Abstract
PURPOSE:To make it possible to display detection information of a fish detector etc., which have a long repeat period, with pictures on the Braun tube unit by using a buffer memory and main memory to convert the information period. CONSTITUTION:After detection information signals of ultrasonic distance measuring unit 1 are temporarily written in buffer memory unit 5, write information of memory 5 is read and written in main memory unit 6 in a prescribed order required for picture display after one detection completion, and contents of memory 6 are read in a prescribed order at a prescribed repeat period from the completion of this write to the next detection start (rewrite of memory 5) so that the contents above may be equal to the recorded image on the recording paper in a recorder, and they are displayed on the fluorescent face of Braun tube 10. Then, the operation above is repeated. As a result, detection information of ultrasonic distance mesuring unit 1 having a long repeat period is converted to information having a short repeat period suitable for picture display, so that pictures can be displayed on Braun tube 10.
