Description

  The present invention relates to a ball game machine such as a pachinko machine installed and used in a game arcade.

  In the present specification, a pachinko machine is described as an example of a ball game machine, and therefore, a pachinko ball is used as a game ball. However, the game ball includes other spherical media. In addition, it is assumed that a pachinko ball enters a winning opening provided on the game board.

  A pachinko machine used in a game hall such as a pachinko parlor is given a certain value to a pachinko ball, and the pachinko ball acquired by playing a game can be exchanged for various prizes. For this reason, the main purpose of the player is to acquire a large amount of pachinko balls, and it is one of the pleasures to play a game in a game mode in which a large amount of pachinko balls can be acquired in a short period of time.

  As a kind of pachinko machine, a kind of pachinko machine called a digipachi type is known. Some digital-pachinko-type pachinko machines are set with three game modes: a normal mode, a hit mode, and a probability variation mode. In such a pachinko machine, when a pachinko ball wins the start winning opening in a game in the normal mode, the symbol variation display device provided on the game board displays the symbol variation display and the stop display, and the winning decision lottery is performed. Is called. Then, the result of the winning determination lottery is notified to the player by the stop display of the symbol that is variably displayed. In the hit determination lottery, either a probability change for granting the right to shift to the probability variation mode, a hit for granting the right to shift to the hit mode, or a loss that does not grant any right is determined.

  In the winning mode, the attacker (movable door) rotates, and the large winning opening closed in the normal mode is repeatedly opened up to a predetermined number of times. The winning mode ends when the special winning opening is opened a predetermined number of times. One opening of the grand prize opening, that is, one round is continued until, for example, the grand prize opening is opened for 30 seconds or ten pachinko balls are won in the big prize opening. When the winning mode is entered, the large winning opening that is closed in the normal mode is opened, so that it is easier to acquire a pachinko ball than in the normal mode.

  Further, the probability variation mode is shifted to a predetermined game period following the hit mode. In the probability variation mode, the winning probability per hit or probability change is higher than in the normal mode, and when transitioning to the probability variation mode, the number of games before transitioning to the hit mode again tends to be shorter than in the normal mode. . For this reason, it is almost the case that a player plays a game while having a sense of expectation for winning by chance rather than winning.

  By the way, in most models of the digital pachislot type pachinko machines, a center accessory is provided on the front surface of the game board so as to surround the symbol variation display device. In general, the center role is provided with a stage for temporarily receiving the hit pachinko ball. Part or all of the stage is inclined toward the start winning opening, and the pachinko balls that have fallen on the stage can easily win the starting winning opening. In addition, depending on the type of the center accessory, there is a ball path that guides a pachinko ball that has entered the ball entrance formed on the outer peripheral surface to a ball exit formed separately from the ball entrance. In such a center role, the ball exit is arranged so that the pachinko ball from the ball exit comes out on the stage, and the pachinko ball that has passed through the ball passage becomes easy to win the starting prize opening. Whether or not the ball enters the ball entrance is one of the players' concerns. Thereby, interest can be attracted to the movement of a pachinko ball, and tension when playing a game can be enhanced.

  However, in the pachinko machine as described above, there is only a single path through which the pachinko ball passes through the ball passage, and the pachinko ball that has entered the ball entrance is merely guided to the stage. The person was interested in the movement of the pachinko ball that came out of the ball exit, but was not interested in the movement of the pachinko ball in the ball passage.

  An object of the present invention is to provide a ball game machine capable of attracting interest in the movement of a pachinko ball passing through a ball path of a center accessory.

