Description

Technical Field

[0001] This utility model relates to the field of card reader technology, and in particular to a card transmission and reading device. Background Technology

[0002] A card reader, as a type of card reader, typically has a transmission channel. On the bottom wall of the transmission channel, two active rollers are sequentially arranged along the transmission direction to move the card. On the top wall of the transmission channel, two auxiliary rollers are correspondingly arranged, capable of moving relative to the bottom wall to cooperate with the active rollers and limit the card's contact. Simultaneously, a recognition sensor is located between the two auxiliary rollers to acquire the card's image information.

[0003] In the existing technology, two auxiliary rollers are fixedly mounted on the same plate, and two connecting rods are connected to opposite sides of the plate. The two connecting rods are located on opposite sides of the same auxiliary roller, and the plate is rotatably connected to the outer shell via four connecting rods. When the first auxiliary roller is pressed by the card, it moves upward. Since the two auxiliary rollers are fixed on the same plate, the plate rotates and moves upward as a whole, causing the second auxiliary roller to move synchronously.

[0004] Since the recognition sensor is still acquiring image information of the card when it moves to the second auxiliary roller, if the second auxiliary roller cannot move synchronously, it will hinder the movement of the card, causing the card to shake, thus affecting the quality of the image acquired by the recognition sensor.

[0005] However, in actual use, the rotation angle of the two links corresponding to the second auxiliary roller is smaller than that of the two links corresponding to the first auxiliary roller. Therefore, the upward movement distance of the second auxiliary roller is smaller than that of the first auxiliary roller. When the card moves to the second auxiliary roller, the second auxiliary roller will still obstruct the card to a certain extent, thus making it impossible to obtain accurate image information. Utility Model Content

[0006] The main purpose of this invention is to provide a card transmission and reading device that ensures that the two auxiliary rollers can move synchronously, thereby reducing obstacles encountered during card recognition and ensuring accurate image information is obtained.

[0007] To achieve the above objectives, this utility model proposes a card transmission and reading device, which includes:

[0008] A base having a transmission cavity extending along a first direction, the transmission cavity having a bottom wall and a top wall disposed opposite to each other;

[0009] Two active rollers are sequentially disposed on the bottom wall along the first direction, for driving the card to move along the first direction;

[0010] Two rotating members are disposed opposite to each other on the top wall, and both rotating members extend along the first direction and are capable of rotating towards each other. Each rotating member has a first side and a second side disposed opposite to each other along the first direction.

[0011] Two auxiliary rollers, one of which is movably connected to two of the first sides, and the other of which is movably connected to two of the second sides, and the two auxiliary rollers are respectively arranged corresponding to the two driving rollers and located between the rotation axes of the two rotating members; and

[0012] An identification component is disposed within the transmission cavity and located between the two auxiliary rollers; the identification component is used to acquire image information of the card.

[0013] One of the auxiliary rollers is pressed upwards, causing the two rotating parts to rotate in opposite directions, so that the other auxiliary roller moves upwards synchronously.

[0014] In one embodiment, each of the rotating members has a first rotating shaft extending along the first direction, the rotating member is rotatable about the extending direction of the first rotating shaft, a mounting portion is formed on both the first side and the second side, the mounting portion is located between the two first rotating shafts, and the mounting portion has a mounting hole facing the other rotating member.

[0015] Each of the auxiliary rollers includes a second shaft that is movably disposed within two opposing mounting holes, and the auxiliary roller is rotatable about the extension direction of the second shaft;

[0016] The second rotating shaft abuts against the top of the mounting hole, and there is a gap between the second rotating shaft and the bottom of the mounting hole.

[0017] In one embodiment, the distance between the second rotating shaft and the bottom wall is less than the distance between the first rotating shaft and the bottom wall.

[0018] In one embodiment, the card transmission and reading device further includes a first elastic element, the two sides of which are respectively connected to the opposite sides of the two rotating elements, and the first elastic element is used for the rotational reset of the rotating elements.

[0019] In one embodiment, the base includes a first base and a second base, which are rotatably connected. A gap is provided between the first base and the second base to form the transmission cavity. The top wall is formed on the side of the first base facing the second base, and the bottom wall is formed on the side of the second base facing the first base.

