<p>PURPOSE:To prevent alteration, and to discover alteration easily and accurately by forming patterns of the same line pattern in the area of the same line by magnetic ink and dummy ink in each area of a lot-drawing information recording area and making the patterns among each area differ. CONSTITUTION:The lot drawing information recording area 12 of areas 12A-12F in (n) lines and (m) rows such as two lines and three rows is formed to one surface of a mount 11 forming a lottery ticket body. Patterns 14 are formed into the area 12 by line pattern while unit lot-drawing information such as numerics of one to six is shaped, and the upper section of the area 12 is covered with a transparent sheet 16 and unit lot-drawing information sections are covered with a concealing layer 17, which can be scraped off. The pattern 14 is constituted in such a manner that a fixed number of lines are formed at specific pitches by combining magnetic ink and dummy ink at every area 12A-12F and the line patterns are formed. The line patterns are shaped so as not to be made the same among the areas 12A-12F mutually.</p> |