  FIG. 1 shows an external appearance of the pachinko machine 10, and first, an outline of a game flow of the pachinko machine 10 will be described. The pachinko machine 10 is provided with three game modes: a normal mode, a hit mode, and a time reduction mode (a game state that is advantageous for a player to acquire a game ball). When a pachinko ball wins a start winning opening 15 which will be described later, a winning determination lottery for determining whether or not to win is made by a lottery, and when a win is made in the winning determination lottery, the normal mode is changed to the winning mode. In the winning mode, a later-described special winning opening that is closed in the normal mode is opened. In the single hit mode, the number of times of opening the grand prize opening is set to 15 times, and for example, 30 seconds have elapsed per opening of the big prize opening, or it is set to continue to be released until 10 pachinko balls are won. . In the time reduction mode, the time from the start of the symbol change display to the stop display of the symbol is shorter than in the normal mode, and as will be described in detail later, the pachinko ball wins in the start winning opening 15 than in the normal mode. It becomes easy to do.

  The pachinko machine 10 includes a main unit 11, a game board unit 12, and a glass frame 13. The main unit 11 is provided with devices such as a pachinko ball launching device, a prize ball payout device, a power supply circuit, a lamp, a speaker and the like that are operated according to the gaming state.

  The game board unit 12 includes a game board 12a. In the game area on the front side of the game board 12a, a symbol display device (symbol variation display device) 14, a start winning port 15, a normal winning port 16, an attacker 17, an out port 18, and a center accessory 19 are provided. In addition, although illustration is abbreviate | omitted, in the game area | region of the game board 12a, several obstacle nails, a windmill, etc. are provided in the suitable place.

  When the operation handle 20 is operated, the pachinko balls are shot one by one into the game area of the game board 12 by the pachinko ball launching device, and enter the start winning port 15, the normal winning port 16, the passing winning port 17, or the out port 18. . When a pachinko ball enters the start winning opening 15, the symbol display device 14 is operated, and the displayed symbol variation display and stop display are performed to notify the result of the winning lottery and effect processing. Then, when the symbol combination when the symbol stop display is performed becomes a predetermined combination, the winning combination is made and the mode is changed to the winning mode. Note that the display area of the symbol display device 14 is divided into a display region for performing variable display and stop display of a symbol and a region for displaying a result of a winning advantageous lottery to be described later. Is also displayed.

  The start winning opening 15 is provided with a pair of movable members 15a so as to face each other. The movable member 15a is located between a closed position where the movable members 15a face each other and an open position where the tip of the movable member 15a rotates so as to move away from each other and the area where the pachinko ball wins the start winning opening 15 is wider than the closed position. It is pivotally attached. The movable member 15a is rotated to the open position when the winning advantage lottery for determining whether or not the movable member 15a is rotated to the open position is won. The movable member 15a is held at the open position for 0.5 seconds per opening in the normal mode, but is held at the open position for 2 seconds per time in the time reduction mode. As a result, in the short time mode, the pachinko ball is more likely to win the start winning opening 15 than in the normal mode. Note that the pitch between the movable members 15a is set so that a pachinko ball can be won even when the movable member 15a is in the closed position.

  When a pachinko ball wins a prize winning opening 15, a normal winning opening 16, or a large winning opening at the back of the attacker 17, the number of winning balls corresponding to the type of the winning opening is paid out from the payout opening 22 to the ball receiving tray 23. On the other hand, when the pachinko ball does not win the start winning port 15, the normal winning port 16 or the attacker 17, the unpaid pachinko ball enters the out port 18 and is collected as a lost ball.

  A lamp (notification device) 23 is provided on the upper part of the front surface of the glass frame 13. The lamp 23 is normally turned off, and is turned on when a pachinko ball passes through a passage gate 57 described later.

  As shown in FIGS. 2 and 3, the center accessory 19 is provided with an opening 30 that exposes the symbol display device 14, a stage 31 that temporarily receives a pachinko ball, an upper sphere passage member 32, and a spiral sphere passage member 33. It has been.

  The center accessory 19 is formed in a frame shape, and when the center accessory 19 is attached to the game board 12a, the symbol display device 14 is exposed from the opening 30. The stage 31 is curved so that its upper surface gradually becomes higher from the center to both ends. As a result, the pachinko balls that have fallen on both ends of the stage 31 are gathered at the center. Further, the stage 31 is inclined toward the front side of the game board 12a, and the pachinko ball on the stage 31 falls to the front side of the game board 12a by its own weight.

