Abstract
A method and an apparatus for automatically supplying a pattern signal for testing and adjusting a screen of a video display device such as a cathode ray tube (CRT) assembly. When a pallette stops at a certain working position, the pallette is pushed to the direction vertical to a transporting direction of a conveyor belt and toward the operator and then fixed. Afterwards, due to the operation of a cylinder, connecting rods and a pattern signal supply terminal are connected to a connector which is electrically connected to the CRT assembly, and thereby the pattern signal for testing and adjusting the screen is supplied. The mobility 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 buffering the rapid rectilinear movement of a piston rod caused by the operation of the cylinder, the pattern signal supply terminal is smoothly connected to the connector for testing and adjusting the screen of the CRT assembly.
