[0007]

1 and 2 show one embodiment of the present invention. FIG. 1 is a perspective view of a main portion showing a closed state of both guide rods, and FIG. 2 shows an opened state of both guide rods. Partial perspective views are respectively shown.
In the figure, 10 indicates an accessory body provided on the board surface (not shown) of the game board of the ball game machine.
When roughly classified, a pair of guide rods 20 and 20, one end portion of both guide rods 20, here, a guide portion 30 for guiding the game ball B to the end portion on the front side of the board, and both guide rods 20. The other end of
Here, it is provided with a rotary cam 40 located at an end portion on the back side of the board.

One end of the pair of guide rods 20, that is, the end on the front side of the board in this case, is axially fixed to the accessory body 10 with axial centers 21 and 21 axially fixed in the vertical direction. There is. Then, both guide rods 20 are gently inclined downward from one end side, here the front side of the board surface, to the other end side, here, the back surface side of the board, so that the game ball B moves from the front side of the board surface to the back surface of the board. I try to roll to the side.

By rotating both guide rods 20 about an axis 21 on the front side of the board, as shown in FIG.
It is configured so that it can be in two states, a closed state in which a game ball rolling over does not fall and an open state in which it can fall. More specifically, in the closed state, both guide bars 20 are substantially parallel to each other with an interval smaller than the diameter of the game ball B,
Further, in the open state, the distance between both guide rods 20 is opened in a V shape so as to become larger than the diameter of the game ball B as it goes toward the back side of the board.

Further, in the middle of the length of both the guide rods 20, more specifically, on the front side of the rotary cam 40, bent portions 22, 22 which are bent outward in a semicircular shape are formed respectively. Then, the inner diameter of the circular empty portion formed between both bent portions 22 is
The diameter is larger than the diameter of the game ball B. Therefore, in the closed state, when the game ball B rolling both guide bars 20 rolls to the position of both bending portions 22, both bending portions 22
Falls downward from within the interval.

In addition, in the accessory body 10, below the bent portions 22 of the guide rods 20, the first winning opening 11 for the game ball B to win.
Are formed. It should be noted that the game ball B that has won the first winning opening 11 is detected by a detector (not shown) in the middle of its flow, becomes a special winning ball, and the game proceeds under conditions that are more advantageous than general winning. You can In addition, the accessory body 10
In front of the first winning opening 11, a second winning opening 12 is formed in which the game ball B dropped from within the interval between the guide bars 20 in the open state is won. The game ball B that has won the second winning opening 12 is detected by a detector (not shown) in the middle of its flow, and becomes a general winning ball.

The guide portion 30 has a substantially U-shaped cross-section that opens upward, is located above both guide rods 20, and is substantially elliptical so as to surround both guide rods 20 in a plane. Is formed in. Then, on both sides of the guide portion 30, there are a pair of side walls 31, 32 facing each other.
The facing interval of 32 is set wider than the diameter of the game ball B so that the game ball B can pass through the facing interval of the side walls 31 and 32.

The bottom 33 of the guide portion 30 is inclined so that the front side of the board surface is the lowest and the bottom side of the board surface is the highest. Then, the game ball B introduced into the accessory body 10 from the board surface of the game board falls to the bottom 33 of the guide portion 30 on the back side of the board, and rolls toward the front side of the board due to the downward slope. The guide section 30
Of the both side walls 31, 32, the side wall 32 located on the inner side is formed with a guide opening 34 facing the front side of the board surface of both guide bars 20 and having a U-shaped cross section through which the game ball B can pass. Therefore, the game ball B rolling on the bottom 33 of the guide portion 30 is
Through 34, they fall to the front end of both guide rods 20.

The rotating cam 40 is rotatably supported by a drive source such as a stepping motor in the opening direction of the guide rods 20 and has a pair of guide grooves 41, 41 formed on the outer circumference in the rotating direction. Has been done. The drive source is not limited to the stepping motor, and a normal DC / AC motor or a plunger may be used. Both guide grooves
41 are parallel to each other facing each other and have a narrow portion 42 (FIG. 1) and a wide portion 43 (FIG. 2). Then, the front ends of the guide rods 20 on the back side of the board are inserted into the guide grooves 41, respectively.

