Description

  The present invention relates to a gaming machine represented by a ball game machine such as a pachinko machine.

  A gaming machine such as a pachinko machine is generally provided with a game board that allows a game ball to flow down on the front surface, and various kinds of objects that guide the game ball in a predetermined direction on the front surface of the game board. . The arrangement of these items is greatly related to game playability, but the player's attention is concentrated on the position of the winning device, so the layout around this position is also highly interested. For this reason, a combination of various decorations and designs is arranged.

JP 2009-296 A

  However, there is a problem that the mechanical strength tends to decrease as a complex design or decoration is made by providing a large number of various protrusion shapes on an accessory, for example. In particular, since the game ball flows down more frequently around the winning device than in other places, the accessory placed at this position not only rolls and guides the game ball, Directly receiving a game ball that has fallen from the point of time becomes more frequent, and therefore, it is likely to be damaged by impact. That is, it is difficult to sufficiently satisfy both the decorativeness and mechanical strength of the accessory.

  The present invention has been devised in view of such problems, and an object of the present invention is to provide a gaming machine provided with an accessory on the front surface of a game board which is excellent in both decorativeness and mechanical strength.

In order to achieve the above object, the gaming machine according to the present invention
A gaming machine comprising a game board for causing a game ball to flow down on the front surface, and an accessory that guides the game ball in a predetermined direction on the front surface of the game board,
A winning opening is formed integrally with the accessory, and a receiving spherical wall is formed for receiving the flowing game ball. The posture is inclined with respect to the receiving spherical wall without being parallel to the board surface of the game board. The front wall which cross | intersects is formed.

In the present invention, the “act” includes both those provided with a member such as a character that moves in a movable manner and those provided with only a decoration without a member that moves in a movable manner.
The “winning entrance” is a winning entrance where a certain prize ball is paid out when a game ball enters, or a predetermined lottery when a game ball enters and a prize is won. It may be a winning opening that makes it easy for a game ball to be acquired when the opening of the game is opened. In such a case, when a gaming ball wins a winning opening, In addition to a payout, a prize ball may not be paid out.

  According to the configuration of the present invention, both the mechanical strength and decorativeness of the accessory can be improved with a simple configuration. When a winning opening is formed integrally with an accessory, a game ball flows down particularly frequently. Therefore, if a receiving surface is arranged on the accessory, the incoming game ball is directly received. Many things become easy to break. Therefore, by forming the front wall that intersects the receiving spherical wall while inclining with respect to the receiving spherical wall as in the configuration of the present invention, the front wall functions as a reinforcing rib of the receiving spherical wall, and thereby the machine of the receiving spherical wall. Effective strength can be improved effectively. Further, by inclining the front wall with respect to the board surface of the game board, it is possible to give the front wall a three-dimensional effect and to improve the decorativeness. In other words, both the mechanical strength of the receiving surface wall and the decorativeness of the front wall can be effectively improved by a simple configuration in which the front wall intersecting with the inclined posture with respect to the receiving surface wall is formed.

  In addition, the above-mentioned accessory of the present invention is provided in the upper part of the game area where the game ball flows down, or before the moment of the game ball entering the game area after the game ball is released, that is, far from the entrance of the game area. This is particularly effective when a part of an accessory is arranged at a position where the game ball can be abutted vigorously, such as when the game ball is provided at a position where the game ball abuts the game ball. By placing an accessory with a receiving spherical wall at a position where the game ball can vigorously abut, a nail protecting the accessory is provided around the accessory for the purpose of avoiding damage to the accessory, or as a cushioning material While reducing the cost of the entire gaming machine by reducing the need to provide rubber or elastomeric members, etc., the placement position and size of an accessory that has a winning opening that allows game balls to enter The degree of design freedom can be increased.

  According to the present invention, it is possible to impart both good mechanical strength and decorativeness to the accessory placed on the front surface of the game board.

  Hereinafter, the best mode of the present invention will be described in detail with reference to the drawings. Here, pachinko gaming machines (hereinafter simply referred to as “pachinko machines”) are listed as gaming machines.

(Configuration of front side of pachinko machine)
1 is a front view of the pachinko machine 10, FIG. 2 is a perspective view of the pachinko machine 10, and FIG. 3 is a perspective view of a front frame of the pachinko machine 10. As shown in FIGS. 1 and 2, the pachinko machine 10 includes an outer frame 11 that forms an outer shell of the pachinko machine 10, and an inner frame 12 that is supported on one side of the outer frame 11 so as to be opened and closed. I have. Below, the structure of the outer frame 11 and the inner frame 12 is demonstrated separately.

  The outer frame 11 is formed in a rectangular shape as a whole by a wooden plate material, and each plate material is assembled by a detachable fastener such as a small screw. The outer frame 11 may be made of a light metal such as resin or aluminum. This is because such a configuration can reduce the weight of the pachinko machine.

  On the other hand, the opening / closing axis of the inner frame 12 is set so as to extend vertically on the opposite side (left side of the pachinko machine 10 in FIG. 1) from the position where the handle (game ball launching handle 18 described later) is installed as viewed from the front of the pachinko machine 10. The inner frame 12 can be sufficiently opened to the front side with the opening / closing axis as the axis. If the opening / closing axis of the inner frame 12 is in the vertical direction on the handle installation location side (the right side of the pachinko machine 10 in FIG. 1), the game ball launching handle is opened when the inner frame 12 is opened. This is because the 18 heads and the like interfere with adjacent pachinko machines and card units (ball lending units), and the inner frame 12 cannot be fully opened. The inner frame 12 is made of a synthetic resin, specifically, ABS (acrylonitrile-butadiene-styrene) resin. By doing so, the advantages of high viscosity and high impact resistance and low cost production are exhibited.

  Further, the inner frame 12 has a lower pan unit 13 at the lowermost part thereof, and a front frame set 14 attached to the left and right sides of the inner frame 12 so as to be openable and closable about a vertical opening / closing axis, and a resin base ( (Not shown) and a game board 30 described later attached to the rear side of the resin base. Each of these configurations will be described in detail below.

  The lower plate unit 13 is fixed to the front frame base member as a part of the front frame set 14. On the front side of the lower plate unit 13, a lower plate 15, a ball removal lever 17, a game ball launching handle 18, and an effect button 79 are provided. The lower tray 15 serving as a ball receiving tray is provided at substantially the center of the lower tray unit 13 and plays a role of stopping a game ball discharged from the discharge port 16 when the upper tray described later becomes full. is there. The ball removal lever 17 is for removing a game ball in the lower tray 15, and by moving the ball removal lever 17 to the left in FIG. 1, a predetermined location on the bottom surface of the lower tray 15 is opened. The game ball stopped in the lower plate 15 can be discharged to the player's ball storage box (dollar box) through the opening on the bottom surface of the lower plate 15. The game ball launching handle 18 is disposed so as to protrude to the front side on the right side of the lower plate 15. In accordance with the operation of the game ball launching handle 18 by the player, the game ball is driven toward a game board 30 described later by a game ball launching device having a launch solenoid. At the upper part of the front frame set 14, a sound output port 24 for outputting sound from a speaker is provided.

  On the other hand, an upper plate 19 as a receiving tray for game balls is provided integrally with the front frame set 14 at a lower portion of the front frame set 14 (above the lower plate 15 described above). The upper tray 19 is a ball receiving tray for temporarily storing the game balls and guiding them to the game ball launching device 38 while aligning them in a line. In addition, an effect button 79 for the player to perform an operation such as changing the background of the decorative symbol display device 42 is provided at the lower left of the upper plate 19.

  In addition, the front frame set 14 is provided with light emitting means such as various lamps around it (for example, a corner portion). These light emitting means play a role of enhancing the effect of the game during the game by changing and controlling the light emission mode such as lighting and blinking according to the change of the game state in the big hit game state or the like. For example, at the periphery of the window portion 101, an annular illumination portion 102 containing a light emitting means such as an LED is provided symmetrically, and lighting or blinking in the big hit gaming state, it is in a big hit gaming state It is the structure which alert | reports.

  In addition, a ball lending operation unit 120 is disposed below the window unit 101, and the ball lending operation unit 120 is provided with a ball lending button, a return button, and a frequency display unit. When the ball lending operation unit 120 is operated with a bill or a card inserted in a card unit (ball lending unit) (not shown) arranged on the side of the pachinko machine 10, a game ball is lent according to the operation. Done. The ball lending button is operated to obtain a lending ball based on information recorded on a card or the like (recording medium), and the lending ball is supplied to the upper plate 19 as long as there is a remaining amount on the card or the like. The The return button is operated when requesting the return of a card or the like inserted into the card unit. The frequency display section displays remaining amount information such as a card. Note that the ball lending operation unit 120 is not required for a pachinko machine in which a game ball is directly rented from the ball lending device unit to the upper plate without using a card unit, that is, a so-called cash machine. Therefore, a decorative seal or the like is attached to the installation portion of the ball rental operation unit 120. Thereby, the common use of the lending operation unit of the pachinko machine using the card unit and the cash machine can be achieved.

  Next, the configuration of the game board 30 will be described with reference to FIGS. 4 and 5. 4 is a front view showing the configuration of the game board 30, and FIG. 5 is a perspective view showing the configuration of the game board 30.

The power failure monitoring circuit 542 monitors the DC stable voltage of 24 volts, which is the maximum voltage output from the power supply unit 541, and determines that a power failure (power shutdown) occurs when this voltage is less than 22 volts. The power failure signal SG1 is output to the main controller 261 and the payout controller 311. By the output of the power failure signal SG1, the main controller 261 and the payout controller 311 recognize the occurrence of the power failure and execute the NMI interrupt process. Note that the power supply unit 541 outputs a voltage of 5 volts, which is a drive voltage of the control system, for a time sufficient to execute the NMI interrupt processing even after the DC stable voltage of 24 volts becomes less than 22 volts. Is maintained at a normal value. Therefore, the main controller 261 and the payout controller 311 can normally execute and complete the NMI interrupt process.

The RAM erase switch circuit 543 is a circuit that outputs a RAM erase signal SG2 for clearing backup data to the main controller 261 and the payout controller 311 when the RAM erase switch is pressed. Note that transmission of a signal to the payout control device 311 is performed via the main control device 261.
When the RAM erase signal SG2 is input when the pachinko machine 10 is turned on, the main control device 261 and the payout control device 311 clear the respective backup data.

  The reset circuit 544 is a circuit that outputs a reset signal in order to initialize the main control device 261, the payout control device 311, the sub control device 262, and the display control device 45.

It has come to be given.

  Here, the display contents of the special symbol display device 38, the normal symbol display device 41, and the decorative symbol display device 42 will be described. In the pachinko machine 10 of the present embodiment, a special symbol displayed on the special symbol display device 38 as a symbol for showing the occurrence of the jackpot to the player, and a decorative symbol displayed on the decorative symbol display device 42. Two types are provided. The decorative symbol is a symbol that changes in synchronization with the special symbol. The decorative symbol starts changing at the same time (or almost at the same time) as the special symbol starts to change, and at the same time (or almost at the same time) as the special symbol changes. To stop the fluctuation. This decorative design is provided in order to provide a player with a variety of display effects so that the player is not bored.

