A guide passage 118 (see FIG. 1) is formed, and the foul sphere flows out to the surplus sphere guide passage (not shown) on the back side through the foul ball port 116 and then returned to the surplus sphere receiving tray 4. It has become so. Further, in the vicinity of the foul ball guide passage 118, a ball removal guide passage (not shown) for guiding the standby ball that has flowed out from the hit ball supply tray 3 through the ball discharge port 113a to the ball discharge communication port 106 is formed. These foul balls and standby balls flow out to the surplus ball guide passage (not shown) through the guide passage communicating with the foul ball opening 116 and the ball discharge communication opening 106.

  A pachinko ball launched from a hitting ball launching device (game ball launching device) (not shown) by a player's operation is guided by the hitting ball guide rail 117 (see FIG. 1), and then the inner rail 42 and the outer rail 43 are guided. Enters the game area 7 through the hitting ball guide passage 45 formed between the two and then descends the game area 7.

  When the pachinko ball that has entered the game area 7 enters the first start port 15a and is detected by the first start port switch 14a, or enters the second start port 15b and is detected by the second start port switch 14b, If the special symbol variation display can be started, the special symbol display unit 8 starts the variable symbol variation display. If the special symbol variable display is not ready to start, the number of reserved memories is increased by one.

  The variation display of the special symbol on the special symbol display 8 stops when the variation display time set every time the variation display is performed. If the special symbol (stop symbol) at the time of stoppage is a jackpot symbol (also referred to as a jackpot display result) as a specific display result, it will be a jackpot and the game will shift to a jackpot gaming state. In the big hit gaming state, the special variable winning ball device 20 is released until a predetermined time elapses or a predetermined number (for example, ten) of pachinko balls wins. Then, if the pachinko ball wins the V winning area while the special variable winning ball apparatus 20 is opened and is detected by the count switch 23, a continuation right is generated and the special variable winning ball apparatus 20 is opened again. The generation of the continuation right is allowed with a predetermined number of times such as 15 rounds as an upper limit value. Such control is called repeated continuation control. In the repeated continuation control, a state in which the special variable winning ball apparatus 20 is opened is called a round. In addition, you may control not to provide V winning area but to generate a continuation right unconditionally in each round.

  If the special symbol on the special symbol display 8 at the time of stoppage is a predetermined special big-hit symbol (probable variation big-hit symbol) among the big-hit symbols (probability big-hit symbol) ) Becomes a more advantageous state for the player, a probability variation state (hereinafter referred to as a probability variation state) that becomes higher than the normal gaming state, which is a normal state different from the big hit gaming state. Hereinafter, the probability variation state is also referred to as a high probability state (sometimes abbreviated as a high probability state). Further, the non-probable change state is also referred to as a low probability state (sometimes abbreviated as a low probability state).

  In addition, when the display result of the special symbol when the variable display on the special symbol display 8 is stopped is the probability variation big hit symbol, the variable time is reduced after the big hit gaming state, and the control is performed for a predetermined period of time. The Compared to the normal gaming state, the time-short state is a variation display time of each of the special symbol display 8, the variation display device 9, and the normal symbol display 10 (the time from the start of variation to the time when the display result is derived and displayed). ) Is a control state in which display results are derived and displayed at an early stage. Furthermore, during the time-shortening state, the probability that the stop symbol in the normal symbol display 10 becomes a winning symbol is increased, the opening time of the movable pieces 13 and 13 of the start winning device 15 is lengthened, and the number of times of opening is increased. . In the short-time state, the display time of the fluctuation of the symbol is shortened, so that the number of reserved memories to be described later is exhausted early, and the start winnings that have occurred exceeding the upper limit (for example, “4”) of the number of reserved memories are invalidated. Since it is easy to derive and display the jackpot display result early in the short term, it is easy to derive and display the jackpot display result early, so the display result of the variable display is likely to become the display result of the jackpot symbol from a time efficient viewpoint It becomes a gaming state advantageous to the player. As described above, in the case of a probable big hit, the high probability state and the short time state are controlled in a predetermined period after the end of the big hit gaming state. The short time state over a predetermined period after the end of the jackpot gaming state is the earlier, until the next jackpot gaming state occurs or until the special symbols and decorative symbols are displayed a predetermined number of times (100 times). Continue until either condition is met.

  Also, when considering the payout of pachinko balls according to the winning, the time-short state is shorter than the non-time-short state and the normal symbol variation display time is shortened, and the stop symbol in the normal symbol display 10 becomes a winning symbol. The probability is increased, the opening time of the movable pieces 13 and 13 of the start winning device 15 at the time of winning is lengthened, and the number of times of opening the movable pieces 13 and 13 of the starting winning device 15 at the time of hitting is increased. Based on this, the movable pieces 13 and 13 of the start winning device 15 are likely to be in an open state as compared with the normal gaming state. Accordingly, in the short-time state, it is easy to generate a prize (including both a case where the start prize is valid and a case where the prize is invalid) in the second start port 15b, so the number of pachinko balls ( The ratio of the number of pachinko balls (the number of balls to be paid out) to be paid out as winning balls according to the winning is greater than the number of hitting balls) as compared to the normal gaming state. In general, the ratio of the number of paid-out balls for winning a prize to the number of shot balls is called “base”. For example, when there are 40 payout balls with respect to 100 shot balls, the base is 40 (%). In the case of this embodiment, for example, a time-short state having a higher base than a non-time-short state such as a normal gaming state is called a high base state, and conversely, a normal gaming state having a lower base compared to such a high base state Such a non-time-short state is called a low base state.

