DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pachinko machine, and more particularly, to a pachinko machine that simply and quickly discharges the number of prize balls paid out in response to a prize ball according to the type of a prize port. .

[0002]

2. Description of the Related Art Conventionally, as a pachinko machine that changes the number of prize balls to be paid out according to the type of winning opening, there is Japanese Utility Model Laid-Open No. 63-38571. According to this publication, both the winning ball from the winning ball port and the winning ball from the specific winning port pass through a common passage, and the signal of a detector provided in the passage is counted via a counter. On the other hand, a specific winning detector is provided in the specific winning opening, and a signal from the detector is integrated through a specific winning ball counter. Then, when the specific winning ball counter becomes non-zero, an interrupt signal is issued, and a predetermined prize ball is counted and discharged via a prize ball discharging device. Subtract one. Then, when the value of the specific winning ball counter becomes zero, an interrupt signal is issued, and different preset prize balls based on the value of the counter are discharged. By doing so, it is possible to correspond to a counter that counts the winning balls from the specific winning opening and the winning balls from the winning opening without distinguishing them, and it is possible to provide a common passage for the winning balls.

[0003]

However, as described above, a counter for a prize ball and a counter for a specific prize ball are provided so that 1 is subtracted after the discharge of the prize ball is completed. When there is, an interrupt signal is issued, a predetermined number of prize balls are discharged,
A configuration in which an interrupt signal is issued even when the specific winning ball becomes zero and a predetermined number of prize balls are discharged according to the value of the counter becomes complicated, and the control method is complicated, and it may not be possible to respond quickly. Occurs. Further, since the prize ball counting device has only one ball cutting rotary body, it takes a long time to process a predetermined number of prize balls to be counted and discharged based on a discharge command from the counting control device. Therefore, if the number of winnings is many in a short time, the prize balls are continuously discharged, and the player feels strange. Further, when the counting is performed by using a conventional ball cutting rotary body arranged in a plurality of coaxially arranged counters, only the number of times the number of the arranged ball cutting rotary bodies can be counted. For example, when two ball-rotating bodies are coaxially arranged, counting for a multiple of 2 is possible but not for an odd number. Therefore, for example, when the number of balls to be ejected at the time of winning is an odd number, it cannot be processed by the above-described counter. In addition, installing a plurality of the same counters as the conventional prize ball counter is disadvantageous in terms of cost and control. Therefore, the present invention provides a pachinko machine that solves such a disadvantage.

The operation of the prize ball counting device 1 will be described with reference to FIGS. The right part of FIG. 7 shows a block diagram of the prize ball counting device 1. Based on an input signal from the main control unit, the counting control device sends signals to the electromagnets 26a and 26b to discharge the prize ball. That is, based on the number of prize balls from the main control unit, the counting control device outputs the number of rotations n1 of the three ball cutting rotators 7a and the number of even numbers of two at once.
(N1 + n)
2) is determined to be the minimum rotation speed. For example, when the number of discharges is 13, n1 is 3, n2 is 2, and the discharge number is 14.
In this case, n1 is set to 2 and n2 is set to 4, and if the number of discharges is 15, n1 is set to 3 and n2 is set to 3. The counting control device turns on (ON) each of the electromagnets 26a and 26b. , Non-conduction (OF
The number of times F) is defined as n1 and n2. FIG. 8 shows a time chart of “ON” and “OFF” of each electromagnet when the number of discharged prize balls is 13. Electromagnet 26a is "ON"
At (time t1), the projection 29a of the stop plate 25a comes off the notch 23a, overcoming the dead weight of the stop rod 27a and the stop plate 25a and the reaction force of the spring 28a, and the ball cutting rotator 7a receives the prize in the ball receiver. The ball 5 starts rotating under its own weight. Immediately thereafter (time t2), the electromagnet 26a is turned "OFF". Electromagnet 2
6a is turned "OFF", the stop bar 25a is stopped by the own weight of the stop rod 27a and the stop plate 25a and the urging force of the spring 28a.
The protrusion 29a maintains a state in which it is urged so as to contact the side wall rotating surface of the ball cutting rotary body 7a, and when it reaches the notch 23a, the protrusion 29a contacts the notch 23a to rotate the ball. The rotation of the body 7a is prohibited. Hereinafter, at times t3, t4 and t
5. At t6, the same operation as described above is performed. That is, the counting control device sets “OF” immediately after turning the electromagnet 26a “ON”.
F ”is repeated three times to obtain 3 × 3
A total of 9 prize balls are discharged at a time. On the other hand, the counting control device also controls the electromagnet 26b at the same time, and turns on at times t1 and t3, and discharges four prize balls 2 × 2 times. By the above operation, nine prize balls are counted and discharged by the ball cutting rotator 7a, and four prize balls are counted and discharged by the ball cutting rotator 7b.
Discharge individually.

