Then, in a special operation state caused by a ball flowing down into the specific winning hole 19, the rotary chucker 4
When the ball flows into the trapping hole 47 of the fifth and the ball is supplied to the special starting port 48 with the rotation of the rotary chuck 45, the opening and closing plate 53 of the special winning port 52 is opened for about 10 seconds. When about 10 balls have flowed into the special winning opening 52, the opening operation is terminated even during the opening operation. Further, each time a game ball wins in the range of the effective limit number (usually 16) to the rotary chucker 45, the special winning opening 52 is opened, and thereafter the special operation state ends.

A distribution device 60, which will be described in detail with reference to FIGS. 10 to 13, is arranged below the starting gate 40.

The configuration of the distribution device 60 will be described. The distribution device 60 has a receptacle 61 whose upper surface is opened upward.
Is provided. The receiving opening 61 is provided with a guide circular groove 62, and a through hole 63 is formed in the center. Then, the guide circular groove 62
A bottom plate, which is also concentrically provided with a guide circular groove 64, is provided below. A discharge channel 66 for guiding a ball in a tangential direction of the guide circular groove 64 is formed at a rear side portion of the guide circular groove 64, and the through hole 63 is formed in a gutter 65 formed on a lower surface of the guide circular groove 62. Thereby, it communicates with the discharge channel 66 up and down.
The guide circular groove 64 is formed with an advantageous hole 67 at the front edge of the central portion and disadvantageous holes 68, 68 at the rear left and right, and the advantageous hole 67 is provided with a ball detection switch S1 (see FIG. 14). The disadvantageous gutters 69, 70 provided with the disadvantage holes 68, 68 are provided with a ball detection switch S2 (see FIG. 14).
It communicates with 0.

A discharge port 71 is provided on the distribution device 60. The discharge port 71 is provided in the specific winning hole 18
Therefore, the balls that have entered the specific winning hole 18 flow out onto the distribution device 60.

In such a structure, the front edge portion of the receiving port 61 projects from the game board 3 and becomes the substantial receiving port 61. The socket 61 is separated from the surroundings on the board surface by a nail row 73 struck between it and the variable winning apparatus 4, and communicates only with the drop hole 25 of the variable winning apparatus 4. And the socket 61
The ball that has entered passes through the through hole 63 of the guide circular groove 62, the trough 65, and falls onto the discharge channel 66. Then, due to the guiding action of the discharge flow path 66, the balls flow into the guide circular groove 64 from the tangential direction and revolve, and flow into either the advantageous hole 67 or the disadvantageous holes 68, 68. Then, the ball detection switch S1 is provided in the advantageous hole 67.
However, a ball detection switch S2 is provided in each of the disadvantage holes 68 and 68 (see FIG. 14), and a ball that has entered the advantage hole 67 by the ball discrimination by the switches S1 and S2 becomes an advantage ball, and the disadvantage hole 68, A ball that enters 68 is a disadvantageous ball.

Next, the operation of the variable winning device 4 will be described. A game ball is launched on the game board 3, and the starting gate 40
After passing through, any one of the random number tables stored in the storage device ROM connected to the central control unit CPU shown in FIG. 10 is selected, and the winning or losing is determined according to the selected value. Then, the combination display device 9 is driven through the symbol display driving circuit together with the supply of the prize sphere, and the symbol display portions 10a, 10b, 10c are started to fluctuate, and after about 5 seconds, it is judged whether or not the symbol is hit. Therefore, the symbols of the symbol display portions 10a, 10b, 10c are determined from the random number table, and the symbols are stopped sequentially. Then, the symbol display units 10a, 10
The symbols b and 10c are the same symbol, or the symbol display unit 10
When a and 10b are the same symbol and the symbol display portion 10c is the "corresponding" symbol, it is a "big hit", the speaker emits a sound by the voice processing device shown in FIG. 14, and the solenoid 33 is driven. The opening / closing actuating piece 14 is in an inclined state (open state), and the operation shifts to the following operation that enables a predetermined gain.

