Description

TECHNICAL FIELD

[0001] The present application relates to the field of archiving equipment, in particular to a continuous photographing device for paper documents and a continuous photographing method for paper documents. BACKGROUND

[0002] In various scenarios such as government affairs, enterprise office, and financial services, the amount of paper documents continues to grow as the complexity and scale of business expand. These paper documents include not only important materials with legal effect such as policy documents, contracts, and approval materials, but also documents that need to be kept for a long time such as daily office records and business vouchers. The security and traceability of these documents directly affect the standardization of business development. It has become an industry consensus to convert paper documents into electronic data for archiving. Electronic storage not only greatly improves the storage life of documents, but also enables quick retrieval, sharing, and backup through digital indexing, reducing management costs.

[0003] As the core output device in office scenarios, a desktop printer usually includes four core parts: a housing, a paper feeding assembly, a printing assembly, and a paper output assembly. The housing provides support and protection for the overall device and forms a closed working space inside. The paper feeding assembly is composed of a paper tray, a paper rubbing wheel, and a guide shaft. The paper rubbing wheel rotates to send the paper in the paper tray into the device one by one for laser or inkjet printing.

[0004] However, the current desktop printers on the market, especially the mainstream models in the mid-to-low-end segment, generally focus their functional design on the core printing needs, and most of them do not have built-in scanning functions. After printing, users need to manually remove the paper from the paper tray and place it in a scanning device or a high-speed scanner, which not only increases the manual transfer steps but also easily causes paper sequence disorder, omission, and other problems, making the processing efficiency of multi-page documents extremely low. SUMMARY

[0005] The present application provides a continuous photographing device for paper documents to address the inconvenience of not having scanning functions in current desktop printers when photographing or scanning documents for archiving.

[0006] To solve the above problems, the technical scheme adopted by the present application is a paper document continuous photographing device, which comprises a shell, a paper channel is formed through the front and back of the shell, the inner cavity bottom surface of the shell forms a paper placement surface, a camera module is arranged on the inner top surface of the shell, and the shooting direction of the camera module faces the placement surface; a pushing assembly and a stop assembly are arranged at the bottom of the shell; the pushing assembly is located at the entrance end of the paper channel, the pushing assembly comprises a linear reciprocating mechanism, a pushing plate is arranged at the moving end of the linear reciprocating mechanism, the pushing plate is located at least partially above the placement surface, and the moving direction of the linear reciprocating mechanism is arranged along the paper conveying direction; the stop assembly is located at the exit end of the paper channel, the stop assembly comprises a lifting mechanism, a baffle is arranged at the lifting end of the lifting mechanism, the highest position of the baffle is above the placement surface, and the lowest position of the baffle is below the placement surface; a paper detection sensor and a paper in-place sensor are further arranged on the bottom plate of the shell, the paper in-place sensor is arranged close to the exit of the paper channel, and the paper detection sensor is arranged close to the entrance of the paper channel. After the paper enters the paper channel from the paper outlet of the printer, the paper detection sensor at the entrance is first triggered, the sensor sends a signal to start the linear reciprocating mechanism of the pushing assembly, the pushing plate pushes the paper to move towards the exit end along the paper conveying direction; when the paper moves to the exit end, the paper in-place sensor is triggered, at this time, the lifting mechanism of the stop assembly drives the baffle to rise above the placement surface, and the paper is accurately positioned at the photographing position; after the photographing is completed, the baffle is lowered below the placement surface, the pushing plate continues to push the paper out of the exit end, and the single-time conveying-positioning-photographing-paper-out process is completed. The seamless connection of the printer and the photographing device is realized, the paper does not need to be manually transferred, the sequence disorder or omission of multiple pages of documents is avoided, the automatic conveying and accurate positioning of the paper are realized through the cooperation of the double sensors and the pushing and stopping assemblies, the continuous processing efficiency is greatly improved, the overall structure is compact, the installation scene of the desktop printer is adapted, and too much office space is not additionally occupied.