  First, the display contents of the special symbol display device 38 will be described. The special symbol variation display is expressed by a change in the lighting pattern of the nine LED segments. The variation display of the special symbol is started based on winning of the game ball to the start winning device 33, and the variation display of the special symbol is simultaneously stopped after a certain time. After the stop, a lighting pattern indicating a big hit or a lighting pattern indicating a loss is displayed. In the case of a loss, a variation display is performed again based on winning to the start winning device 33. The number of times that the game ball has won the start winning device 33 is held up to a maximum of 4 times, and the number of times that the game ball is held is lit and displayed on the hold lamp 800a of the special symbol hold display device 800.

  Next, display contents of the decorative symbol display device 42 will be described. On the display screen of the decorative symbol display device 42, for example, three decorative symbol columns Z1 to Z3 are displayed in three display areas divided into an upper stage, a middle stage, and a lower stage. These decorative symbol rows Z1 to Z3 are scroll-displayed from right to left. The decorative symbol is composed of, for example, a main symbol composed of numbers “1” to “9” and a sub symbol smaller than the main symbol, and a symbol row of the decorative symbol is formed by each of the main symbol and the sub symbol. In each symbol row formed with decorative symbols, the main symbols are arranged in ascending or descending order of numbers, and sub-designs are arranged between the main symbols. When a winning to the start winning device 33, that is, a start winning occurs, the decorative symbol is displayed in a variable manner, and the variable display is stopped after a lapse of a certain time according to the changing pattern. 3 nine decorative symbols are displayed as a display result. In the variable display won in the big win lottery, the display control device 45 controls the three main symbols so that they stop on a vertical or diagonal straight line among the nine decorative symbols. The jackpot is indicated. On the other hand, in the variable display out of the big hit lottery, the display control device 45 controls the game so that three identical main symbols do not stop vertically or diagonally among the nine decorative symbols. The occurrence of detachment is shown to the person.

  Next, display contents of the normal symbol display device 41 will be described. The normal symbol variation display is expressed by alternately lighting the first lamp (appearance is ◯ shape) and the second lamp (appearance is X shape). The normal symbol variation display is started on the condition that the game ball passes through the second start winning device 34, and the regular symbol variation display stops after a certain period of time. And when it stops by a 1st lamp | ramp, it is comprised so that the 1st start prize-winning apparatus 33 may be in an operation state only for predetermined time (open | released). The number of times that the game ball has passed through the second starting prize-winning device 34 is held up to a maximum of 4 times, and the number of times that the game ball is held is displayed on the hold lamp 801a of the normal symbol hold display device 801.

  Next, the operation of the pachinko machine 10 configured as described above will be described. In this embodiment, the MPU 501 in the main control device 261 uses a variety of counter information during the game to perform a jackpot lottery, a symbol display setting of the special symbol display device 38, and the like. Specifically, a counter group related to the special symbol and a counter group related to the normal symbol are provided. First, a counter group related to special symbols will be described. As a group of counters related to the special symbol, the jackpot random number counter C1 used for the jackpot lottery, the jackpot symbol counter C2 used for the selection of the jackpot symbol of the special symbol display device 38, and the special symbol display device 38 fluctuate. Stop pattern selection counter C3 used for selection of stop patterns (corresponding to reach lottery of reaching or completely losing in the variation of decorative symbols) and initial value setting of jackpot random number counter C1 An initial value random number counter CINI1 and variation type counters CS1 to CS3 for determining a type used for variation pattern selection are provided.

  Here, the variation pattern means each pattern (form) in a case where features having common features of variation display are divided.

  Each of the counters C1 to C3, CINI1, CS1 to CS3 is a loop counter that adds 1 to the previous value every time it is updated, and returns to 0 after reaching the maximum value. Each counter is updated at short time intervals, and the updated value is appropriately stored in a counter buffer set in a predetermined area of the RAM 503. The RAM 503 is provided with a holding ball storage area 700 including one execution area and four holding areas (holding first to fourth areas). In each of these areas, a game to the start winning device 33 is performed. The values of the jackpot random number counter C1, the jackpot symbol counter C2, and the stop pattern selection counter C3 are stored in accordance with the winning timing of the ball.

Next, the specific contents of each counter will be described in detail.
The jackpot random number counter C1 is configured such that, for example, 1 is sequentially added within a range of 0 to 738, and after reaching the maximum value (that is, 738), it returns to 0. In particular, when the jackpot random number counter C1 makes one round, the value of the random number initial value counter CINI1 at that time is read as the initial value of the jackpot random number counter C1. Note that the random number initial value counter CINI1 is configured as a loop counter that is updated in the same range as the big hit random number counter C1 (value = 0 to 738), and is updated once every timer interruption and within the remaining time of normal processing. Will be updated repeatedly. The jackpot random number counter C1 is updated periodically (once every timer interruption in this embodiment), and stored in the reserved ball storage area 700 of the RAM 503 at the timing when the game ball wins the start winning device 33. The number of random number values that are jackpots is set at low probability and high probability, and the number of random numbers that are jackpots at low probability is 2, and the value is “373, 727” There are 14 random numbers that are big hits at high probability, and the values are “59, 109, 163, 211, 263, 317, 367, 421, 479, 523, 577, 631, 683, 733”. is there. High probability means a state in which a special symbol combination is a jackpot due to the combination of a specific symbol that is a predetermined probability variation symbol and the subsequent jackpot probability has increased as added value, so-called probability change. Time (when the probability is low) refers to a case where the probability variation state is not such.

  Further, in the pachinko machine 10, when a random number value other than the jackpot random number value (that is, a random number value that falls outside) is a value that is lower than a specified value (for example, 369), for example, Opening and closing blades 89R and 89L of a center accessory 83 to be described later are opened. In other words, even if the jackpot lottery by the jackpot random number counter C1 is unsuccessful, the opening and closing blades 89R and 89L can be opened to enter the center accessory 83 (hereinafter referred to as “small jackpot”). ) Is additionally secured, and through this small hit, the game ball will also successfully win the V winning port 77P in the center bonus 83 and secure a chance to win a big hit It has come to be. In this way, the internal lottery is made so that not only a big win but also a small win can be won, and the internal lottery is made directly in the lottery. There are two chances of winning the game in two patterns: winning the winning prize port 77P and winning the winning pattern. This makes the game more diverse and interesting.

  The jackpot symbol counter C2 determines a symbol at the time of a jackpot when the special symbol display device 38 stops changing the special symbol. For example, the jackpot symbol counter C2 is incremented one by one within a range of 0 to 4, and the maximum value (that is, 4 ), And then it returns to 0. For example, when the value of the jackpot symbol counter C2 is “0” or “1”, nine LED segments are stopped at a specific lighting pattern, and the combination of stop symbols in this case is a non-specific symbol (normally Of jackpot symbol).

  When the value of the jackpot symbol counter C2 is “2”, “3”, “4”, the nine LED segments stop in a specific lighting pattern different from the above, and the stop symbol of this case The combination means a specific symbol (probability variation symbol).

  The jackpot symbol counter C2 is updated periodically (once every timer interruption in this embodiment), and stored in the reserved ball storage area 700 of the RAM 503 at the timing when the game ball wins the start winning device 33.

  The stop pattern selection counter C3 is, for example, incremented by 1 in the range of 0 to 238, and returns to 0 after reaching the maximum value (that is, 238). In the present embodiment, the special symbol variation display is configured to be expressed by nine LED segments. Therefore, in the case of the special symbol, there is no concept of reach, and a stop pattern corresponding to reach is designated as a stop pattern selection counter C3. It is decided to decide. On the other hand, in the case of a decorative symbol, since three decorative symbols are stopped, there is a reach. Therefore, in the case of a decorative design, the reach lottery is determined by the stop pattern selection counter C3. That is, in the case of a decorative design, after the reach has occurred, the final stop symbol is shifted by one shift before and after the reach symbol, and the stop symbol is stopped before and after the reach symbol. It is decided to draw “reach other than front / rear off” to stop and “complete out” that does not cause reach. For example, the stop pattern selection counter C3 = 0 to 201 corresponds to complete detachment, the stop pattern selection counter C3 = 202 to 208 corresponds to anteroposterior detachment reach, and the stop pattern selection counter C3 = 209 to 238 lies other than detachment anteroposterior. Applicable.

  Here, “reach” refers to a combination of symbols that stop before the decorative symbol displayed on the display screen of the decorative symbol display device 42 starts changing display, and the combination of symbols that stop first is the same symbol (in a decorative symbol having a plurality of effective lines). A combination of jackpot symbols, suggesting to the player that the jackpot will be a big win depending on the display result of the symbols that are the same symbol on any active line) and satisfy the jackpot condition Is a display that makes a player expect the game, and is a type of entertainment production. An interesting effect is that a predetermined symbol represented by reach is displayed on the display screen of the decorative symbol display device 42 in the middle of variable display, a specific sound is output from a speaker, or a vibration motor is used. This is an effect that causes the player to expect that the display result after the change display will be a big hit with the change display, such as vibrating the game ball launch handle 18.

  The stop pattern selection counter C3 is periodically updated (once every timer interruption in this embodiment) and stored in the reserved ball storage area 700 of the RAM 503 at the timing when the game ball is won by the start winning device 33.

The variation type counter CS1 is, for example, incremented by 1 within a range of 0 to 198, and returns to 0 after reaching the maximum value (that is, 198). The variation type counter CS2 is, for example, incremented by 1 within a range of 0 to 240, and returns to 0 after reaching the maximum value (that is, 240). For example, the variation type counter CS3 is incremented by 1 within a range of 0 to 162, for example, and reaches a maximum value (that is, 162) and then returns to 0.
The variation type counter CS1 determines a rough symbol variation mode such as the reach type such as normal reach, super reach, premium reach, etc., and the variation type counter CS2 further refines the symbol such as normal reach A, normal reach B, etc. The variation mode is determined, and the variation type counter CS2 determines, for example, the addition / subtraction of the variation time in the case of a slip stop variation. Therefore, a variety of variation patterns can be easily realized by combining these variation type counters CS1 to CS3.

  The counters CS <b> 1 to CS <b> 3 are updated once every time a normal process to be described later is executed once, and are repeatedly updated even within the remaining time in the normal process. Then, the buffer values of the counters CS1 to CS3 are acquired when determining the variation pattern at the start of variation of the special symbol by the special symbol display device 38 and the decorative symbol display device 42.

  Next, a counter group related to normal symbols will be described. The counter group related to the normal symbol includes a winning random number counter C4 used for winning lottery and an initial value random number counter CINI2 used for setting an initial value of the winning random number counter C4.

  The hit random number counter C4 is a loop counter that adds 1 to the previous value every time it is updated, and returns to 0 after reaching the maximum value. The counter is updated at short time intervals, and the updated value is appropriately stored in a counter buffer set in a predetermined area of the RAM 503. The RAM 503 is provided with a holding ball storage area 701 including one execution area and four holding areas (holding first to fourth areas). In each of these areas, the second start winning device 34 is provided. The value of the hit random number counter C4 is stored in accordance with the passing of the game ball.

