TECHNICAL FIELD OF THE INVENTION
The game ball counter of the present invention is installed in a passage of game balls to be lent to a player called a "lending ball" on the back of a card reader type game table called a so-called CR machine and counts the number of game balls. The present invention relates to a game ball counter.
[0002]
[Prior art]
Conventionally, in a card reader type gaming table called a so-called CR machine, the path of the game ball on the back side is the same as the path of the game ball to be lent to a player called a “lending ball” and a prize is won during the game. The mainstream was a gaming table where the path of the prize ball paid out to the player when there was no distinction was made.
[0003]
However, the path of the "lending ball" to be lent to the player is originally positioned as a facility of a game arcade, and the path of the prize ball to be paid out to the player when a prize is won is one mechanism in each gaming table. However, from the viewpoint of the convenience of the configuration of the gaming table, it is the current situation that both paths are integrated into one.
[0004]
The reason why both passages are unified in many game consoles is from the viewpoint of the convenience in configuration of the game console and the problem of price. First, in terms of the structure of the game console, separating the two passages means that two separate passages are provided separately on the back surface of the narrow game console, and the game ball is located somewhere on the passage. Means that one counter must be provided for each path.
[0005]
The path of the game balls may have the width of the game balls, but the counter needs a mechanism for dropping the game balls at regular intervals and counting them because it is necessary to accurately count the game balls. Conventional counters focus on counting prize balls rather than counting "lending balls" to be lent to players, so the ability to quickly count a large number of prize balls paid out during a jackpot. Therefore, the shape of the power source for driving the counting mechanism also becomes large, and as a result, the entire counter must be large.
[0006]
In addition, the mechanism of the counter is such that the prize ball passage is separated into two lines in order to increase the speed of paying out prize balls, and a sensor in the counter is provided with a mechanism for alternately dropping game balls and counting them alternately. It tends to be larger and more complex. For this reason, separating the passage of the "lending ball" to be lent to the player and the ball passage of the prize ball, and installing one conventional counter in each of the ball passages is necessary in a small space on the back of the gaming table. Is becoming more and more difficult.
[0007]
Further, as shown in FIG. 13B, the conventional counter having a large and complicated mechanism is becoming expensive in terms of price. This is one of the major factors that raises the price of the stand itself. Therefore, the idea of unifying the vibrating ball passage and using a single counter for the prize ball as well as the counter for counting "lending balls" was dominant.
[0008]
[Problems to be solved by the invention]
However, as described above, it is better to separate the passage of the “rental ball” and the passage of the prize ball. As long as the player plays the game in compliance with the law, sharing the above two passages for convenience will not cause a real problem, but if the player performs an illegal operation, the responsibility is held. In order to clarify the above, it is necessary that the two paths are clearly distinguished, and the game balls passing through the two paths must be properly counted by different counters.
[0009]
However, since the conventional game ball counter has a complicated and bulky mechanism, it is impossible to install two counters on the back of the game console where various devices must be installed, and the cost of the counter itself is high. As described above, the installation cost of the gaming table itself is increased by installing two units. So, I sought to find out more about what's wrong.
[0010]
Obviously, the problem lies in trying to count the "lending ball" and the prize ball to be paid out to the player with a counter of the same ability. In other words, the "lending ball" paid out to the player is very small, so it is enough to accurately count about 25 balls at a time, whereas the prize ball is tens of times that at the time of a big hit. The quantity must be counted accurately.
[0011]
Therefore, if it is necessary to separate the passage between the "lending ball" to be paid out to the player and the prize ball passage, the conventional counter for counting the prize ball for the counter installed in the "lending ball" passage is a chicken. Obviously it is unreasonable to have a sword to tear. In other words, the counter installed in the passage of the “rental ball” only needs to have an ability to accurately count a small amount of game balls.
[0012]
In short, what is needed is a counter dedicated to "lending balls" that can accurately count a small number of gaming balls and has a very small overall volume. Accordingly, it is an object of the present invention to develop a game ball counter that can be operated accurately with a simple mechanism, can be provided at a low cost, and has as small a volume as possible.
