(However, the number of prize ball signals derived by the other prize ball detectors 51, 52, 55a, 55b, 56a, 56b, 62a, 62b is a relatively large number, for example, 13 or 15. On the other hand, the prize ball number signal based on the starting ball detector 60 is a relatively small number, for example, 5 or 7). This is because the wiring from the starting ball detector 60 is directly connected to the main board 120. By doing so, it is easy to find out whether or not wiring (called a hanging substrate or the like) incorporating an incorrect circuit board is connected in the middle thereof. The wiring that directly connects the starting ball detector 60 and the main board 120 has a color that is clearly different from the colors of other wirings (in the case of the present embodiment, pink and yellow fluorescent colors). From this point, it is easy to determine whether or not the wiring from the starting ball detector 60 has been tampered with. Further, since the wiring connecting the starting ball detector 60 and the main board 120 can be viewed from the back side of the gaming machine, fraud can be more easily found.

Embodiment (C) is a third embodiment.
[0051]
The ball game machine 1 according to the present embodiment is provided in a game area 41 of a game board 40, and as a predetermined condition, a combination of symbols when the variable display device 44 stops changing is a predetermined combination of big hit symbols (for example, With the occurrence of a specific game state (for example, a big hit) based on the establishment of the symbol of (1) in one of the hit lines, a first state (for example, an opening / closing plate 49 described later) which is advantageous to the player wins An open state in which the game ball 80 can be received in the area 73) and a second state disadvantageous to the player (for example, a closed state in which the open / close plate 49 described below cannot receive the game ball 80 in the winning area 73). A special variable winning ball device 48 is provided. The special variable prize ball device 48 includes a prize area 73 behind an opening / closing plate 49 provided in front of an opening 72 formed in the mounting board 70. The prize area 73 includes a V prize area (not shown) and 10 A count winning area (not shown) is provided. In the big hit state, when the game ball 80 wins in the V winning area provided in the winning area 73, the continuation right of the big hit state is established up to a predetermined number of times. That is, the prize area 73 provided in the special variable prize ball device 48 includes a V prize area and a 10-count prize area, and the upper limit of the predetermined number (for example, 15 times) when the game ball 80 wins in the specific prize area. It is possible to continue the game in the big hit state.
[0052]
In the winning area 73 of the special variable winning ball device 48, there is provided a movable inclined member (seesaw) 77 that enables winning in the specific winning area and other winning areas without adjusting the nail. Is provided with a ball rebound portion 78 that rebounds a game ball 80 that rolls upward against a downward inclination.
[0053]
As shown in FIG. 5, the special variable prize ball device 48 is attached to the game board 40 by an attachment board 70. The mounting board 70 has an opening 72 for receiving a game ball 80 flowing down the game area 41. Then, the opening 72 is opened and closed by an opening / closing member (opening / closing plate 49) that rotates in the front-rear direction about a rotation shaft 76 (see FIG. 6) near the lower edge of the opening. The state has changed to a first state advantageous to the player and a second state unfavorable to the player.
[0054]
A starting ball guiding gutter 79 for guiding a winning ball (game ball 80) of the normally variable winning ball device 58 to the starting ball detector 60 on the back of the game board 40 is formed in the center of the back side of the mounting board 70. .
[0055]
In the special variable winning prize ball device 48 having the above-described configuration, when a large hit state is established according to the establishment of the predetermined condition, the open / close plate 49 is rotationally driven forward by the solenoid 50 about the rotating shaft 76 provided at the lower portion, and the prize is won. The area 73 is opened. In this way, the hit ball (game ball 80) is set to the open state (first state) in which the hit area 73 can be accepted. Then, after a predetermined number and a predetermined time have elapsed, the solenoid 50 is driven to rotate backward around the rotation shaft 76 to seal the winning area 73. In this way, the ball 80 is in the closed state (second state) in which it cannot be received in the winning area 73. In such a game state, when the opening / closing plate 49 shifts from the open state to the closed state, the opening / closing plate 49 is caught between the mounting board 70 of the special variable winning ball device 48 and the tip of the opening / closing plate 49 (the ball is seen). The problem is that such a ball looks like a game ball 80 falls on the side close to the game board 40, and when the cover is closed, the game ball 80 moves between the open / close plate 49 and the mounting board 70. Occurs when trying to pass. Conversely, when the game ball 80 falls on the side close to the double glass plate (in front of the game board 40), the game ball will pass between the opening / closing plate 49 and the mounting board 70 when the opening / closing plate is closed. No spheres are generated. The present invention is configured to solve the above-described problem. The details will be described below.
[0056]
The mounting board 70 of the special variable winning ball device 48 protrudes forward from the vicinity of the upper edge of the opening 72 across the width of the upper edge of the opening 72 as shown in FIG. A trajectory correction unit 71 is provided. The trajectory correcting section 71 in the present embodiment has a projection shape shown in the first embodiment (see FIG. 7A). The track correcting portion 71 has a width equal to the width of the upper edge of the opening 72 of the mounting board 70.
[0057]
Although the trajectory correcting section 71 in the present embodiment is configured by a protrusion near the upper edge of the opening, it is sufficient that the trajectory is raised from the upper edge of the opening or the vicinity of the upper edge of the opening. For example, as shown in FIG. The second embodiment that protrudes from the upper edge of the opening and the third embodiment that protrudes near the upper edge of the opening shown in FIG.
