Description

Technical Field

[0001] This invention relates to the field of document scanning technology, and more particularly to a document scanning device for a financial payment terminal. Background Technology

[0002] In order to view, archive, and back up documents, documents are usually scanned to generate electronic files, which facilitates viewing, archiving, and backup.

[0003] CN220043492U discloses a document scanning device for a financial payment terminal, comprising a cabinet, lifting guide rails, a lifting motor, a document box, a rotary motor, a bracket, and a high-speed scanner module. A loading slot is located at the center of the right side of the front end of the cabinet. A rack is vertically mounted on the left side of the cabinet base below the loading slot. A pair of lifting guide rails are mounted on both sides of the rack, and a mounting plate is positioned between the pair of lifting guide rails. A slider is positioned between the mounting plate and the pair of lifting guide rails. A lifting motor is mounted at the lower end of the mounting plate, and the end of the motor's drive shaft passes through the mounting plate and has a gear that meshes with the rack. A document box is mounted at the upper end of the mounting plate. A rotary motor is mounted on the right side of the cabinet below the loading slot. An L-shaped bracket is mounted above the rotary motor. The lower end of the vertical plate of the L-shaped bracket is connected to the drive shaft of the rotary motor via a rotating flange. The rotary motor drives the bracket to rotate through the rotating flange. A high-speed scanner module is mounted at the front end of the horizontal plate of the bracket, with the scanner's camera end facing downwards. After the operator places the documents into the document box through the drop-in compartment, the rotary motor drives the bracket to rotate towards the document box. When the high-speed scanner module moves to the upper center of the document box, it stops rotating. The high-speed scanner module takes a picture of the document and transmits the data to the control console. After taking the picture, the rotary motor drives the bracket to return to the initial position. The turnover mechanism inside the cabinet transfers the photographed documents to the conveyor mechanism. The above steps are repeated until all the documents in the document box have been photographed.

[0004] When the aforementioned document scanning device scans documents, if multiple documents are placed in the document box, it can only scan the front of the top document. During scanning, only one document can be scanned at a time, requiring manual placement of each document into the document box, which affects the scanning speed. Summary of the Invention

[0005] In view of this, it is necessary to provide a document scanning device for a financial payment terminal to solve the technical problem that existing document scanning devices require manual placement of documents one by one for scanning.

[0006] To achieve the above-mentioned technical objectives, the present invention provides a document scanning device for a financial acquiring machine, comprising:

[0008] A first scanning mechanism is disposed above the loading area and is used to scan the documents in the loading area;

[0009] A second scanning mechanism is disposed below the transparent area and is used to scan the documents in the transparent area;

[0010] A moving mechanism has a fixed end and a moving end. The fixed end of the moving mechanism is connected to the support platform, and the moving end of the moving mechanism is capable of moving in a plane parallel to the support platform and in a direction perpendicular to the support platform.

[0011] An adsorption mechanism is connected to the mobile end. The adsorption mechanism has multiple adsorption holes for adsorbing documents. The adsorption mechanism is used to move documents between the feeding area, the viewing area, and the storage area.

[0012] In one embodiment, the adsorption mechanism includes an adsorption plate, an air extraction component, and a control component. The adsorption plate has a plurality of adsorption holes on one side and a flow channel on the other side, the flow channel being connected to each of the adsorption holes. The air inlet of the air extraction component is connected to the flow channel. The control component is disposed on the communication path between the flow channel and the air extraction component, and the control component is used to control the opening and closing of the communication path.

[0014] The control component includes a rotating sleeve, an elastic part, an elastic strip, and a first slider. The rotating sleeve is rotatably connected to the adsorption plate. The elastic part is connected to the rotating sleeve and the adsorption plate and is used to provide the elastic force for the rotating sleeve to return to its original position after rotation. One end of the elastic strip is connected to the rotating sleeve and is wound around the rotating sleeve. The first slider is slidably disposed in the flow channel and connected to the other end of the elastic strip.

[0015] When the first slider slides, it can drive the elastic strip to slide along the guide of the flow channel, and the sliding elastic strip can cover or avoid the connecting hole.

[0016] In one embodiment, the control component further includes a rotating shaft, a connecting rod, a second slider, and a driving unit. The rotating shaft is rotatably connected to the adsorption plate and is arranged along the axial direction of the vortex. The connecting rod is arranged radially along the rotating shaft. The second slider is slidably sleeved on the connecting rod. The driving unit is connected to the rotating shaft and the adsorption plate and is used to drive the rotating shaft to rotate so that the first slider can slide along the guide of the flow channel through the connecting rod and the second slider.

