Depiction of a time machine from Doraemon, or more specifically the one used by Doraemon himself. It appears as a flat, flying carpet-esque device with a console at the front and a lamp at the right side, though other models of the time machine have also appeared in the series.
While under time travel, the machine will enter a "time tunnel" with similar traffic and policing as an actual road and then create a portal at the entrance/exit point.