  Next, the specific contents of the winning random number counter C4 and the initial value random number CINI2 will be described in detail. The winning random number counter C4 is, for example, incremented one by one within a range of 0 to 250 and reaches 0 after reaching the maximum value (that is, 250). When the winning random number counter C4 makes one round, the value of the winning initial value random number counter CINI2 at that time is read as the initial value of the winning random number counter C4. The initial value random number counter CINI2 is configured as a loop counter that is updated in the same range as the winning random number counter C4 (value = 0 to 250), and is updated once per timer interrupt and within the remaining time of normal processing. Will be updated repeatedly. The winning random number counter C4 is updated periodically (once every timer interruption in this embodiment), and stored in the reserved ball storage area 701 of the RAM 503 at the timing when the game ball passes through the second start winning device 34. The number of random number values hit by the hit random number counter C4 is 149, and the value is “5 to 153”.

  In addition, the magnitude | size and range of each counter are only examples, and can be changed arbitrarily. However, if importance is attached to irregularity, the big hit random number counter C1, the stop pattern selection counter C3, the hit random number counter C4, and the variation type counters CS1 to CS3 are all different prime numbers and are not synchronized in any case. It is desirable to leave.

The details of each control process executed by the MPU 501 in the main controller 261 will not be described here.
However, in summary, as described above, by winning the start winning device 33, the main control device 261 performs a lottery with a predetermined probability, and when winning, it shifts to a special gaming state. Thus, the variable winning device 32 enters a winning ball receiving state.

(Variable winning device and collection unit)
In this embodiment, the variable winning device 32 is configured as follows.

  The upper left incoming ball portion 92L includes a ball receiving portion 93L, a left opening / closing blade 89L, a sensor housing chamber 94L, an upper left incoming ball sensor 95L, and a ball release portion 96L. The ball receiving portion 93L has a substantially rectangular parallelepiped having a lateral width and a longitudinal width slightly larger than the diameter of the game ball and a height slightly larger than twice the diameter of the game ball, and the left side surface portion is almost entirely dropped. It is a hollow portion that is shaped so as to have an open outer shape, and is arranged and formed so that the upper end stands up in contact with the left end of the flange 90. A notch (not shown) through which one game ball can pass is formed in the lower portion of the rear side surface of the ball receiving portion 93L. On the rear side of the ball receiving portion 93L, there is formed a rectangular parallelepiped sensor housing chamber 94L having a vertically long rectangular shape substantially corresponding to the shape of the rear side surface of the ball receiving portion 93L and having a slight thickness in the front and rear. The upper left ball entering sensor 95L is accommodated in the sensor accommodating chamber 94L (see FIG. 9 or FIG. 11). A ball release portion 96L extending rearward in a substantially rectangular tube shape is formed from the lower portion of the storage chamber 96L. The bottom surface portion of the ball discharge portion 96L extends rearward from the rear side surface of the sensor housing chamber 94L by a length substantially corresponding to the diameter of one game ball, and the rear side is open. The ball receiving portion 93L, the sensor accommodating chamber 94L, and the ball releasing portion 96L are integrally formed of a transparent resin.

  On the left side of the ball receiving portion 93L, a left opening / closing blade 89L is disposed. The left open / close blade 89L has a front and rear width slightly larger than the diameter of the game ball, and is a movable blade having a generally claw shape that tapers upward in a front view and extends slightly curved to the right. The left drive shaft 140L is fixed to the tip of the left drive shaft 140L and is driven by a left solenoid 138L, which will be described later, via the drive shaft 140L to rotate between a closed position standing upward and an open position tilted leftward. It opens and closes as you do. When the left opening / closing blade 89L is in the closed position, the ball receiving portion 93L is closed, and the outer side surface (left side surface) forms a slope connecting to the left end of the bowl 90 to guide the game ball to flow downward to the left. On the other hand, when in the open position, the game ball is received by the inner side surface (right side surface) and guided to enter the ball receiving portion 93L.

  The upper right incoming ball portion 92R is configured to be bilaterally symmetric with the upper left upper incoming ball portion 92L. For this reason, in the figure, reference numerals corresponding to the respective portions are given, but description thereof is omitted.

  On the front surface of the inner edge wall 84P of the support frame member 84, fixed blades 97R and 97L are respectively arranged and fixed below the left and right opening and closing blades 89R and 89L. Each of the fixed wings 97R and 97L has a front and rear width that is slightly larger than the diameter of the game ball, and extends from the position directly below the opening and closing blades 89R and 89L while being slightly inclined downward to the left or right. The fixed wings 97R and 97L guide the game ball so as to roll from the lower left to the lower right and serve as a fixed structure that constitutes the design of the upper left portion and the upper right portion of the front surface portion of the center accessory 83. Yes.

  The inner edge wall 84P of the support frame member 84 extends downward from the attachment position of the left fixed wing 97L with a width substantially equal to the length of the fixed wing 97L, and the normal symbol is positioned immediately below the fixed wing 97L. A display device 41 is disposed (not shown in FIG. 20), and an LED substrate that is a light source of the normal symbol display device 41 is arranged on the back side of the inner edge wall 84P at the position (not shown). On the inner edge wall 84P, a partition plate 98 is fixed at a position slightly below the right end of the left fixed wing 97L. The partition plate 98 is a plate member that has a width that is slightly larger than the diameter of the game ball and extends horizontally. The partition plate 98 extends further from the inner edge wall 84P to the inner side (right side), and the tip of the partition plate 98 is in the support frame member 84. It is arranged to reach a position slightly to the right of the center. The partition plate 98 is located at the upper end portion of the lower step portion 83B of the center accessory 83.

  The inner edge wall 84P of the support frame member 84 extends in an arc shape along the substantially circular outer periphery of the support frame member 84 further downward from the height position of the partition plate 98, and has a substantially rectangular shape on the way. The translucent openings 99 and 99 are formed so as to be juxtaposed in the vertical direction. An LED substrate 111 is disposed behind the light-transmitting openings 99, 99, and light emitted from the LEDs mounted on the LED substrate 111 corresponding to the upper and lower light-transmitting openings 99, 99 is transmitted through the light-transmitting openings 99, 99. It is designed to irradiate forward. Also on the right side of the support frame member 84, the light-transmitting openings 99 and 99 and the LED substrate 111 and the light-transmitting openings and the LED substrate configured to be bilaterally symmetrical are arranged (not shown).

  The support frame member 84 is a portion in which a substantially upper end portion in a front view is missing along a substantially circular outer periphery of the support frame member 84 from directly below the tip of the left fixed wing 97L to just below the tip of the right fixed wing 97R. A circumferential wall 112 is formed extending in a circular shape so as to have a constant longitudinal width substantially equal to the longitudinal width of the fixed wings 97R and 97L.

  The inner peripheral wall 113 extends forward from the extending end edge (inner end edge) of the inner edge wall 84P on the right side of the support frame member 84, and forms a groove-shaped portion having a U-shaped cross section along with the peripheral wall 112 and the inner edge wall 84P. ing. The inner peripheral wall 113 extends from the lower right position of the support frame member 84 to a position slightly below the left end of the right fixed wing 97R while curving in a generally arcuate shape in a front view. On the inner edge wall 84P above the upper end portion of the inner peripheral wall 113, the first magnetic sensor 114 is disposed and fixed. The first magnetic sensor 114 has a shape that extends somewhat long in a prismatic shape, and has a configuration in which wiring is connected to one end by a connector, and the tip (end opposite to the wiring connection end) is the direction of the detection target. Magnetism can be detected by placing it vertically (vertically) or by placing it in a direction perpendicular to the direction of the object to be detected (horizontal placement), but the vertical orientation is slightly more sensitive. It has become. In addition to the tip end side, the wiring connection end side has a detection range that swells outward along the length direction and forms a slightly longer oval-shaped area. Can be done. The first magnetic sensor 114 is disposed (vertically placed) with a tip facing a ball path 127R of a ball guide 127 in an upper stage unit 86 described later, and the ball path 127R and the vicinity thereof are within the detection range. It is like that.

  A ball guide tube portion 115 is disposed on the front surface of the inner edge wall 84 </ b> P on the left side of the support frame member 84. The ball guide tube portion 115 basically has a tube shape through which one game ball can circulate, is made of a light-transmitting resin, and has a shape imitating a gas or liquid delivery tube. The upper portion of the ball guide tube portion 115 extends in a straight line while tilting slightly upward to the right to form a horizontal portion 115C, and the tip portion (right end portion) is a gaming ball further than the right end of the partition plate 98. One ball extends to the right, and is bent upward and slightly extends. The horizontal portion 115C of the ball guide tube portion 115 has a shape in which the rear side including the tip portion is opened, and is closed by the partition plate 98. However, the right end of the partition plate 98 does not reach this position at the tip of the guide tube portion 115, and the rear side of the guide tube portion 115 is further to the right than the right end of the partition plate 98. The game ball is not blocked and opened by a width of about one game ball so as to communicate with the rear side. The left end (lower end) of the horizontal portion 115C in the above-mentioned ball guide tube portion 115 extends in an arc shape along the inner edge wall 84P of the support frame member 84 to form a descending portion 115D. Only the front half with the half opened is continuously formed integrally with the left end of the horizontal portion 115C, but a separate semi-tubular member corresponding to the front half is attached from the rear side. This separate semi-tubular member is also combined to form a tubular descending portion 115D as a whole. The lower end of the descending portion 115D in the above-mentioned ball guide tube portion 115 is bent backward and slightly extends, and is opened toward the rear. The ball guide tube portion 115 is once a terminal at the lower end portion of the lowering portion 115D as an integral portion continuing from the horizontal portion 115C, but is a separate retracted portion extending linearly rearward adjacent to this. The ball guide tube portion 115 is configured to communicate with the portion 115B, and the retracted portion 115B is combined with the horizontal portion 115C and the descending portion 115D. The retracted portion 115B is configured such that the left side surface portion of the tubular member extending in the front-rear direction is opened, is fixed to the inner surface of the lower end portion of the left side plate member 87L described later, and is closed by the left side plate member 87L. The lower portion of the rear end portion of the retreating portion 115B is cut out to form a cutout portion 115E so that the game ball can easily fall down.

  The front frame member 85 is a substantially annular shape in front view covering the inner edge wall 84P of the support frame member 84 from substantially the front, and is a cover member having a shape that bulges forward from the outer periphery to the inside, It is adapted to be fitted and fixed to the inside of the peripheral wall 112 from the front. The front frame member 85 is made of an opaque resin, and the upper right part and the upper left part are covered with a cover made of a light-transmitting resin at a total of four places, two on each of the left and right sides corresponding to the light-transmitting openings. Each of the broken window portions 85A is disposed, whereby the holding lamp 800a (see FIG. 4) is configured. In addition, the front frame member 85 includes the design of the front surface portion of the center accessory 83, including the window portion 85A constituting the holding lamp 800a.