  Thus, the ratio of the number of award balls paid out by winning a prize to the number of balls launched is generally called “base”, but the maximum number of pachinko balls fired per unit time such as 1 minute is limited to a certain number. ing. For this reason, the “base” can also be indicated by a total value of the number of winning balls paid out by winning a plurality of winning openings provided in the game area in a unit time. For example, assuming that the maximum number of pachinko balls fired per unit time is 100, the total number of award balls paid out by winning in a unit time matches the general “base” value. Based on such relevance, in the present embodiment, the first starting port 15a, the second starting port 15b, the first normal winning port 29, the second normal winning port 30, the third normal winning port 33, and the first Each of the four normal winning openings 39 is set as an abnormality monitoring target winning opening, and the total value of the number of paid-out balls by winning the abnormal monitoring target winning opening is called a base and is used as an abnormality monitoring target related to winning. .

  Whether the probability variation state (high probability state) or the non-probability variation state (low probability state) is determined based on whether or not the probability variation flag, which is a flag set in the probability variation state, is set. . Whether the time-short state (high base state) or the non-time-short state (low base state) is determined is based on whether or not the time-short flag, which is a flag set in the time-short state, is set. Is done.

  In addition, in the state that is not controlled to the above-mentioned time-short state, every time the number of special symbols on-hold storage exceeds a predetermined number, the memory that controls the memory variation shortened state that shortens the variation display time of the special symbol and the decorative symbol Variation shortening control is performed. The memory fluctuation shortening control ends when the number of reserved symbols for special symbols is less than a predetermined number. Therefore, even in a state where the time-short state is not controlled, there is a case where the variation display time of the special symbol and the decorative symbol is shortened.

  The decorative symbols that are variably displayed in the variable display device 9 are variably displayed in a predetermined relationship with the special symbol variation display in order to enhance the decoration effect of the special symbol variation display in the special symbol display 8. It is a symbol with a special meaning. For example, the predetermined relationship with respect to the symbol includes, for example, the relationship in which the variation display of the decorative symbol starts when the variation display of the special symbol is started, and the display result of the special symbol at the end of the variation display of the special symbol. This includes a relationship in which the decorative symbol display result is derived and displayed and the decorative symbol variation display is terminated. When the special symbol display unit 8 derives and displays a predetermined jackpot symbol as a display result, the variable display device 9 derives and displays a combination of the jackpot symbol having left, middle and right symbols as a display result. The Such a display result of the jackpot symbol by the special symbol and the display result of the combination of the jackpot symbol by the decoration symbol are referred to as a jackpot display result.

  Since the special symbol display 8 and the fluctuation display device 9 have the correspondence relationship as described above, the fluctuation display results may be collectively referred to as a fluctuation display unit in the following description.

  In the normal game state, the effective display line on which the variable display result of the decorative symbols is stopped and displayed on the variable display device 9 is, for example, only in the upper stage of each of the “left”, “middle”, and “right” variable display units. , A horizontal direction consisting of only the middle stage, only the lower stage, an oblique direction consisting of the upper stage in the “left” variable display section, the middle stage in the “middle” variable display section, and the lower stage in the “right” variable display section, or “ It is determined in an oblique direction including a lower stage in the “left” variable display section, a middle stage in the “middle” variable display section, and an upper stage in the “right” variable display section. On the other hand, during probability change, which is a probability change game state, the active line stops one decorative symbol at each of the “left”, “middle”, and “right” variable display portions as shown in FIG. By displaying, only one is defined in the horizontal direction. At this time, the decorative symbols on the “left”, “middle”, and “right” variable display portions are displayed larger than in the normal gaming state.

  Next, the reach display mode (reach) will be described. The reach display mode (reach) in the present embodiment means that the symbols that have not been stopped when the stopped symbols constitute a part of the jackpot symbol, and that all or This is a state where some symbols are synchronously displayed while constituting all or part of the jackpot symbol.

  For example, in the variable display device 9, an effective line (one effective line in the case of the present embodiment) that becomes a big hit when the symbol stops is determined in advance, and a part of the display area on the effective line is displayed. A state in which the variable display is performed in the display area on the active line that has not been stopped when the predetermined symbol is stopped (for example, the left, middle, and right variable display areas in the variable display device 9). Of these, all or some of the display area on the active line) Are in a variable display in synchronism while constituting all or part of the jackpot symbol (for example, the variable display is performed in all of the left, middle and right display areas in the variable display device 9, Same state) the variation displayed with the symbol are aligned is made that reach the display mode or reach.

  Also, during the reach, an unusual effect may be performed with LEDs or sounds. This production is called reach production. Further, in the case of reach, a character (an effect display imitating a person or the like, which is different from a design (decoration design etc.)) or a display mode (for example, color etc.) of the background image of the variable display device 9 is displayed. ) May change. This change in character display and background display mode is called reach effect display. In addition, some reach is set so that when it appears, a big hit is likely to occur compared to a normal reach. Such special (specific) reach is called super reach.

  In addition, with respect to the variable display device 9, there is a case where a big hit notice is given as a notice effect for notifying that a big hit has occurred in the variable display that triggers the occurrence of the big hit.

  In the case of this embodiment, as a big hit, a plurality of types of big hits such as a normal big hit and a probable big hit are provided. In the following description, when “big hit” is simply indicated without specifying the types of big hits, it is a case where these multiple types of big hits are representatively shown.

  Usually, the big hit is a big hit (non-probable big hit) that becomes a low probability state and a low base state by not being in a probable change state after the end of the big hit gaming state and being in a short time state. Such a state with a low probability state and a low base state is called a low probability low base state. The probable big hit is a big hit that becomes a probable state after the end of the big hit gaming state, a high probability state in which the time is short for a predetermined period, and a high base state. Such a state with a high probability state and a high base state is referred to as a highly accurate high base state. After the probability variation big hit, when the predetermined period elapses, the time reduction state ends, and the state becomes a high probability state and a low base state. Such a state having a high probability state and a low base state is referred to as a high probability low base state.

