIS for physical protection, the thickness of the glass plate is 0.5mm, so the card is attached to the CIS and passed, ensuring that the card passes closely against the surface of the glass plate, thereby maintaining a constant working distance, and the fixed distance keeps the focus at the best state, ensuring the clarity of the image.

[0047] The technical solution of the present invention is to arrange the first scanning member 21 and the second scanning member 22 in a staggered manner along the length direction of the card channel 111, and to set a carrier 41, the carrier 41 is elastically connected to the housing 10, and the second scanning member 22 is fixedly connected to the carrier 41, and the carrier 41 applies a force to the first roller member 31 to move toward the card channel 111, so that the first roller member 31 is in contact with the first scanning member 21, and the second roller member 32 is in contact with the second scanning member 22; when the card enters the card channel 111, the card passes through the first roller member 31, and the card pushes the first roller member 31 away, so that the first roller member 31 and the first scanning member 21 are in contact with each other. There is a gap between the first scanning piece 21 with the same thickness as the card, so that the card can be attached to the first scanning piece 21 and move. At the same time, under the action of the first roller member 31, the supporting member 41 drives the second scanning piece 22 away from the second roller member 32, so that a gap is also formed between the second scanning piece 22 and the second roller member 32 to facilitate the entry of the card. The card can be attached to the second scanning piece 22 and move. Since the card passes through the first scanning piece 21 and the second scanning piece 22, the distance between the card and the first scanning piece 21 and the second scanning piece 22 can be well maintained, a stable focal length is maintained, the collected image is clearer, and the image resolution can be improved.

[0048] In an embodiment of the present invention, the supporting member 41 includes two connecting pieces 411, and the two connecting pieces 411 are elastically connected to the two sides of the shell 10 along the width direction, and the two ends of the second scanning member 22 are respectively passed through the two connecting pieces 411, and the two ends of the second scanning member 22 are respectively connected to the two connecting pieces 411, and the two ends of the first roller member 31 are respectively supported by the two connecting pieces 411.

[0049] In detail, the carrier 41 is provided with two connecting pieces 411, such as Figure 6 The two connecting pieces 411 are fixedly connected to the two sides of the shell 10 along the width direction, and the two ends of the second scanning component 22 are fixedly connected to the two connecting pieces 411, forming a stable frame, ensuring the position accuracy of the second scanning component 22 and the first roller component 31, and ensuring that the distance between the card and the scanning component is always consistent during the scanning process.

[0050] At the same time, the two connecting pieces 411 also press against the first roller member 31 from both ends of the first roller member 31 , giving the first roller member 31 a uniform force, ensuring that it can rotate smoothly when the card passes through, and exerting appropriate pressure on the card.

[0051] In addition, a support sheet 412 may be used to connect the two connecting sheets 411, so that the connection between the two connecting sheets 411 is more stable, and the connection with the second scanning component 22 is more stable, which facilitates the card to fit through.

[0052] In the embodiment of the present invention, a first avoidance groove 4111 is formed at one end of the two connecting pieces 411 close to the first roller member 31 , and two ends of the first roller member 31 are respectively located in the two first avoidance grooves 4111 .

[0053] It is worth noting that Figure 6 A first avoidance groove 4111 is provided to cooperate with the first roller member 31, so as to limit the first roller member 31. The first roller member 31 can be pushed open, and by abutting against the groove wall of the first avoidance groove 4111, the connecting piece 411 can be moved, and the movement is more stable, ensuring that the second scanning member 22 can adapt to cards of different thicknesses while maintaining good contact with the card surface, thereby ensuring the quality and consistency of image acquisition.

[0054] At the same time, the existence of the first avoidance groove 4111 makes the installation of the first roller member 31 easier, without the need for complicated alignment or adjustment processes, thereby simplifying the assembly process and reducing assembly difficulty and time cost.

[0055] like Figure 6A support column 114 is also provided on the shell 10, a first avoidance groove 4111 is provided on one side of the connecting piece 411, and a second avoidance groove 4112 is provided on the other side of the connecting piece 411, which is used to be sleeved on the support column 114 to keep the connecting piece 411 moving stably.

[0056] In the embodiment of the present invention, the suction-type card reader device 100 further includes two elastic members 42 . The elastic members 42 are arranged in a one-to-one correspondence with the connecting piece 411 . Two ends of the elastic member 42 are respectively connected to the connecting piece 411 and the housing 10 .

[0057] Specifically, by providing the elastic member 42, continuous elastic support can be provided for the connecting piece 411, ensuring that the first roller member 31 and the second scanning member 22 can automatically adjust their positions according to the thickness of the card. When the card enters the channel, the first roller member 31 is pushed open, driving the carrier 41 (including the second scanning member 22) to move, forming an appropriate gap for the card to pass through. The presence of the elastic member 42 makes this process smoother, ensuring that no matter how the thickness of the card changes, it can pass through the scanning member in a fitting manner, maintaining the consistency of the focal length. The elastic member 42 can quickly return to its original position after the card is removed for the next use.

