[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 protection scope of the present utility model.

[0024] Please see Figure 1-5 The present invention provides the following technical solution:

[0025] A document reader for preventing improper placement and retrieval of documents includes a packaged box 1, a closed cavity 2 inside the packaged box 1, a document positioning slot 3 on the top of the packaged box 1, the depth of the document positioning slot 3 being 3-5mm, the document positioning slot 3 communicating with the closed cavity 2, a document scanning module 4 being provided inside the closed cavity 2, and a glass cover plate 5 embedded in the top of the closed cavity 2, the glass cover plate 5 being located directly below the document positioning slot 3;

[0026] The certificate-taking module 4 includes a camera 401 located on the rear side inside the enclosed cavity 2. A reflective mirror 402 is located on the front side inside the enclosed cavity 2. The reflective mirror 402 is tilted and its vertical projection covers the entire area of ​​the certificate slot 3. A supplementary light 403 is located on the top of the front side inside the enclosed cavity 2. The supplementary light 403 is located on the bottom edge of the certificate slot 3, and the illumination direction of the supplementary light 403 is towards the side of the camera 401.

[0027] In this embodiment: by setting up a packaging box 1, a closed cavity 2, a certificate slot 3, a certificate scanning module 4, and a glass cover 5, the packaging box 1 serves as the main frame of the equipment, providing a stable installation and load-bearing foundation for all components. The user first places the document to be verified into the certificate slot 3 at the top of the packaging box 1. The depth of the certificate slot 3 is set to 3-5mm, and its size is compatible with common documents such as ID cards and driver's licenses. The slot structure can physically limit the document, preventing non-standard placement such as document offset or tilt, guiding the user to naturally achieve "standard positioning upon document placement," without the need for additional adjustments to the placement position. Simultaneously, the certificate slot 3 and the interior of the packaging box 1... The enclosed cavity 2 is connected, and the glass cover 5 embedded in the top of the enclosed cavity 2 is located directly below the document slot 3. The glass cover 5 can prevent external dust and debris from entering the enclosed cavity 2. At the same time, it works with the document slot 3 to hold common documents such as ID cards and driver's licenses. After the document collection process is started, the enclosed cavity 2 plays its role: its sealed structure can isolate external ambient light interference, creating a stable optical environment for the document collection module 4 and avoiding fluctuations in image quality caused by changes in external light intensity. Then the document collection module 4 starts to work, and the supplementary light 403 located at the top front side inside the enclosed cavity 2 (located at the bottom edge of the document slot 3) is activated, and its illumination direction is... Facing the camera 401, the light can precisely cover the document area within the document slot 3, providing a uniform and stable light source for the document and solving the problem of blurred document details caused by insufficient ambient light. Simultaneously, the reflective mirror 402, tilted at the front inside the enclosed cavity 2, can completely cover the entire area of ​​the document slot 3 with its vertical projection. This efficiently reflects the light reflected from the document within the slot 3 (including the light source of the supplementary light 403) to the camera 401 at the rear inside the enclosed cavity 2. Without the need for manual adjustment of the camera 401's angle or focus, the camera 401 can clearly capture the entire document and details of text and patterns through the reflected light path, ensuring accurate information collection. With precision, after data collection, users can simply pick up their documents along the physical contour of the document slot 3. The depth design of the slot facilitates finger insertion for document retrieval while preventing documents from slipping, guiding users to complete the retrieval process correctly. Throughout the process, all structures work together: the encapsulation box 1 integrates all components to ensure overall stability, the sealed cavity 2 protects the optical environment, the document slot 3 ensures proper placement and retrieval, the document imaging module 4 achieves precise imaging, and the glass cover 5 balances protection and light transmission. Without requiring complex operations from the user, the entire process of "standard document placement - precise document collection - standard document retrieval" can be completed, effectively avoiding the impact of non-standard operations on the efficiency and quality of document verification.

[0028] Specifically, such as Figure 2 As shown, the rear side of the top of the packaging box 1 is sprayed with a reading area mark 6, which is marked in white.

[0029] Specifically, such as Figure 5 As shown, the contact area between the positioning groove 3 and the glass cover plate 5 is filled with sealant 7, and the sealant 7 is continuously applied along the contact gap.

[0030] Specifically, such as Figure 4 As shown, a positioning frame 8 is provided on the outer side of the reflective mirror 402, and the bottom of the positioning frame 8 is fixedly connected to the bottom side inside the closed cavity 2.

[0031] In this embodiment: By setting up a document reading area marker 6, sealant 7, and positioning frame 8, the white document reading area marker 6 sprayed on the top rear side of the encapsulated box 1 can quickly guide the user to locate the document slot 3 with its eye-catching color, avoiding misplacement or omission of documents due to not being able to find the placement area, reducing non-standard placement from the initial stage of operation. The sealant 7 continuously filled along the gap between the document slot 3 and the glass cover plate 5 can seal the gap between the two, preventing external dust and moisture from entering the closed cavity 2, preventing impurities from adhering to the reflective mirror 402 or the camera 401 and affecting the image quality, while maintaining the long-term stability of the optical environment inside the closed cavity 2. The bottom of the positioning frame 8 on the outside of the reflective mirror 402 is fixedly connected to the bottom side of the closed cavity 2, which can firmly fix the installation position of the reflective mirror 402, preventing the reflective mirror 402 from shifting during equipment movement or long-term use, ensuring that its tilt angle and vertical projection coverage are always accurate, ensuring the stability of the light reflection path, and providing reliable support for the camera 401 to accurately collect document information.

