Description

  The present invention relates to a pachinko gaming machine having a special winning opening.

  Conventionally, a random number is acquired when a game ball wins a start opening, and when the acquired random number corresponds to a jackpot random number value, a predetermined number of rounds are opened for the big winning opening (attacker) and a predetermined number is set for each round. A pachinko gaming machine is known that allows a number of game balls to be won and a large number of game balls to be paid out.

  The big prize opening of this type of pachinko gaming machine has a pivoting door that can pivot in the front-rear direction, and the pivoting door normally pivots rearward and is substantially flush with the game board surface. It is in a closed state that prevents the winning of game balls, and when a big hit occurs, it turns forward and protrudes from the surface of the game board, accepting the falling game ball and allowing it to win Then, it is controlled to repeat a predetermined number of rounds alternately from the open state to the rear, turning into a state that is substantially flush with the game board surface and preventing the game ball from being won.

  However, the conventional prize opening can realize various opening / closing patterns by appropriately selecting the opening time and closing time of the rotating door, but the opening / closing pattern is determined only by opening / closing the rotating door, The impression given to the player by the opening / closing operation of the big prize opening is relatively low.

  The present invention has been made paying attention to the above-mentioned problems, and a first object of the present invention is to provide a prize winning opening that can perform an opening / closing operation with a high impression level for a player.

  Also, in a pachinko machine equipped with a big winning opening, as a big win, during the big hit, it is almost impossible to win a game ball to the big winning opening, and after the big hit, it will go to a probabilistic gaming state that generates a big win with a high probability In addition to newly setting the latent probability variation jackpot to be transferred, a new small bonus is provided as a loss, and when the latent probability variation jackpot occurs, the winning prize opening is intermittent for a predetermined number of rounds (for example, 15 rounds) for an extremely short time (for example, 0.1 seconds). When a small hit occurs, the big prize opening is opened in the same manner as when the latent probability change big hit occurs, that is, it is opened intermittently for a predetermined number of times (for example, 15 times) for an extremely short time (for example, 0.1 second). There is a pachinko gaming machine that performs control and notifies the player that either a latent probability variation big hit or a small hit has occurred.

  However, the event that the big prize opening becomes open will cause the player to expect the possibility of winning the big prize opening. Since the opening time is extremely short, the player continuously performs a game ball launch operation without expecting a prize, and some players temporarily interrupt the launch operation.

  The present invention has been made paying attention to the above-mentioned problems, and it is possible to give a player a chance to win a grand prize opening even if the opening time of the big prize opening is extremely short. The second purpose is to provide a grand prize opening that can be expected.

  The pachinko gaming machine of the present invention is a pachinko gaming machine having a movable member at the upper end and a large winning opening having a rotating door below the movable member, the movable member protruding forward from the surface of the game board. There are two states: a forward state in which the game ball is not guided to the revolving door, and a retreat state in which the game ball is stored rearward from the game board surface and is guided to the revolving door. The game ball guided to the moving door is configured to take two states, that is, an open state in which a prize can be won and a closed state in which a prize cannot be won.

  According to the present invention, since the opening / closing pattern of the big prize opening is determined by combining the advance / retreat pattern of the movable member and the opening / closing pattern of the rotary door, the opening / closing operation with a high impression degree can be performed to the player.

  Here, the pachinko gaming machine alternates a predetermined number of times between two states, a short open state in which it is difficult to win a prize winning opening and a long closed state in which it is impossible to win a prize winning opening. The game state is configured to generate a repeated game state, and the game state is maintained by holding the movable member in a retracted state for a short time while maintaining the pivot door open for the entire period. On the other hand, it is configured to realize the closed state by maintaining the movable member in a forwardly advanced state for a long time. With this configuration, since the pivot door is maintained in the open state, the player is highly likely to win the game ball at the big prize opening even if the movable member is held in the retracted state for only a short time. And come to expect. In addition, there is a possibility that the game ball placed on the movable member when the movable member is in the forward state may fall onto the rotating door due to the backward movement of the movable member, so the game ball actually wins the big prize opening. The possibility increases.