[0020] In one embodiment, the first seat includes:

[0021] The outer casing, one side of which is rotatably connected to the second base; and

[0022] A floating plate is disposed on the outer shell, and the side of the floating plate facing the second seat forms the top wall. The floating plate and the outer shell enclose an installation space. The floating plate has a first opening and two second openings communicating with the installation space. The two second openings are located on both sides of the first opening along the first direction. The identification component is disposed in the first opening. The two rotating members are rotatably disposed on the outer shell and located within the installation space. The two auxiliary rollers are located within the installation space and protrude from the top wall through the second openings.

[0023] In one embodiment, the first base further includes a plurality of second elastic members, the two sides of which are respectively connected to the outer shell and the floating plate, so that the floating plate can move relative to the outer shell.

[0024] In one embodiment, the floating plate is further provided with a plurality of mounting posts, the mounting posts being located within the mounting space, and the second elastic element being sleeved on the mounting posts.

[0025] In one embodiment, the identification component includes a first identification sensor and a second identification sensor. The first identification sensor is disposed on the top wall and located between the two auxiliary rollers, and the second identification sensor is disposed on the bottom wall and located between the two active rollers.

[0026] In one embodiment, the first identification sensor and the second identification sensor are misaligned along the first direction.

[0027] The technical solution of this utility model involves two rotating components mounted opposite each other on a top wall, capable of rotating towards each other. An auxiliary roller is movably connected to the first side of each of the two rotating components on both sides. When this auxiliary roller is pressed upwards, because it is located between the rotation axes of the two rotating components, it drives the two rotating components to rotate towards each other. The other auxiliary roller is movably connected to the second side of each of the two rotating components on both sides. As the two rotating components rotate towards each other, the other auxiliary roller moves upwards synchronously. This arrangement directly connects the two auxiliary rollers to the rotating components. When one auxiliary roller is pressed upwards, it directly drives the rotating component to rotate towards each other, thereby driving the other auxiliary roller to move upwards synchronously. This avoids synchronization problems caused by inconsistent rotation angles of the connecting rods, enabling the two auxiliary rollers to move synchronously. This reduces obstacles encountered during card recognition, thus ensuring accurate image information is obtained. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

For example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0042] A card reader, as a type of card reader, typically has a transmission channel. On the bottom wall of the transmission channel, two active rollers are sequentially arranged along the transmission direction to move the card. On the top wall of the transmission channel, two auxiliary rollers are correspondingly arranged, capable of moving relative to the bottom wall to cooperate with the active rollers and limit the card's contact. Simultaneously, a recognition sensor is located between the two auxiliary rollers to acquire the card's image information.

[0043] In the existing technology, two auxiliary rollers are fixedly mounted on the same plate, and two connecting rods are connected to opposite sides of the plate. The two connecting rods are located on opposite sides of the same auxiliary roller, and the plate is rotatably connected to the outer shell via four connecting rods. When the first auxiliary roller is pressed by the card, it moves upward. Since the two auxiliary rollers are fixed on the same plate, the plate rotates and moves upward as a whole, causing the second auxiliary roller to move synchronously.

[0044] Since the recognition sensor is still acquiring image information of the card when it moves to the second auxiliary roller, if the second auxiliary roller cannot move synchronously, it will hinder the movement of the card, causing the card to shake, thus affecting the quality of the image acquired by the recognition sensor.

[0045] However, in actual use, the rotation angle of the two links corresponding to the second auxiliary roller is smaller than that of the two links corresponding to the first auxiliary roller. Therefore, the upward movement distance of the second auxiliary roller is smaller than that of the first auxiliary roller. When the card moves to the second auxiliary roller, the second auxiliary roller will still obstruct the card to a certain extent, thus making it impossible to obtain accurate image information.

[0046] The main purpose of this invention is to provide a card transmission and reading device 100, which aims to ensure that the two auxiliary rollers 4 can move synchronously, thereby reducing the obstacles encountered during the card recognition process and ensuring the acquisition of accurate image information.

