Abstract

A technical problem solved by the technology of the utility model is to provide a paper feeding device of a portable scanner. A paper needing to be scanned is put between a portable scanner rolling wheel and a rubber rolling wheel which is arranged on a paper feeding roller, and when the scanner is moved to carry out scanning, a rubber rolling wheel on a base rolls on a flat plate, and the paper linearly moves to enter a scanning area under the action of friction between the two rolling wheels. The inclination and deformation problem of an image scanned by the portable scanner is solved, the scanning process is more stable, and complete information of the image can be kept after the image is scanned. Moreover, the paper feeding device and the portable scanner can be separated freely and are simple to assemble, small in size and convenient to carry, and the paper feeding device requires no power supply and is low in cost, low-carbon and environment-friendly.

Description

The portable scanner paper-advance unit

Technical field

The utility model technology belongs to the image scanning process field, relates to a kind of portable scanner paper-advance unit.

Background technology

Portable scanner, volume is small and exquisite, be easy to carry, can under the situation of separating computer, use, it is to rely on the roller under being arranged on to roll at pattern that the probe of most of portable scanners obtains data, then by being fixed on the gear drive on the roller, the information of displacement is passed to the computing of scanner host-processor by modes such as gratings, deposit data is in the portable scanner RAM (random access memory) card, by reading images information after modes such as USB and the computer communication.Be to support and the mobile portable scanner by roller and the strong point during most of portable scanner scan image, because hand-hold scanning, roller can not play the straight-line guidance effect well, the image inclination distortion that portable scanner can be produced scan when scan image does not reach the effect of scanning; Though the portable scanner of present some novel automatic paper feeds of band that occur, volume is big, and the cost height needs power drives.

The utility model technology, solved the inclination and distortion of portable scanner scan image, make scanning process more stable, can scan the entire image complete information, paper-advance unit and portable scanner can freely break away from, and be simple to operate, easy to carry, paper-advance unit need not power supply, and cost is low, low-carbon environment-friendly.

Summary of the invention

The technical problem that the utility model technology solves has provided a kind of portable scanner paper-advance unit, be that paper with needs scanning is placed in the middle of the rubber roll on portable scanner roller and the paper feed roller bearing, when the motion scan instrument scans, rubber roll on the base rolls at flat board, paper straight line under the frictional force effect in the middle of two rollers moves into scanning area, solved the inclination and distortion of portable scanner scan image, make scanning process more stable, the complete information that can keep image after the scanning, and paper-advance unit and portable scanner can freely break away from, assembling is simple, volume is small and exquisite, and is easy to carry, and paper-advance unit need not power supply, cost is low, low-carbon environment-friendly.

The utility model technology mainly comprises: following, paper feed roller bearing, the seat of honour, screw; A plurality of paper feed roller bearings are installed in down respectively in seat and the seat of honour, and the seat of honour links into an integrated entity by the screw assembling with following.