[0058] The elastic member 42 may be a spring 421 or an elastic airbag. Figure 6 and Fig.10 The elastic member 42 is configured as a spring 421, one end of the spring 421 is sleeved in the hole of the connecting piece 411, and the other end of the spring 421 is sleeved on the screw connected to the housing 10, so as to provide a stable elastic support and simplify the assembly process.

[0059] In the embodiment of the present invention, the elastic member 42 includes two springs 421 , which are respectively disposed at the diagonal positions of the connecting piece 411 , and two ends of the spring 421 are respectively connected to the connecting piece 411 and the housing 10 .

[0060] In detail, there are four springs 421, two springs 421 are arranged on each connecting piece 411, and two springs 421 are arranged at two opposite diagonals of the connecting piece 411, so that a uniform elastic force distribution can be formed on the connecting piece 411. The diagonally arranged springs 421 can respond more quickly to the pressure change when the card enters, so that the first roller member 31 and the second scanning member 22 can quickly adjust their positions; when the card enters the channel, the spring 421 can immediately release or apply appropriate elastic force to ensure that the first roller member 31 is pushed open while the second scanning member 22 can also move accordingly to form an appropriate gap for the card to pass through. After the card is removed, the spring 421 can quickly reset to prepare for the next scan. No matter how the thickness of the card changes, the spring 421 can ensure that the scanning member is always close to the card surface, maintain the best focal length, and ensure the clarity and resolution of the image.

[0061] like Fig.10 , showing that a spring 421 is arranged at one of the diagonals of the connecting piece 411, one end of the spring 421 is connected through a hole on the connecting piece 411, and the other spring 421 is not shown. At the same time, it can be seen that two holes for connecting the two springs 421 are arranged on the connecting piece 411.

[0062] Furthermore, the elastic constant of the spring 421 is set to 0.1-0.2 N / mm. Excessive pressure on the card is avoided, and when the card enters the channel, the first roller member 31 can be easily pushed open to ensure that the card can pass smoothly. At the same time, the spring 421 can provide appropriate elastic force, so that the first roller member 31 and the second scanning member 22 automatically adjust their positions according to the thickness of the card, forming a suitable gap for the card to pass through, maintaining the consistency of focal length and image quality.

[0063] In an embodiment of the present invention, the roller assembly 30 also includes a third roller member 33 and a fourth roller member 34. The third roller member 33 and the fourth roller member 34 are both rotatably mounted on the shell 10, and penetrate into the card channel 111 along the first wall and the second wall of the card channel 111 respectively. The third roller member 33 and the fourth roller member 34 are arranged opposite to each other, and the second roller member 32 and the third roller member 33 are arranged in sequence along the transmission direction of the card channel 111.

[0064] It is worth noting that the specific structures of the third roller member 33 and the fourth roller member 34 are similar to those of the first roller member 31 , and will not be described in detail herein.

[0065] like Figure 4By setting the third roller member 33 and the fourth roller member 34, when the card enters the second scanning member 22 from the first scanning member 21 and gradually moves, the third roller member 33 and the fourth roller member 34 first clamp the head of the card. At this time, the forward driving force provided by the third and fourth roller members 34 is much greater than the resistance when the card is separated from the second scanning member 22 and the second roller member 32. The third roller member 33 and the fourth roller member 34 intervene in advance to provide additional power to ensure that the card will not slow down or stop due to friction or other resistance when it is separated from the second scanning member 22. This design allows the card to maintain a stable forward speed throughout the entire transmission process, avoiding speed fluctuations caused by resistance. By clamping the head of the card in advance, the third roller member 33 and the fourth roller member 34 effectively take over the movement inertia of the card and prevent the speed change phenomenon that may occur when the tail of the card is separated.

[0066] When the card is about to leave the second scanning member 22 and the second roller member 32, the third roller member 33 and the fourth roller member 34 have already clamped the head of the card, and can also offset the impact force when the card leaves the previous set of wheels. The entire card transmission process is smoother, reducing the risk of jamming or blocking, and improving the efficiency of card passing.

[0067] Because the card moves more smoothly and stably, it always maintains the optimal distance from the scanned object during the transmission process, ensuring the consistency of focal length and avoiding image blur or distortion caused by distance changes. By reducing impact force and resistance, the jitter of the card in the scanning area is greatly reduced, further improving the clarity and detail of the image and improving the resolution of image acquisition.