[0047] Please see Figures 1 to 7In one embodiment of this utility model, the card transmission and reading device 100 includes a base 1, two active rollers 2, two rotating members 3, two auxiliary rollers 4, and an identification component 5. The base 1 has a transmission cavity 13 extending along a first direction, and the transmission cavity 13 has a bottom wall 121 and a top wall 1121 arranged opposite to each other. The two active rollers 2 are sequentially arranged on the bottom wall 121 along the first direction for driving the card to move along the first direction. The two rotating members 3 are arranged opposite to each other on the top wall 1121, and both rotating members 3 extend along the first direction and can rotate towards each other. Each rotating member 3 has a first side 31 and a second side 32 arranged opposite to each other along the first direction. One auxiliary roller 4 is movably connected to the two first sides 31 respectively, and the other auxiliary roller 4 is movably connected to the two second sides 32 respectively. The two auxiliary rollers 4 are respectively arranged corresponding to the two active rollers 2 and are located between the rotation axes of the two rotating members 3. The identification component 5 is disposed in the transmission cavity 13 and located between the two auxiliary rollers 4. The identification component 5 is used to acquire the image information of the card. One of the auxiliary rollers 4 is pressed upwards, causing two rotating parts 3 to rotate in opposite directions, so that the other auxiliary roller 4 moves upwards synchronously.

[0048] In this embodiment, the base 1 has a transmission cavity 13, and two active rollers 2 are mounted on the bottom wall 121 to drive the card to move along a first direction. Two rotating members 3 are arranged opposite each other on the top wall 1121, extending along the first direction and capable of rotating towards each other. An auxiliary roller 4 is connected to the first side 31 and the second side 32 of each rotating member 3. An identification component 5 is installed between the two auxiliary rollers 4 to acquire image information of the card.

[0049] Understandably, by setting two rotating parts 3 opposite each other on the top wall 1121 and enabling them to rotate towards each other, and by movably connecting the two sides of an auxiliary roller 4 to the first side 31 of the two rotating parts 3 respectively, when this auxiliary roller 4 is pressed upward, it will drive the two rotating parts 3 to rotate towards each other because it is located between the rotation axes of the two rotating parts 3. Meanwhile, the two sides of the other auxiliary roller 4 are movably connected to the second side 32 of the two rotating parts 3 respectively. As the two rotating parts 3 rotate towards each other, the other auxiliary roller 4 will move upward synchronously. With this configuration, the two auxiliary rollers 4 are directly connected to the rotating parts 3. When one auxiliary roller 4 is pressed upward, it can directly drive the rotating parts 3 to rotate towards each other, thereby driving the other auxiliary roller 4 to move upward synchronously. This avoids the synchronization problem caused by the inconsistent rotation angle of the connecting rod 116, allowing the two auxiliary rollers 4 to move synchronously, reducing the obstacles encountered during card recognition, and thus ensuring the acquisition of accurate image information.

[0050] Alternatively, the identification component 5 can be a CIS (contact image sensor) for identification.

[0051] In one implementation, please refer to Figure 6 and Figure 7 Each rotating member 3 has a first rotating shaft 33 extending in a first direction. The rotating member 3 is rotatable about the extending direction of the first rotating shaft 33. A mounting portion 311 is formed on both the first side 31 and the second side 32. The mounting portion 311 is located between the two first rotating shafts 33 and has a mounting hole 312 facing the other rotating member 3. Each auxiliary roller 4 includes a second rotating shaft 41, which is movably inserted into two opposing mounting holes 312. The auxiliary roller 4 is rotatable about the extending direction of the second rotating shaft 41. The second rotating shaft 41 abuts against the top of the mounting hole 312, and there is a gap between the second rotating shaft 41 and the bottom of the mounting hole 312.

[0052] In this embodiment, each rotating component 3 is provided with a first rotating shaft 33 extending along a first direction, and the rotating component 3 can rotate around the first rotating shaft 33. The first side 31 and the second side 32 of the rotating component 3 are both provided with a mounting portion 311, which is located between the two first rotating shafts 33 and has a mounting hole 312. The auxiliary roller 4 is movably mounted in the mounting hole 312 via a second rotating shaft 41 and can rotate around the second rotating shaft 41. Simultaneously, in the initial state, i.e., when no card is inserted, the second rotating shaft 41 abuts against the top of the mounting hole 312, while a gap remains between the second rotating shaft 41 and the bottom of the mounting hole 312.

