Claims (1)

[Scope of claim for utility model registration] A first memory circuit that stores changes in the navigational position based on the measurement results of a navigation device that measures the navigational position of the own ship, and a target object obtained by transmitting and receiving detection pulses. a radar display that displays a distance marker; a distance marker generator that displays a distance marker on the radar display and simultaneously transmits distance data from the own ship to the distance marker position; and a direction marker that displays a direction marker on the radar display. an azimuth marker generator that simultaneously transmits azimuth data indicating a relative azimuth to a predetermined reference azimuth, and the distance marker and azimuth marker based on each data of the distance marker generator and the azimuth marker generator. a second memory circuit that stores the determined position information on the radar display; a display memory circuit that appropriately reads and stores the memory contents of the first memory circuit and the second memory circuit; a display device for displaying the memory contents of the memory circuit; a screen movement switch and a screen enlargement/reduction switch; moving the display state on the display device by appropriately changing the memory contents of the display memory circuit; An operation switch input section for achieving a desired state such as enlargement or reduction, and a control section for performing data processing between the navigation device, the first and second memory circuits, the display memory circuit, and the operation switch input section. A track recording device equipped with.
