  In the first place, the momentum of the game ball launched by the launch device of the pachinko machine is generally strong in the situation of jumping to the game area through the guidance area, weakened in the situation of going backward from the game area to the guidance area as a return ball, and further returning to the ball It becomes the weakest at the time when the reversal is prevented (blocked) by the prevention device. Therefore, in order for the game ball at the time when reversion is prevented to move to the center of the game area again, some means is required to positively repel the game ball, for example, to play the game ball. It was a thing.

However, the above-described prior art has not been provided with a special configuration in which the return ball is actively fired toward the game area. Therefore, the action that can be performed on the return ball by such a configuration is merely to prevent or prevent the return, and the game ball that is generally prevented from returning is compared with the possibility of winning because the game ball is directly below that position. It was forced to flow down to the lower area. Therefore, since the player has to give up his expectation for winning the winning game ball, there is a problem that the interest is lowered.
Incidentally, although the technique of the above-mentioned patent document 3 certainly performs the action of rebounding the return ball, this is a guide region while maintaining the posture of blocking the return ball at the normal time by preventing the prevention piece portion of the ball return prevention device. In order not to obstruct the passage of game balls that are driven into the game area from the game, this is merely an operational effect associated with the formation of the elastic band plate. Actually, even the invention of Patent Document 3 does not correspond to a structure having a configuration in which the return ball is positively ejected to the game area.

  Accordingly, the present invention provides a gaming machine equipped with a ball return prevention device that solves the problems in the conventional ball return prevention device for gaming machines and can guide the return ball again in a direction in which the winning potential of the gaming area is high. Is an issue.

In order to achieve the above object, a gaming machine equipped with a ball return prevention device of the present invention is used to play a game ball launched by a launching device from a launching port of a guidance region to a game region to be used in a game region. A gaming machine provided with a ball return prevention device in the vicinity of the pop-out opening for preventing a game ball that has once jumped out to the game area from returning to the guide area, The first feature is that it is provided with a return ball-stopping bullet piece that stops the game ball that is placed in the game area and returns to the outlet from the game area and that also operates itself to repel the game ball.
In addition to the first feature, the gaming machine provided with the ball return prevention device of the present invention is based on a return detection means for detecting that the game ball has returned to the outlet, and detection by the return detection means. The second feature is that it has an instantaneous displacement means that momentarily displaces and moves the return ball stopping bullet.
In addition to the second feature described above, the gaming machine equipped with the ball return prevention device of the present invention has a momentary displacement means having a piezoelectric element, and using the reverse piezoelectric effect of the piezoelectric element, The third feature is to operate the piece.

According to the gaming machine provided with the ball return prevention device according to claim 1, when the game ball that has once jumped out of the guide area from the outlet to the game area returns to the outlet again, the ball return prevention apparatus is provided. The returned ball stopping bullet piece stops the game ball and replays the game ball.
Therefore, according to the gaming machine equipped with the ball return prevention device according to claim 1, without returning the game ball returning from the game area to the jumping opening to the guidance area by the return ball stopping bullet, It can be rebounded greatly in the direction of the game area, and it can be led again to an area where there is a high possibility of winning in the game area.

According to the gaming machine provided with the ball return prevention device according to claim 2, in addition to the effect by the configuration according to claim 1, the reverse detection means for detecting that the game ball has returned to the outlet. And a momentary displacement means for operating the return ball stopping bullet piece by momentarily displacing based on the detection by the return detection means, so that the detection means detects when the game ball returns backward Then, the instantaneous displacement means is operated. As a result, the momentary displacement means is momentarily displaced, whereby the return ball stop bullet is operated and the game ball that has returned backward is released.
Therefore, according to the gaming machine equipped with the ball return prevention device according to claim 2, the game ball that has returned backward is surely detected by the return detection means, and the return ball stopping bullet is quickly operated to remove the game ball. The game ball that has been able to be fired and returned back to the outlet can be led to an area where there is a high possibility of winning in the game area in a timely and effective manner.

