Description

  The present invention relates to a ball game machine such as a pachinko machine or an arrangement ball machine.

  For example, in a pachinko machine, an approximately circular game area is formed between a guide rail on the front surface of a game board and a decorative member, and a liquid crystal type image display means is provided in the approximate center of the game area. Is arranged. A left-handed passage and a right-handed passage are provided on both the left and right sides of the game area, with a central player in between. Normally, a left-handed strike is made by concentrating game balls in the left-handed passage. By making a right hit to concentrate the game ball in the aisle and passing the game ball to the starting means in the right hit passage, a special profit state (a big win) that the variable winning means is released is likely to occur. (Patent Document 1).

  In addition to providing starting means in the right-handed passage, a number of game nails are provided in front of the game board so that the game balls entering the right-handed passage fall in a complicated manner. However, when the game ball moves in a complicated manner, if a game ball that has passed through the starter and a game ball that has fallen through other than the starter collide near the lower side of the starter, the game ball that has passed through the starter May jump to the starting means side by the impact at that time, and may cause a malfunction that is detected again by the detecting switch of the starting means.

  Therefore, conventionally, a plurality of game nails are arranged on the lower side of the starting means, and the game balls that have passed through the starting means and the game balls that have passed through other locations are below the starting means by the plurality of game nails. We try not to interfere in the vicinity.

  However, since conventional pachinko machines have a structure in which a plurality of game nails are arranged below the starting means to prevent mutual interference of game balls, the work for assembling the game board is very complicated, and There is a drawback that variations tend to occur.

  This is because, in recent pachinko machines, the image display means tends to be very large, and the right-handed passage tends to become narrower as the image display means becomes larger. Therefore, when assembling the game board, it is necessary to hit the game nail in advance on the game board corresponding to the narrow right-handed passage, and then assemble the central actor and starting means at a predetermined position on the game board while avoiding the game nail. In addition, there is a drawback that work is very complicated and work efficiency is lowered. In addition, since the starting means and the plurality of game nails are separate, there is a disadvantage that the positional relationship among the central character, the starting means and the game nails is likely to vary for each game board and cannot be made uniform.

The present invention, such view of the conventional problems, with the work of assembling the game board is improved easy work efficiency, to provide a ball-shooting game machine which can standardize the work during Assemble viewed With the goal.

The present invention is provided with a passing gate having a detection switch for detecting the passing of a game ball in a fall passage between gaming parts mounted on the front surface of the game board, and passes through the passing gate below the passing gate. In a ball game machine in which an interference preventing means for preventing interference between a game ball and a game ball that has fallen through other than the pass gate is disposed, the pass gate includes a holding frame that holds a detection switch , and one of the games part has a guide part for the draft game balls passing between the said passgate to the other of said game component side at the lower side of the pass gate, wherein the interference preventing means in the lateral direction of the holding frame on the other hand those having an interference prevention plate for a draft game balls having passed through and the passgate provided integrally on a side to the other game component side.

According to the present invention, the work of assembling the game board is improved easy work efficiency can be advantageously standardize the work during Assemble seen.

  Hereinafter, a first embodiment of the present invention will be described in detail with reference to the drawings. 1 to 4 illustrate a first embodiment in which the present invention is employed in a pachinko machine. As shown in FIG. 1, the pachinko machine includes a rectangular outer frame 1 and a front frame 3 pivotally attached to a front side of the outer frame 1 by a hinge 2 so as to be openable and closable around a vertical axis. A glass door 4 and a front plate 5 are arranged vertically on the front side of the front frame 3 and are pivotally supported by a hinge 6 on the same side as the hinge 2 with respect to the front frame 3 so as to be openable and closable around the vertical axis.

  On the front side of the front plate 5, a ball supply tray 7 for storing a game ball for launch is arranged, and a launch handle 8 of launch means (not shown) for launching the game ball is provided on the side thereof. A game board 10 is detachably mounted on the front frame 3 on the back side of the glass door 4 so as to correspond to the glass door 4.

  On the front surface of the game board 10, a guide rail 11 for guiding a game ball launched from the launching means and a substantially arc-shaped decoration member 12 are attached in the circumferential direction, and the guide rail 11 and the inner peripheral wall of the decoration member 12 are mounted. A game area 14 having a substantially circular shape is formed on the inside of the game area 13. The guide rail 11 has an inner rail 11a and an outer rail 11b, and a game area 14 is defined by the inner rail 11a, a part of the outer rail 11b, and an inner peripheral wall 13 of a decorative member (game part) 12. .

