Description

  The present invention relates to a pachinko gaming machine having a ball feeding mechanism for stably supplying a pachinko ball to a pachinko ball launcher so as to be fired.

In the pachinko gaming machine, the game is executed by driving the pachinko ball launching mechanism and firing the pachinko ball by the player's active handle operation. The pachinko ball launched from the pachinko ball launching mechanism is guided upward while drawing an arc along the rail and released into the game area.
In general pachinko gaming machines other than the enclosed type, pachinko balls stored in an upper receiving tray are guided from the upper receiving tray by a flow-down passage and supplied to a pachinko ball launching mechanism. A ball feeding mechanism is disposed at the lowest position of the downflow passage, that is, at a position adjacent to the pachinko ball launching mechanism. The pachinko balls that flow down the downflow passage are sent to a predetermined position on the rail that is launched by the pachinko ball launching mechanism via the ball feeding mechanism. The ball feeding mechanism feeds pachinko balls one by one onto the rail in synchronization with the launching operation of the pachinko ball launching mechanism. Patent Document 1 is shown as an example of a pachinko gaming machine in which such a conventional ball feeding mechanism is disclosed.
In this type of ball feeding mechanism of a pachinko gaming machine, pachinko balls introduced into the ball feeding mechanism are fed one by one in the rail direction by a swinging motion of a lever. The lever swings by driving a solenoid device arranged in the ball feeding mechanism. In other words, since the solenoid device is excited by being energized, the magnetic attraction force attracts a suction plate made of a ferromagnetic material such as an iron alloy attached to the lever, and the lever swings. ing.
JP 2005-102770 A

By the way, recent pachinko machines have a tendency to design a large game surface particularly from the viewpoint of improving the gameability such as ease of visual recognition, realism and luxury at the time of gaming.
On the other hand, in pachinko halls, the size of the entire pachinko gaming machine cannot be increased because the pachinko gaming machine is attached to a standardized island facility, and as a result, mechanisms other than the gaming surface tend to be more compact. For these reasons, downsizing of the ball feeding mechanism has been conventionally required.
Here, the above-mentioned solenoid device requires the most space among the constituent members disposed in the ball feeding mechanism. However, the size of the solenoid device is not simply reduced because it is directly related to the capacity of the device, that is, the strength of the magnetic attraction force, but the lever is swung in synchronization with the pachinko ball firing speed of the pachinko ball launching mechanism. You must maintain enough ability to move. Therefore, there has been a demand for means for further improving the magnetic attractive force of the solenoid device in such a space-limited ball feed mechanism.
The present invention has been made paying attention to such problems existing in the prior art. The purpose is to be a pachinko that can improve the strength of the magnetic attraction force of the solenoid device that swings the lever for feeding the pachinko ball arranged in the ball feeding mechanism to the launch position. A game machine is provided.

In order to achieve the above object, according to the first aspect of the present invention, the pachinko ball that flows down in the direction of the rail member and the pachinko ball that flows down in the flow passage are temporarily stopped immediately before the rail member and the pachinko ball. A pachinko equipped with a ball feed mechanism that sends balls one by one in the direction of the rail member, and a pachinko ball launch mechanism that launches the pachinko balls sent from the ball feed mechanism toward the game area while guiding the pachinko balls to the rail member In the gaming machine, the ball feeding mechanism includes a solenoid, a magnetic core that is disposed inside the solenoid and that generates a magnetic pole at both ends, and extends from one end of the magnetic core toward both sides and extends around the outer periphery of the solenoid. A solenoid device having a pair of left and right ferromagnetic bodies surrounding and extending toward the other end of the magnetic core, a swing shaft serving as a swing base, and the solenoid A lever having a suction plate attracted by a magnetic force generated by energizing the device and a holding portion for holding a pachinko ball introduced into the ball feeding mechanism is energized by the solenoid device. When the solenoid plate is in the non-excited state, the surface of the suction plate is separated from the end of the leg portion. And swinging between a first position where the pachinko ball introduced into the ball feeding mechanism can be held and a second position where the pachinko ball can flow down in the direction of the rail member. Out of both legs, at least the end of the same leg arranged on the swinging shaft side of the lever is formed with an ear protruding oppositely arranged in a non-contact state with the side end of the suction plate. The door and the gist thereof.

