Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention relates to a pachinko game machine in which a plurality of rotating members are rotated when a batted ball enters a specific winning hole, and a pattern illustrated on the rotating members when the rotating members are stopped. Depending on the combination of the above, or the state in which the game ball passes through the rotating member, the opening time of a specific winning hole may be prolonged, or the winning chances of the ball may be increased by repeating the opening, or the ball may pass through the rotating member. The present invention relates to an electric accessory device for a pachinko game machine that changes the route of a batted ball.

0002

[Prior Art] In a conventional electric accessory device for a pachinko game machine of this type, a rotating member is provided on each of a plurality of shafts rotating on the same axis at a position visible from the front of the game member. The shaft of each rotating member and the motor corresponding to each rotary disk were connected by a driving means such as a gear mechanism, and each rotating member was driven and stopped by each motor.

0003

[Problems to be Solved by the Invention] However, in such an electric accessory device for a pachinko game machine, it is necessary to control the rotation and stop of each rotating member independently. On the other hand, since a motor has only one rotating shaft, a motor is required for each rotating member, so a plurality of motors are required. As for the number of motors that can be installed in close proximity to the same center, up to two motors can be installed with their axes facing each other, but if it is more than that, it is impossible to install them, and a drive means such as a gear mechanism is used to rotate the motors. Since it is necessary to transmit the rotational speed to the rotating member, there is a drawback that the mechanism using such a driving means becomes complicated.

[0004] The complication of such a mechanism requires space, which is not only disadvantageous in terms of space, but also has the disadvantage of increasing costs. Furthermore, since there are a plurality of motors, at least space for the plurality of motors is required, and there are also disadvantages such as further aggravating the disadvantage in terms of space. In a pachinko game machine, parts such as a gutter for guiding the game ball and mechanisms for various operations by the game ball passing through the gutter are arranged on the back side of the game board, and the increase in space is caused by the pachinko game machine design is difficult.

[0005] In order to solve the above-mentioned drawbacks of the conventional electric accessory devices for pachinko gaming machines, the present invention makes it possible to provide a plurality of shafts on the same axis by making at least one shaft hollow. This eliminates the need for multiple power transmission parts, simplifies the mechanism, and reduces the number of parts to improve reliability and reduce costs.In addition, by reducing the installation space, it is easier to secure space. The purpose is to

[0006]

[Means for Solving the Problems] The electric accessory device for a pachinko game machine of the present invention is intended to achieve the above-mentioned object, and the means thereof is to provide a plurality of stators in the axial direction with respect to the same axis. In addition, a multi-shaft motor in which a rotor is provided for each stator, one or more of the rotor shafts is made hollow and the shaft of the other rotor is inserted into this, and each shaft of the multi-shaft motor is connected to a pachinko game machine. A rotary member serving as an accessory is attached, and each rotary member is driven to rotate differently by the multi-axis motor, so that each rotary member is rotated about a concentric axis.

[0007]

[Operation] In the electric accessory device for a pachinko game machine of the present invention, a plurality of stators are provided on the same axis, and the shaft of one rotor provided corresponding to each stator is connected to the other stator. In order to pass through the correspondingly provided hollow shaft of the rotor, this motor can be provided with a plurality of shafts on the same axis, each shaft being independently controllable, and these stators, Since the rotor can be installed with a small gap in the axial direction, the motor can be made smaller.

Since a rotating member is installed on each of the plurality of shafts, each rotating member can be individually controlled by its own rotor, and a drive mechanism for transmitting the rotation of the motor is not required. This, coupled with the miniaturization of the motor, makes it possible to reduce the installation space on the back side of the game board surface, and also to eliminate the need for a mechanism for driving the rotating member.

[0009]

[Embodiment] Next, an example of implementing the present invention will be described with reference to FIGS. 1 to 5. Figure 1 is a front view of the entire pachinko machine.
On the game board surface 1, there is a big prize opening 3 for electric accessories 2, and a windmill 4.
, a tulip accessory 5, and a starting port 6 are provided. The starting openings 6 are provided in three places, and when a ball hits any of them, the opening/closing piece 3a of the big winning opening 3 opens for one second, increasing the chance of winning the ball. When a player wins a prize, a predetermined number of game balls are delivered to the receiving tray.

On the back side of the electric accessory 2, there is a pulse motor A to be described later, an upper rotary disk 8 and a lower rotary disk 9 as rotating members rotated by the pulse motor A, and a prize winning hole 3. A guide board 10 for guiding the game ball B toward the upper rotary board 8 is provided.

The above-mentioned pulse motor A has the same axis, and a plurality of tooth-like teeth formed of a highly conductive plate on the side closer to the lower rotary disk 9 and protruding in the axial direction on the inner circumferential surface thereof. A stator 11 has a coil wound around a convex portion to pass a pulsed current,
A similar stator 12 is also fixedly attached within the case 13 on the remote side.

