[0029] Specifically, in this embodiment, the paper tray 1 is of A3 paper size, i.e. 297mm×420mm, and can be used to place A3, A4 and A5 paper, suitable for different paper shooting and scanning requirements; the mounting seat 2 is a rectangular structure, and the mounting seat 2 can be detachably mounted on one side of the length direction of the paper tray 1, that is, the mounting seat 2 is in contact with and connected to the wide side of one side of the paper tray 1, the length of the mounting seat 2 is the same as the width of the paper tray 1, and the thickness of the mounting seat 2 is greater than that of the paper tray 1, and the mounting seat 2 can be used as a baffle to assist in the positioning of the paper on the paper tray 1.

[0030] It is understandable that the paper tray 1 can also be designed to be the same size as A2, A1 or A0 paper according to needs to further improve its adaptability. There are no specific restrictions here and it can be selected according to actual needs.

[0031] In order to facilitate the quick disassembly and assembly of the paper tray 1 and the mounting seat 2, the paper tray 1 can be set as a metal structure, or a magnet can be installed in the paper tray 1. At the same time, a magnet can be installed in the mounting seat 2 to connect the paper tray 1 and the mounting seat 2 through magnetic adsorption.

[0041] The fill light 82 is arranged along the circumference of the frame 81 and is located above the paper tray 1. It can provide fill light from the circumference of the paper during shooting and scanning without causing projection (for example, vertical or oblique fill light may project the shadow of the vertical pole 3, horizontal pole 6, scanning device clamp 7 or scanning and shooting device 13 onto the paper), effectively improving the shooting and scanning effects.

[0042] The specific working principle is:

[0043] First, the bracket is assembled. After the assembly is completed, the scanning and photographing device 13 is installed on the scanning device fixture 7;

[0044] The paper to be scanned is placed on the paper tray 1 so that one corner of the paper is aligned with an inner corner of the frame 81 , and the position of the scanning and photographing device 13 is adjusted according to the size of the paper to perform scanning and photographing.

[0045] The position of the scanning and photographing device 13 is adjusted as follows: first loosen the first tightening knob 9, adjust the position of the slider 4 so that the slider 4 is aligned with the center line of the wide side of the paper and tighten the first tightening knob 9, then loosen the third tightening knob 11 to adjust the lateral position of the cross bar 6 so that the scanning and photographing device 13 is located directly above the center of the paper and then tighten the third tightening knob 11, and finally loosen the second tightening knob 10, adjust the height of the scanning and photographing device 13, and tighten the second tightening knob 10 until the scanning and photographing requirements are met.

[0046] It is understandable that the position of the scanning and photographing device 13 can also be other positions, or other adjustment orders, and no excessive restrictions are made here; in order to ensure the adjustment accuracy, scales can also be set on the mounting base 2, the vertical pole 3 and the horizontal rod 6.
