The invention discloses a biochip detector. The biochip detector is characterized in that a shell body and an image displaying mechanism are included; a light source mechanism, a biochip loading mechanism and an image capturing mechanism are arranged in the shell body, the light source mechanism is arranged under the biochip loading mechanism, the image capturing mechanism is arranged over the biochip loading mechanism, and the image capturing mechanism is electrically connected with the image displaying mechanism. The biochip detector has the advantages that a biochip is loaded by the biochip loading mechanism, a light source is supplied to the biochip through the light source mechanism, and then the image capturing mechanism captures image information in the biochip and transmits the captured image information to the image displaying mechanism; the structure is simple, the portability is good, and a more accurate observation result can be obtained.
