Abstract
PURPOSE: To enable to display various test patterns easily and quickly on the display plane, by making unnecessary the software and the operation time, through the addition of a selector switch and a simple control circuit.
CONSTITUTION: Normally, the selection switch 15 is in close condition, the control circuit 3 selects the data memorized in the memory 1 and performs gate control so that the display is made on the dispaly plane of CRT6. Next, in case of test pattern display, the circuit 3 inhibits the data display memorized on the memory 1 by selecting the switch 15 to the open condition, and gate control is made so that the test pattern code set with the set switches 7 to 14 can be dispalyed on the display plane of CRT6.