When the game balls continuously flow into the starting gate 40, the standby recording lamp row 11 is sequentially turned on and is held up to four times.

That is, the opening / closing operation piece 14 is opened for about 5.9 seconds, and during this opening, several hitting balls flow in from the opening 12. On the other hand, the rotation distributor 20 rotates counterclockwise at a low speed in the closed state of the opening / closing operation piece 14, but rotates at a high speed with a big hit, and as shown in FIGS.
3 coincides with the ball inlet 15 formed at the right end of the ball passage 8,
Moreover, the guide port 26 is stopped in a state in which the guide port 26 is positioned almost directly below. Therefore, the balls that enter through the opening 12 are
Balls flow into the main entrance / exit 23. At this time, the retention groove 2
The sub inlet / outlet 24, which communicates with the main inlet / outlet 23 via 5, is located at a left position deviated from the center by about 60 °, has a retention groove 25 in a V shape, and has a small protrusion 27 to prevent its inertial outflow. Since it is blocked, only _two balls x ₁ and x ₂ can stay in the stay groove 25, and the rest will remain in the ball inlet 15 or on the ball passage 8.

On the other hand, when the third ball x ₃ is detected by the ball detecting device 15a provided at the ball inlet 15, the rotary distributor 20 rotates counterclockwise. Then, as shown in FIG. 6, when the guide port 26 coincides with the ball inlet port 15, only the ball x ₃ flows into the guide port 26. At this time, the sub inlet / outlet 24 coincides with the normal winning hole 17, and therefore, the two balls x ₁ and x ₂ in the retention groove 25 are the same as the normal winning hole 17
Discharged to the side. Then, the rotary distributor 20 further rotates, and when the guide port 26 coincides with the specific winning hole 18 as shown in FIGS. 4 and 7, the ball is discharged to the specific winning hole 18. Further, at this position, the sub inlet / outlet 24 coincides with the ball inflow port 15 and the main inlet / outlet 23 coincides with the ordinary winning hole 17, so that four or more balls x ₄ ~ are continuously retained in the retaining groove 25.
It will drop through the inside to the normal winning hole 17 side and be discharged.

Each of these operations is controlled by drive control means composed of a central control unit CPU.

Then, when the ball x ₃ flows down into the specific winning hole 18, it is detected by a ball detection device arranged in the flow passage, a special operation state is established, and the right of big hit is generated. That is, even if the combination display device 9 is a combination that gives a predetermined big hit, it is not effective unless three or more balls flow from the opening 12. Thus, a winning condition for generating a big hit is added.

The balls that have entered the specific winning hole 18 are in the flow passage 72.
Through the discharge port 71 to the receiving port 61 of the sorting apparatus 60. Then, through the process described above, the advantageous holes 67,
It flows into one of the disadvantageous holes 68, 68 and is sorted into an advantageous ball and a disadvantageous ball. In addition, the advantageous hole 67 and the disadvantageous holes 68, 6
Although there is a difference in the content of the profit in any of the eight, as will be described later, all of them are in a special operating state and can receive a predetermined profit. That is, the ball enters the specific winning hole 18, resulting in a special operation state.

Here, as shown in FIG. 14, a sound processing device controlled by the central control unit CPU so as to clearly inform whether it has entered the advantageous hole 67 or the disadvantageous holes 68, 68. , Different sound effects are generated from the speakers based on the ball detection by the ball detection switches S1 and S2 in the holes 67 and 68, respectively.
Thereby, the player can easily determine the state.

As described above, the contents of the special operation state are different when the balls enter the disadvantageous holes 68, 68 and when they enter the advantageous holes 67. This difference can be made by changing the limit number (hereinafter, referred to as an effective limit number) of balls that can enter the special starting port 48 that can open the special winning port 52.