In the configuration as described above, in the pachinko gaming machine, the ball feeding mechanism that sends the pachinko ball to the pachinko ball launching mechanism is configured such that when the pachinko ball flowing down the flow path is introduced from the introduction port, the lever is moved by the solenoid device to the first By swinging between the position and the second position, the pachinko sphere is 1
It flows down toward the rail member one by one.
When the solenoid device is energized and the solenoid device is energized, the surface of the suction plate is attracted to the ends of both legs. When the solenoid device is in a non-excited state, the surface of the suction plate is separated from the end of the leg portion. The lever can swing to take the first and second positions in this excited / non-excited state. The pachinko sphere may be held when the lever is in the first position, and the pachinko sphere may flow down toward the rail member when the lever is in the second position, or vice versa. Note that the suction plate may not be completely adsorbed to the end portions of both legs.
In the solenoid device and the lever having such a relationship, an ear portion is formed at the end portion of the leg portion arranged at least on the swing axis side of the lever so as to face the side end portion of the suction plate in a non-contact state. ing.

By forming such ears, the magnetic attraction force of the solenoid device to the attraction plate is increased. The reason why the magnetic attractive force is increased in this way is assumed as follows.
When the solenoid device is in an excited state, the suction plate is placed in the magnetic field of the solenoid device and is magnetically induced and magnetized. The end of the leg extending from one end of the magnetic core is N
It becomes a magnetic needle of a pole or S pole, and the magnetized suction plate is attracted to the end of the leg. Since the magnetic fluxes repel each other in the air, as shown in FIG. 18A, the magnetic flux to the suction plate tends to spread outward when there is no ear, and the leakage of the magnetic flux into the air is large. However, FIG.
If there is an ear as shown in b), the magnetic flux is guided in the direction of the ear, so that it is difficult to leak outward and the ear is close to the side end of the suction plate (the gap is small), so the magnetic flux It tends to go to the end, and passes through the inside of the suction plate toward the other end of the magnetic core.
Thus, it is considered that the magnetic attraction force can be improved by reducing the leakage of magnetic flux and the proximity of the ear portion to the side end portion of the suction plate. The responsiveness of the suction plate is improved by protruding the ears at the ends. This makes it possible to improve the strength of the magnetic attraction force of the solenoid device against the lever without changing the output of the solenoid device, the lever shape, or the like in a ball feed mechanism with space limitations.

Further, in the invention 2, in addition to the structure of the invention described in claim 1, the side end portion of the suction plate always faces the ear portion formed on the leg portion on the solenoid device side in the swing range of the lever. The gist is that they are arranged.
As a result, the magnetic attractive force at the end of the leg with respect to the suction plate does not weaken in the swing range of the lever, and the suction plate can always respond quickly to the excitation operation of the solenoid device.

Further, in the invention 3, in addition to the structure of the invention described in claim 1 or 2, the surface of the suction plate is attracted to the end of the leg portion by a magnetic attraction force in the excited state of the solenoid device. On the other end side of the magnetic core in the apparatus, a spacing plate for keeping the distance between the two leg portions is disposed, and on the surface of the spacing plate, a rib structure is formed that is flush with the end surface of the leg portion. The gist of this is
The suction plate is sucked as the solenoid device is driven and is attracted to the ends of the two left and right leg portions by a magnetic suction force. Here, if it is supported by only both leg portions at the time of adsorption, the intermediate portion of both leg portions is attracted by the other end of the magnetic core (which also becomes a magnetic pole), so that the suction plate is bent as a whole. Then, there is a possibility that the suction plate may be deformed due to the curvature due to use over time. As a result, the suction plate may fall off the lever with the swing of the lever, or the swinging motion of the lever may not be performed smoothly, causing vibration or wear of the member. In addition, if the end of the leg is not contacted accurately, the magnetic attractive force may be reduced.
On the other hand, in the invention 3, since the suction plate is supported by the rib structure protruding flush with the end face of the leg portion, the suction plate is difficult to be bent and the above problem does not occur.

