Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ball feeding device used for a pachinko machine, an arrangement ball game machine, a rocking ball game machine, and the like.

[0002]

2. Description of the Related Art A game ball is launched by tilting a firing hammer by a rotating firing cam, and a game ball is supplied to a firing position by a small handle attached to the firing hammer by tilting the firing hammer. Ball supply method is pachinko machine.
It is already known in JP-A-35586. Also, the device for counting game balls operates a ball receiver with a solenoid,
This is a system for detecting whether or not a game ball exists inside a ball receiver, and is used in an arrangement ball game machine and a jiyayan ball game machine.

[0003]

However, in the conventional launching device of a pachinko machine, the launching hammer fires a game ball due to the engagement / disengagement relationship between the firing cam provided on the motor side and the roller arm provided on the firing hammer. At the moment, the firing hammer returns to its original position with the spring attached to the firing hammer, so when it returns, the firing hammer bounces. It is well known that two vibration isolating rubbers are provided to minimize the bounce, and the rubber itself deteriorates and deforms as the operation of the pachinko machine increases. The bounce of the hammer increases with the progress of deformation and deterioration of the vibration-isolating rubber.
As an example, hitting the ball at 86 in FIG. 8 causes the ball feeding lever to vibrate, and the ball is fed (hereinafter referred to as a duck, which is dropped one by one in addition to the recess formed inside the structure). 8 is operated, and one ball is sent out.
Therefore, when sending out the next game ball to the firing point, when the launching of the hammer starts tilting, the accessory small handle activates the ball feeding device to send out the game ball to the firing point, and the result firing point has two pieces. The disadvantage is that the game balls are lined up. Also, the counting of the game balls sometimes causes the duck to be actuated by the vibration of the hammer and counts two places where one should be one.

As described above, in the conventional pachinko machine, even if the driving state of the game ball launching apparatus and the operating state of the ball feeding apparatus are properly adjusted, the positioning vibration isolating rubber,
Due to the deterioration of the shock absorbing rubber, the tension spring, or the like, a stable and stable supply of the game balls to the launch point cannot be obtained, and the good flight state of the game balls cannot be maintained. This is because the launch hammer hits the game ball replenished with the bounce a little, that is, when the rebound is replenished, the timing of the bounced tip coincides with the ball and the ball contacts the ball and the ball jumps out in the firing direction. However, at the time of actual firing, the timing does not match, and the game ball is not stably stopped, which results in poor ball flight. For this adjustment, it is necessary to replace the anti-vibration rubber and the shock-absorbing rubber, adjust the position of the anti-vibration rubber, and adjust the angle of the small handle that activates the ball feed lever at the amusement arcade. It is a disadvantage. In addition, a skilled technician also needs to make initial adjustments at a production plant.

[0005] More specifically, referring to FIG.
1 and a ball feeding device 80 for firing game balls 97. A firing motor 92 is attached to the firing device 81, the firing motor 92 has a rotating shaft 95, and a firing cam is mounted on the rotating shaft 95. 85 is provided, and the rotating shaft 95 rotates clockwise when the game ball 21 is fired. Launcher 81
Is attached to a firing dial (not shown), and a winding pulley 93 is attached to the firing dial with a mandrel (not shown). The winding pulley 93 is connected to a firing force adjuster 90 by a tension spring 89 and a wire 96, and the firing force adjuster 90 is provided for fine adjustment of the firing force. Turning the firing dial counterclockwise as shown in FIG. 8 starts firing, and turning the dial further increases the firing intensity and extends the flight distance. A duck 82 is attached to the ball feeding device 80, and a ball feeding lever 86 is provided at a position where the ball feeding lever 86 contacts the bottom surface of the duck 82. The launching device 81 is provided with a launching hammer 83, which is urged in the direction of arrow R by a pulling spring 89, and the launching hammer 83 is attached to the positioning vibration isolating rubber 8.
8 and the impact absorbing rubber 91 are fixed at a predetermined angle. With the rotation of the firing cam 85, the apex is the firing hammer 83
When the firing arm 83 reaches the roller arm 94, the firing hammer 83 is rotated in the direction of arrow D to a firing hammer 84 indicated by a dotted line, and when the firing cam 85 is further rotated, the roller arm 94 is disengaged from the apex of the firing cam 85. The game ball 97 is repelled in the direction of the arrow P by the urged spring 89 to fly.

