DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pachinko ball counting apparatus.

[0002]

2. Description of the Related Art A conventional pachinko ball counting apparatus sequentially counts and discharges a predetermined number of pachinko balls at one time by using a single ball cutting rotary body provided with one ball cutting machine. The number of pachinko balls passing through the ball cutting rotator is counted, or the number of pachinko balls passing directly through the ball cutting rotator is counted. For example, a predetermined number of pachinko balls to be ejected when a prize is won can be rotated according to an ejection command from a control device, and the number of rotations of the ball cutting rotator or the number of pachinko balls passing therethrough is counted. When the predetermined number is reached, the ball cutting rotary body is stopped.

[0003]

As described above, since the conventional pachinko ball counting device has one ball cutting rotary body,
It takes a long time to process a predetermined number of pachinko balls to be counted and discharged based on a discharge command from the control device. Therefore, if the number of winnings is many in a short time, the ejection of pachinko balls will continue forever, and the player will feel uncomfortable. 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. Also, installing a plurality of the same counters as the conventional pachinko ball counter is disadvantageous in terms of cost and control. Therefore, the present invention provides a pachinko ball counting apparatus that solves such a disadvantage.

[0004]

A pachinko ball counting apparatus according to the present invention comprises a ball cutting rotator capable of discharging pachinko balls received from a taxiway in units of an odd number of pachinko balls and an even number of pachinko balls. A ball cutting rotary body that can be discharged as a unit is provided in parallel, and the ball cutting rotary bodies can be independently rotated.

[0005]

According to the pachinko ball counting apparatus of the present invention, the ball cutting rotator capable of discharging the odd-numbered and even-numbered pachinko balls as a unit is provided so as to be independently rotatable. Even if the number is even or odd, discharge is possible.

The pachinko ball counter 1 is connected to a lower end of a meandering guideway 3 (see FIG. 2) connected to a lower part of a gutter (not shown) and receives the pachinko ball 5. The base 4 of the pachinko ball counter 1 is made of synthetic resin through a partition plate 20 and has an H shape in a side view, and a fixed shaft 10 supported at the center by a pair of three-point support members 8. The ball cutting rotator 7a, 7b cuts out (counts and discharges) the odd-numbered and even-numbered pachinko balls 5 while rotating with the weight of the pachinko balls 5.
Is attached. That is, in the present embodiment, the pachinko ball 5 from the taxiway 3 is received, and the odd-numbered ball cutting rotators 7a are set up on the circumference so as to be cut out (counting and discharging) three by three and have a triangular cross section. The ball receiving portion 6a is provided at three places on the partition wall 22a, while the even-numbered ball cutting rotary body 7b is provided with a triangular section wall 2 around it so as to be able to separate two by two.
2b, four ball receiving portions 6b are formed.
a and 7b are independently attached to the fixed shaft 10 so as to be rotatable. The rotation direction of the ball cutting rotator 7a is counterclockwise (FIG. 2), and the ball cutting rotator 7b is formed so as to be clockwise (FIG. 3). Also, the inner peripheral surface of the counter body 1 is provided with protrusions 31a, 3b vertically on the upstream side of the guide path 3 so that the ball cutting rotators 7a, 7b do not come into contact with each other even if they rotate.
The pachinko balls 5 from the taxiway 3 rotate the ball cutting rotators 7a and 7b more smoothly. That is, reverse rotation and rotation inhibition of the ball cutting rotators 7a and 7b are prevented.

The stopping mechanism for the ball cutting rotators 7a and 7b is provided at three places at 120 ° intervals on the periphery of the side wall 23 of the ball cutting rotator 7a, and at 90 degrees on the periphery of the side wall 24 of the ball cutting rotator 7b.
切 Notches 23a, 23b formed at four locations at intervals
And electromagnets 26 respectively inserted into and removed from the notches 23a, 23b.
a, 26b lift rods 27a, 27b with springs 28a, 2b
8b, the stop plates 25a and 25b are connected to each other. That is, the stop plates 25a, 25b are constantly urged by the springs 28a, 28b so as to abut against the side walls of the ball cutting rotators 7a, 7b.
Indicates that the inserted state is maintained in the notches 23a and 23b, and the rotation of the ball cutting rotary bodies 7a and 7b is prohibited. Therefore, the electromagnet 26
When the power is supplied (ON) to the stop plates 25a and 25b, the stop plates 25a and 25b are notched.