[0007] As a preferred implementation scheme of a paper file continuous shooting device, the bottom of the shell is provided with a mounting box, the second motor is arranged in the mounting box, the output shaft of the second motor is provided with a rotating shaft connecting rod, one end of the rotating shaft connecting rod is fixedly connected with the output shaft of the second motor through a shaft sleeve, the pushing plate is provided with a first long hole, the first long hole is perpendicular to the paper conveying direction, the other end of the rotating shaft connecting rod is movably arranged in the first long hole through a flange bearing, and the two side edges of the pushing plate are in contact with the inner side wall of the mounting box and realize guiding. After the second motor is started, the output shaft drives the rotating shaft connecting rod to rotate around the motor shaft. Since the other end of the rotating shaft connecting rod is embedded in the first long hole of the pushing plate through the flange bearing, the rotating motion is converted into the linear reciprocating motion of the pushing plate along the paper conveying direction. The inner side wall of the mounting box guides and restricts the two side edges of the pushing plate, so that the pushing plate always moves along the preset path and avoids deviation. Through the transmission structure of the motor + rotating shaft connecting rod + long hole, the stable reciprocating motion of the pushing plate is realized, the transmission efficiency is high, and the noise is small. The cooperation of the shaft sleeve and the flange bearing reduces the motion wear and prolongs the service life of the assembly. The motion track of the pushing plate is accurate, the stability of paper conveying is guaranteed, and paper jamming or positioning deviation is avoided.

[0008] As a preferred implementation scheme of a paper file continuous shooting device, the side wall of the mounting box is provided with a second long hole, the side surface or the bottom surface of the pushing plate is provided with a bearing guide wheel, the bearing guide wheel is located in the second long hole and is in rolling contact with the inner edge of the second long hole. When the pushing plate moves linearly, the bearing guide wheel on the side surface or the bottom surface rolls along the inner edge of the second long hole of the mounting box side wall, the extension direction of the second long hole is consistent with the paper conveying direction, and the pushing plate is guided and restricted twice; rolling contact replaces sliding contact, and the friction resistance of the pushing plate during movement is reduced. Further improve the straightness and stability of the pushing plate movement, avoid the guide gap becomes larger due to long-term use; the rolling friction greatly reduces the energy consumption and the wear of the components, prolongs the maintenance period of the device; the cooperation of the guide wheel and the second long hole can absorb the slight assembly error and improve the assembly adaptability.

[0009] As a preferred implementation scheme of a paper file continuous shooting device, the bottom surface of the pushing plate is provided with at least two auxiliary wheels on both sides, and the auxiliary wheels are in rolling contact with the inner side wall of the mounting box. When the pushing plate moves, the auxiliary wheels on both sides of the bottom surface keep rolling contact with the inner side wall of the mounting box, and support and guide the pushing plate from the bottom; the multiple auxiliary wheels are uniformly distributed, so that the pushing plate is balanced and avoids tilting or jamming during movement. Disperse the stress of the pushing plate, prevent the movement from being stuck due to uneven stress on one side; the rolling support of the auxiliary wheel further reduces the friction coefficient, so that the pushing action is smoother and the response is faster.

[0010] As a preferred embodiment of a continuous photographing device for paper documents, the lifting mechanism includes a fixed plate installed at the bottom of the housing. A push-pull electromagnet is mounted on the bottom surface of the fixed plate, and the push-pull electromagnet is horizontally positioned. A connecting plate is provided at the moving end of the push-pull electromagnet, and a third elongated hole is formed on the connecting plate, which is vertically positioned. The middle part of a baffle is hinged to the fixed plate, and the lower part of the baffle is movably installed in the third elongated hole via bolts. After the paper is in place, the push-pull electromagnet is energized to generate attraction, pulling the connecting plate horizontally. Because the middle part of the baffle is hinged to the fixed plate, and the lower part is bolted into the vertical third elongated hole of the connecting plate, the horizontal movement of the connecting plate is converted into the rotational lifting of the baffle around the hinge point. When stopping is required, the baffle rotates to above the placement surface; when releasing is required, the electromagnet is de-energized, and the baffle rotates to below the placement surface under the action of gravity or a restoring force. The push-pull electromagnet has a fast response speed, enabling rapid raising and lowering of the baffle, which meets the high-efficiency requirements of continuous photography; the hinged + elongated hole transmission structure is simple and reliable with a low failure rate; the baffle raising and lowering action is precise, ensuring the stability of the paper's positioning at the shooting position and preventing the paper from shifting during shooting.

