Description

The present invention relates to a pachinko gaming machine having a function of preventing an illegal act of guiding a game ball launched on a game board using a magnet to a specific winning opening.

Some pachinko machines can win big hits with a very high probability of winning by putting a game ball into a specific winning hole, or a big hit by putting a game ball into a specific winning hole There is a pachinko machine that is extremely heavy on a single ball that wins a specific winning slot, such as a model that can be used to win a game (a model called a so-called “one-shot stand”). In the case of such a pachinko gaming machine, it is easy to be targeted by a fraudulent act in which a game ball is won in an illegal manner at a specific winning opening to obtain a right of winning a big game. A typical technique is to lightly press a strong magnet against a glass plate fitted in the front door window (hereinafter, this glass plate is called a transparent plate) and attract the game ball fired on the game board to the magnet. There is a fraudulent act called magnet goto that leads to the specific winning opening. To prevent this, conventional pachinko machines are equipped with a magnetic sensor or the like behind the game board to detect the magnetism of the magnet, and when the magnet is brought close to the magnetic sensor, it is considered an illegal act and alarm Is adopted. However, fraud detection using the above magnetic sensor requires an additional sensor control circuit, resulting in an increase in equipment cost, and fraudulent activity between the time the hall employee arrives at the site after the fraudulent act has been performed by the magnet. There is a problem that the crime cannot be specified if the magnet is given to the friend and the evidence is destroyed. As described above, the detection by the magnetic sensor cannot eliminate the fraud itself, and does not lead to substantial damage on the store side.

For this reason, in Patent Document 1 below, a stopper formed of a magnetic material is disposed so as to be able to appear and retract in the vicinity of the entrance of the winning opening, and when the magnet is not approaching, the stopper is balanced by its own weight and does not act behind the game board. While waiting at the position, when the magnet approaches, the stopper is attracted by the magnet and protrudes to the upper part of the entrance of the winning opening, thereby preventing the game ball from entering the winning opening.
Japanese Utility Model Publication No. 5-70582

However, in the above-mentioned Patent Document 1, the stopper is held in its standby position by its own weight so that it does not protrude from the game board at normal times when the magnetic force of the magnet is not acting. However, in order to operate the stopper with a small magnetic force, the stopper It is necessary to make the mass of the extremely small. However, if the weight of the stopper is reduced, the balance at the standby position due to its own weight is easily broken by vibration of the machine being played, and the stopper may suddenly protrude to the entrance of the winning opening during the game due to some impact. In addition, if the stopper malfunctions, the game cannot be continued thereafter, so the hall employee must open the front door (glass frame) of the pachinko machine and return the stopper to the standby position by hand each time. There is a problem of increasing the work load of.

The present invention has been made paying attention to the problem that the conventional apparatus for preventing fraud by the magnet has, and is arranged along the inner surface of the transparent plate in the vicinity of the entrance of the winning opening arranged on the game board surface. In order to prevent illegal acts that use a magnet to guide the game ball to the winning opening, and allow the game ball that normally flows down the game board surface to enter the winning opening. An object of the present invention is to provide a pachinko gaming machine configured as described above.

  The invention according to claim 1 is attached to the main body frame holding the game board, the front door attached to the front surface of the main body frame so as to be able to open and close so as to cover the board surface of the game board, and the back surface of the front door. In the state where the front door is closed, it has a flat plate-like transparent plate facing a game space having a predetermined depth width between the game board and the surface of the game board. A large-sized accessory device is arranged, and the accessory device protrudes from the game board surface into the game space so that the front surface of the frame portion is close to the transparent plate, and a game below the accessory device. In a pachinko gaming machine having a winning opening provided with an entrance for receiving a game ball flowing down the game space with respect to the board surface, the lower side of the frame part of the accessory device extends along the inner surface of the transparent plate. A vertical wall extending vertically downward to a position near the height of the entrance of the prize opening An obstacle having a shape of an obstacle, the width of the vertical wall-like obstacle part of the obstacle being equal to or wider than the entrance width of the prize opening, and at least the contour part of the obstacle The level difference between the back surface of the transparent plate and the back surface of the transparent plate is sized so as to prevent the game ball from getting over in the thickness direction of the transparent plate, and the game space flows down between the back surface of the obstacle and the game board surface. The game ball to be opposed to the game board surface with a gap through which the game ball can pass toward the entrance of the winning opening, and the distance between the lower end of the obstacle portion of the vertical wall shape in the obstacle and the entrance of the winning opening, or The distance between the game board surface near the entrance of the winning opening and the substantial entrance made of a plurality of obstacle nails planted at a predetermined interval is smaller than the diameter of the game ball and is in contact with the back surface of the transparent plate. Size that can prevent the passing of a moving game ball Characterized in that it was.

  In other words, the present invention provides a special prize opening where a jackpot is fixed when a game ball enters, or a special prize start opening such as a special figure starting opening where a big prize lottery is executed with high probability. In a pachinko gaming machine that is arranged below a frame portion of an accessory device formed of a material such as a synthetic resin (plastic) that is one of magnetic materials, a part of the frame portion of the accessory device is attached to the prize opening. By extending downward toward the entrance, an obstacle is installed at the entrance of the winning opening. (See FIGS. 25 to 37)

That is, the obstacle according to the present invention attracts the game ball with a powerful magnet lightly pressed against the front surface of the transparent plate, and the winning hole is placed along the back surface (the surface facing the game board) of the transparent plate. This is for preventing the game ball from being guided to the entrance. Therefore, one of the conditions as the obstacle is a form that sucks the game ball with a magnet and prevents it from being illegally guided to the entrance of the winning opening along the back of the transparent plate. Is a form that does not prevent the game ball that normally flows down the game space from passing toward the entrance of the winning opening, and it is necessary to satisfy at least these conditions. That is, the obstacle needs to have a predetermined size that the step between the back surface of the transparent plate and the back surface of the transparent plate is difficult for the game ball to get over in the thickness direction of the transparent plate, and the obstacle and the entrance. The distance between the back surface of the obstacle and the surface of the game board is larger than the diameter of the game ball. is necessary.

The vertical wall-like obstacle portion of the obstacle has a width equal to or larger than the entrance width of the prize opening. This is to prevent the player from entering the entrance of the winning opening. As used herein, “entrance to the prize opening” means that a winning ball is paid out by entering a game ball, or a state that is advantageous to the player (for example, a state where a jackpot right is acquired). It is not a term that refers only to the mouth, but is a broad concept including, for example, the entrance of a guide passage for a game ball that leads to a winning opening that is advantageous to the player. Further, the entrance width of the winning opening means that when a plurality of obstacle nails are installed above the winning opening, as shown in FIGS. 24 and 28, the shaft 58L of one obstacle nail 341L is connected to the other. The clearance dimension L6 to the shaft part 58R of the obstacle nail 341R is indicated. Of course, in a situation where the head of the obstacle nail greatly affects the probability of entering the winning entrance, the separation distance of the head may be interpreted as the entrance width of the winning entrance.

The size of the step between the back surface of the obstacle and the back surface of the transparent plate that can prevent the game ball from getting over in the thickness direction of the transparent plate is, for example, a magnet pressed against the front surface of the transparent plate Assuming that the attraction force is infinite, if the size of the step is equal to or larger than the radius of the game ball, the game ball can be completely prevented from getting over the step. In reality, however, there is a limit to the attractive force of a magnet that can be carried by a fraudster, so even if the step size is less than or equal to the radius of the game ball, the attractive force of the magnet can be predicted in advance. If the value is assumed, it is possible to obtain in advance the size of the step where the game ball cannot be overcome. As one of the conditions for the game ball to overcome the step, the distance between the point where the game ball contacts the obstacle and the back of the transparent plate is a substantial step, so that the shape of the side of the obstacle is as much as possible. It is important to design the point in contact with the sphere as far as possible from the back of the transparent plate.

