Description

Technical Field

[0001] The present application relates to the technical field of archive scanners, and more specifically, to a dedicated archive OCR scanner. Background Art

[0002] The archive scanner is a device that uses photoelectric technology and digital processing technology to convert graphic or image information into digital signals by scanning. It is a kind of equipment for scanning books specially provided for archives, libraries, etc., and a new type of low-carbon and environmentally friendly document scanner. It applies the optical principle matrix CCD technology point-to-point scanning imaging principle, one-time scanning, no light moving back and forth, no glare and no radiation, which greatly improves work efficiency and facilitates readers to view and use. The archive scanner is a kind of digital processing equipment professionally provided for archives. The principle is to use matrix CCD technology to convert paper archives into images and store them, which is convenient for subsequent viewing and use, and also reduces the space occupied. It is very convenient. The archive scanner usually uses matrix CCD technology to quickly identify archive documents, and then processes and stores them as an external computer device, which reduces a lot of manual time, and can also use the USB port to connect to external storage devices. The fill light device in the existing archive scanner cannot adjust the position, and the position of the fill light is easy to be inaccurate when used.

[0003] The document with the prior art publication number CN 213585925 U provides a scanner dedicated to archive rooms. The device provides fill-in lights on both sides of a support rod, so that files can be filled with light during scanning, thereby improving the success rate of scanning. A rotating block is provided, and the rotating block is threadedly connected to a movable block through a threaded knob three. When the threaded knob three is loosened, the angle of the rotating block can be adjusted. By loosening the threaded knob two, the slider is slidably connected to the slide groove, so that the position of the fill-in light can be adjusted up and down.

[0004] Although the above-mentioned prior art solution can achieve the relevant beneficial effects through the structure of the prior art, it still has the following defects: the height of the scanner cannot be adjusted when the device is in use, and it is not convenient to store after use, resulting in occupying a large space when carrying.

[0005] In view of this, we propose a dedicated scanner for archive OCR. Utility Model Content

[0029] A special scanner for archive OCR includes a placement plate 1 and a scanner body 3. The scanner body 3 includes a shell 301, a fill light array 302 and a camera 303. One side of the placement plate 1 is rotatably connected to a bracket 2. The shell 301 is rotatably connected to a side of the bracket 2 away from the placement plate 1. The angles of the bracket 2 and the placement plate 1 are adjustable. The angles of the shell 301 and the bracket 2 are adjustable. The shell 301 can be stored at one side edge of the placement plate 1. The upper surface of the placement plate 1 is rotatably connected to a plexiglass plate 4.

[0030] Reference Figure 1-Figure 5 The height of the scanner body 3 can be adjusted by adjusting the angle of the bracket 2 and the placement plate 1, and the shooting angle of the camera 303 can be adjusted by rotating and adjusting the angle of the scanner body 3 and the bracket 2, and the archival paper can be placed under the organic glass plate 4 to fix the archival paper to prevent it from falling. When storage is needed, the bracket 2 is rotated so that the bracket 2 is attached to both sides of the placement plate 1, and the shell 301 is rotated so that the shell 301 is placed on one side edge of the placement plate 1, and the overall storage can be completed.

[0031] The bracket 2 includes two support plates 201 and an axis rod 202 fixed between one end of the two support plates 201 and rotatably connected to the placement plate 1. Multiple grooves 2011 are distributed in an annular manner at both ends of the opposite sides of the support plates 201, and both ends of the shell 301 and both sides of one end of the placement plate 1 are fixedly installed with annularly distributed convex balls 3011.

[0032] Reference Figure 3-Figure 5 The multiple grooves 2011 on the left side are distributed in a ring shape with the shaft 202 as the axis, and the shaft 202 is rotatably connected to the left end of the placement plate 1. Multiple convex balls 3011 corresponding to the grooves 2011 are distributed in a ring shape with the shaft 202 as the axis on both sides of the left end of the placement plate 1, so that the convex balls 3011 at the left end cooperate with the grooves 2011 to position the rotating bracket 2 after the angle is adjusted. At the same time, the grooves 2011 distributed in a ring shape at the right end of the support plate 201 cooperate with the convex balls 3011 distributed in a ring shape at both ends of the shell 301 to position the rotating shell 301 after the angle is rotated.

[0033] A receiving groove 101 is formed on a side of the placement plate 1 away from the shaft 202 .

[0034] Reference Figure 2 and Figure 3When the rotating bracket 2 is in a coplanar state with the placement plate 1 , the side of the scanner body 3 with the camera 303 and the fill light array 302 can be placed in the storage groove 101 to complete the storage of the scanner body 3 .

[0035] A T-shaped shaft 304 is fixedly installed at one end of the housing 301 , and a spring 203 is fixedly installed between the T-shaped shaft 304 and the support plate 201 .

[0036] Reference Figure 4 and Figure 5 Under the elastic rebound effect of the spring 203, the friction between the shell 301 and the inner wall of the support plate 201 can be increased, thereby improving the positioning strength between the shell 301 and the support plate 201.

[0037] The organic glass plate 4 is an anti-reflective organic glass plate.

[0038] The anti-reflective organic glass plate can avoid the problem of missing text caused by the reflection of the organic glass plate 4 when scanning the file text.

[0039] Working principle: multiple grooves 2011 on the left side are distributed in a ring shape with the shaft 202 as the axis, and the shaft 202 is rotatably connected to the left end of the placement plate 1. Multiple convex balls 3011 corresponding to the grooves 2011 are distributed in a ring shape with the shaft 202 as the axis on both sides of the left end of the placement plate 1. The convex balls 3011 at the left end cooperate with the grooves 2011 to position the rotating bracket 2 after angle adjustment. At the same time, the grooves 2011 distributed in a ring shape at the right end of the support plate 201 cooperate with the convex balls 3011 distributed in a ring shape at both ends of the shell 301 to position the rotating shell 301 after the rotation angle. When storing, the support plate 201 is rotated and the scanner body 3 is then inserted into the storage slot 101.
