When the open / close door 48 is open, the inner surface of the open / close door 48 is inclined downward, and the rear end 53 of the open / close door 48 comes into contact with the lower wall surface of the guide member 64 to discharge the game ball P to the discharge port 67. A guide path 66 is formed to guide the vehicle. Therefore, it is possible to smoothly guide the game ball P that has entered the grand prize winning port 23 to the discharge port 67 and the detection path 65a.

After the detection switch 65 confirms that a predetermined number of game balls P have passed through the discharge port 69, the special winning opening 23 is closed by the opening / closing door 48. When the door 48 is in a substantially upright state, the game ball P is placed in a region below the front end of the discharge port 67 between the inner surface of the plate portion 51 of the door 48 and the front end of the discharge port 67. A game ball drop gap 70 that allows the drop to be dropped is formed.

  Therefore, a plurality of game balls P (for example, two to three) placed on the inner surface of the opening / closing door 48 slide down from the inner surface of the opening / closing door 48 and fall into the game ball dropping gap 70, and the game ball discharge channel 68. And it is discharged to the game area 5a through the discharge path 69. As a result, the game balls P that have entered more than the specified number do not pass through the discharge port 67, so that the detection switch 67 does not detect the game balls P as winning balls. Excessive winnings can be suppressed. In addition, it is possible to discharge the game balls P having a simple structure and exceeding the specified number from the variable winning device 15 to the game area 5a. Further, the variable winning device 15 of the embodiment does not increase the number of parts and the number of assembling steps, and is very advantageous in terms of production cost.

Here, a modified example in which the first embodiment is partially modified will be described.
1] In the first embodiment, the opening / closing door 48 and the pair of pivot shafts 56 are integrally formed. However, the opening / closing door 48 and the pair of pivot shafts 56 may be formed as separate members.

2] In the first embodiment, the pair of pivot shafts 56 are formed so as to protrude from the left and right ends of the opening / closing door 48 at the middle part of the opening / closing door 48 in the vertical direction. An insertion hole may be formed so as to penetrate through a predetermined portion in the vertical direction (for example, a middle step portion), and a single pivot shaft may be inserted into the insertion hole.
3] The shape of the inner surface of the open / close door 49 may be a shape other than that of the first embodiment as long as it is a shape for guiding the game ball P toward the outlet 67 of the back mechanism 17.

  Next, a pachinko machine according to a second embodiment will be described with reference to FIGS. The second embodiment is an example in which a variable winning device 15A having a structure different from that of the variable winning device 15 of the pachinko machine 1 according to the first embodiment is applied. In this pachinko machine, the same members as those of the pachinko machine 1 of the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

  As shown in FIGS. 11 and 12, the variable winning device 15A includes a decorative board 78, a game ball sorting board portion 78a, a winning opening 73, and a pair of open / close doors 74 that open and close the winning opening 73 in the left-right direction. An open / close door solenoid (not shown) for opening and closing the open / close door 74, a discharge port 80 for passing the game ball P in a direction substantially orthogonal to the game board surface and discharging it to the back side of the game board surface, and discharging from the discharge port 80 And a detection switch (not shown) for detecting the game ball P to be played.

  The pair of opening / closing doors 74 is a wing member that is disposed outside the front surface of the game board 5 and has a symmetrical shape, and has a bent portion 79 in which a tip end portion of a lower end thereof is bent inward. A pivot shaft 75 perpendicular to the board surface of the game board 5 is provided in each of the pair of opening / closing doors 74 in the middle in the vertical direction. The pair of pivot shafts 75 are pivotally supported between the front surface of the game board and the rear surface of the decorative plate 78.

  As shown in FIG. 11, when the pair of opening / closing doors 74 is open, the inner surfaces of the opening / closing doors 74 are downwardly inclined and the tips of the bent portions 79 of the opening / closing doors 74 are close to each other. A guide path 76 for guiding P to the discharge port 80 is formed. Therefore, it is possible to smoothly guide the game ball P entered from the winning port 73 to the discharge port 80.