  In addition, with respect to the variable display device 9, there is a case where a big hit notice is given as a notice effect for notifying that a big hit has occurred in the variable display that triggers the occurrence of the big hit.

  The game control microcomputer 156 includes a ROM 54 for storing a game control (game progress control) program and the like, a RAM 55 as storage means (variation data storage means for storing fluctuation data) used as a work memory, and a program. Therefore, it includes a CPU 56 that is a processor that performs a control operation, and an I / O port 57. The game control microcomputer 156 is a one-chip microcomputer. Note that the one-chip microcomputer may include at least the RAM 55 in addition to the CPU 56. Further, the ROM 54 and the I / O port 57 may be externally attached or incorporated.

  In the game control microcomputer 156, the CPU 56 executes control according to a program stored in the ROM 54. Therefore, the execution (or processing) of the game control microcomputer 156 as described below specifically means that the CPU 56 executes control according to a program. The same applies to microcomputers mounted on substrates other than the main substrate 31. The game control means is realized by a game control microcomputer 156 including a CPU 56.

  The game control microcomputer 156 includes a clock circuit that generates a clock signal, a reset controller that functions as a system reset means, a random number circuit, and a CTC that sends an interrupt request signal to the CPU 56.

  The random number circuit is a hardware circuit that is used to generate a random number for determination to determine whether or not to win a jackpot based on the display result of the variation display of the special symbol and the decorative symbol. This random number circuit updates numerical data in accordance with a set update rule within a numerical range in which an initial value (for example, 0) and an upper limit value (for example, 65535) are set, and at random timing. Based on the fact that the start winning time generated is the time of reading (extracting) the numerical data, it has a random number generation function in which the numerical data to be read becomes a random value.

  The game control microcomputer 156 reads the numerical data from the random number circuit as the random number value R1 when a start winning to the first starting port switch 14a or the second starting port switch 14b occurs, and specifies a specific value based on the numerical data. It is determined whether or not to make a jackpot display result as a display result, that is, whether or not to make a jackpot. When it is determined that the game is a big hit, the gaming state is shifted to a big hit gaming state as a specific gaming state advantageous to the player. Whether the random number generated by the random number circuit is a big hit, such as a random number for probability variation determination for determining whether or not to make a probability variation, and a random number for variation pattern determination for determining a variation pattern of a special symbol. It may be used as a random number for determination other than determination.

  The random number circuit includes a numeric data update range selection setting function (initial value selection setting function and upper limit selection setting function), numeric data update rule selection setting function, and numeric data update rule. It has various functions such as a selection switching function. With such a function, the random number circuit can improve the randomness of the generated random number.

  Further, the game control microcomputer 156 has a function of setting an initial value of the numerical data updated by the random number circuit. For example, the game control microcomputer 156 stores the game control microcomputer 156 stored in a predetermined storage area such as the ROM 54. Numerical data obtained by performing a predetermined calculation using an ID number (ID number assigned with a different numerical value for each product of the game control microcomputer 156) is used as an initial value of the numerical data updated by the random number circuit. Set. Thereby, the randomness of the random number generated by the random number circuit can be further improved. Further, when setting the initial value, by performing a predetermined calculation using the ID number, it is possible to make it difficult to recognize the initial value of the random number only by looking at the ID number of the game control microcomputer 156. Therefore, it is possible to more reliably prevent the transition condition to the big hit state from being illegally established by an action such as generating a capture signal using a radio signal to the pachinko gaming machine 1. Can be improved.

  The clock circuit outputs a system clock signal to the CPU 56, and outputs a reference clock signal CLK having a predetermined cycle generated by dividing the system clock signal to the power of 2 (= 128) to each random number circuit. When a low level signal is input for a certain period, the reset controller outputs a predetermined initialization signal to the CPU 56 and each random number circuit to reset the game control microcomputer 156 as a system.

  In addition, the game control microcomputer 156 is equipped with two random number circuits having different ranges of random number values that can be generated.

  The projecting ball contact surface 313 is formed in a flat shape from the support portion 311 toward the upper end (tip), and particularly from the front side toward the front surface 6a of the game board 6 as shown in FIG. In accordance with the return ball abutment surface 314 side, that is, incline toward the front surface 6 a side of the game board 6, and abuts on the launch ball moving from the hitting ball guide passage 45 toward the game area 7. At this time, the fired ball is guided toward the front surface 6a side of the game board 6, so that the fired ball is prevented from contacting the front glass plate 102a away from the front surface 6a.

  This is because, as shown in FIG. 12B, the separation width L3 between the front surface 6a of the game board 6 and the inner surface of the glass plate 102a of the glass door frame 102 may cause clogging of a ball or the like. As the size of the pachinko ball is larger than the diameter L2 of the pachinko ball, the pachinko ball launched from the hitting ball launching device is caused by factors such as the launching status of the hitting ball launching device and the inclination of the game board 6. This is because it moves back and forth between the front surface 6a and the inner surface of the glass plate 102a (see FIG. 12B), and this causes variations in the flying of the pachinko balls.

  Specifically, as shown in FIG. 10A, the launch ball contact surface 313 is front and rear with respect to the orthogonal surface T orthogonal to the front surface 6a of the game board 6, that is, the return ball contact surface 314. The side is arranged so as to be inclined at a predetermined angle (inclination angle Θ1≈5 ° in this embodiment).

