跡記録装置。[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 first readout device that reads out the current screen storage device in synchronization with the scanning of the display device and supplies the read current screen information to the display device as a display signal. and a past screen comprising a plurality of storage circuits that simultaneously store the digital signal from the AD converter as past screen information for one screen of the display at regular intervals without erasing the previous storage state. A storage device and a plurality of storage circuits are read out in parallel in synchronization with the scanning of the display, and the read past screen information is synthesized or one of them is switched and outputted to the display. a second reading means for supplying a display signal different from the display signal based on the current screen information; and repeating sequentially erasing one of the memory circuits for each memory circuit at intervals considerably longer than the predetermined time. A track recording device comprising erasing means.