[0011] As a preferred embodiment of a continuous photographing device for paper documents, the camera module includes a module fixing plate mounted on the top of the housing. An adjustment plate is mounted on the bottom surface of the module fixing plate, and a lifting assembly is mounted on the side of the adjustment plate. A camera is mounted on the lifting end of the lifting assembly. The housing also includes a fill light and a manual dimming switch. Before taking a picture, the camera module adjusts the camera height via the lifting assembly based on the paper size information fed back by the paper detection sensor, ensuring the camera maintains the optimal shooting distance from the paper. The fill light automatically adjusts its brightness according to the ambient light and can also be manually fine-tuned via the manual dimming switch to ensure uniform lighting in the shooting area. The camera height is flexibly adjustable to adapt to paper documents of different sizes, ensuring accurate image proportions. The automatic + manual dimming mode of the fill light solves the problem of blurry images caused by insufficient ambient light or reflections, improving the clarity of electronic documents. The modular design facilitates installation and maintenance, reducing subsequent repair costs.

[0012] In a preferred embodiment of a continuous photographing device for paper documents, a straightening component is also provided in the placement surface. The straightening component includes two push plates, located on opposite sides inside the housing. A drive wheel and a driven wheel are rotatably mounted on the bottom surface of the housing. The drive wheel is connected to a first motor. A synchronous belt is mounted around both the drive wheel and the driven wheel, and the synchronous belt is tensioned to form two straight sections. The two push plates are fixedly connected to the two straight sections via push plate connectors. When the camera module detects that the paper is tilted, it sends a signal to start the first motor. The first motor drives the drive wheel to rotate, and the synchronous belt achieves cyclical motion through the cooperation of the drive wheel and the driven wheel. Since the two push plates are respectively connected to the two straight sections of the synchronous belt, the movement of the synchronous belt drives the two push plates to move synchronously towards the center, applying a uniform pushing force from both sides of the paper to straighten the tilted paper to the preset shooting position. It achieves automated paper tilt correction, eliminating the need for manual adjustment and significantly improving processing efficiency; synchronous belt drive ensures strong synchronization of the two push plates, uniform alignment force, and avoids paper wrinkling or damage; it is adaptable to different paper widths, has strong versatility, and meets diverse office needs.

[0013] In a preferred embodiment of a continuous photographing device for paper documents, multiple nozzles are mounted on the bottom plate of the housing, with the air outlets of the nozzles located within the placement surface. When the camera module detects that the paper is bent or curled at the edges, it sends a signal to activate the nozzles. The nozzles blow a uniform airflow onto the bent portion of the paper, causing the bent paper to flatten back onto the placement surface under the action of the airflow. After blowing is complete, the nozzles stop working, and the camera module checks the paper's condition again to ensure that it meets the requirements for photographing.

[0014] On the other hand, the present invention also provides a method for continuous photographing of paper documents, including the following steps: S1. Connect the continuous photographing device for paper documents to the printer, so that the printer's paper output port is connected to the inlet end of the paper channel; S2. After starting the printing job, the paper enters the housing from the printer and falls into the placement surface. After the paper detection sensor detects the paper, the linear reciprocating mechanism is activated, and the pusher plate pushes the paper to the outlet end of the paper channel. At this time, the paper is blocked by the baffle and reaches the photographing position; S3. The camera module identifies the paper's position. If the paper is tilted, the straightening component is activated, and the two pushers move towards the center to straighten the paper; S4. The camera module is raised and lowered to a suitable position to photograph the paper; S5. The baffle is lowered, and the pusher plate pushes the paper out from the outlet of the paper channel; S6. Repeat steps S2-S5 to complete the photographing and saving of the entire document. This method greatly improves office efficiency; the entire process is automated, reducing the risk of document sequence disorder, omission, or damage caused by manual operation; it is suitable for batch document processing scenarios, especially for government, enterprise, and other office environments with a high density of paper documents.

[0015] In step S3, the camera module identifies whether the paper is bent. If the paper is bent, the nozzle is activated to blow air into the paper and then drop it back down, restoring the paper to a flat state. Adding a bend correction step before straightening further improves the standardization of the paper's image state, avoiding problems such as blurred images and missing content caused by bending. The air-blowing correction method is fast and efficient, without affecting the overall continuous processing rhythm. It eliminates the need for manual paper smoothing, lowering the operational threshold and enhancing the automation and practicality of the device.

