<p><P>PROBLEM TO BE SOLVED: To provide a game machine having a rotation-linear motion converting mechanism to be set in a smaller space than a conventional mechanism. <P>SOLUTION: In the Pachinko game machine 10, the rotation-linear motion converting mechanism 80X to linearly move a first door 51 is configured to extend a linear-motion winding belt 85 from a reel 81 by only a necessary quantity and to wind up an unnecessary part of the belt around the reel 81. With this structure, the rotation-linear motion converting mechanism can be set in smaller space than a conventional a rack and pinion rotation-linear motion converting mechanism. Further, the bulking strength of the liner-motion winding belt 85 is high because the belt is composed of a circularly curved metal plate in the cross direction in the linearly extended state. Since the linear-motion winding belt 85 is composed of the metal plate, the reliability is higher than the one composed of resin, and the belt can be thinner and compact. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
