Claims

[Scope of utility model registration request]

A traveling direction detecting means detects the traveling direction of the vehicle and outputs a signal according to the traveling direction, and a horizontal deflection signal and a vertical deflection signal are respectively generated by a horizontal synchronization signal and a vertical synchronization signal obtained from the video signal of the map. outputting means, and controlling the horizontal deflection signal and the vertical deflection signal in response to the output of the traveling direction detecting means, and applying them to the deflecting means of the cathode ray tube so that the image of the map in the traveling direction of the automobile is always on the top on the cathode ray tube. A map display device comprising means for displaying a map.
