Description

Technical Field

[0001] This utility model relates to the field of archival digitization technology, and in particular to an archival digitization scanner. Background Technology

[0002] Archives refer to original records of various forms that have preservation value, which are directly formed by people in various social activities. Common types include electronic archives and paper archives. When conducting statistical analysis of archival information, it is sometimes necessary to scan the contents of paper archives to form electronic archives, which are convenient for storage and quick transmission, and also facilitate later viewing.

[0003] A search revealed that utility model patent CN222215797U discloses a data entry device for digital management of archives, relating to the field of archive digitization. The device includes a workbench and a placement assembly. The document to be scanned is placed in a placement slot and fixed by a pressure plate. Scanning is then performed using a scanner. Because the placement table is circular and has multiple placement slots, these slots can be rotated to be positioned below the scanner. Furthermore, the multiple placement slots allow scanning and document replacement to be performed simultaneously, saving time and improving efficiency.

[0004] Although the above-mentioned device can realize continuous input of archival paper, when completing the input of the current archival paper and changing the archival paper, it is necessary to first rotate the pressure plate, and take out the current archival paper while keeping the pressure plate in the state, and then put the archival paper back in and reset the pressure plate. The operation is too cumbersome. One hand needs to keep the pressure plate in the state, and the other hand needs to take out the current archival paper and put in the new archival paper. It is not convenient in actual use.

[0005] Therefore, it is necessary to invent a document digitization scanner to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a digital document scanner that eliminates the need to manually flip up the transparent pressure plate after the document paper arrives at the loading / unloading station. This allows for the use of the left hand to remove the old document paper and the right hand to place the new document paper, reducing the difficulty of use and further improving scanning efficiency. This solves the problem mentioned in the background art, where when completing the input of the current document paper and changing the document paper, it is necessary to first rotate the pressure plate, remove the current document paper while maintaining the pressure plate state, then reinsert the document paper and reset the pressure plate. This operation is too cumbersome, requiring one hand to maintain the pressure plate state while the other hand removes the current document paper and inserts the new document paper, which is inconvenient in actual use.

[0007] According to one aspect of this disclosure, a technical solution is provided as follows: a document digitizer scanner, comprising:

[0008] An archive paper moving mechanism is used to move the archive paper sequentially through the loading / unloading station and the scanning station.

[0009] A positioning scanning mechanism, wherein the positioning scanning mechanism is used to scan and input archival papers located at the scanning station; and

[0010] An active leveling mechanism includes an arc-shaped limiting plate and four evenly distributed flattening components. The arc-shaped limiting plate is fixedly mounted on the front of the fixing frame. Inclined guide portions are fixedly mounted at both ends of the arc-shaped limiting plate. Each set of flattening components includes a rotating shaft that is rotatably nested inside an adjacent receiving groove via a bearing. A transparent pressure plate is fixedly sleeved on the middle of the outer side of the rotating shaft. Torsion springs are sleeved on both ends of the outer side of the rotating shaft. Each torsion spring is fixedly connected between the transparent pressure plate and the inner wall of the adjacent receiving groove. A pressure block is fixedly mounted on the middle of the end of the transparent pressure plate near the arc-shaped limiting plate.

[0011] According to at least one embodiment of the document digitization scanner of the present disclosure, the document paper moving mechanism includes a base, a column fixedly disposed through the center of the top of the base, and a bearing plate rotatably sleeved on the outside of the column via a bearing.

[0012] According to at least one embodiment of the document digitizer of this disclosure, the top of the carrier tray is provided with four placement slots evenly distributed, and each of the placement slots has a receiving slot on one side near the column. A positioning magnet A is fixedly disposed through the end of the placement slot away from the column.

[0013] According to at least one embodiment of the document digitizer of this disclosure, the positioning scanning mechanism includes a mounting frame fixedly disposed on the back of the base, and a scanning camera fixedly disposed on the top of the mounting frame.

[0014] According to at least one embodiment of the document digitizer of this disclosure, a positioning magnet B is fixedly disposed on the bottom inner side of the mounting frame, the positioning magnet B being located directly below an adjacent positioning magnet A and magnetically attracted to the adjacent positioning magnet A.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] This utility model incorporates an active leveling mechanism. When the carrier tray, via the placement slot, drives any flattening component to the paper loading / unloading station, and the pressure block is positioned below the two inclined guide sections, the arc-shaped limiting plate does not restrict or obstruct the pressure block. The torsion spring drives the transparent pressure plate to remain in an inclined state around the rotation axis. At this point, the left hand removes the current document from the placement slot, and the right hand places the new document into the placement slot. Then, the carrier tray is rotated. As the carrier tray rotates, it drives the flattening component towards the scanning station via the placement slot. During this process, the... The adjacent inclined guide part blocks and guides the pressure block in the flattening assembly, thereby causing it to drive the transparent pressure plate to rotate around the arc-shaped limiting plate as the axis until it presses on the top of the document paper to flatten it. At this time, the pressure block moves to the bottom of the arc-shaped limiting plate, and the arc-shaped limiting plate continues to limit it during its movement. Compared with the prior art, this utility model does not require manually flipping up the transparent pressure plate after the document paper arrives at the paper loading and unloading station. Therefore, the operation of taking the old document paper with the left hand and putting the new document paper with the right hand can be adopted, which reduces the difficulty of use and further improves the scanning efficiency.

