Problems solved by technology

Most portable scanners use rollers and support points to support and move the portable scanner when scanning images. Due to hand-held scanning, the rollers cannot play a good role in guiding straight lines, so that the portable scanner will produce scanned images when scanning images. The image is tilted and deformed, which cannot achieve the scanning effect; although some new portable scanners with automatic paper feeding appear at present, they are large in size, high in cost, and require power to drive

Embodiment Construction

[0019] see figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 : the paper feed roller 12 is installed in the roller groove 122, the rigid shaft 31 on the paper feed roller 12 passes through the roller buckle 23 and firmly presses down, the plasticity of the roller buckle 23 Press in under deformation; the rigid shaft positioning groove 33 on the paper feed roller one 2 is stuck on the roller positioning gear one 24 and axially fixed; the rubber roller 32 on the paper feed roller one 2 passes through the roller port one 25 , moving up and down the rigid shaft 31 on the paper feed roller-2 can see that the distance between the rubber roller 32 on the paper feed roller-2 and the upper plane 28 and the lower plane 29 changes, so as to adapt to the paper of different thickness.

[0020] see figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 : The paper feed roller 2 3 is installed in the roller groove 2 18, the rigid shaft 31 on the paper feed roller 2 3 passes t...

Abstract

The technology of the invention solves the technical problem of providing a portable scanning instrument paper feeding device, which is characterized in that paper to be scanned is placed in a potion between a portable scanning instrument rolling wheel and a rubber rolling wheel arranged on a paper feeding rolling shaft, when a scanning instrument is moved for scanning, the rubber rolling wheel arranged on a base rolls on a flat plate, the paper does linear movement to enter the scanning region under the effect of the friction between the two rolling wheels, and the inclination deformation problem of images scanned by the portable scanning instrument is solved, so the scanning process is more stable, the complete information of the images can be maintained after the scanning, in addition, the paper feeding device can be freely disconnected from the portable scanning instrument, the assembly is simple, the size is small, the carrying is convenient, the paper feeding device does not need a power supply, the cost is low, and low-carbon and environment-protection effects are realized.

Description

technical field [0001] The technology of the invention belongs to the field of image scanning processing, and relates to a portable scanner paper feeding device. Background technique [0002] Portable scanners are small in size, easy to carry, and can be used without a computer. The scanning head of most portable scanners obtains data by rolling the pattern on the bottom roller, and then through the gear fixed on the roller. Transmission, the information of the moving distance is transmitted to the host processor of the scanner for calculation through grating and other means, the data is stored in the memory card of the portable scanner, and the image information is read after communicating with the computer through USB and other means. Most portable scanners use rollers and support points to support and move the portable scanner when scanning images. Due to hand-held scanning, the rollers cannot play a good role in guiding straight lines, so that the portable scanner will p...