[0058]
In addition, the track correcting portion 71 in the present embodiment has a width equal to the width of the upper edge of the opening 72 of the mounting board 70, but extends over at least the width of the upper edge of the opening of the opening 72. The trajectory correcting portion 71 may be provided as long as it is provided, for example, by arranging a plurality of small protrusions near the upper edge of the opening 72 or near the upper edge of the opening so as to extend over the width of the opening 72. Is also good.
[0059]
In addition, although the track correcting portion 71 in the present embodiment is formed integrally with the mounting substrate 70, the present invention is not limited to this. For example, the track correcting portion 71 formed as a single unit may be mounted on the mounting substrate 70. You may.
[0060]
In addition, the opening and closing plate 49 in the present embodiment is configured to be rotated by the solenoid 50, but is not limited thereto, and may be configured to be rotated by a motor, for example.
[0061]
In the special variable winning ball device 48 having the above configuration, the game ball 80 falling from the game area 41 on the side close to the game board 40 comes into contact with the trajectory correction unit 71 and is close to the double glass plate. Since the flow path changes to the side (front), when the open / close plate 49 shifts from the open state to the closed state, the game ball 80 is prevented from passing between the tip of the open / close plate 49 and the mounting board 70, The pinching of the ball (game ball 80) between the tip of the opening / closing plate 49 and the mounting board 70 can be reduced.
[0062]
In the special variable winning ball device 48 according to the present embodiment, the game ball whose trajectory has been changed forward by the trajectory correcting unit 71 in the open state of the open / close plate 49 is prevented when the open / close plate 49 is closed. An opening / closing plate 49 configured to surely guide the 80 to the winning area 73 is provided.
[0063]
As shown in FIG. 6A, the opening / closing plate 49 is provided with a bent surface 74 whose lower part is rotatably supported by a rotation shaft 76 and approaches the inside of the opening as the distance from the rotation shaft 76 increases. I have. That is, the cross section of the opening / closing plate 49 has a U-shape, and includes a bent surface 74 in which an upper portion that is separated from the rotation axis by a predetermined distance is bent rearward. The opening / closing plate 49 has a positioning protrusion 75 on the lower front side. The positioning protrusion 75 determines an opening angle of the opening and closing plate 49 when the opening and closing plate 49 shifts from the closed state to the opened state.
[0064]
As shown in FIG. 6B, in the special variable prize ball device 48 including the trajectory correcting section 71 and the bending section 74, the game ball 80 flowing down on the side close to the gaming board 40 is changed by the trajectory correcting section 71. By changing the flow path forward, the game ball 80 is prevented from passing between the opening / closing plate 49 that is about to be closed and the mounting board 70, so that the occurrence of ball scattering can be suppressed. Also, when the game ball 80 tries to pass between the opening / closing plate 49 to be closed and the mounting board 70, as shown in FIG. Since the force for pushing the ball 80 acts, it is possible to suppress the generation of the ball.
[0065]
In the open state of the open / close plate 49, as shown in FIG. 6 (C), the game sphere 80 flowing down on the side close to the game board 40 has its flow path changed forward by the trajectory correction unit 71. When the plate 49 is opened, the bent portion 74 functions as a nearly vertical wall, so that even if the flow path of the game ball 80 changes forward, the bent portion 74 receives the game ball 80 and guides the game ball 80 into the winning area 73. Since the flow path is changed in the direction, even when the flow path of the game ball 80 changes forward by the trajectory correction unit 71 when the opening and closing plate 49 is opened, the game ball 80 can be reliably won in the winning area 73.
[0066]
In addition, although the open / close plate 49 in the present embodiment has a U-shape at the top, it is sufficient that at least the inside of the cross section (the winning area side) has a U-shape.
[0067]
Further, the opening / closing plate 49 in the present embodiment integrally forms the bent portion 74, but is not limited thereto. For example, the bent portion 74 may be attached to the opening / closing plate 49.

Further, the opening / closing plate 49 is provided with a bent portion 74 having a bent surface that approaches the inside of the opening 72 as the distance from the rotation shaft 76 increases. Since the bent surface is provided so as to approach the inside of the opening / closing plate 72, when the opening / closing plate 49 is closed, a force in the direction of pushing the game ball 80 toward the opening 72 inside the opening / closing plate is applied, so that the occurrence of ball bulging can be reduced. it can.
[0072]
【The invention's effect】
As is clear from the above description, in the invention of claim 1, since the trajectory correcting portion is provided at least over the width of the upper edge of the opening formed in the mounting board, the flow path of the game ball is reduced. It changes to the front by contacting the trajectory correction part, and it is possible to prevent the game ball from passing the position where the tip of the opening / closing member presses the ball against the mounting board, and the occurrence of ball squashing is reduced and the ball is removed. Work load can be reduced.
[0073]
According to the second aspect of the present invention, the trajectory of the game ball can be changed forward by the projection provided near the upper edge of the opening 70 or at the upper edge of the opening. be able to.
[0074]
According to the third aspect of the present invention, since the trajectory correcting portion having the same width as the upper edge of the opening of the mounting board is formed, it is possible to reduce the occurrence of bulging.
[0075]
Further, in the invention of claim 4, since the bent surface is provided so as to approach the inside of the opening as the distance from the rotation axis increases, the direction of pushing the ball toward the opening inside the opening / closing member by closing the opening / closing member. Since force acts, it is possible to reduce the occurrence of bulging.