[0013]
[Means for Solving the Problems]
The present invention has been made to solve the above problems, and the gist thereof is as follows. That is, a ball passage housing in which a ball passage serving as a passage of a game ball is formed, a sensor storage portion for storing a sensor in which a sensing hole through which a game ball passes is positioned below the ball passage, and the ball passage housing. A body provided with a motor chamber for storing a motor adjacent to the body and a stopper chamber for storing a stopper capable of holding a game ball in a locked state, a cover covering the main body, and a receiving plate for the shaft of the stopper, In the stopper composed of the upper stopper and the lower stopper which are integrally rotated by the motor via a gear, the tapered surface of the upper stopper for retaining and retaining the game ball and the taper surface of the lower stopper for retaining and retaining the game ball are provided. It is formed at a position shifted by 180 °, and the vertical end of the upper stopper through which the game ball passes and the vertical stopper of the lower stopper through which the game ball passes The end is formed at a position shifted by 180 °, a part of the ball passage housing is cut out so that the tapered surface of the upper stopper projects into the ball passage, and the tapered surface of the lower stopper is A part of the ball passage housing is cut out so as to protrude into the ball passage, and the game ball that has been retained and retained by the taper surface of the upper stopper protruding into the ball passage is rotated by rotation of the entire stopper. When the vertical end of the upper stopper is located at the position of the game ball, the hold of the game ball is released, and when the game ball falls, the tapered surface of the lower stopper protrudes into the ball passage at the drop point. Is positioned, the game ball is temporarily locked and held on the taper surface of the lower stopper, and the vertical end of the lower stopper is positioned at the position of the game ball by rotation of the entire stopper. At the same time, the holding of the game ball is released and the game ball falls, and at the same time, the next game ball is locked and held by the tapered surface of the upper stopper protruding into the ball passage, and the game ball that has dropped first is in the ball passage. A game ball counter characterized in that the passage of the game ball is accurately counted by passing through the sensing hole of the sensor located immediately below the game ball.

The receiving plate 9 is screwed and fixed to a lower portion of the rear plate 6 as seen in FIG.
[0028]
When the cover 10 is screwed and fixed to the main body 1, the upper part on the left side of the ball passage housing 2 is set as the right end, the upper part on the right side of the side plate 13 of the cover 10 is set as the left end, and the upper part on the back of the front plate 12 of the cover 10 is set as the right end. A motor chamber 4 is formed having a front end, a bottom surface of the top plate 11 of the cover 10 as an upper end, and a top surface of the partition wall 5 as a lower end. There is no partition at the rear of the motor chamber 4 and it is open.
[0029]
The lower left side of the ball passage housing 2 is the right end, the lower right side of the side plate 13 of the cover 10 is the left end, the lower back of the front plate 12 of the cover 10 is the front end, and the upper surface of the bottom plate 14 of the cover 10 is received.

[0030]
In the motor chamber 4, a motor 16 is screwed on the upper surface of the partition 5 by a fixing plate 17. The shaft 16a of the motor 16 projects below the shaft hole 5a of the partition wall 5. The cord of the motor 16 extends outward from the notch 13a of the side plate 13 of the cover 10 as shown in FIGS. The motor 16 in this embodiment is a stepping motor.
[0031]
In the stopper chamber 8, a shaft hole 18b is formed at the center of a shaft 18a protruding from the upper surface of the gear 18, and the shaft hole 18b is closely fitted to the shaft 16a of the motor 16, and the rotation of the motor 16 is introduce. The shaft 18a is in a state of being loosely fitted in the shaft hole 5a.
[0032]
19 is a gear that meshes with the gear 18 and is integrally fixed to the stopper S. The stopper S has a substantially disc-shaped upper stopper 20, a lower stopper 21, and a shaft 22 formed integrally with each other, and the gear 19 is integrally fixed around the shaft 22 on the upper surface of the upper stopper 20.
[0033]
A shaft hole 22a is formed in the center of the shaft 22, and another shaft 23 is rotatably inserted therethrough. The upper end of the shaft 23 is fitted and fixed in the shaft hole 5 b of the partition wall 5, and the lower end is fitted and fixed in the shaft hole 9 a of the receiving plate 9. Therefore, the stopper S is rotatably mounted around the shaft 23.
[0034]
9a and 9b show details of the stopper S. As described above, the stopper S has the shaft 22, the upper stopper 20, the lower stopper 21, and the gear 19 integrally formed. A tapered surface 20a connected to the upper surface and a tapered surface 20b connected to the lower surface are formed in at least half of the circumferential end of the upper stopper 20 of a substantially disk shape, and the radius of this portion is longer than that of the remaining portion. .
