Abstract

PURPOSE:To use extracted part from a raster for a distance scale of a detected image by displaying a marker so that the parts to be extracted from the raster may be positioned every specific distance. CONSTITUTION:A marker signal generator 10 emits a marker signal to display the marker on a CRT display unit 5. A control circuit 11 turns change-over switches 4, 8, 9 to the marker sides after an ultrasonic pulse is transmitted by a transmitter 2. At this time, the change time of the change-over switches 4, 8, 9 is set so that the displayed distance on the CRT display unit 5 may be provided every specific distance that is previously fixed.
