Amendment September 25, 1982 The scope of claims for utility model registration is amended as follows.

[Claims for Utility Model Registration] In an automatic position display device that displays an image of the track of a moving object on a display that scans the display screen by horizontal scanning and vertical scanning, the moving object is obtained based on the measurement results of a navigation device. a line data memory that stores a signal indicating the navigation position of the vehicle as latitude and longitude data; a display control circuit that supplies track data to a display circuit based on the latitude and longitude data read from the line data memory; and the display circuit. An automatic position display device comprising: a memory flash circuit to which track display data and character pattern data of a moving object are supplied and stored, and refresh the display device.

Claims (1)

[Scope of utility model registration request] Navigation equipment is mounted on a mobile body at sea or land and outputs a signal based on its own position, and the signal from this navigation equipment is converted into latitude and longitude by taking in the necessary data from memory, compass, etc. (if latitude and longitude conversion is not performed) or coordinate conversion,
A data processing section that determines the deviation of incoming radio waves and converts it into position data, and a latitude and longitude line that is frequency-divided by the oscillation circuit's frequency divider circuit and applied to the cathode ray tube in synchronization with the horizontal and vertical synchronization signals of the CRT display circuit. means for obtaining a signal; a display control circuit provided between the data processing section and the CRT display circuit that takes in data from a map memory and supplies it to the CRT display circuit together with the position data; , a character/pattern generation circuit that stores patterns of lines, etc. and generates a combination pattern that can be displayed on a cathode ray tube based on the position data of the CRT display circuit and map data, and the display control circuit. An automatic position display device comprising means for extracting circle or line data from a generating circuit, making the signal of the position pattern correspond to the data, determining a dangerous state of the moving object, and issuing a warning.