[0006] A small handle 87 is attached to the firing hammer 83, and when the firing hammer 83 moves, the small handle 87 is moved.
Actuates the ball feed lever 86 and accordingly the duck 82
When the shooting hammer 83 repels in the direction of arrow P, the game ball 97 added to the duck 82 is supplied to a launch point (not shown). The firing operation can be continuously performed by sequentially supplying the game balls 97 to the firing point by repeating this operation. At this time, when the firing hammer 83 rebounds and returns, the bouncing of the firing hammer 83 is suppressed by the positioning anti-vibration rubber 88 and the shock absorbing rubber 91. If the adjustment is inadequate, the bounce of the launching hammer 83 will increase, and the small handle 87 will activate the duck 82 to send out the game ball 97 again.
Next, the firing cam 85 rotates, and the firing hammer 83 moves in the direction of arrow D to send out the next game ball 97. After all, when the two game balls 97 are fired side by side at the firing point, they naturally go to the desired position. The game ball 97 does not fly. Further, if the ball feeding device 80 is provided on the back side of the upper plate (not shown), the upper plate itself can be opened and closed, and there are variations and play at the fulcrum, and there is an unstable element that cannot be completely fixed. There is also a drawback that the engagement and disengagement relationship between the handle 86 and the small handle 87 is not at a fixed position.

[0007] The above is a drawback that has been hitherto in the past. This is because a player who has no luck in the game raises or lowers the upper plate with annoyance, causing distortion and the timing of feeding is incorrect. Unless the adjustment is made, two game balls are sent or the ball is hit slightly to make the game ball jump out in the firing direction. At the time of actual firing, it is bad if the game ball sits badly. It is an object of the present invention to provide a launching device that does not need to be installed. Next, when the player is hitting automatically (biting and fixing a foreign object on the firing control lever and connecting the firing dial and the glass frame with a wire or the like) and the game ball is exhausted, the player plays the game. When the player leaves the gaming machine, the firing operation does not stop unless the automatic beating is stopped. This means that the firing operation does not stop unless the power of the gaming machine is turned off or the handle is returned.

Next, counting game balls fired by a general pachinko machine is not usually considered. For example, a game machine with a special first-class electric accessory (hereinafter referred to as a first-class pachinko machine) wins a jackpot and a special winning prize is opened to obtain a special prize for the game, and obtain a large number of game balls as prize balls. , The opening time of the special winning opening is approximately 6 seconds for 10 balls in a single opening, and the opening of the special winning opening 16 times is possible.
60 winning balls are obtained. An interval timer is provided between each opening. If the interval from the occurrence of the jackpot to the closing of the 16th winning port is 100 balls per minute and the interval timer is 4 seconds, the interval timer is large. The total opening time of the winning opening is 16 × 6 = 96 seconds, the interval timer is 15 × 4 = 60 seconds, the opening time of the winning opening and the interval timer are added, and 60 + 96 = 156 seconds, the number of winning balls in the winning opening. Is 15 and the total number paid out is 1
60 × 15 = 2400 balls, 156 × 100 = 160 = 260 game balls to be shot, and the total number of balls obtained is 2400−260 = 2140, but all open large winning openings are won. This is the case when there is a game ball that does not enter the open special winning opening. If the number of game balls that could not win the special winning opening during this jackpot is large, the total number of obtained balls will decrease, that is, if the number of balls is constant at 2400 and the number of hits is 260 and the time increases, This results in an increase of 260 pieces, and a decrease in the total number of balls. Without the above-mentioned data on nail adjustment, which is the starting point of amusement arcade management, it is impossible to grasp and take countermeasures without the above-mentioned data. Note that the above calculation shows a case where only the large winning opening is considered without looking at other winning openings. The present invention has been made in view of the above-mentioned drawbacks, and this solution will be described below.

[0009]

Means for Solving the Problems As set forth in claim 1,
A plate on which the game board can be detachably fixed, a firing rail is fixed below the plate, a game ball is supplied to the firing point of the firing rail, and the game ball supplied to the firing rail is provided on the game board. In a ball feeding device configured to be capable of being fired and supplying a game ball to a firing point, a mounting portion is provided on the plate in the vicinity of the firing point of the firing rail, and the mounting portion is provided with a game ball by a driving source of the firing device. A ball feeding device comprising a game ball introduction port and a discharge port provided with an interlocking portion for leading a ball to an outlet, the ball feeding apparatus being detachably attached. By providing the ball feeding device on the plate, the launching device and the ball feeding device are completely fixed to the game board in a straight line with the game board, and stable ball feeding can be performed. There was also a method that could feed balls by attaching a ball feeding device to the plate so as to cover the firing rail, but there was a disadvantage that it was difficult to clean the firing rail, so it was provided behind the upper plate so that the firing rail could be cleaned easily. Invented.

