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 easily and quickly discharges the number of prize balls paid out corresponding to winning balls according to the type of winning hole. .

[0002]

2. Description of the Related Art Conventionally, Japanese Utility Model Publication No. 63-38571 discloses a pachinko machine that changes the number of prize balls to be paid out according to the type of a winning opening. According to this publication, both the winning ball from the winning ball opening and the winning ball from the specific winning opening pass through the common passage, and the signal of the detector provided in the passage is counted through the counter. On the other hand, a specific prize detector is provided at the specific winning opening, and signals from the detector are integrated via a specific prize ball counter. Then, when the specific winning ball counter becomes non-zero, an interrupt signal is issued to count and discharge the preset prize balls through the prize ball discharging device, and after completion of discharging, the counter and the specific winning ball counter respectively. Subtract one. Then, when the specific winning ball counter reaches zero, an interrupt signal is issued to discharge different prize balls set in advance based on the value of the counter. By doing so, it becomes 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 distinction, and it is possible to provide a common passage for the winning balls.

[0003]

However, as described above, a counter for prize-winning balls and a counter for specific prize-winning balls are provided so as to subtract one from each after the prize balls have been discharged. When there is, an interrupt signal is issued, and a predetermined number of prize balls is discharged,
Even when the specific winning ball becomes zero, an interrupt signal is issued to discharge the predetermined number of prize balls according to the value of the counter, which complicates the control system and may not be able to respond quickly. Occurs. Further, since the prize ball counting device has only one ball-cutting rotating body, it takes a long time to process a predetermined number of prize balls to be counted and discharged based on the discharge command from the counting control device. Therefore, if the number of winnings is a large number of times in a short time, the discharge of the prize balls will continue forever, which makes the player feel uncomfortable. Further, when a conventional counter composed of a plurality of sphere-cutting rotary bodies arranged coaxially is used, the number of times the number of the sphere-cutting rotary bodies arranged can be multiplied. For example, when two spherical cutting bodies are arranged coaxially, counting can be performed for a multiple of 2, but not for an odd number. Therefore, for example, when the number of balls discharged when a prize is won is an odd number, it cannot be processed by the counter. Further, it is disadvantageous in terms of cost and control to install a plurality of the same objects as the conventional prize ball counter. Therefore, the present invention provides a pachinko machine that eliminates such inconvenience.

According to the pachinko machine of claim 1, the winning balls that have entered the specified winning opening are counted by the specified ball counter, and the winning balls that have entered the specified winning opening and other winning openings are placed in the taxiway. It is detected by the detector. When the winning ball detector detects a winning ball, the winning ball discharging device discharges the winning balls one by one and detects whether or not the specific ball counter is zero. If the winning ball is zero, the winning ball is detected. Is from the winning ball opening, and if it is non-zero, it is from the specific winning opening, and in such a case, 1 is subtracted from the value of the specific ball counter. Therefore, in accordance with the above-mentioned distinction, the number of prize balls to be discharged is set in advance and the prize balls are discharged through the prize ball counting device. The prize ball counting device according to claim 2 determines the number of revolutions of the even number of ball-turning rotary bodies and the number of rotations of the odd number of ball-turning rotary bodies corresponding to the number of prize balls to be counted in advance. Then, according to the number of revolutions of each of the ball-cutting rotating bodies, the rotating body is rotated and then stopped by a stop mechanism. Therefore, the prize balls can be completely discharged in a short time. The pachinko machine according to the third aspect enables the prize balls to be discharged according to the distinction of the winning openings in a short time as described above.

4 to 6 show the prize ball counting device 1, FIG. 4 is a front sectional view, FIG. 5 is a left sectional view of FIG. 1, and FIG. 6 is a right sectional view of FIG. The prize ball counting device 1 has an alignment path 1
03 and the prize ball 5 falling through the meandering guide path 3. The base 4 of the prize ball counting device 1 is made of synthetic resin in a side view H shape through the partition plate 2, and is pivotally supported by a pair of three-point supporting members (not shown) in the central portion. The fixed shaft 10 is provided with ball-turning rotating bodies 7a and 7b, which are rotated by the weight of the prize balls 5 and separate (count and discharge) the prize balls 5 into odd number and even number. That is, taxiway 3
The ball receiving portion 6a is formed by a partition wall 22a having a substantially triangular cross section, which is placed upright on the circumference so that the prize cutting balls 5 can be received and the odd numbered ball cutting rotating bodies 7a can be cut into three pieces (count discharge).
On the other hand, on the other hand, the sphere-cutting rotating body 7b as an even number is formed with four sphere-receiving portions 6b by partition walls 22b having a substantially triangular cross section in the periphery so that two sphere-cutting rotating bodies 7b can be cut off. The bodies 7a and 7b are independently rotatably attached to the fixed shaft 10. The rotating direction of the ball cutting rotary body 7a is counterclockwise (FIG. 5), and the rotating direction of the ball cutting rotary body 7b is clockwise (FIG. 6).