[0032] Specifically, such as Figure 3 , Figure 4 As shown, the tilt angle of the reflector 402 is 40-50 degrees, and the light source of the supplementary light 403 is an LED light.

[0033] Specifically, such as Figure 3 , Figure 4 As shown, the camera 401 is positioned behind the reflective mirror 402, which reflects the light from the positioning slot 3 onto the imaging surface of the camera 401.

[0034] In this embodiment: When taking a photo, the tilt angle of the reflective mirror 402 is precisely designed to not only fully receive the light reflected from the document in the document slot 3, but also efficiently guide the light to the rear camera 401, avoiding light refraction loss or reflection path deviation. The supplementary light 403 uses an LED light source, which has the characteristics of stable brightness and low energy consumption, and can continuously provide uniform light to the document slot 3 area, solving the problem of blurred document details caused by insufficient ambient light. The camera 401 is set behind the reflective mirror 402, which can accurately receive the light from the document slot 3 transmitted by the reflective mirror 402. Without the need for manual adjustment of the camera 401 angle, the entire appearance of the document and the details of text and patterns can be clearly captured through the reflected light path, ensuring accurate document information collection and greatly reducing the difficulty of operation.

[0035] Specifically, such as Figure 2As shown, the glass cover 5 is made of tempered glass and has a thickness of 3-4 mm.

[0036] In this embodiment: the glass cover 5 is made of tempered glass, which has high strength and impact resistance. It can effectively resist accidental collisions when users place or pick up their documents, preventing the glass cover 5 from breaking and being damaged. At the same time, it prevents external foreign objects from scratching the surface of the cover and affecting light transmission. The 3-4mm thickness design ensures the stability of the cover structure while minimizing the refraction loss of light during transmission. This ensures that the light from the document in the document slot 3 can be clearly transmitted to the reflective mirror 402 inside the closed cavity 2 without affecting the subsequent imaging quality. In addition, this thickness can also provide appropriate protection for the document in the document slot 3, preventing fingers from accidentally touching the internal components of the cavity and further standardizing the operation.

[0037] Working Principle: When using this document reader to prevent improper placement and retrieval of documents, the user is first guided to the document slot 3 by the white document reading area marking 6 sprayed on the top rear side of the encapsulated box 1. This conspicuous color quickly guides the user to the correct placement area, preventing misplacement or omission of documents due to difficulty finding the correct area. This reduces improper placement from the initial stage of operation. The user then places the document to be verified into the document slot 3 on the top of the encapsulated box 1. The depth of the slot 3 is 3-5mm, and its size is compatible with common documents such as ID cards and driver's licenses. The slot structure physically limits the document, preventing it from shifting or tilting. The user does not need to adjust the placement position; the document is automatically positioned correctly upon entering the slot. Simultaneously, directly below the document slot 3 is a glass plate embedded in the top of the enclosed cavity 2. The glass cover 5, made of tempered glass with a thickness of 3-4mm, not only prevents external dust and debris from entering the sealed cavity 2, but also prevents accidental contact with internal components when the user places their ID. The 3-4mm thickness ensures structural stability while minimizing light refraction loss during transmission, thus not affecting subsequent imaging. Next, the ID acquisition process begins. The sealed cavity 2 inside the encapsulation box 1 acts as a seal, isolating external ambient light interference and creating a stable optical environment for the ID-capturing module 4, preventing image quality fluctuations caused by changes in ambient light. Simultaneously, the sealant 7 continuously applied along the seam between the ID slot 3 and the glass cover 5 further seals the gap, preventing external dust and moisture from entering. The enclosed cavity 2 prevents impurities from adhering to the reflective mirror 402 or the camera 401, affecting image formation and maintaining a stable internal optical environment. Then, the document-taking module 4 begins operation: the supplementary light 403 (located at the bottom edge of the document slot 3) on the top front side inside the enclosed cavity 2 is activated. The supplementary light 403 uses an LED light source, providing stable brightness and low energy consumption. Its illumination direction is towards the camera 401, accurately covering the document area within the document slot 3, providing a uniform and stable light source and solving the problem of blurred document details due to insufficient ambient light. At this time, the reflective mirror 402 on the front side inside the enclosed cavity 2 (fixed externally by the positioning frame 8, the bottom of which is connected to the bottom of the enclosed cavity 2 to prevent the reflective mirror 402 from shifting) plays its role. Its 40-50 degree tilt angle is precisely designed, and the vertical projection can completely cover the entire area of ​​the ID card slot 3. It can efficiently guide the light reflected from the ID card in the ID card slot 3 (including the light source of the supplementary light 403) to the camera 401 behind it, avoiding light refraction loss or reflection path deviation. Since the camera 401 is set behind the reflective mirror 402, it can accurately receive the light from the ID card slot 3 transmitted by the reflective mirror 402. There is no need to manually adjust the angle or focus of the camera 401. It can clearly capture the whole picture of the ID card and the details of the text and pattern through the reflected light path, ensuring accurate collection of ID card information. After the collection is completed, the user only needs to pick up the ID card directly along the physical contour of the ID card slot 3. The 3-5mm depth design of the slot body is convenient for the finger to reach in and pick up the document, and also prevents the document from slipping.The system guides users to complete the picking process correctly, while the tempered glass cover 5 protects against accidental impacts during picking, preventing breakage and damage. It also prevents scratches from foreign objects that could affect subsequent use. Throughout the process, the various structures work together seamlessly, allowing users to smoothly complete the entire process of "standardized document placement - accurate document collection - standardized document retrieval," effectively avoiding the impact of non-standard operations on document verification efficiency and quality.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