The distance between the obstacle and the entrance of the prize opening, or the distance between the obstacle and the entrance substantially consisting of a plurality of obstacle nails planted at a predetermined interval with respect to the game board surface near the entrance of the prize opening. The reason why the distance is smaller than the diameter of the game ball and is capable of preventing the game ball rolling while contacting the back surface of the transparent plate is that the game ball attracted to the back surface of the transparent plate by a magnet Is defined so as not to enter through the gap between the lower end of the obstacle and the entrance of the winning opening. That is, as described for the size of the step between the back surface of the obstacle and the transparent plate, the conditions for the size of the gap also differ depending on the magnet's attracting force to be used. Assuming the range, it is only necessary to set a substantial gap between the lower end of the minimum obstacle necessary to prevent the game ball from passing and the entrance of the winning opening. As shown in FIGS. 24 and 28, the distance L1 between the lower end of the obstacle and the obstacle nail that substantially defines the entrance of the prize opening is generally below the obstacle nail from the shaft portion of the obstacle nail. Although it is the distance to the end face, when the head of the obstacle nail is closest to the obstacle, it means the distance between the head of the obstacle nail and the lower end face of the obstacle.

Is arranged. A number of obstacle nails (not shown) are planted in the game board 5, and the game balls released upward from the upper left side of the game board 5 along the outer guide rail 3 a are connected to the board surface of the game board 5. The game space S formed between itself and the transparent plate 55 falls downward while colliding with the obstacle nail.

At the upper center of the game board 5, a first accessory device 14 having a first game ball sorting stage (described later) formed therein is installed. Of the game balls that have entered the first accessory device 14, only the game balls that have passed through a predetermined passage by the first sorting stage are released from the game board 5 into the game space S again.

Windmills 15 and 16 that change in the flow direction of the game ball are rotatably installed on the diagonally upper left and right sides of the first accessory device 14. Further, an ordinary winning opening 17 is provided on the left side of the first accessory device 14 through which a predetermined winning ball is paid out when a winning game ball is won.

  On the other hand, a windmill 18 for changing the flow direction of the game ball discharged from the inside of the accessory device 14 to the game space S on the front surface of the game board 5 is installed below the first accessory device 14. An obstruction nail (not shown) is disposed around the windmill 18 so as to surround it. (Details will be described with reference to FIG. 10.)

Also, below the windmill 18, a second accessory device 19 having a circular second game ball sorting stage called “Kroon” inside is disposed. Note that only the game balls that have passed through the first accessory device 14 and the passage surrounded by the windmill 18 and the obstacle nail are configured to have a high possibility of entering the second accessory device 19.

Also, only the game balls that have entered the special winning opening (specific hole) and passed through the specific path in the second game ball distribution stage in the second accessory device 19 are located below the second accessory device. The first start winning opening 20 installed in the can be entered.

That is, when a game ball enters the first start winning opening 20, a predetermined number of prize balls are paid out from a prize ball device (not shown) to the ball receiver 6, and a big hit lottery means provided on the control board is provided. The jackpot lottery is executed, and it is determined whether or not the player can execute the jackpot game. The lottery result of the jackpot lottery is notified to the player by displaying the symbols on the special symbol display unit 21 for a predetermined time and then displaying the symbols in a stopped manner.

When the jackpot lottery is won, a jackpot game is started in which a jackpot 22 for the special electric accessory 23 is opened, and a special prize opening (large (Winning opening) 22 is opened. The special winning opening (large winning opening) 22 is formed in a horizontally-long rectangular shape, and has a size that allows a plurality of game balls to enter simultaneously. In connection with the special winning opening 22, the special winning opening 22 An opening / closing plate 23 (special electric accessory) is provided that opens and closes between an open state for guiding the game ball to a closed state and a closed state for preventing the game ball from entering the special winning opening (large winning opening) 22. Yes. The open / close plate 23 closes the special prize opening 22 in a flush state along the board surface of the game board 5, and prevents the game ball from entering the special prize opening 22. From the state, the special prize opening 22 is opened by falling on the front side around a pivot shaft (not shown) arranged along the lower edge of the special prize opening 22 and falls onto the special prize opening 22. The incoming game ball can be received on the inner surface and introduced into the special winning opening 22.

When the jackpot game ends, the game shifts to a so-called probability change game state. In the short-time game executed in this probable gaming state, the second start winning port 24 opened below the large winning port 22 is opened. The lottery for determining whether or not to open the second start winning opening is executed every time the game ball passes through the through gate 26, and the lottery result is obtained by selecting a predetermined light emitting diode on the normal symbol display unit 27. After blinking for a time and displaying the fluctuation, the light-emitting diode is lit continuously to confirm the display.

A special symbol display unit 21, a normal symbol display unit 27, a special symbol hold display unit 28, and a normal symbol hold display unit 29 are provided on the left side of the second accessory device 19. The special symbol display unit 21 uses a 7-segment display, and performs a segment display indicating a special symbol lottery result for each start winning prize. The normal symbol display unit 27 uses, for example, red and green light emitting diodes. When the game ball passes through the normal symbol start gate 26, a lottery is performed. When the lottery is won, The red light emitting diode is turned on, and the ordinary electric accessory (opening / closing plate) 25 is opened for a predetermined time and number of times. On the other hand, the green light-emitting diode lights up when it is off. The special symbol hold display unit 28 and the normal symbol hold display unit 29 use light emitting diodes, and display the number of game balls on which the result display regarding the lottery of the special symbol and the normal symbol is held.

Next, the structure of the first accessory device 14 will be described with reference to FIGS. 3 is a perspective view of the first accessory device 14 as viewed from above, FIG. 4 is a front view of the first accessory device 14, and FIG. 5 is a frame portion 900 from the first accessory device 14 in the state of FIG. And it is a front view which shows the state which removed the board | substrate 82 for attaching the said 1st accessory apparatus 14 to the game board 5. FIG.

In FIG. 3, the first accessory device 14 has a main body case 80 having a box shape with an opening on the front surface and the first game ball sorting stage 200 on the inner bottom surface, A frame portion 900 attached to the front surface of the case 80, a mounting board 82 for fixing the main body case 80 and the frame portion 900 to the front surface of the game board 5, and a jellyfish-type accessory 83 attached to the front surface of the mounting board 82. And attachment side portions 85L and 85R attached to the left and right side surface portions 84L and 84R of the main body case 80, respectively. The jellyfish accessory 83 incorporates a lamp L2 (not shown) and is used for production.

The main body case 80 includes a main body case upper surface portion 81, main body case side surface portions (left and right two side surfaces) 84L and 84R, a main body case rear surface portion 86, and a first game ball sorting stage 200 on the main body case bottom surface portion. It is composed of The main body case 80, the attachment side portions (84L, 84R), the attachment substrate 82, and the frame portion 900 are made of a plastic material having excellent transparency such as polycarbonate or acrylic resin. Note that the jellyfish accessory 83 is made of ceramic.

Next, the approach path of the game balls to the first game ball sorting stage will be described with reference to FIGS. First, when a game ball flowing down the game space S on the front surface of the game board 5 enters the side introduction openings 87L and 87R of the frame portion 900, a so-called warp passage 88L of the main body case attachment side portions 85L and 85R. , 88R is introduced into the space in the frame portion 900 connected to 88R. Thereafter, the game ball changes the direction of movement by about 90 °, passes through the warp passages 88L and 88R formed in the attachment side portions 85L and 85R from the main body case side portion introduction openings 99L and 99R, and again. The direction is changed by about 90 °, and finally the first game ball sorting stage 200 is reached. A dotted line A in FIG. 19 shows a trajectory where the game ball passes from the side introduction opening 87L of the frame portion 900 through the warp passage 88L to the first game ball sorting stage 200. Note that only the game balls introduced into the first accessory device 14 have a possibility of entering the first start winning opening 20, and other game balls may enter the first start winning opening. It has a gauge configuration that does not enter 20.

As shown in FIGS. 6 to 9, the sorting stage 200 of the first accessory device 14 includes a rear stage 201 that receives the game balls introduced through the warp passages 88L and 88R as described above, and The front stage 202 is arranged on the front side of the rear stage 201. On the upper surface of the rear stage 201, a pair of left and right inclined paths 203L and 203R for guiding the game ball to the front stage 202 side are provided. In addition, on the upper surface of the front stage 202, a pair of left and right circular orbiting motion recesses 204L and 204R having a mortar-shaped bottom surface shape in which the entered game ball gradually moves toward the center while performing a circumferential rotation motion. Corresponding to the advantageous side guide path 205 linearly formed in the front-rear direction between the pair of circular motion recesses 204L and 204R, and the inclination of the rear stage 201 corresponding to the pair of circular motion recesses 204L and 204R. A pair of left and right recess guide paths 206L and 206R are provided for guiding the game balls from the paths 203L, 263L, 273L, 203R, 263R, and 273R to the respective circumferential rotation motion recesses 204L and 204R, respectively.