The times t1 and t1 when the electromagnet is turned "ON"
3. The time T1 between t3 and t5 is equal to or longer than the time required for the prize ball to be rotated and discharged while being received by the ball receiving portion of the ball cutting rotating body, and the ball receiving portion having a different number of prize balls in the ball receiving portion. Although it may be determined differently for each rotator, in the present embodiment, it is set to a longer time than it takes the longest for simplicity. The time T2 when the electromagnet is turned from “ON” to “OFF” is “O
It is within the time from the time (t1, t3, t5) set as "N" until the next notch arrives, and is simple for a ball cutting rotator having a different number of prize balls in the ball receiving portion. For this reason, it is uniformly set to the shortest time (T2). In the above-described embodiment, the number of prize balls in the ball receiving unit is two and three ball cutting rotators are provided side by side.
It goes without saying that the number of ball receiving portions may be constituted by other combinations. Further, although the ball cutting rotator of the above embodiment is rotated by its own weight of the prize ball, it may be directly connected to a pulse motor to control the rotation speed by starting and stopping the pulse motor.

Next, the winning openings 113a to 113c and the specific winning opening 1
The control of paying out the prize balls 5 to the winning balls 5a entering 14a and 14b will be described. The control block is shown in FIG. 7, and the control flow is shown in FIG. In step 1, it is detected whether or not there is a winning ball 5a from any of the specific winning ports 115a and 115b. If there is, in step 2, 1 is added to the specific ball counter and integrated. If not, go to step 3. Next, in step 3, it is determined whether or not the prize ball detector 125 has detected the prize ball 5a. If not, the process returns to step 1 because the prize ball is not discharged. Conversely, if detected, the electromagnet 128 is excited in step 4 to discharge the winning ball 5a via the winning ball discharging device 120, and is de-energized after a predetermined period of time.
Discharge one of a. Next, in step 5, it is determined whether or not the winning ball 5a is a specific ball by a specific ball counter. If the specific ball counter is zero, the winning ball is not a specific winning ball, so the process proceeds to step 6. The number of prize balls to be discharged is set to A, and the process proceeds to step 9. In step 5, if the specific ball counter is not zero, that is, since the winning ball is the specific winning ball, the number of prize balls to be ejected is set to a different number B (step 7), and 1 is determined from the value of the specific ball counter. , And the process proceeds to step 9 (step 8). That is, the subtraction is performed when the winning ball detector 125 detects the winning balls 5a from both the winning ports 113a to 113c and the specific winning ports 114a and 114b, and discharges the prize balls separately from the specific winning balls. This is to make it correspond. In step 9, after determining the number of rotations of the ball cutting rotators 7 a and 7 b for counting and discharging odd and even numbers based on the values of the prize balls A and B to be discharged as described above, the counting and discharging are performed. (Step 10), and after the discharge is completed, the process returns to Step 1. In the above example, the operation of the prize ball discharging device 120 is performed in a flow so as to be performed through the main control unit. However, when the prize ball detector 125 detects the prize ball, the electromagnet 128 is turned “ON” and “OFF”. May be provided separately. That is, in the operation of discharging the prize ball of the present invention, the main control unit sets the prize ball 5a to the prize ball detector 12
It is configured to be operable upon detection at 5.
