PROBLEM TO BE SOLVED: To avoid the radio transmission interference even in a field by providing a memory unit for storing output timing set values of the display control signal in a display terminal device of a passenger guide system, and providing a setting device for changing the setting of the output timing set value of the memory unit. SOLUTION: A memory unit 16 is provided in each display terminal device 1 of this passenger guide device 7. Output timing set values for setting the output timing of the display control signal of the display terminal device 1 are stored in the memory unit 16 inside of the display terminal device 1. A setting device 14 changes the setting of the output timing set value of the memory unit 16 so as to restrict the high frequency to be leaked from the display terminal device 1 to a frequency within a range, which does not give the bad influence to the train radio transmission equipment. With this structure, basic frequency easy to be a noise source can be finely displaced so as to avoid the radio transmission interference while maintaining the operation of a circuit.