  The side plate members 87R and 87L are substantially plate-like members that close the inner space of the lower step portion 83B of the center accessory 83 so as to cover the both sides from each side, and have a slightly circular width in the support frame member 84 with a slight front-rear width. It has a rectangular outer shape in a side view extending slightly vertically while curving in an arc shape along the outer periphery on both sides of the part. Each of the side plate members 87R and 87L has a configuration in which an outer layer member and an inner layer member made of an opaque resin are fitted. The inner layer member is formed such that a plurality of elongated window portions 87A extending in the front-rear direction are juxtaposed in a vertical direction, and each window portion 87A is covered with a cover made of a light-transmitting resin. An LED substrate is interposed between the outer layer member and the inner layer member (not shown), and light emitted from the LED mounted on the LED substrate passes through the window portion 87A of the inner layer member and enters the inside of the lower step portion 83B. It is designed to irradiate the space.

  The stage member 88 is a slightly oblong rectangular shape in plan view, and has a schematic shape in which a concave portion 88H that is slightly larger inward from the center of the rear long side portion into a substantially arc shape is formed. The resin molded body has a slightly complicated shape in each part, such as the passage 117 and various patterns. Protrusions 116 that protrude slightly rearward are formed on both sides of the recess 88H in the rear long side portion.

  On the upper surface of the stage member 88, a sphere extending from the left rear corner to the right rear corner so as to draw a roughly “h” -shaped trajectory in plan view while largely curving forward so as to bypass the recess 88H. A passage 117 is formed. As will be described later, the ball passage 117 has a movable width through which one game ball can freely roll and pass, and guide rails 117F and 117R are erected along both sides so that the game ball deviates. It is supposed not to. At the left rear end of the ball passage 117, a guide slope 117S is formed which has a rectangular shape in plan view and has an area where one game ball can be placed with a margin, and is inclined slightly downward from the left side to the right side. Of the guide rails 117F and 117R, the guide rail 117R provided along the rear side of the ball passage 117 extends to the position of the left end of the guide slope 117S and continues to the rear edge of the guide slope 117S. A ball stop wall 117D having a height and width slightly larger than the diameter of the game ball and protruding upward from the other portions of the guide rail 117R is formed at the left end. As shown in FIG. 9, the ball stop wall 117D is disposed so as to shield the opening at the rear end of the retreating part 115B in the ball guide tube part 115, and the guide slope 117S is formed in the notch 115E of the retreating part 115B. The game ball that is disposed below and has flowed down the retreating part 115B hits the ball stop wall 117D and falls downward from the notch 115E, and is guided into the ball path 117 by the guide slope 117S. Returning to FIG. 20, a return slope 117B that is substantially symmetrical with the guide slope 117S of the left rear end is formed at the right rear end of the ball passage 117, and the rear guide rail 117R is formed on the return slope 117B. It extends to the position of the right end and continues to the rear side edge of the return slope 117B. A right side plate member 87R is arranged on the right side of the return slope 117B, and the game ball that has reached the right rear end of the ball passage 117 climbs the return slope 117B and hits the inner side surface of the right side plate member 87R and turns back. After descending the return slope 117B, the ball passage 117 flows down in the opposite direction.

  The ball passage 117 extends at the center of the stage member 88 so as to pass through the front of the recess 88H, but the portion located in front of the recess 88H is generally inclined downward and the rear side is partially The guide rail 117R on the rear side is not formed at the intersection with the recess 88H, and the guide rail 117R on the rear side is not formed at the intersection with the recess 88H. Are opened over a width (a width slightly larger than three times the diameter of the game ball). That is, the intersection with the recess 88H becomes an open portion that is partially opened by forming the rear guide rail 117R with an interval (corresponding to the intersection with the recess 88H). In addition, the opening portion of the guide rail 117R is such that the ball passage 117 is inclined downward at this portion, so that when the game ball passes with a momentum, it easily falls off backward. In other words, the ball discharge guide portion 117E guides the game ball so as to drop backward.

  The ball passage 117 extends so as to consistently descend from the left rear end to the center and to consistently rise from the center to the right rear end. That is, from the transition of the height position, the left half and the right half in the case of bisecting at the center are respectively descending portions that descend from the end side toward the center side. Thereby, the game ball guided into the ball passage 117 from the left rear end portion of the ball passage 117, that is, the guide slope 117S, reciprocates between the left rear end portion and the right rear end portion of the ball passage 117 by its own weight. Roll to.

  In addition, as shown in FIG. 19, the ball passage 117 has a movable width that allows at least one game ball to roll and pass in any part, but maintains a constant movable width as a whole. I don't mean. The ball passage 117 extends slightly from the left rear end portion (guide slope 117S) to the inside, that is, the right side, and then bends approximately 90 ° to the front to substantially linearly form the left straight portion 118L. From the past, it curves to the right and extends to the vicinity of the front end of the stage member 88 while forming the left corner portion 119L, and then to the center of the stage member 88 with a slight curvature to the right. From this central portion, it extends to the right rear end portion (return slope 117B) so as to be almost symmetrical with the shape of the left half, and on the way, the right corner portion 119R and the right straight portion 118R. Is forming. In the overall shape of the spherical passage 117, the movable width is partially narrowed in the middle portion of the left corner portion 119L and the right corner portion 119R, and the portion where the movable width is minimized is schematically shown in FIG. As shown in the figure, the width W1 of the ball passage 117 is about 10 mm, which is slightly less than the diameter D1 (about 11 mm) of the game ball M1, and the extent beyond the minimum that allows the game ball M1 to pass smoothly is about Although it is secured, there is only a margin that can move in the width direction. That is, the position closest to the front side where the game ball M1 abuts on the upper end of the front guide rail 117F in the ball path 117 and the forward movement of the game ball M1 is restricted (hereinafter also referred to as “front limit position”); A position closest to the rear side (hereinafter also referred to as a “rear limit position”) in which the game ball M1 is in contact with the upper end of the rear guide rail 117R in the ball passage 117 and the rearward movement of the game ball M1 is restricted. The width (that is, the movable width) F1 in the range with the two ends is small. On the other hand, in each of the left corner portion 119L and the right corner portion 119R, the width gradually increases from the intermediate portion to both side portions, and the entire spherical passage 117 excluding both the corner portions 119R and 119L generally As shown schematically in FIG. 22, for example, in the left straight portion 118L and the right straight portion 118R, the width W2 of the ball passage 117 is equal to the diameter D1 of the game ball M1 (see FIG. 22). Not only about a trajectory on a substantially single line passing through the central portion in the width direction of the ball passage 117, but also in this way. A margin is secured to allow a trajectory that deviates somewhat from the central track to the side. That is, in the left straight portion 118L and the right straight portion 118R, the distance (that is, the movable width) F2 between the front limit position and the rear limit position is the front side in the intermediate portion between the left corner portion 119L and the right corner portion 119R. The width (that is, the movable width) F1 is larger than the range having both the limit position and the rear limit position as both ends. In other words, in terms of the planar shape of the ball passage 117, especially the width variation, the left corner portion 119L and the right corner portion 119R have a narrowed movable width F1 at the middle portion, so that the game ball M1 has a width. It is a restricting portion that is restricted so as to pass through a track on a substantially single line passing through the central portion in the width direction with almost no swing in the direction, such as the left straight portion 118L and the right straight portion 118R. The entire ball passage 117 excluding both corner portions 119R and 119L has a movable width F2 large enough to allow the game ball M1 to sufficiently move in the width direction without being restricted so as to pass through a substantially single track. The relaxed part is relaxed.

  On the upper surface of the stage member 88, four regions arranged in the left-right direction so as to be partitioned by the spherical passage 117 and the recess 88H are formed. Each region is made of a translucent resin having a decorative shape on the surface. The decorative member is fitted so as to cover the entire surface, and the LED board is disposed on the back side (lower side) of the decorative members 121R and 121L disposed at both ends (not shown). Production is performed by irradiating light upward through 121R and 121L.

  As shown in FIG. 9, the stage member 88 is disposed so as to lie slightly above the lower end in the lower step portion 83 </ b> B of the center accessory 83, and is fixed to the support frame member 84 and the front frame member 85. A bottom surface portion in the portion 83B is formed.

  The upper stage unit 86 shown in FIG. 20 constitutes an inner back part of the upper stage part 83T in the center accessory 83, which is arranged behind the front surface of the game board 30. FIG. As shown in the exploded perspective view of FIG. 24, the upper stage winning mechanism 123 is disposed inside the outer member 122, and the opening / closing blade driving portion 124 is disposed on the back surface portion. Corresponding to the shape of the upper step portion 83T in the center accessory 83, the outer member 122 has a substantially front shape that bulges upward from the bottom portion extending substantially linearly to the left and right, and the front surface is rearward from the lower end to the upper end. As a whole, it is a hollow resin-molded member that extends in the depth direction while being inclined, and has a front surface opened and the other five surfaces closed. The upper end surface portion of the outer shell member 122 has a shape that is rounded backward from the front end edge corresponding to the shape of the canopy 91 of the support frame member 84, and is fitted and integrated with the canopy 91. The top part (upper surface part) of the upper stage part 83T in the center accessory 83 is configured. A circular dot display device 21 using LEDs as light emitting elements is disposed and fixed at the upper end of the inner back wall of the outer member 122, and forward from the inner back of the upper end of the upper step portion 83T of the center accessory 83. It is designed to display a variation toward Furthermore, an LED substrate is disposed and fixed inside the inner wall of the outer member 122 located on the back side of the dot display device 21 (not shown), and light is emitted forward from both sides of the dot display device 21. Is directed to produce an effect. As shown in FIG. 20, the outer shell member 122 is fitted and fixed to the upper portion of the support frame member 84 from behind. Further, as shown in FIGS. 20 and 23, a hollow right-side protruding portion that protrudes from the lower end portions of both side walls of the outer shell member 122 so as to further expand into a substantially C shape in front view on both sides, and whose front surface is open. 23R and the left side protrusion part 23L are protrudingly provided. The lower end of the side wall of the right protrusion 23R is cut out in a rectangular shape from the front end to form a notch 23C. The notch 23C has a dimension that allows a game ball to pass therethrough, and the outer member 122 has a support frame. When fitted to the member 84 from the rear, the front surface of the right protrusion 23R is closed, and the front end of the notch 23C is also closed accordingly, so that a rectangular ball outlet is formed. Further, a ball discharge passage extending inward, that is, on the left side from the ball discharge port is formed, and the tip, that is, the left end, communicates with an upper discharge passage 130 in a support plate member 125 described later, as shown in FIG.

  The upper prize winning mechanism 123 is a mechanism that distributes the game balls into a game area advantageous for the player and a game area less advantageous than the game area in the upper stage 83T of the center bonus 83, as shown in FIG. As shown in FIG. 24, it is comprised by members, such as the support plate member 125, the rotary body 126, and the ball guide board 127. FIG.

  The support plate member 125 has a substantially rectangular shape and is formed into a dish shape with a peripheral wall extending slightly upward at the periphery. The support plate member 125 has a disk-like shape so as to slightly protrude upward at the center of the bottom surface. A turntable 128 is formed, and a shaft insertion hole 128H through which a rotation shaft of a right gear 137R described later is inserted is formed at the center of the turntable 128, and a position adjacent to the lower right of the shaft insertion hole 128H. From the position adjacent to the upper right of the shaft insertion hole 128H, and the upper stage winning path 129 that extends from the outer periphery of the rotating stage 128 to the lower right and extends linearly from the outer periphery to the front lower side. An upper discharge passage 130 is formed which extends to the lower right substantially parallel to 129 and extends in a straight line while being slightly inclined downward from the outer periphery of the turntable 128 to the side.