[0068] In an embodiment of the present invention, the suction-type card reading device 100 also includes a first guide rail 51 and a second guide rail 52, wherein the first guide rail 51 is fixedly connected to the shell 10, and the second guide rail 52 is elastically connected to the shell 10, and the first guide rail 51 and the second guide rail 52 are both located at the entrance of the card channel 111, and are respectively arranged on both sides of the card channel 111 along the width direction.

[0069] Specifically, the first guide rail 51 and the second guide rail 52 are located at the entrance of the card channel 111, and can correct the card when it enters, ensuring that the card enters the channel at the correct angle and position. The elastic connection of the second guide rail 52 allows it to be fine-tuned according to the specific position of the card, ensuring that the card can smoothly enter the channel without obstruction. The second guide rail 52 can be connected to the housing 10 by a spring.

[0070] Through the deflection correction mechanism, the card is already in the correct position when entering the channel, reducing the risk of deviation during subsequent transmission; the card is aligned when entering, ensuring that it always maintains a stable path during the entire transmission process, avoiding scanning errors or card blockages caused by deviation; the card after deflection is more stable during transmission, reducing unnecessary jitter, reducing the impact of external factors (such as vibration, friction, etc.) on image acquisition, and improving the quality of image acquisition.

[0071] The elastically connected second guide rail 52 can be fine-tuned according to the specific position of the card to accommodate cards of different widths, thereby enhancing the versatility and adaptability of the device.

[0072] At the entrance of the card channel 111, guide expansion openings are provided on the first guide rail 51 and the second guide rail 52. Figure 6 Users can insert the card without special alignment, and the card will be automatically corrected, which simplifies the operation steps and improves the user experience.

[0073] In one embodiment, the distance between the first guide rail 51 and the second guide rail 52 can be set to be smaller than the width of the card. The elastically connected second guide rail 52 can well limit the position of the card so that the card enters the first scanning part 21 at the correct position.

[0074] In an embodiment of the present invention, the housing 10 includes a mounting shell 11 and a rotating shell 12, the mounting shell 11 is provided with the card passage 111, the first scanning component 21 and the second scanning component 22 are both arranged in the mounting shell 11, the first roller component 31 and the second roller component 32 are both arranged in the mounting shell 11, the top wall of the mounting shell 11 close to the entrance of the card passage 111 is provided with an opening 112, and the rotating shell 12 is rotatably connected to the mounting shell 11; the suction-type card reader device 100 also includes an active roller component 60 and a driven roller component 70, the active roller component 60 is rotatably mounted on the mounting shell 11, and at least a portion of the active roller component 60 penetrates into the card passage 111 from the first wall surface of the card passage 111. The driven roller member 70 is rotatably mounted on the rotating shell 12, and at least a portion of the driven roller member 70 penetrates into the card channel 111 from the second wall of the card channel 111. The active roller member 60 is arranged opposite to the driven roller member 70, and the active roller member 60 and the first roller member 31 are arranged in sequence along the transmission direction of the card channel 111; the rotating shell 12 has a covered state and an open state; in the covered state, the rotating shell 12 covers the opening 112, and at least a portion of the driven roller member 70 penetrates into the card channel 111 from the top wall of the card channel 111; in the open state, the rotating shell 12 is away from the opening 112, and the active roller member 60 is exposed to the opening 112.

[0075] Specifically, the active roller member 60 and the driven roller member 70 are located in the entrance area of ​​the card channel 111. In the open state, the rotating shell 12 is away from the opening 112, and the active roller member 60 is exposed to the outside, so that the user can directly access the inside of the card channel 111, which is convenient for removing the stuck card or performing necessary repairs. When the card is stuck or needs to be repaired, the operation can be easily performed by simply opening the rotating shell 12. Since the first scanning component 21 and the second scanning component 22 are both arranged in the mounting shell 11, the opening of the rotating shell 12 will not affect these components, ensuring the safety and stability of the device. The user does not need to disassemble the entire device or use complex tools, but can simply open the rotating shell 12 to solve the problem, greatly shortening the troubleshooting time. The active roller member 60 and the driven roller member 70 are arranged relative to each other, providing uniform traction and ensuring the smooth transmission of the card in the channel.

[0076] In one embodiment, if Figure 3 A buckle 121 is provided on the rotating shell 12, and a slot 113 is opened on the inner wall of the mounting shell 11. The buckle 121 and the slot 113 are closely matched to ensure that the rotating shell 12 is firmly fixed in the closed state to prevent accidental loosening.

