2) The passenger has a smaller walking range when passing through the security check machine, and is more suitable for the old and the weak;
3) The time for passing the security check is correspondingly shorter.
Fig. 6 is a schematic flow chart of a passenger passing a security check. According to the legend positioned at the upper left corner, a passenger firstly places the luggage in a space of 1/4 disc surface formed by 4 partition boards at the lower right corner of a rotary disc of the rotary security inspection device, and the passenger himself carries out personal security inspection through the right security inspection door.