A single detachment ball drop hole 207L, 207R is provided at the center of each of the circular motion recesses 204L, 204R, and the game ball dropped into the detachment ball drop holes 207L, 207R is attached to the mounting side from the front stage 202. Games on the front surface of the game board 5 from the game ball discharge ports 89L and 89R (see FIG. 5) of the attachment side portions 85L and 85R via the game ball passages 209L and 209R extending to the side portions 85L and 85R, respectively. It is returned to the space S. The trajectory of the game ball from the off-ball drop hole 207L to the game ball discharge port is indicated by a dotted line B in FIG. Further, the advantageous side guide path 205 is formed with an inclined surface whose bottom portion is gently inclined from the front side toward the rear side, and the game balls that have entered the advantageous side guide path 205 From the rear end opening 210, through the guide path 212 provided in the front stage 202, the game ball is released into the game space S on the front surface of the game board 5 in the direction in which the windmill 18 is installed.

In addition, the movement state of the game ball that has passed through the guide path 212 and is released from the discharge port 211 to the game space S can be clearly seen from the first hole 351 of the frame 900. In addition, the protrusion 361 at the bottom of the frame 900 having the first hole 351 has a large momentum from the discharge port 211 as well as the effect of using the magnet to guide the game ball and preventing the cheating to win the winning port. It plays a role in preventing the game ball released in the state from directly colliding with the front transparent plate. When the movement of the game ball in the first accessory device 14 is confirmed with the front door 3 opened, the game ball passes through the guide path 212 and jumps out of the machine from the discharge port 211. There is also a role to prevent this. Note that the game balls released from the game ball discharge ports 89L and 89R to the game board 5 are introduced into the second accessory device 19 due to a gauge configuration (arrangement of accessory, obstacle nail, etc.). There is also no entry into the first start winning opening 20.

Further, each of the concave guide paths 206L and 206R approaches the outer peripheral edge from the rear of one of the left and right circular motion concave parts 204L and 204R, and passes from the outer peripheral edge to the front peripheral edge to the other circumferential rotational movement concave part 204R. , 204L is extended to the front peripheral edge portion, and the game ball is guided to both the circular motion recesses 204L, 204R. In addition, each recess guide path 206L, 206R intersects the outer periphery of the circular motion recesses 204L, 204R in the substantially tangential direction at a position approaching the outer peripheral edge from the rear of one of the circular motion recesses 204L, 204R. The circumferential rotation recesses 204R and 204L are provided so as to intersect the outer circumferences of the circumferential rotation recesses 204R and 204L in a substantially tangential direction at locations extending to the front peripheral edges. When the game balls guided by the recess guide paths 206L and 206R enter one of the circular motion recesses 204L and 204R, the other game balls rotate in a circular motion in the circular motion recesses 204L and 204R. The game balls that enter the game ball colliding with each other can be bounced off, and the orbital movement recesses 204L and 204R are located on the side of the advantageous guide path 205 even if the game balls enter vigorously. It has a depth that is difficult to jump out, and is configured such that only game balls that have been jumped off by collision between game balls can enter the advantageous guide path 205. FIG. 20A shows a trajectory of the game ball that has been bounced off by the collision between the game balls enters the advantageous side guide path 205 and falls to the rear end opening 210. In addition, two game balls collide with each other at the rear stage 201. As a result, one ball that has been flipped moves from the concave guide path 206L to the front stage 202, and the other ball that has been blown off By moving from the concave guide path 206R to the front stage 202, two game balls may collide again on the front stage, and one of them may enter the advantageous side guide path 205. The trajectory of the game ball at this time is shown in FIG.

In the center of the rear stage 201, a bowl-shaped protrusion 213 is provided to reduce the momentum of the game ball rolling left and right on the rear stage. Further, a shallow inclined groove 214 is provided at the front end of the ridge line of the hook-shaped protrusion 213 toward the rear end opening 210 of the advantageous side guide path 205, and the game ball is extremely rarely formed by the shallow inclined groove 214. It may fall directly onto the guide path 212 through the rear end opening 210 of the advantageous side guide path 205.

Next, in the first game ball sorting stage 200 of the first accessory device, the ball dropped from the rear end opening 210 of the advantageous side guide path 205 to the guide path 212 and was discharged from the discharge port 211 to the game board 5. The behavior of the game ball will be described with reference to FIG.

The game ball returned to the game board 5 from the discharge port 211 is changed in the flow direction by the windmill 18 and a plurality of obstacle nails arranged in the region 250. Specifically, the game ball released from the discharge port 211 to the game board 5 falls on the game board in a substantially vertical direction. First, it passes between the right and left obstacle nails aL and aR (more precisely, between the aL axis and the aR axis). The distance between aL and aR is, for example, 13 mm, and a game ball having a diameter of 11 mm passes between aL and aR and reaches the windmill 18 unless the discharge ball 211 is so irregularly discharged.

The game ball that has reached the windmill 18 is influenced by the approach direction to the windmill, the stop positions of the game ball holding portions 50, 50, 50 provided on the windmill, etc. The The rolling direction of the game ball is determined mainly by the obstacle nails bL and bR and cL and cR. For example, a game ball whose rolling direction is changed to the right rotation direction by the windmill 18 changes the rolling direction inward (in the direction of the nail cR) by collision with the obstacle nail bR, and between the obstacle nail cL-cR. And passes between dL and dR and enters the introduction portion 301 of the frame portion 92 of the second accessory device 19 described later.

On the other hand, the game ball whose rolling direction is changed to the left rotation direction by the windmill 18 changes the rolling direction inward (in the direction of the nail cL) due to the collision with the obstacle nail bL, and the obstacle nail cL-cR. And between dL and dR and enters the introduction portion 301 of the frame portion 92 of the second accessory device 19 described later.

The ratio (hereinafter referred to as introduction rate) of the game balls released from the release port 211 to the introduction part 301 of the frame part 92 of the second accessory device 19 is adjusted. It is only necessary to adjust four nails. That is, in order to increase the introduction rate, it is only necessary to widen between bR and cR and between bL and cL and widen between cL and cR. On the contrary, in order to reduce the introduction rate, it is only necessary to narrow between bR and cR and between bL and cL and narrow between cL and cR. As described above, by adjusting the nail, it is possible to adjust the rate at which the game ball released from the discharge port 210 to the game board 5 enters the introduction portion 301 of the frame portion 92 in the second accessory device 19. Accordingly, as described above, when a change in the winning rate of the first start winning opening 20 occurs due to a change in the tilt angle of the sorting device due to the impact of the gaming board 5 or the like that occurs when opening and closing the main body frame 56 of the pachinko gaming machine For example, it is possible to finally set the winning rate to the first start winning port 20 to an appropriate value by adjusting the ball entering rate to the introduction port 301 by adjusting the obstacle nail. . FIG. 21 shows a trajectory when the game ball released from the discharge port 211 enters the game board 5 enters the introduction part 301 of the frame part 92 of the second accessory device 19.

Here, the rolling direction of the game ball released from the discharge port 211 to the game board 5 is first changed by the windmill 18. If the purpose is to adjust the introduction rate when the game ball released from the discharge port 211 enters the introduction part 301 of the frame part 92 in the second accessory device 19, dare It is possible to adjust the rate of introduction of the game ball into the introduction part 301 of the frame part 92 in the second accessory device 19 by arranging only the nail in the obstacle nail arrangement region 250 without arranging the windmill. However, if the distribution is made only with the obstacle nail, the player can easily guess the level of the entry rate, so that the game is likely to be monotonous from the viewpoint of game play and the introduction rate is expected to be low. There is a problem that the availability of the machine decreases.