As a stopping mechanism for the ball-turning rotary bodies 7a and 7b, three positions are provided at 120 ° intervals on the peripheral edge of the side wall 23 of the ball-cut rotary body 7a and 90 ° intervals at the peripheral edge of the side wall 24 of the ball-cut rotating body 7b. Notch portions 23a and 23b formed at four locations in
A projection 29a which can be brought into contact with and separated from the cutouts 23a, 23b,
29b and L-shaped stop plates 25a and 25b, which are lift plates 27a and 27b of electromagnets 26a and 26b via springs 28a and 28b.
Are linked to. The stop plates 25a, 25b are installed so as to act on the cutouts 23a, 23b from above, and when the electromagnets 26a, 26b are "OFF", the weights of the lift bars 27a, 27b and the stop plates 25a are reduced. Two
The weight of 5b and the elastic force of the springs 28a, 28b are urged to abut the side walls of the ball-cutting rotating bodies 7a, 7b, and the projections 29a, 29b abut the cutouts 23a, 23b to rotate the balls. The rotation of the bodies 7a and 7b is prohibited. In that state, when the electromagnets 26a and 26b are energized (ON), the weights of the lift rods 27a and 27b, the weights of the stop plates 25a and 25b, and the biasing forces of the springs 28a and 28b are overcome, and the projections 29a and 29b are notched. After separating from 23a and 23b, the ball-cutting rotating bodies 7a and 7b rotate by the weight of the prize ball 5. In that state, the electromagnets 26a and 26b are de-energized (OF
When it is set to F), the protrusion 29 is produced by the same action as described above.
The a and 29b come into contact with the cutouts 23a and 23b and are prohibited from rotating. The electromagnets 26a and 26b are mounted above the ball-cutting rotors 7a and 7b, and the stop plates 25a and 25b act on the cutouts 23a and 23b from above to prevent the ball-cutting rotors 7a and 7b from rotating. Therefore, even if the elastic force of the springs 28a and 28b decreases, the lift rod 27
The ball-cutting rotating bodies 7a and 7b can be smoothly stopped by the weights of a and 27b and the weights of the stop plates 25a and 25b. Reference numeral 31 denotes an operation hole formed in the partition plate 4, and the stop plate 25b is lifted from the operation hole 31 by a driver or the like to freely rotate the ball-cutting rotating body 7b, and the prize ball in the guideway 3 Discharge 5.

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 the input signal from the main control part, the counting control device sends signals to the electromagnets 26a and 26b to discharge the prize ball. That is, the counting control device is based on the number of prize balls from the main control unit, and the number of discharges once is the odd number of three ball-cutting rotary bodies 7a, the rotational speed n1 and the even number of two.
Sum of the number of revolutions n2 of the ball-cutting rotor 7b (n1 + n)
2) is determined so that it becomes the minimum speed. For example, if the number of emissions is 13, n1 is 3, n2 is 2, and the number of emissions is 14
When the number of discharges is 15, n1 is set to 2 and n2 is set to 4, and when the number of discharges is 15, n1 is set to 3 and n2 is set to 3, and the counting control device sets the electromagnets 26a and 26b to conduction (ON). , Non-conducting (OF
The number of times of F) is set to 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 weight of the stop rod 27a and the stop plate 25a and the reaction force of the spring 28a are overcome, and the projection 29a of the stop plate 25a comes out of the notch 23a, and the ball cutting rotary member 7a receives the prize in the ball receiving portion. The ball 5 starts to rotate due to its own weight. Immediately thereafter (time t2), the electromagnet 26a is turned off. Electromagnet 2
Since 6a is turned "OFF", the weight of the stop bar 27a and the stop plate 25a and the biasing force of the spring 28a cause the stop plate 25 to move.
The protrusion 29 of "a" maintains the state of being urged so as to contact the side wall rotating surface of the sphere cutting rotary member 7a, and when reaching the notch 23a, the protrusion 29a comes into contact with the notch 23a to make the sphere cutting rotation. The rotation of the body 7a is prohibited. Below, times t3, t4 and t
At 5 and t6, the same operation as described above is performed. That is, the counting control device immediately performs the "OF" operation immediately after turning on the electromagnet 26a.
By repeating “F” three times, 3 × 3
A total of 9 prize balls will be ejected each time. On the other hand, the counting control device also controls the electromagnet 26b at the same time, and at times t1 and t3, it is turned "ON" to discharge 4 prize balls at 2 times 2 times. By the above operation, 9 prize balls are discharged from the ball-slicing rotary member 7a and 4 prize balls are discharged from the ball-slicing rotary member 7b.
Discharge individually.

