Description

The portable scanner structure

At present general scanner can be divided into two kinds of the bigger desktop formula of volume and portables, and both difference is except that the volume size, the difference that certain degree is also arranged in the scanning quality of integral body, trace it to its cause and be that mainly the portable scanner mostly is hand-held mode greatly, the motion scan device in zone to be scanned with its image scan, degree of stability is bad when so handing this scanner because of its user, cause the quality that scans bad and shake this portable type scanner, if will thoroughly solve the above problems, only the volume with its desktop scanner significantly dwindles, and the operator scheme of comprehensively giving up handheld scanner can meet the demand of ordinary consumer.

Place in view of foregoing problems, the purpose of this utility model is that development and Design goes out a kind of novel portable scanner, to improve consumer's usable range and wish, this scanner is by the bulky desktop formula design of tradition, implement and change portable mode into, and its paper feeding and sensitization scanister improved the form design of floating with single-point, can improve the smooth and easy of the quality of its scanning and paper feeding by this design.

And this portable scanner mainly is to be provided with together by a loam cake and the mutual spiral shell of a lower cover, and the setting of hanging down deck and high deck through the end in the lower cover, can and roll bar with its contact-type image tablet is fixed thereon, the both sides of contact-type image tablet are arranged with a paper feed plate and in addition and go out cardboard again, see through this paper feed plate and go out inductor on the cardboard and the smooth-going turnover of its paper of may command is set and reduces the paper scratch, bottom as for aforementioned contact-type image tablet then is provided with spring, so can make the contact-type image tablet be the enforcement of moving of monolateral unsteady mode, and just roll bar and can protect the mode that line contacts forever with the contact-type image tablet and resist, and help the transmission and the sensitization scanning of paper.

Advantage of the present utility model and effect are:

1. because the utility model contact-type image tablet is to adopt fixing mode to implement, only needs during scanning operation that its paper is put into automatic paper feeding scanning and get final product, so can significantly dwindle the volume of scanner, can be and carry use.

2. because the utility model scanner system adopts fixing mode and implements, therefore there is not the scanner distortion situation of the normal generation of the carry-on scanner of hand-held institute

Since contact-type image tablet of the present utility model with roll leverage and be monolateral unsteady mode and move, therefore can significantly improve the smooth and easy of the quality of its scanning and paper feeding.

4. because the utility model contact-type image tablet and roll bar and need power supply to move only, so its whole power consumption demand seldom, can directly be got final product by the computer supply, need not to install additional separately power supply device.