In that regard, when a freely rotating windmill is provided, for example, as shown in FIG. 10, when the game ball holding unit 50 happens to be in the “Y-shaped” angular position relationship, the game ball is entangled with the windmill. Then, the rotational force of the windmill works to the maximum, and the game ball entangled with the windmill may reach the introduction part 301 directly without contacting the surrounding obstacle nails (particularly bL and bR in FIG. 10). In other words, it is possible to realize various games such that the movement trajectory of the game ball flowing down in association with the windmill changes depending on the standby angle of the windmill.

Next, the second accessory device 19 will be described with reference to FIGS. 11 and 12. The second accessory device includes a main body case 90, a substrate 91, and a frame portion 92. The main body case 90 includes an upper surface portion 95, side surface portions 93L and 93R (not shown), a back surface portion 94, and a second sorting stage 400 that forms the bottom surface portion. The second accessory device 19 is attached to the game board 5 by a substrate 91. The main body case 90, the substrate 91, and the frame portion 92 are molded from a synthetic resin excellent in impact resistance and wear resistance, such as polycarbonate resin.

Next, the mechanism by which the game ball is introduced into the second accessory device 19 will be described. A game ball that is discharged from the discharge port 211 of the first accessory device 14, passes through the windmill 18 and the obstacle nail placement region 250, and reaches the introduction portion 301 of the frame portion 92 is transferred from the introduction portion 301. Then, it passes through the warp passage 302 in the frame portion 92 and the warp passage 303 in the side surface portion 93L of the main body case, and reaches the second sorting stage 400. In FIG. 22, the trajectory of the game ball passing through the warp passage 302 in the front decorative frame 92 and the warp passage 303 in the main body case side surface 93 is indicated by a dotted line.

Next, the configuration of the second sorting stage 400 will be described with reference to FIG. The sorting stage 400 has an introduction portion 401 through which the game ball reaches the warp passage 303 and a bottom portion where the game ball that has entered from the introduction portion 401 gradually moves toward the center while making a circular motion. It is formed of a crushed portion 402 formed on a mortar-shaped slope and having three game ball dropping holes 403, 404, and 405 formed at the center. The said croon part 402 uses the concave surface which cut off a part of spherical concave surface with a radius of 200 mm as a component. If the radius is increased to about 200 mm, the game ball that is rotating in the circumferential direction in the clune part 402 maintains a certain speed until immediately before dropping into the drop holes 403, 404, and 405 in the center part. Since the circular motion continues, there is an effect that it is difficult to cause a so-called pachinko machine to vibrate and to fall illegally into a drop hole that is advantageous to the player (here, the drop hole 403 corresponds).

Next, with reference to FIGS. 14 and 15, the behavior after the game ball has dropped into the drop holes 403, 404, and 405 of the croon portion will be described. First, the game ball that has fallen into the advantageous drop hole 403 passes through the game ball guiding path 408, moves in the direction of the game board surface, and is discharged into the game space S from the discharge port 406. The released game ball enters the first start winning opening 20 with a high probability of almost 100%. The behavior of the game ball that passes through the game ball guiding path 408 and moves in the game board surface direction and is released onto the game board from the discharge port 406 is visible from the second hole 352 of the frame 92. . In addition, the protruding portion 362 below the frame portion 92 having the second hole portion 352 prevents an unauthorized person, which will be described in detail later, from guiding a game ball using a magnet and illegally winning a winning opening. In addition to the effect of enabling, there is also an effect of preventing the game ball released from the discharge port 406 with a large momentum from colliding with the front transparent plate. In addition, when a hall employee opens the front door 3 and checks the movement of the game ball in the second accessory device 19, the game ball released from the discharge port 406 is prevented from jumping out of the machine. There is also an effect.

Next, the game ball that has fallen into the drop hole 404 or 405 passes through the game ball guiding path 409, moves in the direction of the game board surface, and is discharged from the discharge port 407 onto the game board. The released game ball does not enter the start winning opening 20 and is discharged from the out ball opening 51 to the outside of the machine.

As described above, the goal of the game is to win a first start winning opening directly connected to the jackpot. For this reason, the illegal act of winning the first starting port by attracting the game ball using a magnet and guiding it to the upper part of the first winning port becomes a big problem. This prevention means is the gist of the present invention. Next, the details will be described with reference to FIGS.

FIG. 23 shows a front view (a) and a BB sectional view (b) of the second accessory device 19. In the figure, reference numeral 55 denotes a transparent plate such as a glass plate attached to the back surface of the front door 3. Usually, in order to enhance the anti-fraud effect, it has a double structure (a structure in which two glass plates are arranged in parallel at a predetermined interval), but here, in order to simplify the explanation, the side closer to the game board Only the transparent plate is shown. FIG. 24 is an enlarged view of region E in FIG. FIG. 25 is an enlarged view of the F region in FIG.

First, with reference to FIG. 25, the relationship between the protruding portion 362 of the lower portion of the frame portion 92 having the second hole portion 352 of the second accessory device 19, the transparent plate 55, and the game board 5 will be described. About the distance (FIG. 25, L3) to the back surface of a transparent plate, and the said protrusion part 362 surface, the relationship that the said protrusion part 362 is located in proximity to a transparent plate is required. Specifically, at least L3 needs to be smaller than the diameter D of the game ball. Of course, the game ball that has passed through the game ball guiding path 408 and is released from the discharge port 406 onto the game board needs to drop in the space to the first start winning opening, so FIG. L4 needs to be larger than the diameter D of the game ball.

Furthermore, the size of the step K between the back surface of the projecting portion 362 and the back surface of the transparent plate 55 must be such that the game ball cannot exceed the step K even if the game ball is guided using a magnet. is there. Preferably, if the step K is made larger than the radius of the game ball, the game ball cannot theoretically exceed the step even if the magnet attracting force is extremely large. However, since the attracting force of the permanent magnet that can be carried by the fraudster is limited, the size of the step K may be less than the radius of the game ball, and the value is experimentally assumed if the attracting force of the magnet is assumed. Can also be obtained easily. As another condition for determining whether or not the game ball cannot exceed the step K, the distance between the contact point of the game ball and the protruding portion 362 and the back surface of the transparent plate 55 becomes a problem. For example, if the end surface of the protruding portion 362 is inclined and the contact point with the game ball approaches the transparent plate 55, the effective height of the step K is reduced accordingly, so that the contact point with the game ball is as transparent as possible. The shape of the end surface of the protrusion 362 should be designed so as to be away from the back surface of the plate 55.

Next, FIG. 24 will be described. The distance L1 to the shafts 58L and 58R of the two obstacle nails 341L and 341R that substantially define the entrance width to the protrusion 362 and the first start winning opening 20 is smaller than the diameter D of the game ball. is there. When there is no two obstacle nails that substantially define the entrance to the first start winning opening 20 with the protrusion 362, the L1 is the upper opening 343 of the protrusion 362 and the first winning opening 20. And the distance. In addition, the relationship between the width L2 of the protruding portion 362 and the distance L6 between the obstacle nails 341L and 341R that substantially defines the entrance to the first start winning opening needs to be larger than L6. . In this case, L6 is changed to L7 when there is substantially no obstacle nail that defines the entrance to the first start winning opening. Here, the width of the protruding portion 362 is, for example, a portion that is roughly horizontal in the left-right direction of the distal end portion. Of course, the distance from the tip of the head of the obstacle nail 341L, 341R to the transparent plate 55 is smaller than the diameter D of the game ball.

However, in the above description, the description is made without taking into consideration the three-dimensional positional relationship of the game balls, and if this is taken into consideration, the game balls will not get over the head of the obstacle nail and run behind the protruding portion 362. As described above, the distance L1 between the protrusion 362 and the obstacle nails 341L and 341R should be set to be smaller. The distance can be easily determined by the same method as that for determining the size of the step K of the protrusion 362.

