PURPOSE: To prevent image signal and voice signal from being interrupted by unnecessary guidance by guiding only when a predetermined plurality of data coincide and when a controller is switched manually.

CONSTITUTION: When data from a position detector 4 that outputs present rent position data coincides with data from a thicket reader 5 and a key input device and when operation is switched manually, images and voices from a recording reproducer 2 are switched as well as those from a guidance device 3. For example, passengers cast their tickets into the device 5 to set an arbitrary channel through the device 6, thereby making an image receiver 1 output images and voices from the device 2. Just before a get-off station, images and voices from the device 2 are switched to guidance from the device 3. In emergency, the crew operates a controller 7 manually to switch to guidance.
