<p><P>PROBLEM TO BE SOLVED: To provide a game machine capable of surely stopping a presentation device in a predetermined position. <P>SOLUTION: A Yakumono (accessory) 802 is rotatably and pivotally supported on a leading end of an arm 810 having one end pivotally supported on a base member 801, and a guide shaft 821 provided in the Yakumono 802 is fitted and inserted into a guide groove 820 formed in the base member 801. When the arm 810 is rotated clockwise to make the Yakumono 802 reach a receding position A, the guide shaft 821 ascends on a second inclined plane 831 of a second guide portion 820b so as to reduce a rotation speed of the arm 810. Additionally, when the Yakumono 802 reaches a first position A' of a first guide portion 820a, reverse movement is inhibited by having the guide shaft 821 guided to a first inclined plane 830 as a rising slope even if the arm 810 bounces from a stopper piece 824 by a resilient force generated in the case where the arm 810 abuts on the stopper piece 824. Thus, the Yakumono 802 is kept in the receding position A. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