1 is a front view of a game board of a pachinko gaming machine according to an embodiment of the present invention. It is a front view of a variable prize opening and a normal electric accessory arranged in the game board. It is the perspective view which shows the state which removed the rotation door from the variable prize opening, and the perspective view which shows the operation state of the variable prize opening.

  The lower part of the center decorative member 3 is constituted by a stage 3a. The stage 3a is formed with an entrance 3b through which a game ball guided from the board surface 1a of the game board 1 through the warp passage (not shown) to the stage 3a can enter. The entered game ball passes through a guide passage (not shown) and is discharged from the outlet 3c to the lower portion 2c of the game area 2. The stage 3a is provided with a first special symbol holding lamp 3d for displaying the maximum number of game balls held in the first starting port 6 for holding up to four.

  In the lower portion 2 c of the game area 2, a first start port 6 is disposed directly below the outlet 3 c of the center decorative member 3. A game ball can always win in the first start port 6, and the winning frequency of the game ball discharged from the outlet 3 c of the center decorative member 3 to the first start port 6 is high. The first start port 6 is provided with a first start port switch (not shown) for detecting a game ball won in the first start port 6, and a detection signal of the first start port switch is a game control board (not shown). Is input. When the game control board receives the detection signal of the first start port switch, it acquires various random numbers such as jackpot random numbers. If the jackpot random number corresponds to a predetermined jackpot random number value, the jackpot becomes a special gaming state advantageous to the player. A game state is generated.

  A second start port (electrical chew) 7 is disposed below the first start port 6. The second starting port 7 is normally kept closed, and winning of the game ball is prevented. The second start port 7 can be opened when a game ball passes through a gate, which will be described later, and the game ball can be won. The second start port 7 is provided with a second start port switch (not shown) for detecting a game ball won in the second start port 7, and a detection signal of the second start port switch is input to the game control board.

A. Grand prize opening 100
A large winning opening 100 is disposed obliquely above the second start opening 7.

  The special winning opening 100 has a board portion 22 fixed to the game board surface 1 a with screws 21.

  The big winning opening 100 has a winning ball passing hole 23 formed in the lower portion of the board portion 22, and the winning ball passing hole 23 guides the game ball won in the big winning opening 100 to the back side of the game board 1. . On the back side of the game board 1, there is provided a variable winning port switch (large winning port switch, not shown) for detecting the gaming ball passing through the winning ball through hole 23 and inputting a detection signal to the game control board. It is done. When the game control board receives the detection signal of the variable prize opening switch, it controls to pay out a predetermined number of prize balls. In addition, a slanted long hole (movable member advance / retreat hole) 22 a that is inclined gently toward the second start port 7 is formed at the upper end portion of the substrate portion 22. A plate portion 24a of the movable member 24 is inserted into the movable member advance / retreat hole 22a, and the plate portion 24a can be moved forward and backward through the movable member advance / retreat hole 22a. When the plate portion 24a is in the forward state, in other words, when the movable member 24 is in the forward state, as shown in FIG. 3A, the movable member 24 protrudes forward from the game board surface 1a, and the game ball is movable. It is received by the member 24 and can flow down obliquely toward the second starting port 7 along the upper surface of the movable member 24. Further, when the plate portion 24a is in the retracted state, in other words, when the movable member 24 is in the retracted state (stored state), the movable member 24 is retracted into the game board surface 1a as shown in FIG. The game ball can fall downward without interfering with the movable member 24. On the front surface of the substrate portion 22, left and right side wall portions 25a and 25b are projected in parallel. A rotating door 26 that opens and closes the winning ball passing hole 23 is attached to the lower end portion of the substrate portion 22 so as to be rotatable in the front-rear direction. When the pivot door 26 pivots rearward and is in the closed state, the pivot door 26 is substantially flush with the game board surface 1a and prevents the game ball from winning the winning ball through hole 23, while the pivot door 26 is pivoted. When the door 26 pivots forward and is in the open state, the pivot door 26 protrudes forward from the game board surface 1a, receives the falling game ball, and can enter the winning ball through hole 23 To.

