Description

Technical Field

[0001] The utility model belongs to the technical field of file scanners, and in particular relates to a file scanner. Background Art

[0002] An archive scanner is a type of device that uses photoelectric technology and digital processing technology to convert graphic or image information into digital signals by scanning. It has the advantages of simple operation and protection of original documents, and is widely used in archives, libraries and other places.

[0003] At present, the common file scanner mainly consists of a workbench and a scanning component. When in use, the document to be scanned is placed on the workbench, and the scanning component scans the document for graphics and images. As we all know, in real life, different documents will have differences in thickness, size, etc.

[0004] However, most of the workbenches of the existing archive scanners are arranged horizontally. Although such workbenches can effectively carry thinner documents, when the documents are thicker, the pages of the thicker documents are prone to flipping and deformation during the scanning process, which makes the accuracy of the document scanning by the archive scanner poor and the applicability of the archive scanner poor.

[0005] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to a person skilled in the art.

The scanning component is used to scan and process the data placed on the supporting workbench.

[0012] In one or more embodiments of the utility model, a pair of storage avoidance grooves are cut above the supporting workbench, and the storage avoidance grooves match the adjustable limit plate. The storage avoidance grooves are cut to facilitate the storage and limit of the adjustable limit plate. Adjustment slide grooves are cut in each of the pair of storage avoidance grooves. The adjustment slide grooves are cut to facilitate the assembly and sliding limit of the limit slider.

[0013] In one or more embodiments of the utility model, a limit slider is slidably mounted in the adjusting slide groove, and the limit slider is hinged to the lifting connecting rod. The limit slider plays the role of supporting, fixing and moving control of the lifting connecting rod.

[0014] In one or more embodiments of the utility model, one side of the limit slider is rotatably connected to an adjusting threaded rod, and the adjusting threaded rod is threadedly connected to the supporting workbench. The limit slider is moved and controlled by rotating the adjusting threaded rod, so as to facilitate the movement control of the lifting connecting rod.

[0026] like Figures 1 to 5 As shown, a file scanner in one embodiment of the utility model comprises: a scanning workbench 1, an adjustable limit assembly 2, and a pair of clamping assemblies 3.

[0027] like Figure 1 As shown, a plurality of evenly distributed supporting legs 101 are fixedly connected to the bottom of the scanning workbench 1, so that the scanning workbench 1 can be supported and fixed by the plurality of supporting legs 101.

[0028] like Figure 1 As shown, a scanning assembly 102 is fixedly mounted on one side of the scanning workbench 1. The scanning assembly 102 scans and processes the data placed on the supporting workbench 201.

[0029] like Figures 2 to 3 As shown, the adjustable limit assembly 2 is assembled on the scanning workbench 1, and the adjustable limit assembly 2 includes a supporting workbench 201, and the supporting workbench 201 is fixedly installed above the scanning workbench 1. The adjustable limit plate 202 is stored and limited by the supporting workbench 201, and at the same time, the supporting workbench 201 plays an auxiliary supporting role for the scanned data.

[0030] like Figures 2 to 4 As shown, a pair of adjustable limiting plates 202 are hinged above the supporting workbench 201. By adjusting the angle of the pair of adjustable limiting plates 202, the scanned material can be supported at multiple angles, which reduces the page flipping or scanning deformation of the scanned material during the scanning process, and improves the scanning accuracy of the scanning component 102.

[0031] like Figures 2 to 3 As shown, a pair of adjustable limit plates 202 are both hinged with a lifting link 203 below. The adjustable limit plates 202 are supported and limited by the lifting link 203. At the same time, the adjustable limit plates 202 can be adjusted and controlled in angle by controlling the movement of the lifting link 203.

[0032] Specifically, a pair of storage avoidance grooves are cut above the supporting workbench 201, and the storage avoidance grooves match the adjustable limiting plate 202. The storage and limiting of the adjustable limiting plate 202 is facilitated by cutting the storage avoidance grooves.

