[0003] For example, after completing the slide staining, the fully automatic slide staining machine needs to transfer the sample slides to the slide reader for result inspection. Therefore, this process requires a sample slide conveying device that can place the empty slide box on the cache channel, drive the motor through the control circuit board to move the empty slide box to the working area, and promptly send the collected sample slides together with the slide box to the slide reader.

[0129] Preferably, if Fig.11 and 12 As shown, after the sample slide 4 is placed in the slide box 4, since there is residual cleaning liquid on the sample slide 4, a fan is required to blow air from the top of the slide box and out from the side vents 31, effectively forming a backflow, thereby accelerating the drying of the sample slide 4. At the same time, a step groove 35 is provided at the bottom of the slide box, so that the residual water droplets on the sample slide 4 enter the step groove 37, avoiding it from directly remaining in the third guide rail and other positions, effectively extending the service life of the device.

[0130] Preferably, if Fig.11 and 12As shown, in order to facilitate the smooth and unobstructed insertion of the sample glass slide 4 into the glass slide box 3, a chamfer 33 is performed around the top of the glass slide box 3, and a trumpet mouth 34 is designed.