  In each of the above inventions, since the magnetic attractive force with respect to the suction plate can be improved, the responsiveness of the suction plate is improved by forming the ear portion at the end portion of the leg portion in the solenoid device having the same ability, It is possible to improve the strength of the magnetic attraction force of the solenoid device with respect to the lever without changing the output of the solenoid device, the lever shape, or the like in the ball feed mechanism having a space limitation.

At this time, since the rear of the introduction passage 76 is sealed by the rear wall 61a of the lid 61, the pachinko ball P does not roll off the introduction passage 76 and jump out of the unit 55.
Next, as shown in FIG. 9B and FIG.
The horizontal corner 67, the second inclined portion 78 of the introduction passage 76, and the intersecting corner portion 103 of the vertical wall portion 79 do not fall in the direction of the fall passage 80 but are temporarily held near the entrance of the fall passage 80. Is done. In other words, since the gap between the corner portions 102 and 103 is a narrow path smaller than the diameter of the pachinko ball P, the pachinko ball P is kept waiting at this position when the solenoid device 63 is not excited. In addition, at the standby position, the pressing piece 94 prevents rolling backward.

When the pachinko ball launching device 54 is driven based on the player's operation of the handle 43 in the standby state of the pachinko ball P, the excitation timing of the launching solenoid 58 of the pachinko ball launching device 54 is reached. In synchronization, excitation of the solenoid device 63 of the ball feeding unit 55 is started.
Here, the state of the magnetic field in the excitation state of the solenoid device 63 in the present embodiment will be described based on FIG. The magnetic core 108 is excited by being energized to the solenoid 105, so that the small diameter portion 108a side becomes the N pole and the large diameter portion 108b side becomes the S pole. Since the outer frame 111 is fixed to the small-diameter portion 108a, the outer frame 111 is also magnetized, and eventually both the hanging portions 113, 11
The lower end position of 4 is an N pole. The metal piece 70 disposed in such a magnetic field is magnetized by magnetic induction, and the metal piece 70 is attracted to the lower end surfaces of both the hanging portions 113 and 114.
At this time, an ear portion 115 is formed on the left hanging portion 113, and the magnetic flux flows from the ear portion 115 from the side end surface of the metal piece 70 along the metal piece 70 to the S pole (large diameter portion 108b). Will be. Therefore, the metal piece 7 has a magnetic attractive force stronger than that of the case where the ear 115 is not formed.
0 is adsorbed.

As the metal piece 70 is attracted to the solenoid device 63, the lever 65 swings upward with the position of the bearing 66 as a base. That is, it is separated from the small protrusion 73. Along with this displacement, the space between the two corners 102 and 103 holding the pachinko ball P opens, and the pachinko ball P falls in the direction of the fall passage 80 (the state shown in FIGS. 9C and 10C). . The fallen pachinko ball P is guided by the inclined surface 71 a and sent out on the firing rail 53.
Since the excitation time of the solenoid device 63 is very short, the lever 65 swings downward by its own weight when the excitation is released, and is again supported by the small protrusion 73 in FIGS. 9A and 10A. Return to. The pachinko ball P following the fallen pachinko ball P is held at the standby position by the lever 65 and the both corners 102 and 103 of the introduction passage 76 which have returned to the original state. The following will be repeated below.