[0033] like Figures 2 to 3 As shown, a pair of storage avoidance grooves are both provided with adjustment slide grooves 204. By providing the adjustment slide grooves 204, it is convenient to assemble and slide the limit slider 205.

[0034] like Figures 2 to 3 As shown, a limit slider 205 is slidably mounted in the adjusting slide groove 204, and the limit slider 205 is hinged to the lifting link 203. The limit slider 205 plays the role of supporting, fixing and moving control for the lifting link 203.

[0035] like Figures 2 to 3 As shown, one side of the limit slider 205 is rotatably connected with an adjusting threaded rod 206, and the adjusting threaded rod 206 is threadedly connected to the supporting workbench 201. The limit slider 205 is moved and controlled by rotating the adjusting threaded rod 206, so as to facilitate the movement control of the lifting connecting rod 203.

[0036] like Figures 2 to 3 As shown, one end of the adjusting threaded rod 206 located outside the supporting workbench 201 is fixedly connected with an adjusting end 207. It is convenient to drive the adjusting threaded rod 206 to rotate by applying a force to the adjusting end 207.

[0037] like Figures 2 to 3 As shown, a pair of clamping assemblies 3 are symmetrically assembled above a pair of adjustable limiting plates 202, and the clamping assemblies 3 include a pair of assembly sliders 301, and a pair of assembly sliders 301 are slidably assembled above the adjustable limiting plates 202. The assembly sliders 301 play the role of assembling and limiting the page clamping plates 302.

[0038] Specifically, a pair of limiting sliding grooves are cut on the upper sides of the pair of adjustable limiting plates 202, and the limiting sliding grooves are matched with the assembly slider 301. The limiting sliding grooves play the role of assembly and sliding limiting for the assembly slider 301.

[0039] like Figures 2 to 3 As shown, a page clamping plate 302 is slidably mounted between a pair of assembly slide blocks 301. The page clamping plate 302 is convenient for clamping and limiting the scanned document.

[0040] like Figures 2 to 3 As shown, a guide slide bar 303 is fixedly mounted in the assembly slider 301, and the guide slide bar 303 is arranged through the page clamping plate 302. The page clamping plate 302 is controlled to move by the sliding cooperation between the guide slide bar 303 and the page clamping plate 302, so that the page clamping plate 302 can clamp and limit the materials with different thicknesses.

[0041] like Figures 2 to 3As shown, the outer side of the guide slide bar 303 is sleeved with a clamping spring 304, and the clamping spring 304 is arranged above the page clamping plate 302. The page clamping plate 302 is supported and limited by the contraction and reset of the clamping spring 304, which improves the stability of the page clamping plate 302 in clamping and limiting the data.

[0042] During specific use, the data to be scanned are placed on the supporting workbench 201 and the adjustable limiting plate 202 , and the data are scanned and recorded by controlling the operation of the scanning component 102 .

[0043] When the document to be scanned is thick and page flipping or scanning deformation occurs during the scanning process, the adjusting threaded rod 206 can be driven to rotate by applying a force to the adjusting end 207. The adjusting threaded rod 206 moves with the rotation under the action of the internal and external threads, and the movement of the adjusting threaded rod 206 drives the limit slider 205 to slide in the adjusting slide groove 204. During the sliding process of the limit slider 205, the lifting connecting rod 203 lifts the adjustable limit plate 202, so that the adjustable limit plate 202 can support the document to be scanned at multiple angles, thereby reducing the page flipping or scanning deformation of the scanning component 102 during the scanning process.

[0044] At the same time, the page clamping plate 302 can be slid to the clamping position according to actual conditions, and the height of the page clamping plate 302 can be adjusted by manually lifting the page clamping plate 302, and the page clamping plate 302 is moved above the page edge of the document to be scanned. Then, the page clamping plate 302 is released, and the page edge of the document to be scanned is clamped and limited by the clamping spring 304, which further improves the stability of supporting the document to be scanned and improves the accuracy of scanning the document to be scanned.
