SEARCHING DISPLAY DEVICE WITH SCALE

摘要

PURPOSE:To enable distance to be read in details by forming distance scale lines of plural broken lines as well as to enable the distance of intended searching information to be easily read by changing the colors of the scale lines in displaying distances. CONSTITUTION:The output of a variable frequency dividing circuit 2 is applied to even and odd distance signal generating circuits 36 and 37. These circuits generate differentiated outputs at every fixed even times and odd times of searching information. These differentiated outputs control a change-over circuit 9 via an OR gate 38 so that the searching (distance) scale is displayed in a color cathode ray tube. A rough distance signal generating circuit 40 generates the signal for changing the display color of a certain distance scale line which is a rough scale.