  In addition, in order to examine the appropriate range of the inclination angle Θ1 of the projecting ball contact surface 313 with respect to the orthogonal surface T, the present applicant conducted the following test.

As a test method, the ball return prevention device 300 of the present invention is installed in the actual pachinko machine 1 and the pachinko ball is continuously fired all day long. The method to confirm was adopted. Then, this test is performed when the inclination angle Θ1 = 0 °, the inclination angle Θ1 = 5 °, the inclination angle Θ1 = 10 °, the inclination angle Θ1 = 15 °, and the inclination angle Θ1 = 0. Based on the ball flight stability in the case of °, when the inclination angle Θ1 = 5 °, the inclination angle Θ = 10 °, and the inclination angle Θ = 15 °, the ball flight stability was compared. The results as shown in 1 were obtained.

  When the tilt angle Θ1 = 0 °, as described above, the launch ball is in front of the game board 6 due to various factors such as the launch situation of the pachinko ball by the hitting ball launcher and the installation situation of the pachinko machine 1 (tilt tilt). For example, the ball jump may vary due to contact with the glass plate 102a of the glass door frame 102 away from 6a.

  On the other hand, when the tilt angle Θ1 = 5 ° and the tilt angle Θ1 = 10 °, the launch ball is guided to the front surface 6a side of the game board 6 by the contact with the launch ball contact surface 313 as described above. Therefore, as shown in Table 1, as compared with the case of the inclination angle Θ1 = 0 °, the variation of the ball skip was suppressed well.

  In the case of the inclination angle Θ1 = 15 °, the path of the launch ball is suddenly changed by the contact with the launch ball contact surface 313, and the pachinko ball is strongly pressed against the front surface 6a, and the reaction force greatly rebounds the glass. In order to easily collide with the plate 102a, it was confirmed that the ball jump variation was almost the same as in the case of the inclination angle Θ1 = 0 °.

  As can be seen from the test results, the inclination angle Θ1 is preferably greater than 0 ° and not more than 10 ° (0 ° <Θ1 ≦ 10 °), and more preferably 5 ° to 10 ° (5 ° ≦ Θ1 ≦). 10) is more preferable. In this way, the pachinko ball can be guided toward the surface 6a side of the game board 6 without being excessively pressed against the surface 6a of the game board 6.

  In addition, the firing ball contact surface 313 in the present embodiment gradually increases the thickness (thickness) of the opening / closing portion 310 of the opening / closing member 301 as the distance from the front surface 6a side of the game board 6 increases. Since the board 6 is inclined toward the front surface 6 a, the launch ball contact surface 313 is inclined toward the front surface 6 a side of the game board 6 without affecting the return ball contact surface 314 on the opposite side. Can be provided.

  The return ball abutment surface 314 includes a first abutment surface 314a and a second abutment surface 314b that are vertically partitioned with a bent side 314c extending in the front-rear direction at an upper portion thereof. Yes. The first contact surface 314a is formed in a flat shape from the support portion 311 toward the upper end (tip), and is particularly perpendicular to the front surface 6a of the game board 6 as shown in FIG. Is arranged. Further, as shown in FIG. 9B in particular, the second contact surface 314b is fired from the bent side 314c, that is, from the upper end of the first contact surface 314a toward the upper end (tip) of the opening / closing part 310. It is a strip-like inclined surface formed on the tip side of the first abutting surface 314a so as to incline toward the ball abutting surface 313, and is formed flat in the front-rear direction.

  That is, the second contact surface 314b is an inclined surface that is inclined at a predetermined angle Θ2 (Θ2≈26 ° in the present embodiment) with respect to the first contact surface 314a. It functions as a guide surface that guides the pachinko ball that has entered between 43 and the upper end of the opening / closing part 310 toward the game area 7 (see FIG. 11B).

  Further, between the firing ball contact surface 313 and the second contact surface 314b at the upper end of the opening / closing part 310, the plane is perpendicular to the launch ball contact surface 313 and the first contact surface 314a and is flat. An upper end surface 315 having a substantially triangular shape that is gradually tapered toward the front surface 6a of the game board 6 is formed.

  A support portion 311 and a weight portion 312 are connected to the lower end of the opening / closing portion 310 thus configured. The support portion 311 is formed in a substantially cylindrical shape, and a through hole 316 through which a swing shaft 317 for pivotally supporting the opening / closing member 301 with respect to the mounting support portion 302 is inserted is provided in the front and rear. It is formed to penetrate in the direction. The swing shaft 317 is formed of a stepped pin, and is attached to the attachment support portion 302 by press-fitting a small diameter portion at the tip into a fitting hole 338 described later.

  A weight part 312 for biasing the opening / closing part 310 toward the closed position for closing the connecting part 46 extends from the support part 311 toward the opposite side of the opening / closing part 310, and the weight part 312. Is formed with a bottomed insertion hole 319 into which a metal weight bar 318 having a heavier specific gravity than the synthetic resin material constituting the weight portion 312 can be inserted, and the weight bar 318 is inserted into the insertion hole 319. The urging force with respect to the opening / closing part 310 can be increased without increasing the size of the weight part 312.

  In the opening / closing member 301 configured as described above, the opening / closing part 310 and the weight part 312 are extended toward the opposite sides with the support part 311 as the center. Further, a notch recess 320 for accommodating a boss 321 described later is formed on the rear side of the support portion 311, that is, on the attachment support portion 302 side. That is, the opening / closing part 310 and the weight part 312 are formed longer than the front-rear width of the support part 311.

  The opening / closing part 310 is formed in a plate shape having a substantially wedge-shaped cross section as described above, the return ball contact surface 314a is parallel to the central axis of the swing shaft 317 in the front-rear direction, and the swing shaft It extends from the support portion 311 so as to be disposed at a position shifted to the left side (the hitting ball guiding passage 45 side) from the central axis of 317. That is, the opening / closing part 310 is connected to the support part 311 via the bent part 310a.