In the process of repeating the above, at first, the reciprocating motion passes through the discharge guide part 117E due to the momentum of descending the descending portion. When the ball is weak enough to not pass through the ball guide portion 117E, the game ball is guided to the ball guide portion 117E by its own weight and discharged to the rear side, that is, into the depression formed in the central portion of the stage member 88. Then, it flows into the lower central discharge groove 72E.

  At this time, the winning saddle member 77G of the lower prize winning member 77 is laid on the lower central discharge groove 72E and swings like a swing as described above. Since one ball can be accommodated with a slight margin, the width (left and right width) of the ball guide portion 117E is slightly larger than the three game balls as described above. The discharged game balls are captured by the winning prize pool portion 77G with a probability of approximately 1/3 and enter the V winning slot 77P. If the gaming balls are not captured by the winning prize pool portion 77G, the lower central discharge groove It flows into 72E and is discharged to the lower left or lower right. Here, the lower stage winning bar member 77, the second drive mechanism 76 for driving the lower stage winning bar member 77, and the like, play the game ball in the lower stage part 83B of the center accessory 83 together with the ball path 117 of the stage member 88. The lower prize winning mechanism is configured to distribute the game area advantageous to the player and the game area less advantageous than the game area.

Hereinafter, the operation of the center accessory 83 will be described.
In this pachinko machine 10, as described above, even if a lottery draw is lost, there is still a possibility of a small hitting. The opening / closing blades 89R and 89L of the accessory 83 are opened twice.

  As shown in FIGS. 42 and 43, when the game ball M2 enters the opened right opening / closing blade 89R or left opening / closing blade 89L, the game ball M2 enters the ball receiving portion 93R or the upper left entrance in the upper right entrance portion 92R. It is detected from the ball receiving portion 93L in the ball portion 92L that the ball has entered the center accessory 83 after passing through the upper right ball entering sensor 95R or the upper left ball entering sensor 95L. It flows down to the rear upper part of the ball guide board 127 in the upper stage winning mechanism 123 through the ball release part 96L in the 96R or upper left entrance part 92L. As described above, the game ball M2 flows down forward and downward on the ball guide board 127 and is guided into the ball passage 127R, and rolls so as to reciprocate left and right in the ball passage 127R. Then, it falls into the through-hole 127P, and a lottery (hereinafter also referred to as “upper distribution”) by the rotating body 126 is performed. In this upper stage allocation, as described above, when the game ball M2 enters the upper stage winning recess 126Y (one recess) among the three upper recesses 126Y and the upper stage discharging recesses 126N and 126N, the upper stage winning path 129 and is detected as a winning (winning) by the upper stage winning sensor 131. When a ball enters the upper stage discharging recesses 126N and 126N (two recessed parts), the upper stage discharging passage 130 is guided to the upper stage. It is detected by the discharge sensor 132 as being disconnected, passes through the outer member 122 of the center accessory 83, merges into the right sphere passage 27R of the right sphere passage member 26R, and is discharged downward. That is, in the rotating body 126, lottery (upper stage allocation) is performed with a winning probability of 1/3.

  While the game ball M2 rolls left and right in the ball passage 127R of the ball guide 127 and falls into the through hole 127P as described above, for example, the game ball M2 is rotated by bringing the magnet closer from the front. Although illegal actions such as guiding to the upper winning recess 126Y of the body 126 are likely to be performed, the first magnetic sensor 114 is arranged in the center role 83 with the tip facing the ball path 127R of the ball guide board 127 as described above (vertically placed) Therefore, the first magnetic sensor 114 can detect an illegal act using such a magnet.

  As shown in FIGS. 42 and 44, the game ball M2 guided in the upper winning path 129 and passing through the upper winning sensor 131 flows into the horizontal portion 115C of the ball guiding tube portion 115 from the front end portion (right end portion). Then, it flows down in the ball guide tube 115 and is guided to the left rear end of the stage member 88. In this process, the game ball M2 moves the front upper end portion of the lower step portion 83B of the center accessory 83 from the position slightly right to the left from the center, and then to the left side of the lower step portion 83B. It is guided downward along the inner periphery, and then the left lower end portion of the lower step portion 83B from the front end to the rear. That is, the direction is changed from the width direction to the height direction and the depth direction sequentially along the inner side surface of the lower step portion 83B, so that the lower step portion 83B is guided as widely as possible. As a result, the distribution distance of the game ball M2 becomes longer, and it takes more time to distribute the game ball M2, so that the expectation for the winning is longer and the excitement is excited, and the decoration A time for performing an effect by the symbol display on the symbol display device 42 is also secured. In addition, at this time, since the ball guide tube portion 115 has translucency, the game ball M2 that runs long in the ball guide tube portion 115 is visually recognized by the player and visually produced. An effect can be obtained.

  As described above, the game ball M2 guided on the stage member 88 repeatedly reciprocates between the left rear end portion and the right rear end portion in the ball passage 117. At this time, the game ball M2 that has fallen from the notch 115E in the upper ball guide tube 115 is a straight line on the left from the guide slope 117S at the left rear end, as schematically shown by the arrow A1 in FIG. The left straight portion 118L is a relaxed portion as described above, so that only the trajectory on a substantially single line passing through the central portion in the width direction of the ball passage 117 is guided into the portion 118L. Instead, it deviates somewhat from the center orbit to the side, and as shown by an arrow A2 in the figure, for example, it flows down so as to meander in the width direction while bouncing off at the guide rails 117F and 117R. In this way, unexpected behavior is imparted to the behavior of the game ball M2 to ensure interest. When the game ball M2 reaches the left corner portion 119L, the left corner portion 119L is a restricting portion as described above, so that the game ball M2 almost swings in the width direction as indicated by an arrow A3 in FIG. Without passing, the left corner portion 119 </ b> L is passed through the left corner portion 119 </ b> L after being regulated so as to pass through a track on a substantially single line passing through the central portion in the width direction. At this time, since the centrifugal force acts on the game ball M2 by the curved shape (curve) of the left corner portion 119L while passing through the left corner portion 119L, the game ball M2 enters the left corner portion 119L and thereafter. Will roll along the inside of the front guide rail 117F (while being pressed against the front guide rail 117F), as indicated by arrow A3. Thereafter, the game ball M2 climbs from the right corner portion 119R to the right straight portion 118R through the ball discharge guide portion 117E, bounces back on the inner side surface of the right plate member 87R at the return slope 117B, and turns back again to the right straight line. Although the right straight portion 118R is also a loosened portion, it is guided into the portion 118R and flows forward. As in the case of the left straight portion 118L, it can be somewhat freely moved from the center track to the side. For example, the left corner portion 119R can also flow down in a meandering manner as indicated by an arrow A4 in the figure, and the right corner portion 119R is also a restricting portion. As in the case of 119L, as shown by the arrow A5 in the figure, it is restricted to pass through a track on a substantially single line passing through the central portion in the width direction and passes through the right corner portion 119R. It made.

  At this time, if, for example, as schematically shown in FIG. 45 (b), the ball passage 156 does not have the restricting portion as described above, but is formed to be a relaxing portion in the entire area. The game ball M3 also deviates somewhat from the center track to the side at the left corner portion 157L or the right corner portion 157R, for example, as shown by arrow A6 in FIG. It will pass in a meandering direction. In this case, since the course of the game ball M3 after passing through the left corner portion 157L or the right corner portion 157R is not constant, and it cannot be predicted in which direction it will go after this, it can be said that the excitement is excited at this point. However, on the other hand, as shown by, for example, the arrow A7 in the figure, the game ball M3 is likely to go straight to the rear of the ball discharge guide portion 156E and fall off the ball discharge guide portion 156E. Even if the game ball M3 has not yet repeatedly reciprocated in the ball passage 156, the game ball M3 is immediately discharged from the ball discharge guide portion 156E while leaving sufficient momentum to reciprocate thereafter. This is likely to greatly impair the interest.

  On the other hand, in the ball passage 117 of the pachinko machine 10, the game ball M2 is restricted so as to pass the trajectory on a substantially single line passing through the central portion in the width direction at the left corner portion 119L and the right corner portion 119R as described above. Therefore, the path of the game ball M2 after passing through the left corner portion 119L or the right corner portion 119R is also restricted on the extension of the trajectory, and therefore the game ball M2 is directed to the rear side of the discharge guide portion 117E. It is possible to repeat the reciprocation through the ball discharge guide portion 117E while the game ball M2 maintains a certain momentum or more without going straight and dropping off the ball discharge guide portion 117E. It has become. In other words, the game ball M2 is controlled by the left corner portion 119L or the right corner portion 119R to be controlled to reciprocate through the discharge guide portion 117E without deviating from the reciprocating orbit (that is, rectified. ), Therefore, the ball rolls longer on the ball passage 117 so that the interest is maintained.

  When the momentum is attenuated to some extent while the game ball M2 repeats reciprocation in the ball passage 117 as described above, the game ball M2 is guided to the ball discharge guide portion 117E and discharged to the rear side, and falls into the lower central discharge groove 72E. Go. If the game ball M2 is successfully captured by the winning bowl part 77G and enters the V winning opening 77P as indicated by an arrow A8 in FIG. In the case where it is guided into the lower prize winning groove 48G at the same time, passes through the ball outlet 48A, is discharged downward while being detected as a winning (winning) by the lower prize winning sensor 49, and is not captured by the prize winning portion 77G. Then, it flows into the lower central discharge groove 72E, is guided to the lower left or lower right, and is detected as a detachment by the lower left vent sensor 46L or the lower right vent sensor 46R, and from the lower left outlet 80L or the lower right outlet 80R. It will be discharged downward. That is, as the game ball M2 falls from the ball guide portion 117E of the ball passage 117 to the lower center discharge groove 72E, the game ball M2 is hit by the winning bowl portion 77G of the lower step winning passage member 48 that swings in a swinging manner. Distribution (hereinafter also referred to as “lower distribution”) is made, and the winning probability in this lower distribution is about 1/3 as described above.

  As described above, when the game ball M2 enters the center accessory 83 from the upper right entrance portion 92R or the upper left entrance portion 92L with a small hit, the game ball M2 passes through the center accessory 83. It will flow downward while being guided in the direction, and in the middle of that, the upper and lower halves will be made in succession, and it will be a success (ie with a winning probability of about 1/9) in any allocation. When the player enters the V winning port 77P, the game state shifts to the special game state with a big win. As the game ball M2 flows down through the center accessory 83 in this way, the result of the upper distribution or the lower distribution is detected by the sensors arranged in each part, and based on the detection result, the center accessory 83 is detected. The approximate progress of the game ball M2 in the game is also grasped, and according to this, the symbol display by the decorative symbol display device 42, the variable display by the dot type display device 21, the rotation operation by the effect unit 73T of the V winning movable body 73 and the light emission. In addition, various effects are produced by light emission, sound, etc. by the LED substrate of each part.