The shaft 15 of the rotor 14, which is composed of a magnet that is magnetized so that magnetic poles are formed at regular intervals facing the stator 12, is connected to the bearing 16 of the case 13 on the side remote from the lower rotating disk 9. A hollow shaft 18 of a rotor 17 similar to the rotor 14 facing the stator 11 is
The shaft 15 is inserted through the washer 19, and bearings 20 and 21 are provided between the shaft 15 and the hollow shaft 18 so that the hollow shaft 18 can freely rotate with respect to the shaft 15. is supported by a bearing 22 of the case 13.

Therefore, in this pulse motor A, by changing the number of pulses and pulse intervals supplied to the coils of the respective stators 11 and 12, the number of rotations, the rotation speed, the rotation direction, etc. of the shaft 15 and the hollow shaft 18 can be changed. It is possible to control the stopping position, etc.

Fixed to the shaft 15 of the motor A, the shaft 1
The upper rotary disk 8 rotated by the player 5 is formed in the shape of a curved conical surface with a medium height, and a drop hole 8a large enough to allow the game ball B to fall is bored in a part of its outer periphery. The game ball B that entered the big prize opening 3 and fell onto the guide board 10 rolls along the boundary surface between the guide board 10 and the upper rotary board 8 while the upper rotary board 8 is rotating. It looks like this.

A hollow shaft 18 is disposed below the upper rotary disc 8 so that the lower rotary disc 9 rotates in accordance with the rotation of the hollow shaft 18.
The lower rotary disk 9 is formed into a medium-height conical surface so that the game ball B that falls onto the lower rotary disk 9 moves toward the outer peripheral edge of the lower rotary disk 9.

[0016]Furthermore, the lower rotary disk 9 has a part along the periphery where the game ball B falls into one place, so that
A guide groove 9a is formed to guide the game ball B to a drop hole 9b that allows the game ball B to fall to the lower surface, and a plurality of recesses 9c are formed so that the game ball B can be transferred into any of the guide grooves 9a.

[0017] On the outer periphery of this lower rotary disk 9, there is a retaining recess 9c.
A partition wall 23 is erected to prevent the game ball B transferred into the ball from slipping out from the retention recess 9c to the outside, and a prize ball gutter 24 is formed at one place on the back side of the partition wall 23. The game ball B, which is provided with the notch 23a and moves along the partition wall 23 after entering the retention recess 9c,
When reaching the notch 23a, the game ball B passes through the notch 23a and is sent out from the prize ball gutter 24.

Also, while the upper rotary disk 8 and the lower rotary disk 9 are rotating, when the drop hole 8a of the upper rotary disk 8 and the guide groove 9a of the lower rotary disk 9 match, the game ball B falls from the drop hole 8a. Then,
The game ball B enters the guide groove 9a, and when the specific prize opening 23b provided at one place on the bottom of the partition wall 23 and the drop hole 9b match, the game ball B in the guide groove 9a falls into the drop hole. 9b
Enter the specific winning opening 23b through the special winning opening 23b.
When passing through the specific winning gutter 25 that is continuous with the above, a detection switch 26 provided in a part of the specific winning gutter 25 is turned on.

Next, the operation of this transmission accessory device for a pachinko game machine will be explained. When the batted ball enters the starting hole 6, the big winning hole 3 of the power transmission accessory 2 opens for only one second by a conventionally known method, and the chance of the hit ball winning in the big winning hole 3 during this one second is increased. At the same time, by entering the starting port 6, a pulse current is supplied to the coils of the stators 11 and 12 of the pulse motor A, and a driving force is generated between the coils of the stators 11 and 12 of the pulse motor A, and the driving force is generated between the rotors 17 and 14 and the magnets of the rotors 17 and 14. 15. The hollow shaft 18 starts rotating.

[0020] As described above, the batted ball that enters the big winning hole 3 falls onto the guide plate 10, but since the upper rotary plate 8 is formed into a curved conical surface with a medium height, The guide plate 10 does not climb up to the top, but rolls along the boundary between the rotating upper rotary disk 8 and the non-rotating guide disk 10. and,
When the falling hole 8a reaches the position of the rolling game ball B due to the rotation of the upper rotary disk 8, the rolling game ball B is
It moves into the drop hole 8a, and from this drop hole 8a the lower rotary plate 9
fall on top. Since the lower rotary disk 9 is also formed into a medium-height conical surface, the game ball B that has fallen onto the lower rotary disk 9 rolls toward the outer periphery of the lower rotary disk 9 and transfers into the retention recess 9c.

[0021] The game ball B that has moved into the retention recess 9c is moved to the partition wall 23 because the lower rotary disk 9 is also rotating as described above.
It moves while rolling along the notch 2 of the partition wall 23.
When the position 3a is reached, the prize ball gutter 24 is inserted from this notch 23a.
The game balls B discharged from the prize ball gutter 24 perform a winning operation such as sending out a certain number of prize balls to the saucer 7.