  Next, the attachment support part 302 will be described. The attachment support portion 302 mainly includes a base portion 330 attached to the front surface 6 a of the game board 6 and a wall portion 331 protruding forward from the front surface of the base portion 330. The base portion 330 is formed of a plate-like member that is formed in a substantially arc shape when viewed from the front along the hitting ball guide passage 45, and the attachment support portions 302 are attached to the front surface 6 a of the game board 6 at both ends in the longitudinal direction. A mounting hole 333 of the mounting screw 332 (see FIG. 7) is formed, and a positioning convex portion 334 that can be fitted in a positioning hole (not shown) formed in the front surface 6a of the game board 6 on the back side. 334 (see FIG. 9) protrudes backward.

  As shown in FIGS. 8 and 9, the wall portion 331 opens the side surface of the supporting portion 311 and the weight portion 312 on the hitting ball guide passage 45 side in the opening / closing member 301 in a substantially vertical position, and the side of the game area 7 The pachinko ball that has entered the game area 7 does not collide with the support part 311 or the weight part 312 and does not hinder the opening and closing of the opening / closing part 310. It is like that.

  A cylindrical boss portion 339 is provided in the wall portion 331 so as to project forward from the front surface of the base portion 330. The front end surface of the boss portion 339 is formed with a fitting hole 338 into which the above-described rocking shaft 317 is fitted. By inserting (press-fitting) the tip of the rocking shaft 317 into the fitting hole 338, the base portion is formed. The opening / closing member 301 is pivotally supported with respect to 330.

  In this embodiment, the rocking shaft 317 is attached to the base 330 by fitting (press-fitting) the tip of the rocking shaft 317 into the fitting hole 338, but a screw is attached to the tip of the rocking shaft 317. May be attached by forming a portion and screwing the screw portion into the front end surface of the boss portion 339.

  Further, in this embodiment, the opening / closing member 301 can be swung freely with respect to the base portion 330 by inserting the tip of the swing shaft 317 inserted through the through hole 316 of the opening / closing member 301 into the fitting hole 338 of the boss portion 339. For example, a positioning convex portion that can be fitted to a fitted portion provided on a side portion of the opening / closing member 301 is provided on the front end surface of the boss portion 339 so as to project the positioning convex portion. In a state where the support portion of the opening / closing member 301 with respect to the base portion 330 is determined by fitting the portion to the fitting portion, the swing shaft 317 is inserted into the through hole 316 so that the tip can be inserted into the insertion hole 338. Well, this makes it easy to attach the opening / closing member 301 to the base 330.

  Further, on the inner surface of the wall portion 331, a rotation restricting protrusion 337 that protrudes inwardly extends in the front-rear direction, and the rotation restricting protrusion 337 abuts against the side surface of the weight portion 312. The rotation of the weight portion 312 is restricted.

  Specifically, the opening / closing member 301 that is swingably supported by the swing shaft 317 is held in a substantially vertical posture in a balanced state by the weight of the weight portion 312. The strip 337 is provided so as to come into contact with the side surface of the weight portion 312 balanced by the weight of the weight portion 312 in a slightly pressed state. That is, since the side surface of the weight portion 312 is always held in contact with the rotation restricting protrusion 337, the opening / closing portion 310 is always securely in the closed position (the solid line position in FIG. 11A) where the connecting portion 46 is closed. Is supposed to be retained.

  The upper end 331 a of the wall portion 331 is in contact with a bent portion 310 a provided at the lower portion of the opening / closing portion 310. That is, the opening / closing member 301 is swingable between a maximum open position where the bent portion 310 a contacts the upper end 331 a of the wall portion 331 and a closed position where the rotation restricting protrusion 337 contacts the side surface of the weight portion 312. It is supported.

  An inner rail holding portion 336 having a fitting groove 335 into which the front end portion of the inner rail 42 can be fitted is provided at the lower end portion of the wall portion 331. Since the fitting groove 335 is formed with a predetermined length in the extending direction of the hitting ball guide passage 45, the fitting support portion 302 for the inner rail 42 is fitted by fitting the inner rail 42 into the fitting groove 335. Can be easily determined.

  Further, as shown in FIG. 11, the end portion of the inner rail 42 fitted in the fitting groove 335 extends to the vicinity of the bent portion 310 a of the opening / closing portion 310 to cover the open portion of the wall portion 331. ing. That is, both side surfaces near the end of the inner rail 42 are arranged so that one faces the hitting ball guide passage 45 and the other faces the weight portion 312. In other words, the end portion of the inner rail 42 is disposed so as to partition the hitting ball guide passage 45 and the weight portion 312 accommodated in the space surrounded by the wall portion 331, so that the wall portion is separated from the hitting ball guide passage 45. Pachinko balls are prevented from entering the space surrounded by 331.

  As described above, the mounting support portion 302 is integrally provided with the inner rail holding portion 336 that holds the front end portion of the inner rail 42, that is, the end portion opposite to the front surface 6 a of the game board 6 from one side. Therefore, it is possible to easily determine the mounting position of the mounting support portion 302 with respect to the inner rail 42, and thus the opening / closing member 301, simply by fitting the front end portion of the inner rail 336 into the fitting groove 335.

  Further, contact of the pachinko ball moving in the hitting ball guiding passage 45 with the weight portion 312 can be easily prevented only by using the inner rail 42 without newly forming a prevention piece or the like on the base portion 330.

  Next, the use situation of the ball return prevention device 300 configured as described above will be described with reference to FIGS. 11 and 12.

