PROBLEM TO BE SOLVED: To easily check whether or not the variation of identification picture patterns on a variable display device is proper without reducing a play direction effect. SOLUTION: On the assumption of display with 80 dots in the varying direction of the variable display part, in the case of high speed variation for varying picture patterns for 3 dots during 4 ms, one picture pattern is varied for 80 dots ÷ 3 dots μ 4 ms = about 107 ms. In the case of medium/high speed variation, one picture is varied for 160 ms. In the case of medium speed variation, one picture is varied for 10.320 ms and in the case of low speed variation, one picture is varied for 0.640 ms. The peak speed of picture pattern variation is 0.107 sec/picture pattern. Therefore, a person in charge of check can visually confirm respective pictures successively displayed during the picture pattern variation. Further, at the peak variation speed of about 0.1 sec/picture pattern, it can be made sufficiently different from the lower variation speed and the interest of play is not reduced. |