[0017] In one embodiment, the connection between the connecting hole and the flow channel is located on the side wall near the center of the two opposite side walls of the flow channel, and the elastic strip is slidably attached to the side wall near the center of the two opposite side walls of the flow channel.

[0018] In one embodiment, the adsorption mechanism further includes a guide bracket connected to the adsorption plate, the guide bracket having an annular guide groove coaxial with the rotating shaft, and the end of the connecting rod away from the rotating shaft being slidably disposed in the annular guide groove.

[0019] In one embodiment, the adsorption mechanism further includes a cover that covers the other side of the adsorption plate and encloses the control component and the guide bracket.

The second support plate connects the two first support plates. When multiple storage components are stacked sequentially along the height direction, the two first support plates abut against the second support plate of the adjacent storage component.

[0023] In one embodiment, a limiting groove is formed at the bottom of the first support plate, and a limiting block is formed at the top of the second support plate relative to the limiting groove. When multiple storage components are stacked sequentially along the height direction, the limiting block is inserted into the limiting groove of the adjacent storage component.

[0077] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0078] like Figures 1 to 16 As shown, the present invention provides a document scanning device for a financial payment terminal, including a support mechanism 1, a first scanning mechanism 2, a second scanning mechanism 3, a moving mechanism 4, and an adsorption mechanism 5. The support mechanism 1 includes a support platform 11, which has a loading area 11a, a viewing area 11b, and a storage area 11c. The first scanning mechanism 2 is disposed above the loading area 11a and is used to scan the documents in the loading area 11a. The second scanning mechanism 3 is disposed below the viewing area 11b and is used to scan the documents in the viewing area 11b. The moving mechanism 4 has a fixed end and a moving end. The fixed end of the moving mechanism 4 is connected to the support platform 11, and the moving end of the moving mechanism 4 can move along a plane parallel to the support platform 11 and can move in a direction perpendicular to the support platform 11. The adsorption mechanism 5 is connected to the moving end and has multiple adsorption holes 51a for adsorbing documents. The adsorption mechanism 5 is used to move the documents between the loading area 11a, the viewing area 11b, and the storage area 11c.

[0079] Specifically, the document to be scanned is placed in the loading area 11a; the first scanning mechanism 2 is activated to scan the document at the top of the loading area 11a, scanning the front information of the document; the moving end of the moving mechanism 4 moves along a plane parallel to the support platform 11, causing the adsorption mechanism 5 to move above the loading area 11a; the adsorption mechanism 5 is activated, adsorbing the topmost document through the adsorption hole 51a; the moving end of the moving mechanism 4 moves upward along a direction perpendicular to the support platform 11, lifting the document from the loading area 11a; the moving end of the moving mechanism 4 moves again along a plane parallel to the support platform 11, moving the document above the viewing area 11b; the adsorption mechanism 5 moves downward along a direction perpendicular to the support platform 11, placing the document in the viewing area 11b; the second scanning mechanism 3 is activated to scan the document in the viewing area 11b. At this point, the reverse side of the document is scanned; after scanning is completed, the adsorption mechanism 5 is activated again to lift the document from the viewing area 11b; the moving end of the moving mechanism 4 moves the document above the storage area 11c and stores the document in the storage area 11c; repeat the above steps until all documents are scanned.

[0080] By setting up two scanning mechanisms to scan the front and back of the document respectively, the scanning efficiency is improved, and there is no need to manually flip the document to scan the front and back. The combined use of the moving mechanism 4 and the adsorption mechanism 5 realizes the automatic transfer of documents between different areas, reduces the degree of manual intervention, and improves work efficiency. The adsorption mechanism 5 can adsorb single documents, which is suitable for various financial collection scenarios and helps to improve the automation level of financial management.

[0081] It should be understood that the first scanning mechanism 2 and the second scanning mechanism 3 can be CMOS (Complementary Metal Oxide Semiconductor) scanners. CMOS scanners are image sensors based on CMOS technology. They perform raster scanning on the pixel array through row and column scanners to convert light signals into digital signals. The first scanning mechanism 2 and the second scanning mechanism 3 can also be other devices capable of scanning documents.

[0082] It should be understood that the moving mechanism 4 can be a cantilevered three-coordinate moving mechanism 4, a gantry-type three-coordinate moving mechanism 4, etc. In one embodiment, the moving mechanism 4 is a three-axis moving structure with X, Y, and Z axes, wherein the X and Y directions are parallel to the plane where the support platform 11 is located, and the Z direction is perpendicular to the support platform 11.