  In the stage 31, a stage ball inlet 31a is formed on the upper surface and a stage ball outlet 31b is formed on the front surface, and a passage communicating with the stage ball inlet 31a and the stage ball outlet 31b is formed inside the stage 31. Has been. When the pachinko ball enters the stage ball inlet 31a, the pachinko ball passes through the internal passage and is discharged from the stage ball outlet 31b. The stage ball outlet 31b is disposed above the start winning opening 15, and the pachinko ball discharged from the stage ball outlet 31b has a higher probability of winning the start winning opening 15. A ball entrance 34 into which a pachinko ball enters is formed on the outer periphery of the center accessory 19. The pachinko ball that has entered the ball inlet 34 falls into the upper ball passage member 32.

  As shown in FIG. 4, the upper sphere passage member 32 includes a base member 40 and a passage see-through member 41. The base member 40 is formed in a box shape with an open top. The pachinko ball that has entered the ball inlet 34 falls on the base member 40. As shown in FIG. 5, the base member 40 is formed with a basic passage 43 that communicates with the ball inlet 34 and the ball outlet 42 and guides the pachinko ball that has entered the ball inlet 34 to the ball outlet 42. Further, the base member 40 is formed with a branch passage 44 that branches from the main passage 43 and causes the pachinko balls to flow down along a different path from the main passage 43 and then joins the pachinko balls to the main passage 43 again. . As shown in FIG. 6, the main passage 43 and the branch passage 44 are inclined so that pachinko balls can flow down to the ball outlet 35 under their own weight. Then, the route B flows down by its own weight.

  Further, a step 46 a is provided at a branch portion on the upstream side of the main passage 43 and the branch passage 44 so that the branch passage 44 is one step lower than the main passage 43. Furthermore, a step 46 b is provided at the junction portion downstream of the main passage 43 and the branch passage 44 so that the main passage 43 is one step lower than the branch passage 44. For this reason, when the pachinko balls flow down from the main passage 43 to the branch passage 44 and when the branch passage 44 joins the main passage 43, the flow of the pachinko balls stops and the pachinko balls are prevented from clogging in each passage. ing.

  A U-shaped passage gate 47 is provided at a portion of the branch passage 44 where the pachinko ball goes straight. The passage gate 47 includes a passage gate sensor 58 to be described later. When the pachinko sphere passes between both legs of the passage gate 47, the pachinko sphere is detected.

  The passage see-through member 41 is disposed between the main passage 43 and the branch passage 44. The passage see-through member 41 is formed in a rectangular parallelepiped shape with a transparent resin, and the front surface is a transparent window 41a. Thereby, since it becomes possible to visually recognize the branch passage 44 from the front side of the game board 12a, the pachinko ball that has passed through the passing gate 47 can be visually recognized. Further, the upper spherical passage member 32 is provided with a lamp 32 a so as to be positioned below the passage see-through member 41. The lamp 32a is turned on when a pachinko ball passes through the passage gate 47.

  A ball guiding member 48 is provided on the upstream side of the main passage 43. The ball guide member 48 protrudes upward from the main passage 43 and cannot flow down from the main passage 43 to the branch passage 44. The ball guide member 48 retreats from the main passage 43 and branches from the main passage 43. The pachinko ball can move between a flowable position and a flowable position where the pachinko ball can flow down. The ball guiding member 48 is positioned at a position where it can flow down in the normal mode, and is controlled to be positioned at a position where it cannot flow down in the time reduction mode.

  The spiral sphere passage member 33 is disposed adjacent to the upper sphere passage member 32 and the stage 31. Then, the pachinko balls from the ball outlet 42 flow down into the spiral ball passage member 33 from the ball inlet 33 a of the spiral ball passage member 33. The spiral sphere passage member 33 includes a spiral sphere passage 33b therein, and the pachinko balls that have flowed down the ball passage 33b flow down to the stage 31 from the ball outlet 33c.