[0016] As can be seen from the above technical solutions, the advantages of this invention are as follows: This device can achieve seamless connection between the printer and the camera, eliminating the need for manual paper transfer and avoiding the disorder or omission of multiple pages of documents. Its compact structure is suitable for desktop installation and does not occupy excessive office space. Through the combination of dual sensors and push / stop components, automated paper feeding and precise positioning can be achieved, significantly improving continuous processing efficiency. The push component uses a transmission structure of motor + rotating shaft connecting rod + elongated hole, enabling smooth reciprocating motion of the push plate with high transmission efficiency and low noise. The cooperation between the bushing and flange bearing reduces wear and extends the component's lifespan. The bearing guide wheel on the side wall of the mounting box, in cooperation with the second elongated hole, further improves the straightness and stability of the push plate's movement, reduces energy consumption and component wear, and absorbs minor assembly errors. The auxiliary wheel on the bottom of the push plate disperses force, preventing movement jamming caused by uneven force on one side, making the pushing action smoother. The push-pull electromagnet of the stop component has a fast response speed, enabling rapid raising and lowering of the stop plate to meet continuous photography needs. The hinged + elongated hole design further enhances the paper's smoothness and stability. The hole's transmission structure is simple, reliable, and has a low failure rate, ensuring the stability of the paper's positioning at the shooting position. The camera module can flexibly adjust its height according to the paper size, ensuring accurate imaging proportions. The automatic and manual dimming modes of the supplementary light can solve ambient light problems to improve the clarity of electronic documents. The modular design also facilitates installation and maintenance. The alignment component can automatically correct paper tilt without manual adjustment. The synchronous belt drive ensures strong synchronization and uniform force of the push plate movement, avoiding paper wrinkles and adapting to different paper widths, making it highly versatile. The nozzle on the bottom plate of the housing can handle paper bending and curling before alignment, improving the standardization of the shooting state. The correction method is fast and efficient and does not affect the overall processing rhythm. The corresponding continuous shooting method for paper documents simplifies multi-step operations into an integrated process, greatly improving office efficiency. The fully automated processing reduces the risk of document sequence disorder, omission, or damage caused by manual operation. It is especially suitable for batch processing scenarios with intensive paper documents in government and enterprises, reducing the overall operating threshold and subsequent maintenance costs, and demonstrating outstanding practicality and reliability.

[0025] To make the objectives, features, and advantages of this patent more apparent and understandable, the technical solutions of this patent will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this patent, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0026] Example 1 like Figures 1-6 As shown, a continuous photographing device for paper documents includes a housing 2, which forms a paper channel 00 through the front and back. The bottom surface of its inner cavity forms a paper placement surface 01. The overall structure is compact and adaptable to desktop printer installation scenarios, requiring minimal additional office space. It achieves seamless integration with the printer, avoiding issues such as disordered or missed pages due to manual paper handling. The top surface inside the housing 2 is equipped with a camera module 02 with its shooting direction facing the placement surface 01. The camera module 02 includes a module fixing plate 6 mounted on the top of the housing 2. An adjustment plate 7 is installed on the bottom surface of the fixed plate 6, and a lifting assembly 4 is installed on the side of the adjustment plate 7. A camera 3 is installed on the lifting end of the lifting assembly 4. The housing 2 is also equipped with a fill light 5 and a manual dimming switch 1. The lifting assembly 4 can flexibly adjust the height of the camera 3 according to the size of the paper to ensure accurate imaging ratio of different paper sizes. The automatic + manual dimming mode of the fill light 5 can effectively solve the problem of blurry imaging caused by insufficient ambient light or reflection, significantly improving the clarity of electronic documents. The modular structural design also facilitates later installation and maintenance, reducing maintenance costs.