[0083] It should be understood that the adsorption mechanism 5 can be a vacuum adsorption structure or a gas adsorption structure.

[0084] It should be understood that in order to achieve the perspective of the perspective area 11b of the support platform 11, the perspective area 11b of the support platform 11 can be set as a hollow structure, or light-transmitting glass can be set in the perspective area 11b of the support platform 11, or the entire support platform 11 can be made of light-transmitting glass material.

[0085] It should be understood that the loading area 11a and the storage area 11c are both positions that are artificially divided on the support platform 11. The loading area 11a and the storage area 11c can be located on opposite sides of the viewing area 11b, or they can be set on the same side of the viewing area 11b.

[0086] It should be understood that the first scanning mechanism 2 and the second scanning mechanism 3 can be respectively set above or below the support platform 11 by brackets, or the scanning components can be respectively set above or below the support platform 11 by their own support structure.

[0087] In one embodiment, the adsorption mechanism 5 includes an adsorption plate 51, an air extraction component 52, and a control component 53. The adsorption plate 51 has a plurality of adsorption holes 51a on one side and a flow channel 51b on the other side, and the flow channel 51b is connected to each adsorption hole 51a. The air inlet end of the air extraction component 52 is connected to the flow channel 51b. The control component 53 is disposed on the communication path between the flow channel 51b and the air extraction component 52, and the control component 53 is used to control the opening and closing of the communication path.

[0088] Specifically, when it is necessary to absorb the document, the control component 53 opens, making the connection path between the flow channel 51b and the air extraction component 52 unobstructed; the air extraction component 52 starts, drawing air from the flow channel 51b through the air inlet, creating a negative pressure inside the flow channel 51b; since the flow channel 51b is connected to each adsorption hole 51a, the negative pressure causes the adsorption hole 51a to generate suction, thereby adsorbing the document; when it is necessary to release the document, the control component 53 closes, cutting off the connection path between the flow channel 51b and the air extraction component 52. At this time, the suction in the adsorption hole 51a disappears, and the document can be easily removed.

[0089] It should be understood that the extraction component 52 can be a vacuum pump, a centrifugal fan, or a diaphragm pump, etc.

[0090] It should be understood that the control component 53 can be a solenoid valve, a pneumatic valve, or a hydraulic valve, etc.

[0091] It should be understood that the document can also be released from the adsorption plate 51 by closing the control element 53 when the document needs to be released, and then connecting the air outlet of the air extraction element 52 to the flow channel 51b, so that the airflow pushes the document away from the adsorption plate 51.

[0092] Since the sizes of documents may vary, if the adsorption area of ​​the adsorption plate 51 corresponds to the largest document, then when the adsorption plate 51 adsorbs a smaller document, it will also adsorb documents below the smaller document. If the adsorption area of ​​the adsorption plate 51 corresponds to the smallest document, then when the adsorption plate 51 adsorbs a relatively large document, the edges of the document will bend downwards, causing the document to collide with other components on the support platform 11 during movement, resulting in the document being bent or folded. Therefore, in one embodiment, multiple adsorption holes 51a are arranged in a vortex pattern on one side of the adsorption plate 51; the flow channel 51b is vortex-shaped; the adsorption plate 51 also has multiple connecting holes 51c, which are connected to the adsorption holes 51a. The control component 53 includes a rotating sleeve 531, an elastic part 532, an elastic strip 533, and a first slider 534. The rotating sleeve 531 is rotatably connected to the adsorption plate 51. The elastic part 532 is connected to the rotating sleeve 531 and the adsorption plate 51, and is used to provide the elastic force for the rotating sleeve 531 to return to its original position after rotation. One end of the elastic strip 533 is connected to the rotating sleeve 531 and is wound around the rotating sleeve 531. The first slider 534 is slidably disposed in the flow channel 51b and is connected to the other end of the elastic strip 533. When the first slider 534 slides, it can drive the elastic strip 533 to slide along the guide of the flow channel 51b, and the sliding elastic strip 533 can cover or avoid the connecting hole 51c.