  In the game area 14, there are a central character (game part) 15, a normal symbol starting means 16, a first special symbol starting means 17, a second special symbol starting means 18, a jackpot opening / closing prize winning means 19, and normal winning means 20, 21. Various game parts such as a normal symbol display means 22, a first special symbol display means 23, a second special symbol display means 24, and a decorative body are arranged.

  The central actor 15 is provided with an image display means 25 and is arranged at the approximate center in the left-right direction of the game area 14. The left side of the central actor 15 is a left-handed passage 26 and the right side is a right-handed passage 27. . Therefore, the game balls that are driven into the upper portion of the game area 14 sequentially fall through any one of the left-handed passage 26 and the right-handed passage 27.

  The central accessory 15 has a front decorative frame 28 protruding forward from the game board 10, and is attached to the game board 10 via an attachment base 32 that abuts the front surface of the game board 10. The mounting base 32 is common to the central accessory 15, the normal symbol starting means 16, and the open / close winning means 19, and extends to the right-handed passage 27 side to the vicinity of the inner peripheral wall 13 of the decorative member 12. In addition, a normal symbol starting means 16 and an open / close winning means 19 are provided. The image display means 25 is a liquid crystal type or the like, and is provided corresponding to the display window of the front decoration frame 28.

  The first special symbol starting means 17 and the second special symbol starting means 18 are vertically arranged between the central accessory 15 and the lowermost outlet ball opening 29 at the center of the left and right of the lower side of the central accessory 15. Is arranged. A plurality of normal winning means 20 are arranged with a left-handed passage 26 on the lower left side of the central accessory 15, and a normal symbol starting means 16 is arranged in a right-handed passage 27 on the right side. On the lower right side of the accessory 15, an open / close winning means 19 and a normal winning means 21 are arranged.

  The front decoration frame 28 has a ball guide opening 28a that opens to the left-handed passage 26 side, and a game ball guided through the ball guide opening 28a is moved to the front side of the game board 10 in the vicinity of the upper part of the first special symbol starting means 17. And a normal symbol display means 22, a first special symbol display means 23, and a second special symbol display means 24 are mounted at appropriate locations on the front side.

  The normal symbol display means 22 is for variably displaying normal symbols, and is composed of a plurality of light emitting elements corresponding to a plurality of types of normal symbols (for example, two types of “O” and “X”). Under the condition that the starting means 16 detects a game ball, the two light-emitting elements blink for a predetermined time so that they are alternately turned on, and a random number value that is randomly drawn when the normal symbol starting means 16 detects the game ball is determined in advance. The light emitting element on the “◯” side in the hit state is turned on when the hit determination value is matched, and the light emitting element on the “×” side in the off state is turned on and stopped in other cases. In addition, the normal symbol after change will be in a hit mode with a predetermined probability of about 1/10.

  The first special symbol display means 23 and the second special symbol display means 24 are constituted by display means such as a segment type capable of variably displaying the first special symbol and the second special symbol due to a change in the light emitting part, etc. The special symbol display means 23 is detected by the first special symbol start means 17, and the second special symbol display means 24 is detected by the second special symbol start means 18 by the second special symbol start means 18. When the symbol fluctuates for a predetermined time and the random number value lottery when the first special symbol starter 17 and the second special symbol starter 18 detect the game balls matches the predetermined jackpot determination value, the predetermined jackpot In the mode, it is stopped in the off mode in other cases.

  Note that the first special symbol and the second special symbol after the change are in a big hit mode with a normal probability of 1/350 etc. during the normal probability state, and a high probability of 1/35 etc. in the high probability state after the big hit state ends. It becomes a big hit mode. Neither the first special symbol nor the second special symbol changes when the big hit state is in effect, and the other does not change when one is changing. Further, the start detection of each special symbol can be suspended up to a predetermined upper limit number (for example, 4), and when both have one or more suspensions, the symbol variation of the second special symbol display means 24 has priority. Furthermore, during the high probability state, the variation time of the first special symbol and the second special symbol is also shortened.

