Description

Technical Field

[0001] This utility model relates to the field of imaging equipment technology, specifically to a scanner. Background Technology

[0002] Currently, most flatbed scanners on the market only come with a single-color background board, which is insufficient to meet the scanning needs of different types of documents. There are two main solutions for replacing the background board: one uses a double-sided composite background board, installed via a sliding slot and cover plate. This type of background board is relatively thick, making the overall scanner structure bulky, and the lack of lateral restraint between the background board and cover plate makes it prone to loosening or shifting. The other type uses an adhesive-backed single-color background board, requiring separate purchase of spare background boards of other colors. The adhesive-backed structure is prone to decreased adhesion and wear of the adhesive layer after repeated peeling and pasting, and spare boards are also easily lost. Utility Model Content

[0021] Reference Figure 1The scanner of this application includes a scanning module 10, a cover plate 20, and a background plate assembly 30. The scanning module 10 is the imaging component of the scanner, used to realize document scanning and image acquisition functions. One side of the cover plate 20 is rotatably connected to the scanning module 10 to achieve a rotatable engagement between the cover plate 20 and the scanning module 10. The background plate assembly 30 is disposed inside the cover plate 20. When the cover plate 20 and the scanning module 10 are engaged, the background plate assembly 30 is located between the cover plate 20 and the scanning module 10, so that the first back plate 3 or the second back plate 32 faces the scanning module 10. The background plate assembly 30 can not only flatten the document, but also provide a uniform reference background for the scanning module 10, enabling the scanning module 10 to accurately identify document boundaries and thus obtain a clear image.

[0022] Reference Figure 3 and Figure 4 The background panel assembly 30 includes a first back panel 31 and a second back panel 32 stacked together, and at least one second magnetic member 33 is provided between the first back panel 31 and the second back panel 32. (See reference...) Figure 2 The inner side of the cover plate 20 is provided with at least one first magnetic suction member 21. The background plate assembly 30 is attracted to the inner side of the cover plate 20 by the cooperation of the first magnetic suction member 21 and the second magnetic suction member 33, so as to realize quick and convenient installation and disassembly.

[0023] Specifically, the color of the first backplate 31 is different from the color of the second backplate 32. In this embodiment, one of the first backplate 31 and the second backplate 32 is set to black, and the other to white. Black and white backplates are two commonly used background plates, which can meet the needs of most application scenarios and ensure the versatility and practicality of the background plate assembly 30. Through the magnetic attraction between the first magnetic member 21 and the second magnetic member 33, the background plate assembly 30 can not only be stably installed inside the cover plate 20, but also the installation direction of the background plate assembly 30 can be freely changed, so that the first backplate 31 or the second backplate 32 faces the scanning component, thereby realizing the free replacement of different colored background plates and significantly improving its versatility.

[0024] Preferably, the first back panel 31 and / or the second back panel 32 in this embodiment are made of polypropylene color layer.

[0025] It is understandable that the colors of the first backplate 31 and the second backplate 32 can be flexibly configured according to specific usage scenarios to meet the imaging needs of different scanning objects or environments.

[0026] Furthermore, in this embodiment, both the first magnetic chuck 21 and the second magnetic chuck 33 are magnets. Due to the inherent magnetic properties of the magnets, the first magnetic chuck 21 and the second magnetic chuck 33 can attract each other, ensuring the stability of the connection between the background plate assembly 30 and the cover plate 20.

[0027] Reference Figure 2 The inner side of the cover plate 20 is provided with four first magnetic suction members 21 arranged in a rectangular shape, as shown in the figure. Figure 4 The background panel assembly 30 includes four second magnetic members 33 arranged in a rectangular pattern. (See reference...) Figure 2 Second magnetic accumulator 33 (refer to) Figure 3 The positions of the components are respectively corresponding to the positions of the first magnetic component 21 to ensure that the background plate assembly 30 can be accurately attached to the cover plate 20.

[0028] Specifically, refer to Figure 5 and 6 In this embodiment, the first magnetic clasp 21 and the second magnetic clasp 33 are arranged and installed in a specific manner. Inside the cover plate 20, the magnetic poles of adjacent first magnetic clasp 21 facing the background plate assembly 30 are opposite. That is, of the four first magnetic clasp members inside the cover plate 20, the magnetic poles of two first magnetic clasp members 21 located on the same diagonal face the same direction, and the magnetic poles of first magnetic clasp members 21 located on different diagonals face different directions. Correspondingly, inside the background plate assembly 30, the magnetic poles of adjacent second magnetic clasp members 33 facing the same side are opposite, and the magnetic poles of each second magnetic clasp member 33 facing the first back plate 31 are opposite to those facing the second back plate 32, in order to match the arrangement of the first magnetic clasp members 21.

[0029] Understandably, referring to Figure 5 and Figure 6 When arranging the second magnetic components 33, the arrangement order needs to be adjusted according to the orientation of the first magnetic components 21 to ensure that the background plate assembly 30 can be attracted to the cover plate 20.