  Further, according to the gaming machine provided with the ball return prevention device according to claim 3, in addition to the effect by the configuration according to claim 2, the instantaneous displacement means has a piezoelectric element, and the reverse piezoelectricity of the piezoelectric element. Since the return ball stopping bullet piece is operated using the effect, the return ball stopping bullet piece can be operated quickly using the instantaneous deformation of the piezoelectric element, It is possible to lead to an area having a high possibility of winning a game area in a timely and effective manner.

FIG. 7 shows a state in which the game ball that has returned backwards is returned and the ball-stopping bullet is repelled.

First, referring to FIG. 1, at the center of a game board 1 of a pachinko gaming machine, a game area 2 is formed into a substantially circular area by being divided from the outside with an outer rail 3 and an inner rail 4 as walls. Near the center of the game area 2 is provided a center case 5 that can display the symbols and the like, and below it is provided a start winning device 6 that gives an opportunity to start the changes of the symbols and the like. Game elements such as a gate 7 through which game balls pass, a normal winning device 8, a big winning device 9, an out port 10, a windmill 11, and a nail 12 shown only partially are provided.
A game ball Q launched by a launching device (not shown) passes through a guide area 13 formed between the outer rail 3 and the inner rail 4 and jumps out from the outlet 14 to the game area 2 to be used in the game. Ball game ball Q flows down the game board 2 from the upper part to the lower side of the game area 2 and wins the start winning device 6, the normal winning device 8, and the big winning device 9. Enter the outlet 10. When the winning devices 6, 8, and 9 are awarded, a predetermined reward such as paying out game balls can be received.
A frame lamp 15 is provided outside the game area 2 on the left and right shoulders of the game board 1.

A ball return prevention device 100 according to the present invention is disposed in the vicinity of the pop-out opening 14 in the upper left part of the game area 2.
2 to 7, the ball return prevention device 100 operates the swinging body 110 provided with the return ball stopping bullets 111 and the return ball stopping bullets 111 via the swinging body 110. There is an instantaneous displacement means 120 and a reverse detection means 130 for detecting that the game ball Q has returned to the outlet 14.

The rocking body 110 has a base portion 112 that is fixedly attached to the proximal end side of the return ball stopping bullet 111 in addition to the return ball stopping bullet 111.
The return ball stop bullet 111 is a member disposed at the outlet 14 and is formed of an elastic strip piece made of metal or the like, the base end side is cantilevered, and the upper end side is free. When the return ball stop bullet piece 111 is disposed at the pop-out port 14, it can be appropriately bent and adjusted in the middle so as to ensure an appropriate position with respect to the pop-out port 14.
The tip of the return ball stopping bullet 111 has a length that can reach and come into contact with the outward step 3a formed on the outer rail 3 corresponding to the position of the outlet 14. In some cases, the return ball stop bullets 111 are not in contact with the outward stepped portion 3a of the outer rail 3 but are held slightly apart.

  The base portion 112 includes a bearing portion 112c formed with a guide groove 112a and a shaft hole 112b for defining the mounting posture of the return ball stop bullet piece 111, and the return ball stop bullet piece 111 attached to the base portion 112. And a weight portion 112d for maintaining a standing posture in a normal state. The shaft nail 112e is inserted into the shaft hole 112b of the bearing portion 112c and is fixed to the game board 1, so that the swinging body 110 is swingably held around the shaft nail 112e. The bearing 112c is formed with an eccentric cross section with respect to the center of the shaft hole 112b.

