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

The portable scanner paper-advance unit

Technical field

The technology of the present invention 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 in the situation that 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 exchange of displacement being crossed the mode such as grating and is passed to the computing of scanner host-processor, deposit data is in the portable scanner RAM (random access memory) card, by reading images information behind the modes such as USB and the computer communication.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; Although the portable scanner of some novel automatic paper feeds of band that occur at present, volume is large, and cost is high, needs power drives.

The technology of the present invention has solved the inclination and distortion of portable scanner scan image, makes scanning process more stable, can scan whole 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 technology of the present invention solves has provided a kind of portable scanner paper-advance unit, 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 traveling priority under the frictional force effect in the middle of two rollers enters 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 technology of the present invention mainly comprises: lower, paper feed roller bearing, the seat of honour, screw; A plurality of paper feed roller bearings are installed in respectively in lower and the seat of honour, and the seat of honour and lower are integral by the screw assembly connection.

Described lower its feature is mainly: lower upper plane has the strong point to be used to support portable scanner, and the space on the strong point and upper plane makes paper that the space of turnover be arranged; The roller bearing groove of lower seat is used for placing stiff shaft, and stiff shaft can move up and down in the roller bearing groove and can rotate along Pivot Point Center; The thickness of lower seat is less than the rubber roll diameter, and the rubber roll on the paper feed roller bearing places plane and lower plane centre position, and rubber roll passes the roller bearing port, and rubber roll exposes plane and lower plane; The roller bearing buckle moves up and down the rigidity axle and does not break away from the roller bearing groove in the roller bearing groove; The cooperation of roller bearing positioning and stiff shaft location notch is placed the rigidity axle is not moved axially in the roller bearing groove; Lower seat buckle cooperates placement with seat of honour draw-in groove, with screw the seat of honour and lower is linked and packed by screw hole and screw.

Described paper feed roller bearing is an assembly, and a stiff shaft is arranged on the paper feed roller bearing, and an end of axle is provided with rigidity axle location notch, and the rubber roll of concentric is arranged on the stiff shaft, and stiff shaft and rubber roll are relatively-stationary.

Its feature of the described seat of honour is mainly: upper seat frame is that a rectangular frame can be placed and relative fixed portable position of scanner; There are paper feed port and exit slot that paper can be passed through on the seat of honour; Roller bearing groove and roller bearing notch can be placed the paper feed roller bearing, and rigidity axle location notch and roller bearing positioning cooperate to place makes rigidity axle axial location.