  As shown in FIG. 11, the ball return prevention device 300 has an inner side of the connecting portion 36 so that the connecting portion 46 is opened and closed by the opening and closing portion 310 in a state where the inner rail 42 is held by the inner rail holding portion 336. Arranged in the section. Thus, in a state where the attachment support portion 302 is attached to the front surface 6 a of the game board 6 along the inside of the inner rail 42 by the attachment screw 332, the lower half portion of the attachment support portion 302 is the inner surface of the inner rail 42. 42a is opposed to 42a.

  The opening / closing member 301 supported so as to be swingable with respect to the attachment support portion 302 via the swing shaft 317 includes a closed position where the opening / closing portion 310 protrudes toward the connecting portion 46 and closes the connecting portion 46, and the connecting portion. It is supported so as to be swingable between an open position where the connection portion 46 is opened by retracting from the link 46. As shown by the solid line in FIG. 11A, the opening / closing part 310 is always held in the closed position by the weight of the weight part 312 described above.

  As shown in FIG. 12 (a), the opening / closing part 310 does not completely close the connecting part 46 in the closed position, but in the state where it is held in the closed position, that is, the direction of travel of the pachinko ball, that is, the hit ball The guide passage 45 is disposed in a state inclined by about 45 ° with respect to the longitudinal direction of the guide passage 45, and the separation width L1 between the upper end of the opening / closing part 310 and the inner side surface of the outer rail 43 is at least smaller than the diameter L2 of the pachinko ball P The connecting part 46 is closed to such an extent that it becomes a dimension (L1 <L2). That is, closing the connecting portion 46 means that the pachinko ball cannot return from the game area 7 into the hitting guide passage 45, and the opening / closing portion 310 does not completely close the connecting portion 46 in the closed position. May be.

  In addition, the opening / closing part 310 has a substantially vertical posture in which the upper end thereof is slightly inclined toward the game area 7 on the right side in the closed position, and the inner rail 42 in the open position (see the two-dot chain line position in FIG. 11A). The projecting ball contact surface 313 is opposed to the inner surface of the outer rail 43.

  The pachinko ball P launched by the hitting ball launcher enters the hitting ball guide passage 45 by the hitting ball guide rail 117, and then moves toward the upper game area 7 along the inner side surface of the outer rail 43 in the hit ball guide passage 45. Moving. Then, when it reaches the connecting portion 46, it collides with the launching ball contact surface 313 of the opening / closing portion 310, pushes the opening / closing portion 310 to forcibly open the opening / closing portion 310, and moves along the inner surface of the outer rail 43 as it is. Then, the game area 7 is entered.

  The opening / closing part 310 that is forcibly swung to the open position by the pachinko ball P swings in the reverse direction by the weight of the weight part 312 after the pachinko ball P has passed, and before the subsequent pachinko ball P arrives. Return to the closed position.

  Then, as shown in FIG. 11B, among the pachinko balls that forcibly opened the opening / closing part 310 and pushed the opening / closing part 310 into the game area 7, The pachinko ball that falls substantially vertically downward and returns back toward the hitting ball guide passage 45 located on the lower side is placed on the return ball contact surface 314 formed on the game area 7 side in the opening / closing part 310 that has returned to the closed position. By coming into contact, the return to the hitting ball guide passage 45 is prevented. The pachinko ball that has returned without opening the opening / closing part 310 completely, that is, without entering the game area 7, flows back down in the hitting ball guide passage 45 and passes through the foul ball guide passage 118 described above. And collected in a surplus ball passage (not shown).

  In addition, after entering the game area 7, the pachinko balls that have returned to the hitting ball guide passage 45 without any momentum return and swing from the open position to the closed position, and the inner surface of the outer rail 43. 12A and 12B, the second contact formed on the upper end side of the return ball contact surface 314 without contacting the upper end surface 315, as shown in FIGS. By contacting the surface 314b (refer to the contact point X in FIG. 12B), it is guided toward the game area 7, so that the opening / closing part 310 that swings back and forth has its upper end surface 315 and the outer rail 43 It is prevented that the pachinko sphere is bitten with the inner side surface.

  Also, as shown in FIG. 12B, the pachinko ball P is guided to the front surface 6a side of the game board 6 by the contact with the launch ball contact surface 313, so that the return ball and the second ball The contact point X in the front-rear width direction with the contact surface 314b is often slightly closer to the game board 6 side than the center position in the front-rear width direction. At the position near the game board 6, the left and right widths of the upper end surface 315 having a substantially triangular shape in plan view are formed narrower than the front side, so that the pachinko ball P is difficult to ride on the upper end surface 315, In addition, since the second contact surface 314 b is easily guided to the game area 7 side, the pachinko ball P is hardly sandwiched between the inner surface of the outer rail 43.

  As described above, in the ball return prevention device 300 according to the embodiment of the present invention, the pachinko ball P launched from the game ball launching device and guided toward the game area 7 by the hitting ball guide passage 45 is as follows. By abutting on the launch ball abutting surface 313 of the opening / closing part 310 of the opening / closing member 301, the opening / closing part 310 is opened to enter the game area 7, and after entering the game area 7, the opening / closing part 310 is opened. Since the connecting portion 46 is closed, the pachinko ball that has entered the game area 7 is prevented from returning to the hitting guide passage 45.

  Further, since the launch ball contact surface 313 is inclined toward the surface 6a side of the game board 6, not only the pachinko ball is guided toward the surface 6a side of the game board 6, but also the return ball contact surface 314 Since the second contact surface 314b is formed at the distal end portion, the return ball enters between the distal end of the opening / closing portion 310 and the inner side surface of the outer rail 43 when the opening / closing portion 310 returns to the closed position. In this case, since the return ball is guided to the game area 7 side by the second contact surface 314b, it is difficult to be caught between the tip of the opening / closing part 310 and the outer rail 43, so that the pachinko ball to the game area 7 The launch is stable.

