Problems solved by technology

[0004] Another existing test method is to use software to control the opening or closing function of the scanner, but this method must write the software opening and closing time, and the test machine must also write different software bits separately, so it is quite time-consuming

[0021] figure 1 It is a flow chart of an embodiment of the test method for a scanner of the present invention. figure 2 It is a schematic diagram of the relative positions of the scanner, the transparent projection sheet and the light source according to the first embodiment of the present invention. refer to figure 1 and figure 2 , an embodiment of the present invention provides a test method for a scanner, including the following steps. Step S1 : Print the barcode BC on the transparent transparencies 1 . In this embodiment, the step of printing the barcode BC on the transparent transparencies 1 is realized while maintaining the original size and original resolution of the barcodes BC, that is to say, the barcodes BC can be faithfully presented on the transparencies 1 without being affected by different resolutions or sizes of other display devices. Step S2: Set the transparent projection sheet 1 between the scanner 3 and the light source 2, and the direction of the li...

[0025] image 3 It is a schematic diagram of the relative positions of the scanner, the transparent projection sheet and the light source according to the second embodiment of the present invention. Compare figure 2 and image 3 , this embodiment is similar to the first embodiment, the difference is that the transparent projection sheet 1 and the light source 2 in the first embodiment are two separate elements (such as figure 2 shown), and the transparent projection sheet 1 in this embodiment is attached on the light source 2 (such as image 3 shown). More precisely, the light source 2 of this embodiment is produced by a light source device 20, such as image 3 shown. The light source device 20 may be a mobile phone screen, an LED screen, or a projector and the like. The transparent projection sheet 1 of this embodiment is pasted on the light source device 20 .

[0026] The various changes of the light source adjustment method in this embodiment are similar to those i...

Abstract

The invention discloses a test method for a scanner. The test method comprises the following steps: printing a bar code for scanner test on a transparent projection film; arranging the transparent projection sheet between the scanner and the light source; adjusting the light source; the scanner starts a scanning function according to the adjustment of the light source; scanning and decoding the bar code on the transparent projection sheet through the scanner, and outputting a scanning result to generate a test result. Therefore, according to the test method for the scanner, provided by the invention, machine verification is conveniently and effectively carried out in a manner of more conforming to a real user situation, and the tolerance of the electromechanical wheel disc and the paper ina severe environment is eliminated.

Description

technical field [0001] The invention relates to a testing method, in particular to a testing method for a scanner. Background technique [0002] On the production line of scanner product testing, the existing test method is an electromechanical roulette, which mounts a paper barcode, uses the motor to rotate to drive the barcode to move, and allows the scanner to interpret the movement of the object under test, and then starts the decoding of the scanner Function. However, its disadvantage is that the motor and paper are not well resistant to high and low temperature and high humidity, which is not conducive to testing in harsh environments. [0003] Another existing test method is to set the scanner to auto-on and auto-off modes, but this method turns off the function of the software to identify the object under test, which is inconsistent with the real user situation. [0004] Another existing test method is to use software to control the opening or closing function of t...
