Claims

[Claims for Utility Model Registration] An AD converter that converts a received signal from radar or sonar, etc. into a digital signal, a scanning raster display, and the display that uses the digital signal from the AD converter as current screen information. a current screen storage device that stores one screen worth of data; and a digital signal from the AD converter that stores one screen worth of the display screen at regular intervals as past screen information. past screen storage means for storing the number of times the data has been recorded so that each memory can be read out separately; and displacement amount detection means for determining the amount of displacement from a certain point in time of the mobile body equipped with the radar or sonar, etc.; a displacement recording device that stores the determined displacement amount for each predetermined period of time; and a displacement recording device that reads the current screen storage device in synchronization with the scanning of the display device, and sends the read current screen information to the display device. A first display device that supplies the displacement amount of the displacement amount detection means as a display signal and also supplies the displacement amount of the displacement amount detection means to the display device as a screen displacement signal, thereby displacing and displaying the read current screen information with respect to a reference position on the display surface.
a readout means, in synchronization with the scanning of the display device, reads out the past screen storage means by distinguishing the memory for each fixed time period, and sends the read past screen information to the display device according to the current screen information; Supplying the display signal to the display device as a display signal different from the display signal, and reading the displacement amount corresponding to the storage time point of the read past screen information from the displacement amount recording device, and supplying the displacement amount to the display device as a displacement signal. A track recording device comprising: a second readout means for supplying a signal;
