FIG. 8 is a diagram for explaining the configuration in the winning opening (big winning opening) of the big winning device in this embodiment and the movement path of the game balls in the big winning opening.
As shown in FIG. 8, the guide chamber 30 includes an inner wall surface 30a facing the back surface 42a of the open / close door 16b in a closed state, and the inner wall surface 30a is centered from a lateral end 31a into which a game ball enters. It has an inclined surface 32 in which the distance (width) from the opening / closing door 16b (that is, the distance from the big prize opening 16) gradually increases toward the side (the side end 31b side where the big prize opening detection switch 16a is provided). Yes.
Further, the open / close door 16b is formed such that the width from the lower edge 40 gradually decreases from the lateral end 31a in the region facing the inclined surface 32 on the back surface 42a toward the center side (the big prize opening detection switch 16a side). A stepped portion (projecting stepped portion) 44 is provided.
The protruding stepped portion 44 has an inclined side 44a that is inclined from the upper end edge 41 side to the lower end edge 40 side when the open / close door 16b is closed by setting the width from the lower end edge 40 in this way. .

As described above, the gaming machine of the present embodiment performs so-called right-handed hitting a game ball aiming at the right side of the game area during the jackpot game.
Therefore, when the opening / closing door 16b is opened as shown in FIG. 8A, the game ball falls to the right end edge 43 side of the back surface 42 of the opening / closing door 16b and proceeds on the back surface 42a of the opening / closing door 16b from the right side to the left side. It reaches the big prize opening detection switch 16a.
There are mainly the following two paths for the passing paths of the game balls in the big winning device of this embodiment shown in FIG.
In the first route A, which is the main route, the game ball X dropped on the back surface 42a of the open / close door 16b on the right end edge 43 side is along the formation direction of the inclined piece 44a of the right protruding step portion 44 (guide). This is a path that travels on the back surface 42a of the open / close door 16b and reaches the inside of the guide chamber 30. That is, the inclined piece 44a of the protruding stepped portion 44 acts as a guide portion where the stepped surface from the open / close door 16b guides the game ball. The game ball X then travels in the guidance chamber 30 to the left in the figure and follows a path C that leads to the big prize opening detection switch 16a.
There are game balls that enter the induction chamber 30 from the left protruding step 44 by, for example, bouncing on the open / close door 16b, but are rare and differ from the gist of the present embodiment. do not do.

In the second route B, which is a sub route, a part of the game balls Y that have fallen on the right end edge 43 of the back surface 42a of the open / close door 16b ride on the protruding step portion 44 without reaching the inclined piece 44a side, and the guidance chamber 30 This is a route that enters the induction chamber 30 from the right end portion 31a side and proceeds to the special winning opening detection switch 16a side. Thereafter, the game ball Y joins the path C and reaches the special winning opening detection switch 16a.
In the second path, the inclined surface 32 provided in the guide chamber 30 of the large winning device of the present embodiment exhibits a characteristic effect.
That is, the game ball Y flows along the inclined surface 32 in the second path, but there is only one game ball that can move on the protruding step portion 44 along the inclined surface 32 at the same time. That is, a guide path 80 for a game ball is formed by the inclined surface 32 and the protruding step portion 44. Due to the presence of the guide passage 80, a flow of the game ball Y whose traveling direction is regulated is generated in the second path B (assuming that two or more are provided between the inclined step surface 32 on the protruding step portion 44). Even if the game ball is about to flow, the game ball farther from the inclined surface 32 falls from the protruding step portion 44 and only follows the path A). As shown in FIG. 10, the game ball does not stay in the right end portion of the induction chamber.

The game ball Y, whose travel direction is regulated by the route B and whose travel direction is adjusted, comes into contact with the game ball X entering the guide chamber 30 from the route A when joining the route C, and the game ball X Is pushed out to the big prize opening switch 16a side.
Thereby, the generation | occurrence | production of the ball | bowl clog in a guidance chamber can be prevented effectively, without the game ball from the path | route A staying in the vicinity of the confluence | merging position of the path | route A and the path | route C. FIG.
In addition, by arranging the inclined side 44a to be inclined (indicator-shaped when viewed from the upper edge 41), the number of game balls flowing from the right edge 43 to the first path A is increased and the door 16b is opened. Can regulate the flow (movement direction) of the game ball. Thereby, the first path A can flow more game balls in preference to the second path B, and can prevent the game balls from staying and clogging in the winning device. .
Although FIG. 8A shows a state where the opening / closing door 16b is opened, even when the opening / closing door 16b is closed and inclined, the same operation as in FIG. 8A is performed.

Further, as shown in FIG. 8B, even when the open / close door 16 is closed with the game ball left on the open / close door 16b, the inclined surface 32 and the protruding stepped portion 44 are in the closed state. In the guide chamber 30, a guide passage 80 for guiding the game ball from one lateral end portion 31a to the other lateral end portion 31b is formed.
As in the case of FIG. 8A, the guide passage 80 has a width that allows only one game ball to pass.
Therefore, even a game ball that has fallen into the induction chamber 30 from the path A when the open / close door 16b is closed contacts with the game ball Y flowing from the path B, so However, it is possible to move toward the entrance detection sensor 16a without inconvenience such as clogging of the game balls due to mutual interference.
Further, the shape of the protruding stepped portion 44 is that of a rail that guides a game ball dropped on the open / close door 16b to the inner bottom surface 30b side of the guide chamber 30 when the open / close door 16b is in the state as shown in FIG. Acts as follows. Therefore, the game ball in the guide passage 80 can be smoothly guided.

FIG. 9 is a top view for explaining the configuration of the back side of the inner wall surface of the opening in the large winning device of the present embodiment.
As shown in FIG. 9, the inner wall surface 30 a of the guide chamber 30 of the prize winning device 100 is the inclined surface 32 as described above from the side of the lateral end portion 31 a, so that there is an empty space on the back side of the inclined surface 32. It is secured.
Therefore, in the big prize winning device 100 of the gaming machine of the present embodiment, the big prize opening solenoid 16c can be installed on the back side of the guidance chamber 30 without greatly increasing the thickness toward the depth side.
Conventionally, in order to keep the thickness of the big prize device 100 thin, it has been necessary to provide a solenoid below or on the side of the induction chamber 30, and the size of the big prize device itself has been increased. However, in the present embodiment, it is possible to reduce the size of the overall prize winning device 100 as a whole as shown in FIG.