  The front surface side of the accessory base material 148M (flange 148F) has the same front shape as the first light diffusion member 151 and the second light diffusion member 152, and the first light diffusion member 151 and the second light diffusion member. A recess 148E is formed that is recessed by a depth substantially equal to the combined thickness of the member 152, and the first light diffusing member 151 and the second light diffusing member 152 are threaded portions 151G of the first light diffusing member 151. Is inserted back and forth through the screw insertion portion 152G of the second light diffusion member 152, and the screw insertion portion 151G of the first light diffusion member 151 is inserted into the screw insertion portion 148G of the accessory base material 148M. Thus, it is fitted in the recess 148E, and is fastened and fixed by screwing a screw into the screw-in portion 151G from the back side of the screw insertion portion 148G.

  As shown in FIGS. 58 and 59, the decorative projecting body 153 has a generally claw-shaped front surface corresponding to most of the accessory base material 148M (flange 148F) except for the lower end of the claw-shaped portion. From the outer periphery of the front surface, a peripheral wall 153P having an extension height that is slightly larger than the diameter of the game ball extends rearward. The decorative protrusion 153 is integrally formed as a whole, but has a shape in which a right side 153R having a relatively small volume projects rightward from a right side of the left side 153L having a relatively large volume. . As shown in FIGS. 60 to 62, the left portion 153L is formed by continuously forming two regions in the width direction in which the front wall has a cross-sectional arc shape and slightly bulges forward. As shown in FIG. 59, these two regions are formed in a shape extending in a substantially claw shape vertically while being adjacent to the left and right. Of the left and right areas of the left side 153L, the center of the front of the right area has a decorative protrusion 153F that is embossed in the shape of a star and plated on the surface. The upper and lower portions of the rear surface (inner surface) are respectively formed with two engraved decorative recesses 153B that imitate the star (only one in the lower portion). In addition, two embossed decorative protrusions 153S each having an ellipse in front view and plated on the surface are juxtaposed on the lower portion of the left edge on the front surface of the right region and the upper end portion on the front surface of the left region. Is formed. Furthermore, a concave lens portion 153M that is recessed in an elliptical shape in front view and slightly inwardly curved at the center of the rear surface (inner surface) of the right region and the upper portion of the rear surface (inner surface) of the left region, respectively. Two or three large and small ones are juxtaposed. The peripheral wall 153P at the upper end of the left portion 153L is slightly rounded upward from the respective left and right regions in a front view arc shape, and as a whole, has two curved surfaces continuous from the upper left to the lower right. It has a shape that extends while tilting down.

  The right side 153R of the decorative projecting body 153 extends from the lower end to the upper right while curving in a substantially arc shape along the right edge of the left side 153L, has a slightly narrow central part, and gradually increases upward and downward respectively. The shape bulges wide to the right. The peripheral wall 153P at the upper end portion of the right side portion 153R extends from the upper left end to the right lower side in a flat shape without being curved to constitute a receiving spherical wall 153C, while the lower end portion of the decorative projecting body 153 The peripheral wall 153P in FIG. 1 forms a curved surface as a whole while slightly indenting inward (upward) from the left lower end of the left side 153L to the right lower end of the right side 153R in a front view arc shape. It extends while tilting upward. The receiving surface wall 153C is connected to the right end of the upper end surface of the left side portion 153L and extends downward to the right, and guides the game ball flowing down by rolling on the upper end surface of the left side portion 153L. At the same time, however, the left ball receiving portion 149 is disposed and formed at a position immediately below the left, so in particular, the left ball receiving portion 149 is displaced to the left to enter the left winning port 148A. The ball receiving surface is often configured to receive the game ball that has flowed down and guide it to the lower right.

  As shown in FIGS. 60 to 62, the front wall 153K of the right side 153R of the decorative protrusion 153 is inclined so as to gradually recede inward (rearward) from the right side to the left side. It is formed so as to incline without being parallel to the board surface of the game board 30. That is, the right edge of the front wall 153K is positioned at the right front edge of the right part 153R, and the left edge of the front wall 153K is behind the left front edge of the right part 153R (slightly behind the center in the front-rear direction). Accordingly, the upper edge and the lower edge of the front wall 153K are, as shown in FIGS. 54 and 55, the upper surface wall of the right side portion 153R, that is, the receiving surface wall 153C and the lower surface wall 153U. On the other hand, they cross each other while inclining so as to gradually recede inward (rearward) from the right side to the left side. From the left side edge of the front wall 153K, it extends straight forward (front direction) to form the right side wall of the left side portion 153L. Therefore, as shown in FIGS. 60 to 62, the right side wall of the left side portion 153L, the front wall 153K and the right side wall of the right side portion 153R have a continuous shape while being bent in a substantially N-shaped cross section.

  Furthermore, the left side edge of the front wall 153K in the right side 153R of the decorative projecting body 153 recedes to a position slightly behind the center in the front-rear direction as described above at the upper end and the lower end, whereas in the height direction In the central part, it is retracted only to a position slightly ahead of the center in the front-rear direction. That is, the left side edge of the front wall 153K extends slightly curved so as to recede slightly shallowly in the center in the height direction and gradually recede deeply toward the upper and lower ends. In FIGS. 61 and 62, the left side edge of the front wall 153K extends so as to gradually recede from the center in the height direction to the lower end. In the figure, it gradually rises upward. Appears. With the above configuration, the front wall 153K of the right side portion 153R not only extends from the lower end to the upper right while curving in a substantially arc shape in front view, but also from the right center to the upper left end and the left left end, respectively. A curved surface that is slightly curved so as to gradually recede toward the inner back side is formed.

  On the front surface of the front wall 153K on the right side 153R of the decorative protrusion 153, as shown in FIG. 61, there is a decorative stamp 153G shaped like a character string that is lined up and down while curving along the curved surface shape described above. Is formed. Further, as shown in FIG. 59, a screw-in part 153D extending rearward in a cylindrical shape and having a screw hole inside is formed at the center of the upper end part on the rear surface (back surface) of the front wall 153K, and the left side part 153L. A similar threaded portion 153D extends along the inner side of the peripheral wall 153P at a position slightly inward (rightward) from the left end of the upper end edge on the inner surface (back surface) and a position slightly above the lower end of the left edge. Each is formed. The upper left and lower threaded portions 153D of these left side portions 153L are concealed from the front by the decorative projections 153S. Further, at the rear end edge (extended end edge) of the peripheral wall 153P, the position of the upper left end and the position of the lower left end of the right side portion 153R (that is, the position of the upper right end and the position of the lower right end of the left side portion 153L), Small protrusions 153E protruding rearward are formed at positions slightly inward (rightward) from the left end of the upper end edge (positions adjacent to the right side of the screw-in portion 153D) and positions near the left end of the lower end edge, respectively. The rear end edges of the upper wall portion and the lower wall portion of the peripheral wall 153P are respectively inserted into the grooves 151H of the first light diffusion member 151, and the small protrusions 153E correspond to the first light diffusion member 151 and the accessory base material. The projection insertion holes 151D and 148D of 148M are respectively inserted into the projection insertion holes 151D and 148D.

  The decorative projecting body 153 is disposed on the front surface of the accessory base material 148M from the front, and is fastened and fixed by screwing a screw into the screwing portion 153D through the screw insertion hole 148S.

  As shown in FIGS. 56 and 57, the back member 154 and the LED substrate 155 are arranged and fixed on the rear surface side of the accessory base material 148M. The back member 154 has an outer periphery that coincides with the entire outer periphery of the outer wall 148P of the accessory base material 148M except for the left winning collar portion 148K, and has a shape in which the peripheral wall extends slightly forward from the outer periphery. Screw insertion holes 154H are formed in the upper right corner, left lower end, and left central portion, respectively, and a rectangular opening 154T and upper and lower portions are formed in the upper center and lower center, respectively. A slightly long, generally rectangular connector insertion opening 154B is formed in each case.

  The LED substrate 155 has an outer shape substantially corresponding to the inner peripheral surface of the peripheral wall of the back member 154, and the upper right end portion extends in the width direction to a position adjacent to the left end of the upper right screw insertion hole 155H of the back member 154. The left lower end portion and the left central portion have a shape that is cut off or notched corresponding to the upper right screw insertion hole 155H of the back member 154. On the front surface of the LED substrate 155, LEDs 155D are respectively mounted at positions corresponding to the plurality (four) of light transmitting holes 148N of the accessory base material 148M.

  The LED board 155 is fitted inside the peripheral wall of the back member 154 and fastened and fixed by screws. The back member 154 has a front end edge of the peripheral wall at a rear end edge of the outer wall 148P of the accessory base material 148M. In such a manner, they are arranged so as to be fitted to the rear side of the accessory base material 148M from the rear, and are fastened and fixed to the threaded portion 148H of the accessory base material 148M with screws through the screw insertion holes 154H.

  The left decorative accessory 71L is fitted from the front into a through hole formed in the game board 30, and is fastened and fixed by a screw with a flange 148F. In the mounted state, the left winning bowl portion 148K extends rearward in the through hole of the game board 30 and communicates with the upper end of the left sphere passage 27L in the left sphere passage member 26L. The game ball that has entered the left ball receiving portion 149 of the object 71L flows into the upper end portion of the left ball passage 27L from the left winning ball receiving portion 148K and is detected by the left ball receiving sensor 29L. That is, the left prize receiving portion 149, the left prize winning port 148A, the left prize winning box 148K, the left ball path 27L in the left ball path member 26L, and the left ball entry sensor 29L constitute the general prize winning device 31A. It is configured.

  The right decorative accessory 71R is arranged and configured to be bilaterally symmetric with the left decorative accessory 71L. Therefore, the description of the right decorative accessory 71R is omitted.

(Function)
As described above, in the pachinko machine 10, as shown in FIG. 45 (a), the descending parts descending from the end side to the center side are formed on both sides, that is, the left half and the right half, respectively. The game ball M2 is rolled so as to reciprocate by its own weight, and between the two descending parts, the ball guide which guides the game ball M2 to be discharged to the side (that is, rearward in the pachinko machine 10) by its own weight. The ball passage 117 in which the portion 117E is formed has a configuration that is provided at a position visible from the outside. In the ball passage 117, the game ball M2 is moved in the traveling direction on the way to the discharge guide portion 117E. The left straight portion 118L and the right straight portion 118R, which are slack portions that can be passed with a margin in the width direction intersecting, and the margin in the width direction intersecting the game ball M2 in the traveling direction in the slack portion. Since the left corner portion 119L and the right corner portion 119R, which are the restriction portions that can be passed through with less, are formed in this order, the game ball M2 reciprocates between both descending portions of the ball passage 117 by its own weight. In the course of rolling, the left straight portion 118L first passes, but in the left straight portion 118L, which is a relaxation portion, the game ball M2 passes with a margin in the width direction intersecting the traveling direction. Therefore, the game ball M2 does not always pass along a fixed trajectory, but passes in a state where it can move somewhat, that is, in a state where it can be freely displaced by a margin in the width direction. Unexpected nature is given to the behavior of the game ball M2, and interest is secured. After passing through the left straight portion 118L, the game ball M2 passes through the left corner portion 119L as a restricting portion. At this time, for example, as shown in FIG. 45 (b), a restricting portion is formed. Therefore, if the path of the game ball M3 remains unrestricted by the restricting portion, the game ball M3 rolls freely in the width direction as described above, so that the ball path is thereafter Although it cannot be predicted in which direction in 156 this will be exciting, it can be said that the excitement is excited in this respect. However, there is a great possibility that the excitement will be immediately cut off from the ball guide unit 156E. However, according to the ball passage 117 in the pachinko machine 10, the left corner portion 119L, which is a restricting portion, has a small margin in the width direction that intersects the traveling direction of the game ball, so the path of the game ball M2 is reciprocated by the restricting portion. Therefore, the ball is not immediately discharged from the ball discharge guide portion 117E to the side as in the case of the above-described ball passage 156 in which no restriction portion is formed. The house will go back and forth through the ball escape guide 117E. Thereafter, the momentum of the game ball M2 is attenuated as it is reciprocated, and when the momentum becomes weak enough that it cannot pass through the ball discharge guide portion 117E, the game ball M2 is guided to the ball discharge guide portion 117E by its own weight. Is discharged to the side. Thus, while the game ball M2 has a certain momentum or more, the left corner portion 119L and the right corner portion 119R that are the restriction portions pass through the ball discharge guide portion 117E without departing from the reciprocating orbit. It is controlled to reciprocate, so that it can roll longer on the ball path 117.