The times t1 and t when the electromagnet is turned "ON"
3, the time T1 between t3 and t5 is longer than the time until the prize balls are rotated and discharged while being received in the ball receiving portion of the ball cutting rotating body, and the number of prize balls in the ball receiving portion is different. It may be determined to be different for each rotating body, but in the present embodiment, for the sake of simplicity, it is set to a longer time that takes the longest time. Also, the time T2 for turning the electromagnet from "ON" to "OFF" is "O".
It is within the time from the time of "N" (t1, t3, t5) to the arrival of the next notch, and it is also convenient for ball-turning rotating bodies with different numbers of prize balls in the ball receiving part. Therefore, the shortest time (T2) is set uniformly. In the above-mentioned embodiment, the ball receiving portion has two and three ball-slicing rotating bodies as prize balls.
It goes without saying that the number of ball receiving portions may be configured in another combination. Further, although the ball cutting rotary body of the above-mentioned embodiment is rotated by the weight of the prize ball, it may be directly connected to the pulse motor to control the rotation speed by starting and stopping the pulse motor.

Next, the winning holes 113a to 113c and the specific winning hole 1
The control of the payout of the prize balls 5 with respect to the winning balls 5a that have entered 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 one of the specific winning openings 115a and 115b, and if there is, the specific ball counter is incremented by 1 in step 2 to be integrated. If not, go to step 3. Next, in step 3, it is determined whether or not the winning ball detector 125 has detected the winning ball 5a. If there is not, the prize ball is not discharged, and the process returns to step 1. On the contrary, if detected, the winning ball 5a is discharged through the winning ball discharging device 120 in step 4, so the electromagnet 128 is excited, and after a predetermined time, the winning ball 5a is de-excited.
Discharge one of a. Next, in step 5, the specific ball counter determines whether or not the winning ball 5a is a specific ball. 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 sphere counter is not zero, that is, the winning sphere is the specific winning sphere, the number of prize balls different in the number of discharges is set to B (step 7), and 1 is obtained from the value of the specific sphere counter. Is subtracted 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 holes 113a to 113c and the specific winning holes 114a to 114b and discharges the prize balls separately from the specific winning balls. This is to correspond. In step 9, as described above, based on the value of the number of prize balls A and B to be discharged, the number of revolutions of the ball-slicing rotary bodies 7a and 7b for counting and ejecting odd numbers and even numbers is determined as described above, and thereafter, the number of discharges is performed. Then (step 10), the process returns to step 1 after the discharge is completed. In the above example, the operation of the winning ball discharging device 120 is performed by a flow in order to perform the operation via the main control unit. However, when the winning ball detector 125 detects it, the electromagnet 128 is turned “ON” and “OFF”. It is also possible to separately provide a processing mechanism for performing. That is, in the prize ball discharging operation of the present invention, the main control unit causes the winning ball 5a to be detected.
It is configured to be operable upon detection in 5.

[0013]

The pachinko machine of the present invention determines the number of discharged prize balls by judging whether or not the prize balls are specific balls when the prize ball is detected when the prize balls are discharged. In this case, it can be performed by subtracting 1 from the specific sphere counter. Therefore, compared to the conventional discharge control method, the structure can be simplified and the processing can be performed quickly. Furthermore, if the prize ball counting device of the present invention is used, the prize balls can be discharged more quickly.