  The forward and backward movement of the movable member 24 is controlled by the movable member driving device 27. As shown in FIG. 4, the movable member driving device 27 is attached to a solenoid (movable member solenoid) 28, a locking portion 29 provided at the tip of the plunger 28a of the movable member solenoid 28, and an outer periphery of the plunger 28a. And a coil spring 30 that constantly applies a forward pressing force to the locking portion 29, and the locking portion 29 is locked in a locking hole 24 c provided in the rear wall portion 24 b of the movable member 24. The Energization of the movable member solenoid 28 is controlled by a control signal from the game control board, and the movable member driving device 27 and the movable member 24 are in the state shown in FIG. The member driving device 27 and the movable member 24 are in the state shown in FIG. The normal state shown in FIG. 4A is a state in which the locking portion 29 has been advanced by the pressing force of the coil spring 30, and the movable member 24 has been advanced, so that the winning of the game ball into the big winning opening 100 is prevented. The On the other hand, the state shown in FIG. 4B is a state in which the plunger 28a is retracted by energizing the movable member solenoid 28, the movable member 24 is in the retracted state, and the game ball is in the open state. It is possible to win a prize in the big winning opening 100 of the.

  The turning of the turning door 26 in the front-rear direction is controlled by a turning door driving device 31 configured in the same manner as a well-known big prize opening driving device. As shown in FIG. 5, the revolving door drive device 31 applies a turning force (closed drive force) in a direction to close the winning ball passing hole 23 to the solenoid (revolving door solenoid) 32 and the revolving door 26. And a releasable actuating member 33, and a coil spring (not shown) that exerts an elastic biasing force on the actuating member 33 so that the actuating member 33 can act on the rotating door 26 with a normally closed driving force. The turning door solenoid 32 operates the actuating member 33 against the elastic biasing force of the coil spring when energized, and the closing driving force acting on the turning door 26 disappears. The energization of the revolving door solenoid 32 is controlled by a control signal from the game control board, and the revolving door driving device 31 and the revolving door 26 are in the state shown in FIG. When energized, the pivot door driving device 31 and the pivot door 26 are in the state shown in FIG.

B. Game Operation Next, the basic operation of the pachinko gaming machine configured as described above will be described.

(1) Normal Game State In the normal game state, the player operates the handle so that the launched game ball rolls and falls on the left portion 2a of the game area 2. A game ball that rolls and falls on the left side portion 2a of the game area 2 moves to the lower portion 2c of the game area 2 or can enter the first start port 6 through the stage 3a.

  When the game ball wins the first start port 6, the game control board acquires various random numbers including a jackpot random number on condition that the number of reserved game balls won to the first start port 6 is less than four. A jackpot determination process is performed. When it is determined in the jackpot determination process that the acquired jackpot random number corresponds to the predetermined jackpot random number value, the special symbol display unit 11 displays the special symbol in a variable manner and the display screen 4 displays the decorative symbol variation display and the reach effect, etc. After the performance is performed, the special symbol is changed and stopped at the jackpot symbol, and the display screen 4 is displayed that the jackpot has occurred, and the jackpot gaming state is generated.

  In the pachinko gaming machine, there are two types of jackpots, a long jackpot and a short jackpot, and the long jackpot has two types of jackpots (for example, 15 round probability jackpots) and normal jackpots (for example, 15 rounds jackpots). There is a long win, a short win has one type of short hit, a probabilistic big hit (latent probability change big hit), and there is a small win in lose. The probable jackpot per long is that the big winning opening 100 is intermittently opened by a predetermined number of rounds (for example, 15 rounds) in the big winning gaming state, and a predetermined number of game balls are opened in each round. It is possible to pay out a large number of prize balls after winning a prize, and the gaming state after the jackpot is a high probability of winning a big hit, and a high probability of hitting and the second starting point in a single hit 7 is a jackpot that results in a probabilistic gaming state in which the opening time and the number of times of opening increase compared to the normal time. In addition, the normal jackpot per long is the jackpot 100 that is intermittently opened for a predetermined number of rounds (for example, 15 rounds) in the jackpot gaming state, as in the case of a promising jackpot, so that a large number of prize balls can be paid out. Thus, the game state after the jackpot is the same as the probability variation jackpot, and the probability of hitting is high and the opening time and the number of times of opening the second starting port 7 per hit increase compared to the normal time, but the probability variation jackpot Unlike the jackpot, the jackpot that becomes a short game state when the jackpot is generated with low probability. In addition, in the latent probability variation jackpot, during the big hit, the big winning opening 100 is intermittently opened for a predetermined number of rounds (for example, 15 rounds) for a short time (for example, 0.1 seconds). Although it is almost impossible to win a game ball, the game state after the jackpot is a big chance that a big hit will occur, a low chance that a win will occur, and the second start port 7 will be opened in a single hit It is a jackpot that will result in the same gaming state as the normal time and the number of times of opening. In addition, in the small hit, during the small hit, the winning prize opening 100 is intermittently opened for a predetermined number of times (for example, 15 times) with a substantially the same opening / closing pattern as the latent probability variation jackpot, At each opening, it is almost impossible to win a game ball in the big winning opening 100, and the gaming state after the big hit ends is a loss that causes a big hit with a low probability as before the small hit.