[0027] The bottom of the housing 2 is provided with a pushing component 03 located at the inlet end of the paper channel 00 and a stop component 04 located at the outlet end of the paper channel 00. The pushing component 03 includes a linear reciprocating mechanism. The moving end of the linear reciprocating mechanism has a pushing plate 22 located at least partially above the placement surface 01 and moving in the direction of paper feeding. The bottom of the housing 2 is also provided with a mounting box 21. A second motor 30 is installed inside the mounting box 21. The output shaft of the second motor 30 is fixedly connected to a rotating shaft connecting rod 24 via a bushing 28. The pushing plate 22 has a first elongated hole 29 perpendicular to the paper feeding direction. The other end of the rotating shaft connecting rod 24 is movably installed in the first elongated hole 29 via a flange bearing 23. This transmission structure of motor + rotating shaft connecting rod + elongated hole enables smooth reciprocating motion of the pushing plate 22, with high transmission efficiency and low noise. The cooperation between the push plate 22 and the flange bearing 23 can reduce motion wear and extend the service life of the component. At the same time, the two side edges of the push plate 22 contact the inner side wall of the mounting box 21 and provide guidance. The side wall of the mounting box 21 is also provided with a second elongated hole 27. The side or bottom surface of the push plate 22 is equipped with a bearing guide wheel 26 located in the second elongated hole 27 and rolling in contact with the inner edge of the second elongated hole 27. The bottom surface of the push plate 22 is also provided with at least two auxiliary wheels 25 on both sides, which rolling in contact with the inner side wall of the mounting box 21. The cooperation between the bearing guide wheel 26 and the second elongated hole 27 further improves the straightness and stability of the push plate 22. The auxiliary wheels 25 can distribute the force on the push plate 22 and prevent motion jamming caused by uneven force on one side. The two together reduce the coefficient of friction, making the pushing action smoother and the response faster, ensuring stable paper feeding, and avoiding paper jams or positioning deviations.

[0028] The stop assembly 04 includes a lifting mechanism. The lifting end of the lifting mechanism is provided with a baffle 17. The highest position of the baffle 17 is located above the placement surface 01, and the lowest position is located below the placement surface 01. The lifting mechanism specifically includes a fixed plate 18 installed at the bottom of the housing 2. A horizontally arranged push-pull electromagnet 20 is installed on the bottom surface of the fixed plate 18. The moving end of the push-pull electromagnet 20 is provided with a connecting plate 19. A vertically arranged third elongated hole 31 is opened on the connecting plate 19. The middle part of the baffle 17 is hinged to the fixed plate 18, and the lower part is movably installed in the third elongated hole 31 by bolts. The push-pull electromagnet 20 has a fast response speed and can realize the rapid lifting and lowering of the baffle 17, which perfectly meets the high-efficiency requirements of continuous photography. The transmission structure of hinge + elongated hole is simple, reliable, and has a low failure rate, which can ensure the positioning stability of the paper at the shooting position and avoid paper displacement during shooting.

[0029] The placement surface 01 is equipped with a straightening component, which includes two push plates 9 located on both sides inside the housing 2. A drive wheel 14 and a driven wheel 12 are rotatably mounted on the bottom surface of the housing 2. The drive wheel 14 is connected to a first motor 11, and a synchronous belt 13, which is tensioned to form two straight sections, is mounted around the drive wheel 14 and the driven wheel 12. The two push plates 9 are fixedly connected to the two straight sections through push plate connectors 15. The synchronous belt 13 transmission ensures strong synchronization of the movement of the two push plates 9, which can automatically correct the paper tilt state without manual adjustment, greatly improving processing efficiency. The straightening force is uniform, which can effectively avoid paper wrinkles or damage. At the same time, it is compatible with paper of different widths, has strong versatility, and meets diverse office needs.

[0030] In addition, the bottom plate of the housing 2 is also equipped with multiple air nozzles 10 located in the placement surface 01, as well as a paper detection sensor 8 located near the inlet of the paper channel 00 and a paper positioning sensor 16 located near the outlet of the paper channel 00. The air nozzles 10 can be activated when the camera module 02 detects that the paper is bent or curled at the edge. The airflow is used to flatten the paper again, which further improves the standardization of the paper's shooting state before straightening, avoiding blurry images and missing content caused by bending. The correction method is fast and efficient and does not affect the overall continuous processing rhythm. The paper detection sensor 8 and the paper positioning sensor 16 work with the push component 03 and the stop component 04 to realize fully automated paper delivery and precise positioning, further improving continuous processing efficiency. The fully automated operation not only reduces the threshold of manual operation, but also reduces the risk of document damage, and is especially suitable for batch processing scenarios with intensive paper documents in government affairs, enterprises and other fields.