[0035]
The portion of the upper stopper 20 other than the tapered surface 20a and the tapered surface 20b is a vertical end 20c having a circumferential end formed vertically, and the radius of this portion is smaller than that of the tapered surface 20a and the tapered surface 20b. It is short. There are two places where the tapered surface 20a, the tapered surface 20b and the vertical end 20c are connected on the circumference, one of which changes smoothly, and the other changes abruptly to form a step 20d. Therefore, when the first game ball locked and held on the tapered surface 20a of the upper stopper 20 falls, it smoothly flows down while abutting on the tapered surface 20a.
[0036]
The lower stopper 21 having substantially the same diameter as the upper stopper 20 has a tapered surface 21a connected to the upper surface in at least half of the circumferential end portion, and has a longer radius at this portion than at the remaining portion. The portion other than the tapered surface 21a is a vertical end 21b having a circumferential end formed vertically, and the radius of this portion is shorter than that of the tapered surface 21a. There are two portions where the tapered surface 21a and the vertical end 21b are connected, one of which changes smoothly, and the other changes abruptly to form a step 21c.
[0037]
The tapered surfaces 20a and 20b of the upper stopper 20 and the tapered surface 21a of the lower stopper 21 are out of phase by approximately 180 ° as shown in FIGS. 9a, 9b, 10b, 11b and 12b, and as a result, the vertical end 20c and the vertical end 21b are also out of phase by approximately 180 °. Also, the phase of the steps 20d and 21c is shifted by approximately 180 °.
[0038]
As is clear from FIGS. 10a and 12a, when the tapered surfaces 20a and 20b of the upper stopper are located on the side of the spherical passage 3, the tapered surfaces 20a and 20b have a longer radius and project into the spherical passage 3 from the slit 2a. At this time, in the lower stopper 21, the vertical end 21b having a short radius is located on the side of the ball passage 3, so that the vertical end 21b does not protrude into the ball passage 3 from the slit 2b.
[0039]
11A, when the tapered surface 21a of the lower stopper is located on the side of the ball passage 3, the tapered surface 21a has a longer circumferential radius and protrudes into the ball passage 3 from the slit 2b. At this time, since the vertical end 20c having a short radius is located on the side of the ball passage 3 in the upper stopper 20, the vertical end 20c does not project into the ball passage 3 from the slit 2a.
[0040]
Hereinafter, the operation of the present embodiment will be described with reference to the drawings.
In FIG. 10A, it is assumed that the game balls Q1, Q2, Q3, and Q4 continuously fall into the ball passage 3 from above. FIG. 10a shows an initial state of the present embodiment. In this initial state, the state of the stopper S is always a portion close to the step 20d of the tapered surfaces 20a and 20b of the upper stopper 20 as shown in FIGS. 10a and 10b. Is projected into the ball passage 3, and the game ball Q1, which is the leading ball, is locked and held on the tapered surface 20a.
[0041]
In this state, when the stopper S rotates clockwise (in the direction of the arrow) in FIG. 10B, the tapered surface 20a rotates clockwise while the game ball Q1 is locked and held, and when rotated about 180 °, FIGS. 11A and 11B. As shown in FIG. 7, the vertical end 20c having a short radius is located on the ball passage 3 side, and the game ball Q1 is released from the locked state and dropped.
[0042]
However, at this time, the tapered surface 21a is located on the ball passage 3 side of the lower stopper 21, and since the tapered surface 21a has a long radius, the tapered surface 21a protrudes into the ball passage 3 from the slit 2b, and the game ball Q1 is on the tapered surface 21a. Is suspended. When the first game ball Q1 is locked and held, all subsequent game balls Q2, Q3 and Q4 are also locked and held.
[0043]
With the rotation of the motor 16, the stopper S rotates clockwise (in the direction of the arrow in FIG. 11B) while holding the game ball Q1 on the tapered surface 21a of the lower stopper 21 and about 180 ° from the state of FIGS. 11A and 11B. When rotated, the state is as shown in FIGS. 12A and 12B. At this time, the tapered surface 20a having a long radius of the upper stopper 20 protrudes into the ball passage 3, and the game ball Q2 (and subsequent game balls Q3, Q4,...) Is locked and held on the tapered surface 20a.