When the relationship between the transparent plate 55 and the protruding portion 362 and the relationship between the protruding portion 362 and the obstacle nail 341L, 341R are as shown above, the game ball is attracted through the transparent plate 55 with the magnet, It becomes impossible to move the game ball above the first start winning opening by changing the position to the magnet. That is, as shown in FIG. 26, even if the game ball is guided along the back surface of the transparent plate with a magnet so as to guide the game ball above the first start winning opening, the protrusion 362 and the obstacle nails 341L, 341R When the game ball is in contact with the side surface of the projecting portion 362, it is impossible for the game ball to exceed the step K of the projecting portion 362 even when the magnet attracting force is increased. Therefore, it is possible to prevent the game ball from being guided above the first winning opening. That is, if the game ball is forced to be guided above the winning opening 20 with a magnet, the gap between the game ball and the magnet is widened, and the magnetic force acting on the game ball is rapidly reduced, as shown in FIG. The game ball falls without entering the winning opening 20.

Next, as a second embodiment, a case will be described in which a start winning opening having a high probability of winning a jackpot or a special winning opening which is a jackpot when winning is installed below the first accessory device. FIG. 27 shows a case where a special winning opening 220 (specially called a V winning opening is selected because a big win is won when winning here) is installed under the same accessory apparatus as the first accessory apparatus 14. . In order for the game ball to win a special prize, as described in detail above, the game ball passes through the accessory device 14, and finally from the discharge port 211 (see FIGS. 5 and 6), the game board 5 It is a gage configuration with no possibility other than being released into

FIG. 28 is an enlarged view of region G in FIG. 27, and FIG. 29 is a cross-sectional view of the first accessory device 14 and the special prize opening in AA in FIG. FIG. 30 is an enlarged view of a region H in FIG. The second embodiment is also basically the same as the first embodiment for preventing illegal winning of a game ball to the winning opening 220 using a magnet, and the same reference numerals as those in FIGS. The parts shown are the same members and the same parts.

First, the relationship between the protrusion 361 at the bottom of the frame 900 having the first hole 351 of the first accessory device 14, the transparent plate 55, and the game board 5 will be described with reference to FIGS. 27, 29, and 30. . The distance between the back surface of the transparent plate 55 and the surface of the protruding portion 361 (FIG. 30, L3) requires a positional relationship in which the protruding portion 361 is biased toward the transparent plate 55. Specifically, at least L3 needs to be smaller than the diameter D of the game ball. Also, as a matter of course, since the game ball that has passed through the game ball guide path 212 and is released from the discharge port 211 onto the game board needs to pass through the game space S following the first start winning port, L4 in FIG. 30 needs to be larger than the diameter D of the game ball.

Next, referring to FIG. 28, the distance L1 to the shaft portions 59L and 59R of the two obstacle nails 342L and 342R that substantially define the entrance to the protruding portion 361 and the special prize opening 220 is a game ball. Is smaller than the diameter D. In addition, the relationship between the width L2 of the protruding portion 361 and the inter-axis distance L6 between the obstacle nails 342L and 342R that substantially defines the entrance to the first start winning opening needs to be larger than L6. There is. Here, the width of the protruding portion 361 is, for example, a portion that is roughly horizontal in the left-right direction of the distal end portion. As a matter of course, the distance from the tip of the head of the obstacle nail 342L, 342R to the transparent plate 55 is smaller than the diameter D of the game ball.

Furthermore, the size of the step K between the back surface of the projecting portion 361 and the back surface of the transparent plate 55 must be such that the game ball cannot exceed the step K even if the game ball is guided using a magnet. is there. Preferably, if the step K is made larger than the radius of the game ball, the game ball cannot theoretically exceed the step even if the magnet attracting force is extremely large. However, since the attracting force of the permanent magnet that can be carried by the fraudster is limited, the size of the step K may be less than the radius of the game ball, and the value is experimentally assumed if the attracting force of the magnet is assumed. Can also be obtained easily. As another condition for determining whether or not the game ball cannot exceed the step K, the distance between the contact point between the game ball and the protruding portion 361 and the back surface of the transparent plate 55 becomes a problem. For example, if the end surface of the protruding portion 361 is inclined and the contact point with the game ball approaches the transparent plate 55, the effective height of the step K is reduced accordingly, so that the contact point with the game ball is as transparent as possible. The shape of the end surface of the protrusion 361 should be designed so as to be away from the back surface of the plate 55.

When the transparent plate 55, the projecting portion 361 and the obstacle nails 342L and 342R maintain the relationship as described above, the game ball is attracted through the transparent plate with a magnet, and the game ball is moved to the special prize opening by moving the magnet. It is impossible to move the game ball above 220. That is, as shown in FIG. 31, when the game ball is moved along the back surface of the transparent plate with a magnet, the protrusion 361 and the obstacle nail 342L, even if trying to guide the game ball above the special prize opening 220, Since the 342R gets caught and gets in the way, and the game ball is in contact with the side surface of the protrusion 361, the game ball cannot get over the step K between the protrusion 361 and the transparent plate 55. It is impossible to guide the game ball up 220. In other words, if the game ball is forced to be guided above the special prize opening 220 with a magnet, the distance between the game ball and the magnet is increased, and the magnetic force acting on the game ball is rapidly reduced, as shown in FIG. The game ball falls without entering the winning opening 220.

In the second embodiment, a game ball that rolls on the game ball sorting stage 200 (see FIGS. 6 to 9) in the first accessory device 14 as an illegal act using a magnet that may occur. On the other hand, there is one that uses a magnet to change the movement of the game ball so as to be advantageous (the game ball enters the discharge port 210). As described above, when a game ball enters the discharge port 210, almost 100% of the game ball enters the special winning port 220, which may be a target point for the fraudster. With respect to an illegal act using a magnet for the game ball of the game ball distribution stage, it is possible to detect the illegal act by installing a magnet sensor 38 (see FIGS. 5 and 9).

On the other hand, as described above, when the game balls guided by the respective recess guide paths 206L and 206R enter one of the circular motion recesses 204L and 204R, the distribution stage 200 has another circular motion recess. 204L and 204R are designed so that both game balls collide with each other and can enter the game ball that can enter, and the orbital movement recesses 204L and 204R enter the game balls vigorously. However, it has a depth that makes it difficult to jump out to the side of the advantageous side guide path 205 and is configured such that only the game balls that are jumped off by the collision of the game balls can enter the side of the advantageous side guide path 205 (FIG. 20). That is, when a plurality of game balls collide accidentally, one of them enters the discharge port 210. Accordingly, even if an attempt is made to cheat using the magnet in the distribution stage 200, a plurality of game balls must be controlled, making it difficult to illegally guide the game balls to the discharge port 210. . Therefore, it can be said that the structure of the distribution stage 200 itself is a structure that is strong against fraud using a magnet.

Next, a third embodiment of the present invention is shown in FIGS. Unlike the first and second embodiments, the winning device 700 of this embodiment is such that a portion of the winning device 700 including a winning opening has a fraud prevention function using the magnet. FIG. 32A is a front view of the winning device 700, and FIG. 32B is a plan view of the winning device 700 as viewed from above. FIG. 32C is an AA cross-sectional view of the winning device 700 shown in FIG. However, illustration of nails 708L and 708R is omitted in FIG. FIG. 33 (d) is a perspective view of the winning device 700 viewed from an oblique front, and FIG. 33 (e) is a perspective view from the oblique rear.

As shown in FIGS. 32 to 34, a prize winning device 700 having a function of preventing illegal acts by a magnet according to the present embodiment is installed around a prize winning cylinder section 704 having a prize winning opening 701 and the winning prize cylinder section. Obstacle 706 having a function of preventing fraud using a magnet composed of a surrounding obstacle part 702 and a roof-like upper obstacle part 703 that is connected to the surrounding obstacle part 702 and covers the top of the winning port 701 And a substrate 705 for attaching the winning cylinder 704 to the game board.

Normally, when entering the winning hole 701, the obstacle nail 708L which flows down on the nail arrangement 710L or 710R in FIG. 33 (d) toward the winning hole and substantially defines the width of the winning hole. , 708R to enter the winning opening 701. At this time, the distance L8 between the upper obstacle portion 703 and the game board 5 is at least larger than the diameter D of the game ball so that the game ball can enter from above the winning opening 701.

