[0038] The clamping mechanism 5 is installed on the base 1 and is used to fix and flatten the documents on the base 1. The clamping mechanism 5 includes a lifting frame 51, a lower pressing plate 52 and a first sliding rod 54. The lifting frame 51 is vertically slidably connected to the front side inside the base 1. A spring is installed between the lifting frame 51 and the inner top of the base 1. The spring is used to generate a downward pressure on the lifting frame 51. A horizontal chute is provided on the side of the lifting frame 51. The two sides of the chute are slidably connected with the lower pressing plate 52. The downward pressure generated by the spring can enable the lower pressing plate 52 to press the paper document tightly.

The lifting drive mechanism 6 includes a first support plate 61, a drive rod 62 and a pressing block 63. The first support plate 61 is fixedly connected to the base 1. The middle of the drive rod 62 is installed on the first support plate 61 through a shaft. A rectangular groove for accommodating the vertical plate 2 is provided on the front side of the base 1. A pressing block 63 is vertically slidably installed in the rectangular groove. One end of the drive rod 62 is connected to the lower end of the pressing block 63, and the other end of the drive rod 62 is connected to the lifting frame 51. When the vertical plate 2 is unfolded for use, the lifting drive mechanism 6 can control the clamping mechanism 5 to move downward to press the paper document tightly. When the vertical plate 2 is folded and stored, the lifting drive mechanism 6 can drive the clamping mechanism 5 to move upward, facilitating the taking out of the paper document and the putting in of the next document.

[0040] The flattening drive mechanism 7 is installed in the base 1 and is used to control the clamping mechanism 5 to flatten the document by folding the vertical plate 2; the flattening drive mechanism 7 includes a toggle rod 71, a second support plate 72 and a drive bar 73.

The drive bar 73 is slidably connected to the second support plate 72. There is a linear groove on the drive bar 73, and the second sliding rod 74 connected to the toggle rod 71 is slidably connected in the linear groove. A return spring 76 is connected between the ends of the two toggle rods 71. A push block 75 for pushing the drive bar 73 to slide is connected to the rotating shaft of the vertical plate 2; during the unfolding process of the vertical plate 2, the flattening drive mechanism 7 can drive the two lower pressing plates 52 to move away from each other, so as to realize the combing and flattening process of the paper document.

[0041] The cleaning mechanism 8 is installed in the vertical plate 2 and is used to wipe and clean the camera 4, and the cleaning process is automatically carried out each time the vertical plate 2 is unfolded; the cleaning mechanism 8 includes a telescopic rod 81, a cleaning plate 82 and a cleaning cloth 83. The telescopic rod 81 is slidably connected in a hole provided inside the vertical plate 2. There is a spring in the hole for pushing the telescopic rod 81 to move upward. The cleaning plate 82 is installed at the upper end of the telescopic rod 81. The cleaning cloth 83 is installed on the cleaning plate 82. A pull rope 84 is connected to the cleaning plate 82, and the other end of the pull rope 84 is connected to the drive bar 73. The moving stroke of the cleaning plate 82 passes through the position of the camera 4 in the retracted state. A detachable cover plate 85 is provided on the vertical plate 2. After long - term use, the cover plate 85 can be opened to remove the cleaning cloth 83 for cleaning or replacement; each time the vertical plate 2 is unfolded, the cleaning mechanism 8 can realize the wiping and cleaning of the lens of the camera 4.

[0042] The locking mechanism 9 is installed at the front side position of the base 1 and is used to lock the vertical plate 2 in the folded and stored state; the locking mechanism 9 includes a lock catch 91, a toggle block 92 and a lock hole 93. The lock catch 91 is horizontally slidably installed at the side position of a rectangular groove on the base 1.

A lock hole 93 corresponding to the lock catch 91 is provided on the side of the vertical plate 2; when the vertical plate 2 is folded and stored, the lock catch 91 is engaged in the lock hole 93 to realize the locking of the vertical plate 2, and the locking can be released by toggling the toggle block 92.

[0043] The working process of the present invention is as follows:

[0044] When the device needs to be used to display paper documents, first place the paper document in the middle position of the concave structure of the base 1, turn the shift block 92, the shift block 92 drives the lock buckle 91 to disengage from the lock hole 93, and rotate the vertical plate 2 upward until the vertical plate 2 is in a vertical state; in this process, the vertical plate 2 is disengaged from the pressure block 63, and the lifting frame 51 moves downward under the action of the spring force, and the lifting frame 51 drives the lower pressure plate 52 to move downward synchronously, so that the lower pressure plate 52 is pressed to the surface of the paper document.

[0045] The rotation of the vertical plate 2 drives the push blocks 75 at both ends of its rotating shaft to rotate synchronously. After the push blocks 75 come into contact with the driving bar 73, they push the driving bar 73, so that the driving bar 73 slides on the second support plate 72, and the two second sliding rods 74 slide away from each other in the groove of the driving bar 73, thereby driving the two second support plates 72 to rotate. The second support plates 72 drive the two lower pressure plates 52 to slide away from each other, thereby realizing the combing and flattening of paper documents.

[0046] During the sliding of the driving bar 73, the driving bar 73 pulls the cleaning plate 82 downward through the pull rope 84, so that the cleaning cloth 83 on the cleaning plate 82 passes through the lens surface of the camera 4. Every time the device is turned on for use, the camera 4 is automatically cleaned; then the shooting board 3 is unfolded so that the camera 4 on the shooting board 3 faces the paper document, so that its content can be displayed.

[0047] When use is over, the shooting plate 3 is folded first, and then the vertical plate 2 is folded. During the folding process of the vertical plate 2, the vertical plate 2 presses down the pressure block 63, so that the driving rod 62 rotates, and the driving rod 62 drives the lifting frame 51 to move upward, so that the lower pressure plate 52 is separated from the surface of the paper document. The two lower pressure plates 52 are reset and slid close to each other under the action of the reset tension spring 76, which is convenient for taking out the paper document and putting it in next time; the telescopic rod 81 pushes the cleaning plate 82 to reset under the action of the spring, and the lock buckle 91 enters the lock hole 93 on the side of the vertical plate 2 to lock it, thereby realizing the folding and storage of the device.
