ABSTRACT:
A CPU displays an image on a display device with reference to an image location table stored in advance in a RAM. When coordinates on the image are sequentially designated by an input device, the CPU sequentially compares the locations specified by the designated coordinates with those of checking points stored in the image location table. The CPU determines that the operator is authorized when errors or differences between the locations compared with each other are within an allowable range and when the order of designation of the coordinates is appropriate.
