Reference picture 3, after scanner 4 scans the bar code with Business Name information of loading frame bottom, letter is read in output
Number into controller 3, simultaneously, it is positioned in the weight data input controller 3 of the loading frame on scale body 1, controller 3 will
The weight measured is shown by display 2.Controller 3 receives simultaneously to be read on signal and scale body 1 after weight signal, by scanning
Stored and shown in the computer 5 that the data input that Business Name information and goods weigh is connected with the signal of controller 3.When
When staff needs to check Business Name and corresponding goods weight, the input unit such as keyboard, mouse of computer 5 need to be only used
Mark obtains the data being stored in the memory of computer 5, reduces the amount of labour of staff, while improve the note of data
The accuracy and security of record.
Further, since bar code is attached to the lower end of loading frame, when loading frame is placed on scale body 1, because light is asked
Topic, scanner 4 are difficult identification bar code, so being provided with around scanner 4 for detecting whether there is loading frame to be positioned over
On scale body 1 and control the Light Control Unit of light light on and off.Light Control Unit include be arranged at the upper surface of scale body 1 be used for examine
Survey on scale body 1 and whether be placed with loading frame and export the luminance detection device of luminance detection signal, be coupled to luminance detection device
Dress is judged with the brightness for receiving luminance detection signal and judging to export light controling signal after the amplitude size of luminance detection signal
Put 6 and be coupled to brightness judgment means 6 with receive light controling signal be used for worked for scanner 4 when brightness is provided
Lamplight component 7, wherein, reference picture 1, lamplight component 7 is included in parallel or series in the LED string 14 of brightness judgment means 6.It is preferred that
, using the LED string 14 being arranged in parallel, when there is LED damages, remaining LED can also continue to illuminate.
As shown in figure 1, the brightness that luminance detection device is located at the one side of scanner 4 including being arranged at the upper surface of scale body 1 passes
Sensor 8, the light levels of the upper surface of the luminance sensor 8 detection scale body 1, and luminance detection signal is exported, the present embodiment uses
Luminance sensor 8 with detection the darker output of light signal amplitude it is bigger.Reference picture 4, brightness judgment means 6 include being used for
The reference voltage circuit 9 and comparator 10 of the reference voltage compared with luminance detection signal are exported, reference voltage circuit 9 includes electricity
Hinder R1, R2, resistance R1 one end is connected to supply voltage, the other end be connected to resistance R2 one end and comparator 10 it is anti-phase defeated
Enter end, resistance R2 other end ground connection；The in-phase input end of comparator 10 is coupled to luminance sensor 8 to receive brightness detection letter
