Abstract
Description
Technical Field
[0001] This utility model belongs to the field of certificate issuing device technology, and specifically relates to a certificate issuing device. Background Technology
[0002] A document scanner is a scanning device specifically designed for collecting and recognizing document information. It generates document images by taking pictures and scanning them, extracts text information and portraits, converts the images into text using OCR technology, and connects to business systems. It is widely applicable to scenarios such as hotel management, self-service check-in, and government inspection.
[0003] Current document scanning devices generally use a camera mounted on a base to capture images of documents on a table or scanning platform. This type of device is suitable for flat paper documents. However, for book-shaped documents such as passports and household registration books, which are usually folded up, it is difficult to unfold them when scanning. Folding them in the opposite direction can prevent them from folding up, but this can easily damage the book. Pressing them down with your hand can also prevent them from folding up, but this can expose your fingers to the camera, affecting the information capture and resulting in an unsightly image. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a certificate holder, which has a clamp on the cylindrical column of the base for holding the certificate to be scanned, so that the downward projection area of the clamp and the upper surface of the scanning table form an L-shaped clamping cavity, so that the certificate to be scanned can fit in the clamping cavity without the need to prevent it from closing by reverse folding or manual pressing, thus ensuring the integrity of information collection.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A document scanning device includes a base and a cylindrical column. The upper surface of the base is provided with a scanning platform for placing documents to be scanned. The cylindrical column is mounted on the base, and a camera assembly is provided at its upper end, facing the scanning platform. The cylindrical column is provided with a clamp for holding the documents to be scanned. The clamp faces downward, and the downward projection area of the clamp and the upper surface of the scanning platform form an L-shaped clamping cavity, in which the documents to be scanned fit. The clamp has a downward-facing L-shaped structure, and the vertical side of the clamp gradually tapers from top to bottom. The cylindrical column is formed by an upper cylinder and a lower cylinder interlocking with each other. The outer side wall of the upper cylinder is provided with anti-slip texture.
[0007] The camera assembly consists of a camera and a zoom lens. The camera is housed inside the lower cylinder and aligned with an adjustment hole on the lower cylinder. The zoom lens has an internally hollow adjustment post, the external thread of which engages with the internal thread in the adjustment hole. The camera and zoom lens are on the same optical axis and projected onto the scanning stage. The lower end face of the lower cylinder has an adjustment seat, and the adjustment hole is located within the adjustment seat. The camera assembly also includes a protective component, which is a cylindrical structure extending vertically. The protective component fits onto the adjustment seat and encloses the zoom lens. The outer wall of the protective component has an outwardly extending limiting portion, and the limiting portion has a limiting post. The lower cylinder also has a limiting hole, and the limiting post engages within the limiting hole.
[0008] For this type of ID scanner, the primary challenge in scanning booklet-sized documents is preventing them from obstructing the image when folded. With conventional scanners, the document often needs to be fully unfolded (180°) to capture the entire image. If even one side is warped, the image will be partially deformed. Manually pressing down on the warp will result in incomplete data capture. However, bending the document at a 90° angle makes it easier to reshape, and capturing only the flat, horizontal side yields clear and complete information for that page. Therefore, a scanning platform is provided on the upper surface of the base for placing the document on the side to be scanned. The document is placed horizontally on the scanning table, which is the horizontal page. The camera component on the cylinder captures the image information. However, the vertical page on the vertical side of the document to be scanned is prone to falling towards the horizontal page if it is not supported or if one of its pages is too light, thus obstructing the information capture of the horizontal page. Although it can be kept from falling by hand, this will affect the work efficiency. Therefore, a clamp is set on the cylinder. When placing the document to be scanned, the vertical page is inserted into the clamp, and then the horizontal page is placed flat on the scanning table. Thus, the vertical page is restricted by the clamp and will no longer fall, while also keeping the information on the horizontal page intact and improving the efficiency of information capture.