[0030] In this embodiment, the configuration of the first magnetic component 21 and the second magnetic component 33 allows for magnetic connection by simply aligning the length of the background panel assembly 30 with the length of the cover plate 30 during installation, without needing to consider the vertical orientation. This method not only ensures the stability of the connection but also simplifies the installation process of the background panel assembly 30, making it quicker and more convenient.

[0031] In another embodiment, one of the first magnetic chuck 21 and the second magnetic chuck 33 is a magnet, and the other is a magnetic conductor. The magnet (such as neodymium iron boron, ferrite, or other permanent magnet materials) generates a stable magnetic field, while the magnetic conductor (such as pure iron, low-carbon steel, or other soft magnetic materials) does not generate a magnetic field but can be attracted to the magnet. When the first magnetic chuck 21 (or the second magnetic chuck 33) is a magnet, both magnetic poles of the second magnetic chuck 33 (or the first magnetic chuck 21) can be attracted to the first magnetic chuck 21. Therefore, regardless of how the background panel assembly 30 is flipped, the second magnetic chuck 33 can always be attracted to the first magnetic chuck 21, eliminating the need for specific requirements on the direction of the magnetic poles. This design eliminates the need to consider the orientation of the magnetic poles, improving installation flexibility. In this embodiment, the positions of the first magnetic chuck 21 and the second magnetic chuck 33 are arranged in a one-to-one correspondence. Each first magnetic chuck 21 has a corresponding second magnetic chuck 33, ensuring a stable and effective magnetic connection between them.

[0032] It is worth noting that the specific positions and quantities of the first magnetic component 21 and the second magnetic component 33 can be flexibly adjusted according to the needs of actual application scenarios to meet different design requirements. Therefore, this application does not limit the specific positions and quantities of the first magnetic component 21 and the second magnetic component 33.

[0033] Reference Figure 2 At least one mounting groove 22 is recessed on the inner side of the cover plate 20 (i.e., the side of the cover plate 20 facing the scanning module 10), and the first magnetic suction member 21 is correspondingly disposed in the mounting groove 22. When the first magnetic suction member 21 is assembled, its outer surface is at the same horizontal plane as the groove opening of the mounting groove 22 to maintain flushness. This structural design ensures that a stable magnetic connection can be formed between the first magnetic suction member 21 and the second magnetic suction member 33, ensuring the reliability of the assembly of the cover plate 20 and the background plate assembly 30. Furthermore, by controlling the installation height of the first magnetic suction member 21, the cover plate 20 and the background plate assembly 30 maintain good coordination in their overall structure. Thus, when the background plate assembly 30 applies pressure to the document on the scanning module 10, it ensures a flat and close fit while avoiding interference with the normal imaging or scanning performance of the scanning module 10 due to excessive contact.

[0034] Reference Figure 2 The cover plate 20 also has at least one positioning element 23 on its inner side. The background panel assembly 30 abuts against the positioning element 23, enabling precise positioning of the background panel assembly 30 during installation, thereby improving the installation efficiency of the background panel assembly 30. (Refer to...) Figure 2In this embodiment, the positioning member 23 is designed as an L-shaped structure, and the corner part of the positioning member 23 corresponds to the corner part of the background plate assembly 30 installed on the cover plate 20, so as to achieve effective positioning of the background plate assembly 30 in the length and width directions, and at the same time provide additional limiting functions to ensure the stability of the background plate assembly 30.

[0035] Optionally, the number and layout of the positioning elements 23 can be flexibly adjusted according to specific application requirements. For example, two opposing positioning elements 23 can be set along the diagonal direction of the background panel assembly 30; or two opposing positioning elements 23 can be set along the length or width direction of the background panel assembly 30; or four positioning elements 23 can be set, corresponding to the four corner positions of the background panel assembly 30 respectively. In addition, the specific shape of the positioning elements 23 is not limited to L-shape, and can also be selected in different forms such as cylindrical or strip shape according to design requirements, so as to adapt to different assembly requirements and optimize the overall structural coordination.

[0036] Reference Figure 3 and Figure 4 In this embodiment, a buffer layer 34 is provided between the first back plate 31 and the second back plate 32. This not only facilitates pressing the document and making it flat and adhered to the scanning module 10, but also effectively prevents damage to the scanning module 10. Furthermore, the second magnetic components 33 are all embedded within the buffer layer 34, ensuring the stability of the installation of the second magnetic components 33 and minimizing the impact of the background plate assembly 30 on the scanning module 10 when the cover plate 20 is fastened, thereby preventing potential damage.

[0037] Preferably, the buffer layer 34 in this embodiment is a polyurethane foam buffer layer.

[0038] This application's scanning technology utilizes two different colored back panels on the background panel assembly and the magnetic attraction between the first and second magnetic components to facilitate easy replacement of the two colored background panels. Furthermore, the special arrangement of the first and second magnetic components not only ensures the stability of the connection between the background panel assembly and the cover plate but also improves the portability of installing and removing the background panel assembly.

[0039] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
