Abstract
The utility model provides a kind of USB electron microscope of special identification Quick Response Code.Main points of the present utility model are: comprise object lens, the housing of band frequency modulated light circle and mouth of finding a view, 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.When using it, only need by mouth mask of finding a view of the present utility model on Quick Response Code.
Description
Technical field
The utility model 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 purpose of this utility model is to provide a kind of USB electron microscope of special identification Quick Response Code.
The purpose of this utility model is achieved in that 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 utility model 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 utility model is placed on Quick Response Code.
Compared with prior art, good effect of the present utility model is: only to need the utility model 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 utility model is further illustrated below in conjunction with accompanying drawing.
Fig. 1 is longitudinal sectional view of the present utility model.
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 utility model 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 utility model need be placed on Quick Response Code.
1 is micro-photosensitive CCD, and 6 is LED light filling sources.