[0077] In another embodiment, if Figure 4 The active roller member 60 includes a fifth roller member 61 and a sixth roller member 62, and the driven roller member includes a seventh roller member 71 and an eighth roller member 72. The fifth roller member 61 is arranged opposite to the seventh roller member 71, and the sixth roller member 62 is arranged opposite to the eighth roller member 72. The fifth roller member 61, the sixth roller member 62, the first roller member 31, the second roller member 32 and the third roller member 33 are arranged in sequence along the transmission direction of the card channel 111. When the card enters between the sixth roller member 62 and the eighth roller member 72 from between the fifth roller member 61 and the seventh roller member 71 and gradually moves, the first roller member 31 and the first scanning member 21 clamp the card head in advance, providing a forward driving force far greater than the disengagement resistance, which ensures that the card will not be decelerated or stopped due to friction or other resistance when it is disengaged from the sixth roller member 62 and the eighth roller member 72, and maintains a stable forward speed to avoid speed fluctuations. The card maintains a stable speed during the entire transmission process, reducing the risk of jamming or blocking and improving the passing efficiency. At the same time, the first roller member 31 and the first scanning member 21 bear the movement inertia of the card, offsetting the impact force when the card is separated from the previous set of wheels, making the transmission smoother.

[0078] Therefore, the suction-type card reader device 100 sequentially arranges each group of rollers along the transmission direction of the card channel 111. Through this design, when the card moves and switches to the next group of rollers, the head of the card will be clamped in advance by the next group of rollers, and the tail of the card will be released. The card moves more smoothly and stably, which significantly improves the quality of image acquisition and the overall performance of the device.

[0079] In an embodiment of the present invention, the suction-type card reader device 100 further includes a driving assembly 80, which includes a motor 81, a transmission gear set 82 and a transmission plate 83. The motor 81 is installed on the housing 10, one end of the transmission gear set 82 is connected to the motor 81, and the other end of the transmission gear set 82 is respectively connected to the first roller member 31 and the second roller member 32 for transmission, the transmission plate 83 is fixedly connected between the first roller member 31 and the second roller member 32, and the transmission plate 83 is abutted against the supporting member 41.

[0080] In detail, the power source is provided by the motor 81, and the accuracy and synchronization of power transmission are ensured by the transmission gear set 82; the motor 81 efficiently transmits power to the first roller member 31 and the second roller member 32 through the transmission gear set 82, ensuring the stability and synchronization of card transmission.

[0081] In addition, in one embodiment, the transmission gear set 82 is also connected to the sixth roller member 62 through a belt, and the sixth roller member 62 is connected to the fifth roller member 61 through a belt transmission. Therefore, each group of roller members can be driven to rotate by a motor 81 to drive the card to move in the card channel 111.

[0082] The transmission sheet 83 is used to maintain the distance between the first roller member 31 and the second roller member 32, ensuring the stability of the spacing therebetween, avoiding the spacing change caused by mechanical vibration or external factors, and improving the accuracy of card transmission.

[0083] In another embodiment, if Figure 8 The side of the transmission piece 83 is provided with a protruding column 831, which is held in the first avoidance groove 4111 of the carrier 41. When the card enters the channel and lifts the first roller member 31, the transmission piece 83 moves accordingly, and the protruding column 831 thereon slides along the first avoidance groove 4111 of the carrier 41. The movement of the protruding column 831 is transmitted to the second roller member 32 through the connecting piece 411, so that it moves accordingly, ensuring that the card can pass through the scanning area smoothly. The cooperation between the protruding column 831 of the transmission piece 83 and the first avoidance groove 4111 ensures the stability of the card during the entire transmission process.

[0084] In an embodiment of the present invention, the suction-type card reader device 100 further includes an optical recognition module 91, which is installed in the shell 10 and at least partially located in the card channel 111; and / or, the suction-type card reader device 100 further includes a magnetic card reading and writing module 92, which is installed in the shell 10 and partially extends into the card channel 111; and / or, the suction-type card reader device 100 further includes a contactless recognition module 93, which is installed in the shell 10 and located outside the card channel 111.

[0085] Specifically, Figure 3 and Fig. 9 The optical recognition module 91 , the magnetic card reading and writing module 92 and the contactless recognition module 93 are all located at the entrance area of ​​the card channel 111 to avoid affecting the scanning component 20 .

[0086] The optical recognition module 91 can quickly identify and read the information on the card. The optical recognition module 91 has white light, red light, purple light, etc., which can improve the accuracy of recognition. The magnetic card reading and writing module 92 is set to read and write the magnetic information on the magnetic card. The side opposite to the magnetic card reading and writing module 92 is provided with an auxiliary wheel 35 to cooperate with the card to move. The contactless recognition module 93 is set to quickly and efficiently identify the information on the card wirelessly without physical contact. It can immediately identify the information on the card when the card approaches the device, such as RFID tags, NFC chips, etc.

[0087] The suction-type card reader device 100 increases the function of identifying multiple types of cards by providing multiple modules.