The instantaneous displacement means 120 for operating the return ball stop bullet 111 has a piezoelectric element 121, a transmission member 122, a spring 123, and an advance / retreat member 124 as main components, and in addition, a housing portion 125 and a sliding guide member 126. is doing.
The housing part 125 includes a main body 125b provided with a flange 125a having an attachment hole for attachment to the game board 1, and a cover 125d provided with a notch 125c on the upper surface.
The piezoelectric element 121 is accommodated in the housing part 125, and the lower surface of the piezoelectric element 121 is fixed to the floor surface in the housing part 125 by bonding or the like. The base 122a of the transmission member 122 is placed in contact with the upper surface of the piezoelectric element 121, and the cover 125d is put on the protrusion shaft 122b of the transmission member 122 and the cover 125d is put on. The upper portion of the shaft portion 122b protrudes upward from the notch 125c of the cover 125d. At this time, the spring 123 is interposed between the cover 125 d and the base 122 a of the transmission member 122, and makes the transmission member 122 contact the piezoelectric element 121.
The protruding shaft portion 122 b of the transmission member 122 protruding from the housing portion 125 is fixed integrally with the fixing base portion 124 a of the advance / retreat member 124.
The advancing / retracting member 124 is normally in a retracted position downward, and when the advance / retreat member 124 is advanced upward, the advancing / retreating member 124 comes into contact with the bearing 112c of the base body 112 of the rocking body 110 to rotate it. That is, the gap between the left end portion of the bearing portion 112c and the inner rail 4 is set to be smaller than the thickness dimension of the advance / retreat member 124 at the time of detecting the reverse movement shown in FIG. The clearance is expanded to the thickness dimension of the advance / retreat member 124 as the advance / retreat member 124 advances upward. When the advancing / retreating member 124 pushes the left end of the bearing 112c formed in the eccentric shape as described above in the right direction, the bearing 112c rotates in the clockwise direction around the shaft nail 112e. is there.
The return ball stopping bullet 111 is operated together with the base 112 by the rotation of the bearing 112c.
The displacement of the instantaneous displacement means 120 is an instantaneous displacement because it uses the inverse piezoelectric effect of the piezoelectric element 121, and the operation of the return ball stop bullet 111 is also an instantaneous operation.
The sliding guide member 126 is attached to the outer surface of the inner rail 4 slightly above the housing portion 125 to guide the forward / backward posture of the advance / retreat member 124 from the back. The advancing / retracting member 124 is regulated by the sliding guide member 126 and the notch 125c of the housing portion 125 so as not to cause lateral blur in the drawing.

The reverse detection means 130 is provided on the outward step portion 3 a of the outer rail 3 corresponding to the position of the pop-out port 14. In this embodiment, the reverse detection means 130 is configured as a reverse detection switch, and the detection switch main body 131 is built in the frame lamp 15 outside the outer rail 3 (see FIGS. 5 to 7), and the detection front end. A portion 132 is arranged to protrude from the outward stepped portion 3 a of the outer rail 3.
When the game ball Q comes back and hits the return ball stop bullet piece 111 and pushes it to the left (counterclockwise in the drawing), the upper end side of the return ball stop bullet piece 111 reaches the outward stepped portion 3a. Displaces and comes into contact with the detection tip 132. As a result, the return detection means 130 detects the return of the game ball Q, and the detection signal is sent to a control unit of a pachinko machine (not shown). A voltage is applied via

The operation of the configuration of the first embodiment described above will be described.
A game ball Q launched from a launching device (not shown) passes through the guide region 13 and jumps out from the launch port 14 into the game region 2 while slightly deforming the return ball stopping bullet 111 formed of an elastic band plate.
FIG. 5 shows a state in which the game ball is still on the way of returning, that is, a state in which the ball return prevention device is not receiving any action of the game ball Q. In this state, due to the action of the weight portion 112d of the base portion 112 of the rocking body 110, the return ball stop bullet piece 111 is almost closed from the outward step portion 3a of the outer rail 3 in the state where it is separated. Is in a state.
As a result of the game ball Q that has once jumped into the game area 2 hitting the nail 12 or the like, the game ball Q hits the return ball stop bullet 111 again when the game ball Q hits the nail 12 again, and this moves backward (counterclockwise on the drawing). ) To obtain a state as shown in FIGS. At this time, the tip of the return ball stopping bullet 111 hits the detection tip 132 of the reverse detection means 130, and the switch is turned on. The detection signal of the detection means 130 is transmitted to the control unit, and the control unit applies a voltage to the piezoelectric element 121 via the booster circuit.
The piezoelectric element 121 is instantaneously deformed (stretched) by the reverse piezoelectric effect by applying a voltage, and the transmission member 122 is instantaneously displaced against the spring 123. As a result, the advancing / retracting member 124 advances upward, and the bearing portion 112c of the base portion 112 of the rocking body 110 is instantaneously rotated clockwise about the shaft nail 112e. As a result, the return ball stop bullet piece 111 instantaneously moves forward (clockwise in the drawing) and repels the game ball Q (FIGS. 3 and 7). As a result, the game ball Q returns to the center of the game area 2 again.
When the application of voltage to the piezoelectric element 121 is stopped, the piezoelectric element 121 returns to the original state, the transmission member 122 is displaced downward by the biasing force of the spring 123, and the advance / retreat member 124 is retracted downward to return to the original state. Return to position. Therefore, the return ball stopping bullet 111 returns to the original position by the weight 112d (FIG. 5).

