PROBLEM TO BE SOLVED: To provide a passenger reverse entrance preventive device for a passenger conveyor capable of preventing the reverse entrance of a passenger without deteriorating appearance by holding a getting-on/off port in a wide space without using a gate or an opening/closing door. SOLUTION: The passenger conveyor carries the passenger in one direction to its step 2 by infinitely circularly moving a plurality of steps 2 between the getting-on/off ports 3. A three-dimensional picture device 13 is arranged in a machine room 9 under the floor of the getting-on/off port 3. A three-dimensional picture for prohibiting the reverse entrance by which the passenger tries to get on from the reverse direction of the moving direction of the step 2 in its getting-on/off port 3 is formed in a space part of the getting-on/off port 3 by the three-dimensional picture device 13, and the reverse entrance of the passenger is prevented based on its three-dimensional picture.