[0009] Since booklet-shaped documents like passports and household registration books can fully display the information on the horizontal pages when opened at a 90° angle, and the size and thickness of these documents are generally consistent, the space required for scanning is fixed. Therefore, the clamp is designed with an L-shaped structure. This provides ample horizontal space when inserting vertical pages, preventing scratches during loading due to excessive narrowness. To avoid overly sharp edges that could scratch the documents, and since the clamp's function is solely to restrict the vertical pages horizontally, the vertical edge of the clamp gradually tapers from top to bottom, minimizing the contact area with the documents. Its rounded edges also prevent scratches. Furthermore, the downward projection area of the clamp and the upper surface of the scanning table form an L-shaped holding cavity, effectively holding the booklet-shaped document within, securing it while simultaneously capturing the information.
[0010] For portability, anti-slip textures are provided on the outer wall of the upper cylinder for easy handling. For immediate use, the distance between the camera in the camera assembly and the scanning table is fixed at the initial assembly stage. Without focusing, it's difficult to capture clear images. Therefore, the zoom lens between the camera and the scanning table adjusts the focal length by changing the distance to the camera. An adjustment seat is provided on the lower cylinder; the internal thread of the adjustment seat engages with the external thread of the adjustment post on the zoom lens. Turning the zoom lens changes the focal length. Once focused, the relative position of the zoom lens remains unchanged. During subsequent document scanning, simply insert the vertical page of the document into the clip and place the horizontal page on the scanning table for rapid scanning without needing to refocus. Even if you take this document scanner to another location, it's plug-and-play without needing to adjust the focus again.
[0011] Since the zoom lens is installed and focused only after the overall assembly of the ID card reader is completed, it is exposed outside the lower cylinder. Although the focal length has been adjusted at the factory, accidental or intentional twisting of the zoom lens during use can cause the camera to lose focus, affecting subsequent document information collection. Therefore, a protective component is installed outside the adjustment base to enclose the zoom lens and prevent accidental twisting. To prevent the protective component from rotating and falling off, a limiting part is added to the protective component. The limiting post on the limiting part cooperates with the limiting hole on the lower cylinder, which strengthens the connection between the protective component and the lower cylinder and increases the difficulty of disassembly.
[0012] Furthermore, it also includes a baffle plate, which is detachably connected to the upper end face of the upper cylinder; the upper cylinder is provided with a first magnet, and the baffle plate is provided with a second magnet, and the baffle plate is attracted to the position of the first magnet in the upper cylinder by the second magnet.
[0013] Compared with the prior art, the advantages of this utility model are as follows: By setting the clamp, the vertical page of the document to be scanned is ensured to be confined within the clamp, while the horizontal page is laid flat on the scanning table for the camera to collect image information. At the same time, the edges of the clamp are rounded to reduce its contact area with the document to be scanned, thus avoiding scratching the page during document collection. In order to enable plug-and-play functionality, since the distance between the camera and the scanning table is fixed, the focal length is adjusted by setting a zoom lens. A protective cover is set on the outside of the zoom lens to prevent defocusing caused by human touch, and a limiting post is added to fit into the limiting hole for reinforcement.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0025] The specific embodiments of this utility model will now be described with reference to the accompanying drawings:
[0026] like Figure 1-8 As shown, a certificate issuing device includes a base 1 and a cylindrical column 2. The upper surface of the base 1 is provided with a scanning table 11 for placing a certificate 3 to be scanned. The cylindrical column 2 is mounted on the base 1, and a camera component 4 is provided at the upper end of the cylindrical column 2, with the camera component 4 facing the scanning table 11. The cylindrical column 2 is provided with a clamp 21 for holding the certificate 3 to be scanned. The clamp 21 faces downward, and the downward projection area of the clamp 21 and the upper surface of the scanning table 11 form an L-shaped clamping cavity 22, in which the certificate 3 to be scanned fits. The clamp 21 has a downward-facing L-shaped structure, and the vertical side 23 of the clamp 21 gradually tapers from top to bottom. The cylindrical column 2 is formed by an upper cylinder 24 and a lower cylinder 25 interlocking with each other. The outer side wall of the upper cylinder 24 is provided with anti-slip texture 242.
