Embodiment
Below in conjunction with drawings and Examples the utility model is further elaborated:
As Fig. 1 is The general frame of the present utility model, and a kind of device of distinguishing a plurality of bar codes comprises two or two above bar code reading heads, main control board, mechanical fixed part, PORT COM, LCD display, camera, acousto-optic indicating device and target detection modules.Described bar code reading head, PORT COM, LCD display, camera, acousto-optic indicating device and target detection module are connected with main control board respectively.Fig. 2 is that the bar code carrier pushes the work synoptic diagram in the horizontal sliding mode, described two or two above bar code reading heads are installed in the mechanical fixed part 2 with the mechanical connection manner of activity, therefore the planimetric position of two or two above bar code reading heads, highly, angle is all adjustable, so that described two or two above bar code reading heads can the optimum position, distance and angle distinguish bar code separately, thereby avoided reading again and the problem of skip.Described acousto-optic indicating device comprises pilot lamp 5 and microphone device (not shown).The effect of described microphone device and pilot lamp 5 is whether the described bar code reading head of prompting is carrying out bar code reading and whether distinguishing success.Described LCD display 1 and pilot lamp 5 are installed in the outside surface of mechanical fixed part 2.When lighting source was sightless ultraviolet light of human eye or infrared light, the optical image that described LCD display 1 will camera obtains under the irradiation of ultraviolet light or infrared light displayed.The preceding bottom of described mechanical fixed part 2 offers a groove 6 that is entered described bar code reading head recognition visual field and described target detection module detection scene for bar code carrier 4 with the horizontal sliding of A direction.A kind of Unit Installation mode of distinguishing a plurality of bar codes can be Table top type or wall-hanging.For Table top type, bar code carrier 4 is pushed into described bar code reading head recognition visual field in the horizontal sliding mode and target detection module detection viewing field is in the groove 6 of mechanical fixed part 2.A plurality of bar codes 3 on the bar code carrier 4 both can be bar codes, also can be two-dimensional bar codes.