However, when provided on the back side of the upper plate, the upper plate itself can be opened and closed, and there are manufacturing variations and play at the fulcrum, which has been an unstable factor. A conventional plate is attached to an inner frame and fixes a game board to the inner frame. The plate is provided with a thickness suitable for the game board, and the inside thereof is hollow and is not used effectively. A recess is provided near the firing point of the plate to which the ball feeder is attached, and the ball feeder is detachably mounted in the recess, and the firing rail is cleaned in the same manner as before, so that it can be fixed stably. Since it is fixed, ball feeding will not go out of order during operation. Alternatively, the ball feeding device may be attached to the back of the plate without providing the concave portion. In this case, since the firing rail is easily cleaned, this method is also excellent.

Next, a method of operating the ball feeding device is as described in claim 2, wherein the power transmission device is attached to a rotating shaft of a driving device provided in the launching device. A ball feeding device for operating a feeding device. By providing the ball feeding device on the plate side, smooth power transmission can be easily performed. When a ball feeding device is provided on an upper plate and ball feeding is operated by a combination of levers as in the related art (see FIG. 8), a position where the lever is operated, a position where the lever hits, a position where the lever hits the ball feeding device, and the like are determined. The sliding position of the lever and the contact position of the lever shaft are deviated due to wear of the lever shaft. This is because the ball feeding device is provided on the plate side as described in the driving device, that is, the shaft of the motor. By operating the ball feeding device with the belt, the position is not deviated and the ball feeding device becomes stable. Next, at the timing of firing and feeding which are particularly regarded as important, as shown in claim 3, in the ball feeding device according to claim 1 or 2, the rotation axis of the driving device and the ball feeding device are linked. A ball feeding device, wherein the launch and the replenishment of game balls are synchronized, and the timing is set so that the launch can be performed when the game balls are stably stopped on the launch rail.

As described above, when the lever is used, the timing of contact with the lever is delayed due to wear of the sliding surface of the lever. This has to be adjusted from time to time by changing the shape of the other parts that hit the lever. If the interval is mistakenly reduced and the interval is reduced, the operation timing is advanced, and if the interval is increased, the operation timing is delayed. In order to solve this drawback, operating the ball feeding device with a shaft or belt from the motor shaft uses a gear for a shaft drive and a timing belt for a belt. By doing so, it is possible to smoothly and stably feed balls in synchronization with nature. In addition to this, it is also possible to use a wire whose transmission direction is free. If the motor shaft and the rotating body of the ball feeding device are connected by this wire, the structure can be further simplified. In addition, a method of rotating the ball feeding device by a motor or a rotary solenoid is also conceivable, and the device may be operated in electrical synchronization with the firing motor.

As a countermeasure for the occurrence of a failure or the like in the power transmission device, as described in claim 4, in a ball feeding device for replenishing game balls to the firing point of the firing rail, the ball feeding device transfers the game balls. A ball feeding device provided with a game ball detection device for detecting passage of the game ball when the ball is sent. It is conceivable that the ball cannot be fed due to a failure of the power transmission device.If a game ball detection device is provided, the ball feed device is used when the game ball detection device does not detect a game ball despite the fact that it promotes firing. Can be regarded as a failure. Also, if a game ball detection device is provided, when a player interrupts the game by automatically hitting and there is no game ball in the ball feeding device, the firing device will be moved uselessly after a certain period of time. It is possible to stop the launching device by providing the game ball detecting device when it is not possible to detect the ball. As the next example of how to use the game ball detection device, it is possible to stop the motor at a fixed point because the launch and the ball feeding are synchronized, and considering the case where this firing is stopped during firing, the game ball can be used. If energization of the motor is stopped at the time of detection, the load is not applied to the motor when restarting since the firing hammer has finished firing. With the above configuration, the motor is rotated by about half and the firing cam of the motor shaft is at a position where it starts to contact the roller arm of the firing hammer.