More specifically, the effective limit number is 16 when it is distributed to the effective holes 67 and distributed to the effective balls, and it is 2 when it is distributed to the disadvantage holes 68 and 68 to the invalid balls. To do. Then, when entering the disadvantageous holes 68, 68 or the advantageous hole 67, the balls flow into the catching holes 47 of the rotary chucker 45 during the special operation state, and the balls are caused by the rotation of the rotary distributor 46. When supplied to the special starting opening 48, the opening / closing plate 53 of the special winning opening 52 is opened for about 10 seconds. When about 10 balls flow into the special winning opening 52, the opening operation ends even if the opening operation is being performed. Then, the special operation state ends with the exhaustion of the effective limit number.

Thus, the player is more likely to be provided with the gain associated with the big hit due to the generation of the advantageous ball than the generation of the disadvantage ball.

As a means for producing such a difference in profit, a means for producing a difference in the opening time of the opening / closing plate 53 can also be adopted. That is, the opening time of the opening / closing plate 53 is set to about 10 seconds in the special operation state based on the effective ball, and about 5 seconds in the special operation state based on the generation of the invalid ball.

Next, means for changing the hit probability of the symbol display portions 10a, 10b, 10c controlled by the combination display device 9 after the special operation is finished to make a difference in profit can also be applied.

That is, when an effective ball is generated by entering the advantageous hole 67, the symbol display section 10 for the next time when the special operation is finished.
The hit probability of a, 10b, and 10c is improved 10 times more than usual. On the other hand, in the case where an ineffective ball is generated by entering the disadvantageous holes 68, 68, the normal winning probability is set even after the special operation ends. On the other hand, in the sorting device, disadvantageous holes 6
When entering 8, the second special winning state is entered.

This configuration will be described in more detail. The storage device ROM connected to the central control unit CPU has "0" to
A random number value that circulates 276 frames up to “275” is stored.
As the ball passes through 40, one of them is selected. Then, only when this value is “0”, for example, the hit is regarded as a hit, and when the value is other than that, it is determined as a loss. The change of the combination display device 9 is started, and based on the result of the determination, a winning or missing symbol is selected, the driving of the combination display device 9 is stopped, and the symbol display unit 10 is stopped.
a, 10b, and 10c.

Therefore, normally, the winning probability is 1/276.
It is. However, when a ball enters the advantageous hole 67 and the ball detection switch S2 is turned on, as described above, the effective limit number is entered in the special starting port 48, and when the special operation state ends, until the next hit occurs. , Among the random number values, for example, “0” to “9” is hit, and the hit probability is
10 times. In this case, in the next hitting operation, even if a ball enters the advantageous hole 67, no advantageous operation occurs. It should be noted that the probability may be high continuously, in this case, unless a ball enters the disadvantageous holes 68, 68 during a big hit,
The winning probability will be maintained at a high rate.

Further, even when entering the disadvantageous holes 68, 68, the probability may be higher than in the normal state. For example, the probability is increased 10 times higher than usual based on the ball inflow of the advantageous hole 67, and the probability is increased 5 times higher than usual based on the ball inflow of the disadvantageous holes 68, 68. Also in this case, a significant difference can be generated in profit between the effective ball and the invalid ball. In this case, the probability returns to the normal probability at the next big hit.

The series of operations described above can be easily executed by the control commanding means including the central control unit CPU and the like shown in FIG. The central control unit CPU also serves as the drive control means of the variable winning apparatus 4, as described above.

4 of the plurality of balls flowing in from the ball entrance 12 by the opening operation for a predetermined time, only one of the balls is specified in the specific winning hole 1
8, the other balls are led to the normal winning hole 17, and the balls which enter the specific winning hole 18 are sorted into advantageous balls and disadvantage balls by the sorting device 60 provided on the game board 3, which is advantageous. When the ball is distributed to the ball, the operation that is advantageous to the player is generated as compared to when the ball is disadvantaged, so that the distribution device 60 has a thrilling expectation on the whereabouts of the ball. In addition, the operation of the play board surface can be varied, and there is an excellent effect that the interest of the pachinko game can be further enhanced.
