[0027] It should be pointed out that the following detailed description is all exemplary, and aims to provide further explanation of the present application. Unless otherwise specified, all the technical and scientific terms used in the present application have the same meaning as that generally understood by the ordinary skilled in the art to which the present application belongs. In addition, it should be understood that when the terms "comprise" and / or "include" are used in the present specification, they indicate the presence of a feature, step, operation, device, component and / or their combination.

[0028] In order to solve the technical problems mentioned in the background art, the present application provides a scanning device with a support assembly 4. As shown in Figure 1 、 Figure 2 、 Figure 3 , the scanning device comprises a paper feeding platform 1, a scanning unit 2 and a paper discharging platform 3. The paper feeding platform 1 is arranged on the upper side of the rear end of the scanning unit 2, used for placing the paper to be scanned, and guiding the paper into the scanning unit 2. The scanning unit 2 completes the scanning work of the paper, and the paper discharging platform 3 is arranged on the lower side of the front end of the scanning unit 2, receiving the scanned paper and outputting it.

[0029] The support assembly 4 is located at the position where the bottom surface of the scanning unit 2 is connected with the paper output platform 3, and comprises a support frame 41 and a support leg 42. The support frame 41 is fixedly installed at the bottom of the scanning unit 2 and is connected with the support leg 42. The support leg 42 is installed at both ends of the support frame 41 and is used to support the front end of the scanning unit 2, so that the front end is rotated to a predetermined angle relative to the rear end. The structure design effectively adjusts the height difference between the front end and the rear end of the scanner, so as to optimize the entering and output angles of the paper and reduce the paper jam phenomenon in the scanning process. In particular, when scanning A3 large paper, the paper passing rate can be significantly improved, and the scanning fluency is ensured.

[0030] As shown in Figure 5 , Figure 6 In the embodiment, the end of the support frame 41 is provided with a pin hole, and the top of the support leg 42 is also provided with a pin hole. The support frame 41 and the support leg 42 are connected by a pin shaft, so that the support leg 42 can rotate around the pin shaft at the end of the support frame 41. The design of the rotating connection allows the support leg 42 to be rotated and withdrawn to the bottom of the scanner when it is not needed, so as to facilitate the withdrawal of the support leg 42 when the scanner is not used to scan the wrinkled test paper, and to realize the scanning of regular paper, so as to realize the simplicity of the structure of the scanner and the flexibility of the function.

[0031] The support frame 41 and the support leg 42 in the embodiment both adopt a H-shaped cross-sectional structure, wherein the size of the H-shaped cross-section of the support frame 41 is larger than that of the support leg 42, and the opening directions of the support frame 41 and the support leg 42 are oppositely arranged. The structure design allows the support leg 42 to be completely accommodated in the support frame 41, further simplifying the appearance of the support assembly 4 and reducing the occupied space, ensuring that the support assembly 4 is in a completely accommodated state when the scanner is not used or when regular paper is scanned, so as to avoid interference with normal scanning work.

[0032] In the embodiment, the support assembly 4 further comprises a spring 43, which is installed in the H-shaped cavity of the support leg 42. Specifically, the lower end of the spring 43 is fixedly connected to the lower end of the support leg 42, and the upper end of the spring 43 is connected to the outer end of the support frame 41. The spring 43 structure design provides elastic return function, so that the support leg 42 can automatically rebound to the inside of the support frame 41 when not in use, realizing the automatic accommodation of the support assembly 4. The design simplifies the operation of the user, and enhances the compactness and neatness of the structure.

[0033] As shown in Figure 6As shown, in this embodiment, the support leg 42 has a leg plate 421, and a mounting plate 422 is provided at the bottom of the leg plate 421. The mounting plate 422 is bent inward toward the support leg 42 to form a mounting part and a limiting part. The mounting part is used to fix the lower end of the spring 43, while the limiting part is located inside the mounting part and its width is greater than the width of the mounting part. It is used to limit the range of movement of the spring 43 and prevent the spring 43 from slipping or failing. The design of the mounting plate 422 further stabilizes the installation position of the spring 43 in the support assembly 4, ensuring that the spring 43 can continuously provide a restoring force to maintain the elastic storage function of the support leg 42.

[0034] like Figure 5 As shown, the end of the support frame 41 is provided with a side plate that bends downward, and the top of the side plate is provided with a slot 411. This slot 411 is designed to allow the upper end of the spring 43 to pass through and to hook the upper end of the spring 43 onto the side plate of the support frame 41, ensuring the stable fixation of the upper end of the spring 43. Through this structure, the fixing point of the spring 43 on the support frame 41 has high stability and anti-displacement capability, thereby ensuring that the spring 43 can provide reliable elastic force, allowing the support leg 42 to be smoothly stored, and enhancing the service life and practicality of the device.

[0035] In this embodiment, the upper end of the support leg 42 is provided with an opening slot 423. The upper end of the spring 43 passes through the opening slot 423 and is hung on the side plate of the support frame 41. The design of the opening slot 423 not only facilitates the insertion and connection of the spring 43, but also ensures that the connection of the spring 43 between the support frame 41 and the support leg 42 can maintain a consistent direction and tension.

[0036] like Figure 4 As shown, in this embodiment, the bottom surface of the scanning unit 2 is designed with a mounting groove 21 for embedding the support component 4. The mounting groove 21 ensures that the support component 4 is tightly and stably connected to the bottom of the scanning unit 2, and also facilitates the storage of the support component 4 at the bottom of the scanning unit 2, so that the support component 4 is concealed when the scanner is working normally, without affecting the overall structure and operation of the scanner.

[0037] Through the structural design of the support frame 41, support leg 42 and scanning unit 2 mounting slot 21, the position arrangement of the spring 43 and the connection relationship between the spring 43 and the support frame 41 and support leg 42, the support leg 42 can be rebounded, and reasonable space is provided for each component to be thoroughly stored, so as not to affect the scanning in normal state of the scanner.

[0038] In the mounting mode of the support assembly 4, the support frame 41 can be fixed in the mounting groove 21 by bonding or screwing. The bonding mounting mode provides simple and compact fixing effect, and is suitable for use in the case of requiring compact connection in structure; and the screwing mounting mode is suitable for use in the case of requiring strong dismounting and maintenance ability, so that the support assembly 4 is more flexible during maintenance.

[0039] After a large number of angle tests, the included angle a between the bottom surface of the scanning unit 2 and the horizontal plane is 10°-14°, and preferably 12°. The angle design is realized by adjusting the support assembly 4 at the bottom of the scanner, and the front end height h of the scanner is 25mm-30mm, so that the paper enters and exits the scanner at a proper angle, thereby reducing the risk of paper jam.

[0040] The above describes the specific embodiments of the present application in combination with the drawings, but is not a limitation on the protection scope of the present application. It should be understood by those skilled in the art that various modifications or changes made on the basis of the technical scheme of the present application without creative labor are still within the protection scope of the present application.