(2) Probability jackpot gaming state and normal jackpot gaming state In the probability variation jackpot gaming state and normal jackpot gaming state, the winning prize opening 100 is intermittently opened for a predetermined number of rounds. The opening / closing operation of the special winning opening 100 is performed, for example, by synchronizing the energization and deenergization of the movable member solenoid 28 with the energization and deenergization of the rotary door solenoid 32. That is, by simultaneously energizing the movable member solenoid 28 and the rotary door solenoid 32, the movable member 24 is retracted and opened, and the rotary door 26 is rotated forward and opened. The falling game ball passes through the front of the movable member 24 and is received by the rotary door 26, and can enter the winning ball through hole 25, and is also connected to the movable member solenoid 28 and the rotary door solenoid 32. By stopping energization at the same time, the movable member 24 moves forward and closes, and the pivot door 26 pivots rearward and closes. The game ball falling from above is received by the movable member 24. Then, it flows down on the upper surface of the movable member 24 toward the second starting port 7. Alternatively, the energization of the movable member solenoid 28 is continued and the movable member 24 is kept in the open state, and the energization of the rotating door solenoid 32 for a long time and the short-time energization stop are alternately repeated. You may control to. In the probability variation jackpot game state and the normal jackpot game state, the player starts to hit the right side, so that the game ball fired on the left portion 2a of the game area 2 passes through the right-handed ball path 5 and plays the game. It rolls and falls to the lower part 2c through the right part 2b of the area 2, and in each round, a game ball can be won in the open big prize opening 100, and a predetermined number of game balls are put in the big prize opening 100. Wins and a lot of prize balls are paid out.

(3) When the latent probability variation jackpot or small hit occurs When the latent probability variation jackpot occurs or when a small hit occurs, the big winning opening 100 is intermittently opened for a short time and a predetermined number of times. . The opening / closing operation of the special prize opening 100 is performed by alternately repeating the short-time energization to the movable member solenoid 28 and the energization stop in a state where the energization to the rotary door solenoid 32 is continuously performed. Is called. That is, when the latent probability variation big hit or small hit occurs, the rotary door 26 is rotated forward by the energization of the rotary door solenoid 32 and maintained in the open state, and intermittently applied to the movable member solenoid 28. The movable member 24 moves backward by a short time energization and is opened for a short time.

  As described above, when the latent probability variation big hit or the small hit occurs, the rotary door 26 is maintained in the open state, and the movable member 24 intermittently repeats the short-time open state. For this reason, it is almost impossible to win a game ball in the big winning opening 100, but the rotating door 26 is maintained in the open state, so that the player can change the latent probability by the open rotating door 26. It can be easily recognized that either a big hit or a small hit has occurred.

(4) Probability gaming state or short-time gaming state In the probability-changing gaming state after the probability-changing jackpot end or the short-time gaming state after the regular jackpot end, the player makes a right-handed game that is fired to the left portion 2a of the gaming area 2 The ball passes through the right-handed ball passage 5 and rolls and falls on the right side portion 2b of the game area 2. A part of the game ball rolling and falling on the right portion 2 b of the game area 2 passes through the gate 10.

