Flattening mechanism used for photographing file support

Abstract

The invention discloses a flattening mechanism used for a photographing file support. The flattening mechanism comprises a backing plate and a transparent pressing plate. The two side ends of the backing plate are respectively provided with a clamping part in a clamping mode, the top ends of both the clamping parts are provided with pivoting parts having pivoting holes, and the inner side ends of both the clamping parts are provided with clamping grooves. The two side ends of the transparent pressing plate are respectively provided with a rotating connecting part, the outer side ends of both the rotating connecting parts are provided with protrusive shafts, and the inner side ends of both the rotating connecting parts are provided with embedding grooves. Both the protrusive shafts are inserted into the corresponding pivoting holes. The pivoting parts are column stands which protrudes upwards from the top ends of the clamping parts. The pivoting holes are waist-shaped holes and formed in the column stands in a through mode in the horizontal direction. The top ends of the column stands are further provided with limiting screw holes which are formed in the column stands in a through mode in the vertical direction. The flattening mechanism further comprises threaded springs and screw plugs, wherein the threaded springs and the screw plugs are located in the limiting screw holes. The protrusive shafts of the rotating connecting parts are located on the lower portions of the waist-shaped holes. The threaded springs are pressed at the top ends of the protrusive shafts through the screw plugs. The flattening mechanism can be adaptive to files to be photographed, wherein the files are different in thickness, and the flattening mechanism is high in adaptability.

Description

technical field [0001] The invention belongs to the technical field of photographing brackets, and in particular relates to a flattening mechanism for photographable file racks. Background technique [0002] With the popularization of computers and the widespread use of the Internet, electronic office and electronic filing have become the first choice for modern file management. For banks, securities, telecommunications and other units, it is necessary to photograph or scan a large number of daily materials, files, documents, etc. to form electronic documents for archiving. [0003] In the prior art, the equipment for photographing or scanning paper documents is mainly an ordinary scanner or a high-speed camera. The advantage of ordinary document scanners is that the effect of obtaining images is good, and the printing is relatively clear. The main disadvantage is that the scanning speed is slow, and the cost of large-format scanning machines is high. There are also automat...

Problems solved by technology

The advantage of ordinary document scanners is that the effect of obtaining images is good, and the printing is relatively clear. The main disadvantage is that the scanning speed is slow, and the cost of large-format scanning machines is high. There are also automatic paper-feeding high-speed scanners on the market, but their prices are impressive It is daunting; although the shooting speed of the high-speed camera is faster than the scanning speed, it needs an external computer system, which is cumbersome to operate, and the overall shooting efficiency and imaging effect are not ideal.

[0004] At present, most of the mobile phones, Apple system and Android system tablets on the market are equipped with high-definition cameras. 8 million and 13 million pixel cameras have become the standard configuration of current mobile phones, and with the development of the times, their imaging pixels will become more and more High, the imaging effect is far superior to that of the high-speed cameras on the market, and it is close to or comparable to the imaging effect of document scanners. However, there is no stand on the market that is compatible with mobile phones and tablets and is dedicated to taking pictures and archiving documents. , and if you take a hand-held photo, the imaging effect will vary from person to person, and it is difficult to meet the imaging requirements of electronic file archiving
