The display decorative frame (decorative frame) 23 is provided with a flange 40 projecting to the side, and is fixed to the game board 11 with screws in a state where the flange 40 is superimposed on the front surface of the game board 11.

  Now, the gaming machine 10 of the present embodiment is provided with a winning opening 30 according to the present invention on the right side of the display decoration frame 23. The winning opening 30 is always closed by the open / close door 35 (see FIG. 7), and the result of the normal symbol success / failure determination performed when the game ball passes inside the start gate 18 shown in FIG. When this happens, the open / close door 35 falls to the side and is opened, allowing a game ball to enter. Hereinafter, the vicinity of the winning opening 30 will be described in detail.

  As shown in FIG. 2, a base portion 24 that overlaps the front surface of the game board 11 and bulges from the inner edge of the display decoration frame 23 to the lower right is formed in the lower right portion of the display decoration frame 23. The base portion 24 is provided with a winning projection 33 (corresponding to the “winning device” of the present invention) that protrudes from the front surface of the game board 11 to one game ball or more and less than two balls. 33 is provided with a winning opening 30 that opens to the right.

  As shown in FIGS. 3 and 4, the winning projection 33 has a front cover wall 34 disposed at a position away from the base portion 24, and protrudes rearward from the front cover wall 34. A guide path constituting wall 33Y constituting a guide path 28 for discharging the entered game ball to the back side of the game board 11 is provided. The guide path constituting wall 33Y extends to the left from the upper opening edge of the winning opening 30, and then extends to the left from the first forming wall 33S that curves and extends downward, and the lower opening edge of the winning opening 30. And a second component wall 33T extending downward. The lower ends of the first component wall 33S and the second component wall 33T are connected in a U-shape. As a result, the guide path 28 has a shape that extends leftward from the winning opening 30 and then extends vertically downward (see FIG. 5), and a game ball is placed at the lower end of the guide path 28 to the rear side of the game board 11. An intake port (not shown) is provided. The right end portion of the first component wall 33S is a steeply inclined portion 33U that is steeper than its left side. Moreover, the part extended in the left-right direction of the 2nd structural wall 33T is left-lowering, and has a level | step difference (refer FIG. 5). The winning opening 30 of the present embodiment has a width that allows two game balls to pass.

  Further, the winning projection 33 is provided with an outer block 36 disposed on the right side of the second component wall 33T with a gap K between the second component wall 33T and the right end of the second component wall 33T. The outer block 36 includes a first inclined surface 36A extending downward from a position separated from the right end of the second constituent wall 33T to the lower right, and a winning projection extending downward from the right end of the first inclined surface 36A. A second inclined surface 36B that forms a part of the outer edge of 33, and a communication surface 36C that connects the left ends of the first inclined surface 36A and the second inclined surface 36B.

  In the gap K described above, a metal shaft member (shaft) 35J extending from the front cover wall 34 to the rear of the base portion 24 is disposed. And the lower end part of the door 35 is fitted by this shaft member 35J, and it is comprised so that the door 35 may rotate according to rotation of the shaft member 35J.

  Specifically, as shown in FIGS. 6A and 6B, the open / close door 35 is connected to a solenoid 45 disposed behind the base portion 24 via a shaft member 35 </ b> J and a connecting portion 46. And it is urged | biased in the standing posture by the tension | pulling spring 47 (refer FIG. 6 (A)). When the solenoid 45 is energized, the urging force of the tension spring 47 is resisted, and as shown in FIG. When stopped, the tension spring 47 returns to the standing posture.

  The open / close door 35 is provided with a guide surface 35A that extends flat on the guide path 28 side, and on the opposite side, an external bulge surface 35B that is rounded and bulged outward is provided. Further, the state where the open / close door 35 is in the standing posture corresponds to the closed state of the open / close door 35 of the present invention (see FIG. 7). As shown in FIG. 7, an interval (gap) A that is equal to or more than 1/4 of the diameter of the game ball and less than the diameter is provided between the front end portion of the open / close door 35 and the steeply inclined portion 33U. The state in which the open / close door 35 is in the sideways posture corresponds to the open state of the open / close door 35 of the present invention (see FIG. 5). When the open / close door 35 is in the open state, the guide surface 35A is substantially flush with the upper surface of the right end portion of the second component wall 33T (corresponding to the “opening lower inner surface” of the present invention).

  As shown in FIG. 5, a stopper 35 </ b> S is formed at a lower portion of the shaft member 35 </ b> J in the opening / closing door 35, and the opening / closing door is brought into contact with the contact surface 36 </ b> C of the winning projection 33. 35 is positioned in the closed state, and the stopper 35S contacts the lower surface of the right end portion of the second component wall 33T, so that the open / close door 35 is positioned in the open state.