By providing the ball return prevention device 100 of the first embodiment, it is possible to give a player an expectation of winning a return ball that could not have been expected to win, and this contributes to an improvement in interest.
More specifically, in the conventional apparatus, the game ball Q, which is prevented from backflow of the ball, substantially flows only from the position immediately below the ball return prevention device to the region D in FIG. In the trajectory leading to the D region, the possibility that the game ball Q wins the start winning device 6 which is an important winning opening is extremely low.
On the other hand, in the ball return prevention device 100 according to the first embodiment, the game ball Q that has been prevented from going back to the outlet 14 is further rebounded by the return ball stop bullet piece 111, thereby The trajectory of the returned game ball Q is a trajectory that flows down from the A area or B area to the C area in FIG. Therefore, the possibility of winning the start winning device 6 is increased, and even with such a return ball, the player can continue to have a favorable expectation of winning.

A second embodiment of the present invention will be described with reference to FIGS.
FIG. 8 is a front view of the game board of the pachinko gaming machine according to the second embodiment, and FIG. 9 is an exploded perspective view of the ball return prevention device. 10 to 12 are enlarged views of the vicinity of the ball return prevention device of the game board. FIG. 10 shows a state in which the game ball is in the process of returning. FIG. 11 shows the game ball that has returned in the reverse direction. FIG. 12 shows a state in which the game ball that has returned backwards has been returned and the ball-stopping bullets have rebounded.
Note that in the pachinko gaming machine of the second embodiment, members and elements that perform the same functions as those of the pachinko gaming machine of the first embodiment are denoted by the same reference numerals and description thereof is omitted.
In the second embodiment, as in the case of the first embodiment, the ball return prevention device 200 is disposed in the vicinity of the outlet 14 at the upper left of the game area 2.
The ball return prevention device 200 includes a rocking body 210, an instantaneous displacement means 220, a reverse return detection means 230, and a stopper member 240.

The oscillating body 210 includes a return ball stopping bullet member 211, a base body 212, an instantaneous displacement unit 220, and a reverse detection unit 230.
The return ball stopping bullet piece 211 has the same configuration as the return ball stopping bullet piece 111 in the pachinko machine of the first embodiment.
The base portion 212 is also substantially the same as the base portion 112 in the pachinko machine of the first embodiment, and a bearing portion 212c formed with a guide groove 212a and a shaft hole 212b for defining the mounting posture of the return ball stopping bullet 211. And a weight part 212d for maintaining the return ball stopping bullet member 211 attached to the base part 212 in an upright posture in a normal state. A shaft nail similar to the shaft nail 112e shown in FIG. 4 is inserted into the shaft hole 212b of the bearing portion 212c and fixed to the game board 1, so that the rocking body 210 can swing around the shaft nail. Retained.
The instantaneous displacement means 220 is the same as the instantaneous displacement means 120 in the first embodiment in that it includes a piezoelectric element 221. However, in the case of the second embodiment, the piezoelectric element 221 formed in a flat plate shape is integrally fixed to the guide groove 212a, so that the piezoelectric element 221 directly contacts the return ball stopping bullet 211. It is configured as follows. In the second embodiment, the instantaneous displacement means 220 is the piezoelectric element 221 itself.