[0093] Specifically, when adsorbing documents, the air extraction component 52 is activated, drawing air from the flow channel 51b through the air inlet, creating a negative pressure within the flow channel 51b. The flow channel 51b connects to the adsorption holes 51a through the connecting hole 51c. At this time, the adsorption holes 51a connected to the flow channel 51b through the connecting hole 51c form a negative pressure suction force. The adsorption holes 51a with suction force can adsorb documents. In order to enable the adsorption holes 51a to adsorb documents of different sizes, in this embodiment, a number of adsorption holes 51a corresponding to the document size can be selectively opened. The selective opening method is to slide the first slider 534, which slides along the vortex-shaped flow channel 51b. When the first slider 534 slides, it drives the elastic strip 533 to move. When the first slider 534 moves away from the rotating sleeve 531, the first slider 534 drives the elastic strip 533 to move. The elastic strip 533 is gradually released from the rotating sleeve 531 and gradually unfolds along the flow channel 51b. During the unfolding process, the elastic strip 533 gradually blocks the connecting holes 51c in the flow channel 51b. By blocking the connecting holes 51c, part of the flow channel 51b is closed. The longer the elastic strip 533 unfolds, the more connecting holes 51c can be closed, and the fewer adsorption holes 51a can form negative pressure suction. The size of the documents that the adsorption plate 51 can adsorb is reduced.

[0094] When the elastic strip 533 unfolds, it drives the rotating sleeve 531 to rotate. The rotating sleeve 531 twists the elastic part 532, and the elastic part 532 accumulates elastic restoring force. When the first slider 534 slides in the direction close to the rotating sleeve 531, the elastic part 532 releases the elastic restoring force, causing the rotating sleeve 531 to wrap around the elastic strip 533. The number of connecting holes 51c blocked by the elastic strip 533 decreases, the number of adsorption holes 51a closed by the elastic strip 533 decreases, and the size of the adsorption holes 51a that can form negative pressure suction increases. At this time, the size of the documents that the adsorption plate 51 can adsorb increases.

[0095] It should be understood that the first slider 534 can be driven manually or by an electric or actuated structure to slide along the flow channel 51b.

[0096] It should be understood that the rotating sleeve 531 can be rotatably connected to the adsorption plate 51 by means of a pivot pin and a pivot column, etc. In one embodiment, the rotating sleeve 531 is rotatably embedded in the flow channel 51b by means of a pivot shaft.

[0097] It should be understood that the rotating sleeve 531 can be a rotating drum or a rotating winding roller.

[0098] It should be understood that the elastic part 532 can be a torsion spring, an elastic block, etc.

[0099] It should be understood that the elastic strip 533 can be made of materials such as rubber, silicone, and latex.

[0100] It should be understood that the rotating sleeve 531 can be rotatably positioned at the center of the vortex or at the end of the vortex.

[0101] In order to drive the first slider 534 to move in a vortex shape along the flow channel 51b, in one embodiment, the control member 53 further includes a rotating shaft 535, a connecting rod 536, a second slider 537, and a driving part 538. The rotating shaft 535 is rotatably connected to the adsorption plate 51 and is arranged along the axial direction of the vortex. The connecting rod 536 is arranged radially along the rotating shaft 535. The second slider 537 is slidably sleeved on the connecting rod 536. The driving part 538 is connected to the rotating shaft 535 and the adsorption plate 51 and is used to drive the rotating shaft 535 to rotate so as to drive the first slider 534 to slide along the guide of the flow channel 51b through the connecting rod 536 and the second slider 537.

[0102] Specifically, when the first slider 534 needs to slide, the drive unit 538 is activated, driving the rotating shaft 535 to rotate. The rotating shaft 535 transmits the rotational motion to the second slider 537 through the connecting rod 536. Since the second slider 537 is connected to the first slider 534 and is slidably sleeved on the connecting rod 536, the second slider 537 will move radially along the connecting rod 536. During the movement, the second slider 537 will drive the first slider 534 to slide along the guide of the flow channel 51b. Since the flow channel 51b is vortex-shaped, the sliding trajectory of the first slider 534 will also be vortex-shaped. When the first slider 534 slides, it will drive the elastic strip 533 to slide along the guide of the flow channel 51b. Through the sliding of the first slider 534, the elastic strip 533 is driven to slide. The number of adsorption holes 51a with adsorption force is adjusted by the sliding elastic strip 533.

[0103] By cooperating with the first slider 534 through the rotating shaft 535, connecting rod 536, second slider 537 and driving part 538, the first slider 534 can be controlled to slide to any position in the flow channel 51b. The sliding of the first slider 534 along the flow channel 51b can be controlled without manual intervention, making it easy to achieve automated control.

[0104] It should be understood that the drive unit 538 can be a direct drive motor, a combination of a motor and a gear transmission mechanism, a combination of a motor and a belt transmission mechanism, or a hydraulic motor, etc.