  In addition, the launch ball contact surface 313 is configured by gradually increasing the thickness of the opening / closing portion 310 from the surface 6a side of the game board 6 so that the return ball contact on the opposite side is formed. Without affecting the surface 314, the ball contact surface 313 can be provided to be inclined toward the surface 6a of the game board 6.

  The inner rail 42 is made of a thin strip metal material, the opening / closing member 301 and the mounting support 302 of the ball return prevention device 300 are made of a synthetic resin material containing carbon fiber, and the swing shaft 317 is a metal rod. That is, since the ball return prevention device 300 is made of a conductive member, the charge charged to the pachinko ball is brought into contact with the opening / closing portion 310 from the opening / closing member 301 via the swing shaft 317. 302 is conducted. Therefore, since the electric charge accumulated in the opening / closing member 301 can be released to the inner rail 42, the static electricity charged in the pachinko ball contacting the opening / closing portion 310 can be removed before entering the game area 7, It is possible to prevent the charge from adversely affecting the flow of the pachinko ball in the game area 7.

  In this embodiment, the opening / closing member 301 and the mounting support portion 302 are made of a synthetic resin material containing carbon fiber, so that the entire opening / closing member 301 and the mounting support portion 302 have conductivity. For example, a conductive member such as a metal piece is embedded in the launch ball contact surface 313 or the return ball contact surface 314 that can contact a pachinko ball so that the conductive member is exposed, and the conductive member is connected to the inner rail 42 by a ground wire or the like. You may make it do.

  Next, based on FIGS. 13 to 15, a ball return preventing device 300 'according to a second embodiment of the present invention will be described. FIG. 13 is a front view and a rear view showing the ball return prevention device as the second embodiment. FIG. 14 is a left side view, a right side view, a plan view, and a bottom view showing the ball return prevention device. 15A is a cross-sectional view taken along the line AA in FIG. 13, and FIG. 15B is a cross-sectional view taken along the line BB in FIG. In the second embodiment, the same components as those in the ball return prevention device 300 of the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  In the ball return prevention device 300 ′ of the second embodiment, the point that the shape of the mounting support portion 302 is different and the point that the mounting hole 333 is formed only in one place are the ball return prevention of the first embodiment. Different from the device 300. Specifically, the mounting support portion 302 of the ball return prevention device 300 according to the first embodiment has a wall portion 331 projecting from a part of the front surface of the plate-like base portion 330, but the mounting support portion according to the second embodiment. As for the part 302, the base 330 and the wall part 331 are formed substantially integrally, and only the attaching part to which the opening-and-closing member 301 is attached is formed in concave shape. In addition, since the two positioning convex portions 334 and 334 are projected, even one mounting screw 332 can be attached to the front surface 6 a of the game board 6.

  As described above, the shape of the attachment support portion 302 that supports the opening / closing member 301 in a swingable manner can be arbitrarily changed. When used by attaching to the front surface 6a of the game board 6, the ball return prevention device 300 according to the first embodiment is used. Has the same action and effect as.

  Next, based on FIGS. 16-19, the ball | bowl return prevention apparatus 300 '' as Example 3 of this invention is demonstrated. FIG. 16 is a front view and a rear view showing the ball return preventing device as the third embodiment. FIG. 17 is a left side view, a right side view, a plan view, and a bottom view showing the ball return preventing device. 18A is a cross-sectional view taken along line AA in FIG. 16, and FIG. 18B is a cross-sectional view taken along line BB in FIG. FIG. 19A is a partially enlarged view of the upper end of the opening / closing part, and FIG. 19B is a plan view of FIG. In the third embodiment, the same components as those in the ball return prevention device 300 of the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  In the ball return prevention device 300 ″ of the third embodiment, the shape and arrangement of the opening / closing member 301 are different from those of the ball return prevention device 300 of the first embodiment. Specifically, the opening / closing member 301 of the third embodiment is arranged so as to be inclined toward the front surface 6a side of the game board 6 with respect to the orthogonal plane T without changing the plate thickness of the opening / closing member 301. Thus, the launch ball contact surface 313 can be provided to be inclined toward the front surface 6 a side of the game board 6.

  In the first and second embodiments, the second contact surface 314b is formed at the tip of the return ball contact surface 314. In the third embodiment, the second contact surface 314b is formed at the tip of the firing ball contact surface 313. Two contact surfaces 313b are formed. Specifically, as shown in FIG. 18A, the launch ball contact surface 313 has a predetermined angle (in this embodiment) with respect to an orthogonal plane T orthogonal to the front surface 6a of the game board 6. (Tilt angle Θ3≈10 °). As described above, the inclination angle Θ3 is preferably greater than 0 ° and not more than 10 ° (0 ° <Θ3 ≦ 10 °), and more preferably not less than 5 ° and not more than 10 ° (5 ° ≦ Θ3 ≦ 10). It is more preferable. In this way, the pachinko ball can be guided without being strongly pressed against the surface 6a of the game board 6.

  Further, the projecting ball contact surface 313 includes a first contact surface 313a and a second contact surface 313b that are vertically divided with a bent side 314c extending in the front-rear direction at an upper portion thereof. Has been. In particular, as shown in FIG. 18B, the first contact surface 313a is formed flat from the support portion 311 side toward the upper end (tip), and the second contact surface 314b has a bent side. 314c, that is, a belt-like inclined surface that inclines toward the return ball contact surface 314 on the opposite side from the upper end of the first contact surface 313a toward the upper end (tip) of the opening / closing part 310, and is flat in the front-rear direction. It is formed in a shape.