  As shown in FIG. 7, the operation of the pachinko machine 10 is controlled by a main control unit 50 and a sub control unit 51. The main controller 50 is provided with a main controller 52. The pachinko machine 10 is controlled by a CPU (game execution control means) 53 provided in the main controller 52.

  In addition to the CPU 53, the main control device 52 is provided with a memory 54, a hit determination unit 55, a stop symbol determination unit 56, and a winning advantage lottery unit 57. The CPU 53 controls the operation of the pachinko machine 10 in accordance with a program stored in the ROM area of the memory 54 to execute a game.

  The winning determination unit 55 includes a random number generator, a random number sampling circuit, and a winning determination table for determining whether or not to win, and samples a random value every time a winning of a pachinko ball wins at the start winning opening 15. The sampled random number value is checked against a hit determination table, and whether or not to shift to the hit mode is determined by lottery.

  In the winning determination table, a random value to be a winning is assigned among all random values generated when sampling of random values. Then, by determining whether or not the sampled random number value matches the random value assigned to the hit determination table, it is determined whether to be lost or hit. In the present embodiment, the winning type is set to one type. For example, as in the present embodiment, the winning type is shifted to the winning mode only, and during the fixed game period after the winning mode ends, the normal mode is changed. The winning type may be set as appropriate, for example, a probability change mode in which the probability of winning a win is increased. In addition, for example, in the hit determination table, all random numbers generated when sampling random values are divided into two numerical ranges in advance, and in the hit determination table, lost and hit are assigned to the respective numerical ranges, and sampling is performed. It may be determined by an appropriate method, for example, determining a winning or losing according to which numerical value range the assigned random number value belongs to.

  The stop symbol determination unit 56 determines a combination of symbols to be stopped by the symbol display device 14. The stop symbol determination unit 56 includes a random number generator, a random number sampling circuit, and a stop symbol table, and is operated after the winning determination unit 55 performs a lottery. The stop symbol table is composed of two types of tables: a lose table and a winning table. Which table is used for the lottery is selected based on the lottery result in the hit determination unit 55. Then, when the random number values sampled by the random number sampling circuit are compared with the selected table, a combination of symbols to be stopped on the winning line is determined. When the lottery at the stop symbol determination unit 56 is completed and the combination of symbols to be stopped on the winning pay line is determined, a signal indicating the combination of symbols determined from the CPU 53 is input to the symbol display control device 59 described later. The

  The winning advantage lottery section 57 is activated when a pachinko ball passes through the passing gate 57. In the prize-winning lottery unit 57, a prize-winning lottery for determining whether or not the movable member 15a is rotated from the closed position to the open position is performed.

  The CPU 53 receives a signal from the passage gate sensor 58 and transmits various signals to the symbol display control device 59, the lamp control device 60, the payout control device 61, and the movable member control device 62. In addition, a launch control device 63 is provided in the main control unit 30.

  The symbol display control device 59 includes a CPU and a memory. The CPU reads out display data in the memory, and causes the symbol display device 14 to perform symbol variation display and stop display. The CPU monitors the head address assigned to each symbol displayed from the symbol display device 14 to identify which symbol is variably displayed, and the symbol of the type determined by the stop symbol determining unit 56 Stop displaying symbols so that they are displayed. The display data stored in the memory also includes display data for displaying whether or not the winning advantageous lottery has been won. When the winning advantageous lottery is performed, this is read and the result is read out. Is displayed.

  The lamp control device 60 includes a CPU and a memory, and data for controlling the lighting of the lamp is stored in the memory. The lamp controller 60 is activated by the CPU 53 when a pachinko ball is detected by the passing gate sensor 58. The CPU turns on the lamp 23 and the lamp 32a for a predetermined time by reading the data in the memory.