  The image display means 25 constitutes the effect symbol display means 30 corresponding to the first special symbol display means 23 and the second special symbol display means 24. When the first special symbol and the second special symbol change, the image change means 25 One or a plurality of, for example, three effect symbols 30a to 30c that fluctuate synchronously are variably displayed. The effect symbols 30a to 30c change for a predetermined time through a predetermined effect symbol variation pattern determined by lottery on the condition that the first special symbol starter 17 and the second special symbol starter 18 detect the game balls. It stops sequentially in a predetermined order in synchronization with the end of the fluctuation of the first special symbol and the second special symbol. The effect symbol display means 30 may be provided separately corresponding to the first special symbol display means 23 and the second special symbol display means 24.

  When the first special symbol and the second special symbol are stopped in the big win mode, the stop symbol after the change of the directing symbols 30a to 30c becomes a big hit directing mode in which the first special symbol and the second special symbol come off. In the case of stopping in a mode, at least a part is a different production mode.

  For example, numerical symbols from 0 to 9 are used for the production symbols 30a to 30c, and when the special symbols are stopped in a big win mode, the production symbols 30a to 30c are jackpot productions such as "7 / 7.7". When it stops in the mode and the special symbol stops in the off mode, the effect symbols 30a to 30c stop in the off mode such as “2, 4, 5”.

  The first special symbol starting means 17 is a non-opening / closing type, and is disposed below the image display means 25. The first special symbol starting means 17 has a left-handed passage 26 compared to a right-handed passage 27. Game balls that fall after that are easier to win.

  The second special symbol starting means 18 is an open / close type, and is constituted by an electric tulip type winning means having a pair of left and right opening / closing members 18a, etc., and the normal symbol after the fluctuation of the normal symbol display means 22 stops in a hit state. In some cases, it is opened with a predetermined opening pattern.

  The opening pattern of the second special symbol starting means 18 includes a normal pattern with a short opening time (for example, 0.2 seconds × 1 time) and a special pattern with a long opening time (for example, 2 seconds × 3 times). A normal pattern is selected during the state, and a special pattern is selected during the high probability state.

  The open / close winning means 19 has a front decoration frame 37 projecting forward from the mounting base 32 at the lower part of the right-handed passage 27. The front decoration frame 37 divides the lower portion of the right-handed passage 27 into an upper passage 33 and a lower passage 34, and a large winning opening 36 that is opened and closed by an opening / closing plate 35 is provided corresponding to the upper passage 33. Yes.

  The open / close plate 35 closes the grand prize opening 36 when moving forward and guides the game balls in the upper passage 33 to the special symbol starting means 17, 18. It is possible to leave in the front-rear direction to win the big prize opening 36. The special winning opening 36 is open on the upper passage 33 side.

  The open / close winning means 19 opens and closes in a predetermined opening pattern during the big hit state that occurs when the first special symbol and the second special symbol after the change stop in a big win mode. When winning, more prize balls are paid out than winning in other ordinary winning means 20, 21 or the like.

  The opening / closing pattern of the open / close winning means 19 is an opening / closing operation that closes an opening / closing operation of closing a predetermined number (for example, 10) of game balls or winning a predetermined time (for example, 30 seconds), whichever comes first. There are a plurality of types of rounds depending on the number of rounds, and one of the plurality of types of opening / closing patterns is drawn at the time of the jackpot lottery.

  The normal symbol starting means 16 is for changing the normal symbol of the normal symbol display means 22 on the condition that the game ball is detected, and is constituted by a passing gate through which the game ball falling through the right-handed passage 27 can pass.

  This normal symbol starting means 16 and its peripheral part are configured as shown in FIGS. That is, the inner peripheral wall 13 of the decorative member 12 is formed in a substantially arc shape. On the other hand, the front decorative frame 28 of the central accessory 15 is provided with adjacent walls 39 and 40 disposed in the vicinity of the inner peripheral wall 13 of the decorative member 12 on both the upper and lower sides of the normal symbol starting means 16, and the upper and lower adjacent walls thereof. A spacing wall 41 that is spaced from the inner peripheral wall 13 of the decorative member 12 to the inside of the game area 14 is provided between 39 and 40.

