Abstract

The invention provides a special USB (universal serial bus) electron microscope for identifying two-dimensional codes. The special USB electron microscope is mainly characterized by comprising an object lens with a light shield ring, a shell and a view finding opening. The outer surface of the shell is in the shape of a prism; the size of the view finding opening is proper so that each two-dimensional code can be accommodated in the view finding opening; a circular-tube-shaped lens positioning sleeve is fixed onto the wall of a cavity of the shell, the object lens with the light shield ring is fixed onto a cavity of the circular-tube-shaped lens positioning sleeve, and the distance from the object lens to the view finding opening is proper so that each two-dimensional code can completely enter a lens. The special USB electron microscope has the advantage that when the special USB electron microscope is used, only the view finding opening of the special USB electron microscope needs to cover the two-dimensional codes.

Description

The USB electron microscope of special identification Quick Response Code
Technical field
The present invention relates to a kind of USB electron microscope, specifically the USB electron microscope of special identification Quick Response Code.
Background technology
Hand-held USB electron microscope is contained in circular tube shaped housing by the object lens of band frequency modulated light circle and eyepiece, eyepiece is leading screw shape, by rotating screw, screw type eyepiece moves up and down, the distance between object lens and eyepiece is regulated namely to focus, identify the observing object varied in size, demonstrate the image of observing object on computers.In modern commerce activity, Quick Response Code application is very extensive.Use hand-held USB electron microscope identifiable design Quick Response Code, but there is much inconvenience: because the area of USB electron microscope area ratio Quick Response Code is little, need hand-held USB electron microscope that its camera lens is aimed at Quick Response Code all the time, and the distance between adjustable lens and Quick Response Code, Quick Response Code is all entered in camera lens, also will focus continually simultaneously.Start above-mentioned three actions simultaneously, cooperatively interact, and hand will be kept not shake, just can see image in 2 D code clearly, this makes troubles to user; Secondly, the shell of hand-held USB electron microscope is cylindrical, easily tumbles ground from desktop, breaks hand-held USB electron microscope.
Summary of the invention
For solving the problems of the technologies described above, the object of this invention is to provide a kind of USB electron microscope of special identification Quick Response Code.
The object of the present invention is achieved like this: it comprises object lens, the housing of band frequency modulated light circle and mouth of finding a view, and it is characterized in that: the outside surface of housing is prism; The size of mouth of finding a view is limited Quick Response Code can be included in; Tubular camera lens locating sleeve is fixed in shell body lumen wall, and the object lens of band frequency modulated light circle are fixed in the mantle cavity of tubular camera lens location, and object lens all can enter camera lens to the distance of mouth of finding a view with Quick Response Code and be as the criterion.The enlargement factor of said object lens is as the criterion can see Quick Response Code clearly.Because the present invention is exclusively used in scanning Quick Response Code, only need an enlargement factor determined to see clearly just by Quick Response Code, do not need to regulate enlargement factor, therefore eliminate eyepiece.Use time it and mouth of finding a view of the present invention is placed on Quick Response Code.
Compared with prior art, good effect of the present invention is: only to need the present invention and mouth of finding a view thereof to be placed on Quick Response Code just, do not need hand-held, very easy to use; Secondly, eliminate eyepiece, reduce cost; Finally, the outside surface of housing adopts prism, the trouble of avoid and tumble ground, causing damage.
Accompanying drawing explanation
The present invention is further illustrated below in conjunction with accompanying drawing.
Fig. 1 is longitudinal sectional view of the present invention.
Fig. 2 is the upward view of Fig. 1.
Embodiment
It comprises object lens 4, the housing 2 of band frequency modulated light circle 5 and mouth 7 of finding a view, and the outside surface of housing is prism; The size of mouth 7 of finding a view is limited Quick Response Code can be included in; Tubular camera lens locating sleeve 3 is fixed in shell body lumen wall, and the object lens of band frequency modulated light circle are fixed in the mantle cavity of tubular camera lens location, and object lens all can enter camera lens to the distance of mouth of finding a view with Quick Response Code and be as the criterion.The enlargement factor of said object lens is as the criterion can see Quick Response Code clearly.Because the present invention is exclusively used in scanning Quick Response Code, only need an enlargement factor determined to see clearly just by Quick Response Code, do not need to regulate enlargement factor, therefore eliminate eyepiece.When using it, only mouth of finding a view of the present invention need be placed on Quick Response Code.
1 is micro-photosensitive CCD, and 6 is LED light filling sources.
