Hand-held scanning device based on OCR identification technology

Abstract

The invention belongs to the technical field of OCR scanning equipment, and particularly relates to a handheld scanning device based on an OCR recognition technology, the handheld scanning device comprises a scanning device body, the scanning device body is symmetrically provided with a shell and a handheld part, and an air blowing mechanism is arranged in the shell; the air blowing mechanism comprises a piston cavity, a piston disc, a sector gear and an air outlet guide pipe, a springback piece is connected between the piston disc and the piston cavity, the piston disc is connected with a square rod, the square rod is connected with a spur rack, the shell is connected with a driving belt wheel, the air outlet guide pipe is communicated with the handheld part, and the spur rack is connected with a spur rack. The handheld part is hollow and is provided with a plurality of through holes; the problems that when a large number of paper characters are scanned and recognized, people hold a handheld OCR scanner from the two sides for a long time, the temperature of the handheld part is prone to rise, sweat accumulates, when other people use the scanner subsequently, the accumulated sweat makes other people feel uncomfortable, and the use experience is affected are solved.

Description

technical field [0001] The invention belongs to the technical field of OCR scanning equipment, and in particular relates to a hand-held scanning device based on OCR identification technology. Background technique [0002] Existing OCR equipment includes high-speed cameras and handheld OCR scanners. High-speed cameras are usually large in size, take up a lot of space and are not easy to carry. Therefore, in people's offices, more handheld OCR scanners will be used. The existing hand-held OCR scanners are usually bar-shaped, and a bar-shaped scanning head is installed at the bottom. The scanning head at the bottom scans and recognizes the text on paper. However, when scanning and recognizing a large amount of text on paper, people will hold the handheld OCR scanner from both sides for a long time, and it is easy to heat up the hand-held part and accumulate sweat. When others use it, the accumulated sweat will make others feel uncomfortable and affect the experience of use. ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a hand-held scanning device based on OCR recognition technology to solve the problem that people will hold the hand-held OCR scanner from both sides for a long time when performing a large amount of paper text scanning and recognition. The hand-held part heats up and accumulates sweat. When others use it later, the accumulated sweat will make others feel uncomfortable and affect the user experience.
