Description

Technical Field

[0001] The utility model relates to the technical field of scanner scanning, and more specifically, to a device for testing the depth of field of a scanner. Background Art

[0002] In different usage scenarios, the scanning effects of scanners are different. The main factors affecting the scanning performance of scanners include: scanning angle and depth of field of scanning. And the scanner processes the signal reflected back from the surface of the bar code through a photoelectric sensor for decoding and output. However, due to different resolutions of the sensors, the optimal scanning angles and depths of field of scanners of different specifications are inconsistent, and it is necessary to detect the scanner. If the distance from the bar code during installation is not within the depth of field of scanning, it will affect the code reading effect and cause missed scanning, which is likely to misjudge the performance of the scanner. Or if the scanning angle during installation is not within the optimal range, it may also affect the code reading effect, and in severe cases, it will cause code reading errors.

[0053] It should be noted that the specific structure of the Z-axis moving component 4 in the embodiments of the present utility model is not limited, as long as it can adjust the distance between the barcode scanner 6 and the test code.
