<p><P>PROBLEM TO BE SOLVED: To provide a game machine structured to operate a three-dimensional structure disposed in a center accessory by a belt driving mechanism and also structured to appropriately release the excessive stress acting on a timing belt whenever the operation is started. <P>SOLUTION: In the pachinko machine, a player can visually recognize prescribed presentation by bringing a lid body 80a close to (including contact) or separating the lid body from an accessory body 80b in the front on the screen by the operation of the belt driving mechanism 98. Since the stress acting on the timing belt 95 whenever the timing belt 95 in the resting state is started can be released, while cushioned with the elasticity, by the sliding on a sliding face 85a on the outer periphery of a driven pulley 85, such inconvenience as the relatively early impairment of the efficient operation of the belt driving mechanism 98 because of the rubber fatigue, etc. can be prevented. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