By configuring as described above, the present embodiment has the following effects.
(1) The lever 65 swings upward when the metal piece 70 is attracted by the solenoid device 63. At this time, the metal piece 70 is disposed at a position sandwiched between the pair of ear portions 115 of the hanging portion 113. Therefore, the magnetic attraction force acts more strongly than the solenoid device of the same type in which the ear portion 115 is not formed, and the lever 65 swings upward earlier when the solenoid device 63 is excited. It will be. As a result, it is possible to accurately synchronize with the operation of the pachinko ball launcher 54.
Further, even if the excitation timing of the launching solenoid 58 of the pachinko ball launching device 54 is set to be shorter (that is, the interval between the pachinko ball launches is shortened), the strong magnetic attraction force is exerted so quickly. It is possible to control to follow the timing.
Furthermore, even when it is unavoidable to reduce the internal space in the design of the ball feeding unit, even if the rated output is inevitably reduced due to the adoption of a smaller solenoid device, such an ear is used. By forming the portion, it is possible to improve the magnetic attraction force to the attraction plate as much as possible.
(2) Since the lower surface of the solenoid device 63 to which the metal piece 70 is attracted is formed so that the lower end surfaces of both the hanging portions 113 and 114 and the lower top surfaces of the ring-shaped rib 109 and the linear rib 110 are flush with each other, The metal piece 70 is not only the lower end surface of the both hanging portions 113 and 114 but also the ribs 109 and 110.
Will also abut. Therefore, the metal piece 70 is not easily deformed even when used over time, and the metal piece 70 is detached from the lever 65, the swinging motion of the lever 65 is not smoothly performed, and the member is vibrated or worn. There is no possibility that various problems such as a decrease in magnetic attraction force occur when the piece 70 does not accurately contact the end of the leg.
Further, as a result of the bending strength of the second flange 107 being improved by the ring-shaped rib 109 and the linear rib 110, the rigidity of the solenoid device 63 itself is improved.

The present invention can be implemented with the following modifications.
In the above embodiment, the ear 115 is formed only on the left hanging part 113, but FIG.
), The ear 115 may be formed on the right hanging part 114 as shown in FIG. This is because the magnetic attractive force is improved even in this case. However, in this case, the effect of improving the magnetic attractive force is not so great as compared with the left hanging portion 113 that always faces the end of the metal piece 70. Of course, the ear may be elongated so as to always face the end of the metal piece 70. In that case, an improvement in magnetic attraction force equivalent to that of the ear 115 of the left hanging part 113 can be expected.
In the above embodiment, the pair of ears 115 is formed at the lower end of the hanging part 113 and the metal piece 70 is sandwiched from the front and rear, but the number of the ears 115 is not a pair but only one of the front and back. It does not matter. In short, it is only necessary that the ear 115 extends to the position of the side end surface of the metal piece 70.

As shown in FIGS. 16A and 16B, the width of the metal piece 70 is made wider than the inner space of the ear portion 115, and the notch portion 120 is formed at a position where it interferes with the ear portion 115 of the metal piece 70. You may make it form. If the end portion of the ear portion 115 is surrounded from the three sides by the side end surface of the metal piece 70 in this way, the amount of the side end surface of the metal piece 70 adjacent to the ear portion 115 increases, so that the magnetic portion The suction force will be improved.
As shown in FIGS. 17A and 17B, an extended portion 121 that is bent and extended upward at the tip of the rectangular metal piece 70 is formed, and this is formed on the outer surface of the hanging portion 114. Extension part 12
1 may be set along. If comprised in this way, since the magnetic flux which flows into the metal piece 70 will increase, a magnetic attraction force will improve further.
-The shape, thickness, length, etc. of the ear | edge part 115 can be changed suitably.
-The shape of the ring-shaped rib 109 and the linear rib 110 can be changed suitably.
-In the above embodiment, it was applied to a so-called first type pachinko machine with a starter,
The type of pachinko machine is not particularly limited. It can also be applied to a sealed pachinko machine.
In addition, it is free to implement in a mode that does not depart from the spirit of the present invention.
