Abstract
The invention discloses an adjustable two-dimensional code scanning gun. The adjustable two-dimensional code scanning gun comprises a scanning gun shell, a light source arranged in the scanning shell, an optical lens, a scanning module and an analog to digital conversion circuit, wherein the optical lens comprises a first optical lens and a second optical lens of which the focal lengths are different; the first optical lens and the second optical lens are coaxially arranged on one side of the analog to digital conversion circuit; the distance between the first optical lens and the second optical lens can be adjusted along the axis of the first optical lens. The adjustable two-dimensional code scanning gun is convenient to use, and two-dimensional codes of various sizes, appearances, diameters and densities can be handled through one scanning gun, thereby reducing the cost on purchase of various scanning guns, and promoting the informatization development of the two-dimensional codes.
Description
Technical field
The present invention relates to a kind of Quick Response Code scanner, relate in particular to a kind of adjustable Quick Response Code scanner.
Background technology
Quick Response Code scanner is a kind of to capture Quick Response Code by camera, and CPU and algorithm that the Quick Response Code utilization grabbing is carried itself carry out computing, thereby reaches the decoding instrument of decoded result.Common Quick Response Code scanner is generally made up of light source, optical lens, scanning module, analog digital conversion phone and plastic casing, it utilizes photovalve to convert the light signal detecting to electric signal, then electric signal is converted into digital data transmission by analog-digital converter in computing machine, processes.
Quick Response Code scanner in the market, is divided into two kinds of general cleer and peaceful high definitions with a series of generally because of the difference of camera focal length, to adapt to the Quick Response Code of different sizes, different densities.As longer in the camera focal length of general clear Quick Response Code scanner, be applicable to the Quick Response Code compared with distant positions to capture; The Quick Response Code scanner camera focal length of high definition is nearer, is applicable near and density also larger Quick Response Code to capture.But the camera focal length of above-mentioned existing Quick Response Code scanner is all fixed, this just limited general clear Quick Response Code scanner be applicable to reply larger diameter (as diameter be 8mmX8mm and more than), also larger Quick Response Code of density; And the Quick Response Code scanner of high definition adapts to diameter less (as 2mm-8mm), Quick Response Code that density is also less.Therefore in the time need to capturing different Quick Response Codes, need to be equipped with different Quick Response Code scanners, increase the purchase cost of enterprise.
Summary of the invention
In order to overcome above-mentioned defect, the invention provides a kind of adjustable Quick Response Code scanner, can realize as required the conversion of general cleer and peaceful high-definition function, significantly reduce enterprise procurement cost.
The present invention for the technical scheme that solves its technical matters and adopt is: a kind of adjustable Quick Response Code scanner, comprise scanner shell and be located at light source, optical lens, scanning module and the analog-to-digital conversion circuit in this scanner shell, described optical lens comprises the first optical lens and the second optical lens that focal length is different, this first optical lens and the second optical lens coaxial cable are located at a side of described analog-to-digital conversion circuit, and this first optical lens can be adjusted its distance to the second optical lens along its axis.
As preferred version of the present invention, described the first optical lens is fixed in described scanner shell by screw thread activity, on the side of this first optical lens, connect a driving lever, the outer end of this driving lever extends on described scanner shell side, on described scanner shell to being provided with movable storage tank by driving lever.
The invention has the beneficial effects as follows: this adjustable Quick Response Code scanner different the first optical lens and the second optical lenses of built-in focal length simultaneously, the Quick Response Code scanner of high definition and general clear two kinds of patterns is concentrated in a scanner, and on the first optical lens, adjustable structure is set, thereby realize the conversion of general cleer and peaceful high-definition function according to different Quick Response Codes, not only easy to use, and can just can tackle all size outward appearance diameter by a scanner, the Quick Response Code of various density, thereby reduce the cost of purchasing various scanners, promote the Informatization Development of Quick Response Code.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is decomposition texture schematic diagram of the present invention.
By reference to the accompanying drawings, make the following instructions:
1---scanner shell 2---analog-to-digital conversion circuit
3---first optical lens 4---second optical lens
5---driving lever 6---movable storage tank
Embodiment
Below in conjunction with accompanying drawing, a preferred embodiment of the present invention is elaborated.But protection scope of the present invention is not limited to following embodiment, the simple equivalence of in every case being done with the present patent application the scope of the claims and description changes and modifies, within all still belonging to patent covering scope of the present invention.
As shown in Figure 1, 2, a kind of adjustable Quick Response Code scanner, comprise scanner shell 1 and be located at light source, optical lens, scanning module and the analog-to-digital conversion circuit 2 in this scanner shell, wherein, optical lens comprises the first optical lens 3 and the second optical lens 4 that focal length is not identical, this first optical lens and the second optical lens coaxial cable are located at a side of analog-to-digital conversion circuit 2, and this first optical lens 3 can be adjusted its distance to the second optical lens 4 along its axis.
Wherein above-mentioned the first optical lens 3 can be adjusted its structure to the distance of the second optical lens 4 along its axis, be set in the present embodiment, the first optical lens 3 is fixed in scanner shell 1 by screw thread activity, on the side of this first optical lens 3, connect a driving lever 5, the outer end of this driving lever 5 extends on scanner shell 1 side, on scanner shell 1 to being provided with movable storage tank 6 by driving lever 5.In use, if need to tackle the Quick Response Code of different size or densities, only need to stir the driving lever 5 on scanner shell 1, drive the first optical lens 3 to rotate by driving lever 5, thereby the distance of adjusting these the first optical lens 3 to second optical lenses 4, finally realizes the conversion of general cleer and peaceful high-definition function.This adjustable Quick Response Code scanner is not only easy to use, and can just can tackle by a scanner Quick Response Code of all size outward appearance diameter, various density, thereby has reduced the cost of purchasing various scanners, promotes the Informatization Development of Quick Response Code.
