Efficient and stable scanner

Abstract

The invention discloses an efficient and stable scanner which comprises a fed paper separation device, a scanning device and a drive motor. The fed paper separation device comprises upper fed paper separation wheels and lower fed paper separation wheels. The upper fed paper separation wheels are arranged horizontally and evenly, and upper transmission wheels are fixed in the axial direction of the upper fed paper separation wheels. The upper transmission wheels are connected through a chain. The lower fed paper separation wheels are arranged below the upper fed paper separation wheels horizontally and evenly. The radius of the lower fed paper separation wheels is smaller than that of the upper fed paper separation wheels. Lower transmission wheels are fixed in the axial direction of the lower fed paper separation wheels. The lower transmission wheels are connected through a chain. The scanning device comprises a scanning table, a scanning plate and a photosensitive sensor. The drive motor and one lower transmission wheel are fixed. The lower transmission wheel fixedly connected with the drive motor is connected with the upper transmission wheel corresponding to the lower transmission wheel through a transmission chain. Paper files to be scanned can be separated and scanned one by one. The scanner has the advantages of being simple in structure, stable in work, high in reliability and high in separation and scanning efficiency, lowering consumption of manpower resources, improving work efficiency and the like.

Description

technical field [0001] The invention belongs to the field of scanning equipment, and in particular relates to a stable scanner capable of efficiently separating documents to be scanned and scanning one by one. Background technique [0002] A scanner is a computer input device that uses photoelectric technology and digital processing technology to convert graphics or image information into digital signals in a scanning manner. The scanner has a good scanning effect on text pages and drawings, which can be scanned and input into text and image processing software, eliminating the trouble of retyping, and can modify images very conveniently. Therefore, scanners are widely used in offices. [0003] In the existing office, when scanning paper documents, they usually scan one by one; turn on the scanner, put the first one in for scanning, take out the first one after scanning, and put the second one in to scan, and so on. Once the scanning volume is large, the required scan...

AI Technical Summary

Problems solved by technology

Once the scanning volume is large, the required scanning time will be longer, and the manpower time will be correspondingly longer, which will reduce the office efficiency.

Moreover, the existing scanning structure is relatively complicated, and usually includes more driving components; once a certain driving component fails and cannot be replaced and repaired in time, it will seriously affect the working efficiency of the scanner.