  The reverse detection unit 230 has the same configuration as the reverse detection unit 130 in the pachinko machine according to the first embodiment, and includes a switch body 231 and a detection tip 232.

  The stopper member 240 retreats in response to the game ball Q that is returned to the outlet 14 by the return ball stop bullet piece 211, and the return ball stop bullet piece 211 is moved to the outward step 3 a of the outer rail 3. In a state in which it is in contact with the detection tip 232 of the provided reverse detection means 230, the weight portion 212d of the base portion 212 of the swinging body 210 is in contact with the stopper member 240 and is arranged so as to prevent further swinging. Composed.

The effect | action by the structure of 2nd Embodiment is mainly demonstrated with reference to FIGS.
The launched game ball Q jumps out to the game area 2 while slightly deforming the return ball stopping bullet piece 211 formed of an elastic band plate from the outlet 14 through the guidance area 13.
FIG. 10 shows a state where the game ball is still on the way of returning, that is, a state where the ball return prevention device 200 is not receiving any action of the game ball Q. In this state, due to the action of the weight part 212d, the return ball stopping bullet member 211 is in a state in which the pop-out port 14 is substantially closed while being separated from the outward stepped part 3a of the outer rail 3. Further, in this state, a predetermined gap is secured between the base body portion 212 of the oscillator 210 and the stopper member 240.
When the game ball Q once jumped out to the game area 2 goes back to the pop-out port 14 again, the game ball Q hits the return ball stopping bullet 211 and rotates it in the backward direction (counterclockwise in the drawing). As shown in FIG. At this time, the tip of the return ball stopping bullet 211 hits the detection tip 232 of the reverse detection means 230, and the switch is turned on. Further, the weight portion 212 d of the base body portion 212 of the rocking body 210 is prevented from further rocking by the stopper member 240.
The detection signal of the detection unit 230 is transmitted to the control unit, and the control unit applies a voltage to the piezoelectric element 221 via the booster circuit.
The piezoelectric element 221 is instantaneously deformed (thickness increase) due to the reverse piezoelectric effect by applying a voltage, and the return ball stopping bullet 211 is instantaneously moved forward (clockwise in the drawing). As a result, the return ball stopping bullet 211 repels the game ball Q (FIG. 12). At this time, the stopper member 240 prevents the piezoelectric element 221 from moving forward (counterclockwise) on the base portion 212 of the oscillator 210. As a result, the game ball Q is effectively ejected by the return ball stopping bullet segment 211.
As a result, also in the ball return prevention device 200 of the second embodiment, the game ball Q that has gone back to the outlet 14 is bounced back to the A area or B area of FIG. Unlike the prior art, it does not easily flow down to the D region, but rather has a higher possibility of a trajectory flowing down to the C region, and the possibility of winning the start winning device 6 is also increased. Therefore, even if it is a return ball, it is possible to keep the player expecting a favorable winning.
When the application of voltage to the piezoelectric element 221 is stopped, the piezoelectric element 221 returns to its original state, and the return ball stopping bullet 211 returns to its original position (FIG. 10).

  In the second embodiment, the piezoelectric element 221 is provided in the guide groove 212a of the bearing portion 212C of the base portion 212 of the oscillator 210, but the surface of the weight portion 212d facing the stopper member 240, the weight portion 212d of the stopper member 240. You may provide in the surface which opposes. Due to the inverse piezoelectric effect of the piezoelectric element 221, the swinging body 210 is instantaneously displaced in the clockwise direction, so that the game ball Q can be ejected toward the center of the game area 2.

In the first and second embodiments described above, the instantaneous displacement means 120, 220 having the piezoelectric elements 121, 221 is used, but a solenoid or other means capable of instantaneous displacement is used instead of the piezoelectric element. Can do. Such a configuration is also within the scope of the present invention.
In the first and second embodiments, the pachinko gaming machine is used. However, the gaming machine according to the present invention is a pachinko gaming machine, and a launched game ball jumps out from the outlet through the guidance area to the game area. Is adapted to the gaming machine in which the game is configured by flowing down the game area.