[0044]
In this state, the vertical end 21b having a short radius is located on the ball passage 3 side of the lower stopper 21, and the game ball Q1 is released from the suspended state, and the ball passage 3 as shown in FIG. It falls further and passes through the sensing hole 24a of the sensor 24 mounted immediately below the ball passage 3.
[0045]
The sensor 24 is an electronic sensor. When the game ball Q1 passes through the sensing hole 24a, the inductance of a coil (not shown) surrounding the sensing hole 24a changes, and a pulse signal is output (known in the art). Technology). Thereby, the passage of the game ball Q1 is counted (it is naturally possible to use a mechanical sensor).
[0046]
The game ball Q1 counted by the sensor 24 passes through the hole 15d immediately below the sensing hole 24a, falls downward, and is lent to the player as a "lending ball". The following game balls Q2 (and the following game balls Q3, Q4,...) Are locked by the taper surface 20a of the upper stopper when the game balls Q1 are counted in the sensing holes 24a, as is apparent from FIGS. It is on hold.
[0047]
At this time, if the configuration is such that the game balls Q1, Q2, Q3,... Continuously pass through the sensing hole 24a, the counting capability of the sensor 24 becomes unstable and causes malfunction, but in this embodiment, As described above, the next game ball Q2 is in the lock pending state until the previous game ball Q1 has completely passed through the sensing hole 24a.
[0048]
That is, the game balls Q1, Q2, Q3,... Are not divided continuously but individually, and pass through the sensing hole 24a at regular intervals, so that the counting ability of the sensor 24 is stable and no malfunction occurs. . Also, since the game balls Q1, Q2, Q3,... Fall one by one without being continuous, no extra impact is applied to the mechanisms located below the present embodiment.
[0049]
When the game balls Q1 have been counted and completely dropped, the above process is repeated for the game balls Q2, Q3,. The reason why the motor 16 is a stepping motor in this embodiment is that the number of game balls can be counted on the motor side by programming the necessary number of balls in the motor 16 in advance.
[0050]
This has the effect that the counting becomes more accurate, and at the same time, the motor 16 automatically stops when the required number of balls has been counted, so that there is no need to incorporate a mechanism for stopping the motor 16. It is. Therefore, when the above effects are not expected, the present invention can naturally be realized even if the motor 16 is a normal motor.
[0051]
The function of the tapered surface 20b continuous with the lower surface of the upper stopper 20 is, for example, that the upper portion of the game ball Q1 locked and held on the tapered surface 21a of the lower stopper 21 in the state of FIG. This is to prevent the game ball Q1 from being caught between the upper stopper 20 and the lower stopper 21 when it comes into contact with the lower stopper 20.
[0052]
FIGS. 13a and 13b show a comparison between the size of the counter A of the present invention (the above embodiment) and the size of the conventional counter B at the same scale. The conventional counter B shown in FIG. 13B is a further improvement of a prize ball dispensing device (Patent No. 2957446) filed by the applicant of the present invention, and has a state-of-the-art mechanism as a prize ball counter. And the smallest size.
[0053]
That is, in order to quickly count a large number of prize balls, the ball passage 27 is formed into two sections, and the motor 26 rotates the toroidal core T (referred to as a "ball receiving member" in the specification of Japanese Patent No. 2957446). Are alternately dropped on the sensor 25 and counted. The motor 26 is also a stepping motor, and the counting is accurate by combining the counting on the motor 26 and the counting by the sensor 25 as in the above embodiment of the present invention.
[0054]
In the conventional counter B, in order to quickly count a large number of prize balls, the two toy balls Q1, Q2 falling from the ball passages 27, 27 are forcibly added by the toroidal core T and quickly. Since the motor 26 needs to be moved and dropped on the sensor 25, a motor having a large output is required correspondingly, and as a result, the size of the motor 26 must be large.
[0055]
On the other hand, in the counter A of the present invention (the above embodiment), since the game ball Q1 is merely put on the upper stopper 20 or the lower stopper 21 of the stopper S and rotated until it falls naturally, the output of the motor 16 Is sufficient to add the rotational frictional force of the game ball Q1 to the output for rotating the stopper S, and the size of the motor 16 can be reduced accordingly.
