Embodiment 1
[0026] This embodiment provides a scanning pen device with adjustable font size for photographing, such as figure 1 , 2 As shown, it includes a scanning pen main body 1, a camera 2 is provided in the middle of the lower end of the scanning pen main body 1, and an MCU is arranged inside it; the scanning pen main body 1 also includes a font size adjustment command input module and a current output control module, Both the font size adjustment command input module and the current output control module are connected to the MCU; both sides of the lower end of the scanning pen body are provided with baffles 3, and the baffles 3 on both sides pass through the rotating structures on both sides respectively. It is connected to both sides of the lower end of the scanning pen main body 1, and can rotate around the rotating structure toward and away from the camera 2; inside the baffles 3 on both sides are provided with electromagnets, and the electromagnets are electrically connected in...
Embodiment 2
[0038] This embodiment provides a method for using the scanning pen device with adjustable font size described in Embodiment 1. The specific process is as follows:
[0039] In the MCU, the baffles on both sides can be rotated away from the camera at the same time in different positions to set the current size parameters required for the angle setting, and the baffles on both sides can be rotated in the direction close to the camera at the same time in different positions. Set the current size parameter required by the angle;
[0040] The user judges whether it is necessary to increase or reduce the font size of the shooting according to the font size of the reading material to be scanned, and if necessary, input an instruction to increase or reduce the shooting font size to the MCU through the font adjustment size instruction input module:
[0041] If it is necessary to increase the shooting font, after the MCU receives the instruction, according to the position of the baffle ...