[0053] Understandably, when the two rotating parts 3 rotate towards each other, they will tilt to a certain extent. Along the extension direction of the second rotating shaft 41, the position of the rotating component on the second rotating shaft 41 will change. Therefore, the gap between the second rotating shaft 41 and the bottom of the mounting hole 312 provides space for the relative movement of the rotating component and the second rotating shaft 41. Simultaneously, the second rotating shaft 41 abuts against the top of the mounting hole 312, allowing the second rotating shaft 41 to directly drive the two rotating parts 3 to rotate towards each other when the auxiliary roller 4 is pressed upwards. Furthermore, once the two rotating parts 3 rotate, they will immediately drive the other auxiliary roller 4 to move upwards synchronously, thus ensuring the synchronicity of the movement of the two auxiliary rollers 4.

[0054] In one implementation, please refer to Figure 4 and Figure 5 The distance between the second rotating shaft 41 and the bottom wall 121 is less than the distance between the first rotating shaft 33 and the bottom wall 121.

[0055] In this embodiment, since the distance between the second rotating shaft 41 and the bottom wall 121 is less than the distance between the first rotating shaft 33 and the bottom wall 121, the auxiliary roller 4 can be brought closer to the card, thereby ensuring that the opposite sides of the card are limited and abutted by the auxiliary roller 4 and the active roller 2. If the distance between the second rotating shaft 41 and the bottom wall 121 is greater than the distance between the first rotating shaft 33 and the bottom wall 121, then the distance between the card and the auxiliary roller 4 is increased, which may cause the auxiliary roller 4 to interfere with the top wall 1121.

[0056] In one implementation, please refer to Figure 6 The card transmission and reading device 100 also includes a first elastic element 113, the two sides of which are respectively connected to the opposite side of the two rotating elements 3. The first elastic element 113 is used for the rotation reset of the rotating elements 3.

[0057] In this embodiment, the card transmission and reading device 100 further includes a first elastic element 113, which is connected to the first side 31 or the second side 32 of the two rotating elements 3. When the rotating element 3 rotates due to the pressure of the auxiliary roller 4, the first elastic element 113 deforms, providing a restoring elastic force so that the rotating element 3 returns to its initial state after the card passes through.

[0058] Preferably, in the initial state, the two rotating members 3 are in a horizontal position. Alternatively, the two rotating members 3 are slightly tilted inward and arranged in a V-shape, with the first elastic member 113 located between the two rotating members 3.

[0059] Optionally, the first elastic element 113 can be a tension spring, and a fixing hole is provided on the rotating element 3. The tension spring is connected to the two rotating elements 3 through the fixing hole.

[0060] Optionally, the first elastic element 113 includes two elements, which are connected to the first side 31 and the second side 32 of the two rotating elements 3 to enhance the elastic force of the reset.

[0061] In one implementation, please refer to Figure 1 , Figure 2 and Figure 3 The base 1 includes a first base 11 and a second base 12, which are rotatably connected. A gap is provided between the first base 11 and the second base 12 to form a transmission cavity 13. The side of the first base 11 facing the second base 12 forms a top wall 1121, and the side of the second base 12 facing the first base 11 forms a bottom wall 121.

[0062] In this embodiment, the first seat 11 and the second seat 12 are rotatably connected and enclose a transmission cavity 13. A top wall 1121 is formed on the inner side of the first seat 11, and a bottom wall 121 is formed on the inner side of the second seat 12. Understandably, this arrangement facilitates opening the transmission cavity 13 for inspection and maintenance.

[0063] Optionally, one of the first base 11 and the second base 12 is provided with a rotating shaft, and the other is provided with a rotating groove. The rotating shaft is rotatably disposed in the rotating groove, thereby allowing the two to rotate relative to each other. Optionally, the base 1 may also include a connecting rod 116. One of the first base 11 and the second base 12 is rotatably connected to one side of the connecting rod 116, and the other is provided with a sliding groove. The other side of the connecting rod 116 is movably disposed in the sliding groove and can slide along the sliding groove. It can be understood that the auxiliary connection through the connecting rod 116 enhances the stability of the first base 11 and the second base 12 during rotation.