[0027] The camera assembly 4 consists of a camera 41 and a zoom lens 42. The camera 41 is disposed inside the lower cylinder 25 and aligned with an adjustment hole 251 on the lower cylinder 25. The zoom lens 42 has an internally hollow adjustment post 421, the external thread of which engages with the internal thread in the adjustment hole 251. The camera 41 and the zoom lens 42 are on the same optical axis and projected onto the scanning stage 11. An adjustment seat 252 is provided on the lower end face of the lower cylinder 25. The adjustment hole 251 is disposed inside the adjustment seat 252. The camera assembly 4 also includes a protective member 43, which is a cylindrical structure extending vertically. The protective member 43 is fitted onto the adjustment seat 252 and encloses the zoom lens 42. The outer side wall of the protective member 43 is provided with an outwardly extending limiting part 431, and the limiting part 431 is provided with a limiting post 432. The lower cylinder 25 is also provided with a limiting hole 253, and the limiting post 432 is fitted into the limiting hole 253.
[0028] Furthermore, it also includes a baffle plate 5, which is detachably connected to the upper end face of the upper cylinder 24; a first magnet 241 is provided inside the upper cylinder 24, and a second magnet 51 is provided on the baffle plate 5. The baffle plate 5 is attracted to the position of the first magnet 241 inside the upper cylinder 24 by the second magnet 51.
[0029] Description of the working principle of this utility model:
[0030] The ID card scanner with this structure has a circuit board inside the base 1 that is electrically connected to the camera 41, providing power and data transmission. Since data transmission and acquisition via the circuit board are existing technologies, their implementation will not be elaborated upon here. For scanning this booklet-shaped ID card, the primary challenge is preventing it from obstructing the image when folded. With ordinary ID card scanners, the document often needs to be fully unfolded 180° flat to capture the entire image. If one side is warped, the entire document will be partially deformed during scanning. Pressing down on it by hand will result in incomplete information capture. However, bending the booklet-shaped document 3 at a 90° angle makes it easier to shape, and capturing only the horizontal, flat side yields clear and complete information for that page. Therefore, a scanning platform 11 is provided on the upper surface of the base 1 for placing the document 3. The document 3 is placed horizontally on the scanning platform 11 with the side to be scanned facing outwards, forming the horizontal page. 32. The camera component 4 on the cylinder 2 captures and acquires image information. However, the vertical page 31 on the vertical side of the document to be scanned 3 is prone to falling towards the horizontal page 32 if it is not supported or if one of its pages is too light, thus obstructing the information acquisition of the horizontal page 32. Although it can be kept from falling by hand, this will affect work efficiency. Therefore, a clamp 21 is set on the cylinder 2. When placing the document to be scanned 3, the vertical page 31 is inserted into the clamp 21, and then the horizontal page 32 is placed flat on the scanning table 11. Thus, the single page of the vertical page 31 is restricted by the clamp 21 and will no longer fall. At the same time, the information display of the horizontal page 32 is kept intact, improving the efficiency of information acquisition.
[0031] Since booklet-like documents such as passports and household registration books can fully display the information on the horizontal page 32 when opened at a 90° angle, and the size and thickness of these document booklets are basically the same, the space required for scanning the document 3 is fixed. Therefore, the clamp 21 is designed with an L-shaped structure. This allows for ample horizontal space when inserting the vertical page 31, preventing it from being too narrow and scratching the document page during loading. To avoid the clamp 21 having overly sharp edges that could scratch the document page, and since the clamp 21's function is only to restrict the vertical page 31 horizontally, the vertical edge 23 of the clamp 21 has a structure that gradually tapers from top to bottom, minimizing the contact area with the document page. At the same time, its rounded edges prevent scratching the document page. In addition, the downward projection area of the clamp 21 and the upper surface of the scanning table 11 form an L-shaped clamping cavity 22, which can effectively hold the booklet-like document inside, completing the information collection while securing the document. In addition, the clamp 21 can be configured as an independent structure that can slide up and down to adjust its position. By clamping it in the movable groove 26 on the cylinder 2, the up and down position can be adjusted to suit different sizes of documents 3 to be scanned.