  That is, the second contact surface 313b is an inclined surface that is inclined at a predetermined angle Θ4 (Θ4≈45 ° in the present embodiment) with respect to the first contact surface 313a. It functions as a guide surface for stably guiding pachinko balls moving from 45 toward the game area 7 (see FIG. 19).

  In addition, the opening / closing part 310 of the third embodiment is disposed so as to be inclined about a predetermined angle with respect to the orthogonal plane T (axial center of the swinging shaft 317) without changing the plate thickness of the opening / closing member 301. The launching ball contact surface 313 faces the front surface 6a side of the game board 6, and the return ball contact surface 314 disposed on the opposite side is also arranged so as to be substantially parallel to the firing ball contact surface 313. ing. Therefore, the second contact surface 313b and the return ball contact surface 314 at the upper end of the opening / closing part 310 are orthogonal to the first contact surface 313a and the return ball contact surface 314, and are viewed in plan view. Thus, an elongated strip-shaped upper end surface 315 (see a plan view of FIG. 17) having a substantially parallelogram shape is formed.

  In the ball return prevention device 300 ″ of the third embodiment configured as described above, the pachinko ball that has returned to the hitting ball guide passage 45 side after entering the game area 7 is moved from the open position to the closed position. When entering between the upper end of the opening / closing portion 310 that swings back and forth and the inner surface of the outer rail 43, as shown in FIG. Since the return ball abutment surface 314 is guided toward the game area 7, the return swinging opening / closing section 310 bites the pachinko ball between the upper end surface 315 and the inner surface of the outer rail 43. Is prevented.

  Further, since the second contact surface 313b is formed on the firing ball contact surface 313 side, as shown in FIG. 19A, the second contact surface 313b has moved from the hitting ball guide passage 45 toward the game area 7. When the pachinko ball collides with the launching ball contact surface 313 and pushes the opening / closing part 310 to forcibly open the opening / closing part 310, the second contact surface 313b is positioned along the moving direction of the pachinko ball. Thus, the pachinko sphere functions as a guide surface for smoothly guiding the pachinko sphere in the moving direction, so that it is possible to stabilize the flying of the pachinko sphere. Further, the pachinko ball is guided toward the inner surface of the outer rail 43 by the return force acting to return the opening / closing part 310 to the closed position by the weight part 312 on the opening / closing part 310 that is forcibly opened. Therefore, the pachinko ball comes to move stably along the outer rail 43.

  Although the embodiments of the present invention have been described with reference to the drawings, the present invention is not limited to these embodiments, and modifications and additions within the scope of the present invention are included in the present invention. Needless to say.

  For example, in the above-described embodiment, the opening / closing part 310 is swung back from the open position to the closed position using the gravity of the weight part 312 and the weight bar 318, but the opening / closing part 310 is moved toward the closed position. The return force applying means for applying the return force is not limited to a weight member or the like, and may be, for example, a coil spring or a leaf spring.

  In the above-described embodiment, the return ball contact surface 314 is arranged in a state parallel to the orthogonal surface T orthogonal to the front surface 6a which is a game surface or inclined toward the firing ball contact surface 313. However, it may be provided so as to incline toward the front surface 6a of the game board 6. By doing so, the return ball is directed toward the front surface 6a side of the game board by the return ball contact surface 314. Since it can be guided, the return ball can flow down along the front surface 6a of the game board.

  In the above-described embodiment, the launch ball contact surface 313 and the return ball contact surface 314 are flat surfaces. However, for example, the launch ball contact surface 313 and the return ball contact surface 314 are formed in curved surfaces that are gently curved in the inclination direction. Also good.

  In the first and second embodiments, the return ball contact surface 314 is divided into the first contact surface 314a and the second contact surface 314b with the bent side 314c as a boundary. The launching ball contact surface 313 was partitioned into the first contact surface 313a and the second contact surface 313b with the bent side 313b as a boundary, but without forming such a bent side, The second contact surfaces 314b and 313b may be provided continuously from the top of the first contact surface 314a or the first contact surface 313a.

  In the embodiment, the upper end surface 315 of the flat surface facing the direction orthogonal to the return ball contact surface 314 is formed at the upper end of the opening / closing part 310. For example, the upper end surface 315 is outward. The game ball may be formed so as to be difficult to ride up by being raised.

  In the embodiment, the end portion of the inner rail 42 fitted in the fitting groove 335 of the inner rail holding portion 336 is extended to the vicinity of the support portion 311 of the opening / closing portion 310, so that the weight portion 312 of the game ball is obtained. However, a partition wall or the like may be formed in advance between the weight portion 312 and the hitting ball guide passage 45 on the front surface of the mounting support portion 302.

  In the first and second embodiments, the thickness of the opening / closing part 310 is formed so as to gradually become thicker as the distance from the front side of the game board 6 increases. Although the launch ball contact surface 313 is provided so as to be inclined toward the front surface 6a side of the game board 6 with respect to the orthogonal surface T, the opening / closing part 310 is provided with respect to the orthogonal surface T on the front surface 6a side of the game board 6. The firing ball abutting surface 313 may be provided so as to be inclined toward the front surface 6a side of the game board 6 with respect to the orthogonal surface T.

  In the above embodiment, the ball return prevention device 300 is disposed on the inner side (inner rail 42 side) of the connecting part 46 so that the connecting part 46 is opened and closed by the opening and closing part 310. If the connection part 46 can be opened and closed by 310, you may provide in the outer side part (outer rail 43 side) of the connection part 46, or you may provide in both sides.
