The control chip of mainboard control fitting extends the purpose of PDA functions to reach.
As a kind of form in above-mentioned extension, Quick Response Code identification technology as developing faster automatic identification skill now
Art, obtains wide in terms of ecommerce, retail, chain, list, safe and secret, tracking, license, stock taking, data redundant
General application, is adapted to numerous industries such as mobile sale, hospital, logistics, storage, harbour.But existing PDA is by external list
Camera carries out Quick Response Code capture, and its accuracy of identification and recognition speed are all not ideal enough, and generally also needs to utilize extra solution
Analysis software or hardware are assisted in identifying, and the control core for the peripheral hardware accessory that the hardware components of these auxiliary are set on PDA
Piece on mainboard inside PDA with needing while the aesthetic property of cabling inside extra wiring, influence PDA using also very inconvenient.
Utility model content
The technical problem that the utility model is solved is to provide a kind of Quick Response Code reading code PDA, to solve above-mentioned background skill
Shortcoming in art.
The technical problem that the utility model is solved is realized using following technical scheme：
Image-forming assembly, the image-forming assembly are provided with a kind of Quick Response Code reading code PDA, including PDA bodies, the PDA bodies
For dual camera mechanism, including the camera and imaging lens being independently arranged, camera and imaging lens rear portion pass through independence
CAN connection sampling unit, and the sampling unit includes two groups of data-interfaces, and equal at two groups of data-interface rear portions
An independent change-over circuit is connected with, and is connected successively between the corresponding change-over circuit of the data-interface of connection camera
Scanner frame by frame and spot sampling's amplifying device are connected to, two change-over circuit rear portions connect comparing unit, and in comparing unit
Rear portion is connected to the central processing unit in PDA.
In the utility model, light compensating apparatus is also included in the CCD camera assembly, the light compensating apparatus is light-emitting diodes
Pipe, is arranged at by imaging lens rostral, and be symmetrical arranged with camera relative to imaging lens.