  When the game ball passes through the gate 10, the game control board acquires a hit random number on the condition that the number of reserved game balls that have passed through the gate 10 is less than four, and performs a hit determination process. When it is determined in the winning determination process that the acquired winning random number corresponds to a predetermined winning random number value (the winning probability in the probability variation gaming state and the short-time gaming state is set to a high probability of 9/10, for example). After the normal symbol is variably displayed on the normal symbol display 13, the normal symbol is variably stopped at the winning symbol and a hit state is generated.

  In the hit state, the game control board performs control to open the second start port 7 intermittently for a predetermined time. For example, the opening time for one time is set to 1.80 seconds, and the opening is performed three times. In the probability variation gaming state or the short-time gaming state, the special winning opening 100 is maintained in the closed state, and the movable member 24 is in the forward movement state. Therefore, the game ball that has dropped from above the winning prize opening 100 is received by the movable member 24 and flows down on the upper surface of the movable member 24 toward the second starting port 7. For this reason, most of the game balls received by the movable member 24 are awarded to the opened second start opening 7.

  When the game ball wins the second start port 7, the game control board acquires various random numbers including a big hit random number on condition that the number of reserved game balls won to the second start port 7 is less than four. A jackpot determination process is performed. When it is determined in the jackpot determination process that the acquired jackpot random number corresponds to the predetermined jackpot random number value, the special symbol display unit 11 displays the special symbol in a variable manner, and the display screen 4 displays the decorative symbol variation display and reach effect, etc. After the performance is performed, the special symbol is changed and stopped at the jackpot symbol, and the display screen 4 is displayed that the jackpot has occurred, and the jackpot gaming state is generated.

  As described above, the pachinko gaming machine according to the present embodiment is a pachinko gaming machine including the big winning opening 100 having the movable member 24 at the upper end portion and the rotating door 26 below the movable member 24, The movable member 24 has two states: a forward state that protrudes forward from the game board surface 1 a and does not guide the game ball to the rotating door 26, and a backward state that is stored rearward from the game board surface 1 a and guides the game ball to the rotating door 26. In addition, the revolving door 26 is configured to take two states, that is, an open state in which the game ball guided to the revolving door 26 can be won and a closed state in which the winning is impossible.

  According to the pachinko gaming machine according to the present embodiment, since the opening / closing pattern of the special winning opening 100 is determined by combining the advance / retreat pattern of the movable member 24 and the opening / closing pattern of the rotary door 26, the degree of impression is given to the player. High open / close operation can be performed.

  In addition, the pachinko gaming machine according to the present embodiment has two states of a predetermined number of times, a short open state in which it is difficult to win a prize winning opening 100 and a long closed state in which a prize winning is impossible. The game state is configured to generate alternately repeated game states. The game state is maintained by holding the movable member 24 in a retracted state for a short time while maintaining the rotating door 26 in the open state for the entire period. On the other hand, it is configured to realize the closed state by maintaining the movable member 24 in the forward state for a long time. With this configuration, since the pivot door 26 is maintained in the open state, the player may win a game ball at the big winning opening 100 even if the movable member 24 is held in the retracted state for only a short time. Expected to be high. In addition, when the movable member 24 is in the forward state, the game ball placed on the movable member 24 may fall onto the rotating door 26 due to the backward movement of the movable member 24. The possibility that a game ball will win increases.

  Furthermore, the pachinko gaming machine according to the present embodiment has the following effects when the game area 2 is reduced along with the enlargement of the display screen 4 and the center decoration member 3. That is, in the probability variation gaming state or the short-time gaming state, the game ball is received by the movable member 24 provided at the upper end portion of the big winning opening 100, and is guided to the second starting port 7 on the downstream side. It is possible to set the height position of the second start port 7 on the basis of the height position of the movable member 24 and raise it to a height position close to the height position of the movable member 24. For this reason, the vertical dimension in the arrangement area of the big winning opening 100 and the second start opening 7 may be small so as to correspond to the reduced game area 2, and the big winning opening 100 is closed. In addition, it is possible to guide the game ball to the second starting port 7.
