It is emitted back towards photodetector 320 and causes result error in judgement, it is ensured that accuracy of reading.Second separator 440 and test
Noncontact between bar 200 and form the second light-transmitting gap, the light reflected from detection zone 202 and clear area 204
Line can enter photodetector 320 via the second light-transmitting gap and be detected, thus above-mentioned photoelectric detection system 10 energy
Enough effectively preventing light from disturbing, the accuracy of testing result significantly improves.
Each technical characteristic of embodiment described above can combine arbitrarily, for making description succinct, the most right
The all possible combination of each technical characteristic in above-described embodiment is all described, but, if these skills
There is not contradiction in the combination of art feature, is all considered to be the scope that this specification is recorded.
Embodiment described above only have expressed the several embodiments of the present invention, and it describes more concrete and detailed,
But can not therefore be construed as limiting the scope of the patent.It should be pointed out that, for this area
For those of ordinary skill, without departing from the inventive concept of the premise, it is also possible to make some deformation and change
Entering, these broadly fall into protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be with appended power
Profit requires to be as the criterion.