Next, the provision of the game ball detecting device can be effectively used in a game machine for counting the number of shots such as an arrangement ball game machine and a jiya ball game machine. This means that a frame device can be shared between an arrangement ball game machine, a jingyan ball game machine, and the like and a pachinko machine. Counting the number of shooting balls mentioned in the above defect, counting the number of shooting balls with the game ball detection device of the first kind pachinko machine and seeing how many balls could not be entered with the number of winning balls and the number of shooting balls at the time of a big hit Therefore, if the total number of acquired balls is small, the player is dissatisfied, and as a guide for good gaming machines and bad gaming machines, it is determined by this value, that is, the difference between the number of winnings and the total number of shots . In designing pachinko machines such as pachinko machines of the first kind that have a prize opening that can be opened in time, the position of the game nail can be determined by relying on this difference value. Can be used as a reference for firm data on nail adjustment. Unlike the conventionally known method of detecting a game ball by a pause detection method such as pressing with a game ball or a duck type, the game ball detection device employs a constant velocity passage method, so that a game ball lacking or Even a deformed game ball can be detected and ball clogging does not occur.

In a conventional pause detection method such as pressing a game ball with a game ball detection device, when a game ball detection switch or a game ball detection sensor is used for detecting a game ball in a method of detecting a game ball, Since the game ball detection switch or the game ball detection sensor has a limitation on a duty interval which is a detection range, sometimes a missing game ball or a deformed game ball cannot be detected. In the duck type, the movement is a reciprocating movement, so excessive counting due to bouncing occurs.In the duck type, there is a method driven by a solenoid, but the wear is severe and replacement of parts called ducks and replacement of the ball feeder itself are required. Sometimes they are forced. Speaking of why the ducks are worn, as the operation of the solenoid can be understood by anyone, when the solenoid is energized and de-energized, a shock like a hammer hit is generated by the solenoid, and the impact is given to the duck and the game ball The inertia is several times the weight of the game ball. The shock generated by this inertia and the shock of the solenoid itself result in the wear of all the components linked to the solenoid. As described above, in the detection of the game ball, the constant velocity passage type provides the most excellent effect as compared with other game ball detection methods.

According to a fifth aspect of the present invention, in the method of mounting a ball feeding device, in the ball feeding device according to any one of the first to third aspects, the mounting portion is a concave portion, and a pin is provided in the concave portion and the ball is provided. A ball feeding device, wherein a hole for the pin is also provided in the feeding device, and the ball feeding device is loaded on the pin. A pin of the same quality as the plate is provided at a specific position in the concave portion of the plate, and this pin is tapered, and a cylinder with a tapered hole is provided in the ball feeder in the same shape as the ball feeder. If the taper hole of the ball feeding device and the taper pin on the plate side are pushed into communication with each other, stable fixing can be easily performed. Although there is a possibility that the ball feeding device may fall off due to vibration, a stopper for preventing falling off may be provided, and if a lid is provided on the plate side, the falling off can be prevented.

According to the ball feeding device 38 described above, since the launching motor 34 and the ball feeding device 38 rotate at the same rotation speed by having the structure shown in claims 1 to 3, smooth synchronization can be obtained. The conventional drawback described in the problem to be solved by the invention, such as sending two game balls by the bounce of the launch hammer 83, does not occur at all. This means that the vibration of the ball feed transmitted to the firing handle 19 which the player dislikes is eliminated, and the vibration noise due to the vibration is eliminated, so that the player can be immersed in the game, and thus the sales of the pachinko parlor This has the effect of leading to an increase.

According to a fourth aspect of the present invention, when the gamer frequently says that the launch handle 19 is to be bitten by a foreign object in a gesture that is often performed by a player, and that the firing handle 19 is released. When the ball detection device 43 does not detect the game ball 24 after the set time because there is no game ball 24 on the upper plate 15, the firing device 27 is stopped to prevent useless empty shots. It also has an effect. To operate again, once the firing handle is returned in the counterclockwise direction and the firing position is returned again, the firing operation can be performed. Further, when a game board is changed to a game machine having a break such as an arrangement ball game machine or a jing ball game machine, the number of shots can be counted, so that the game content can be easily changed. Since the fixed point operation of the firing motor can be stopped, a smooth start can be performed. Since the ball feeding device can be easily attached and detached as described in claim 5, even if there is a failure in the ball feeding device, the ball feeding device can be easily replaced simply by replacing the ball feeding device. As described above, the effect of the present invention has not been seen in the past, and it can be said that the present invention is excellent because it can be handled easily and smoothly in both a production factory and a game arcade.