  The payout control device 61 is activated when it is detected that a pachinko ball has won by a sensor provided at each winning opening. The payout control device 61 includes a memory, in which data indicating the number of payout balls for a single pachinko ball for each winning opening is stored. When a winning occurs at any of the winning openings, the payout control device 61 drives a storage device in which payout pachinko balls are stored, and causes the number of pachinko balls to be paid out according to the type of winning opening.

  The movable member control device (movable control device) 62 is connected to a solenoid 64 that drives the movable member 15 a of the start winning opening 15. The movable member control device 62 is activated when a pachinko ball wins the start winning opening 15. The movable member control device 62 drives and controls the solenoid 64 so that the movable member 15a is held at the open position for 0.5 seconds in the normal mode, and the movable member 15a is held at the open position for 2 seconds in the time reduction mode. The solenoid 64 is driven and controlled as described above. The movable member control device 62 is also connected to a solenoid 65 that drives the ball guiding member 48. The movable member control device 62 drives and controls the solenoid (movable device) 65 so that the ball guiding member 48 is located at a position where the ball can flow down in the normal mode and the hit mode, and the ball guiding member 48 is located at a position where the ball guiding member 48 cannot flow down in the time reduction mode. To do. Further, although not shown in detail, the movable member control device 62 is also connected to a solenoid for driving the attacker 15. By driving this solenoid, the position where the attacker 15 opens the big prize opening 17 and the big prize opening 17 are set. Rotate between closed position.

  The launch control device 63 is connected to the launch handle 10a. When the launch handle 20 is operated, the launch control device 63 launches the pachinko balls at regular intervals according to the launch strength of the pachinko balls adjusted by the launch handle 20. .

  Next, the operation of the pachinko machine 10 will be described. In the pachinko machine 10, a game in the normal mode is first performed. When the player operates the launch handle 20 and a pachinko ball is launched into the game area on the front side of the game board 12a, is the launched pachinko ball awarded to either the start winning opening 15 or the normal winning opening 16? Enter the outlet 18.

  When the hit pachinko ball enters the ball entrance 34 of the center accessory 19, the pachinko ball falls into the base member 40 of the upper ball passage member 32. The fallen pachinko sphere of the base member 40 flows down either the main passage 43 or the branch passage 44 and enters the sphere inlet 33 a of the spiral sphere passage member 33 from the sphere outlet 42. Pachinko balls that have flowed down the branch passage 44 pass through the passage gate 47 and are detected by the passage gate sensor 58. When detection by the passage gate sensor 58 is performed, a detection signal is input to the CPU 53. In response to this, the CPU 53 operates the lamp control device 60 to turn on the lamp 23 and the lamp 32a for a predetermined time and also operates the winning advantage lottery section 57.

  In the winning advantageous lottery section 57, whether or not the movable member 15a is rotated from the closed position to the open position is determined by winning advantageous lottery. When the winning advantageous lottery is performed, the CPU 53 activates the symbol display control device 59, and notifies the player of the winning advantageous lottery result from the symbol display device 14 by displaying, for example, characters or patterns. At the same time, the CPU 53 operates the movable member control device 62. The movable member control device 62 drives the solenoid 64, rotates the movable member 15a from the closed position to the open position, and holds it at the open position for 0.5 seconds. This makes it easier for the pachinko ball to win the start winning opening 15, so whether or not the pachinko ball has passed through the passage gate 47 is one of the players' interests. Therefore, it is possible to visually recognize whether the pachinko ball has passed through the passage gate 47 through the transparent window 41a, and further, this is notified by lighting of the lamp 23 and illumination of the passage fluoroscopic member 41 by the lamp 32a. The person can be interested in the movement of the pachinko ball. In addition, a sensor for detecting a pachinko ball is provided between the branch portion and the passage gate 47, and the pachinko ball passes through the passage gate 47 in advance by lighting the lamp 32a based on the detection of the sensor. May be. Thereby, the visibility of the pachinko sphere can be improved by turning on the lamp 32a until the pachinko sphere passes through at least a little before the passage gate 47 passes. Can be clearly notified, and the player's interest in observing the passing gate 47 from the transparent window 41a can be attracted.

