The darkroom 100 is fixed in the cavity of the case 400, and forms a dark space with the matching object stage 200, so that the detection device can conveniently detect the sample to be detected on the object stage 200. The object stage 200 is used for carrying a sample to be tested, is connected with the darkroom 100 and can move relative to the chassis 400, and at least a part of the object stage 200 can move out of the cavity from the opening, so as to perform a sample feeding operation or a sample discharging operation. The door 300 is connected to the cabinet 400 to be rotatable with respect to the cabinet 400 to open or close the opening, and a rolling portion 310 is provided at a portion of the door 300 contacting the stage 200 when the stage 200 moves. The rolling part 310 may reduce a frictional force between the stage 200 and the door 300, thereby achieving smooth movement of the stage 200 and reducing noise during movement.

Specifically, the chassis 400 of the embodiment includes the front panel 410, and when the detection device is used normally, the front panel 410 faces the operator, so that the opening of the detection device and the bin gate 300 are disposed on the front panel 410, which is convenient for the operator to perform sampling operation or sample discharging operation.