At this time, the size of the step K1 between the back surface of the surrounding obstacle 702 and the back surface of the transparent plate 55 needs to be set so that the game ball cannot exceed the step K1 even if the game ball is guided using a magnet. It is. Preferably, if the level of the step K1 is larger than the radius of the game ball, the game ball cannot theoretically exceed the step even if the magnet's attractive force is extremely large. However, since the attracting force of the permanent magnet that can be carried by the fraudster is limited, the size of the step K1 may be equal to or less than the radius of the game ball, and the value is experimentally assuming the attracting force of the magnet. Can also be obtained easily. In addition, as another condition for determining whether or not the game ball cannot exceed the step K1, the distance between the contact point of the game ball with respect to the side surface of the peripheral obstacle 702 and the back surface of the transparent plate 55 is a substantial step. . For example, if the end face of the surrounding obstacle portion 702 is inclined and the contact point with the game ball approaches the transparent plate 55, the effective height of the step K1 is reduced accordingly, so that the contact point with the game ball is as much as possible. The shape of the end surface of the peripheral obstacle portion 702 should be designed so as to be away from the back surface of the transparent plate 55.

Further, the size of the step K2 between the back surface of the upper obstacle portion 703 and the back surface of the transparent plate 55 is determined by attracting a game ball using a magnet and guiding the magnet above the upper obstacle portion 703. Even if the game ball is to be dropped and dropped into the winning hole 701, it is necessary that the game ball does not fall to the back side of the upper obstacle 703. Preferably, the step K2 is made larger than the radius of the game ball, and a rib 713 is provided on the upper surface of the upper obstacle 703 to prevent the game ball from falling to the back side, or a transparent plate 55 It is more effective to form an inclined surface that inclines downward toward the side.

According to the above configuration, even if an illegal act of attracting the game ball by the magnet pressed against the front surface of the transparent plate 55 and guiding it to the winning port 701 along the back surface of the transparent plate 55 is performed, The illegal obstacle from the direction is prevented by the upper obstacle portion 703. An example is shown in FIG. That is, since the steps K1 and K2 between the back surface of the obstacle 706 and the back surface of the transparent plate 55 are both larger than the radius of the game ball, when the game ball is guided by the magnet from above the winning opening 701, The game ball that has come into contact with the upper obstacle portion 703 cannot move around to the back side of the upper obstacle portion 703 beyond the step K2, but moves sideways along the roof-like upper obstacle portion 703, and the nail arrangement 710R. In this case, it falls downward from between the nail closest to the winning port 701 and the winning port cylinder portion 704. Note that the width L11 of the upper obstacle portion is the axis of the nail 708L, 708R that substantially defines the width of the winning opening 701 so that the game ball that has moved through the upper obstacle 703 does not enter the winning opening 701. It is larger than the distance L10.

In addition, when an illegal act is performed in which a game ball is attracted from the magnet boil and guided to the winning port 701 along the back surface of the transparent plate 55, the game ball guided from the side surface direction of the winning port 701 has a surrounding obstacle portion 702. The ball entering the winning opening 701 is blocked. An example is shown in FIG. That is, a game ball that is guided from directly above the winning opening 701 and from the side of the winning opening 701 and contacts the surrounding saving exterior 702 has steps K1 and K2 between the back of the surrounding saving exterior 702 and the back of the transparent plate 55. Therefore, it is not possible to go around to the back side of the peripheral saving outside 702, and therefore, it falls downward from between the nail closest to the winning opening 701 in the nail arrangement 710R and the winning opening cylindrical portion 704.

In the third embodiment, when the game ball is guided to a position apart above the upper obstacle 703 and the game ball is dropped by moving away from the magnet, the dropped game ball is almost vertical due to gravity. Since it falls and collides with the upper surface of the upper obstacle portion 703, it does not enter the winning opening 701 in the manner shown in FIG. However, the possibility that the game ball bounces on the upper surface of the upper obstacle 703 and unexpectedly enters the winning opening is not zero.

  It should be noted that fraudulent acts using the magnets need to be performed in a short time before the hall employee arrives at the crime scene, and it is virtually impossible to try many times. Therefore, it can be said that the configuration of the obstacle according to the third example is sufficiently effective as a countermeasure against fraud.

Next, a fourth embodiment of the present invention will be described with reference to FIGS. In this embodiment, the present invention is applied to a winning device which can win a winning opening only from the side. 35 (a) is a front view of the winning device 750, FIG. 35 (b) is a plan view of the winning device 750 viewed from above, and FIG. 35 (c) is an A view of the winning device 750 shown in FIG. 35 (a). -A sectional view, FIG. 36 (d) is a perspective view of the winning device apparatus 750 as viewed obliquely from the front, and FIG. 36 (e) is a perspective view of the winning device apparatus 750 as viewed from the oblique rear.

In FIG. 35 and FIG. 36, the winning device 750 includes an obstacle portion 756 having a function of preventing fraud using a magnet on the front surface of the winning-port-composing cylinder portion 754 having the winning port 751. The obstacle portion 756 is provided for attaching the surrounding obstacle portion 752 having a shape surrounding the prize opening constituting cylinder portion 754, a roof-like upper obstacle portion 753 covering the top of the prize opening 751, and the winning cylinder 754 to the game board. The peripheral obstacle portion 752 and the upper obstacle portion 753 are integrally formed.

In the winning device 750 having such a configuration, when a game ball enters the winning opening 751, normally, the winning ball 750L or 710R in FIG. The winning portion 751 is entered from the side portion of the space. Since the upper obstacle portion 753 is connected to the substrate 755, it is impossible to enter a game ball from above the winning opening 751.

When an illegal act is performed in which a game ball is attracted by a magnet and guided to the winning hole 751 along the back surface of the transparent plate 55, the gaming ball guided above the winning hole is won by the upper obstacle 753. Entering the ball is blocked. An example of this action will be described with reference to FIG. That is, when the game ball is guided to the position away from the upper obstacle portion 753 of the winning opening 751 by the magnet, and then the game ball is dropped from the transparent plate 55 to drop the gaming ball, After colliding with the upper obstacle 753 that covers the entire upper surface and moving sideways along the roof-like upper obstacle 753, the nail closest to the winning opening 751 in the nail array 710R, It falls downward from between the winning prize port cylinder portion 754.

Further, the game ball guided by the magnet from the lateral direction with respect to the winning opening 751 along the back surface of the transparent plate 55 by adsorbing the game ball by the magnet is prevented from entering by the surrounding obstacle portion 752. The operation at this time will be described with reference to FIG. That is, when a game ball is guided using a magnet directly above the winning opening 751 or from the side of the winning opening 701, the gaming ball that contacts the surrounding obstacle 752 is transparent to the back of the surrounding obstacle 752. The presence of the level difference K with the board 5 prevents the player from going around to the back side of the surrounding obstacle 752, so that when the cheating person gives up and moves the magnet away from the transparent board, the game ball is a winning opening in the nail arrangement 760R. It falls downward from between the nail closest to 751 and the winning port cylinder portion 754.

Next, the game progress control of the first embodiment will be described with reference to FIG. 2, FIG. 16, and FIG. First, the player starts by winning a game ball at the first start winning opening (ST1). However, in the pachinko gaming machine according to the present invention, the game ball must first pass through the first accessory device 14 and then into the second accessory device 19 and finally be released from the discharge port 406. The first start winning opening is never won. Therefore, in this embodiment, the ball does not frequently enter the first start port. If the distribution device is successfully passed and the first start winning opening 20 is won, the determination is YES, and a jackpot random number lottery is executed (ST2). In this embodiment, the jackpot probability is 65532/65536 (see FIG. 17), which is a very high probability. Therefore, if the player enters the first start winning opening 20, he wins the jackpot with a probability of almost 100%. If the jackpot game is won, the jackpot game is played (ST3). The jackpot game of the present embodiment is two rounds, and one round ends when one ball is won in the big prize opening 22, and the number of prize balls is six.

After the jackpot game ends, the game always shifts to the probability change game mode. The jackpot probability in the probability variation game mode is 65533/65536. Also, at this time, an upper limit value N (for example, N = 30) of the probability variation game number between jackpot games is set (ST4). Therefore, the jackpot game will be continued until the number of probable changes reaches the upper limit. Note that the short-time game function is also activated during the probability change game. The short-time game function is specifically an open extension function of the ordinary electric accessory 25. When the game ball passes through the through gate 26, a normal symbol random number lottery is executed. The winning probability is 6/65520 in the normal game, and 65520/65522 in the short-time game. Further, the maximum opening time of the ordinary electric accessory at the time of winning is 0.2 seconds in the normal game, and 5.5 seconds in the short game.