  The pachinko balls that have entered the ball inlet 33a of the spiral ball passage member 33 flow down the ball passage 33b and then flow down to the stage 31 from the ball outlet 33c. The pachinko ball of the stage 31 falls from the stage 31, or enters the stage ball inlet 31a and falls from the stage ball outlet 31b.

  When a pachinko ball wins at the start winning opening 15, a winning determination lottery is performed by the winning determination unit 55 and a combination of symbols to be stopped and displayed by the stop symbol determining unit 56 is determined. Then, the symbol display device 14 is actuated to perform symbol variation display and stop display.

  When the winning determination unit 55 determines the winning, the symbol stop display is performed so as to display the winning and the normal mode is changed to the winning mode. In the hit mode, the attacker 17 is moved between a closed position and an open position. In the winning mode, the grand prize opening is opened 15 times. The opening of the grand prize opening is completed for 30 seconds or when 10 pachinko balls are won in the big prize opening. When the hit mode ends, the CPU 53 shifts to the time reduction mode.

  In the time reduction mode, the symbol display control device 50 makes the time from the start of the symbol variation display to the symbol stop display shorter than that in the normal mode. For this reason, a game can be performed efficiently in the time reduction mode. In the time reduction mode, the movable member control device 62 controls the solenoid 64 to drive the ball guiding member 48 to the position where it cannot flow down, so that all the pachinko balls that have entered the ball inlet 34 flow down the branch passage 44. Thereby, the number of times that the winning advantageous lottery is performed in the time reduction mode is larger than that in the normal mode. When the winning advantageous lottery is won, the movable member control device 62 holds the movable member 15a in the open position for 2 seconds. For this reason, in the time reduction mode, it becomes easier to win a pachinko ball in the start winning opening 15 than in the normal mode, which is advantageous in acquiring the pachinko ball. The time reduction mode is terminated when the symbol variation display is performed a predetermined number of times, and the mode is shifted to the normal mode. Note that the number of times that the movable member 15a is held at the open position for one detection of the pachinko ball may be set to an appropriate number.

  In the above embodiment, the time for which the movable member 15a is held in the open position in the time reduction mode is set longer than that in the normal mode. However, for example, the time for which the movable member 15a is held in the open position in the probability variation mode is increased. The time for which the member 15a is held in the open position may be appropriately set according to the gaming state. In addition, when the ball guiding member 48 is moved between the flowable position and the flowable position, for example, the ball guiding member 48 is always moved in the normal mode and held at the position when the probability change mode is entered, or When a specific lottery is won, an appropriate opportunity may be set, such as when the number of times the symbol variation display has been performed in the normal mode or the time reduction mode reaches a predetermined number.

  In the above-described embodiment, only the branch passage 44 is provided and one path for the pachinko balls to flow down is provided in addition to the basic passage 43. However, the number of branch paths provided may be appropriately set.

  In the above embodiment, the passage gate 47 is provided in the branch passage 44 to detect the pachinko ball that has passed through the branch passage 44, but a passage gate may be provided in both the main passage 43 and the branch passage 44. In this case, the lottery probability of the winning advantageous lottery may be higher when a pachinko ball is detected in one passage than when it is detected in the other passage. The lottery performed when a pachinko ball is detected at the passing gate may be performed as appropriate.

  In the above-described embodiment, the ball guiding member 48 is positioned at the flowable position in the time reduction mode. For example, when the ball guiding member 48 is shifted to the time reduction mode, the ball guide member 48 is constant at certain intervals between the flowable position and the flowable position. A lottery is performed to determine whether or not to move the ball guide member 48 in the short-time mode, which is movable in the movable range, and is moved when the lottery is won. For example, an appropriate trigger may be set as the trigger for moving the ball guide member 48, such as moving the ball guide member 48 within a fixed movable range at regular intervals.