[0105] When the connecting hole 51c is located on the bottom inner wall of the flow channel 51b, the elastic strip 533 blocks the connecting hole 51c located at the bottom of the flow channel 51b. When the suction device 52 is activated, the negative pressure adsorption formed by the suction device 52 in the flow channel 51b can pull the elastic strip 533 to move away from the bottom of the flow channel 51b, which may cause some adsorption holes 51a to form negative pressure suction uncontrollably. In one embodiment, the connection between the connecting hole 51c and the flow channel 51b is located on the side wall near the center of the two opposite side walls of the flow channel 51b, and the elastic strip 533 can slide and fit against the side wall near the center of the two opposite side walls of the flow channel 51b.

[0106] In this application, the connection between the connecting hole 51c and the flow channel 51b is located on the side wall near the center of the two opposite side walls of the flow channel 51b. The elastic strip 533 slides around the vortex-shaped side wall of the flow channel 51b. When the elastic strip 533 slides around the side wall, it is stretched to achieve tight contact between the strip and the side wall. At this time, the suction device 52 is activated. When the suction device 52 forms a negative pressure suction force in the flow channel 51b, the negative pressure suction force is transmitted outward through the adsorption hole 51a. Since there is an angle between the adsorption direction of the adsorption hole 51a and the blocking direction of the elastic strip 533, the suction force that drives the elastic strip 533 to detach from the side wall can be reduced. Moreover, when the elastic strip 533 is driven by the first slider 534 to adhere to the vortex-shaped side wall of the slide groove, the elastic strip 533 can adhere tightly to the vortex-shaped side wall of the slide groove, preventing the negative pressure suction force from driving the elastic strip 533 to detach from the side wall of the slide groove.

[0107] In one embodiment, the adsorption mechanism 5 further includes a guide bracket 54, which is connected to the adsorption plate 51. The guide bracket 54 has an annular guide groove 54a, which is coaxial with the rotating shaft 535. The end of the connecting rod 536 away from the rotating shaft 535 is slidably disposed in the annular guide groove 54a.

[0108] When the drive unit 538 drives the rotating shaft 535 to rotate, the drive unit 538 drives one end of the connecting rod 536 to slide through the rotating shaft 535. The other end of the connecting rod 536 slides in the annular groove of the guide bracket 54, providing a stable sliding path for the connecting rod 536. In this embodiment, the adsorption mechanism 5 introduces the guide bracket 54. Through the cooperation between the annular guide groove 54a and the connecting rod 536, the stability and accuracy of the first slider 534 sliding along the vortex channel 51b are further improved.

[0109] In one embodiment, the adsorption mechanism 5 further includes a cover 55, which covers the other side of the adsorption plate 51 and covers the control component 53 and the guide bracket 54 inside; the air inlet of the air extraction component 52 is connected to the cover 55 and is connected to the flow channel 51b through the cover 55.

[0110] The cover 55 is placed on the other side of the adsorption plate 51, hiding the internal structure such as the control component 53 and the guide bracket 54, and preventing external environmental factors such as dust and moisture from damaging the internal structure. The air inlet of the air extraction component 52 is connected to the cover 55, so that a negative pressure is formed inside the cover 55. The cover 55 is connected to the flow channel 51b, and then the flow channel 51b generates suction through the adsorption holes 51a on the adsorption plate 51.

[0111] It should be understood that the flow channel 51b can be a structure embedded inside the adsorption plate 51, or it can be formed by opening inward on the other side of the adsorption plate 51. In this embodiment, the flow channel 51b is formed by opening inward on the other side of the adsorption plate 51. By providing a cover 55, the cover 55 can seal the opening side of the flow channel 51b. When a negative pressure suction is formed inside the cover 55, the negative pressure suction can act on the document on the other side of the adsorption plate 51 through the flow channel 51b, the connecting hole 51c, and the adsorption hole 51a.

[0112] It should be understood that the drive unit 538 can be directly fixed to the adsorption plate 51. In one embodiment, the drive unit 538 is fixed to the cover 55 and connected to the adsorption plate 51 through the cover 55.

[0113] Since the documents are made of paper and are not necessarily flat, if the documents are stacked too high when they are placed on the loading station, there is a risk of them collapsing. Moreover, if the documents are stacked too high, the documents at the top will be tilted, which will affect the scanning effect. However, if the documents are stacked too low, the documents will need to be added frequently. Therefore, in one embodiment, the support mechanism 1 also includes multiple storage components 12, which are stacked sequentially along the height direction, and adjacent storage components 12 along the height direction form a storage space for accommodating documents.