That is, if the short-time game function is not activated, the winning probability is 6/65520 even if the game ball is passed through the through gate, and the opening chance of the second start winning opening 24 is very small. Even if the winning combination is made, the normal electric accessory 25 has an opening time of 0.2 seconds, and it is difficult to enter the game ball into the second start winning opening 24. Therefore, during the so-called normal game, it is almost impossible to win a winning game by putting a game ball into the second winning opening. Therefore, the player has a so-called first jackpot game equivalent to having the game ball enter the first start winning opening 20.

After the jackpot game ends, the probability variation upper limit count is set and stored in the RAM of the main control unit (ST4), and the probability variation game is executed (ST5). If the jackpot game is won in the probability change game (YS in ST6), the value of the continuous probability change count is reduced by 1 (ST7), and the jackpot game is executed (ST8). Until the value of N becomes 0, ST5 to ST8 are repeated (NO in ST9).

That is, if N = 0 (YES in ST9), it is determined whether or not the winning symbol of the last jackpot game is a symbol that shifts to a short-time game after the jackpot game ends (ST10). The probability that the symbol is selected is 1/10. When the jackpot symbol is a symbol that shifts to a short-time game (YES in ST10), the symbol shifts to a short-time game (ST11). In the short-time game, the winning probability of the normal symbol is 65520/65522, and the operating time of the normal electric accessory 25 at the time of winning is 5.5 seconds. Therefore, the game ball can easily enter the second start opening 24. Sphere.

Since the winning probability of the jackpot random number lottery executed when the game ball enters the second starting port is 65532/65536, the winning prize is won by the first winning. If a big hit is made during the short game (YES in ST12), the process returns to ST3 again and the N big hit game continues. On the other hand, the short-time game is executed until the special symbol fluctuates a predetermined number of times (for example, 10 times). The possibility is very close to 0, but if the big win game is not won until the special symbol rotates a predetermined number of times (YES in ST13), the game shifts to the normal game. Further, when the jackpot symbol is not a time-saving symbol in ST10 (NO in ST10), the game shifts to a normal game.

FIG. 18 is a block diagram showing an electrical configuration of the pachinko gaming machine 1 of the present invention. Referring to FIG. 18, control unit 100 includes I / O ports 101A, 101B, and 101C, driver circuits 102, 103, and 104, main control unit 110, sub control units 120 and 130, and relay board 140. including. The I / O ports 101A and 101B are interfaces between the main control unit 110 and the input unit 30, and the I / O port 101C is an interface between the sub control unit 120 and the input unit. The driver circuits 102, 103, and 104 drive the output unit 60 based on commands from the control units 110, 120, and 130.

The input unit 30 includes a first start winning port sensor 31, a second start winning port sensor 32, a large winning port sensor 33, a through gate sensor 34, a normal winning port sensor 35, a first vibration sensor 36, Second vibration sensor 37, first magnetic sensor 38, second magnetic sensor 39, radio wave sensor 40, glass door open / close sensor 41, warp passage 303 passage sensors 42 and 43, rear end opening 210 passage sensor And an introduction part 310 passage sensor and a loss hole 404, 405 passage sensor 46.

The first start prize port sensor 31 is for entering a game ball into the first start prize port 20, and the second start prize port sensor 32 is for entering a game ball into the second start prize port 24. Reference numeral 33 indicates the entry of a game ball into the grand prize opening 22, and the normal prize opening sensor 35 detects the entry of a game ball into the normal prize opening 17. The through gate sensor 34 detects that the game ball has passed through the normal symbol start gate 26.

The 1st vibration sensor 36 and the 2nd vibration sensor 37 are installed in the predetermined position (for example, back side) of the game board 5, and detect the vibration of the illegal pachinko game machine by a player. The first magnetic sensor 38 is installed at a predetermined position (see FIGS. 5 and 9) of the game ball sorting stage 200 in the first accessory device 14 and detects an illegal magnet goto of the player. The 2nd magnetic sensor 39 is installed in the predetermined position (refer FIG. 12) of the frame part in the 2nd accessory apparatus 19, and detects a player's illegal magnet goto. The radio wave sensor 40 is installed at a predetermined position (see FIGS. 12 and 14) on the back side of the sorting stage 400 in the second accessory device 19, and detects an illegal winning detection malfunction by the player. The glass door opening / closing sensor 41 is installed at a predetermined position 75 (see FIG. 2) around the game board, and detects unauthorized opening of the glass door.

The game ball passage sensors 42L and 42R (see FIG. 5) in the warp passages 88L and 88R detect that the game ball has passed through the warp passages 88L and 88R. In other words, it is detected that the game ball has reached the first game ball sorting stage 200 of the first accessory device. The rear end opening 210 passage sensor 44 (see FIG. 7) detects that the game ball has passed through the rear end opening 210 leading to the opening 211 in the first game ball sorting stage 200.

On the other hand, the introduction unit passage sensor 45 (see FIG. 11) detects that the game ball has passed through the front decorative accessory 92 of the second accessory device. In other words, it is detected that the game ball has arrived at the cruising unit 402 of the second accessory device 19. In addition, the loss hole passage sensor 46 indicates that the game ball that has been rotating in the circumferential direction on the clown portion 402 has passed through the loss hole 404 or 405 that cannot enter the second start winning opening. Is detected.

The output unit 60 includes a special symbol display unit 21, a normal symbol display unit 27, a special symbol hold display unit 28, a normal symbol hold display unit 29, and a normal electric accessory (second start prize opening opening / closing plate) drive unit. 61, a special electric accessory (large winning opening opening / closing plate) driving unit 62, speakers 11, 12, and various effect lamps L1, L2. The ordinary electric accessory driving unit 61 opens and closes the opening / closing plate 25 shown in FIG. The special electric accessory driving unit 62 opens and closes the opening / closing plate 23 of the special winning opening 22.

The main control unit 110 is for controlling the basic operation of the game in the pachinko gaming machine 1, and operates as a lottery means, a special game transition means and a special game execution control means, and a jackpot random number or program software Etc., and a microcomputer including a RAM 113 as a temporary storage area. The RAM 113 includes a probability variation remaining number storage unit.

Based on the signal input from the input unit 30 via the I / O port 101A or 101B, the main control unit 110 sends a command, illegal information, data, or the like according to the random number lottery result via the relay board 140. A special symbol display unit 21, a normal symbol display unit 27, a special symbol hold display unit 28, and a normal symbol hold display unit included in the output unit 60 via the driver circuit 102 in one direction. 29, a control signal is given to the ordinary electric accessory (second start winning opening opening / closing plate) driving section 61 and the special electric combination (large winning opening opening / closing plate) driving section 62. In addition, when an illegal signal is received, a command for executing a warning by sound or lamp is transmitted to the sub-control unit 120 or 130.

The CPU 111 that operates as a lottery means acquires various random values on condition that the game ball has entered the first starting winning port 20 or the second starting winning port 24, and whether the acquired random number value matches the jackpot random number. Determine whether or not. The CPU 111 operating as a special game state transition means shifts to a jackpot game that is advantageous to the player on condition that the acquired random number value matches the jackpot random number in the random number lottery.

The sub-control units 120 and 130 execute a game excitement effect based on a signal input from the input unit 30 via the I / O port 101C. For example, when the sensor 42L or 42R detects that the game ball has passed through the warp passage 88L or 88R, it means that the game ball has reached the first sorting stage, which means that one step has come close to the jackpot. Each of the CPUs 121 and 131 of the sub-control units 120 and 130 gives a sound and light effect informing the player that one step has come close to the jackpot through the driver circuits 103 and 104 to the speakers 11 and 12 and the lamps L1 and L2. It is executed until time or a predetermined condition is satisfied.

