Abstract: <P>PROBLEM TO BE SOLVED: To provide a ball extraction hole opening/closing device for easily opening/closing a shutter which clogs a ball extraction hole formed at the bottom of a tray member in a game machine.  <P>SOLUTION: When a wall surface part being a member at the side of a player in a lower tray part is pushed in the pachinko game machine, the shutter 70 is moved in a nearly depth direction (the upward direction in the figure), so as to open the hole 66a. When the wall surface part is pushed again in the depth direction from a (b) state, the shutter 70 returns from the (b) state to an (a) state, so that the hole 66a is clogged. Consequently the shutter 70 is opened/closed by pushing the wall surface part, so that an opening/closing operation is more easily performed compared with a conventional ball extraction hole opening/closing device having a lever under the lower tray part. Besides, it only has to be checked whether a member, which is larger than the conventional lever being the wall surface part (a part at the side of the player in the lower tray part), is pushed or not, so that the opening/closing of the shutter is easily recognized.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
