PROBLEM TO BE SOLVED: To provide a diagram with characters that is hardly decrypted, easily generates and reproduces many kinds of character strings, and easily stores and records selected elements and their order.SOLUTION: A sufficient number of frames 3 for preparing many kinds of character strings are prepared and characters are filled therein randomly. To make it possible for a person preparing character strings to assume a figure and a diagram that the person can distinguish a position on a display surface by a name, a shape, and position relation such as an operation panel and a diagram that is usually used for other purposes, to arrange the frame 3 so that the position of the frame can be distinguished by the name, shape, and position relation in the figure and diagram to prepare the diagram 2 with characters, and to select the frame according to an arbitrary rule that a user can memorize easily, so that random character strings can be generated and reproduced.SELECTED DRAWING: Figure 1 |