In addition, if the rear end opening 210 passage sensor 44 detects the passage of the game ball, the sub-control units 120 and 130 are required to reach the first start winning opening directly connected to the big hit game winning. Since the possibility of entering the accessory device has expanded, the loudspeaker 11 and 12 can produce a flashy sound and light effect that further enhances expectations compared to when the game ball passes through the warp paths 88L and 88R. The lamps L1 and L2 are executed for a predetermined time or until a predetermined condition is satisfied.

In addition, if the introduction unit 301 passing sensor 45 detects the passing of the game ball, the sub-control units 120 and 130 are required to reach the first start winning opening directly connected to the big hit game winning. More than when the rear end opening 210 passage sensor 44 detects the passage of the game ball in response to the fact that the game ball has entered the device and has reached the cleon 402 of the second game ball sorting device 400. Further, flashy sound and light effects that further increase the sense of expectation are executed on the speakers 11 and 12 and the lamps L1 and L2 until a predetermined time or a predetermined condition is satisfied.

On the other hand, if the game ball that has reached the cruising portion 402 of the second game ball sorting device 400 moves circumferentially while gradually approaching the center, if the ball enters the lost hole, the lost hole 404, 405 passage sensor In response to the signal from 46, the sub-controllers 120 and 130 cause the speakers 11 and 12 and the lamps L1 and L2 to execute a disappointing effect by sound and light for a predetermined time or until a predetermined condition is satisfied. On the other hand, the game ball that has entered the winning hole 403 enters the first start winning opening, and in that case, it is almost 100% big hit, so the sub-control unit 120 that received the big hit winning information from the main control unit 110, 130 executes a jackpot effect by sound and light on the speakers 11 and 12 and the lamps L1 and L2 for a predetermined time or until a predetermined condition is satisfied.

FIG. 38 and FIG. 39 are modified embodiments of the pachinko gaming machine according to the present invention, and for the purpose of facilitating maintenance work such as ball clogging of the winning opening and adjustment of the distance between obstacle nails, an obstacle is awarded during maintenance. The structure which can be evacuated by simple operation from the upper part of the entrance of a mouth is shown. FIG. 38 is a front view showing a lower part of the second accessory device 19 shown in FIGS. 22 to 26, and FIG. 39 is a cross-sectional side view taken along the line CC in FIG. In these drawings, the portions denoted by the same reference numerals as those in FIGS. 22 to 26 indicate the same members and the same parts, respectively.

A U-shaped notch 363 is provided at the lower end of the frame portion 92 of the second accessory device 19 shown in FIG. 38, and is formed separately from the frame portion 92 in the notch 363. A tongue-like protruding portion 362 ′ is rotatably accommodated. The projecting portion 362 ′ has a plate shape in which a rectangular base end portion accommodated in the notch 363 and a substantially inverted trapezoidal tip portion projecting downward from the outline of the frame portion 92 are integrally formed. A second hole 352 is formed at the center in the same manner as described with reference to FIGS.

The relationship between the distance between the lower end and the obstacle nails 341L and 341R is the same as that described with reference to FIGS. 22 to 26, and the description thereof is omitted here.

The pachinko gaming machine of the present embodiment has the above-described configuration in general, but during the game, the projection 366 of the projection 362 ′ is engaged with the inner surface of the transparent plate 55 of the closed front door 3, and the projection The angle position of 362 ′ is held so that the back surface is parallel to the back surface of the transparent plate 55, that is, the angle position shown by the solid line in FIG. The game ball that has passed through the guide path 408 and is released from the discharge port 406 into the game space S in front of the game board 5 collides with the back surface of the protrusion 362 'and changes its direction downward, with almost 100% probability. To enter the first start winning opening 20.

If a ball employee uses the key to open the front door 3 when a ball clog occurs between the first start winning opening 20 and the obstacle nails 341L and 341R during the game, the protruding portion 362 'Is because the lower end pivots forward as shown by a two-dot chain line in FIG. 39 due to the action of the urging spring and retracts from the entrance of the first start winning opening 20 formed by the obstacle nails 341L and 341R. The ball clogging elimination operation for the obstacle nails 341L and 341R and the first start winning opening 20 can be immediately executed.

When the nail adjustment work is performed on the obstacle nails 341L and 341R immediately before factory shipment from a pachinko machine manufacturer to the hall, the game board 5 side is opposed to the urging force of the urging spring. 39, the bottom end of the projecting portion 362 'largely retracts backward from the head of the obstacle nail 341L, 341R, so that the nail adjustment with respect to the obstacle nail 341L, 341R is performed. Can be easily performed.

When the maintenance for the first start winning opening 20 and the obstacle nails 341L and 341R is completed and the front door 3 is closed as it is, the inner surface of the transparent plate 55 of the front door 3 is the swing end of the protruding portion 362 ′. , And the protrusion 362 ′ is retracted to the position indicated by the solid line in FIG. 39 against the biasing force of the spring, so that the protrusion 362 ′ can be easily returned to the original position by a magnet. A function to prevent illegal entry can be exhibited. The condition that the protrusion 362 ′ automatically rotates to the original position when the protrusion 362 ′ and the transparent plate 55 abut each other is that the standby angle of the protrusion 362 ′ is the entrance angle of the transparent plate 55. In other words, it is necessary to generate a rotational moment opposite to the spring biasing direction X with respect to the horizontal direction. Therefore, in this embodiment, the forward rotation angle of the projecting portion 362 ′ is defined as an angle range of about 75 ° or less forward from the state parallel to the game board 5. In the above-described embodiment, the case where the present invention is applied to the lower part of the second accessory device 19 has been described. However, the present invention can be similarly applied to the first accessory device 14.

In the above embodiment, the tongue-shaped protruding portion 362 ′ is formed separately from the frame portion 92, and is attached to the frame portion 92 so as to be rotatable about the shafts 364L and 364R. Although the configuration has been disclosed, the configuration of the protrusion 362 'is not limited to this. For example, as shown in FIGS. 11 and 12, the protrusions 362 are integrally formed with the frame part 92 by a transparent synthetic resin having flexibility and elasticity, and on both sides of the base part of the protrusions 362. A slit is formed in the vertical direction so that the protruding portion 362 is easily bent from the base, and the lower end of the protruding portion 362 is protruded forward or retracted backward by pushing and pulling the protruding portion 362 by hand. It is also possible to facilitate maintenance of the one-start winning port 20.

That is, it is held at the angular position indicated by the solid line in FIG. At this time, the step K1 between the back surface of the obstacle 702 around the obstacle 706 and the back surface of the transparent plate 55 has such a size that the game ball sucked to the transparent plate 55 by the magnet cannot get over, and A level difference K2 between the back surface of the upper obstacle portion 703 and the back surface of the transparent plate 55 has a size that prevents the game ball attracted to the transparent plate 55 by the magnet from going around the obstacle 706. Therefore, the fraudulent act of attracting the game ball using the magnet and guiding it to the winning hole 701 along the back surface of the transparent plate 55 is blocked by the surrounding obstacle portion 702 and dropped from the upward direction with respect to the winning hole 701. The game ball is blocked by the upper obstacle 703 from entering.

In addition, when a ball clog occurs between the winning opening 704 and the obstacle nails 708L and 708R during the game, when the hall employee opens the front door 3 using a key, the obstacle 706 is not shown. As shown by a two-dot chain line in FIG. 40B, the upper end pivots forward by the action of the urging spring, and the upper obstacle portion 703 of the upper end is formed by the obstacle nail obstacle nail 708L, 708R. Since the upper part of the entrance is retracted forward, the ball clogging eliminating operation for the obstacle nails 708L and 708R and the winning opening 704 can be immediately executed.

Also, when the nail adjustment work for the obstacle nails 708L and 708R is performed before the factory shipment of the pachinko gaming machine to the hall, the obstacle 706 is caused by the biasing force of the spring only by opening the front door 3. Therefore, the nail adjustment to the obstacle nails 708L and 708R can be easily performed.

When the maintenance on the winning opening 704 and the obstacle nails 708L and 708R is completed and the front door 3 is closed as it is, the inner surface of the transparent plate 55 of the front door 3 is engaged with the upper end of the obstacle 706, Since the object 706 is retracted to the position indicated by the solid line in FIG. 40B against the biasing force of the spring, it is possible to easily return the obstacle 706 to the original position and prevent illegal entry by the magnet. The function to perform can be demonstrated.
