<p><P>PROBLEM TO BE SOLVED: To provide pachinko balls of which the origin is surely judged to solve many problems such as unauthorized use in playing such as bringing-in of balls from other shops and modification of the balls, use for crimes in which the balls are fit into bombs or the like and the illegal abandonment of used balls. <P>SOLUTION: Letters, graphic forms, symbols or the like for specifying a user's name by emitting a laser beam are stamped on the surface of the pachinko ball 1. A two-dimensional code or a bar-code is stamped by emitting the laser beam onto the surface of the pachinko ball 1. The pachinko balls are stamped with a marking apparatus which is composed of a laser irradiating device for performing the marking of the user's name or the like on the pachinko ball and a transporting/standing-still means by which the pachinko balls are transported to a laser beam irradiating position where the pachinko balls are irradiated by a laser beam from a laser beam irradiating device and also the pachinko balls are brought to a standstill in the laser beam irradiating position for a certain term. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
