The image capturing assembly 200 is disposed on the rack 100, and the image capturing assembly 200 is mainly used for capturing the test strip 20 and a test card (not shown). Specifically, the image capturing assembly 200 includes a CCD (Charge-coupled device) camera. The CCD camera can directly convert the optical signal into an analog current signal, and the current signal is amplified and subjected to analog-to-digital conversion to realize the acquisition, storage, transmission, processing and reproduction of images. The image scanner has the advantages of small volume, light weight, low power consumption, low working voltage, impact and vibration resistance, stable performance, long service life, high sensitivity, low noise, large dynamic range, high response speed, self-scanning function, small image distortion, no residual image and the like. Of course, in other embodiments, the image capturing assembly 200 may also use other types of cameras instead of the CCD camera, as long as the test paper 20 and the detection card (not shown) can be used for image capturing.

The two side light assemblies 300 are disposed on the frame 100, and the two side light assemblies 300 are respectively disposed at two opposite sides of the image capturing assembly 200, and the side light assemblies 300 are used for providing illumination to the test paper 20.

The two side light assemblies 300 are symmetrically disposed with respect to the image capturing assembly 200, so that when the image capturing assembly 200 captures an image of the test strip 20, the two side light assemblies 300 further improve the uniformity of the illumination of the test strip 20, and further reduce the false detection rate. It is to be understood that reference herein to "symmetry" does not merely refer to absolute symmetry, but rather should allow for some tolerance, as long as a more uniform illumination of the test strip 20 is achieved.

The first channel 131 is disposed obliquely with respect to the test paper 20. For example, in this embodiment, the first channel 131 is inclined by 60 ° with respect to the width direction of the test paper 20, so when the light emitted from the first channel 131 by the first beads 320 on both sides is irradiated onto the test paper 20, the brightness of the test paper 20 can be increased, and the light on both sides is more uniform after overlapping.