  Therefore, the right-handed passage 27 has narrow passage portions 42 and 43 on both the upper and lower sides and a wide passage portion 44 between the narrow passage portions 42 and 43, and the wide passage portion 44 has a large number of normal symbol starting means 16. It is arranged together with the game nail 45. The wide passage portion 44 has an inner passage portion 46 between the normal symbol starting means 16 and the spacing wall 41 of the front decorative frame 28, and an outer passage portion between the normal symbol starting means 16 and the inner peripheral wall 13 of the decorative member 12. 47 is formed, and while the game ball falling from the upper narrow passage portion 42 is guided by a large number of game nails 45, the lower side passes through any one of the normal symbol starting means 16, the inner passage portion 46, and the outer passage portion 47. It moves to the narrow passage portion 43.

  The separation wall 41 of the front decorative frame 28 is formed from an upper guide portion 41a that is recessed in a gentle arc shape from an upper position of the normal symbol starting means 16 to the inside of the normal symbol starting means 16, and from a lower end of the upper guide portion 41a. It has a lower guide portion 41b that curves downward to the lower side of the normal symbol starting means 16 and extends in the left-right direction through the lower side of the normal symbol starting means 16 to the neighboring wall 40 close to the inner peripheral wall 13 of the decorative member 12. For this reason, the lower side of the inner passage portion 46 is curved outward toward the inner peripheral wall 13 of the decorative member 12 below the normal design starting means 16.

  The wide passage portion 44 has a substantially vertically long circle or water droplet shape in which the left-right width on the lower side is wider than the left-right width on the upper side, and the mounting base 32 is mounted on the lower side from the approximate center in the vertical direction. A number of game nails 45 are provided above the base 32. The lower end portion 42a of the upper narrow passage portion 42 is provided at the approximate center in the left-right direction of the wide passage portion 44 by the vicinity wall 39 of the front decorative frame 28 and the guide protrusion 48 disposed to face the wall 39. Yes.

  The normal symbol starting means 16 is disposed on the front decoration frame 28 side of the lower end portion 42 a of the upper narrow passage portion 42, and the wall 40 near the lower narrow passage portion 43 is from the normal symbol starting means 16. Also protrudes toward the inner peripheral wall 13 side of the decorative member 12.

  As shown in FIGS. 2 to 4, the normal symbol starting means 16 has a passage port frame 49 that protrudes integrally from the mounting base 32 toward the front side, and is formed in the passage port frame 49 in a vertically penetrating manner. A passage 50 that can pass through and a detection switch 51 that detects a game ball passing through the passage 50 are provided. The detection switch 51 includes a flat main body in which an opening corresponding to the passage opening 50 is formed. The main body is inserted into a holding groove in the passage opening frame 49 and is detachably fixed by an engaging claw 52. The detection switch 51, the engaging claw 52 and the like protrude rearward from the mounting base 32 and are inserted into a through hole 53 formed in the game board 10.

  The normal symbol starting means 16 is provided with an interference preventing means 54 on the lower side thereof. By this interference preventing means 54, a game ball that has passed through the normal symbol starting means 16 and a game ball that has fallen through other than the normal symbol starting means 16 can be used. The interference in the vicinity of the lower side of the normal symbol starting means 16 is prevented.

  As shown in FIGS. 2 to 4, the interference preventing means 54 guides the game ball that has passed through the passage opening 50 of the normal symbol starting means 16 to one of the same left and right directions as the lower guide portion 41b above the lower guide portion 41b. The inner passage portion 46 is provided between the interference prevention plate 55 and the guide portions 41a and 41b.

  The interference prevention plate 55 is integrally extended from the passage port frame 49 to the lower side on the central agent 15 side with respect to the passage port 50, and the inner peripheral wall 13 of the decorative member 12 from the lower end of the vertical plate portion 55a. It is configured in an L shape in front view having a horizontal plate portion 55b that is bent in an arc shape outward in the left-right direction, and is integrally formed across the passage opening frame 49 and the mounting base 32.

  The front end of the horizontal plate portion 55b is closer to the decoration member 12 than the end of the passage opening 50 of the normal symbol starting means 16 on the decoration member 12 side, and the game ball is placed below the decoration member 12 from the passage opening 50. The ball is dropped to the narrow passage portion 43, and the game ball is prevented from returning to the passing port 50 side even when it collides with the game ball dropped through the outer passage portion 47.