[0031] The usage process in this embodiment is as follows: The process of using this continuous photographing device for paper documents requires first connecting the device to a desktop printer, aligning the printer's paper output port with the inlet end of the device's paper channel 00 to establish a seamless "print-photograph" connection. Then, the printer is started, and paper enters the paper channel 00 from the printer's output port and falls onto the placement surface 01 inside the housing 2. At this point, the paper detection sensor 8 near the channel inlet detects the paper and immediately triggers the push assembly 03 to operate—the second motor 30 starts, and through the cooperation of the rotating shaft connecting rod 24 and the first elongated hole 29 on the push plate 22, the paper is... The rotational motion is converted into linear motion of the pusher plate 22 along the paper feeding direction. The pusher plate 22 pushes the paper towards the channel outlet. At the same time, the bearing guide wheel 26 on the side wall of the mounting box 21 cooperates with the auxiliary wheel 25 on the bottom surface of the pusher plate 22 to ensure smooth movement of the pusher plate 22 and avoid paper deviation or jamming. When the paper is pushed to the channel outlet, the paper positioning sensor 16 near the outlet is triggered, and the push-pull electromagnet 20 of the stop assembly 04 is energized. Through the hinge transmission between the connecting plate 19 and the baffle 17, the baffle 17 is driven to rise above the placement surface 01, accurately limiting the paper. Positioned at the camera location, the camera module 02 then activates to identify the paper's condition: if it detects bending or curling edges, the nozzle 10 at the bottom of the device sprays out a uniform airflow to flatten the paper again; if it detects tilting (the angle between the long side and the vertical plane is greater than 10°), the first motor 11 of the straightening component starts, driving the drive wheel 14 and driven wheel 12 to rotate, and the synchronous belt 13 drives the push plates 9 on both sides to move towards the center to smoothly straighten the paper; once the paper condition meets the requirements, the lifting component 4 of the camera module 02 adjusts the height of the camera 3 according to the size of the paper to maintain the optimal shooting distance and provides supplementary lighting. The light 5 automatically adjusts its brightness according to the ambient light (or can be finely adjusted by the manual dimming switch 1) to ensure uniform lighting in the shooting area. Then, the camera 3 completes the electronic photography of the paper document. After the photography is completed, the push-pull electromagnet 20 is de-energized, the baffle 17 is lowered below the placement surface 01, the push component 03 is restarted, and the push plate 22 pushes the photographed paper out of the channel outlet. After that, the device automatically repeats the above "paper conveying-positioning correction-photographing-discharging" process until all the papers of the entire document have been photographed and archived, realizing the automated electronic processing of batch paper documents.

[0032] Example 2 This embodiment further provides a method for continuous photography of paper documents, including the following steps: S1. Connect the continuous paper document photographing device to the printer, so that the printer's paper output port is connected to the inlet end of the paper path 00; S2. After the printing job is started, the paper enters the housing 2 from the printer and falls into the placement surface 01. After the paper detection sensor 8 detects the paper, the linear reciprocating mechanism is started, and the push plate 22 pushes the paper to the exit end of the paper channel 00. At this time, the paper is blocked by the baffle 17 and reaches the photo taking position. S3. The camera module 02 identifies the position of the paper. If the paper is tilted, the straightening component is activated, and the two push plates 9 move towards the center to straighten the paper. At the same time, the camera module 02 identifies whether the paper is bent. If the paper is bent, the nozzle 10 is activated to blow air into the paper and then drop it back down to restore the paper to a flat state. S4. The camera module 02 is raised and lowered to a suitable position to take a picture of the paper; S5. The baffle 17 drops, and the pusher plate 22 pushes the paper out from the exit of the paper channel 00; S6. Repeat steps S2-S5 to complete the photo saving of the entire document.

The auxiliary wheel on the bottom surface of the push plate can distribute the force and prevent movement jamming caused by uneven force on one side, making the push action smoother; the push-pull electromagnet of the stop component has a fast response speed, which can realize the rapid lifting and lowering of the baffle to adapt to the needs of continuous photography, and the hinge + The elongated transmission structure is simple, reliable, and has a low failure rate, ensuring stable paper positioning at the shooting position. The camera module can flexibly adjust its height according to the paper size, ensuring accurate imaging proportions. The automatic and manual dimming modes of the supplementary light can solve ambient light problems to improve the clarity of electronic documents.