[0064] In one implementation, please refer to Figure 4 and Figure 5 The first base 11 includes a shell 111 and a floating plate 112. One side of the shell 111 is rotatably connected to the second base 12. The floating plate 112 is disposed on the shell 111, and the side of the floating plate 112 facing the second base 12 forms a top wall 1121. The floating plate 112 and the shell 111 enclose an installation space 114. The floating plate 112 has a first opening 1122 and two second openings 1123 communicating with the installation space 114. The two second openings 1123 are located on both sides of the first opening 1122 along a first direction. The identification component 5 is disposed in the first opening 1122. Two rotating parts 3 are rotatably disposed on the shell 111 and located in the installation space 114. Two auxiliary rollers 4 are located in the installation space 114 and protrude from the top wall 1121 through the second openings 1123.

[0065] In this embodiment, the first base 11 includes a housing 111 and a floating plate 112. The housing 111 is rotatably connected to the second base 12, and the floating plate 112 is installed inside the housing 111. The side of the floating plate 112 facing the second base 12 forms a top wall 1121. An installation space 114 is formed between the floating plate 112 and the housing 111. The floating plate 112 also has a first opening 1122 and two second openings 1123. The identification component 5 is installed in the first opening 1122, the two rotating parts 3 are installed on the housing 111 and located in the installation space 114, and the two auxiliary rollers 4 protrude from the top wall 1121 through the second openings 1123.

[0066] Understandably, the floating plate 112 can act as a protective shell to prevent dust or other impurities from entering the transmission cavity 13 and adhering to the second rotating shaft 41 or the first rotating shaft 33, thereby hindering the synchronous movement of the two auxiliary rollers 4.

[0067] In one implementation, please refer to Figure 5 The first seat 11 also includes a plurality of second elastic members 115, the two sides of which are respectively connected to the outer shell 111 and the floating plate 112, so that the floating plate 112 can move relative to the outer shell 111.

[0068] In this embodiment, the first base 11 also includes a plurality of second elastic elements 115, which are connected between the outer shell 111 and the floating plate 112. When the floating plate 112 is subjected to an external force, the second elastic elements 115 can provide a buffering force, enabling the floating plate 112 to move relative to the outer shell 111, better adapting to the small fluctuations during card transmission and ensuring the stable operation of the device.

[0069] Optionally, the second elastic element 115 can be a spring, a rubber pad, or other elastic material.

[0070] In one implementation, please refer to Figure 5 The floating plate 112 is also provided with multiple mounting posts 1124, which are located within the installation space 114, and the second elastic element 115 is sleeved on the mounting post 1124.

[0071] In this embodiment, the second elastic element 115 is a spring. At the same time, the floating plate 112 is also provided with a plurality of mounting posts 1124. The spring is sleeved on the mounting posts 1124. The mounting posts 1124 can provide a certain guiding effect to ensure that the elastic element can be stably connected between the floating plate 112 and the outer shell 111.

[0072] In one implementation, please refer to Figure 3 The identification component 5 includes a first identification sensor 51 and a second identification sensor 52. The first identification sensor 51 is located on the top wall 1121 and between the two auxiliary rollers 4. The second identification sensor 52 is located on the bottom wall 121 and between the two active rollers 2.

[0073] In this embodiment, the identification component 5 includes a first identification sensor 51 and a second identification sensor 52. The first identification sensor 51 is mounted on the top wall 1121 and located between two auxiliary rollers 4; the second identification sensor 52 is mounted on the bottom wall 121 and located between two active rollers 2. Thus, by using the first identification sensor 51 and the second identification sensor 52, image information of the card can be acquired simultaneously from both the top and bottom directions, improving the comprehensiveness of image acquisition.

[0074] In one implementation, please refer to Figure 3 Along the first direction, the first identification sensor 51 and the second identification sensor 52 are misaligned.

[0075] In this embodiment, both the first identification sensor 51 and the second identification sensor 52 are CIS (Computer Integrated Sensor) devices, and they are offset along a first direction. It is understood that when the card shakes, the images acquired by both sensors may be affected. However, due to their offset arrangement, the image deviation caused by the shake can be identified by comparing the image information acquired by the two sensors. Using this deviation information, subsequent image processing algorithms can be used for shake compensation, thereby obtaining accurate image information.

[0076] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