  Further, since the restricting portion is formed by narrowing the movable width of the ball passage 117 in the left corner portion 119L and the right corner portion 119R, the path of the game ball M2 is effectively restricted with a simple configuration. It is a regulatory part to get.

Further, since the spherical passage 117 has a left corner portion 119L and a right corner portion 119R and is formed to have a curved shape in plan view, for example, a spherical passage formed to have a straight shape in plan view. Compared to the case, not only the change of the trajectory of the game ball M2 is given and the effect effect is good, but also the unexpected behavior is given to the behavior of the game ball M2 to ensure the interest. On the other hand, if there is no restriction part, the inconvenience that the game ball M2 is immediately discharged from the discharge ball guide part 156E to the side is more likely to occur, so that the effect by the formation of the restriction part is further exhibited. Yes.
Furthermore, it is possible to roll the game ball M2 along the outer guide rail by utilizing the centrifugal force due to the curved shape of the left corner portion 119L and the right corner portion 119R, thereby further reliably and effectively. The path of the game ball M2 can be restricted on the reciprocating path.

  Further, above the ball passage 117, there are portions extending in the lateral direction at the upper and lower portions, that is, a horizontal portion 115C and a retreat portion 115B, and the game ball M2 is drawn from the upper end of the ball passage 117 from above. That is, since the ball guide passage, ie, the guide tube portion 115, is guided to the guide slope 117S at the left rear end, the ball passage is arranged so that the game ball M2 flows down over time while being guided in multiple directions. It is guided to 117, and this makes the entertainment last longer.

  Further, since the ball guide passage, that is, the ball guide tube portion 115 is made of a light-transmitting resin, the game ball M2 flowing down in the ball guide tube portion 115 is visually recognized and visually. A production effect can be obtained.

  The ball passage 117 has guide rails 117F and 117R along both sides, and the ball discharge guide portion 117E is spaced from one of the guide rails 117F and 117R on both sides, that is, the guide rail 117R on the rear side. Since an opening part that is partially opened is formed by opening the ball path 117 and the ball passage 117 is inclined downward to the opening part side (rear side), the game ball M2 has a certain level or more. While maintaining momentum, the game ball M2 can easily pass through, and when the momentum of the game ball M2 is attenuated to a certain extent, the game ball M2 can be guided to reliably discharge the game ball M2 to the side by its own weight. The guide part 117E is formed with a simple configuration.

  In addition, a lower prize winning mechanism is provided that distributes the game ball M2 discharged from the discharge guide part 117E into a game area advantageous to the player and a game area less advantageous than the game area, and is regulated by the regulation unit. Since the second magnetic sensor 57 and the vibration sensor 70 are provided as fraud detection means for detecting an illegal operation on the behavior of the game ball M2 during or after being restricted, it is possible to effectively detect fraud. Can do. In particular, when the winning mechanism is arranged so as to communicate with the ball passage 117 as described above, the game ball M2 is illegally manipulated during or after circulation in the ball passage 117, and the game is performed. As described above, the pachinko machine 10 is configured such that the gaming ball M2 can roll longer in the ball path 117 as described above. It is easier to add illegal operations. In addition, since the game ball M2 is regulated by the regulation unit so as to circulate on a certain trajectory, an unauthorized operation is more easily applied. Therefore, it is effective to provide fraud detection means for detecting an illegal operation with respect to the behavior of the game ball M2 while being regulated by the regulation unit as described above or after being regulated.

  Further, as the fraud detection means, the second magnetic sensor 57 is arranged toward the vicinity of the ball discharge guide portion 117E. Therefore, the game ball M2 is illegally guided from the vicinity of the ball discharge guide portion 117E by a magnet, and the lower stage. It is possible to effectively detect an unauthorized operation to be awarded by the winning mechanism. In the case of such an unauthorized operation with a magnet, the game ball M2 is guided to the vicinity of the ball discharging guide portion 117E by the magnet, so that it is particularly effective to set the vicinity of the ball discharging guide portion 117E within the detection range. .

  Further, the pachinko machine 10 includes a game board 30 that causes a game ball to flow down on the front surface, and a right decoration accessory 71R and a left decoration accessory on the front surface of the game board 30 as an accessory for guiding the game ball in a predetermined direction. In a configuration in which 71L is arranged, a winning ball (left winning port 148A in the case of the left decorative member 71L) is formed integrally with the right decorative member 71R and the left decorative member 71L, and the game ball that has flowed down. Receiving surface wall 153C is formed, and front surface wall 153K that intersects the receiving surface wall 153C in an inclined posture without being parallel to the surface of the game board 30 is formed. Thus, both the mechanical strength and the decorativeness of the right decorative accessory 71R and the left decorative accessory 71L can be improved. The right decorative accessory 71R and the left decorative accessory 71L have a winning opening formed integrally therewith so that game balls flow down particularly frequently. When the ball receiving surface is arranged on 71L, it is natural that the game balls that flow down are directly received and are easily damaged. Therefore, by forming the front wall 153K that intersects the receiving spherical wall 153C while inclining as described above, the front wall 153K functions as a reinforcing rib of the receiving spherical wall 153C. The mechanical strength is effectively improved. Further, since the front wall 153K is inclined with respect to the board surface of the game board 30, a three-dimensional effect is imparted to the front wall 153K and the decorativeness is improved. In other words, both the mechanical strength of the receiving surface wall 153C and the decorativeness of the front wall 153K are effectively improved by the simple configuration of forming the front wall 153K that intersects with the inclined posture with respect to the receiving surface wall 153C. ing.

  Further, the right decorative accessory 71R and the left decorative accessory 71L are the upper part of the game area where the game ball flows down (that is, the position from the left end to the upper left end and the position from the right end to the upper right end in the game area). It is particularly effective because it is arranged at a position where the game ball can be abutted vigorously. The purpose of avoiding damage to the right decorative accessory 71R and the left decorative accessory 71L by arranging the right decorative accessory 71R and the left decorative accessory 71L with the receiving spherical wall 153C at a position where the game ball can vigorously abut. Then, a nail for protecting the right decorative accessory 71R and the left decorative accessory 71L is provided around the right decorative accessory 71R and the left decorative accessory 71L, or a member using rubber or elastomer as a cushioning material is provided. The cost of the pachinko machine 10 as a whole is reduced and the placement position and size of the right decorative accessory 71R and the left decorative accessory 71L having a winning opening into which a game ball can enter are reduced. The degree of design freedom is high.

  In addition, the spherical surface wall 153C is disposed on the downstream side of the winning opening so as to be able to hit a game ball that has not entered the winning opening. Since the game ball often flows down without entering the winning opening on the downstream side of the winning opening, as described above, the front wall 153K that intersects with the receiving spherical wall 153C is formed. Such a configuration is more effective.

  Further, since the front wall 153K is a curved surface that curves in the front-rear direction, the decorative property of the front wall 153K is better.

  In addition, the upper end portion communicates with the winning opening of the right decorative accessory 71R or the left decorative accessory 71L, and the lower end portion communicates with a drainage passage of another member disposed below to enter the winning opening. Since the right sphere passage member 26R or the left sphere passage member 26L having the right sphere passage 27R or the left sphere passage 27L for guiding the game ball to the lower discharge passage is arranged on the back side of the game board 30, the right decoration The upstream portion of the passage for discharging the game ball that has entered the winning opening of the object 71R or the left decorative accessory 71L is partially constituted by the right ball passage member 26R or the left ball passage member 26L. For example, even when the configuration and arrangement of the right decorative accessory 71R and the left decorative accessory 71L are changed to different ones according to the model change, the right decorative accessory 71R and the left decorative accessory There is no need to change the entire game ball discharge passage communicating with the 1L winning opening, and only a part of the right ball passage member 26R or the left ball passage member 26L can be handled by replacing it with another one. Alternatively, the right sphere passage member 26R or the left sphere passage member 26L may be omitted, and a larger liquid crystal display device may be arranged using the space, or another member different from the sphere passage member. Can also be arranged. For example, if the entire path for discharging game balls is formed on the ball assembly plate, it is necessary to change the ball assembly plate. In particular, the ball assembly plate includes a plurality of passages including other passages. Therefore, it is easy to change a passage that does not need to be changed. On the other hand, in the pachinko machine 10, the upstream portion of the game ball discharge passage is configured separately and independently as the right ball passage member 26R or the left ball passage member 26L as described above. Only the part can be changed partially, so that the range of change is minimized.

  In addition, opening and closing blades 89R and 89L are disposed on the front surface of the game board 30 so as to move between a closed position where a game ball is difficult to enter or cannot enter and an open position where the game ball is easy to enter. Since the right decorative accessory 71R or the left decorative accessory 71L is disposed on the side of the opening / closing blades 89R and 89L, the winning opening of the right decorative accessory 71R or the left decorative accessory 71L as described above. A configuration in which the upstream portion of the game ball discharge passage communicating with the right ball passage member 26R or the left ball passage member 26L is made independent is more effective. Since the opening and closing blades 89R and 89L are particularly noticeable in terms of whether or not a game ball enters, the arrangement configuration in the vicinity thereof is highly important and can be easily changed. 71R or the left decorative accessory 71L is also easily changed because it is arranged on the side of the opening and closing blades 89R and 89L. Therefore, as described above, the upstream portion of the game ball discharge passage is separately and independently provided. It is useful to configure.

  Further, a back cover member 82 is attached to the back side of the game board 30 so as to cover the back side of the game board 30, and the right sphere passage member 26 </ b> R to the left sphere passage member 26 </ b> L are disposed in front of the back cover member 82. Since the right side ball passage member 26R to the left side ball passage member 26L can be easily arranged and fixed on the back side of the game board 30 because they are arranged and fixed on the side surfaces. As described above, the upstream portion of the game ball discharge passage communicating with the winning opening of the right decorative accessory 71R or the left decorative accessory 71L is configured as the right spherical passage member 26R or the left spherical passage member 26L separately and independently. In this case, if the right sphere passage member 26R or the left sphere passage member 26L is arranged and fixed directly on the back surface side of the game board 30, the mounting work is troublesome. If the member 26R or the left sphere passage member 26L is arranged and fixed on the front side surface of the back cover member 82, the right sphere passage member 26R or the left sphere passage member 26L together with the back cover member 82 at once is the game board 30. Since the right side ball passage member 26R or the left side ball passage member 26L does not need to be individually attached to the back side of the game board 30, the positioning can be performed. Needed next, thus the mounting operation can be easily performed.

