Description

Barcode scanning module and POS machine

Technical field

The utility model belongs to POS machine field, more specifically, be related to a kind of barcode scanning module and use the barcode scanning module POS machine.

Background technology

The Chinese of POS (point of sales terminal) means " point of sale " that full name is point of sale information management System, has cash or amount cashier's function of bartering.Thus current trade company mostly can be propped up using POS machine come the consumption to client Pay clearing.With the dynamic two-dimension code generated in the programs such as scanning Alipay, wechat, bank and Unionpay, to carry out consumption and payment Use it is more and more, correspondingly the use of barcode scanning module is also more and more.Current barcode scanning module generally comprises camera, passes through Camera scans the two-dimensional code, to obtain 2 D code information.Taken the photograph when directly being scanned using camera, it is necessary to entirely fall in Quick Response Code As the image pickup scope of head, cause to need to adjust when using Quick Response Code to the distance of camera, it is inconvenient to use.Asked to solve this Topic, current barcode scanning module set positioning box, and camera is installed on to the bottom of positioning box, and the top surface setting in positioning box regards Window, to limit the distance between camera and form, so that when by Quick Response Code close to form, you can taken the photograph so that Quick Response Code is fallen into It is easy to use to improve barcode scanning speed as the image pickup scope of head.Yet with the Quick Response Code on the equipment Program such as smart mobile phone Area it is larger, it is necessary to make that there is larger distance between camera and Quick Response Code, this is just needed between form and camera It is in larger distance, cause the thickness of barcode scanning template larger.

Utility model content

It is thick to solve barcode scanning module existing in the prior art the purpose of this utility model is to provide a kind of barcode scanning module Spend the problem of larger.

To achieve the above object, the technical solution adopted in the utility model is：A kind of barcode scanning module is provided, including for sweeping The camera of Quick Response Code is retouched, the supporting case for supporting the camera is further included, form, the barcode scanning is offered on the supporting case Module further includes the reflective mirror for the light at the form to be reflexed to the camera, and the reflective mirror is installed on described In supporting case, the camera is arranged on the side of the reflective mirror.

Further, the scope that the camera scanning is covered on the reflective mirror is more than reflective penetrate and is taken the photograph described in As head reflects the scope of the form corresponding region.

Further, the central axes of the camera and the angular range of the reflective mirror are 30-70 degree.

Further, further include for the headlamp to being illuminated in the supporting case.

Further, the supporting case includes supporting the light shield of the camera and is respectively arranged at the opposite of the light shield The baffle of both sides, the reflective mirror regard between the bottom of two baffles, the top surface of two baffles described in formation Window.

Further, the top surface inclination of each baffle is set in its bottom surface, and each baffle is close to the camera The width of one end is more than the width of its other end.

Further, the light shield is in horn-like that the camera is installed on the osculum end of the light shield, the light shield Big opening end is connected with the baffle.

Further, each baffle is light guide plate.

Further, the support base for supporting the reflective mirror is further included, the support base is connected with the supporting case.

The beneficial effect of barcode scanning module provided by the utility model is：Compared with prior art, the utility model is set Reflective mirror, and camera is arranged on to the side of reflective mirror, the light at form is reflexed to by camera by reflective mirror, is passed through Adjust the distance between camera and reflective mirror, you can, then will shooting to adjust the scope of camera intake form corresponding region Head is changed into the distance between camera and reflective mirror side the vertical range that needs between form, so as to by the thickness of supporting case Degree sets relatively thin and then barcode scanning module making is relatively thin.

The another object of the utility model is to provide a kind of POS machine, including barcode scanning module as described above.

The POS machine of the utility model has used above-mentioned barcode scanning module, then can be relatively thin by POS machine thickness setting, with side Portable belt, while used easy to barcode scanning.