  As shown in FIG. 12, in a state where the pair of opening / closing doors 74 is closed, that is, in a state where the opening / closing door 48 is upright, in the region below the discharge port 80, A game ball drop gap 77 that allows a drop of one or more game balls is formed between them. The game ball drop gap 77 communicates with a discharge path (not shown) for discharging the game ball P to the outside of the winning device 15A.

The operational effects of the variable winning device 15A of the second embodiment described above will be described.
After the predetermined number of game balls P entering the winning opening 73 is confirmed by the detection switch, the winning opening 73 is switched from the open state to the closed state by the pair of opening / closing doors 74. When these open / close doors 74 stand upright, a game ball drop gap 77 that allows a drop of one or more game balls is formed between the inner surfaces of the pair of open / close doors 74.

  Therefore, when the winning opening 73 is closed by the opening / closing door 74, a plurality of game balls P (for example, 2 to 3) placed on the inner surface of the opening / closing door 74 slide down from the inner surface of the opening / closing door 74 and play balls. It falls into the drop gap 77 and is discharged outside the winning device 15A. As a result, the game balls P that have entered the winning opening 73 beyond the prescribed number do not pass through the discharge port 80, and the excessive winning of the gaming balls P can be suppressed. In addition, it is possible to discharge the game balls P having a simple structure and having entered more than the prescribed number to the outside of the variable winning device 15A.

  Next, a pachinko machine according to a third embodiment will be described with reference to FIGS. The third embodiment is an example in which a variable winning device 15B having a structure different from the variable winning devices 15 and 15A of the pachinko machines of the first and second embodiments is applied. In this pachinko machine, the same members as those in the first and second embodiments are designated by the same reference numerals and description thereof is omitted.

  As shown in FIGS. 13 and 14, the variable winning device 15B includes a decorative plate 81, a game ball distribution plate portion 88, a winning port 82, and a pair of open / close doors 84 that open and close the winning port 82 in the left-right direction. An open / close door solenoid (not shown) for opening and closing the open / close door 84, and a discharge port 83a that is provided in the game board side member 83 and passes the game ball P in a direction substantially orthogonal to the game board surface and discharges it to the back side of the game board surface. And a detection switch (not shown) for detecting the game ball P discharged from the discharge port 83a.

  The pair of opening / closing doors 84 are blade members that are disposed outside the front surface of the game board 5 and have a symmetrical shape. A pivot shaft 85 perpendicular to the board surface of the game board 5 is integrally formed at the middle part of the open / close door 84 in the vertical direction. The pair of pivot shafts 85 are pivotally supported between the front surface of the game board 5 and the rear surface of the decorative plate 78.

  As shown in FIG. 13, when the pair of opening / closing doors 84 is open, the inner surface of the opening / closing door 84 is inclined downward, and the lower side of these opening / closing doors 84 faces the lower end thereof. The member 83 abuts to form a guide path 90 that guides the game ball P to the discharge port 83a. Therefore, it is possible to smoothly guide the game ball P entered from the winning port 82 to the discharge port 83a.

  As shown in FIG. 14, when the pair of open / close doors 84 is in the open state to the closed state, that is, in a state where the open / close door 84 is upright, the pair of open / close doors 84 is located in the region below the discharge port 83a. A game ball drop gap 87 that allows a drop of one or more game balls is formed between the inner surface and the game board side member 83 facing the inner surface. The game ball drop gap 87 communicates with a discharge path for discharging the game ball P to the outside of the winning device 15B.

The operation and effect of the third embodiment described above will be described.
When the winning opening 82 is closed by the opening / closing door 84, a plurality of game balls P (for example, two to three) placed on the inner surface of the opening / closing door 84 slide down from the inner surface of the opening / closing door 84 and the game ball dropping gap Drop to 87. Therefore, the game balls P that have entered the winning opening 82 exceeding the prescribed number do not pass through the discharge opening 83a, and the excessive winning of the gaming balls P can be suppressed. In addition, it is possible to discharge the game balls P that have a simple structure and have easily entered more than the specified number to the outside of the variable winning device 15B.
