[0007] Furthermore, the fixing member includes a magnetic sheet and an iron sheet. The magnetic sheet is fixedly embedded in the top surface of the transparent bottom plate, the iron sheet is fixedly connected to the bottom surface of the transparent pressing plate, and the magnetic sheet is magnetically connected to the iron sheet.

[0008] Furthermore, sliding grooves are opened in the vertical plates on both sides of the U-shaped base, and L-shaped sliding columns corresponding to the positions of the sliding grooves are fixedly connected on both sides of one end of the transparent bottom plate. The L-shaped sliding columns are slidingly and rotatably connected to the sliding grooves, and symmetrically arranged support members are connected to both ends of the U-shaped base, and the support members are staggered.

[0009] Furthermore, the support member includes a support rod, an end of the support rod is fixedly connected to a connecting L block, and the connecting L block is rotatably connected to the outer wall of the U-shaped base.

[0010] Furthermore, a plurality of balls are rotatably embedded on the top surface of the support rod.

[0011] Furthermore, two ends of the transparent pressure plate on the side away from the hinge are fixedly connected with a lifting plate, and anti-slip grooves are provided on both sides of the outer wall of the lifting plate.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] like Figures 1 to 6 As shown, a text recognition device based on image processing includes a scanner body 1 and a mounting base connected to the bottom of the scanner body 1, one side of the mounting base of the scanner body 1 is connected to a U-shaped base 3, a flattening assembly 2 is connected inside the U-shaped base 3, the flattening assembly 2 includes a transparent bottom plate 201 and a transparent pressure plate 202, the transparent bottom plate 201 and the transparent pressure plate 202 are connected to a hinge 203 on one side close to the mounting base, the transparent pressure plate 202 is hinged to the transparent bottom plate 201 through the hinge 203, and the transparent bottom plate 201 and the transparent pressure plate 202 are connected to a fixing member on the side away from the hinge 203.

[0023] like Figure 1 As shown, the text recognition device based on image processing in the utility model is similar to the structure of the existing top-up book and periodical scanner, such as the top-up book and periodical scanner disclosed in the patent with publication number CN218888569U. The main improvement of the utility model is that it is easy to scan wrinkled and folded paper, such as Figures 1 to 5 As shown, when the image processing-based text recognition device in the utility model is in use, when the user uses the scanner body 1, first the transparent pressure plate 202 is rotated open through the hinge 203, and then the wrinkled and folded paper is opened and laid flat on the transparent bottom plate 201, and then the transparent pressure plate 202 is combined with the transparent bottom plate 201, so that the paper is pressed flat by the transparent pressure plate 202, and the transparent pressure plate 202 and the transparent bottom plate 201 are both transparent plates, which will not hinder the normal scanning work of the scanner body 1.

[0024] By arranging a transparent bottom plate 201 and a transparent pressure plate 202 on one side of the mounting seat of the scanner body 1, and by placing the paper on the transparent bottom plate 201, and utilizing the transparent pressure plate 202 and the hinge 203, the hinged transparent pressure plate 202 can completely flatten the folded and wrinkled paper, thereby facilitating scanning of the entire paper without the operator having to manually smooth it, thereby reducing preparatory work and improving scanning efficiency.

[0025] like Figure 1 and Figure 4 As shown, the fixing member includes a magnetic sheet 5 and an iron sheet 8. The magnetic sheet 5 is fixedly embedded in the top surface of the transparent bottom plate 201, and the iron sheet 8 is fixedly connected to the bottom surface of the transparent pressing plate 202. The magnetic sheet 5 is magnetically connected to the iron sheet 8.

[0026] Specifically, when the transparent bottom plate 201 and the transparent pressing plate 202 are combined, the magnetic sheet 5 will be magnetically connected to the iron sheet 8. This arrangement can fix the transparent pressing plate 202 on the transparent bottom plate 201.

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, a slide groove 31 is opened in the vertical plates on both sides of the U-shaped base 3, and L-shaped slide columns 7 corresponding to the position of the slide groove 31 are fixedly connected on both sides of one end of the transparent bottom plate 201. The L-shaped slide column 7 is slidably connected and rotatably connected to the slide groove 31, and symmetrically arranged support members are connected to the two ends of the U-shaped base 3, and the support members are staggered.

[0028] Specifically, when the operator is scanning a paper, the operator can push or pull the transparent pressing plate 202 or the transparent bottom plate 201 to drive the L-shaped slide posts 7 on both sides of one end of the transparent bottom plate 201 to slide in the slide groove 31. This arrangement can facilitate the scanner body 1 to scan the entire paper more comprehensively.

[0029] When it is necessary to scan the other side of the paper, there is no need to remove the paper. You only need to rotate the transparent bottom plate 201 and the transparent pressure plate 202 to drive the L-shaped slide column 7 to rotate in the slide groove 31, so that the transparent bottom plate 201 is turned over. Then, during the scanning process, the transparent bottom plate 201 can be continuously pushed to fully scan the paper. This arrangement makes it easy to scan the back side of the paper without removing the paper and turning it over, thereby improving the scanning efficiency.

[0030] like Figure 6 As shown, the support member includes a support rod 6 , an end of the support rod 6 is fixedly connected to a connection L block 61 , and the connection L block 61 is rotatably connected to the outer wall of the U-shaped base 3 .

[0031] Specifically, when the transparent bottom plate 201 is not flipped, one of the support rods 6 will support the transparent bottom plate 201. When the transparent bottom plate 201 is flipped, the other support rod 6 will support the transparent bottom plate 201. This arrangement prevents the transparent bottom plate 201 from tilting in the U-shaped base 3 only by being limited by the L-shaped sliding columns 7 on both sides of one end.

[0032] like Figure 6 As shown, a plurality of balls 62 are rotatably embedded on the top surface of the support rod 6. With the arrangement of the balls 62, when the transparent bottom plate 201 and the transparent pressing plate 202 slide on the upper surface of the support rod 6, the balls 62 can convert the original sliding friction into rolling friction, thereby improving the smoothness of sliding.

[0033] like Figure 1-Figure 6 As shown, the two ends of the transparent pressing plate 202 away from the hinge 203 are fixedly connected to the lifting plate 4, and the outer wall of the lifting plate 4 is provided with anti-slip grooves on both sides.

[0034] Specifically, when the transparent pressing plate 202 needs to be lifted, it is only necessary to lift the lifting plate 4, thereby driving the transparent pressing plate 202 to rise. This arrangement can facilitate the operator to operate the transparent pressing plate 202.

[0035] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
