Description

File information digitalized recording auxiliary device

Technical Field

The invention belongs to the technical field of scanning equipment, and particularly relates to an archive information digitalized input auxiliary device.

Background

Through informatization input, the paper file can be converted into an electronic file, and digital storage and management of the file are realized. Therefore, the archive information can be conveniently and rapidly searched and found, and the efficiency and the accuracy of archive management are improved. And paper files occupy a large amount of physical space, while electronic files require relatively little storage space. Informationized entry may help institutions save archival storage space and reduce associated storage costs. Common scanners for entering files are flatbed scanners and document feed scanners. Flatbed scanners are adapted to scan individual documents or photographs, with a user placing the document on a glass plate and then covering the scanner with a cover for scanning. Document feed scanners are suitable for batch scanning of large numbers of documents, and a user may place multiple documents into an automated feeder at a time, which may be automatically scanned one by the scanner.

If the paper file is not properly protected and handled during storage, such as by moisture, heat, pressure, etc., the paper tends to buckle, deform or fold. Incorrect storage may include improper stacking, humid environments, bending of the paper due to prolonged pressure, etc. Also, during the processing and transfer of documents, if not properly handled, such as by snagging, folding or bending the sheets, the sheets may be folded, wrinkled or edge-turned. For a document feeding scanner, when a paper is wrinkled, warped or folded, a scanning head cannot scan a clear image, so that the problem of incomplete data input information is caused.

With this arrangement, during paper feeding, the archival paper passes through the first paper feeding roller 5, then passes through the paper correcting mechanism 9, and finally is fed out by the second paper feeding roller 6.

When the paper passes through the first paper feeding roller 5 and the paper correcting mechanism 9 and does not reach the second paper feeding roller 6, the paper correcting mechanism 9 is tightly attached to the paper, then the paper correcting mechanism 9 and the paper are driven to move in the same direction through the movement of the self-driven sliding plate 8, the moving speed is higher than that of the paper, the folding at the front end of the paper can be corrected through the arrangement, then the paper correcting mechanism 9 is stopped and reset, the front end of the paper continuously moves forwards through the second paper feeding roller 6, at the moment, the paper correcting mechanism 9 is still tightly attached to the paper, and the middle and rear parts of the paper can be continuously corrected by the paper correcting mechanism 9 in the paper advancing process. Through this setting, can solve paper fold, stick up the limit or the corner has the problem of folding paper.

The lens of the scanner 2 scans the corrected sheet. A progressive scan mode may be used for scanning. The lens of the scanner 2 is aligned to the left or right of the second paper feed roller 6 because the paper is corrected when the paper is located at both positions.

Referring to fig. 2, the recording assisting device for digitizing archive information further includes a paper shape recognition module, where the paper shape recognition module includes: a light source unit 10, a detection unit 11, a judgment unit 12;

The light source unit 10 and the detection unit 11 are both in signal connection with the judgment unit 12, the judgment unit 12 is in signal connection with the paper correcting mechanism 9, the light source unit 10 irradiates the surface of the paper with a light source, the detection unit 11 observes whether obvious reflection, shadow or light spots appear on the paper, and the judgment unit 12 judges whether the paper has foldouts or wrinkles.

In practice, a suitable light source is selected, such as a uniform and stable incandescent lamp, LED lamp or fluorescent lamp. The moderate brightness of the light source is ensured, and overexposure or insufficient brightness can not be caused. The light source is installed at a proper position so that the light can be uniformly irradiated to the surface of the paper. A reflective plate or diffuse reflective material may be used to diffuse the light to avoid creating too intense or concentrated spots. Preferably, the included angle of the detecting unit 11 can be adjusted, and the detecting result can be improved when the angle is adjusted. With this arrangement, if it is detected that the sheet does not need to be corrected, the sheet correction mechanism 9 is not required to be used for correction.

With this arrangement, there are two modes of use:

Mode one: the two first air bags 13 are filled with the same air, and when the paper is conveyed, the two first air bags 13 can also squeeze the paper, so that the paper is smoother. Of course, the second balloon 14 may also serve this function.

Mode two: the degree of compression of the paper can be adjusted, for example, the first air bag 13 and the second air bag 14 are respectively adjusted in the amount of air by two air adjusting members. When the pressing force of the first air bag 13 against the paper is large, if the pressing force of the second air bag 14 against the paper is small, and the rotation speed of the second paper feeding roller 6 is made larger than that of the first paper feeding roller 5, at this time, the advancing speed of the paper can be determined by the first paper feeding roller 5, sliding friction occurs between the second paper feeding roller 6 and the paper, so that the paper is leveled, the folding of the front end can be corrected, and the first paper feeding roller 5 and the second paper feeding roller 6 can straighten the paper, so that the leveling effect is further achieved.

Similarly, the first paper feeding roller 5 can have a similar effect, and it should be noted that the first paper feeding roller 5 is required to rotate reversely at this time, so that the folding at the rear end of the paper can be corrected.

Through this setting, this device can have two usage modes:

First, document feeding formula: the sheet moves in the sheet feeding path, and the scanner 2 scans information on the sheet through the scanning hole 16, and since the scanned position is close to the second sheet feeding roller 6, both the scanning hole 16 and the scanner 2 are located at the side.

Second, flatbed scanning: the sheet is placed on the horizontal table 15, and the scanner 2 is moved to the intermediate position by the electric slide table 1c, so that the sheet on the horizontal table 15 can be flatbed scanned.
