DISCLOSED IS A METHOD AND AN APPARATUS FOR AUTOMATICALLY SUPPLYING A PATTERN SIGNAL IN A VIDEO DISPLAY DEVICE CAPABLE OF AUTOMATICALLY SUPPLYING SIGNALS NECESSARY FOR TESTING AND ADJUSTING A SCREEN STATE OF A PRODUCT SUCH AS A CATHODE RAY TUBE (CRT) ASSEMBLY. WHEN A PALLETTE (100) STOPS AT A CERTAIN WORKING POSITION, THE PALLETTE IS PUSHED TO THE DIRECTION VERTICAL TO A TRANSPORTING DIRECTION OF A CONVEYOR BELT (101) AND TOWARD THE OPERATOR AND THEN FIXED. AFTERWARDS, DUE TO THE OPERATION OF A CYLINDER (107A), CONNECTING RODS (66, 66A) AND A PATTERN SIGNAL SUPPLY TERMINAL (63) ARE CONNECTED TO A CONNECTOR (109) WHICH IS ELECTRICALLY CONNECTED TO THE CRT ASSEMBLY, AND THEREBY THE PATTERN SIGNAL FOR TESTING AND ADJUSTING THE SCREEN IS SUPPLIED. THE MOBILLITY IN EVERY DIRECTION GENERATED IN MOVING THE CONNECTING RODS BY THE OPERATION OF THE CYLINDER IS PROPERLY CONTROLLED BY AN ELASTIC ELEMENT. IN ADDITION, BY BUFFFERING THE RAPID RECTILINEAR MOVEMENT OF A PISTON ROD (107B) CAUSED BY THE OPERATION OF THE CYLINDER, THE PATTERN SIGNAL SUPPLY TERMINAL IS SMOOTHLY CONNECTED TO THE CONNECTOR.
