Description

  The present invention relates to a pachinko machine, and more particularly, to a pachinko machine provided with a winning rate adjustment mechanism for adjusting a winning rate of a big winning opening.

  At pachinko halls, depending on the sales method, the average number of balls (pachinko machines) and the number of balls that are out of play (number of hits) per base (progression rate excluding jackpots) The ratio of (the number of award balls) is adjusted, and in this case, the specification of the model cannot be changed basically. Therefore, the nail (game nail) provided on the game board is adjusted. In this game board nail adjustment, there is an operation of adjusting the game nails around the big prize opening to adjust the ratio of the game balls guided to the big prize opening (winning rate). In the example of the game board 300, the two game nails 308 arranged near the upper side of the right and left edge portions of the big prize opening 306 are bent and adjusted at the base with respect to the variable prize device 304 arranged at the lower part of the game area 302. Then, the winning rate adjustment of the big winning opening 306 is adjusted mainly by tilting in the left-right direction in the figure.

  However, nail adjustment requires a high level of skill and proficiency.In particular, high accuracy is required for nail adjustment, which affects the winning rate of the big prize opening, which is important for hall management. It has become. For this reason, it is difficult to adjust all the platforms in the hall uniformly, or to adjust to the desired state for each platform, and it is also possible to adjust other game nails such as the start opening, various winning openings, and the vicinity of the accessory It takes a lot of time to work.

Therefore, in order to facilitate the adjustment of the nail regarding the winning rate of the big winning opening, the distribution nail provided directly above the variable winning device (variable winning device) is linearly arranged at a predetermined interval through which the game ball can pass. Is arranged in a multi-stage (two stages) in the vertical direction, and by adjusting the inclination of the distribution nail arranged on the upper stage side, it is possible to adjust the winning rate of the big prize opening It has been proposed (see Patent Document 1).

  However, even in the case of the above-mentioned Patent Document 1, since it is necessary to adjust the inclination of the upper nail, it is necessary for the operator to adjust each unit to a desired state or even to each table to some extent. Skill and proficiency are required, and the adjustment takes longer work time.

  In view of the above facts, an object of the present invention is to provide a pachinko machine that can easily and quickly adjust the winning rate of a big winning opening with high accuracy.

  In order to achieve the above-mentioned object, the invention according to claim 1 is characterized in that a game board provided with a game area in which a game ball is driven and dropped by its own weight and a game area provided in the game area is placed in a predetermined game state. A pachinko machine that pays out a predetermined number of prize balls when a game ball falling in the game area wins the big prize opening. A guiding member that is disposed above the grand prize winning port and changes the falling direction of the gaming ball when a gaming ball falling toward the big winning prize jack collides, and provided in the variable prize winning device, the guiding member The guide board is slidably supported only in a predetermined direction along the board surface of the game board, and a fixing means for fixing the guide member to the variable prize device.

  According to the first aspect of the present invention, the player plays a game by operating a pachinko machine, driving a game ball into the game area of the game board, and dropping the game ball in the game area by its own weight. As the game progresses, when the pachinko machine enters a predetermined gaming state such as a small role or a major role, the variable winning device provided in the gaming area changes the large winning opening from the closed state to the open state. A guiding member is disposed above the special winning opening, and when a game ball that falls in the gaming area toward the large winning opening collides with the guiding member, the direction of the gaming ball changes. Here, a game ball whose fall direction has been changed to a direction closer to the grand prize opening has a higher probability of winning in the big prize opening or winning in the big prize opening, and the falling direction can be changed to move away from the big prize opening. There is a high probability that the game ball will not win the big prize opening or will not win the big prize opening. Then, when a game ball wins a prize winning opening, a predetermined number of prize balls are paid out from the pachinko machine.

In such a pachinko machine, in order to adjust the winning rate of the big prize opening, the guiding member arranged above the big prize opening is moved and the position is changed.

  Next, the gaming procedure and operation of the pachinko machine 10 according to the present embodiment configured as described above will be described.

  In a game using the pachinko machine 10, when the player operates the launch handle 34, the game balls stored in the ball tray portion 28 of the integrated dish 30 are shot one by one by a ball feeder (not shown). And fired upward by the launcher (in the direction of arrow C in FIG. 2). The launched game ball BL is driven into the game area 101 of the game board 100 along the outer rail 102, and hits the game nail and changes its direction and falls within the game area 101 by its own weight. Then, the game ball that has reached the lower end of the game area 101 without winning a prize is collected into the pachinko machine 10 from the out port 124.

  Further, when the game ball wins the winning opening 118, the ball payout device in the pachinko machine 10 operates to pay out a predetermined number (for example, five) of the winning balls, and the discharged winning balls become the winning ball discharge port 46. To the ball tray portion 28.

  Further, when winning the start opening 110, a lottery process of winning / losing is executed in the control unit (main control board) in the pachinko machine 10, and the lottery result is arranged on the display screen 108 of the special symbol display device 106. A plurality of special symbols are changed in a predetermined pattern and displayed by a combination of stop symbols that have passed through the changed pattern. In addition, for this special symbol variation pattern, for example, a number of patterns that take various effects and tastes into consideration, such as the display of a winning symbol after reach, a display of a missed symbol, or a missed symbol display without reach, are prepared. The player receives these effects and observes the lottery result of the special symbol with expectation.

  Then, when the lottery result is “big hit”, a combination of predetermined predetermined winning symbols such as “555” is displayed on the display screen 108 of the special symbol display device 106 through a reach action, for example. In addition, the player is notified that the jackpot has occurred by adding effects such as blinking of the indicator lamp 80 and output of sound effects from the speakers 86 and 88, and executes a predetermined jackpot operation.

  As the jackpot operation, the grand prize winning hole 114 is opened, for example, 10 counts (number of winning prizes) or a maximum of 30 seconds (one opening time) / up to 16 rounds (continuous number of times) and one big winning opening 114 is opened. Occasionally, the next round is continued by winning a prize in the V zone in the big prize opening 114.

  Here, with respect to winning the opened big winning opening 114, in the pachinko machine 10 of the present embodiment, the guiding member 166 of the winning rate adjusting mechanism 150 is arranged near the upper portion of the large winning opening 114 (FIG. 2), when the game ball BL falling toward the big prize opening 114 in the game area 101 collides with the ball guide portion 168 of the guide member 166, the fall direction of the game ball BL changes. Here, the game ball BL whose direction of dropping has been changed to approach the grand prize opening 114 has a higher probability of winning in the big prize opening 114 or winning in the big prize opening 114, and the falling direction from the big prize opening 114 is increased. There is a high probability that the game ball BL changed in the direction of moving away will not win the big prize opening 114 or will not win the big prize opening 114. Then, when the game ball BL wins the big prize opening 114, for example, the player can acquire a large number of prize balls by receiving 15 payouts per winning prize.

  In addition, when the winning symbol is a combination of predetermined specific symbols such as “777”, for example, the “probability changing function” in which the next jackpot probability is increased after the above-described jackpot operation ends, or Although the jackpot probability does not change, the rotation time of the normal symbol display device is shortened, and an additional function such as a “short-time function” that makes the starting port 110 easy to open and improves the ball holding time is activated, and a gaming state advantageous to the player is achieved.