[0114] By setting up multiple storage components 12 and the storage space between the multiple storage components 12 to accommodate documents, the documents are separated in the vertical direction. The storage components 12 can provide support for the documents in each storage space, preventing the documents from collapsing due to stacking aisles, preventing the documents from tilting due to excessive stacking, and the multiple storage spaces can accommodate a large number of documents, making the stacked documents more stable.

[0115] After the storage component 12 is set up, when the adsorption mechanism 5 adsorbs the documents, it first adsorbs the storage component 12 to the storage area 11c, and then adsorbs the documents located on the loading position. When the documents in a certain storage space are adsorbed, the storage component 12 is adsorbed to the storage area 11c again, and then the documents in the next storage space are scanned and adsorbed. After the documents are scanned in the viewing area 11b, they are moved to the storage component 12 in the storage area 11c under the joint action of the adsorption mechanism 5 and the moving mechanism 4, so as to realize the storage of the scanned documents.

[0116] It should be understood that the storage component 12 can be a block, and a receiving groove is formed on the side of the storage component 12 facing downward, forming a receiving space between the receiving groove and the storage component 12 below.

[0117] In one embodiment, the storage component 12 includes two first support plates 121 and a second support plate 122. The two first support plates 121 are parallel to each other and spaced apart. The second support plate 122 connects the two first support plates 121. When multiple storage components 12 are stacked sequentially along the height direction, the two first support plates 121 abut against the second support plate 122 in the adjacent storage component 12.

[0118] Specifically, when multiple storage components 12 are stacked sequentially along the height direction, the two first support plates 121 in each storage component 12 abut against the second support plate 122 of the adjacent storage component 12, so that an accommodating space is formed between the adjacent storage components 12; moreover, the structure is simple, easy to assemble and disassemble, and convenient to maintain and replace.

[0119] In one embodiment, a limiting groove 121a is formed at the bottom of the first support plate 121, and a limiting block 123 is formed at the top of the second support plate 122 relative to the limiting groove 121a. When multiple storage components 12 are stacked sequentially along the height direction, the limiting block 123 is inserted into the limiting groove 121a of the adjacent storage component 12.

[0120] The limiting groove 121a formed at the bottom of the first support plate 121 is fitted onto the limiting block 123 of the adjacent lower storage component 12. When multiple storage components 12 are stacked sequentially along the height direction, the limiting block 123 of each storage component 12 will be inserted into the limiting groove 121a of the adjacent storage component 12, thereby ensuring accurate alignment between the storage components 12. Moreover, this design not only improves the stability of the stacking of storage components 12 and prevents tilting or misalignment, but also facilitates quick and accurate assembly and disassembly of the storage components 12.

[0121] like Figure 1 As shown, in one embodiment, the support mechanism 1 further includes two fixed supports 13, a cabinet 14, and multiple cabinet doors 15. The two fixed supports 13 are respectively disposed on the top and bottom of the support platform 11. The cabinet 14 covers the two fixed supports 13 and the support platform 11. The cabinet 14 has a loading port, a unloading port, and a connecting port relative to the loading area 11a, the unloading area, and the space below the support platform 11. The multiple cabinet doors 15 are respectively disposed relative to the loading port, the unloading port, and the connecting port, and are all hinged to the cabinet 14.

[0122] Specifically, the cabinet 14 and cabinet door 15 provide a dustproof and debris-free working environment, which helps to keep the scanning device clean and in good working condition; the fixed bracket 13 enhances the stability of the entire structure, ensuring the stability and safety of the scanning device during operation; the scanned documents can be stored in the space formed by the fixed bracket 13 located below the support platform 11; the design of the loading and unloading ports allows users to easily put in and take out documents.

[0123] It should be understood that the two fixed supports 13 can be of the same structure, or they can be different structures formed by splicing profiles.

[0124] It should be understood that this application may also install cameras (not shown in the figure) above the loading area 11a and the unloading area. The cameras identify the outline and size of the documents to be scanned, and send the size identified by the cameras to the controller (not shown in the figure). The controller then controls the drive unit 538 to open a preset number of suction holes 51a to suction documents of different sizes. The controller may be a processor.

[0125] Furthermore, after the first scanning mechanism 2 and the second scanning mechanism 3 scan the image of the document based on the outline of the document identified by the camera, the scanned image can be cropped according to the outline of the document identified by the camera, so as to avoid the images of stacked documents appearing on different documents.

[0126] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