However, when the drop hole 8a of the upper rotary disk 8 and the guide groove 9a of the lower rotary disk 9 coincide, the game ball B falls into the drop hole 8.
If it falls from the guide groove 9a, this game ball B will fall from the guide groove 9a.
It falls into the special prize gutter 25 through the drop hole 9b, enters the special prize winning hole 23b, and turns on the detection switch 26. By turning on the detection switch 26, the probability of winning or the number of prize balls is increased by repeating the opening of the big prize opening 3 several times.

In this embodiment, the pulse motor A shown in FIG. 6 can be used instead of the pulse motor A described above. The pulse motor A in FIG. 6 has a stator 11
, 12 are housed in two cases 13a and 13b, and rotors 17, 1 corresponding to the stators 11, 12 are housed in two cases 13a and 13b.
The shaft 15 of one of the rotors 14 in the case 1 is inserted into the hollow shaft 18 of the other rotor 17, and the hollow shaft 18 is inserted into the hollow shaft 18 of the other rotor 17.
The shaft 15 is supported by the bearings 30 and 31 of the case 13.
It is supported by bearings 32 and 33 of b.

One bearing 32 of the shaft 15 has a convex flange 32a.
One bearing 31 of the hollow shaft 18 is provided with a recess 31a into which the convex flange 32a is fitted. Then, as shown by the two-dot chain line in the figure, the shaft 15 is connected to the hollow shaft 1.
8, insert the convex flange 32a of the bearing 32 into the recess 3 of the bearing 31.
1a, the case 13b is attached to the case 13a, and the two pulse motors in the cases 13a and 13b are integrated, and the operation, function, and effect of this motor are different from the motor A of the previous embodiment. do not have.

Next, other embodiments of the present invention are shown in FIGS. 7 to 10.
I will explain about it. As shown in FIG. 10, the pulse motor A used in this embodiment is mounted on a mounting plate 40 to the game board surface 1.
and the holding case 41, there are three stators 42, 43,
44 is fixed. The shaft 50 of the rotor 46 corresponding to the stator 42 is inserted into the hollow shaft 51 of the rotor 47 corresponding to the stator 43, and the hollow shaft 51 is inserted into the hollow shaft 52 of the rotor 48 corresponding to the stator 44.

The opposite side of the shaft 50 from the rotor 47 is rotatably supported by a bearing 53 provided on the mounting plate 40, and the opposite side of the shaft 50 is a bearing 55 of the hollow shaft 51 inserted through a washer 54. 56, and the hollow shaft 51 is supported by a washer 57.
The hollow shaft 52 inserted through the holding case 41 is supported by bearings 58 and 59, and the hollow shaft 52 is supported by a bearing 60 of the holding case 41.

A rotary disk 62 having a ball 61 similar to the game ball B attached to the board surface 62a is fixed to the outermost hollow shaft 52 so as to rotate integrally with the hollow shaft 52, and the inner hollow shaft 51 The rotating board 63 is arranged so that the board surface 63a depicting a plurality of different patterns rotates around the inner periphery of the board surface 62a.
is fixed, and furthermore, on the shaft 50 is a board surface 64a on which the same symbols as the board surface 62a are drawn in a different arrangement from the board surface 63a.
A rotary disk 64 is fixed to rotate around the inner circumference of the disk surface 63a.

In this embodiment, a disk is attached that rotates together with the rotors 46 to 48 and detects the rotational position, and a display that can be read by a sensor is drawn on this disk, thereby indicating that the rotation Boards 62, 63, 6
4 rotational position can be detected.

In this embodiment, as in the previous embodiment, when a ball hits the starting port 6 in FIG.
Different pulsed currents flow through the stators 42, 43, 44 of the rotors 46, 47, 48, which start rotating and stop independently at the end of the pulsed currents. In this way, a win is determined by the alignment of the balls 61 on the stopped rotating disk 62 and the symbols on the rotating disks 63, 64, and the prize balls determined by the alignment are sent to the saucer 7.

The probability of such a hit can be determined in advance by detecting the rotational positions of the rotary disks 62, 63, 64 and by sending pulses to each stator 42, 43, 44 from the arithmetic control circuit. Further, by adding colors or light-emitting members to the above-mentioned rotating disk, it is possible to make the game even more enjoyable.

[0031]

[Effects of the Invention] As mentioned above, the present invention can be used as a motor.
One of the shafts of two or more rotors is made into a hollow shaft, and the other shaft is inserted into this, thereby making it possible to form an integrated motor that can take out two or more kinds of rotations using the hollow shaft and the shaft. Therefore, in an electric accessory device for a pachinko game machine that requires individual control of a plurality of rotary disks on the same axis, there is no need to separately install a motor for each rotary disk.

Further, there is no need for a driving means such as a gear mechanism that rotates the rotary disk and the motor in conjunction with each other. This not only simplifies the entire device and reduces costs, but also reduces the probability of failure, increases reliability, and increases operating rates.

Furthermore, the overall space of the device can be saved, as a driving means such as a gear mechanism is not required, and only one motor is required, making it easy to secure installation space. In addition, by providing bearings between the hollow shafts and between the shafts and the hollow shafts, it is possible to achieve effects such as being able to eliminate elements that make rotation unsmooth such as vibrations.