[0056]
The size of the whole counter is determined on the basis of the motor size. However, when comparing the motor 16 of the counter A of the present invention (the above-mentioned embodiment) with the motor 26 of the conventional counter B, the diameter is substantially equal. The difference is almost double. Thus, as can be seen in a comparison of FIGS. 13a and 13b, the counter A is reduced in size to nearly one-half of the counter B and in volume by a factor of three or less. .
[0057]
【The invention's effect】
Since the counter of the present invention uses a simplified mechanism, the size of the counter itself can be reduced to about one-half in size and about one-third or less in volume compared to a conventional counter. Could be reduced. Conventionally, it was impossible to install two counters on the back of the game console mainly due to space issues, and it was unavoidable to use one counter to count "lending balls" and prize balls, and as a result, " Although there was only one passage between the “lending ball” and the prize ball, the game ball counter of the present invention should be able to install the counter of the present invention in addition to the conventional counter on the back of the game console without space constraints It becomes possible to perform the counting of the “lending ball” and the prize ball separately, and it becomes possible to clearly separate the passage between the “lending ball” and the prize ball.
[0058]
In the embodiment using the stepping motor as the motor in the counter of the present invention, the game balls can be counted on the motor side, and the effect that the counting becomes more accurate occurs, and at the same time, the number of necessary balls is counted. The motor stops automatically when the operation is completed, so that there is no need to incorporate a mechanism for stopping the motor.
[0059]
Since the counter of the present invention uses a simple mechanism in which the upper stopper and the lower stopper are simultaneously operated by one motor, the number of failures is small, and the manufacturing cost is extremely low as compared with the conventional counter. Even if the game ball counter of the present invention is mounted in addition to the conventional counter, the manufacturing cost of the game console itself is hardly affected.
[0060]
In the counter according to the present invention, the game balls that have finished counting do not drop continuously from the counter and fall one by one, so that no extra impact is given to the mechanisms located below the counter. .
[0061]
In the counter of the present invention, since the taper surface is also provided on the lower surface of the upper stopper, the game ball suspended and held on the taper surface of the lower stopper is caught between the upper stopper and the lower stopper. Therefore, there is no fear of affecting the driving state of the counter.

Claims (1)

A ball passage housing in which a ball passage serving as a passage of a game ball is formed, and a sensor storage unit for storing a sensor in which a sensing hole through which a game ball passes is positioned below the ball passage; A motor chamber for storing a motor adjacent to the main body, a main body provided with a stopper chamber for storing a stopper capable of holding a game ball in a locked state, a cover for covering the main body, and a stopper plate for a shaft of the stopper, In the stopper composed of an upper stopper and a lower stopper which are integrally rotated by the motor via a gear, a taper surface of the upper stopper for retaining and retaining the game ball and a taper surface of the lower stopper for retaining and retaining the game ball are provided. The vertical end of the upper stopper, which is formed at a position shifted by 180 °, and through which the game ball passes, and the vertical end of the lower stopper, through which the game ball passes A part of the ball passage housing is cut out so that the tapered surface of the upper stopper projects into the ball passage, and the tapered surface of the lower stopper is formed in the ball passage. A part of the ball passage housing is cut out so as to protrude therefrom, and the game ball held and retained by the taper surface of the upper stopper protruding into the ball passage is rotated by rotation of the stopper as a whole. When the vertical end of the upper stopper is located at the position of the upper stopper, the hold of the game ball is released, and when the game ball falls, the tapered surface of the lower stopper projecting to the ball passage at the drop point is located. As a result, the game ball is temporarily locked and held on the taper surface of the lower stopper, and the vertical end of the lower stopper is located at the position of the game ball by rotation of the entire stopper. Although the locking pending game ball is released the recreation ball falls next game ball simultaneously obtained by forming so as to be engaging suspended by the tapered surface of the upper stopper which protrudes to the ball passage, the upper stopper taper The two portions where the surface and the vertical end are connected on the circumference are formed so that one is formed to change smoothly and the other is formed to have a step so as to switch rapidly, and is connected to the taper surface of the upper stopper. The game balls that have been stopped are configured to flow smoothly, and the game balls that have fallen first pass through the sensing holes of the sensor located immediately below the ball passage, so that the passage of the game balls is accurately counted. A game ball counter characterized by the following.
