SCANNING MECHANISM AND SECURITY CHECK DEVICE HAVING THE SCANNING MECHANISM

摘要

A scanning mechanism (100) comprising a millimeter wave transmitting/receiving antenna module (10) for scanning a to-be-imaged object in a predetermined scanning area (S). The millimeter wave transmitting/receiving antenna module (10) comprises a millimeter wave transmitting/receiving antenna unit (11). A signal terminal of the millimeter wave transmitting/receiving antenna unit (11) faces towards the predetermined scanning area (S). And the scanning mechanism (100) further comprises a dustproof film (20) covering the signal terminal. Also disclosed is a security check device having the scanning mechanism. The signal terminal of the millimeter wave transmitting/receiving antenna unit (11) is sealed and isolated by providing a dustproof film (20) on the millimeter wave transmitting/receiving antenna module (10). With a simple structure, the security check device is easy and convenient for repair and maintenance, with lower cost. When the millimeter wave transmitting/receiving antenna unit (11) emits and receives millimeter waves, the millimeter waves do not need to pass through a plexiglass, instead, it passes through a dustproof film (20), with little attenuation for the millimeter wave signal, and improving the three-dimensional imaging effect of the security check device.