[0032] For portability, anti-slip texture 242 is provided on the outer wall of the upper cylinder 24 to facilitate hand handling. For immediate use, the distance between the camera 41 in the camera assembly 4 and the scanning table 11 is fixed at the beginning of assembly. Without focusing, it is difficult to capture a clear image. Therefore, the zoom lens 42 between the camera 41 and the scanning table 11 adjusts the focal length by changing the distance between it and the camera 41. An adjustment seat 252 is provided on the lower cylinder 25. The internal thread of the adjustment seat 252 cooperates with the external thread of the adjustment post 421 on the zoom lens 42. The focal length can be changed by turning the zoom lens 42. Once focusing is completed, the relative position of the zoom lens 42 can be kept unchanged. In the subsequent scanning of documents, only the vertical page 31 of the document to be scanned 3 needs to be inserted into the clamp 21, and then the horizontal page 32 is placed on the scanning table 11 for quick scanning without focusing. Even if you take the document scanner to another location, it can be used immediately without adjusting the focal length.
[0033] Since the zoom lens 42 is installed and focused only after the overall assembly of the certificate holder is completed, the zoom lens 42 is exposed outside the lower cylinder 25. Although the focal length has been adjusted at the factory, if the user accidentally or intentionally twists the zoom lens 42 during use, it will cause the camera 41 to lose focus, affecting the subsequent collection of certificate information. Therefore, a protective part 43 is set up. The protective part 43 is fitted outside the adjustment seat 252 to enclose the zoom lens 42 and prevent accidental twisting of the zoom lens 42. In order to prevent the protective part 43 from rotating and falling off, a limiting part 431 is added to the protective part 43. The limiting post 432 on the limiting part 431 cooperates with the limiting hole 253 on the lower cylinder 25, which strengthens the connection between the protective part 43 and the lower cylinder 25 and increases the difficulty of disassembly.
[0034] Because the operating environment of this certificate scanner varies, some locations are exposed to strong light, which can affect the image acquisition of the certificate to be scanned 3. Therefore, a shield 5 is added. By rotatably and detachably connecting it to the upper cylinder 24, it blocks external light during position changes, preventing strong light from affecting image acquisition. To facilitate quick removal of the shield 5, a first magnet 241 is installed inside the upper cylinder 24, and a second magnet 51 is installed on the shield 5. The shield 5 is attracted to the position of the first magnet 241 inside the upper cylinder 24 by the second magnet 51, allowing for easy removal and repositioning.
[0035] Image acquisition in low light conditions can result in poor acquisition quality. Therefore, adding a supplementary light below the lower tube 25 or the protective component 43 can help provide supplementary lighting in darker environments. In particular, using a soft light can provide better illumination and avoid the formation of light spots.
[0036] The beneficial effects of this utility model are as follows: By setting the clamp 21, the vertical page 31 of the document to be scanned 3 is ensured to be confined within the clamp 21, while the horizontal page 32 is laid flat on the scanning table 11 for the camera 41 to collect image information. At the same time, the edge of the clamp 21 is rounded to reduce its contact area with the document to be scanned 3, thus avoiding scratching the page during document collection. In order to enable plug-and-play functionality, since the distance between the camera 41 and the scanning table 11 is fixed, the focal length is adjusted by setting the zoom lens 42. A protective part 43 is set on the outside of the zoom lens 42 to prevent defocusing caused by human touch. A limiting post 432 is added and fitted into the limiting hole 253 for reinforcement. The added shielding plate 5 can effectively block strong light and avoid affecting image collection.
[0037] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it.