  During the game, the launching means is operated to launch a game ball into the game area 14. At this time, if in the normal probability state, the player hits the left so that the game balls concentrate on the left-handed passage 26 that is easy to win the first special symbol starting means 17. If the game ball wins the first special symbol starting means 17 through the ball guide port 28a, the ball dropping portion 28b, etc. of the central actor 15 while falling in the left-handed passage 26, the first special symbol display means 23 The effect symbols 30a to 30c of the 1 special symbol and effect symbol display means 30 fluctuate for a predetermined time in synchronization. Then, depending on whether or not the lottery result when the game ball wins the first special symbol starting means 17 is a big win, the first special symbol after the change of the first special symbol display means 23 is a big hit mode or a miss The effect symbols 30a to 30c of the effect symbol display means 30 are stopped in the jackpot effect mode or the off effect effect mode.

  If a game ball that has entered the right-handed path 27 wins the normal symbol starting means 16 even in the normal probability state, the normal symbol of the normal symbol display means 22 may fluctuate and stop in a hit state after the fluctuation. However, since the opening time of the second special symbol starting means 18 is very short during the normal probability state, the possibility that the game ball wins the second special symbol starting means 18 is very low.

If the first special symbol after the change of the first special symbol display means 23 stops in a big win mode, it becomes a big hit state, and the open / close winning means 19 repeats a predetermined round number opening / closing operation with a predetermined open / close pattern, so that the player The player hits the open / close winning means 19 in order to concentrate the game balls on the side of the right-handed passage 27 where the game balls can easily win.

  The game ball that has entered the right-handed passage 27 wins the normal symbol starting means 16 or falls downward without winning, and then passes through the upper passage 33 to the special symbol starting means 17, 18 side or the lower passage 34. After that, it flows down to the ball outlet 29 side. In the case of a big win, the winning prize opening 36 that opens and closes with a predetermined opening / closing pattern is won.

  The game ball that has entered the right-handed passage 27 passes through the narrow passage portion 42 along the decorative member 12 and falls from the lower end portion thereof to the wide passage portion 44. The wide passage portion 44 has a large number of game nails 45 on the upper side of the normal symbol starting means 16, and the game ball falls while colliding with the game nails 45 and enters the passing port 50 of the normal symbol starting means 16. The inside passage portion 46 between the normal symbol starting means 16 and the central accessory 15 or the outer passage portion 47 between the normal symbol starting means 16 and the decorative member 12 is entered.

  When a game ball enters the passage 50 of the normal symbol starting means 16, the detection switch 51 detects the passage of the game ball, and the normal symbol of the normal symbol display means 22 fluctuates for a predetermined time and stops in a hit state or a disengagement mode. . And when it stops in a hit mode, the 2nd special symbol starting means 18 opens and closes with a predetermined opening / closing pattern, and it becomes easy to win a game ball to the 2nd special symbol starting means 18.

  The game ball guided to the upper guide portion 41a side of the central actor 15 by colliding with the game nail 45 or the like enters the inner passage portion 46 along the upper guide portion 41a, and from the upper guide portion 41a to the lower guide portion. After being guided to the outside in the left-right direction by the lower side of the normal symbol starting means 16 by 41b, it falls from the tip of the lower guide portion 41b to the narrow passage portion 43.

  However, there is an interference prevention plate 55 that is curved in a substantially L-shape when viewed from the front side below the normal symbol starting means 16, and the game ball that has passed through the normal symbol starting means 16 by the interference prevention plate 55 is passed through the inner passage portion 46. Since these are guided separately from the game balls passing through, the game balls do not normally interfere with each other under the symbol starting means 16.

  That is, the game ball that has passed the normal symbol starting means 16 is guided through the upper side of the interference prevention plate 55, and the game ball that has entered the inner passage portion 46 is guided along the lower guide portion 41b below the interference prevention plate 55. Therefore, the collision of the game balls with each other can be prevented. Accordingly, it is possible to prevent erroneous detection of the game ball of the detection switch 51 which has conventionally occurred due to the collision of the game ball near the lower side of the normal symbol starting means 16.