Therefore, in the portion 42 where the distance between the two guide grooves 41 is narrow, both guide rods 20 are closed, as shown in FIG. 1, while in the wide portion 43, both guide rods 20 are closed, as shown in FIG. 20 is open. Then, since the rotary cam 40 is rotated by the stepping motor, the both guide rods 20 are alternately converted into the closed state and the open state. The stepping motor is used because it is easy to control the state conversion of both guide rods 20.

The operation of this embodiment will be described below. The game ball B introduced into the accessory body 10 from the board surface of the game board drops to the bottom 33 of the guide portion 30 on the back surface side of the board, and then, due to the downward slope of the bottom 33 of the guide portion 30, moves toward the front surface of the board. To roll. Then, when the game ball B rolls to the position of the guide opening 34 of the guide portion 30, it falls through the guide opening 34 to the end portions of both guide bars 20 on the front side of the board surface.

At that time, as shown in FIG.
When 20 is in the closed state, since both guide bars 20 are gently inclined downward from the front side of the board toward the back side of the board, the game ball B straddles the guide bars 20. ,
Rolls along both guide bars 20 from the front side of the board to the back side of the board. Then, when the game ball B rolls to the position of each bent portion 22 of both guide bars 20, the inner diameter of the circular empty portion formed between both bent portions 22 becomes larger than the diameter of the game ball B. Since it is formed, it falls downward from within the circular interval of both bent portions 22.

The game ball B, which has dropped downward, has both guide bars 20.
The first prize opening 11 located right below each of the bent portions 22 is won. As described above, the gaming ball B that has won the first winning opening 11 is detected by a detector (not shown) in the middle of its flow, and becomes a special winning ball, which is a more advantageous condition than the general winning. You can proceed with the game. In contrast, Figure 2
As shown in, when both guide rods 20 are in the open state, the distance between both guide rods 20 becomes larger than the diameter of the game ball B as it goes toward the back of the board. The game ball B rolling on both guide bars 20 falls downward between the guide bars 20 during the rolling.

The game ball B which has dropped downward wins the second winning opening 12 located in front of the first winning opening 11. Incidentally, as described above, one of the game balls B that has won the second winning opening 12 is detected by a detector (not shown) while flowing down, and becomes a general winning ball. Furthermore, considering that both guide bars 20 are alternately converted into the closed state and the open state, there is an opportunity for the game ball B to roll on the both guide bars 20 when the closed state and the open state change. In many cases and in many cases, there is a high probability that the ball will fall to the position of each bent portion 22 of both guide rods 20 and will fall during the rolling and win the second winning opening 12.

The two guide rods 20 may be electrically controlled not only by alternately changing between the closed state and the open state but also by maintaining the closed state or the open state for a certain period of time. further,
The shape of the rotary cam 40 may be changed and mechanically controlled so that the closed state or the open state of both guide rods 20 is maintained for a certain period of time. For example, by increasing or decreasing one of the portion 42 (FIG. 1) and the wide portion 43 (FIG. 2) of the guide grooves 41 with a narrow interval,
The time between the closed state and the open state of both guide rods 20 can be freely changed.

In the embodiment shown in the drawings, both guide bars
Although 20 is inclined downward from the front side of the board toward the rear side of the board, conversely, it may be inclined downward from the back side of the board toward the front side of the board. In that case, the first winning port 11 may be arranged on the front side of the board surface of both guide rods 20, and the second winning port 12 may be arranged on the rear side of the board surface. Further, both guide rods 20 may be arranged in parallel or obliquely with respect to the board surface. For example, when both guide rods 20 are arranged parallel to the board surface, both guide rods 20 may be inclined downward from the left side to the right side or from the right side to the left side.

In addition to this, in the embodiment shown in the drawings, the end portions of both guide rods 20 on the front side of the board surface are axially fixed to the accessory body 10 with the axis 21 so that both guide rods 20 have their respective axis centers. Although it is configured to open in a V shape from 21, only one end of each of the guide rods 20 may be axially fixed and the other may be fixed. Both guide rods 2 without axially stopping each end of both guide rods 20
May be configured to slide in parallel with each other.