  As described above, the winning projection 33 is provided with the front cover wall 34. The front cover wall 34 covers the guide path 28 from the front at a position away from the base portion 24 by one game ball or more and less than two balls, and faces the glass window 10W with a slight gap therebetween. . Here, in the gaming machine 10 according to the present embodiment, the end portion on the winning opening 30 side of the front cover wall 34 extends upward from the vicinity of the lower opening edge of the winning opening 30, and opens and closes as it goes upward. An inclined portion 34 </ b> L is inclined toward the back side of the guide path 28 so as to be separated from the door 35. Specifically, the inclined portion 34L is inclined upward to the left from the upper right position of the shaft member 35J to the left end portion of the steeply inclined portion 33U in the first component wall 33S.

  As shown in FIG. 7, a substantially triangular space (gap) N is provided between the inclined portion 34 </ b> L, the steeply inclined portion 33 </ b> U, and the open / close door 35 in the closed state. The space N has a size of 0.5 or more game balls and less than 1 ball. With such a configuration, the game ball is not contained (pinched) between the inclined portion 34L, the steeply inclined portion 33U, and the open / close door 35 in the closed state, and the game ball is guided into the guide path. It becomes easy. Further, the end surface of the inclined portion 34L is a tapered surface B (corresponding to the “inclined surface” of the present invention) that extends toward the back side of the guide path 28 from the front to the rear (see FIGS. 4 and 9). .

  This completes the description of the configuration of the gaming machine 10 of the present embodiment. Next, the operation and effect of the gaming machine 10 of this embodiment will be described. As described above, the winning opening 30 is always closed by the open / close door 35. Then, when the result of the normal symbol success / failure determination made when the game ball passes inside the start gate 18 is a win, the open / close door 35 is tilted sideways and opened, and the game flows down the game area R1. Part of the ball enters the winning opening 30.

  By the way, in a conventional gaming machine, there is a case where a ball is clogged near a winning opening that is opened and closed by an opening / closing door. As shown in FIG. 8, this ball clogging occurs when the game ball heading toward the winning opening 1 is supported by three points of the opening / closing door 2, the glass window 3, and the front cover wall 4. It is thought that this occurs when the force is applied to the game ball in a well-balanced manner by being pressed against the front cover wall 4 by the open / close door 2 biased to the front.

  On the other hand, in the gaming machine 10 of the present embodiment, the end of the front cover wall 34 on the side of the winning opening 30 is further away from the open / close door 35 in the closed state toward the upper side (downstream side). ), The opening / closing door 35 is rotated toward the closed state while the game ball is moving toward the winning opening 30, and the game ball is moved by the opening / closing door 35 to the front cover wall 34. Even if it is pushed to the side, the game ball is moved to the back side of the guide path 28 along the inclined portion 34L without being pinched, so that the position of the ball easily collapses with the movement, and the occurrence of the ball clogging is caused. Can be prevented. Furthermore, since the end surface of the inclined portion 34L is a tapered surface B, the game ball can easily flow to the base portion 24 side, and the occurrence of ball clogging is further prevented.

  Further, it is considered that the biasing force of the tension spring 47 becomes stronger as the opening / closing door 35 is closer to the open state, and the biasing force of the tension spring 47 becomes weaker as the opening / closing door 35 is closer to the closed state. When the power is the same, it is considered that the force that the shaft member side of the open / close door 35 pushes the game ball is stronger than the force that the front end side of the open / close door 35 pushes the game ball. For this reason, when the opening / closing door 35 changes from the open state to the closed state, the opening / closing door 35 is close to the open state, and a game ball is sandwiched between the shaft member 35J side portion of the opening / closing door 35 and the front cover wall 34. In particular, the game ball is easily sandwiched between the front cover wall 34 and the open / close door 35. However, as described above, since the front cover wall 34 is provided with the inclined portion 34L, the game ball is provided with the inclined portion. It moves to the upper left along 34L and is guided to the front end side of the open / close door 35. Then, the opening / closing door 35 approaches the closed state, and the biasing force of the tension spring 47 is weakened. The force by which the opening / closing door 35 pushes the game ball toward the front cover wall 34 is weakened, the support relationship (balance) of the game ball is likely to be broken, and the game ball can easily enter the guide path 28. Further, since the end surface of the inclined portion 34L is a tapered surface B, the support relationship (balance) of the game balls is more likely to be lost, and the game balls are more likely to flow down to the guide path 28.