  Although the game ball may fall through the outer passage portion 47, the tip of the interference prevention plate 55 extends to the decorative member 12 side from the passage opening 50 of the normal symbol starting means 16, so that the normal symbol starting means 16 is Even if the passed game ball collides with the game ball falling through the outer passage portion 47, the detection switch 51 does not erroneously detect the game ball.

  The mounting base 32 is common to the central accessory 15, the normal symbol starting means 16 and the opening / closing prize winning means 19, and the interference preventing means 54 is provided on the mounting base 32, so that the central accessory 15 and the normal symbol starting means 16 are provided. Relative position between the normal symbol starting means 16 and the interference preventing means 54 can be determined uniformly, and the assembly work of the game board 10 can be facilitated, and positional variations can be prevented as much as possible. .

  The central accessory 15 guides the game ball that has passed through the inner passage portion 46 between the normal symbol starting means 16 to the inner peripheral wall 13 side that is one of the left and right directions below the normal symbol starting means 16. The interference prevention means 54 has an interference prevention plate 55 that guides the game ball that has passed through the normal symbol starting means 16 to one side in the same lateral direction as the lower guide part 41b above the lower guide part 41b. Therefore, not only can the interference of the game balls that have passed through each other be prevented, but the game balls can be guided to the outside of the game area 14, and the normal symbol starting means 16, the lower guide portion 41 b, and the interference prevention means 54 are provided in the game area 14. In combination with the right-handed passage 27 being arranged at the substantially central portion in the vertical direction, a sufficient distance to the out ball port 29 can be secured.

  Further, the normal symbol starting means 16 includes a mounting base 32 and a passing port frame 49 which projects from the mounting base 32 to the front surface and has a passing port 50 through which a game ball passes. The mounting base 32 and the passing port frame 49 are provided. By providing the interference prevention means 54 and, particularly, the interference prevention plate 55, the passage opening frame 49 and the interference prevention plate 55 are reinforced with each other, and damage to the interference prevention plate 55 can be easily prevented. . Moreover, by providing the passage port frame 49 and the interference prevention plate 55 integrally with the mounting base 32, both can be easily arranged in an optimal positional relationship with a simple structure.

  5 and 6 illustrate a second embodiment of the present invention. In this embodiment, the passage base frame 49 of the normal symbol starting means 16 and the interference preventing plate 55 of the interference preventing means 54 are vertically fixed on the mounting base 32 common to the central accessory 15 and the normal symbol starting means 16. A space A is provided. The interference prevention plate 55 is provided in an arc shape from a lower position near the inner passage portion 46 of the passage opening frame 49 to a lower position near the outer passage portion 47 of the passage opening frame 49. The distance A between the passage opening frame 49 and the upper end of the interference prevention plate 55 is less than the diameter of the game ball, approximately the diameter of the game ball, or slightly larger than the diameter of the game ball. Other configurations are the same as those of the first embodiment.

  Even if there is an interval A between the passage opening frame 49 and the upper end of the interference prevention plate 55, the game balls fall downward on both sides of the interval A portion, so that they do not interfere with each other. Therefore, when the interference preventing means 54 is provided in the normal symbol starting means 16, it is provided integrally with the mounting base 32 with a predetermined interval A between the passage opening frame 49 and the interference preventing plate 55 as in this embodiment. May be.

  FIG. 7 illustrates a third embodiment of the present invention. In this embodiment, an interference preventing plate 55 is provided below the passage opening frame 49 of the normal symbol starting means 16 corresponding to the inclined guide portion 57 of the central accessory 15. The inclined guide portion 57 is normally inclined to the symbol starting means 16 side, and normally falls after falling in the direction indicated by the arrow b after the game ball falling in the direction indicated by the arrow a collides.

  Even in such an inclined guide portion 57, when a game ball collides in the direction indicated by the arrow c with a strong impact force, the game ball may fly to the lower side of the normal symbol starting means 16 in the direction indicated by the arrow d. If the game ball collides with the game ball immediately after passing through the passage opening 50 of the normal symbol starting means 16, there arises a problem that the detection switch 51 is erroneously detected. Accordingly, the interference preventing means that protrudes downward in the vicinity of the inner passage portion 46 side of the passage opening frame 49 so that the game ball from the inclined guide portion 57 does not fly near the lower side of the passage opening 50 of the normal symbol starting means 16. It is sufficient to provide some obstacle protrusion such as 54.