(Modification)
The pachinko machine 10 can be variously modified as listed below, for example.

(1) In the above embodiment, the restricting portion of the ball passage 117 is formed by narrowing the movable width of the ball passage 117, but the restricting portion can restrict the course of the game ball. For example, as shown in FIG. 63, the bottom surface of the ball passage 158 is formed so as to be inclined downward from one side to the other side so that the game ball M4 is brought close to the guide rail 158F on the other side. It is good also as a structure to let it pass. In the example shown in the figure, since the bottom surface of the ball passage 158 is inclined downward from one side to the other side, the game ball M4 comes into contact with the guide rail 158F on the other side in the ball passage 158, thereby It passes through while being regulated at the position closest to the other side (the other side limit position) where the outward movement is regulated. That is, the game ball M4 passes while being regulated so as to roll on a substantially single trajectory passing through the other side limit position, with the movement to the outside and the inside inward being restricted from the other side limit position. In this case, the movable width coincides with the diameter of the game ball M4, that is, the game ball M4 is regulated so as not to move in the width direction from the limit position on the other side. . In this configuration, the path of the game ball M4 is restricted by the inclination of the bottom surface of the ball passage 158 and the guide rail 158F on the other side, so that the restricting portion is configured regardless of the width of the ball passage 158. .

  Alternatively, for example, as shown in FIG. 64, the bottom surface of the ball passage 159 may be formed so as to be inclined downward from both sides toward the center, and the game ball M5 may be passed toward the center. In the example shown in the figure, the bottom surface of the ball passage 159 is inclined downward from both sides toward the center so that the game ball M5 passes through the ball passage 159 while being regulated at the center in the width direction. It has become. That is, the game ball M5 is controlled so as to roll on a substantially single trajectory passing through the center position in the width direction, while being moved outward and inward from the center position in the width direction. In this case, the movable width coincides with the diameter of the game ball M5, that is, the game ball M5 is regulated so as not to move in the width direction from the center in the width direction. ing. In this configuration, since the path of the game ball M5 is restricted by the inclination of the bottom surface of the ball passage 159, the restriction portion is configured regardless of the width of the ball passage 159.

  Alternatively, for example, when the height of the guide rail in the ball passage is less than the radius (about 5.5 mm) of the game ball, the restricting portion can also be configured by forming the guide rail partially higher. it can. When the height of the guide rail is less than the radius of the game ball (about 5.5 mm), the movable width becomes narrower as the guide rail becomes higher.

(2) In the above-described embodiment, the first magnetic sensor 114 and the second magnetic sensor 57, which are fraud detection means, are connected to the ball passage 127R of the ball guide 127 and the ball guide part 117E of the stage member 88 in the upper stage unit 86. They were placed with their tips facing each other (vertically placed), but in addition to this, malfunctions may occur between magnetic sensors or other winning sensors if there is a possibility of unauthorized operation. Unless it is a position where it can occur, it is desirable to arrange the magnetic sensor as much as possible. FIG. 65 is a diagram showing an example in which the third magnetic sensors 22R and 22L are arranged and fixed inside the both side walls of the outer member 122 of the center accessory 83 in the embodiment. The left and right third magnetic sensors 22R, 22L shown in the figure have the same configuration as the first magnetic sensor 114, and particularly the left and right open / close blades 89R of the upper left incoming ball portion 92L and the upper right incoming ball portion 92R, It is arranged (vertically placed) near the shaft support position of 89L so that the shaft support positions of the opening and closing blades 89R and 89L and the vicinity thereof are within the detection range. The opening and closing blades 89R and 89L and the positions in the vicinity of the opening and closing blades 89R and 89L are also one of the places where it is easy to perform an illegal operation to guide the game ball to enter with a magnet, and it is desirable to arrange the magnetic sensor as described above. One.

(3) In the above embodiment, as the fraud detection means, in addition to the first and second magnetic sensors 114 and 57, the fraudulent act of manipulating the behavior of the game ball by shaking or hitting the game machine. Although the vibration sensor 70 to detect is provided, as the fraud detection means, other than this, for example, an infrared sensor, an ultrasonic sensor, a laser sensor, a radar sensor for detecting an object such as an appliance that has illegally entered a gaming machine Etc., or a plurality of the above various sensors may be arranged together.

(4) In the above-described embodiment, the front wall 153K intersects the receiving wall 153C of the right decorative accessory 71R and the left decorative accessory 71L with a posture in which the front wall 153K is inclined, and is a straight line that is inclined with respect to the board surface of the game board 30 The crossing line is an oblique line, but the crossing line between the receiving surface wall 161 and the front wall 162 is bent in a mountain shape, for example, as in the left decorative accessory 160L shown in FIG. Or may be bent in various shapes such as a valley shape, a zigzag shape, a wave shape, and an arc shape (not shown).

  This specification discloses all of the following inventions.

The gaming machine according to the present invention has as means 1,
Lowering parts that descend from the end side to the center side are formed on both sides, respectively, so that the game balls roll between the lowering parts so as to reciprocate by their own weight, and the game balls are A game machine in which a ball passage formed with a ball discharge guide for guiding the ball to be discharged to the side by its own weight is provided at a position where it can be seen from the outside,
In the ball path, on the way to the ball discharging guide part, a loosening part that allows the game ball to pass with a margin in the width direction intersecting the traveling direction and a width direction intersecting the game ball in the traveling direction. It is characterized in that a restricting portion that allows passage with less margin than in the relaxed portion is formed in this order.

  In the present invention, the “side” when the game ball is discharged by its own weight in the ball discharge guide is the side with respect to the distribution direction of the game ball in the ball passage, and the side in the gaming machine is not necessarily It does not match.

  According to the configuration of the means 1, the game ball first passes through the relaxing part while rolling so that the game ball reciprocates between both descending parts of the ball passage by its own weight. In this relaxing part, Since the game ball passes with a margin in the width direction intersecting the traveling direction, the game ball does not always pass on a fixed trajectory, but can be moved somewhat, that is, with a margin in the width direction. It will pass in a state where it can be shifted, so that unexpected behavior is given to the behavior of the game ball, and interest is secured. After passing through the relaxation portion, the game ball passes through the restricting portion. At this time, for example, if the course of the game ball remains unregulated by the restricting portion, the game ball is as described above. Since it rolls freely in the width direction so that it can move freely, it can not be predicted in which direction in the ball passage after this, and it can be said that the excitement will be excited at this point, but immediately from the ball guide part to the side There is also a high possibility that the excitement will be cut off. However, according to the configuration of the means 1, the regulating portion has a small margin in the width direction that intersects the advancing direction of the game ball, and therefore, the path of the game ball is regulated so that it does not deviate from the reciprocating orbit. As described above, the ball is not immediately discharged from the ball guide part to the side, and at first, the ball passes through the ball guide part and reciprocates. After that, the momentum of the game ball attenuates as the round trip is repeated, so if the momentum weakens to such an extent that it cannot sufficiently pass through the ball discharge guide part, the game ball is guided to the ball discharge guide part by its own weight and moved sideways. Discharged. In this way, while the game ball has a certain momentum or more, it is controlled by the restricting portion so as to reciprocate through the discharge guide portion without deviating from the reciprocating orbit, and therefore on the ball path. It will be possible to roll longer.

The gaming machine according to the present invention is a gaming machine of means 1 as means 2,
The restricting portion is formed by narrowing a movable width of the spherical passage.

  In the present invention, the “movable width of the ball passage” means a range in which the game ball can move in the width direction in the ball passage. For example, in the case of a ball passage having guide rails on both sides, The position closest to one side where contact with the guide rail on one side in the passage is restricted and the outward movement is restricted (hereinafter also referred to as “one-side limit position”), and the game ball in the other side in the ball passage The width of the range with both ends at the position closest to the other side (hereinafter also referred to as “the other side limit position”) that contacts the side guide rail and is restricted from moving outward is equivalent to this movable width. To do. For example, when the height of the guide rails on both sides is equal to or larger than the radius of the game ball (about 5.5 mm), the game ball is brought into contact with the inner surface of the guide rail at one side limit position or the other side limit position. The outward movement is restricted, and in this case, the movable width coincides with the width of the spherical passage (that is, the distance between the two guide rails). On the other hand, as shown in FIGS. 21 to 22, for example, when the height of the guide rails 117F and 117R on both sides is less than the radius (D1 × 1/2) of the game ball M1 = about 5.5 mm, the game ball M1 Is abutted against the upper ends of the guide rails 117F and 117R at one limit position or the other limit position, and the outward movement of the guide rails 117F and 117R is restricted. Accordingly, the movable widths F1 and F2 are accordingly larger than the width of the spherical passage (that is, the distance between the guide rails 117F and 117R) W1 and W2.

  According to the configuration of the means 2, it is possible to form a restricting portion that can effectively restrict the course of the game ball with a simple configuration.

Further, the gaming machine according to the present invention is a gaming machine of means 1 or means 2 as means 3,
The spherical passage is formed to have a curved shape in plan view.

The “winning entrance” is a winning entrance where a certain prize ball is paid out when a game ball enters, or a predetermined lottery when a game ball enters and a prize is won. It may be a winning opening that makes it easy for a game ball to be acquired when the opening of the game is opened. In such a case, when a gaming ball wins a winning opening, In addition to a payout, a prize ball may not be paid out.

  According to the configuration of the means 9, the mechanical strength and decorativeness of the accessory can be improved with a simple configuration. When the winning hole is formed integrally with the accessory, the game ball flows down particularly frequently. Therefore, when the receiving surface is arranged on the accessory, the game ball flowing down is directly received. Of course, it becomes easy to break. Accordingly, by forming a front wall that intersects the receiving spherical wall while being inclined with respect to the configuration of the means 9, the front wall functions as a reinforcing rib for the receiving spherical wall. Effective strength can be improved effectively. Further, by inclining the front wall with respect to the board surface of the game board, it is possible to give the front wall a three-dimensional effect and to improve the decorativeness. In other words, both the mechanical strength of the receiving surface wall and the decorativeness of the front wall can be effectively improved by a simple configuration in which the front wall intersecting with the inclined posture with respect to the receiving surface wall is formed.

  Further, the accessory of the means 9 is provided in the upper part of the game area where the game ball flows down, or before the moment of the game ball that has entered the game area after the game ball is released, that is, far from the entrance of the game area. This is particularly effective when a part of an accessory is arranged at a position where the game ball can be abutted vigorously, such as when the game ball is provided at a position where the game ball abuts the game ball. By placing an accessory with a receiving spherical wall at a position where the game ball can vigorously abut, a nail protecting the accessory is provided around the accessory for the purpose of avoiding damage to the accessory, or as a cushioning material While reducing the cost of the entire gaming machine by reducing the need to provide rubber or elastomeric members, etc., the placement position and size of an accessory that has a winning opening that allows game balls to enter The degree of design freedom can be increased.