Next, the operation of the above configuration will be described with reference to FIGS.
This will be described with reference to FIG. FIG. 4 is a control block diagram. The control device sends signals to the electromagnets according to input signals to discharge the pachinko balls. The input signals include a "winning signal" and a "ball lending signal", and the number of pachinko balls to be discharged is determined in advance in the signal. Therefore, the control device determines the number of rotations n of the three ball cutting rotators 7a at one time based on the signal.
The sum of the rotation speeds n2 of the ball cutting rotator 7b of 1 and 2 discharge numbers (n
1 + n2) is determined to be the minimum rotation speed. For example,
If the number of emissions is 13, n1 is 3, n2 is 2. If the number of emissions is 14, n1 is 2, and n2 is 4. If the number of emissions is 15, n1 is 3, and n2 is 3. The control device determines the number of times of conduction (ON) and non-conduction (OFF) of each electromagnet as n1 and n2. FIG. 5 shows a time chart of "ON" and "OFF" of each electromagnet when the number of discharged pachinko balls is 13. Electromagnet 26a is "ON" (time t1)
Then, the stop plate 25a comes off the notch 23a by overcoming the reaction force of the spring, and the ball cutting rotator 7a starts rotating by its own weight of the pachinko ball in the ball receiving portion. Immediately after that (time t2), the electromagnet is turned "OFF". When the electromagnet is turned "OFF", the stop plate is maintained in a state of being biased by the biasing force of the spring so as to come into contact with the rotating surface of the side wall of the ball cutting rotary member. And the rotation of the ball cutting rotator is prohibited. FIG. 2 shows this state, and three pachinko balls are discharged as shown in the figure. Then, at times t3 and t4 and at times t5 and t6, the same operation as described above is performed. That is, the control device turns on the electromagnet 26a.
By immediately repeating "OFF" three times, 3 times 3 times, a total of 9 pachinko balls are discharged.

On the other hand, the control device also controls the electromagnet 26b at the same time, and turns on at times t1 and t3 to discharge four pachinko balls 2 × 2 times. Thus, the ball cutting rotator 7a counts and discharges nine pachinko balls in the ball cutting rotator 7b, and discharges thirteen in total. Note that the electromagnet is referred to as “O
N], the time interval T1 between times t1 and t3 and between times t3 and t5 is
Even if it is longer than the time until the ball is rotated and discharged while receiving the pachinko ball in the ball receiving part of the ball cutting rotator, even if it is determined to be different for each ball cutting rotator with a different number of pachinko balls in the ball receiving part Although it is good, in this embodiment, the time is set to be longer than the case where the longest time is required for simplicity. Also, turn on the electromagnet
The time T2 from which the ball is turned to "OFF" is within the time from the time when it is turned "ON" (t1, t3, t5) to the time when the next notch arrives, and the ball having a different number of pachinko balls in the ball receiving portion. Shortest time (T2) for cutting rotary body for convenience
Is set uniformly.

Next, FIGS. 6 to 8 show a stopping mechanism of the ball cutting rotary bodies 7a and 7b which are different from the above embodiment. FIGS. 6 and 7 show that the ball cutting rotary bodies 7a and 7b are stopped. FIG. 8 shows a state in which the ball cutting rotator 7a starts rotating. The periphery of the side wall 23 of the ball cutting rotator 7a, which rotates independently, is provided at three places at 120 ° intervals as in the above-described embodiment, and at the periphery of the side wall 24 of the ball cutting rotator 7b at 90 ° intervals. And four notches 23a and 23b are formed respectively, but the shape of the peripheral portion is formed in a substantially parabolic shape from the projecting portion of the notches 23a and 23b to the groove of the next notches 23a and 23b. is there. Therefore, the rotation stop operation of the ball cutting rotators 7a and 7b by the stop plates 25a and 25b can be performed more smoothly. That is, the stop plates 25a and 25b are
The rotation of the ball cutting rotators 7a, 7b is prohibited in the state of contact with the a, 23b, and when the electromagnets 26a, 26b are energized (ON) according to the time chart of FIG. 5 of the embodiment, the springs 28a, 28b are attached. Stop plate 25 overcoming forces
The ball cutting rotators 7a and 7b start rotating by their own weight of the pachinko ball by detaching from the cutouts 23a and 23b (see FIG. 8, but the ball cutting rotator 7b).
Is omitted). Therefore, on the contrary, the electromagnet is de-energized (OF
In the state F), the stop plates 25a, 25b abut against the peripheral edges of the side walls 23, 24 by the urging force of the springs 28a, 28b,
If this state is maintained, the next cutouts 23a, 23b
And the rotation is stopped. That is, the springs 28a, 28
The biasing force of b is smaller than that of the above-described embodiment, so that the attraction force of the electromagnets 26a and 26b is also smaller. The other operations and the like are the same as those in the above-described embodiment, and thus the description thereof will be omitted. Reference numerals 30a and 30b denote abutment plates for guiding the pachinko balls discharged from the ball cutting rotators 7a and 7b downward.

In the above-mentioned embodiment, the ball receiving section is provided with two and three ball cutting rotary bodies in parallel with each other, but more ball cutting rotary bodies are provided and the ball receiving section is provided with more ball cutting rotary bodies. It goes without saying that the number may be configured in another combination. In addition, the ball cutting rotator of the above-described embodiment is rotated by its own weight of the pachinko ball, but it may be directly connected to the pulse motor to control the rotation speed by starting and stopping the pulse motor.