[0025] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawings is flipped, a component described as “below” or “under” other components or features would subsequently be positioned “above” said other components or features. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.

[0026] Figure 1 This is a schematic diagram of the overall structure of a document digitizer according to one embodiment of the present disclosure.

[0027] Figure 2 This is a schematic diagram of the paper moving mechanism 1 and the positioning scanning mechanism 2 of an archival digitizing scanner according to one embodiment of the present disclosure.

[0028] Figure 3 This is a schematic diagram of the active leveling mechanism 3 of an archival digitizer according to one embodiment of the present disclosure.

[0029] like Figures 1-3 As shown, the document digitization scanner disclosed herein may include components such as: document paper moving mechanism 1, positioning scanning mechanism 2, and active leveling mechanism 3.

[0030] like Figure 2 As shown in this disclosure, the document paper moving mechanism 1 includes a base 11, a column 12 is fixedly and through the center of the top of the base 11, a bearing plate 13 is rotatably sleeved on the outside of the column 12 via a bearing, four placement slots 14 are evenly opened on the top of the bearing plate 13, and a receiving slot 15 is opened on both sides of any one of the placement slots 14 near the column 12, and a positioning magnet A16 is fixedly and through the end of the placement slot 14 away from the column 12.

[0031] This allows the archival paper to be placed inside the placement slot 14 located at the paper loading / unloading station. Then, the carrier plate 13 is rotated, causing the carrier plate 13 to rotate around the column 12 as the axis. At this time, the placement slot 14 moves the archival paper from the paper loading / unloading station to the scanning station. During this process, whenever a placement slot 14 passes the paper loading / unloading station, archival paper can be placed into the placement slot 14. If there is already scanned archival paper in the placement slot 14, the archival paper is removed and a new archival paper is placed, thereby improving scanning efficiency.

[0032] like Figure 2 As shown, in a preferred embodiment, the positioning scanning mechanism 2 includes a fixed frame 21 fixedly disposed on the back of the base 11. A scanning camera 22 is fixedly disposed on the top of the fixed frame 21, and a positioning magnet B23 is fixedly disposed on the bottom inner side of the fixed frame 21. The positioning magnet B23 is located directly below the adjacent positioning magnet A16 and is magnetically attracted to the adjacent positioning magnet A16.

[0033] Therefore, when the carrier disk 13 rotates, it drives the positioning magnet A16 to rotate synchronously. When the positioning magnet A16 moves directly above the positioning magnet B23, the positioning magnet B23 attracts the positioning magnet A16, thereby positioning the carrier disk 13. At this time, the placement slot 14 adjacent to the positioning magnet B23 is located at the scanning station directly above the positioning magnet B23 to ensure accurate input of document paper.

[0034] It should also be noted that the positioning magnet B23 is a publicly available solution in the prior art and can be purchased directly from the market. Therefore, this application will not elaborate on its specific structure and model.

[0035] like Figure 3 As shown in this disclosure, the active leveling mechanism 3 includes an arc-shaped limiting plate 31 and four sets of evenly distributed flattening components. The arc-shaped limiting plate 31 is fixedly installed on the front of the fixing frame 21. Inclined guide portions 32 are fixedly installed at both ends of the arc-shaped limiting plate 31. Each set of flattening components includes a rotating shaft 33 that is rotatably nested inside the adjacent receiving groove 15 via a bearing. A transparent pressure plate 34 is fixedly sleeved on the middle of the outer side of the rotating shaft 33. Torsion springs 35 are sleeved on both ends of the outer side of the rotating shaft 33. Each torsion spring 35 is fixedly connected between the transparent pressure plate 34 and the inner wall of the adjacent receiving groove 15. A pressure block 36 is fixedly installed on the middle of the end of the transparent pressure plate 34 near the arc-shaped limiting plate 31.

[0036] Therefore, when the carrier tray 13 drives any flattening component to the paper loading / unloading station via the placement slot 14, and the pressure block 36 is located below the two inclined guides 32, the arc-shaped limiting plate 31 does not limit or block the pressure block 36. The torsion spring 35 drives the transparent pressure plate 34 to remain in an inclined state around the rotation axis 33. At this time, the left hand removes the current document paper from the inside of the placement slot 14, and then the right hand places the new document paper into the inside of the placement slot 14. Then, the carrier tray 13 is rotated. When the carrier tray 13 rotates, it drives the flattening component to move towards the scanning station via the placement slot 14. During this process... The adjacent inclined guide 32 blocks and guides the pressure block 36 in the flattening assembly, thereby causing the transparent pressure plate 34 to rotate around the arc-shaped limiting plate 31 as the axis until it presses on the top of the document paper to flatten it. At this time, the pressure block 36 moves to the bottom of the arc-shaped limiting plate 31, and the arc-shaped limiting plate 31 continues to limit it during its movement. Compared with the prior art, it is not necessary to manually flip up the transparent pressure plate 34 after the document paper arrives at the paper loading and unloading station. Therefore, the operation of taking the old document paper with the left hand and putting the new document paper with the right hand can be adopted, which reduces the difficulty of use and further improves the scanning efficiency.

[0037] It should also be noted that any content not described in detail in this specification is prior art known to those skilled in the art.

[0038] Those skilled in the art should understand that the above embodiments are merely for illustrating the present disclosure and are not intended to limit the scope of the disclosure. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of the present disclosure.
